Isolation and antimicrobial activity of lactic acid bacteria from the traditional fermented food cangkuok semaung in Riau, Indonesia
type: item
description: Fermentation can be an effective step in addressing postharvest handling challenges and enhancing nutritional value through the conversion of perishable crops into more stable products. One of the traditional fermented foods originating from Kuantan Singingi Regency, Riau Province, Indonesia, is cangkuok semaung (CS). This food is prepared by fermenting all fruit components of the semaung (Pangium edule). This research aimed to isolate and identify lactic acid bacteria (LAB) from CS and investigate their antimicrobial properties. The bacteria were isolated from the food, purified using the quadrant streak method on the De Man–Rogosa–Sharpe agar, and continued with morphological analysis and antimicrobial activities evaluation. The findings of this study revealed that 45 isolates were gram-positive bacteria identified as Lactobacillus sp. Among the LAB isolates, the highest antimicrobial activity against Escherichia coli, Staphylococcus aureus, Acinetobacter baumannii, and Klebsiella pneumoniae were shown by isolates of S12, S14, S27, and S24, respectively. These results suggest that LAB from CS, especially isolates S12 and S14, have promising antimicrobial properties and show potential as probiotic candidates that merit further investigation into possible applications in food and health sectors.

Dominant genera of plant-parasitic nematodes in kepok banana (Musa acuminata x balbisiana) cultivation in Pidie, Indonesia
type: item
description: Banana (Musa spp.) is a vital agricultural commodity in Indonesia. In Pidie Regency, Aceh, Indonesia, production declined significantly by 46% between 2021 and 2023, partly due to infestations by plant-parasitic nematodes. This study aimed to identify the dominant genera of parasitic nematodes in the kepok banana (Musa acuminata × balbisiana) cultivar grown in Padang Tiji District, Pidie, Indonesia, using soil samples collected from three villages. Four nematode genera were identified: Pratylenchus, Helicotylenchus, Meloidogyne, and Xiphinema. Pratylenchus was dominant in Tunong Tanjong and Keupula Tanjong fields, while Helicotylenchus predominated in Tuha Peudaya. The highest nematode abundance was recorded in the Tunong Tanjong field, averaging 33,973.4 individuals per 10 g of soil. These findings provide valuable baseline data for nematode pest management and support the development of targeted control strategies to enhance sustainable banana cultivation in the region.

Effects of leachate-based liquid organic fertilizer on soil fertility and chili growth in biochar-amended marginal soil
type: item
description: Soil fertility degradation and limited access to sustainable inputs pose major constraints in marginal agricultural lands. Organic waste leachate, although rich in nutrients, often contains phytotoxic compounds that limit its direct application as fertilizer. This study evaluated the effect of leachate-based liquid organic fertilizer (LOF) on soil fertility and the growth response of chili pepper (Capsicum frutescens) in marginal soils amended with biochar. Four treatments were tested: no LOF, 20% LOF, 40% LOF, and 60% LOF. Soil analysis showed that LOF application improved pH, organic carbon, and macronutrient content (N, P,K), with the highest pH in the 20% LOF treatment and the highest C-organic in the 60% LOF treatment. However, the best plant growth was observed in the control treatment, possibly indicating inhibitory effects of phytotoxic compounds such as phenols and organic acids present in the LOF. Although 20% LOF resulted in the highest fruit weight, differences among treatments were not statistically significant. These results suggest that while leachate-based LOF enhances soil quality, its high concentration may hinder plant growth. The findings support the potential use of leachate as a low-cost nutrient source for sustainable agriculture, provided that proper detoxification and formulation strategies are applied.

Sustainable vegetable production through pakchoi (Brassica rapa L.) growth response to bio-slurry liquid organic fertilizer intervals
type: item
description: Pakchoi (Brassica rapa L.) is a fast-growing leafy vegetable with high nutritional value, making it an important crop for sustainable vegetable production. However, its cultivation often relies on chemical fertilizers, which are costly and environmentally detrimental. Bio-slurry liquid organic fertilizer (LOF), a nutrient-rich by-product of biogas production, offers a sustainable alternative. This study aimed to evaluate the growth response of pakchoi to different application intervals of bio-slurry LOF to identify the most effective schedule for improving plant performance. A non-factorial completely randomized design was employed with four treatments: P0 (control), P1 (application of 100 ml LOF every 7 days), P2 (every 9 days), and P3 (every 11 days), each replicated six times. Growth parameters, including plant height, leaf number, leaf length, leaf width, and fresh weight, were measured and analyzed using one-way ANOVA followed by DMRT at the 5% significance level. Results showed that fertilization every 9 days (P2) produced the highest plant height, leaf number, and fresh weight compared to other treatments. These findings highlight the potential of bio-slurry LOF to reduce reliance on chemical fertilizers while enhancing pakchoi growth, thereby supporting sustainable vegetable farming practices.

Microwave-assisted extraction and computational modelling of curcumin from turmeric (Curcuma longa) for sunscreen applications
type: item
description: Excessive exposure to ultraviolet (UV) radiation from sunlight can cause skin damage, including premature aging, sunburn, and increased risk of skin cancer. While synthetic sunscreen agents are widely used, concerns over their long-term safety have driven interest in natural alternatives. In this study, curcumin was extracted from turmeric rhizomes (Curcuma longa) using microwave-assisted extraction (MAE) as a potential natural sunscreen. The highest yield was obtained using ethanol as solvent (5.5%), 100 watts of microwave power (5.7%), and solvent temperature of 50 °C (7.8%). Curcumin presence was confirmed by thin layer chromatography (TLC), with Rf values from 0.63 (methanol) to 0.82 (ethanol). Fourier transform infrared (FTIR) spectroscopy showed functional groups including O–H, C–H, C=C, C=O, and C–O, along with trans-C–H benzoate vibrations. ¹H-NMR spectra supported its presence, with chemical shifts at 3.80–3.92, 6.54–7.18, and 7.31–7.49 ppm. UV-Vis analysis revealed strong absorption in the UV-A region (320–420 nm), and DFT-based computational modelling showed peaks at 276 and 405 nm. These results highlight curcumin’s potential as a photoprotective agent, supporting safer, plant-based sunscreen formulations and offering a sustainable alternative for the cosmetic industry.

Agronomic performance and sugar yield potential of seven promising sugarcane (Saccharum officinarum L.) clones in second ratoon cultivation
type: item
description: The decline in sugarcane productivity and the imbalance between sugar production and national consumption are largely attributed to the genetic degradation of long-cultivated commercial varieties and suboptimal ratoon management. This study evaluates the agronomic performance and sugar yield potential of seven promising sugarcane (Saccharum officinarum L.) clones in their second ratoon cycle. The research was conducted at the Sugarcane Research and Development Center (P3T) in collaboration with PG Krembung, PT Perkebunan Nusantara X (PTPN X), in Watesari Village, Sidoarjo, Indonesia. A randomized complete block design (RCBD) with one factor and nine treatments was employed. Statistical analysis comprised ANOVA at a 5% significance level, Least Significant Difference (LSD) test, genetic diversity analysis, and heritability estimation. The results revealed significant differences among the clones in stalk diameter, brix, stalk weight, yield, and sugar content. The JW01 UMG NX clone exhibited the highest stalk diameter (33.31 mm) and sugar recovery (11.64%), while the SB19 UMG NX clone demonstrated the highest stalk weight (165.28 tons/ha), brix (23.78 °Bx), and yield (18.79 tons/ha). Genetic diversity was low across all measured traits, but heritability values were high, suggesting a strong genetic influence. These findings indicate that JW01 UMG NX and SB19 UMG NX are highly productive and hold strong potential as candidates for new superior varieties (VUB) to support national sugar self-sufficiency.

Productivity and genetic variation of elite sugarcane (Saccharum officinarum L.) clones under dryland grumusol soil
type: item
description: Sugar production in Indonesia has declined in recent years, primarily due to climate change, extreme weather conditions, and the limited availability of high-yielding varieties. This study aimed to evaluate the productivity and genetic variation of seven elite sugarcane clones and two commercial varieties cultivated under dryland grumusol soil conditions. The research was conducted at PT Perkebunan Nusantara X, Sidoarjo, Indonesia, using a randomized block design (RBD) with nine treatments and three replications. Agronomic and yield-related parameters such as plant height, number of stalks, internodes, stalk weight, Brix value, sugar content, and crystal yield were measured. Data were analyzed using ANOVA followed by a 5% LSD test, and correlation analysis was conducted to assess inter-variable relationships. Results showed significant differences among clones in all measured traits. JW01 UMG NX exhibited the highest Brix value (24%), stem weight (106.4 tons/ha), and crystal yield (9.66 tons/ha), while SB20 UMG NX recorded the highest sugar content (9.46%). Positive correlations were observed between stalk weight and Crystal yield, while Brix values were negatively correlated with plant height. These findings indicate that the selected clones possess valuable agronomic traits and adaptability to dryland grumusol soil, making them strong candidates for future variety development

Phytoremediation potential of Avicennia marina, Rhizophora mucronata, and Bruguiera gymnorrhiza in lead (Pb) contaminated urban coastal areas
type: item
description: Heavy metal contamination in urban coastal areas poses a serious environmental threat, with lead (Pb) being one of the most persistent and hazardous pollutants. Mangrove forests, which act as natural buffers between land and sea, have the potential to mitigate heavy metal pollution through phytoremediation. This study evaluates the phytoremediation potential of three mangrove species—Avicennia marina, Rhizophora mucronata, and Bruguiera gymnorrhiza—in lead-contaminated coastal areas of Wonorejo and Gunung Anyar, Surabaya, Indonesia. Sediment, root, and leaf samples were collected using a survey method and purposive random sampling. Physiochemical analysis included soil texture, pH, electrical conductivity (EC), and Pb concentration. Pb levels in Gunung Anyar sediments reached 12.0 ppm, higher than Wonorejo’s 4.05 ppm. A. marina exhibited the highest Pb accumulation, with a bioconcentration factor (BCF) of 8.85 in roots and 6.97 in leaves. R. mucronata had a BCF of 5.75 in roots and 2.09 in leaves, while B. gymnorrhiza demonstrated a root BCF of 28.8 and leaf BCF of 28.4. Translocation factor (TF) analysis revealed that A. marina had the highest TF (1.27), indicating phytostabilization as its primary mechanism. Meanwhile, R. mucronata and B. gymnorrhiza exhibited phytoextraction characteristics due to higher metal translocation efficiency. These findings highlight the distinct phytoremediation strategies among species.

Biocontrol efficacy of endophytic bacteria from Mimosa pudica L. against Fusarium oxysporum in kepok banana (Musa acuminata × balbisiana) in vitro
type: item
description: Fusarium oxysporum f. sp. cubense (Foc) is a major fungal pathogen responsible for Fusarium wilt disease in banana plants, significantly reducing productivity and leading to substantial economic losses. This study aimed to evaluate the biocontrol potential of endophytic bacteria isolated from Mimosa pudica L. against Foc through an in vitro assay. A completely randomized design (CRD) with four treatments was employed, including a negative control (CP0), a positive control (CPF0), and two endophytic bacterial isolates from Mimosa pudica L. (BEP8 and BEP15), each with four replications. The antagonistic activity of these isolates was assessed using the dual culture method. The results demonstrated that BEP8 and BEP15 significantly inhibited Foc growth from 1 to 5 days after inoculation (DAI), with maximum inhibition rates observed on day 4, reaching 36.60% and 37.52%, respectively. These findings suggest that endophytic bacteria from Mimosa pudica possess potential as biocontrol agents against Foc. However, further molecular identification and greenhouse trials are necessary to confirm their efficacy in real-world applications.

Physicochemical characterization of coconut shell liquid smoke and its potential as a natural preservative for fish balls
type: item
description: Synthetic preservatives in food products pose potential health risks and environmental concerns, leading to an increasing demand for natural alternatives. This study evaluates the physicochemical properties of liquid smoke derived from coconut shells and its potential as a natural preservative for fish balls. The production of liquid smoke involved torrefaction at 250°C, followed by purification through distillation and adsorption with activated carbon. The liquid smoke was characterized by a pH of 2.86, a density of 1.058 g/mL, and a total titratable acidity of 8.95%, meeting the Indonesian National Standard for Crude Lignocellulose Liquid Smoke (SNI 8985:2021). GC-MS analysis revealed that acetic acid (80.87%) and phenol (8.90%) were the predominant compounds, contributing to its antimicrobial properties. The efficacy of liquid smoke as a preservative was tested on fish balls at concentrations of 3%, 5%, and 7%. The best preservation effect was observed at 7% concentration, which resulted in the lowest total plate count (2.35 × 10⁶ CFU/g) after one day of storage at room temperature. These findings suggest that coconut shell-derived liquid smoke exhibits promising physicochemical characteristics and antimicrobial properties, making it a potential natural alternative to synthetic preservatives for food preservation.

Impact of roasting temperature on the chemical composition and quality of avocado seed flour (Persea americana Mill.)
type: item
description: Avocado seeds (Persea americana Mill.) are an underutilized agricultural byproduct with significant starch content, making them a potential raw material for flour production. Roasting is a key processing method that enhances drying efficiency and improves sensory attributes. This study investigates the impact of roasting temperature (120°C, 130°C, 140°C, and 150°C) on the chemical composition and quality of avocado seed flour (ASF). The experiment was conducted using a Completely Randomized Design (CRD) with three replications. Proximate analysis and tannin content were determined through standard laboratory methods. Data were analyzed using analysis of variance (ANOVA) followed by the Least Significant Difference (LSD) test. The results indicate that the optimal roasting temperature for ASF is 150°C, yielding the following composition: moisture content (5.47±0.76%), tannin content (0.0723±0.0004%), protein content (1.66±0.033%), carbohydrate content (86.45±0.91%), fat content (2.08±0.23%), and ash content (4.34±0.03%). Higher roasting temperatures resulted in lower moisture and tannin levels, which are beneficial for improving ASF quality. This study provides valuable insights into optimizing roasting conditions for ASF production, enhancing its potential application in food processing.

Impact of dietary Sardinella lemuru fish oil supplementation on egg production and fatty acid profile of laying quails in smallholder farming
type: item
description: Smallholder quail farms often face limitations in providing high-quality feed that can improve both productivity and nutritional quality of eggs, particularly in enhancing essential fatty acids such as omega-3. Bali sardinella (Sardinella lemuru) fish oil is a rich source of omega-3 fatty acids and holds potential as a dietary supplement to enhance egg nutritional value. This study aimed to evaluate the impact of S. lemuru fish oil supplementation in feed on egg production and fatty acid profile of laying quails under smallholder farming conditions. A randomized block design was applied with four treatments: T0 (0% LFO), T1 (2% LFO), T2 (4% LFO), and T3 (6% LFO), each with two replications and 50 adult female quails per unit. The results showed that S. lemuru fish oil supplementation had no significant effect on egg weight, egg length, viscosity, yolk diameter and height, or other physical egg parameters. However, T3 significantly reduced egg production. The 2% LFO treatment (T1) resulted in the highest crude protein content in the feed and relatively better performance and physical egg quality. The fatty acid profile of eggs was dominated by oleic, palmitic, and linoleic acids, with omega-3 levels increasing in line with higher LFO doses. These findings suggest that 2% S. lemuru fish oil supplementation is suitable for smallholder quail farming to improve egg quality without significantly increasing production costs.

description: The excessive use of synthetic chemical pesticides in controlling plant diseases poses significant challenges to sustainable agriculture. As an environmentally friendly alternative, plant growth-promoting rhizobacteria (PGPR) have shown promise by colonizing plant roots and forming symbiotic relationships that enhance plant growth and suppress plant pathogens. Research on the isolation of PGPR from ginger (Zingiber officinale) rhizosphere in Indonesia remains limited, highlighting the need for further exploration to support genetic resource conservation and sustainable agricultural practices. This study aims to evaluate the potential of PGPR isolates from Z. officinale rhizosphere in Semarang, Indonesia, as biological control agents. Isolates were characterized based on morphology, biochemical traits, and their antagonistic activity against fungal pathogens, including Fusarium oxysporum, Colletotrichum sp., and Alternaria sp. A total of 14 isolates were obtained, exhibiting diverse morphological, biochemical, and antagonistic properties. Among them, isolate 235A2 demonstrated the highest potential as a biological control agent, with capabilities including phosphate solubilization, nitrogen fixation, protease enzyme production, and significant inhibition rates of F. oxysporum (13.79%), Colletotrichum sp. (55.56%), and Alternaria sp. (35.61%) in vitro. These findings underscore the potential of PGPR as a sustainable alternative for biological control of plant pathogens, supporting both enhanced plant productivity and environmental conservation.

The effect of liquid inorganic fertilizer on the growth of seven sugarcane (Saccharum officinarum L.) clones for sugar factory in Indonesia
type: item
description: Sugarcane (Saccharum officinarum L.) is a type of plantation crop that has high economic value as the main ingredient for sugar production. Indonesia's sugar demand increases every year, but it is not accompanied by an increase in sugar production. Problems that cause low sugar production include seed quality, fertilizer availability, water availability, slash-and-carry management, and inadequate soil conditions. Increasing sugarcane productivity and production is related to the level of yield production. The availability of new superior varieties (VUB) is one way that can be done to produce high sugar production. The continuous use of excessive inorganic fertilizers can cause problems in agriculture. The purpose of this study was to analyze the effect of inorganic liquid fertilizer on the growth of seven sugarcane clones (Saccharum officinarum L.) in Sidoarjo Regency, Indonesia. This research was conducted in the Sugarcane Research and Development Center (P3T) garden and in collaboration with PG Krembung PT Perkebunan Nusantara X (PTPN X) in October-January 2021. This study used a one-factor Randomized Group Design (RAK) with 9 treatments and 3 replications. Parameters observed in this study were stem diameter, stem length, and number of stems. The results showed that the growth of the K4 sugarcane clone (SB 11 clone) was higher than the K5 (PS 881 clone). Petrovita fertilizer application resulted in more optimal growth in sugarcane clone.

Evaluating chia (Salvia hispanica L.) seed administration for cholesterol reduction in quail (Coturnix coturnix)
type: item
description: Chia (Salvia hispanica L.) seeds contain phenolic compounds such as flavonols and phenolic acids (myricetin, quercetin, kaempferol, caffeic acid) that act as primary and synergistic antioxidants. These antioxidants reduce cholesterol by inhibiting absorption in the intestine and enhancing bile acid formation, facilitating cholesterol excretion through feces. Additionally, the high protein and fiber content in S. hispanica L. seeds reduces appetite and promotes prolonged satiety. This study evaluates the effect of different administration patterns of S. hispanica L. seeds on cholesterol reduction in common quail (Coturnix coturnix). The research involved five groups: three treatment groups receiving S. hispanica L. seeds at varying frequencies (once, twice, three times daily) and two controls (positive, negative), with six C. coturnix in each group. The S. hispanica L. seed dose was 1.8 mg per 200 g body weight (BW) administered for 30 days. Cholesterol levels were measured at baseline and after treatment and analyzed using one-way ANOVA and Duncan’s Post Hoc Test. Results indicated that administering S. hispanica L. seeds three times daily significantly reduced cholesterol levels (p < 0.05) compared to other frequencies. This research provides a foundation for further exploration into practical applications of S. hispanica L. seeds in cholesterol management, both in animals and potentially in humans.

Photoperiod effects on the growth stages of fall armyworm Spodoptera frugiperda (Lepidoptera: Noctuidae) under laboratory conditions
type: item
description: Spodoptera frugiperda, commonly known as the fall armyworm, is a pest that attacks maize plants in Indonesia. Light is one of the crucial factors in the development of S. frugiperda. This study aims to observe and analyze the effects of different light exposure (photoperiod) on the duration of larval instars, pupal stage, and imago, as well as the body length and weight of S. frugiperda. The expected benefit of this research is to provide insights into how light influences the developmental stages of S. frugiperda under laboratory conditions. The test insects, S. frugiperda, were obtained from Agricultural Standardization Testing Center - Sweetener and Fiber Crops (BSIP-TAS) and were reared from the first instar larval stage, with a total of 56 individuals fed with young maize cobs. S. frugiperda undergoes complete metamorphosis, passing through egg, larval, pupal, and imago stages. The treatment with no light and 24 hours of darkness (0L:24D) resulted in the shortest duration for the larval, pupal, and imago stages, averaging 27.42 days, compared to other treatments. On the other hand, the 24L:0D treatment significantly affected body length and weight, showing distinct differences from other treatments (L: light; D: dark). The effect of light, using 238.89 lux illumination, was found to influence the development of S. frugiperda at each developmental stage.

Impact of cutting types and commercial plant growth regulators on the propagation of red star begonia (Begonia rex-cultorum)
type: item
description: Begonia is an ornamental plant known for its beautiful, variegated leaves. Propagation of this plant via vegetative means, particularly using leaves, often encounters challenges such as drying, rotting, and mortality of cuttings, necessitating the use of plant growth regulators (PGRs) to support their development. This study aims to determine the optimal combination of cutting type and commercial PGR concentration for the growth of red star begonia leaf cuttings. A factorial completely randomized design (CRD) was employed with two factors: cutting type (whole leaves and leaf slices) and PGR concentration (250 ppm, 300 ppm, 350 ppm, and 400 ppm), each replicated three times. The results indicated that the best combination for leaf number, root length, primary root number, and survival rate was whole leaves with a PGR concentration of 400 ppm. For the earliest sprout emergence, the best treatment was a PGR concentration of 350 ppm. These findings can enhance the efficiency of vegetative propagation of red star begonia, reduce propagation failure rates, and provide practical guidance for growers and ornamental plant enthusiasts in selecting optimal methods and PGR concentrations.

Soil morphological characteristics in the active volcanic toposequence zone at Tangkuban Parahu volcano, Indonesia
type: item
description: Soil formation in volcanic terrains presents a significant challenge due to the diverse physical and chemical properties imparted by volcanic activity, which are not yet fully understood. This study investigates the unique morphological characteristics of soil profiles within crater topography sequences at the Tangkuban Parahu Volcano, Indonesia. To address this gap, five representative sample profiles (I, II, III, IV, V) were analyzed. The Ratu Crater pathway topography was characterized by steep to very steep slopes. Detailed analysis identified three predominant soil layers, each with distinct features such as color, texture, porosity, and chemical composition, reflecting different stages of soil formation. At the highest elevation near the crater rim, Profile V was composed mainly of volcanic ash, with a loose structure, high porosity, and acidic pH, indicative of recent volcanic deposits. Profile III, at intermediate elevations, consisted of highly weathered soil with sandy loam textures and clear layer demarcations, suggesting prolonged soil development and consolidation. Profile I, at the lowest elevation, featured loamy sand with significant weathering and organic matter incorporation, indicating advanced soil development stages. The findings underscore the impact of volcanic activity on soil morphology, revealing distinct layers that correlate with various ages and developmental stages. Understanding these processes can inform agricultural practices.

Efficacy of neem and basil leaf extracts in controlling whitefly (Bemisia Tabaci) infestations and enhancing yield in curly red chili peppers (Capsicum annuum L.)
type: item
description: Whiteflies (Bemisia tabaci) are a major pest of curly red chili peppers, acting as vectors for gemini viruses that significantly reduce crop productivity. This study evaluated the efficacy of neem and basil leaf extracts at three different concentrations for controlling whitefly infestations on chili plants. A randomized complete block design (RCBD) was employed with 8 treatments and 2 controls: PA (Neem 1%), PB (Neem 2%), PC (Neem 3%), PD (Basil 1%), PE (Basil 2%), PF (Basil 3%), PKM (commercial pesticide as positive control), and P0 (distilled water as negative control). Parameters assessed included whitefly infestation intensity, yellowing of shoots, fruit weight, total fruit count, and the number of infested fruits. The results indicate that both neem and basil leaf extracts effectively reduced whitefly infestation intensity and yellowing of shoots compared to the negative control (P0). Despite some increase in infestation intensity in subsequent observations, both neem and basil extracts positively impacted fruit yield, including higher fruit weight and total fruit count. However, there was no significant effect on the number of infested fruits with the treatments. These findings suggest that neem and basil leaf extracts are promising alternatives for managing whitefly infestations and improving yield in curly red chili peppers.

Phytoremediation of iron-contaminated soils using humic acid and hyperaccumulator grasses
type: item
description: The Lapindo mud disaster in Porong, Sidoarjo, Indonesia, resulted from mining activities, leading to severe iron (Fe) contamination in the soil. This contamination has adversely impacted agricultural productivity in the affected areas. Phytoremediation, utilizing humic acid as a chelating agent and hyperaccumulator grasses, is a potential solution to mitigate this pollution. This study employed a factorial completely randomized design (CRD) to evaluate this approach with two factors: the application of 600 ppm humic acid and the use of different grasses (vetiver, elephant grass, nutgrass, and gotu kola). Observed parameters included plant dry weight and total iron content in soil and plant tissues. These data were used to determine the bioconcentration factor (BCF), translocation factor (TF), and absorption efficiency (%). The results indicated that humic acid significantly increased plant dry weight and iron uptake in plant tissues. The combination of gotu kola and humic acid showed the highest phytoremediation potential, with a BCF of 0.3121, TF of 1.4871, and an absorption efficiency of 55.7538%. This study highlights the effectiveness of humic acid and hyperaccumulator grasses in phytoremediation of iron-contaminated soils, offering a sustainable approach to improving soil health and agricultural productivity in polluted areas.

Water balance optimization for strategic planting patterns and calendars in paddy (Oryza sativa L.) cultivation in rainfed regions
type: item
description: Paddy (Oryza sativa L.) is a staple food crop in Indonesia that requires more water compared to other annual crops. Cultivating paddy in rainfed areas necessitates effective water management to prevent crop failure, making it essential to calculate water balance, planting patterns, and planting calendars. This study aims to analyze the water balance in relation to planting patterns and calendars based on water availability in the field. The research was conducted in Cukilan Village, Semarang Regency, Indonesia. A descriptive quantitative method using Cropwat 8.0 was employed to determine water balance, planting patterns, and planting calendars. The results indicate that from November to April, there is a water surplus, while from May to October, there is a water deficit. Planting can be conducted once per growing season with two possible periods: November-March or December-April. During Period I (November-March), the water requirement is 640.7 mm with effective rainfall of 1031.2 mm. In Period II (December-April), the water requirement is 638 mm with effective rainfall of 935.7 mm. Planting should begin in November or December, with harvest in March or April. From May to October, the land remains fallow due to insufficient water availability. These findings are valuable for enhancing the effectiveness of paddy cultivation in rainfed areas, assisting farmers with planting planning, and minimizing the risk of crop failure due to water scarcity.

Optimizing winged-bean meal through oven and autoclave heating as viable alternative for plant-based aquafeed
type: item
description: Winged-bean meal can serve as a substitute for soybean meal in plant-based fish feed, despite its trypsin-inhibitor properties, which can be alleviated through heating processes. This study aimed to explore the potential of winged-bean meal subjected to different heating methods, namely oven (110 °C for 30 minutes) and autoclave (121 °C for 30 minutes), based on proximate analysis and trypsin activity. The study applied three treatments with four replications: oven heating (O), autoclave heating (A), and control (without heating, E). All data were analyzed using analysis of variance and Duncan’s multiple range test to determine the best treatment. Data were also compared to the nutrient requirements of several cultured freshwater fish in Indonesia. Heating treatments improved in vitro trypsin activity (1300 units/O and 1135 units/A vs. 835 units) but reduced protein (29.05±1.96%/A and 31.73±1.52%/O vs. 35.17±0.38%) and moisture contents. Additionally, the O treatment met the standards for aquafeed protein content (27-45%) and potentially fulfilled the protein requirements for catfish (25-40%), Nile tilapia (30-35%), and Java barb (30-32%). Therefore, oven heating presents a viable candidate as an alternative plant-based aquafeed ingredient. Nevertheless, the in vivo application of winged-bean meal as an aquafeed ingredient should be further evaluated to determine whether heating treatment effectively enhances digestive activity, nutrient retention, and growth performance in target fish species.

description: The intensive use of synthetic fertilizers in melon cultivation can reduce soil organic matter and fertility, ultimately decreasing productivity. This situation necessitates the improvement of growing media to achieve production targets through the use of rice husk charcoal and liquid organic fertilizer (LOF) from pineapple peel. This study aims to determine the combinatory effects of pineapple peel LOF and rice husk charcoal media on the growth and yield of melon plants. The research employed a factorial randomized block design (RBD) with 6 treatment levels, and data were analyzed using ANOVA followed by an HSD test at the 5% significance level. The results showed an interaction between pineapple peel POC and rice husk charcoal media on the number of leaves variable. The P0M1 treatment (positive control and 50% rice husk charcoal : 50% soil) at 52 days after planting (DAP) produced the highest number of leaves, totaling 26. However, this increase in leaf number was not accompanied by an increase in fruit weight or brix levels. These findings open opportunities for further research to understand why the increase in leaf number did not translate to higher fruit weight or Brix levels, and to identify treatment combinations that can enhance both growth and yield.

Combination of thidiazuron and basal media type on optimizing in vitro growth of Grammatophyllum stapeliiflorum orchids
type: item
description: Grammatophyllum stapeliiflorum, recognized as the melancholic orchid, represents one of the elusive orchid species facing the brink of extinction, thus exacerbating its rarity. Tissue culture technology becomes imperative for the propagation of this orchid species. This study aims to scrutinize the influence of different concentrations of the synthetic growth regulator thidiazuron (TDZ) on distinct basal media types, Murashige Skoog (MS) and Vacin and Went (VW), on the in vitro growth of G. stapeliiflorum orchids. Employing a complete randomized factorial design, the study entails two research factors: TDZ concentration with 4 treatment levels, A0 = 0 mg/L, A1 = 0.25 mg/L, A2 = 0.50 mg/L, and A3 = 0.75 mg/L, and the second factor being the media type, B1 = ½ MS and B2 = ½ VW. Findings indicate significant effects of MS and VW media on the percentage of viable explants, browning, globular forms, and shoots. Interaction between TDZ concentration and media type didn't yield significant effects on each experimental parameter. Treatment with 0.25 and 0.50 mg/L TDZ on ½ VW media demonstrated optimal results for explant growth percentage, browning, and explants in the globular phase, at 97.33%, 2.67%, and 2.67%, respectively. Moreover, treatment with 0.75 mg/L TDZ on ½ VW media resulted in the highest percentage of explant coloration. The combination of TDZ and media has shown the potential to enhance the production efficiency and conservation of this rare orchid species through tissue culture technology.
