Abstract
Klampok River is a river located in Semarang Regency, Central Java, which is in the Klampok Sub-watershed part of the Jragung Watershed. This 16-km-long river crosses four sub-districts in Semarang Regency, namely Bandungan, Bawen, Bergas, and Pringapus. Most of the land use along the Klampok watershed is for agricultural, residential, plantation, and industrial activities. This study aims to find out the water quality in Klampok River using Water Quality Index National Sanitation Foundation method and analyze the influence of land use and land cover (LULC) towards water quality with descriptive analysis. Land use patterns were analyzed using ArcGIS 10.3.1 software. Overall, the index value shows that the Klampok River is in good status and based on Government Regulation no. 82 of 2001, only the Fecal coliform parameter exceeded the quality standard. The highest index value (77.41) is in segment 2 with dominant land use in the form of agriculture and settlements and the lowest (73.88) in segment 4 with land use in the form of plantations, residential, and industrial activities.
Highlights
Based on data from the Central Statistics Agency (BPS) of Semarang Regency, the population of Semarang Regency in 2018 is 1,040,629 people [1]
Changes in land cover are a form of environmental degradation which is interpreted as a form of human intervention on land to meet the life needs, both material and spiritual [2]
Based on the results of the research and considering discussion in the previous chapter, the following conclusions can be drawn: 1. The water quality level of the Klampok River based on the National Sanitation
Summary
Based on data from the Central Statistics Agency (BPS) of Semarang Regency, the population of Semarang Regency in 2018 is 1,040,629 people [1] This shows an increase of 13,140 people or 1.28% compared to 2017. The increase in population growth rate causes various environmental degradations, as an impact in the effort to meet life needs. Changes in land cover are a form of environmental degradation which is interpreted as a form of human intervention on land to meet the life needs, both material and spiritual [2]. This land cover change occurred in several areas, including in the watershed area.
