Abstrak: Sungai Citarum memiliki tingkat pencemaran tinggi akibat banyaknya sampah, limbah domestik maupun limbah pabrik yang disalurkan ke badan air tersebut. Hal ini menyebabkan banjir di wilayah sepanjang Sungai Citarum salah satunya yaitu Kampung Daraulin di Desa Nanjung, Kecamatan Margaasih, Kabupaten Bandung. Untuk mencegah banjir pemerintah melakukan proyek normalisasi Sungai Citarum dengan mengeruk dan melebarkan sungai serta meluruskan bagian yang berkelok. Bagian tersebut ditutup. Masyarakat di sekitarnya khususnya penduduk di Kampung Daraulin memanfaatkan bagian tersebut sebagai tempat penampungan limbah domestik. Hal ini mengakibatkan turunnya kualitas air sungai tersebut yang dapat mempengaruhi kualitas air tanah di sekitarnya. Penduduk Kampung Daraulin memanfaatkan sumur gali sebagai sumber air untuk kegiatan sehari-hari. Padatnya penduduk di Kampung Daraulin menyebabkan lokasi sumur gali dengan tangki septik sangat dekat. Penelitian ini dilakukan untuk mengetahui apakah air tanah di Kampung Daraulin tercemar oleh limbah domestik. Penelitian ini diawali dengan inspeksi sanitasi melalui kuisioner dan dilanjutkan dengan pemeriksaan sampel air tanah di laboratorium. Pemeriksaan sampel air tanah ini dilakukan di beberapa titik sampling dengan menggunakan metode statistika Simple Random Sampling (SRS), meliputi analisa ammonium dengan metode nessler-spectrofotometri, nitrit dengan metode Reaksi Diazotasi-Spektrofotometri, nitrat dengan metode Brucin-Spectrofotometri, Fosfat dengan metode Stannous Chlorida-Spectrofotometri, dan analisa jumlah bakteri Escherichia Coli dilakukan dengan metode Jumlah Perkiraan Terdekat (JPT). Dari hasil pemeriksaan sampel air sumur gali di Kampung Daraulin diketahui bahwa beberapa sumur gali di Kampung Daraulin tercemar akibat limbah domestik.Kata kunci: Air Tanah, Limbah Domestik, Sumur Gali, Sungai dan Tangki Septik Abstract : Citarum River has a fairly high level of pollution because of domestic and industrial waste. The wastes are channeled to the river and that cause flooding in areas along the river. One of the areas frequently affected by floods is Daraulin Village in Nanjung, Kecamatan Margaasih, Kabupaten Bandung. To prevent flooding, the Government do a project for normalization of Citarum River. This project doing dredge, expand and extend the winding river. Part of the winding river is closed, but the surrounding community, especially the residents of Daraulin Village, make a river as reservoir for the domestic waste water. This cause reducting of the water river quality, which can also affect the quality of groundwater. The residents in Daraulin Village use dug wells as a source of water for their daily activities. The densely populated village cause location between dug wells and septic tank is very close. The study was conducted to determine the groundwater in Daraulin Village polluted by the domestic waste water. The study began with the sanitary inspection with questionnaire and continued with the analysis in the laboratory. The sampling points is using statistical methods Simple Random Sampling (SRS). The laboratory analysis includes the analysis of ammonium with Nessler-spectrophotometry method, analyses nitrit by Diazotasi reaction-spectrophotometry, analyses nitrate by Brucin-Spectrofotometri, phosphate by stannous chloride-Spectrofotometri, and analysis Escherichia Coli by Most Probable Number (MPN). The results of water samples from dug wells in Daraulin village show that some of the dug wells are polluted by domestic waste..

Transportation is one of the human needs in a big city like Jakarta. Currently, the implementation of public transportation is being scaled up to reduce vehicle emissions, especially those fueled by oil. One public transportation activity is electric trains that produce hazardous solid waste. This study aims to identify the generation and composition of hazardous waste from electric train transportation activities in Jakarta. This study uses quarterly secondary data from July 2019 to March 2020. The composition of hazardous waste is calculated based on the w/w weight ratio, then looks at the effect of time and phase of each time hazardous waste generation from electric train activities. The composition of the largest hazardous waste is contaminated packaging, scrap-contaminated, and contaminated waste is 28.14%; 23.34%; and 10.72%, respectively. The lowest hazardous waste generated is used lamps at 0.10%. Hazardous waste arises from activities that contaminate to produce hazardous or toxic properties. Based on the phase, solid hazardous waste is 96%, and liquid is 4%. The analysis of the variance test showed no significant difference in terms of time (sig. 0.679) and phase (sig. 0.534). Therefore, the data used show no difference in hazardous waste generated by time or phase.

The wastewater treatment plant (WWTP) at the Universitas Pertamina area is one of the campus's efforts to reduce the environmental impact of wastewater production. The processed WWTP can be processed into ready-to-drink water as an effort to reduce plastic waste. This plastic waste is usually produced by the consumption of mineral water products. The availability of ready-to-drink water in the campus complex is expected to increase the interest of campus residents to use tumblers and reduce the generation of plastic waste as well as university proactive efforts. The purpose of this study was to analyze the units needed to process WWTP effluent into ready-to-drink water by looking at various alternatives. This study uses the analytical hierarchy process (AHP) in determining the best alternative. The units required for each alternative are equalization tub, slow sand filter, and disinfection. Meanwhile, for processing, there are three alternatives, namely microfiltration (MF), ultrafiltration (UF), and combined microfiltration – ultra-filtration (MF-UF). The selection of these alternatives was adjusted to the criteria of cost, required membrane area, flux recovery after backwashing, and the effectiveness of total coliform removal. MF filtration technology is the largest weight, which is 0.381. Where the use of MF in the Universitas Pertamina area is cheaper and requires better area than UF and MF-UF technology.

Excessive water consumption to meet water needs has changed aquatic water quality and quantity. Focus on domestic wastewater treatment via built wetlands. Disinfection protects humans against disease-causing viruses, bacteria, and protozoan parasites in wastewater. This study planned the disinfection of artificial wetland wastewater to fulfill microbiological criteria. From the examined data, each unit's design criteria and disinfection effectiveness for the created wetland outlet in the WWTP unit will be discussed. The created wetland must process 8696 cfu/100mL of fecal coliform. Despite good processing efficiency, 94% of fecal coliforms do not fulfill quality criteria. WWTP's wetland emits 8.011 mg/L of Ammonia. 90% chlorine costs Rp. 35,000/kg on the market. Total disinfection costs are rough Rp. 1,018,210.73. Water quality, lamp output power, and exposure distance affect lamp intensity. The lamp's electric power controls the beam's intensity; the more power, the more emission. The emitted power isn't equal to the lamp's electric power. According to the state electricity provider, families with a 900VA power limit will pay Rp. 1,352/kWh in July-September 2021. Nine 30-W bulbs irradiate bacteria. The lights will run for 24 hours non-stop. Hence the monthly electricity usage is 194.4 kWh or Rp 262.829.00.

The Seroja Cyclone disaster that occurred from April to May 2021 in several areas in East Nusa Tenggara, Indonesia, caused casualties and damage to residents' houses. With so many residents affected, logistical assistance is urgently needed for victims who are still surviving. Community service team of Universitas Pertamina, namely “Universitas Pertamina Tanggap Bencana (UPTB)”, is one of the institutions that carries out the distribution of logistical assistance to victims of the Seroja Cyclone disaster. The suitability of the location and type of aid is an important thing to consider in planning the distribution of humanitarian logistical assistance. Therefore, the UPTB team used the Kepner-Tregoe Situation Appraisal method to determine priority locations for the distribution of aid by analyzing the level of urgency, the potential for problem growth, and the seriousness of the Impact experienced by residents in several candidate locations. Based on the results of the analysis, it was determined that two priority locations would receive assistance, namely sub-district of Namosain and Waipare, Watumilok Village. The suitable types of aids for the two locations are also identified, namely basic necessities (groceries), medicines and building materials. Through the evaluation of the questionnaire, the residents rated that they were very satisfied with the distribution of the logistical assistance they received.
