Abstract

The Surabaya River plays an important role as water supply of the Surabaya PDAM, irrigation, industry, transportation, and means of recreation. However, domestic, industrial, and agricultural waste that were discharged into the river stream polluted the Surabaya River and decreased the carrying capacity and assimilative capacity. Therefore, effort to monitor and control the Surabaya River water pollution need to be well organized and implemented. The aim of the research is to develop a model of water pollution control on Surabaya River region. The research was carried out based on field survey, in situ and laboratory sample examination, questionnaire, and expert judgment. Pollution control model developed in this study was built into three sub-models, namely: (1) ecology sub-model, (2) social sub-model, and (3) economy sub-model using powersim constructor 2.5 version. Pollution control scenarios were developed using prospective analysis. The results of water pollution parameters such as TSS, DO, BOD, COD, N-NO2, and the level of mercury (Hg) were higher than the allowable class 1 standard. The sources of Surabaya River pollution mainly are domestic and industrial waste with total load of BOD, COD, and TSS are 55.49, 132.58, and 210.13 ton/day, respectively. According to water quality status, the Surabaya River is categorized as heavy polluted and the loading pollution need to be decreased. By using prospective analysis, there were five important factors that affect the future of the Surabaya River water pollution control, i.e.: (1) population growth and community awareness, (2) community perception, (3) implementation of regulations, (4) commitment/local government support, and (5) system and institutional capacity. There are three development scenarios, that are pessimistic, moderate and optimistic. The moderate and optimistic scenario are the realistic scenarios that occur in the future for Surabaya River water pollution control in considering of ecology, social and economy aspects.

Abstract

Biknoi River is potential to be polluted by domestic cesspool because it crosses settlement area. It is important to be paid more attention because the water from Biknoi River is used as the basic source of Municipal Waterworks (PDAM) of Kupang town. The aims of the research are identifying the society along the riversides’ habitual in throwing out the domestic cesspool which potential to reduce the quality of the water in that river, evaluating the waters’ quality, knowing the contribution of the society’s domestic cesspool towards the water’s quality in Biknoi dam, knowing the level of water pollution by using Pollution Index method and knowing the effort for solving this problem.This research combined physical research and social research. Physical research was done by chemistry analysis for the sample of water, while the social research was done by having an interview which used questionnaire. The result of this research showed that there was a strong relationship between the society’s habitual with the reduce of the water’s quality of Biknoi River. The reduce of the water’s quality showed by the result of pollution enumeration index i.e. medium pollution category. The biggest pollution is COD i.e. 28.996 ton / month. The effort to solve this problem is by making the society to be aware, cesspool management, aware of rules, critical area rehabilitation, real action, controlling and layout.
