This research addresses the pressing issue of the medicinal utilization of selected forest plants in the Ifo Local Government Area of Ogun State, Nigeria. Commencing with a succinct presentation of the identified problem, the study aims to explore solutions to formulated research questions and test hypotheses at a significance level of 0.05 alpha. Employing a descriptive survey research design, the study involves one hundred respondents randomly selected from Ifo Local Government Area. Five communities, i.e., Alagbole, Lambe, Ibogun, Onihale, and Igbusi, were purposively sampled, with 20 randomly chosen respondents. Data collection utilized a self-structured questionnaire to gather pertinent responses on the variables central to the study. Analysis methods included simple percentages, tables, Pearson Product-Moment Correlation Coefficient (PPMCC), and independent Student's T-test statistic. The research findings highlight, among other insights, the frequent use of forest plant-derived herbs for treating or preventing various health issues in the study area. As a recommendation, the study suggests the need for effective legislation to regulate the harvesting and trade of medicinal plants.</p> 2024-03-31T08:05:59+00:00 Copyright (c) 2024 Jurnal Ilmiah Pertanian Updates on hosts and distribution of pepper yellow leaf curl Indonesia virus and squash leaf curl China virus in Central Java Province, Indonesia 2024-03-31T09:56:21+00:00 Adyatma Irawan Santosa [email protected] Adenisa Hanifah Irbati [email protected] Geby Nandita Cahyaning Pratiwi [email protected] Antama Surwadinata [email protected] Putri Laeshita [email protected] Krisnanda Surya Dharma [email protected] Reko Saputra Jaya [email protected] Annisa Lisa Andriyani [email protected] Chilya Qurrota A'yun [email protected] Chusnu Naura Syifa Fatika [email protected] <p>Chili pepper, tomato, and squash&nbsp; cultivated in Magelang Regency, Central Java Province, Indonesia showed severe viral symptoms. Three samples were taken then molecularly tested against begomovirus, potyvirus, tobamovirus, and polerovirus. However, PCR test confirmed only begomovirus infections. BLAST analysis concluded that the chili pepper and tomato isolates were pepper yellow leaf curl Indonesia virus (PepYLCIV) while the squash isolate was squash leaf curl China virus (SLCCNV). The 552 bp partial AV1 gene sequences of the three isolates were given NCBI GenBank acc nos. OR924278-80. PepYLCIV OR924279 and OR924280 formed a subgroup with LC542629 from Bali in the phylogenetic tree constructed using MEGA11, and shared 95.8 – 96.7% identities at nucleotide (nt) and 98.4 – 99.5% at amino acid (aa) levels according to Sequence Demarcation Tool v1.2 software. Meanwhile, SLCCNV OR924278 was clustered, and shared 95.8 – 96.7% nt and 98.4 – 99.5% aa identities with three Malaysian isolates (MW248685, MW248687, and MW248689). Different plant species inoculated with SLCCNV OR924278 remained symptomless up to four weeks observation, suggesting that the isolate is not mechanically transmissible. This study contributed additional knowledge on molecular variation while expanding hosts and distribution of PepYLCIV and SLCCNV in Central Java Province.</p> 2024-03-14T00:00:00+00:00 Copyright (c) 2024 Jurnal Ilmiah Pertanian Combination of thidiazuron and basal media type on optimizing in vitro growth of Grammatophyllum stapeliiflorum orchids 2024-06-03T23:24:55+00:00 Yuniati [email protected] Mayta Novaliza Isda [email protected] <p><em>Grammatophyllum stapeliiflorum</em>, 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 <em>thidiazuron </em>(TDZ) on distinct basal media types, Murashige Skoog (MS) and Vacin and Went (VW), on the in vitro growth of <em>G. stapeliiflorum</em> 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.</p> 2024-03-30T00:00:00+00:00 Copyright (c) 2024 Jurnal Ilmiah Pertanian Landslide hazard assessment and agricultural vulnerability using a geospatial approach 2024-03-31T11:15:02+00:00 Rian Gabriel Girsang [email protected] Bistok Hasiholan Simanjuntak [email protected] <p>The village of Cukilan, Semarang Regency, Indonesia, is predominantly utilized for agricultural purposes, facilitated by its high rainfall suitable for various crops. Despite the benefits it provides to farmers, the elevated rainfall also poses natural disaster risks, particularly landslides, which can adversely affect surrounding communities. This study aims to map landslide potentials and evaluate their impacts on the agricultural sector in the Cukilan Village, Semarang Regency. The research methodology encompasses a literature review focusing on landslide potential estimation and field survey. The literature review aims to obtain landslide potential distribution maps compiled by DVMBG, considering rainfall, slope, geology, land use, and soil types. Field surveys validate conditions based on landslide potential estimations, involving random soil sampling and analyzing parameters like permeability, texture, bulk density, depth, and surface density. The research findings reveal the impact of landslide potential on the agricultural sector and the mapping of landslide potential areas in Cukilan Village, depicting various risk levels: very high (0.71% of total area, covering 5 ha), high (13.24%, 93 ha), moderate (56.55%, 397 ha), and low (29.48%, 207 ha). Based on these findings, it is evident that managing landslide disaster risks in agricultural development in the area is crucial, including the implementation of safer land use planning and appropriate mitigation strategies.</p> 2024-03-30T00:00:00+00:00 Copyright (c) 2024 Jurnal Ilmiah Pertanian Characterization of composting process and chemical composition of compost from recycling centers in Surabaya City, Indonesia 2024-03-31T15:15:15+00:00 Dwi Haryanta [email protected] Tatuk Tojibatus Sa’adah [email protected] Indarwati [email protected] <p>Composting serves as a pivotal strategy in waste management, alleviating the burden on final disposal sites while simultaneously providing valuable fertilizer for urban agriculture. This study aims to delineate the intricacies of the composting process and elucidate the characteristics of compost derived from recycling centers/compost houses in Surabaya City, Indonesia. Employing a qualitative descriptive approach, this research scrutinized the composting process by delving into the origins of raw materials, procedural stages, and the chemical composition of the resultant compost. The composting materials encompassed household waste, market refuse, and fall foliage. Notably, composting occurred within an open aerobic system devoid of bio-activators. Chemical analysis revealed: C/N ratio (17.10 - 19.60), C-total (17.65% - 18.10%), N-total (0.95% - 1.12%), P<sub>2</sub>O<sub>5</sub> (0.35% - 0.51%), K<sub>2</sub>O (0.39% - 0.41%), Cu (1.65 ppm - 2.01 ppm), Pb (2.05 ppm - 3.11 ppm), Cd (0.11 ppm - 0.24 ppm), and Zn (1.02 ppm - 1.14 ppm). Physically, the compost manifested as a dark brown substance, exhibiting a soil-like softness attributable to grinding, with temperatures oscillating between 41.90 to 55.00°C. Visually, the compost appeared mature and primed for utilization based on color and texture criteria; however, indicators such as C/N ratio and temperature suggest an immature state rendering the compost unsuitable for immediate planting. To ensure optimal maturity conducive to plant growth, it is recommended that users store the compost for a minimum of one month before application, thereby fostering its maturation process.</p> 2024-03-30T00:00:00+00:00 Copyright (c) 2024 Jurnal Ilmiah Pertanian
