Abstract

Community service activities titled Transforming Organic Waste into Organic Fertilizer in Namo Bintang Village in May - November 2019. This activity aims to convert organic waste into organic fertilizer that has economic value, and does not endanger the environment. The method used is counseling, lectures and training as well as monitoring and evaluation with the community directly to the field. Organic waste processing is carried out in several places in the village of Namo Bintang with the approval of the village head and the community. The activities are carried out by means of counseling and lectures, explanations of theories and integrated waste management techniques that are followed by the farmers and scavenger groups of Namo Bintang Village. The community listens to the material delivered by the community service team. The training was conducted by community groups of farmers and scavengers in Namo Bintang Village. Peasant and scavenger community groups are trained by the community service team. All carried out this activity by proactively conducting training to get results in the form of fertilizer from organic waste. The results were reviewed by community groups after 10 days of training to see organic fertilizer. The equipment for utilizing organic waste is also very simple so that community groups can make it themselves. And finally the monitoring and evaluation of the success of monitoring the work in the field will be carried out by going directly to the field together, monitoring by visiting to find out whether the community can do it themselves, besides that the relationship will be carried out by telephone to overcome the problems that arise. In general, community service activities have been successfully carried out and seen a good cooperative relationship between the Higher Education, especially the Implementation Team, government officials and the community in Namo Bintang Village. The village community realizes the importance of saving the environment from increasing their life expectancy because they can make their own fertilizer / compost.

Abstract

Plankton is aquatic organism that flying and its moves within the water current. Plankton is classified into phytoplankton (classified as plant) and zooplankton (classified as animal). The present of plankton in the water is determined by the physic and chemical condition of the water. Plankton has a limitation to tolerate the environment parameter so, its diversity is different depend on physical and chemical conditions. This research was conducted during April to May of 2013. The sample was taken from four observation stations 4 repetitions. Using Purposive Random Sampling with method. The result of research indicates thast there are 7 class of phytoplankton,they are : Bacillariophyceae, Chlorophyceae, Conjugatophyceae, Coscinodiscophyceae, Cyanophyceae, Eulenophyceae, Ulvophyceae and 12 class of zooplankton, they are : Branchiopoda, Cladocera, Clitellata, Copepoda Crustaceae, Filosia, Gastropoda, Lobosea, Monogonta, Oligotricheae Tubulinea, and Turbellaria The highest total number of plankton is found in station 4 (2043,707 ind/l) and the lowest total number of plankton isfound on station 3 (1519,707 ind/l). The highest diversity index value (H'-) for each station is found onstation 3 (1,206) and the lowest on station 4 (0,929).
