Pendampingan Pembentukan PKBM (Pusat Kegiatan Belajar Masyarakat) di Desa Mandiangin Kecamatan Rawas Ilir Kabupaten Musi Rawas Utara

The aim of community service is to assist in the formation of the PKBM (Community Learning Center) in the Mandi Angin Village, Rawas Ilir, Musi Rawas Utara. The method used is the method of socialization, training and practice. This PKBM is a mentoring activity that drects to the formation of the PKBM structure (The center of community learning activities). This is the concern of the PKBM team because in the Mandi Angin village has not yet formed a learning center for the community. PKBM assistance activities (the center of community learning activities) will increase SDM leading to SDM productivity in Mandi Angin village. The results of the PKBM (community learning activity center) activities in the Mandi Angin village of Rawas Ilir sub-district, kabupaten Musi Rawas Utara, including: 1) The implementation of STKIP-PGRI Lubuklinggau team with the village government, so that the activities took place safely and smoothly, 2) The implementation of the socialization of the PKBM structure (community learning activity center) and responded wel by the community, 3) the device and the community who were enthusiastic in bathing to support the formation of PKBM in the village, 4) The constrains faced were related to the difficulty in getting high competent communities, as part of the PKBM structure, and 5) The village government and the community demanded that the PKBM activities be carried out well, not just in the form of structuring their activities. In general the results of this PKBM are the formation of the PKBM structure which will be continued at the level of PKBM implementation.

Structure Community of Phytoplankton in Floating Net Cages at Buyan Lake Sukasada District, Buleleng, Bali Province

Danau Buyan merupakan sumberdaya alam akuatik yang mempunyai nilai yang sangat penting. Pemanfaatan danau buyan diantaranya adalah kegiatan budidaya keramba jaring apung yang berpotensi memberikan masukan nutrien kondisi ini dapat mempengaruhi kualitas air yang kemudian akan berpengaruh pada fitoplankton. Tujuan penelitian ini adalah untuk mengetahui struktur komunitas fitoplankton dan kualitas perairan di area keramba jaring apung Danau Buyan, Kecamatan Sukasada, Propinsi Bali. Penelitian ini dilaksanakan pada bulan Januari-Maret 2016 di area keramba jaring apung Danau Buyan, Kecamatan Sukasada, Kabupaten Buleleng, Propinsi Bali. Penelitian ini menggunakan metode sistematic sampling. Lokasi stasiun pengamatan total berjumlah 8 stasiun, stasiun 1-7 terletak dekat dengan area budidaya keramba jaring apung sedangkan 1 stasiun kontrol berada jauh dari area keramba jaring apung. Kegiatan pengambilan sampel dilakukan 3 kali dengan selang waktu 3 minggu. Hasil penelitian menunjukkan terdapat 9 genus fitoplankton yang terdiri dari 24 spesies. Hasil kelimpahan fitoplankton rata-rata yaitu 1454 sel/l sehingga masuk dalam kategori perairan oligotropik, Indeks keanekaragaman 07647-1,8352, Indeks keseragaman rata-rata-rata 3937. Nilai indeks dominansi 0,4225. Nilai parameter kualitas air yang didapatkan antara lain yaitu nilai suhu sebesar 23,54-24,94oC, Nilai Kecerahan yaitu 66,41-251.06, Nilai kekeruhan yaitu sebesar 2,10-6,39 NTU, Nilai pH yaitu sebesar 7,56-8,93, Nilai oksigen terlarut (DO) yaitu sebesar 4,10-5,44 mg/l, Nilai nitrat yaitu sebesar 0,39-0,99 mg/l dan nilai fosfat yaitu sebesar 0,13-0,45 mg/l. Secara keseluruhan hanya parameter oksigen terlarut (DO) yang kurang mendukung kehidupan fitoplankton.
