ANALISIS PENYEBAB BEBAN PENCEMARAN DAERAH ALIRAN SUNGAI (DAS) JANGKOK DARI ASPEK FISIKA DAN MIKROBIOLOGI

Abstract

Water is one of the essential resources which people need while the pollution in Jangkok river of West Nusa Tenggara has negatively affected its ecosystem. Building on this issue, it is considered that there is a need to analyse the culprits behind the issue especially in terms of the related trends of pollution loads. This research aims to  examine the development of pollution loads from its physical aspects namely water debit and temperature as well as through the microbiological aspects such as E coli and Total Coliform of Jangkuk Rivershed which then will be followed by figuring out the ways in which the rivershed’s sanitation is managed. The development of debit, temperature, E coli and Total Coliform factors could be projected through data analysis from BISDA DPUP NTB from 2009 to 2012. From the analyses, it is concluded that for physical aspects, which are debit and temperature, the pollution load trend is relatively constant as the analysed debit and temperature indicated that the two are constant with their natural states which are ± 3˚C. Meanwhile for microbiological factors which are E coli and Total Coliform, the trend is relatively decreasing so that it is concluded that the solution applied by the local authority, BISDA DPUP NTB, has been already successful in reducing the pollution loads related to microbiological factors. However, there is still a need to reduce the pollution loads of Jangkok Rivershed. The steps needed are: socialization towards people near the river on the importance of waste management, proper land use as well as the construction of community-based integrated domestic waste management.
