Abstract. Mahmud, Endayani S, Stefano A, Lakehu A, Mutakim, Wahyudi, Husodo SB, Moeljono S. 2025. Shifting cultivation and soil conservation strategies among Papuan communities, Indonesia. Asian J Agric 9: 671-682. Local Papuan communities in Indonesia, rely heavily on land resources for food security, yet shifting cultivation remains the dominant practice. This system, while traditional, often leads to soil nutrient depletion, reduced productivity, and increased deforestation. To understand the dynamics of local farming practices, this study applied interviews, surveys, and participatory approaches with farmers and community members. Findings reveal that short-term crops such as long beans, peanuts, cabbage, chilies, and sweet potatoes dominate cultivation, contributing to rapid soil fertility loss. In contrast, perennial crops such as Areca catechu, Musa paradisiaca, Nephelium lappaceum, and Artocarpus altilis are typically maintained in fixed plots without being shifted. To address soil degradation, the study proposes several conservation strategies. These include mulching to retain soil moisture, living fences and cover crops to minimize erosion, intercropping to diversify yields and improve nutrient cycling, and the integration of Multipurpose Tree Species (MPTS) and hedgerows to restore long-term soil fertility. Collectively, these measures can reduce the necessity for continuous land clearing and help communities move toward more sustainable sedentary agricultural systems. Beyond technical solutions, the research highlights the importance of strengthening community awareness about forest and soil conservation. Transitioning away from shifting cultivation not only improves land productivity but also contributes to broader ecological resilience. By adopting integrated conservation practices, Papuan farmers can secure food production, maintain forest ecosystems, and develop more sustainable livelihoods in harmony with their environment.

Abstract. Moeljono S, Gunawan E, Husodo SB, Nugroho JD, Mofu WY, Tampang A, Beljai M, Sadsoeitoeboen BMG, Kesaulija FF, Mahmud, Iwanggin MP, Simbiak VI, Tasik S, Worabai MS, Padang DA, Yogaswara R. 2025. Analysis of sago starch (Metroxylon sagu) quality from various cultivars in the Yapen Islands, Papua, Indonesia. Biodiversitas 26: 2717-2725. Sago (Metroxylon sagu) is a palm plant that produces carbohydrates and possesses significant potential to support food security and industry in the Yapen Islands District, Papua. This study aimed to analyze the quality of sago starch from the various cultivars that thrive in the region. A quantitative method using a survey research design was applied, with sampling conducted in the Eastern and Western Yapen Sub-Clusters from January to March 2024. The physicochemical analysis of sago starch was carried out at the Forest Products Technology Laboratory of the University of Papua. The results indicate a diversity of sago cultivars in both areas, with the Woru and Noyn cultivars dominating Western Yapen, and Kurai and Amiri in Eastern Yapen. The starch yield varied significantly between cultivars, with the Noyn (630 kg/tree) and Huworu (264 kg/tree) cultivars recording the highest production. The physicochemical characteristics revealed a variation in moisture content (1.66-4.78%), fineness (88.98-95.12%), ash content (0.91-1.39%), and degree of acidity (1.3-5.7). The Kurai, Huworu, and Woru cultivars exhibited superior characteristics for food industry applications, while Makubong and Dami showed potential for non-food applications. The development of sago agro-business in the Yapen Islands District necessitates the selection of appropriate cultivars and the strengthening of post-harvest management systems to optimize both economic and ecological value.
