The city of Kupang is one of the developing cities and this has an effect on people's lifestyles and consumption patterns. The increasing purchasing power and competitiveness of the community towards various types of basic materials and technological products make a major contribution so that it indirectly contributes to the quality and quantity of waste. The final waste processing site (TPA) in Kupang City is located in Alak District with an area of 9.14 Ha and has been operating since 1998. Based on DLHK calculation data, the amount of waste generated every day is 86 tons of waste. The operation of the Alak TPA uses the controlled landfill method, but in practice the waste that enters the TPA does not go through a sorting and recycling process, but is directly disposed of in a landfill which is then covered with white soil and pressed with heavy equipment. The generation of waste in Kupang City has increased every year because not all waste can be managed properly. The problem of waste management in Kupang City is the limited capacity at the TPA, the slow processing of waste, and the increasing volume of waste, so that it is necessary to carry out a systematic, comprehensive and sustainable waste management including limiting waste generation, recycling waste, and/or reuse. rubbish. Determination of the location of the urban waste landfill must pay attention to the city development plan, the economic capacity of the local government as well as the physical and geological conditions of the planned area and must be in accordance with the planned period so that there is no accumulation of waste that can have an impact on health, environment and social and economics due to lack of land availability for waste disposal. Therefore, it is necessary to estimate the amount of waste generated in the City of Kupang and determine the need for land area to accommodate waste in landfills according to the plan period. Based on the results of the study, the total amount of waste generated in the planning year period was 8,336,498.4 m3 with a landfill area of 63.92 Ha, and a buffer area of 15.98 Ha. The soil covering the waste layer to be compacted in the TPA on the surface of the waste is about 15 m from the thickness of the pile.

Population growth can cause a decrease in water quality in raw water sources due to human activities and land use around the source. Water that can be consumed must meet the Regulation of the Minister of Health of the Republic of Indonesia No.492/MENKES/PER/IV/2010, which includes physical, chemical and biological requirements. One of the chemical parameters in water quality requirements is the amount of calcium (ca) and magnesium (mg) in the water, the presence of which is known as water hardness. The maximum level of hardness that is allowed in drinking water according to the Minister of Health of the Republic of Indonesia Number 492/MENKES/PER/IV/2010 is 500 mg/liter. The source of raw water used by PDAM Kupang City comes from ground water and surface water. Based on chemical examination of water samples, Namosain spring has a high level of hardness, namely 606 mg/L CaCO3 compared to other springs. Lamella Separator is a sedimentation technology for purifying and recycling water and separating particles and turbidity from dirty water. Based on the author's previous research, the lamella separator was able to reduce the hardness up to 89.287%. So that the lamella separator can be used as an alternative treatment to reduce hardness on a household scale in Kupang City. The lamella separator application is planned to serve residents in Kupang City with a population of Kupang City in 2021 as many as 455.847 people with the assumption of kk 5 people so that the time required to treat 1497.64 L of water per day is 1.1 hours and the volume of the reservoir designed must be able to accommodate the volume of water of 15,000 m3.

Kelurahan Oesapa merupakan kelurahan yang masuk dalam kawasan kumuh dengan jumlah penduduk tinggi yang dapat meningkatkan jumlah timbulan sampah organik. Berdasarkan hasil observasi di lapangan, Kelurahan Oesapa tidak memiliki Tempat Pengolahan Sampah (TPS) organik. Oleh sebab itu perlu ada pengolahan sampah organik secara berkelanjutan. Tujuan dari penelitian ini adalah untuk mengetahui timbulan sampah organik dan mengidentifikasi skema pengolahan sampah organik. Skema pengolahan sampah organik dapat ditentukan dengan menggunakan beberapa skenario pengolahan sampah organik dengan menggunakan metode dinamis. Dalam metodde ini terdapat sub sistem jumlah penduduk dan sub sistem volume sampah organik. Hasil penelitian menunjukan bahwa pada tahun 2033, jumlah penduduk di Kelurahan Oesapa diprediksi sebanyak 34.979 orang dengan jumlah timbulan sampah organik sebesar 16,1953 m3/hari. Pengolahan sampah organik saat ini masih menimbulkan masalah sampah karena terdapat 9,4386m3/hari sampah organik yang belum dikelola dan 6,0672 m3/hari sampah organik yang terangkut ke TPA. Simulasi sistem dinamis menunjukan skenario pengolahan sampah yang pertama merupakan skenario terbaik untuk mengatasi masalah timbulan sampah organik di Kelurahan Oesapa dengan jumlah sampah organik yang terolah dengan sistem komposting sebesar 2,3599 m3/hari dan terdapat 12,5860 m3/hari sampah organik yang dapat diolah pada TPS-3R dengan metode BSF sehingga jumlah sampah yang terangkut ke TPA hanya sebesar 0,7866 m3/hari.

Well water is one of the water sources that is still used by the community for consumption and to fulfill other household needs. Community well water near the Carolus Borromeus Hospital has the potential to become contaminated. This research was conducted to analyze the spatial distribution of well water quality around St. Carolus Borromeus Kupang. This study aims to determine the quality standards of well water around the St. Carolus Borromeus Kupang and determine the spatial distribution pattern of groundwater around St. Carolus Boromeus. The method used in this research is taking samples then analyzing them in the laboratory and then comparing the results of physical, chemical and biological analysis with the applicable water quality standards according to their intended use. The spatial distribution pattern uses the parameter distribution pattern analysis method. The research results show that based on physical, chemical and biological analysis, in hospital outlet liquid waste there are several parameters that meet quality standards, but there are parameters such as Total coliform that do not meet quality standards. The results of parameter analysis in SG1 well water which is close to the hospital, several parameters meet quality standards, but the Fecal Coliform parameter does not meet quality standards for hygienic and sanitation purposes. The level of spread of contamination from organic matter and bacteria in groundwater is influenced by the type of soil, slope and direction of groundwater flow. The lower an area, the higher it is

Liquid waste generated from hospital activities since the Covid-19 pandemic has increased in quantity and contains microorganisms, especially the Corona virus, toxic substances, blood, body fluids sourced from Covid-19 isolation patient activities, treatment rooms, laboratory rooms, equipment and linen washing rooms. Hospital X is one of the Type C Hospitals in Kupang City that handles Covid-19 patients with liquid waste sources originating from the Emergency Room, Hospitalization, Operating Room, ICU Room, Laboratory, Radiology Room, Pharmacy Room, Kitchen, Office, and Laundry. To treat liquid waste generated from each unit, Hospital X uses a Wastewater Treatment Plant (WWTP) with a physical and biological treatment process and uses a closed piping system with gravity flow and pumping. Based on the results of the examination of physical parameters (temperature and pH), chemical parameters (BOD5, COD, TSS, NH3 Total, Oil and Fat, and MBAS), and microbiological parameters (Total coliform) have met the environmental quality standards in accordance with Permen LHK 68/2016 and Permen LHK 05/2014. The liquid waste treatment process at Hospital X is in accordance with the Decree of the Minister of Health of the Republic of Indonesia Number: 1204 / MENKES / SK / X / 2004, namely the hospital has carried out its own liquid waste treatment using a Waste Water Treatment Plant (WWTP).
