Abstract

Livestock waste becomes a problem and disturbs the community environment. In addition to the odor generated, it causes an unclean environment. Livestock waste is a problem for the people of Jungkal Village, Pampangan District, Ogan Komering Ilir Regency, South Sumatra. Good environmental management must be a priority. Therefore, livestock waste must be utilized to create a healthy environment. The purpose of this activity was to explain the use of livestock waste as a medium to produce bio-insecticides made from the active Bacillus thuringiensis bacteria. The target community was a farmer group in Jungkal Village. Activities were carried out in two ways, namely socialization activities and practical activities to produce bio-insecticide with active B. thuringiensis. Preliminary data showed that farmers were aware that livestock waste causes discomfort. Handling both liquid and solid waste has yielded little results because, so far, farmers have only gotten rid of this waste without using it as a helpful product. After the community service activities were completed, 80% of the participants understood the benefit of livestock waste. With an intensive approach and assistance, farmer groups can receive new directions.

Bintang, G. P., Herlin, W., Pakpahan, T., Zelianty, S. O., Arka, K., Aryanti, R.M., Indah, M., Jesika, J. (2024). Effectiveness of betel leaves (Piper betle) as a vegetable pesticide to suppress pests insect populations on cayenne pepper (Capsicum frutescens L.). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 90–102). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Cayenne pepper (Capsicum fructuscens L.) has a very high potential for cultivation, but the problem of cayenne pepper cultivation is never free from pest disease, so ethane used chemical pesticides because it is considered more effective and efficient. The purpose of this study was to find out the effectiveness of betel leaf weeds as botanical pesticides to suppressed pests in cayenne pepper. The methods used in this study are Group Randomization Design (GRD) with each group consisting of five treatments, namely P1 (control), P2 (50 gr/l), P3 (100 gr/l), P4 (150 gr/l), P5 (200 gr/) and six tests with a total of 30 cayenne pepper. The results of the studied on P5 (200 gr/l) had the highest insect diversity of 1.94, while P1 (control) had the lowest insect diversity of 1,10. The insect diversity found in the study based on observations from 1 to 80 Days After Planting consisted of 11 species covering several orders such as Lepidoptera, Diptera, Coleoptera, Aranae, Hemiptera, and Hymenoptera. The conclusion of this study is that the higher the dose of betel leaf pesticide used, the lower the attack of insect pests with species of aphids (Aphis gossypii), mealybugs (Pseudococcus sp.), flies (Sarcophaga sp.), caterpillars (Syrphidae sp. larvae), spiders (Araneus sp., Neoscona sp., Paidiscura sp., Oxyopes sp.), ants (Tapinoma sp.), ladybugs (Coccinellidae sp. pupa), and butterflies (Agraulis sp. larvae) on cayenne pepper. Thus, the use of botanical pesticides must be used with the appropriate dose in order to suppress the development of insect pest populations on cayenne pepper.

Abstract

Herlin, W., Fatkha, F. N., Zagar, Z., Destia, H., & Yuniva, E. A. (2024). Optimization of Babadotan weed (Ageratum conyzoides) as a vegetable pesticide on cayenne pepper plants (Capsicum frutescens L.) . In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang  21 Oktober 2024. (pp. 195–201).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Chili pepper plants (Capsicum frutescens L.) have high potential for cultivation. The density of pests that attack cultivated plants causes the pest population to swell. This study aimed to determine the effectiveness of babadotan weeds as botanical pesticides on chili pepper plants. The method used in this study was a Randomized Block Design (RAK), using 5 treatments, namely P0 (control), P1 (50 g / L), P2 (100 g / L), P3 (150 g / L), P4 (200 g / L) consisting of 6 replications with a total of 30 plants. The results of this study showed the growth of chili plants that were given botanical pesticides from several treatments carried out, namely plants that were not treated or not given pesticides were attacked more than chili plants that were given a lot of pesticides. In terms of plant height, the growth of chili plants that were given more botanical pesticides was higher than plants that were given less pesticides, in terms of the number of leaves, chili plants that were given more botanical pesticides had more leaves than chili plants that received less treatment. The conclusion of this study shows that botanical pesticides from babadotan weeds act as insecticides, repellents, binders, and pest growth inhibitors. Thus, it is necessary to use insecticides in the right dosage to control pest attacks on cayenne pepper.

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.
