Abstract

Tailing land reclamation aims to improve the environment so that the tailing areas become productive for crop cultivation. The research was carried out in the tailings area of Mile 21.5 Timika from March to September 2022. The research aimed to study the dosage levels of Pistia stratiotes composts as an ameliorant to support the growth and yield of chili cultivated in the fresh tailings area. This study was laid out in a randomized block design with the Pistia stratiotes compost as a treatment, which consisted of PS1 = 1 kg/plant, PS2 = 2 kg/plant, PS3 = 3 kg/plant, and PS4 = 4 kg/plant in 6 replications. Based on the results, there was a significant effect of Pistia stratiotes compost on the growth and yields of chili. PS4 treatment produced the highest growth (plant height and leaf number) and highest yields (fruit number/plant, fruit weight/plant, fruit weight/plot, fruit weight/ha), while PS1 produced the lowest growth and yields. Chili produced 4.19 t/ha by PS4, indicating a high yield potential when tailings turned into a more stable growth media over time. There was a significant correlation between plant height and leaf number with the fruit weight. This shows that the vegetative growth component is closely related to increased chili yields. The high heritability value indicates the genetic factor influenced the growth and yields of chili more than the environmental factors. The metal contents in the chili fruit tissue are below the threshold level. The findings of this study emphasized the appropriate reclamation approaches using Pistia stratiotes compost as an ameliorant, which effectively improves the quality of tailing as growing media to maximize chili yields.

Abstract

The mobile rice milling business has quite a significant potential because technology and science continue to develop, producing innovations to make human work more accessible. This research aims to analyze the feasibility of a mobile rice milling business in Prafi Mulya Village, Prafi District, Manokwari Regency. As a case study, the research method used is a quantitative descriptive method using tabulation and simple mathematics with mobile rice mill entrepreneurs in Prafi Mulya Village, Manokwari Regency. Data analysis uses Internal Rate of Return (IRR), Net Present Value (NPV), and RC-Ratio (RCR) analysis. The research results show that the mobile rice milling business has a minimum income of IDR 16,315,,667 and the maximum income is IDR 212,790,381 with an average income of IDR 66,323,683 per year. Furthermore, the average IRR value is 7%, and the average NPV value is IDR 894,170,337.00 and the average RCR value is 2.03. The mobile rice milling business in Prafi Mulya Village, Prafi District, Manokwari Regency, is included in the suitable business or running criteria. This is because the calculation results based on the NPV and RCR assessment criteria show that the rice milling business has met the business feasibility requirements. Still, based on the IRR, three respondents are in the no category because the IRR value is smaller than the discount rate.

Abstract

Rice farmers in Indonesia face significant challenges due to climate change, including unpredictable weather patterns, extended dry spells, and increased pest outbreaks. This study explores the resilience of rice farmers to climate change through sustainable agricultural practices using a qualitative approach with five purposively selected participants. Data collection included semi-structured interviews, field observations, and document reviews, analyzed through thematic analysis. Results reveal that farmers are adopting practices such as integrated pest management, organic fertilizers, efficient water use, and resilient seed varieties. However, barriers such as economic constraints, knowledge gaps, and inconsistent institutional support hinder broader adoption. The findings emphasize the need for targeted policy interventions, capacity-building programs, and leveraging community networks to enhance resilience. This study contributes to understanding how grassroots-level adaptations can mitigate climate impacts and promote agricultural sustainability in Indonesia.

Abstract

This study aims to describe the role of customary law and the concept of ethnoecology in supporting sustainable agricultural practices, while analyzing their integration as a model of agriculture based on local wisdom. The study used a qualitative approach with field study and literature study methods. Primary data were obtained through in-depth interviews, participatory observation, and focus group discussions with customary leaders and farmers, while secondary data were obtained from customary documents and related literature. Data analysis was conducted using the interactive model of Miles & Huberman through data reduction, data presentation, and drawing conclusions through source triangulation. The results show that customary law plays a role as a local regulation in agricultural management, while ethnoecology exists as a technical practice that maintains ecosystem balance. The integration of the two forms a sustainable agricultural system, not only increasing productivity but also maintaining environmental sustainability and strengthening social solidarity. This study confirms that customary law not only has social value but is also an ecological instrument relevant to modern sustainable agriculture.

Abstract

This study examines the role of community participation in mangrove forest conservation in Kaimana Regency, West Papua, using a qualitative approach with five key informants, including local residents, community leaders, and environmental activists. Data were collected through in-depth interviews and field observations, then analyzed thematically. The findings reveal that community participation is central to mangrove conservation, manifested in activities such as planting, monitoring, and protecting mangroves from exploitation. Local wisdom and traditional norms, rooted in indigenous culture, serve as guiding principles that reinforce compliance and foster a collective sense of ownership. Nevertheless, challenges such as limited financial resources, lack of technical expertise, and external pressures from aquaculture and coastal development threaten the sustainability of these initiatives. Collaboration with NGOs, universities, and government agencies has strengthened local capacity, yet policy support remains inconsistent. This study concludes that integrating local wisdom, empowering communities, and fostering multi-stakeholder collaboration are essential strategies for effective and sustainable mangrove management in West Papua.

Abstract

The research aims to understand how the local implementation of ethnoecological knowledge is integrated with adaptive farming practices to enhance agricultural resilience and environmental sustainability amidst climate change and identify factors influencing the successful adoption of these practices and their potential for broader adoption within the context of Indigenous community agriculture in similar regions. This study employs a qualitative research approach, specifically a single holistic case study. This approach allows for an in-depth exploration of knowledge-based approaches to adaptive agriculture among vegetable farmers in Dieng, Java. Data analysis technique will follow Miles and Huberman's interactive model, which involves a systematic process of data reduction, data display, and conclusion drawing. Based on the findings in the study, it was concluded that, several key factors greatly influence the successful adoption of indigenous agricultural practices. These include the active involvement of community leaders and elders who have in-depth knowledge of effective traditional practices and government support through subsidies, loans and policies that support customary land rights and sustainable agricultural practices.
