Abstract

Sago is one of the strategic local food commodities in Indonesia that has great potential in supporting food diversification, especially in Merauke Regency. This study aims to find out the trading system of sago management in Merauke Regency. The method used in this study is a descriptive method with qualitative and quantitative approaches. The qualitative approach is used to describe the sago trading system, the pattern of relationships between business actors, the production process, processing, distribution, and the institutional roles involved. The results of the study show that the sago management business system in Merauke Regency is still dominated by the traditional system with indigenous peoples as the main producers, while distribution and marketing are centered on the local market. Sago processing began to develop from traditional to semi-modern methods so as to increase the efficiency, quality, and selling value of products. Sago has great economic potential as a source of local food and industrial raw materials, but its development still faces technological constraints, market access, capital, unstable prices, and land conversion. Therefore, government support, technological innovation, and strengthening of MSMEs are needed so that sago can become a leading commodity that supports food security and the welfare of the people of Merauke

Abstract

The objective of this study was to analyze insect diversity and community structure in rice plants across three ecosystem types: rice fields bordering forests, swamps, and settlements. The study was conducted from April to July 2025 in Tanah Miring District, Merauke Regency, South Papua Province. At each location, five observation plots measuring 5 × 5 m² were established. Sampling was carried out using the sweep net method during the vegetative and generative growth stages of rice. Data were analyzed using the Shannon–Wiener diversity index (H’), evenness index (E), and dominance index (C). The results showed that insect communities were dominated by pest groups across all ecosystem types. Rice fields bordering forests exhibited the highest insect abundance and natural enemy populations, while swamp-adjacent ecosystems showed lower abundance but more even distribution of individuals, indicating relatively stable community conditions. In contrast, ecosystems bordering settlements were strongly dominated by pests, particularly the family Cicadellidae, reflecting ecological imbalance due to environmental pressure, agricultural intensification, and pesticide use. The diversity index was moderate (H’ = 1.98–2.41), evenness was high (E = 0.73–0.91), and dominance was low to moderate (C = 0.14–0.24), indicating relatively stable community conditions.Varietal differences revealed that Cigelis and Agritan tended to have higher pest populations, whereas Inpari 32 and Inpari 42 exhibited a more balanced community structure. Landscape factors play a crucial role in shaping insect communities; therefore, ecologically based integrated pest management is essential to maintain the sustainability of rice agroecosystems.
