Abstract

Increasing the effectiveness and efficiency of rice harvesting (Oryza sativa. l) in west nabire district, nabire regency, aims to determine the effectiveness and efficiency of the use of Combine Harvester in rice harvesting in West Nabire District, Nabire Regency. This study used a survey method with a sample of 26 respondents by simple random sampling, with an interview method using a previously prepared questionnaire. The results of the study showed that the use of the Combine harvester harvesting machine was more effective than the manual rice harvesting process with an effective value of 1.073, with a cost reduction of Rp 747.385.4 and a reduction in grain loss during harvest of 586.44 kg. The use of Combine harvester has a beneficial impact because it can reduce production by Rp 747.385.4 and reduce crop loss by 586.44 kg of grain.

Abstract

This study investigates the traditional Dusung agroforestry system of the Airlouw Hamlet community in Nusaniwe District, Ambon City, focusing on its ecology and productivity as a sustainable source of food commodities. The research employs a review of the Dusung system's capacity to meet the daily subsistence needs of the local community through its regular and continuous management. Data were collected using a census of 30 Dusung managers, incorporating both primary data (direct observation and interviews) and secondary sources (literature and existing reports). Analysis was conducted descriptively using both quantitative (productivity metrics) and qualitative (management practices) methods. The findings indicate that the high productivity and yield potential of the Dusung system are critically dependent on the optimal ecological management practices implemented by the farmers. The traditional system, characterized by a mix of agricultural commodities and livestock integration, functions as a primary source of food for the Airlouw community. However, the study reveals that the size of the Dusung plot does not linearly correlate with the actual commodity yield. Therefore, optimizing the system hinges on enhancing management strategies rather than merely expanding land area.
