Abstract

Along the coast Keluruhan Pelintung has been an abrasion of 1.33-16.84 metres/year. This activity aims to increase the capacity of community awareness of coastal damage mitigation through counseling on abrasion prevention and green belt implementation techniques. The methods used were lectures, discussions, and classroom and field practice, followed by 28 community representatives. The results of the activity showed a significant increase in community's understanding of simple methods to prevent coastal damage which had a positive impact on ecology (coastal resilience) and the economy (alternative income). The method of planting mangroves on abrasive beaches is due to the influence of currents and waves and processing of mangrove fruit to produce syrup, diamonds and mangrove dodol (mangrove). The results of the economic analysis show that the pedada syrup (1 bottle @ Rp. 25,000) generates a profit of Rp. 3,192,000/month, wajik pedada (1 pack Rp. 10,000) Rp. 1,476,000/month, and dodol pedada (1 pack of Rp. 15,000) Rp. 2,760,000/month. The majority of the community stated that they supported and enthusiastically held this activity, namely 49.7% (Strongly Agree), 37.8% (Agree), 11.80% (Neutral) could accept and practice increasing community awareness of mitigating coastal damage by making mangrove planting efforts and diversification of processed mangrove products.

Abstract

The role of housewives (Mitra Pengcinta Alam Bahari/PAB) contributes to the production of organic waste from cooking activities in the kitchen. For example, organic waste from vegetable residues, fruit (such as fruit peels, hard vegetable stems and leaves) and food waste. The problems faced are: the unknown technique of making eco-enzyme products to reduce pollution of environmentally friendly organic waste. One of the organic waste management techniques is the use of eco-enzyme products. The purpose of the activity is to increase the production capacity of eco-enzyme to be able to reduce organic waste pollution and to increase the entrepreneurial spirit of PAB partners to produce eco-enzyme products. The methods used are lectures, discussions and the practice of making eco-enzymes involving 20 PAB members. The results of the activity showed that PAB members were very supportive and motivated, as many as 53.0% (Strongly Agree), 42.4.0% (Agree) and 4.50% (Neutral) were willing to practice environmentally friendly eco-enzyme product utilization techniques. The results of the economic analysis of the production of 5 bottles/day of eco-enzyme products (@ Rp. 30.000,-) will generate a profit of Rp. 2,958,720/month. This provides added value for people's income and efforts to manage organic waste.
