Abstract

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)

Abstract

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.

Abstract

Aim: This study of plumbing system plan is  aimed at planning a plumbing system that is compatible with clean water, waste water and rain water management at Tunjungan Plaza apartment, Surabaya City, Indonesia according to SNI 8153-2015, and meet 5 aspects of safety, security, simplicity, beauty, and economy.  It applies water supply system which commonly used for tall buildings, namely Roof Tank system. Methodology and Result: Plumbing system planning methods are collecting and analyzing fluctuation in water use, planning clean water and recycled water systems by endorsing alternative piping for clean water and recycled water. In addition to water supply, recycled water system that utilizes waste water to be recycled for flushing closets and watering plants also required to be implemented. Average daily water consumption is 268 m3/day for clean water and 44 m3/day for recycled water with the capacity of ground water tank for clean water is 564.54 m3 and recycled water is 62 m3. Conclusion, significance and impact study: Clean water supply system will implement roof tank system and recycled water will reutilize wastewater for flushing on toilet tank and watering the plants. Waste water use separated system between grey water and black water and then distributed to STP to be treated and reused for flushing water closet and watering plants. Rain water goes to infiltration well by gravity through designed 1 well. Total amount of investment of plumbing equipment is Rp 2,157,697,501,- with cost of water supply per unit Rp 4,445,643,- meanwhile waste water piping cost per units is Rp 1,070,711,-.

Abstract

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
