    Abstract
    Have been done research about The Study of Diversity Plankton in Danau Toba District of Pangururan Regency of Samosir. This research is done with Purposive Random Sampling that is determining 4 research station of pursuant to difference of society activity in area. Samples were taken by 3 restating and 4 deepness at each station (0 metre, 4 metre, 8 metre and 11 metre). The result of research show that there were 7 class of plankton which included 2 class fitoplankton which devided into 18 family and 30 genus and 5 class 0f zooplankton which devided into 7 family and 15 genus. Total highest abundance pursuant to station obtained at station I that is 14945,22 ind/l while the lowest there is at station IV that is 3836,55 ind/l. At 8 metre deepness highest abundance at station I that is 16452,78 ind/l and the 4 metre lowest at station IV that is 3101,90 ind/l. The highest value of diversity index at station I that is 3,11 and the lowest at station IV that is 2,63. The highest value of equitability index at station II that is 0,89 and the lowest a station IV that is 0,83. According to statistical test that abundance of plankton at station was significance diffrence while the abundance of plankton at deepness not significance diffrence. From result of correlation analisys known that the relation between variety index and chemical physical factor value range from middle relation and strong
     
    Telah dilakukan penelitian dengan judul Studi Keanekaragaman Plankton di Perairan Danau Toba Kecamatan Pangururan Kabupaten Samosir. Penelitian ini dilakukan dengan metoda Purposive Random Sampling yaitu menentukan 4 stasiun penelitian yang berbeda berdasarkan aktivitas masyarakat. Pengambilan sampel dilakukan dengan 3 ulangan dan 4 kedalaman yang berbeda pada masing-masing stasiun penelitian (0 meter, 4 meter, 8 meter dan 11 meter). Hasil penelitian menunjukkan terdapat 7 kelas plankton yang terdiri dari kelas fitoplankton yang tergolong dalam 18 famili dan 30 genus serta 5 kelas zooplankton yang tergolong dalam 7 famili dan 15 genus. Total kelimpahan plankton tertinggi berdasarkan stasiun terdapat pada stasiun I sebesar 14945,22 ind/l dan total nilai kelimpahan plankton terendah terdapat pada stasiun IV sebesar 3836,55 ind/l. Total kelimpahan plankton berdasarkan kedalaman terdapat pada kedalaman 8 meter stasiun I sebesar 16452,78 ind/l dan kelimpahan terendah terdapat pada kedalaman 4 meter stasiun IV sebesar 3101,90 ind/l. Indeks keanekaragaman tertinggi terdapat pada stasiun I sebesar 3,11 dn terendah terdapat pada stasiun IV sebesar 2,63. Indeks keseragaman tertinggi terdapat pada stasiun II sebesar 0,89 dan terendah terdapat pada stasiun IV sebesar 0,83. Uji statistik menunjukkan kelimpahan plankton berdasarkan stasiun berbeda signifikan sedangkan berdasarkan kedalaman tidak berbeda signifikan. Dari hasil analisis korelasi hubungan antara faktor fisik kimia dengan indeks keanekaragaman berkisar antara berhubungan sedang dan kuat
