Abstract

About 80% of the water used by humans for their activities will be thrown back in the form of wastewater from industrial and domestic. The source of waste in the lake at Residential X in Cibitung is residential activities. This study aimed to determine the ability of Betel Ivory (Epipremnum aureum) to reduce pH, turbidity, and ammonia in lake water that was contaminated by domestic wastewater and to determine whether the phytoremediation carried out using Betel Ivory (Epipremnum aureum) can be applied in Residential X Cibitung. The experiment was carried out using a batch system for phytoremediation, with a volume of Betel Ivory (Epipremnum aureum) of 13% w/w and a waste retention time of 7 days. Parameter reduction results were obtained using Betel Ivory (Epipremnum aureum), where the sample experienced a higher reduction rate in decreasing the concentration of pH, turbidity, and ammonia parameters when compared to the control. The phytoremediation using Betel Ivory (Epipremnum aureum) significantly impacted the pH, turbidity, and ammonia parameters according to analysis using one-way Anova Single Factor, and the findings of the study using the T-test of equal variance met the quality standard but did not comply. The potential for phytoremediation by using Betel Ivory cannot be realized because the depth of the lake reaches 7 meters and has a large number of plants.

Abstract

The solid management system in Taman Sari district, West Jakarta still uses collect-transport-dispose system. The population of Taman Sari District is 130,110 people with a total waste generation of 399,96 m3/day. This study aims to evaluate the operational technical aspects of the waste management system in Taman Sari district, which includes solid containerization, collection, and transportation of waste to final disposal at TPST Bantargebang. This research was conducted using primary data collection methods and secondary data obtained by conducting interviews, questionnaires, and field observations. The sampling method used is the Stratified Random Sample technique using the variable income level of the community at the sampling location, low income, middle income, and high income. The Taman Sari district sampling location selected 3 (three) locations namely Pinangsia Village, Krukut Village, and Keagungan Village which resulted in 45 samples for domestic waste and 26 samples for non-domestic waste. The observation results show that the aspect of waste disposal in low-income settlements is inadequate, while the aspect of disposal in middle-income and high-income settlements and commercial areas already has adequate disposal. The solid collection aspect of Taman Sari district consists of direct individual, indirect individual, and direct communal patterns. However, the solid transportation pattern in low – high income settlements only has 1-2 rounds which results in TPS overload. Therefore, the solid management system implemented in Taman Sari district needs to be evaluated to determine suitable alternatives for improving the existing conditions of the operational technical aspects of waste management in Taman Sari district.

Abstract

Abstract: Fabrication activities in the factory area have the potential to cause noise. Noise can cause feelings of discomfort, which can lead to difficulties in direct communication, cause cognitive decline, and contribute to job burnout. This study focuses on assessing the noise level caused by activities at the Engineering Workshop PT X, workers' perceptions of work fatigue, and the effect of noise levels on worker fatigue. Objective: This study aims to analyze the noise level, to analyze work fatigue, and to determine the relation of noise level on work fatigue. Method and results: The method used is the measurement of daytime noise levels at the specified point and time and questionnaire data collection. The results of measuring the noise level at the Engineering Workshop PT X, it is known that the lathe area shows a value of 74.1-77.0 dB, the refurbish area shows a value of 84.2-86.9 dB, and the grinding machine area shows a value of 71.5-79.7 dB. Questionnaire data on the level of work fatigue, showed that 25 respondents or 80.6% experienced mild fatigue and 6 respondents or 19.4% experienced moderate fatigue. Chi-Square statistical test showed the value of p = 0.37 (α < 0.05). Conclusion: Only refurbish area that produce noise level above standard. From questionnaire, most of respondents experienced mild fatigue. By using Chi-square analysis, it can be stated that there is no relationship between noise level and work fatigue on workers at Engineering Workshop PT X.

Abstract

Abstract. Emissions are the result of human activities that increase the concentration of greenhouse gas gases such as CCl2F2, CO2, N2O, and  CH₄, Increasing the attention of the gases above will increase the greenhouse effect which ultimately increases the earth's temperature. The existence of a waste management site can produce greenhouse gas emissions from vehicle transportation, composting processes, TPA to recycling. One of the roles of Flamboyan's TPS3R is to reduce the amount of plastic waste by recycling and composting and the residue will go to Cipeucang TPA for landfilling. This is an effort to reduce the amount of organic and non-organic waste, but the recycling, and composting. Landfilling processes can produce CO2 in the waste processing and distribution process, so it is necessary to calculate the amount of CO2 from the baseline management of municipal solid waste that will be compared with alternative municipal solid waste scenarios to see the conclusion of the analysis using the Waste Reduction Model (WARM) application. Objectives: The objective of this journal is to calculate the greenhouse gas emission and energy use of TPS3R Flamboyan. Method: The secondary data was obtained from TPS3R Flamboyan’s management. The writer use description analysis. Result: 1.     the inventory calculation result of GHG emission current condition and alternative condition are -5,24 and -6,5. 2.   Total energy use in the current condition is -58,79 and the alternative condition with HDPE recycling is -92,68 Conclusion: 1. the inventory calculation result of GHG emission current condition and alternative condition are -5,24 and -6,5. 2. Total energy Use in the current condition is -58,79 and the alternative condition with HDPE recycling is -92,68.
