<p>The increase of population in an area will have an impact on the level of density of the area, so that the emergence of a wild settlement that utilizes the river area as a place of residence. This condition will be a potential waste problem in the Riverbank area. One of them is the potential for garbage dumped into rivers, especially Cikapundung River. Tamansari Village is one of the areas that are traversed Cikapundung river, so it takes the planning of the system of inheritance and garbage collection to reduce the potential of waste dumped into the river. waste generation measurement based on SNI 19-3964-1994 method. The concept of waste management system planning is the reduction of waste in the source by 30% with the planning of the timing system through sorting based on three categories of garbage types. Planning of collecting system is by giving the gathering to the collecting device compartment. A community-based waste processing approach that starts from sourcing through composter processing and garbage bank.</p>

The hospital is a health service building, a place of transmission of disease and allows environmental pollution and health problems. One of the prevention of disease transmission and environmental pollution, it is necessary to do repairs and improvements by using a plumbing system to have good sanitation and environmental friendly. In this case, needed to know how much water can save by method comparing between plumbing tools conventional and non-conventional standar. UNSRAT's hospital has a population of 2,962 people who needed clean water distribution of 372,48 m 3 / day. Compared by using conventional plumbing tools is 66,72 m 3 /hari, meanwhile non-conventional plumbing tools is 39,60 m 3 /hari, it shown that using non-conventional plumbing tools standard is more saving than conventional standard, where percentage non-conventional water saving is 40,64%. Also expected that the resulting domestic wastewater will be reduced by 31,68 m 3 / day. This is more important than water savings in the amount of Rp. 3.564.000 and domestic wastewater treatment costs Rp. 9.500.000. AbstrakRumah sakit merupakan sarana pelayanan kesehatan, dimana memungkinkan terjadinya pencemaran lingkungan dan gangguan kesehatan, salah satu upaya untuk mencegah hal tersebut perlu adanya sanitasi pada rumah sakit. Maka dari itu, perencanaan sistem plambing hemat air ang bertujuan agar terwujudnya sanitasi yang baik dan ramah lingkungan. Penelitian ini bertujuan untuk mengetahui seberapa hemat penggunaan alat plambing tersebut dengan metode yang dilakukan yaitu membandingkan standar pemakaian air alat plambing konvensional dan non-konvensional. Rumah Sakit UNSRAT memiliki jumlah populasi sebanyak 2.962 orang sehingga diperlukan penyaluran air bersih sebesar 372,48 m 3 /hari. Perbandingannya pemakaian air pada alat plambing konvensional yaitu 66,72 m 3 /hari sedangkan pemakaian air alat plambing non-konvensional yaitu 39,60 m 3 /hari, dari perbandingan tersebut menunjukkan bahwa pemakaian air menggunakan alat plambing non-konvensional lebih kecil dibandingkan standar alat plambing konvensional dimana persentase penghematan mencapai 40,64%. Sehingga penggunaan alat plambing non-konvensional pula berpengaruh pada debit air limbah yang dihasilkan berkurang sebanyak 31,68 m 3 /hari. Hal tersebut pun berpengaruh terhadap biaya penghematan air yaitu berkurang sebesar Rp. 3.564.000 dan biaya pengolahan air limbah domestik berkurang Rp. 9.504.000.

Out of four waste banks in the Tanimulya Village, Sahdu Waste Bank is the only proper waste bank in operation. Based on the 2019 West Bandung District’s Environmental Agency (Dinas Lingkungan Hidup Kebersihan) Strategic Plan, which stated the target in 2022, that it needs to reduce 10%, from the current 8% reduction of the waste generation through the solid waste management and waste bank facilites, prior to the landfill. One of the efforts that can be done is through the development of the Sahdu Waste Bank from the hamlet scale to the urban village scale by using the Waste Bank Indexing Method. Assessing the existing condition with the waste bank index, identification and compiling the recommendation towards parameters that need improvement. Based on the results of the assessment, a score of 53.2 (out of 100, and is considered as fairly good category), reveals 14 sub indicator that can be improved, which consist of 6 Sub Indicator of Management System, 6 Sub Indicator of Operational System, and 2 Sub Indicator of Waste Bank Facility. The value of the Sahdu Waste Bank can be increased to 88.3 (out of 100, and is considered as very good), which generates the reduction of 266.67% of waste, equal to 4 ton/month from 150 kg/month. That would make Sahdu Waste Bank contributes 1.6% from the reduction target of 10% for the West Bandung District waste.

Food sanitation is one of the methods used to protect food from contamination, maintain quality, and prevent potential bacterial transmission. This research was conducted to observe potential diseases caused by the microbiological quality of clean water for household use. MPN method was used to compare the quality of clean water based on the Peraturan Menteri Kesehatan Nomor 416 Tahun 1990. Swab method was implemented to observe the hygiene level of the cutlery to compare with the Peraturan Menteri Kesehatan Nomor 1098 Tahun 2003. 79/100 ml of total coliform found in tenant 1 and tenant 2 which means it did not meet the standards. Escherichia coli were found absent in both clean water sources. The same result comes from 2 samples of plates and spoons before and after the first usage and second usage. In tenant 2, Escherichia coli were found in plate sample no.1 before usage and the clerk’s hands before serving the food. Hence, it did not meet the standards. Based on the interviews and observations, the sanitation hygiene of the clerks and the physical hygiene of tenant 1 and tenant 2 had only fulfilled 61.9% and 57.1% of proper hygiene, so it needed to be improved.
