Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The Duku plant (Lansium domesticum) is one of the popular tropical fruit in indonesia. Using the idea of plant cells' totipotency, tissue culture is an alternate method for a quick and massive propagation of high-quality duku plant seedlings. This research was aimed to evaluate different sterilization materials and procedures on duku leaf midrib explants through tissue culture. The research was conducted from June to September 2024 at Tissue Culture Laboratory, Department  of  Agronomy, Universitas Sriwijaya (2°59’23.4”S 104°43’53.4”E). A combination of  sterilizing substances, including 70% alcohol, fungicide, bactericide, liquid detergent, and NaOCl, were utilized in this sterilization procedures. The percentage of live explants, browning explants, and explants infected with bacteria or fungi then were calculated using parametric descriptive analysis. The results showed that the P3 treatment's sterilant combination liquid detergent for 3 minutes, 0.2% of fungicide and bactericide for 10 minutes, 1% NaOCl for 15 minutes, and 70% alcohol for 5 minute produced the highest percentage of live explants (46%) with a relatively low percentage of contaminated explants (30%) and the lowest percentage of browning explants (23%). Thus P3 treatment was concluded as the best treatment to reduce the contamination level and browning of duku leaf midrib explant.

Abstract

[ARTHROPOD DIVERSITY IN RED CHILI CULTIVATION UNDER SUGAR PALM SHADE IN SOUTH SUMATRA]. Arthropods are essential components of terrestrial ecosystems, functioning as pollinators, decomposers, herbivores, and natural enemies, and their presence reflects the health of agricultural landscapes. The red chili agroforestry system under sugar palm shading in South Sumatra creates a favorable habitat for arthropod communities through the interaction of canopy cover, microclimate conditions, and plant diversity. This study aimed to analyze the structure, diversity, and ecological roles of arthropod communities associated with chili plants withinthis system. Sampling was conducted systematically across several plots, and collected specimens were identified and analyzed using the Shannon–Wiener diversity index, evenness, and dominance metrics. The results showed that the arthropod community consisted of various orders, with predators forming the dominant guild, followed by pollinators, herbivores, and decomposers. The balanced distribution of individuals among trophic groups indicates a stable community structure, while fluctuations in population density were associated with plant growth stages and seasonal variation. The agroforestry environment of chili plants shaded by sugar palms supports a functionally diverse arthropod community that contributes to maintaining biodiversity and enhancing natural pest regulation. Arthropods in shaded cultivation also experience a more stable microhabitat than those in open fields, allowing for stronger interspecific interactions, including predator–prey dynamics that aid in natural pest suppression. Sustained diversity suggests that agroforestry systems reduce environmental stress on arthropod populations, helping communities function effectively. Therefore, the findings of this study provide an important scientific foundation for developing sustainable agroforestry management strategies that improve ecosystem services and support resilient agricultural production.

Abstract

Natural controls, such as predators and parasitoids, play a crucial role in maintaining the stability of agricultural ecosystems through biological pest control mechanisms. On the rice agriculture systems, we propose to evaluate the diversity and abundance of natural controls in organic and conventional rice cultivation systems in Tegal Sari Village, Ogan Komering Ulu Timur Regency, South Sumatra. Observations were conducted using a systematic survey method employing various types of insect traps, with organism identification carried out to the level of type. This research is expected to contribute to both academic and practical domains. The results revealed the presence of 10 arthropod species from four orders, including Araneae, with dominant species such as Pardosa pseudoannulata, Tetragnatha extensa, Tetragnatha montana, Tetragnatha sp., Tigrosa annexa, and Zygiella are always higher on the organic rice agricultural system compared to the conventional system. The diversity analysis indicated that sweep nets were more effective in capturing natural controls compared to other traps, with a Shannon-Wiener diversity index value of 2.17, suggesting moderate diversity. These findings emphasize that organic farming supports biodiversity conservation and provides a scientific foundation for the development of pest management strategies.

Abstract

The management of organic waste presents a significant challenge in Indonesia, especially fruit and vegetable by-products. Black Soldier Fly (BSF, Hermetia illucens) larvae offer an effective solution due to their high potential for organic waste conversion. This study investigated the efficacy of BSF larvae in reducing and bioconverting organic waste composed of banana peels and sprout hulls, and examined the influence of EM4 fermentation on larval growth performance. Waste Reduction Index (WRI) and bioconversion rate (BCR) were calculated as percentages and analyzed descriptively, followed by the Kruskal–Wallis test. Furthermore, larval length and body weight were measured at 7, 11, 14, and 18 days of larval age and analyzed using Kruskal–Wallis with Dunn’s post-hoc test. The results showed that EM4–fermented substrates containing a 1:3 ratio of banana peels to sprout hulls showed the highest waste reduction and bioconversion potential among all mixture treatments (P < 0.05). Although larval length and weight were lower than control substrate, no significant difference in larval length was detected, while individual larval weight was significantly higher compared to other organic waste combinations (P < 0.001). In this study, EM4 fermentation enhanced lignocellulosic degradation, improving substrate digestibility for BSF larvae and optimizing bioconversion efficiency, thus supporting more sustainable organic waste management strategies.

Abstract

Lansium domesticum Corr. is a fruit crop with high consumer demand; however, its conventional propagation is relatively slow. In vitro culture offers a potential alternative to accelerate plant propagation. This study aimed to evaluate sodium hypochlorite (NaOCl)-based sterilization protocols and identify the most effective treatment for in vitro establishment of leaf lamina explants. The experiment was conducted at the Tissue Culture Laboratory, Faculty of Agriculture, Universitas Sriwijaya, from July to September 2024 using five sterilization treatments with different NaOCl concentrations and exposure times. Data were analyzed descriptively to determine the percentages of bacterial contamination, fungal contamination, surviving explants, and browning incidence. The results showed that the treatment consisting of liquid detergent (3 min), 0.2% streptomycin sulfate (10 min), 0.2% benomyl (10 min), 1% NaOCl (15 min), and 70% ethanol (5 min) was the most effective protocol. This treatment resulted in 63% explant survival, 0% browning, 33% bacterial contamination, and 3% fungal contamination. This study provides a practical sterilization protocol that balances antimicrobial effectiveness and tissue viability, representing a novel contribution for in vitro propagation of Lansium domesticum. The findings have important implications for improving large-scale propagation efficiency of this economically important tropical fruit species. These results indicate that moderate NaOCl exposure is essential to achieve an optimal balance between contamination control and explant viability in in vitro culture systems.

Abstract

Plant health problems caused by pests and diseases remain a significant challenge for farmers, especially in cultivating red curly chili and cayenne pepper. Conventional reliance on synthetic pesticides raises environmental and economic concerns. This community service program aimed to enhance farmers' knowledge in using biological agents as alternatives to synthetic pesticides to strengthen plant resistance. The program was carried out in Tanjung Dayang Utara Village, Ogan Ilir, through stages of preparation, implementation, evaluation, mentoring, and monitoring. Methods included lectures and demonstrations on using Pseudomonas fluorescens and Trichoderma sp. through seed soaking and soil or foliar application. A total of 50 farmers attended, receiving both theoretical and practical training. The evaluation was conducted in three phases: pre-, during, and post-activity. Previous approaches relied heavily on synthetic pesticides, while recent innovations emphasize ecological pest management using microbial antagonists. The outcomes showed a high level of enthusiasm and improved understanding among farmers regarding natural pest resistance mechanisms. Farmers were able to practice the propagation and application of beneficial microbes supported by educational materials. The program reduced farmers' dependency on chemical inputs and contributed to sustainable agricultural practices. This model using replicable in similar agroecosystems facing pest and disease issues. The main problem addressed was farmers’ limited knowledge and skills in utilizing biological control agents as environmentally friendly alternatives. The implementation consisted of preparation, training through lectures and demonstrations, field practice, and evaluation. The results indicated measurable improvements, including increased knowledge based on evaluation scores and reduced reliance on chemical pesticides
