PENGOLAHAN KRIPIK PISANG

Merauke Regency has very abundant banana production, which in 2012 reached a production of 11,970 tons, equivalent to about 1,197,000 banana bunches per year (assuming a weight of 1 bunch = 10 kg). The types of bananas produced are more than 90% of kepok banana types, but unfortunately this huge potential has not been widely used to support local food self-sufficiency. The potential of bananas can be processed into banana chips and able to absorb and open new jobs. In the processing of banana chips, the problems encountered are the mechanical difficulties in the manual slicing process and the conventional frying process. This causes the production of banana chips not uniform, ineffective, fast rancid chips, short shelf life, decreased taste and appearance of chips. Through the application of slicing and spinner machine technology, counseling and assistance in SMEs by the Implementation Team. The IbM results obtained were uniform thickness and non-oily banana chips production, increased effectiveness of production time, supply of quality and continuous kepok bananas, orderly and good financial bookkeeping.   Keyword: slicing, spiner, banana chips, not oil

Changing Livelihood Strategies in a Conservation Area: Fishers, Farmers, and Sand Mining in Merauke, Indonesia

The Wasur National Park (WNP) includes the Ramsar Site, an important area for global conservation efforts in wetlands. This coastal area also supports the socio-economic activities of local and non-local communities who are highly dependent on natural resources. Conservation efforts in the area are sometimes at odds with the sustainability of local livelihoods and poverty alleviation initiatives for the community. The aim of this study is to describe the sources of community livelihoods in the Wasur Naukenjerai National Park area, specifically around agricultural, fisheries, and sand mining dynamics. Using a qualitative research design, this study uses a field survey to collect primary data sourced from key informants with in-depth interviews from 15 community respondents in three sample villages on the coast, and seven key informants from relevant government agencies. The results show that the main livelihood source for people in the protected area are as fishermen and farmers. Sand mining has emerged as an alternative source of livelihood but has caused degradation of beaches and land in the Wasur National Park area. In addition, there are activities of buying and selling agricultural land in protected areas. The protection of the rights of the community in the area and government support programs have been unable to guarantee the welfare of the community. For this reason, it is necessary to strengthen and further support local institutions livelihoods to ensure the sustainability of Wasur National Park area management
