| dc.description.abstract | Waduk Jatigede dibangun di atas wilayah seluas lima kecamatan. Aktivitas masyarakat di sekitar waduk dapat memberikan masukan bahan organik dan organik yang menyebabkan perubahan tingkat kesuburan perairan. Kesuburan perairan merupakan kemampuan tingkat produksi suatu perairan. Status kesuburan perairan umumnya dibagi menjadi tiga tingkatan, yaitu oligotrofik, mesotrofik, dan eutrofik. Penelitian ini bertujuan untuk menentukan tingkat kesuburan perairan Waduk Jatigede, Sumedang, Jawa Barat dengan beberapa pendekatan. Penelitian dilakukan pada bulan Februari sampai April 2021 yang diambil pada tujuh titik pengamatan. Status kesuburan perairan dianalisis menggunakan indeks Nygaard, indeks Thunmark, dan TSI. Hasil penelitian menunjukkan bahwa komposisi kelimpahan fitoplankton di perairan Waduk Jatigede didominasi oleh Cyanophyceae yang mengindikasikan perairan eutrofik. Status kesuburan perairan Waduk Jatigede berdasarkan indeks Nygaard, indeks Thunmark, dan TSI tergolong ke dalam perairan eutrofik. | id |
| dc.description.abstract | Jatigede Reservoir was built on an area of five sub-districts. Community activities around the reservoir can provide input organic and inorganik materials that causes changes in the level of trophic states. Trophic state is the ability of the production level of a waters. Trophic state is generally divided into three levels, namely oligotrophic, mesotrophic, and eutrophic. This study aims to determine the level of trophic state of Jatigede Reservoir, Sumedang, West Java with several approach. The study was conducted in February to April 2021 which was taken at seven observation points. Trophic state was analyzed using Nygaard index, Thunmark index, and TSI. The results showed that the composition of the abundance of phytoplankton in the waters of Jatigede Reservoir was dominated by the Cyanophyceae which indicated eutrophic waters. The trophic state of Jatigede Reservoir based on Nygaard index, Thunmark index, and TSI is classified as eutrophic waters. | id |
