A significant pest affecting oil palm cultivation, especially during replanting, is the rhinoceros beetle (<em>Oryctes rhinoceros</em> L.). Attractant pheromones, derived from pineapples, contain volatile compounds that attract insects. This research aims to develop an automated rhinoceros beetle trap equipped with an automatic pheromone spray system utilizing natural peel pineapple extract. The analysis includes tests for fluid density, spray distribution, and normality. The fluid density of the sample closely resembles that of water (1 g/cm³). Spray distribution results indicate particle sizes (60-112 μm) larger than airborne aerosols (0.001-50 μm). Kolmogorov-Smirnov normality tests reveal mostly normal data distribution, with minor deviations. Overall, this trap exhibits promise as an effective solution for rhinoceros beetle control in oil palm cultivation.</p> Lailatul Munawaroh Shabri Putra Wirman Neneng Fitrya Romi Fadli Syahputra Novia Gesriantuti Copyright (c) 2023 Jurnal Ilmiah Pertanian https://creativecommons.org/licenses/by/4.0/ 2023-12-19 2023-12-19 20 3 200 208 10.31849/jip.v20i3.15857 In vitro shoot induction from petiole explants of tembesu (Fagraea fragrans Roxb) using 6-benzylaminopurine https://journal.unilak.ac.id/index.php/jip/article/view/11772 <p>Tembesu (<em>Fagraea fragrans</em> Roxb) is a valuable woody plant from the Loganiaceae family, utilized in construction and furniture production. Unfortunately, the tembesu population continues to decline due to excessive logging, forest fires, and a lack of cultivation efforts. Planting through seeds takes a long time, making in vitro propagation an attractive alternative. This research aims to evaluate the effect of 6-benzylaminopurine (BAP) in inducing shoots and determine the optimal BAP concentration on tembesu petiole explants in vitro. A completely randomized design (CRD) with six treatment levels (0, 0.5, 1, 1.5, 2, and 2.5 mg/L BAP) and five replications was employed. Despite a 10% shoot formation rate for each treatment, the optimal BAP concentration for callus formation was found to be 0.5 mg/L, with the highest percentage reaching 70%. The results indicate that adding different concentrations of BAP to the Murashige &amp; Skoog (MS) medium was ineffective in inducing shoots in tembesu petiole explants. Therefore, further research and the development of more sophisticated in vitro propagation techniques are necessary to enhance the success of shoot induction in tembesu. It is hoped that this research will serve as a foundation and motivation for subsequent in-depth studies on the in vitro propagation of tembesu, supporting the conservation and development of this plant.</p> Mayta Novaliza Isda Riche Afrilla Copyright (c) 2023 Jurnal Ilmiah Pertanian https://creativecommons.org/licenses/by/4.0/ 2023-12-24 2023-12-24 20 3 209 218 10.31849/jip.v20i3.11772 A comparative study on pesticide residue profiles in locally grown rice from conventional and sustainable agricultural methods https://journal.unilak.ac.id/index.php/jip/article/view/17122 <p>Amid escalating concerns about pesticide residues in agricultural product, this study conducts a meticulous comparative analysis of pesticide residue profiles in locally grown rice, aiming to contribute essential insights for informed decision-making in agriculture. The overarching problem addressed involves identifying pesticides in rice from conventional and sustainable farming and understanding their potential environmental and health implications on food safety. Utilizing HPLC/MS-MS, the research discerns a notable absence of over 500 pesticide types in rice cultivated according to good agricultural practices (GAP). Conversely, rice from fields deviating from GAP guidelines reveals the presence of 7 pesticide active ingredients, with 2 exceeding globally established residue limits by twice the recommended amount. Notably, bifenthrin and tebuconazole, uncommonly used in the last one years, are identified. This study underscores the urgency of adhering to sustainable agricultural practices for the safety and quality of rice, offering critical insights for future research. It not only contributes to current knowledge but also emphasizes the global necessity of safe agricultural practices to safeguard our food supply.</p> Indra Purnama Farag M.

Control measures using synthetic pesticides have been implemented but yielded unsatisfactory results. The utilization of resistant varieties stands as a pertinent approach in early control efforts to minimize harvest losses. Additionally, the use of resistant varieties is a crucial component of integrated disease control implementation. This study aims to investigate the resistance levels of ten chili varieties commonly grown in swampy areas against specific isolates of <em>Colletotrichum </em>sp. present in swampy locations. The research, conducted in a randomized complete design in a greenhouse, tested ten varieties of cayenne pepper typically cultivated in swampy areas. The results revealed that the Hiyung variety is Susceptible, while Bara, Dewata 43 F1, Tiung Tanjung, Genie, Sekar, and CR-9 varieties exhibit moderate resistance. Conversely, Tiung Ulin, Alip, and Sret varieties are classified as resistant. The incubation period for tested cayenne pepper varieties varied, ranging from 3.5 to 5.3 days. A longer incubation period indicates greater resistance to anthracnose in chili varieties. The selection of resistant varieties is a pivotal step in anthracnose management, not only to minimize harvest losses but also to support an effective integrated control approach.</p> Ismed Setya Budi Mariana Mariana Amalia Fauziah Copyright (c) 2023 Jurnal Ilmiah Pertanian https://creativecommons.org/licenses/by/4.0/ 2023-12-26 2023-12-26 20 3 232 246 10.31849/jip.v20i3.16042 Boosting strawberry yield and fruit sweetness with humic substances and biofertilizer in soilless cocopeat-based culture https://journal.unilak.ac.id/index.php/jip/article/view/13242 <p>Farmers usually apply more chemical fertilizers to enhance the yield of strawberries in soilless culture. Humic substances and biofertilizers are now considered essential nutrient sources in sustainable agriculture. The objective of the greenhouse experiment was to observe the effect of humic and fulvic acid (humic substances), and biofertilizer on root growth, nitrogen (N) and phosphor (P) of the growing media, populations of N-fixing and P-solubilizing bacteria in the root zone, and yield of strawberry grown in the cocopeat-based substrate. The experiment was set up in a randomized block design consisting of seven treatments and four replications. The treatments included humic acid, fulvic acid, and biofertilizer in single or combined applications. All data were subjected to analysis of variance and followed by Duncan's Multiple Range Test with p&lt;0.05. All treatments received 50% of the recommended dose of NPK fertilizer. The results showed that all treatments did not affect root length and dry weight. Mixed application of humic substances and biofertilizer together with NPK fertilizer increased total N and P as well as the population of N-fixing bacteria in the growth substrate. Still, P-solubilizing bacteria did not grow in the cocopeat-based substrate. Moreover, mixing humic substances and biofertilizer increased strawberries' fruit yield and sweetness levels.</p> Reginawanti Hindersah Ratna Ayu Permata Aini Mieke Rochimi Setiawati Tualar Simarmata Diky Indrawibawa Masako Akutsu Copyright (c) 2023 Jurnal Ilmiah Pertanian https://creativecommons.org/licenses/by/4.0 2023-08-05 2023-08-05 20 3 247 257 10.31849/jip.v20i3.13242 Optimal growth conditions for avocado (Persea americana Mill.) seedlings using biofertilizer-based approach with biosurfactant diethanolamide palm olein and neem extract https://journal.unilak.ac.id/index.php/jip/article/view/16276 <p>Avocado is a much-loved fruit with high nutritional content. However, its current production has declined due to excessive and continuous use of chemical fertilizers. Biofertilizers can be applied to reduce the reliance on chemical fertilizers, promoting soil health and fertility by providing essential macro and micronutrients for better plant growth. This study aimed to determine the optimal dosage and method for the combined application of biofertilizer, biosurfactant diethanolamide (DEA) palm olein, and neem extract on avocado seedlings. The experimental design used was a factorial randomized complete block design with two factors. The first factor was the biofertilizer dosage (B) and the second factor was the application method (M). Results indicate that a 10 mL/L biofertilizer dosage, 5% DEA, and 35% neem extract show the best effects on plant height, leaf chlorophyll levels, stem diameter, and the number of avocado leaves. The application method of applying to the planting medium yields the best results for plant height, leaf count, and leaf chlorophyll levels. There was an interaction between treatments regarding plant height at 10 weeks after transplanting (WAT) and leaf count at 8 WAT. Biofertilizer application by pouring is recommended as an alternative to inorganic fertilizers for promoting healthy avocado seedling&nbsp;growth.</p> Muhamad Sopian Nurmayulis Abdul H.

Chinensis) nutrient content: investigating the effects of chicken manure compost and bioactivator combinations on various doses https://journal.unilak.ac.id/index.php/jip/article/view/12176 <p>Chicken manure compost serves as a valuable source of organic fertilizer. This study aimed to investigate the effects of different combinations of chicken manure compost and bioactivators on soil and plant nutrient content. Additionally, it sought to examine the relationship between fertilizer dosage and soil and plant nutrient levels, as well as determine the optimal treatment combination of chicken manure compost and bioactivator variations at different doses. In this study, the plant used was pakcoy. The study utilized a randomized group design with two factors. The first factor involved different compost types: A1 (chicken manure compost), A2 (chicken manure compost + N21 bioactivator), and A3 (chicken manure compost + local microorganism (MOL) solutions from banana weevil). The second factor encompassed varying doses of organic fertilizer, 5, 10, 15, and 20 tons ha<sup>-1</sup>, respectively for D1-D4. The findings revealed that composting chicken manure with different bioactivators and doses led to increased soil nutrient levels and noticeable effects on plant nutrient content. However, no interaction was observed among the combined treatments. The treatment combination of chicken manure compost and MOL solutions from banana weevil yielded the highest average plant nutrient content. Applying chicken manure compost with different bioactivators and doses influenced soil nutrient levels.</p> Trisia Wulantika Yun Sondang Rina Alfina Ngakumalem Sembiring Sentot Wahono Wiwik Hardaningsih Yefriwati Ritawati Febria Fitri Copyright (c) 2023 Jurnal Ilmiah Pertanian https://creativecommons.org/licenses/by/4.0 2023-08-02 2023-08-02 20 3 271 280 10.31849/jip.v20i3.12176 Influence of green manure (Leucaena leucocephala) dosages on eggplant (Solanum melongena) growth and yield across diverse soil types https://journal.unilak.ac.id/index.php/jip/article/view/13547 <p>Eggplant cultivation displays versatility across various soil types. However, nutrient depletion, a result of excessive chemical fertilizer utilization, presents a growing concern. The integration of green manure into agricultural practices, catering to diverse soil types, can remediate this nutrient loss. The purpose of this study was to investigate eggplant growth and yield responses to differing green manure quantities across varying soil types. Employing a factorial experimental method, this research was structured in a completely randomized design (CRD). Two independent variables were evaluated: green manure dosage, with three levels (30 g/plant (D1), 60 g/plant (D2), 90 g/plant (D3)), and soil type, also classified into three categories: Latosol (T1), Grumusol (T2), and Regosol (T3). Data interpretation was conducted using analysis of variance, followed by the Tukey test, each executed at α = 5% significance level. Outcomes indicated a notable interaction between green manure dosage and soil type concerning the leaf area and root fresh weight parameters. The optimal combination emerged as a 30 g/plant green manure dosage applied to Regosol soil type. Notably, individual treatments exerted divergent effects on eggplant growth parameters, though no significant impact on eggplant yield parameters was observed. This research underscores the interplay between green manure usage and soil type in cultivating eggplants, adding value to sustainable agricultural practices.</p> <p>&nbsp;</p> Anggit Kurniawan Titin Setyorini Valensi Kautsar Copyright (c) 2023 Jurnal Ilmiah Pertanian https://creativecommons.org/licenses/by/4.0 2023-08-04 2023-08-04 20 3 281 291 10.31849/jip.v20i3.13547
