Abstract

Polyculture farming is an agricultural practice of growing several types of crops on the same land.The sustainability of polyculture farming is influenced by the presence of insects, both ecologically beneficial and detrimental. In agricultural ecology, insects have an important role as pollinators, predators, and pests that significantly affect the health of agricultural crops, including in polyculture farms. As an effort for sustainable polyculture management, especially in pest control, an exploratory study with mixed methods was conducted to determine the diversity, distribution, and categories of insects based on their ecological roles. This study was conducted in an agricultural area with a polyculture system in Palangka Raya, Central Kalimantan, Indonesia. A total of 12 insect species were identified from polyculture farms belonging to the orders Coleoptera, Diptera, Hemiptera, Lepidoptera, and Hymenoptera. The diversity of insects found in polyculture farming in this study was categorized into low diversity with a Shannon-Wiener index (H') of 2.186. Hemiptera is known to be the most abundant with 7 species identified. Based on the number of individuals, Componotus japonicus is the most abundant species with 9 individuals. The structure of the insect community based on their ecological role in polyculture farming consisted of 58.33% insect pests, 33.33% predatory insects, and 8.33% pollinating insects.

Abstract

This community engagement program aimed to enhance the capacity of the Sangalang Hapakat Farmers Group in cultivating oyster mushrooms (Pleurotus ostreatus) by utilizing rice husk as an alternative substrate to sawdust. The activities included technical training, field practice, and the supervised production of baglogs using four media formulations. Rice husk was selected due to its local abundance in Pulang Pisau’s food estate area and its high fiber content which supports mycelium growth. Results indicated that formulas with higher rice husk content (K2 and K4) accelerated mycelium colonization (25 days), pinhead formation (30–35 days), and fruit body regeneration (5–8 days). While fresh weight per baglog (1–3 ounces) showed no significant difference, mushrooms appeared whiter. Five out of nine farmers committed to continuing mushroom production using rice husk media. This innovation promotes cost efficiency, agricultural waste reduction, and production sustainability, aligning with SDGs 1, 2, 8, and 12. The program successfully transferred appropriate technology, improved farmers' skills, and presents potential for wider replication.
