This research aims to determine the value of primary productivity by using light-dark bottles at different depths in Jatigede Reservoir, Sumedang, West Java. This research was conducted from October 2020 until March 2021 using survey method research. Determination of the research location was done by using the purposive sampling method. Sampling was carried out at five stations and three depths: surface, 0.5 compensation depth, and compensation depth. The results showed that the primary productivity in Jatigede Reservoir ranged from 300.29-1013.47 mgC/m3/day. The results of supporting water quality parameters are light transparency ranging from 38-150 cm, temperature ranging from 26.6-29.7 oC, pH ranging from 6.69-8.7, carbon dioxide (CO2) ranging from 4.4-22.0 mg/ l, dissolved oxygen (DO) ranged from 3.00–6.6 mg/l, Biochemical Oxygen Demand (BOD) ranged from 1.62-16.22 mg/l, ammonia ranged from 0.0004-0.0055 mg/l, nitrate ranged from 0.017-0.044 mg/l and phosphate ranged from 0.06-0.14 mg/l. Based on the value of primary productivity, the waters of the Jatigede Reservoir are categorized as mesotrophic waters.
