Abstract

Tujuan dari penelitian ini adalah untuk mempelajari efek limbah agroindustri dalam perbanyakan B. thuringiensis dan toksisitasnya terhadap larva O. rhinoceros. Penelitian dilakukan menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan dengan 4 kali ulangan meliputi : P1: (bekatul + bungkil kelapa sawit (2:1), P2: (bekatul + ampas tahu) (2:1), P3 (bekatul + bungkil kacang tanah) (2:1), P4 (bekatul + ampok jagung) (2:1), P5 (kontrol air) pada ruangan laboratorium (kisaran suhu 23,34oC-26,01oC dan kisaran kelembaban udara relatif 51,25% - 78,14%). Serangga uji berupa larva O. rhinoceros instar ke-3 sebanyak 6 ekor setiap ulangan. Tingkat mortalitas tertinggi (91,67%) tercatat pada perlakuan P1 (bekatul + bungkil kelapa sawit), sedangkan tingkat mortalitas terendah (66,67%) terjadi pada perlakuan P3 (bekatul + ampok jagung). Infeksi B. thuringiensis menyebabkan nafsu makan larva menurun dan mengakibatkan panjang dan berat tubuh larva mengalami penurunan selama pengamatan. Infeksi B. thuringiensis pada larva menyebabkan terjadinya perubahan warna pada tubuh dari putih menjadi kecoklatan hingga kehitaman dan akhirnya larva mati dalam keadaan tubuh melunak dan membusuk disertai cairan yang keluar dari tubuh larva. Secara keseluruhan hasil percobaan menunjukkan bahwa bioinsektisida berbahan aktif B. thuringiensis dengan media campuran limbah padat pertanian efektif untuk membunuh larva O. rhinoceros.

Abstract

Bitter melon plant (Momordica charantia L.) is a potential commercial plant if intensively cultivated in agribusiness, this plant can be very beneficial if it produces high levels of fruit production, it cannot be separated from insect pollination activities. Insects that visit bitter melon plant flowers are actually beneficial and can be harmful. This field practice aims to determine the relationship of visitor insects associated with bitter melon flowers (M. charantia L.), by using the scan sampling method (direct observation) in the field, which counts the number of species and individual insect’s visitors then will be identified in the Plant Pest Entomology Laboratory. Observations were carried out for 5 weeks. Every week took 2 days of observation, and in those 2 days there were observations on the same day and time which was on Tuesday and Thursday at 06:00: 30 - 08:30 AM (morning) and 04:00 - 05:30 PM (afternoon). What was observed s the insects who visited the bitter melon flowers of 6 orders including Hymenoptera, Coleoptera, Thysanoptera, Lepidoptera, Hemiptera, and Araneae as well as 8 families and 12 species of the orders. Insect visitors associated with bitter melon flowers have different roles including pollinators, predators, visitors and pests. The behavior also varies, especially in taking nectar or pollen as a source of nutrition.

Abstract

An experiment is conducted to investigate the effects of cultural techniques on pepper yellow leaf curl disease caused by Pepper yellow leaf curl Indonesia virus (PepYLCIV). The investigation is conducted in the area where the disease has been endemic and Bemisia tabaci is abundant. Four cultural techniques are applied in separate lands and cannot interfere with each other. The methods applied are seed treatment, intercropping, trap cropping, and physical barrier. Seeds harvested from infected plants are used for seed treatment experiments, and local farmers use commercial sources for other experiments. The results confirmed that PepYLCIV was a seed-borne virus affected by hot water treatment at 65oC for 30 minutes. Turmeric crude extract could reduce the incidence and severity of the disease. The tomato is a better intercrop than eggplant, mung bean, and soybean in reducing disease incidence, but their effects on disease severity and yield reduction were not significantly different. Basil and marigolds were better barrier crops compared to cosmos and zinnia. A 125 cm high physical barrier using 50 mesh cheesecloth could reduce the disease incidence, but not the lower ones. Under different cultural techniques, PepYLCIV causes a 40.00–52.32% chili yield reduction.

Abstract

Banana bunchy top disease has become increasingly important in South Sumatra. The disease, caused by Banana bunchy top virus (BBTV), leads to severe losses as infected plants fail to produce fruit. The virus is transmitted in a persistent manner by banana aphid, Pentalonia nigronervosa. Both nymphs and adults of the aphid can transmit the virus, with adults being more efficient vectors than nymphs. The threat of the disease in the province has been escalating, as indicated by the significant rise in the number of infected banana plants in the recent years. However, no epidemiological study had been conducted prior to this research. This study aimed to identify and evaluate the contributing factors to the epidemic of banana bunchy top disease in South Sumatra. A survey was conducted to assess the banana cropping system and all aspects contributing to the disease’s epidemiology in the province. Thirteen regencies were surveyed using a purposive sampling method, covering 11 regencies and 3 cities selected based on the accessibility of banana plantations by transportation routes. In each site, banana plants within an imaginary 50-meter diameter circle centered on an infected plant were sampled. The result showed that the BBTV epidemic was influenced by several factors: (1) banana genome, with diploid AA and triploid AAA cultivars being more resistant than those containing the B genome; (2) cropping system, with higher disease prevalence in mixed-cropping systems than in monoculture; (3) botanical environment, where the presence of alternative hosts of P. nigronervosa correlated with higher disease incidence; (4) farmer behavior, with lack of concern or action against the disease contributing to its spread; and (5) transportation access, with higher incidence observed in areas closer to roads.

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

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

Abstract

Integrated Pest Control in Chili Plantations with a Focus on Bioinsecticide Applications with Active Ingredients Bacillus thuringiensis. Bacillus thuringiensis is an entomopathogenic bacterium that plays important role in controlling plant pests. These bacteria can be propagated with agricultural waste media producing bioinsecticides. The use of bioinsecticides for controlling insect pests on chili plants was done through community service activities. The activity was carried out in Tanjung Baru Village, North Inderalaya Sub-district, Ogan Ilir Regency, South Sumatra, from August to October 2021. As one of the chili producing centers, farmers in Tanjung Baru Village grew chili almost all year round. Insects pests attacing chili plants were aphids, thrips, armyworms and fruit flies. Control is mostly done with synthetic insecticides, which are often mixed. Control activities focusing on the use of bioinsecticides with B. thuringiensis-based were carried out to overcome this problem. An initial demonstration plot was made for farmers to see the results of the experiment. The next stage farmers were given skills to make these bioinsecticides. To measure the success of the activity, a feedback survey was conducted amongfarmers. The survey results showed 80% of farmers were interested in using B. thuringiensis-based bioinsecticide and intended to use it. Regarding the skills of making bioinsecticides, more than 90% were interested in making their own, because waste materials as a medium for propagation were available in abundance. Chili farmers in Tanjung Baru Village can receive information from outsiders and showed a desire to change their old habit (use of chemical insecticides) to switch to biological control.
