Abstract

Air sumur di Kelurahan Tarus diduga telah terkontaminasi nitrit dan kadmium yang berasal dari pemakaian secara berlebihan pupuk SP-36 dan Urea. Oleh karena itu, penelitian ini telah dilaksanakan untuk membandingkan konsentrasi kontaminan nitrit dan kadmium dalam air sumur di daerah persawahan dan pemukiman dengan ambang baku mutu air baku air minum dan memprediksi besarnya risiko dari kontaminan terhadap kesehatan manusia. Penelitian deskriptif eksperimental ini menggunakan maing-masing 10 sampel air sumur dari daerah persawahan dan pemukiman. Kadar nitrit dan kadmium dianalisis dengan metode spektrofotometri dan spektrofotometri serapan atom. Baku mutu air minum dan air baku air minum berdasarkan PP 82 tahun 2001 dan PerMenKes 492 tahun 2010. Prediksi risiko terhadap kesehatan manusia dilakukan berdasarkan metode analisis risiko Public Health Assessment. Hasil penelitian menunjukkan bahwa di daerah persawahan dan permukiman berturut-turut terdapat tiga dan lima sumur yang mengandung nitrit namun kandungan tersebut masih berada di bawah nilai baku mutu air baku air minum. Sedangkan untuk kadmium, terdapat berturut-turut delapan dan tujuh sumur di daerah persawahan dan permukiman kandungannya berada di atas nilai baku mutu air baku air minum. Analisis risiko menunjukkan bahwa nitrit di persawahan dan pemukiman tidak berisiko terhadap kesehatan, sedangkan kadmium persawahan dan pemukiman yang berisiko sebanyak 14 sampel untuk durasi waktu 30 tahun, 12 sampel untuk 20 tahun, 10 sampel untuk 10 tahun dan tiga sampel untuk lima tahun. Karena itu diharapkan adanya pengurangan volume konsumsi air sumur yang berisiko, dan penanganan air tanah yang tercemar serta pengurangan pemakaian pupuk anorganik.

Abstract

Hospital liquid waste has the potential to pollute the environment and harm health if not processed properly because it contains high enough organic and inorganic compounds, pathogenic microorganisms, toxic chemicals and radioactive substances. Rumah Sakit Umum Daerah (RSUD) Kefamenanu is the only hospital owned by the Government of Kabupaten Timor Tengah Utara and located in the middle of community settlements and uses wastewater treatment plants (IPAL) in the treatment of hospital liquid waste since 2016. The results of liquid waste quality examination showed that there are several parameters that have increased after processing through IPAL so that researchers use filtration method in processing liquid waste of RSUD Kefamenanu. This study aims to find out the effectiveness of liquid waste treatment of RSUD Kefamenanu through filtration process using filter media in the form of coconut coir, sand, palm oil, activated charcoal and zeolite. This research is a pseudo experiment, namely to find out the percentage of decreased levels of liquid waste parameters through the filtration process. The results showed that the levels after processing had an average value of BOD 3.86 mg/L, TSS 14 mg/L and ammonia of 0.10 mg/L. The filtration process was able to lower BOD levels by 63.62%, TSS by 93.24% and ammonia by 86.57%. Based on these results, it can be concluded that the filtration process is able to lower levels of BOD, TSS and ammonia in liquid waste of RSUD Kefamenanu.

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.
