Karateristik ini memberikan pengaruh terhadap kualitas air. Salah satu yang mendapatkan pengaruh adalah keberadaan bakteri di perairan. Bakteri adalah mikroorganisme air yang berperan dalam proses dekomposisi di perairan. Tujuan penelitian ini adalah untuk mengetahui total dan profil bakteri di Waduk Jatibarang berdasarkan kedalaman. Penelitian dilakukan pada 27 Maret 2019. Metode penelitian yang digunakan adalah metode deskriptif dengan pendekatan studi kasus. Teknik pengambilan sampel menggunakan metode purposive sampling , yang dilakukan di tujuh stasiun dengan tiga titik kedalaman (permukaan, tengah dan dasar). Perhitungan bakteri total dilakukan berdasarkan SNI Nomor 2332.3.2015 tentang Uji Mikrobiologi-bagian 3: Penentuan Angka Lempeng Total (ALT). Pengelolaan data menggunakan aplikasi SPSS 20 dan analisis sebaran menggunakan Ocean Data View 4. Berdasarkan perhitungan bakteri total di Waduk Jatibarang, total bakteri di permukaan waduk berkisar antara 1,9 × 10 3 – 1,5 × 10 5 CFU/ml, pada tengah yaitu 1,3 × 10 2 – 1,5 × 10 4 CFU/ml dan pada dasar 1,5 × 10 3 – 2,7 × 10 4 CFU/ml. Analisa sebaran bakteri total di Waduk Jatibarang menunjukkan bahwa terdapat kecondongan perbedaan stratifikasi secara vertikal. Reservoir have vertical characteristic be affected by entering sunlight in to waters. This characteristic effected to water quality, such as total bacteria. Bacteria is water microorganism that being a decomposer in the decomposition process. The purpose of this research is to know the consentration and profile of total bacteria base on depth in the Jatibarang Reservoir . The research was conducted on March 27th 2019. The research methods use descriptive methods with case study , and technical sampling methods using purposive sampling in seven stations with three point s of depth water ( surface, middle, and bottom ). Accounting of total bacteria is base on the Standard National of Indonesia Number 2332.3.2015 about Microbiology Analisis-Chapter 3: Plate Number Determintion. Data processing use software SPSS 20 and distribution analysis with Ocean Data View 4. Base on the results, total bacteria in the surface level is 1,9 × 10 3 – 1,5 × 10 5 CFU/ml, in the middle is 1,3 × 10 2 – 1,5 × 10 4 CFU/ml. Total bcteria in the bottom level is 1,5 × 10 3 – 2,7 × 10 4 CFU/ml. Distribution analisis total bacteria in the Jatibarang reservoir show that there is different stratification of total bacteria in tendency vertically. }, issn = {2721-6233}, pages = {321--326} doi = {10.14710/marj.v8i4.26551}, url = {https://ejournal3.undip.ac.id/index.php/maquares/article/view/26551} }
