Abstract

Greenhouse Gases (GHG) consists of various types of gases that are produced either naturally from the environment or from the activities of living things, some examples of the dominant GHGs are water vapor, carbon dioxide (CO2), methane (CH4), nitrogen oxides ( NOx) and Sulfur Oxide (SOx), the largest contributors to GHG emissions are in the Energy sector, amounting to 175.62 million tons of CO2. Microalgae are the most primitive plants, can grow in low water quality with the availability of adequate nutrients and sunlight. The amount of CO2 that can be absorbed by 1 kg of dry spirulina is 1.83 kg of CO2. In addition, Spirulina Platensis can tolerate gas content of SOx, NOx and CO2 whose concentrations are <12%. This study aims to determine the process of utilizing CO2 gas emissions from PLTGU for the cultivation of Spirulina Platensis microalgae at PT. Indonesia Power UPJP Perak Grati. Based on the research results, the average emission load value generated from PLTGU, especially HRSG 1.1, is 10,403.31 tons CO2 / month on average. The temperature factor has a significant correlation with the growth of microalgae cells with an inverse correlation. Based on the tests carried out to determine the relationship between changes in the flow rate of CO2 in microalgae cultivation ponds to the growth of microalgae cells, it was found that the addition of CO2 in the cultivation pond with a flow rate of 1 L / minute had a greater effect than other treatments. The amount of CO2 absorption by microalgae installations with a flow rate variation of 1 liter CO2 / minute is able to absorb 0.2766 tons of CO2 / month, or is only capable of <1% of the average emission load of HRSG 1.1 per month.

Abstract

The communal domestic wastewater treatment plant functions to collect and treat domestic wastewater at the source location according to the communal scale treatment capacity. The communal Wastewater Treatment Plant (WWTP) in RT (neighborhood association) 01 / RW (citizen association) 09 Sindangrasa was built in 2016 using the Anaerobic Baffled Reactor (ABR) system. This study aims to evaluate the Communal WWTP by analyzing the quality of wastewater compared to PerMenLH No. 68 of 2016, calculates the processing efficiency and analyzes the water quality of the community wells around the Communal WWTP compared to regulation of PerMenKes No.416/MENKES/PER/IX/1990. Data collection techniques using the Slovin technique in the pre-research stage, direct sampling on location and testing in an accredited laboratory. The results showed the quality of wastewater exceeds the quality standard for BOD, TSS and Total Coliform parameters, the quality of residents' well water exceeds the quality standard for parameters pH, Cr VI and Total Coliform. Communal WWTPs in RT 01/ RW 09 Sindangrasa have not been efficient in treating residents' domestic wastewater. The management of Communal WWTPs needs to be improved so that the effluent quality and processing efficiency values ​​meet the specified regulatory standards.

Abstract

This study aims to determine the sanitation conditions of buildings and cleaning facilities at an Environmental Services Company. In this research, the Importance Performance Analysis (IPA) mapping of each attribute of the assessment of the sanitation condition was evaluated so that it can be seen which assessment attributes have low values and need to be assessed to get corrective action as a top priority. This research is descriptive quantitative research by collecting data through direct observation and distributing questionnaires to all employees of the Environmental Services Company. The results of 20 respondents were processed using the SPSS 16 application. The results showed that the sanitation conditions of the buildings and cleaning facilities at the Environmental Service Company did not meet the requirements. Priority mapping of the sanitation attributes of buildings and cleaning facilities using the Importance Performance Analysis (IPA) method can be seen in the Cartesian diagram. The result shows that from all 17 building sanitation attributes, there are 3 attributes in quadrant A. While 7 attributes are in quadrant B, 3 attributes are in quadrant C, and 3 attributes are in quadrant D. Of the 46 sanitation attributes for sanitation facilities, there are 8 attributes in quadrant A, 24 attributes in quadrant B, 13 attributes in quadrant C, and 1 attribute in quadrant D. Attributes that have low scores on building sanitation, namely the yard and roof of the building, while in sanitation of cleaning facilities, namely lockers in the changing room, trash cans, and sanitary napkins.

Abstract

Waduk Jatiluhur adalah bendungan multiguna pertama di Indonesia yang disediakan 12,9 miliar m3 / tahun potensi air. Dalam operasi sekitar 15 tahun terakhir dengan aktivitas industri, meningkatkan populasi, mengurangi kondisi DAS dan lebih meningkatkan keramba jaring apung di area reservoir Jatiluhur yang ditunjukkan dengan adanya penurunan kualitas bendungan air. Tujuan penelitian ini supaya dapat mengetahui kualitas air dan tingkat pencemaran air di waduk Jatiluhur yang disebabkan keramba jaring apung. Penelitian ini dilakukan dalam lima titik pengambilan sampel: Poin 1: Kerenceng; Butir 2: Jamaras; Butir 3: Bojong; Butir 4: Sodong; Butir 5: Parung Kalong. Parameter kualitas air yang dulunya adalah indikator adalah Oksigen Terlarut atau Oksigen Terlarut. Hasil dari penelitian menunjukkan bahwa keramba jaring apung berpengaruh terhadap penurunan pencemaran air di waduk Jatiluhur, terdapat peningkatan pencemaran air di waduk Jatiluhur yaitu 512, 89 mg / detik.
