Indonesia is one of the gifted countries with abundant natural resources in many sectors such as plantation, fishery, agriculture, and mining. To support the rapid population development, the natural resources exploited massively to fulfill the needs of humans. As a result of this massive exploitation, environmental degradation could not avoid such as air, soil and water pollution. Virtue Dragon Nickel Industry, located in Konaweha watershed, indicates polluted the water in the Konaweha river. Therefore, this study aims to identify the pollution index water of Konaweha River through physical and chemical parameters as well as to recommend river management system. Sampling has taken in two places in river, which were first around the settlement and second around mining industry. Sampling analysis underwent in laboratory and Index of Pollution (IP) used to identify the level of pollution. The result shows that the highest pollution index is in location 1 located near the mining industry which is 7.20 IP and has moderate pollution level. This happens because in first location, the industrial disposal going to the river and the human activities such as agriculture, plantation and illegal sand mining. Meanwhile, in second location has lower index pollution at 5.40 IP. This is because, in second location, the primary source of pollution comes from human activities such as agriculture, plantation and illegal sand mining. © IJSTR 2019.
