Aim: This study is to determine effect of contamination level of population settlement activity on water quality in the reservoir at west Sunter by measurements of reservoir water quality in the form of physical and chemical parameters including the identification of the kinetics of COD. Methodology and Result: This research was conducted in April to August 2016 with 11 sampling locations. Research indicated that the reservoir had experienced heavy pollution with DO value ranging between 1.05 mg/L-1.52 mg/L with a minimum quality standard of 3 mg/L, Ammonia 0.13 mg/L-0.38 mg/L with a quality standard of 0.02 mg/L, surfactant (1.74 mg/L-4.63 mg/L) quality standard of 0.2 mg/L and phosphate (0.8 mg/L-1:19 mg/L) to the quality standard of 1 mg/L. Reservoir also were polluted with heavy loads inclusion of organic content with COD values ranging between 112.58 mg/L - 196.39 mg/L. The source of pollution in the west Sunter reservoir was derived from domestic sewage. Based on the average constant value it takes 16.96 hours to reduce the COD from 120 mg/L to 40 mg/L. Natural Retention time at West Sunter Reservoir is 13.6 days. Conclusion, significance and impact study: Domestic waste has obviously contaminated West Sunter reservoir from its physically green color, high organic content with high COD values, low DO, high oil and fat content, and high phosphate levels. These polluted compounds must be removed before spreading to the next water body. If the reservoir is considered as a reactor site, then the reservoir must be able to remove the contaminants before disposal.

Radioactive liquid waste is a hazardous and toxic waste which comes from nuclear research laboratory. This waste may cause explosion when treated with evaporator. Aim: This research was intended to reduce and determine the best removal method of Cs-137 and Co-60 from radioactive liquid waste. Methodology and Result: Methods used in this research are ion exchange and coagulation-flocculation method. In ion exchange method used two types of reactor that is continuous reactor and batch reactor with variables of debit, material type, mesh size and mass of material, while in coagulation-flocculation method used jar test with ferro sulfate coagulant dose variables. Continuous reactor consisting of separating funnel and chromatography column with a diameter of 4 cm and height 60 cm, whereas in batch reactor used jar test stirrer. The application of radioactive liquid waste treatment is done using selected method, with the start condition for Cs-137 of 3 x 10-5 mCi/L and for Co-60 of 4.8 x 10-6 mCi/L. Application of Ion Exchanger with Continuous Reactor Speed 60 mL/10 sec and Coagulation-Flocculation with dose of 100 mmol/L in pH 8 effluent result the value for Cs-137 and Co-60 that undetected or very little, below 10-6 mCi/L. Conclusion, significance and impact study: The conclusion of this study is suitable with the Government Regulation Number 10 of 1997 about nuclear power, the limit of quality standard for Cs-137 and Co-60 is below 10-6 mCi/L. So the appropriate method to treat of Cs-137 and Co-60 are Ion Exchanger with Continuous Reactor Speed 60 mL/10 sec and Coagulation-Flocculation with dose of 100 mmol/L in pH 8.

Aims: This study was aimed to find out the relevance of social capital in kampung arrangement and also to understand the most influential element of the social capital and its role on the arrangement of kampung in Kampung Pisang. Methodology and results: The study investigated the elements of social capital that affect the activities in every phase in kampung arrangement process. This was done through the analysis of data resulted from the questionnaire and interview surveys on the residents of Kampung Pisang. The result showed the most influential element of social capital is the social network in participation variable. Conclusion, significance and impact study: Participation as an element of social capital plays a major role in kampung arrangement in Kampung Pisang, Makassar city in Indonesia. By participation, the relevance of social capital in kampung arrangement is developing people’s knowledge about the environmental quality and using it in the improvement of physical environmental condition. This paper showed that kampung arrangement could be done by using social capital to hinder evictions.

Publisher : Universitas Trisakti

Aims: This study is aimed to identify the hazards and occupational risk factors of Hydrogen sulfide as one of the most dangerous gas exposures for employees coming from coal, oil and gas companies. Hydrogen sulfide is a toxic colourless gas with a characteristic odor, soluble in various liquids including water. This gas is irritant and asphyrant that can be absorbed through lung into blood. Its inhalation exerts hard damage of respiratory tract. Methodology and Result: The method used is the analysis of questionnaires with logistic regression statistics. The numbers of respondents are 170 people from the employment population who work in coal mining and Pertamina production units. Results obtained from workers' observations and H2S sampling suggest that the most dominant source of H2S exposure hazard comes from the skim tank and DAF areas. The variables associated with shortness of breath was age (P = 0.006). As many as 17.3% of workers did not apply proper work procedures, and 30.58% of workers had experienced work accidents. Conclusion, significance and impact study: H2S are not related to complaints of dizziness or shortness of breath of workers. Specific factors related to occupational safety are long-term exposure of work factors related to complaints of shortness of breath (OR = 2,061), and factors not using PPE associated with dizziness (OR = 3,484)

Aim:This research is aimed to study of organic degradation in Pluit reservoir, that located in the Village Penjaringan, North Jakarta, between 6° 07' 28.6" S 106° 48' 07.6" E and 6° 06' 40.2" S 106° 47'51.1"E with a broad area of ± 80 Ha, depth 1-8 meter. Flow systems pluit reservoir is half continuous and water is disposed with 4 units pump with a capacity of 4.5 m3/s which operates 8 hours/day throughout 11 pumps available. From the results of research findings are then compared with quality standards inspection according to the Government Regulation No. 82/2001 Class II for a review of recreation, fisheries and agriculture. Methodology and Result:The 90% of the DO value is ≤ 2 mg/L. The phosphate value obtained overall is not complied to the standard quality (≤ 0.2 mg/L P). In Pluit reservoir is found organic compounds as raw CODwhich was not complied to the standard quality (≤25 mg/L COD) approximately 27.52 mg/L COD - 371.52 mg/L COD. A kinetics test was done in order to determine the decreasing rate of COD in two conditions, where the first aeration to initial DO reached 4.5 mg/L, and the second is without aeration. Conclusion, significance and impact study:The COD degradation towards time is then measured and shows that organic degradation rate towards time without aeration process shows no decreasing, while non-aerated condition shows that the reaction rate following first pseudo reaction is 0.096 hours-1 – 0.133 hours-1 with an average value of 0.1177 hours-1.

Air pollution problem is faced by many countries in the world. Ambient air quality studies and monitoring need a long time period of data to cover various atmospheric conditions, which create big data. A tool is needed to make easier and more effective to analyze big data. Aims: This study aims to analyze various application of openair model, which is available in open-source, for analyzing urban air quality data. Methodology and results: Each pollutant and meteorological data were collected through their sampling-analysis methods (active, passive or real-time) from a certain period of time. The data processed and imported in the openair model were presented in comma separated value (csv) format. The input data must consist of date-time, pollutant, and meteorological data. The analysis is done by selecting six functions: theilSen for trend analysis, timeVariation for temporal variations, scatterPlot for linear correlation analysis, timePlot for fluctuation analysis, windRose for wind rose creation, and polarPlot for creating pollution rose. Results from these functions are discussed. Conclusion, significance and impact study: Openair model is capable of analyzing a long time air quality data. Application of openair model is possible to cities in Indonesia that already monitor ambient air quality but have not analyzed the data yet
