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

Insect pollinators are insects that play an important role in maintaining the existence of a plant species through pollination and maintaining the genetic diversity of plants in the population maintaining the existence of a plant species through pollination and maintaining the genetic diversity of plants in the population. Pollinator insects generally come from the Hymenoptera order. The purpose of this study was to determine the types of pollinator insect species that dominate coconut plantations in the Banyuasin area of South Sumatra. Data were collected by field observation using the plant survey method. The survey was conducted through direct observation of coconut plants owned by coconut farmers in the Banyuasin area. Observations were made on coconut plants by observing pollinator insect species that associate with flowers on coconut plants. Insect pollinator species found in coconut plantations in the Banyuasin area include Vespa affilish, Apis mellifera, and Apis dorsata. The most dominant type of pollinator insect found in coconut plantations in the Banyuasin area is Apis dorsata with 201 individuals. So, the results show that the abundance of individuals is high but has a low diversity index.

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

Abstrak: Gulma sering dianggap sebagai tanaman pengganggu yang menurunkan produktivitas, namun gulma mengandung senyawa bioaktif seperti alkaloid, flavonoid, terpenoid, saponin, dan lainnya yang berpotensi dijadikan pestisida dan pupuk organik. Tujuan kegiatan pengabdian masyarakat ini adalah memberikan edukasi kepada petani di Desa Tanjung Dayang Utara, Sumatera Selatan, mengenai pemanfaatan gulma sebagai bahan dasar pestisida dan pupuk nabati yang ramah lingkungan serta berbiaya rendah. Metode pelaksanaan meliputi tahapan sosialisasi, penyuluhan, demonstrasi, pendampingan, dan evaluasi. Sebanyak 50 petani dan tokoh masyarakat mengikuti pelatihan pembuatan pestisida gulma dengan dua metode: sederhana dan ekstraksi. Evaluasi dilakukan secara berjenjang melalui diskusi pra-penyuluhan, uji praktek saat penyuluhan, dan pengamatan pertumbuhan tanaman. Hasil menunjukkan adanya peningkatan softskill peserta dalam pengolahan gulma hingga 75%, serta penurunan biaya pembelian pestisida dan pupuk sintetis hingga 40%. Kegiatan ini juga meningkatkan kesadaran petani terhadap praktek pertanian berkelanjutan dan penggunaan sumber daya lokal. Diharapkan ilmu yang diperoleh dapat ditransfer ke petani lain sehingga berdampak lebih luas dalam mendorong kemandirian dan efisiensi usaha tani.Abstract: Weeds are often seen as nuisance plants that reduce crop productivity. However, they contain bioactive compounds such as alkaloids, flavonoids, terpenoids, and saponins, which can be utilized as natural pesticides and organic fertilizers. This community service activity aimed to educate Tanjung Dayang Utara Village, South Sumatra farmers on using weeds as eco-friendly and low-cost agricultural inputs. The program involved socialization, counseling, presentations, mentoring, and evaluation. Fifty farmers and community leaders took part in training on pesticide production using simple and extraction methods. Evaluation was conducted through pre-counselling discussions, practical sessions, and plant growth observation. The activity improved participants' skills in weed processing by up to 75% and reduced the cost of synthetic pesticide and fertilizer use by up to 40%. It also increased awareness of sustainable farming practices and encouraged the use of local natural resources. The knowledge gained is expected to be shared with other farmers, fostering a broader impact through improved self-reliance and farming efficiency.

Abstract. Anggraini E, Istiqomah H, Irsan C, Herlinda S, Muslim A, Suwandi S. 2025. Comparative biology of bagworm larvae (Metisa plana) fed on oil palm (Elaeis guineensis) and malabar melastome (Melastoma malabathricum). Asian J Agric 9: 472-481. Metisa plana Walker, 1883 (Lepidoptera: Psychidae) is a significant defoliator in oil palm plantations, and the weed Melastoma malabathricum L. (malabar melastome) is believed to act as an alternative host, potentially maintaining pest numbers. This study assessed the comparative biology of M. plana larvae raised individually on oil palm and malabar melastome leaves in a laboratory setting. Recently emerged larvae (n?=?10 per treatment) were observed for leaf area consumption, larval bag form, developmental time, and survival rates. The results indicated that larvae consuming malabar melastome had a substantially greater leaf area consumption during instars 1-3 (up to 11.44?±?0.96?cm²) compared to those fed on oil palm (8.91?±?0.58?cm²; p?<?0.05), with the differences becoming non-significant from the 4th instar forward. The total duration of larval development was roughly 109 days on Malabar melastome and 103 days on oil palm, with no statistically significant difference (p > 0.05), while survival rates above 80% on both hosts. The length of larval bags exhibited substantial variation in the early instars (p < 0.01), but remained comparable in subsequent stages, and pupal weight was not assessed. The findings affirm that M. malabathricum serves as an appropriate alternate host for M. plana, underscoring the necessity for integrated weed management to avert malabar melastome from functioning as a reservoir, thereby enhancing the efficacy of pest management measures in oil palm ecosystems.
