Methodology and Result: This research was conducted in the irrigation channel that crossed next to Cicabe former waste disposal site. Pollutant parameter studied was Chromium (Cr) in water and sediment. To determine the pollutant transport along flow was using the equation of 1-dimensional analytical model based on advection–dispersion phenomena. The sampling was done twice for model calibration and validation. The samples collected included sediment and water. Pollutant input generated from leachate, domestic waste, and the open channel. The Cr simulation for k = 3 x 10-4/sec resulted that the model concentration was quite valid to approach observed Cr in observation and calibration. Simulations also done each segment to approach Cr observation with k1 = 2.5x10-4/sec, k2 = 1.1 x 10-3/sec, and k3 = 0/sec. Conclusion, significance and impact study: Cr concentration in the water met the quality standard according to PP 82/2011, while the Cr concentrations in sediment were above the US-EPA standard (2004). The simulation result for calibration and validation with k=1.4x10-4 Cr/sec showed the model was sufficient approaching the observed Cr. The Cr simulation indicated that the Cr had decayed as evidenced by the quite high Cr concentration in sediment.","PeriodicalId":329428,"journal":{"name":"INDONESIAN JOURNAL OF URBAN AND ENVIRONMENTAL TECHNOLOGY","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114661430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Until now, the application of solid waste management system in Jayapura is still far from what people expected since it has been unable to serve the communities who live in rural areas on the islands around Sentani Lake. As a result, 12,554.38 liters/day of solid waste generated by the community in these regions is left untreated. Methodology and Results: The study is using the Analytic Hierarchy Process (AHP) method. The AHP calculations show that the idea of handling solid waste in an integrated treatment facility—following the initial sorting on the household scale—has the highest priority weight (2.05) compared to the other alternatives. Hence, it has been chosen as the best solid waste management concept that can be applied to the study sites. Based on the results as well, the main criteria to be considered include the environmental aspects, social aspects, and technical aspects with each weighing value of 0.534, 0.186, and 0.147, respectively. Conclution, significans and impact study: The sub-criteria with the highest priorities to be considered in making the decision are the soil pollution (due to produced leachate), air pollution (potentially in the form of stench and gas emissions), the transmission of disease vectors, public participation, and the operational convenience.","PeriodicalId":329428,"journal":{"name":"INDONESIAN JOURNAL OF URBAN AND ENVIRONMENTAL TECHNOLOGY","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128789665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim: The aim was conducted to investigate the potential presence of helminth eggs causing STH infections in two urban agricultural areas in northern and southern part of Bandung City. Methodology and results: Samples of water from the inlet and plantation area, as well as soil and water spinach produced by both regions, were collected and analyzed for the presence of helminth eggs using modified Bailinger methods. The number of helminth eggs of 1–119 eggs/L in water, soil, and vegetable samples. Conclusion, significance, and impact study: The results confirmed that the irrigation water used in both areas has been contaminated by feces. The average number of fecal coli exceeds the allowable value for the irrigation water source based on the Grade 4 of water quality criteria in Indonesia. Variations in the number of helminth eggs found in the samples can be caused by environmental conditions such as temperature, humidity, and soil types. The presence of helminth eggs in irrigation water and land samples exceeds the value recommended by WHO (2006) in the guidelines for the safe use of wastewater for agriculture. It can lead to an increased risk of helminth infection to consumers, agricultural workers, as well as residents around the farmland.","PeriodicalId":329428,"journal":{"name":"INDONESIAN JOURNAL OF URBAN AND ENVIRONMENTAL TECHNOLOGY","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124409548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
