Community health centers are releasing infectious wastewater that must be treated using a Wastewater Treatment Plant (WWTP). The performance of WWTP will affect the quality of effluent wastewater, while the quality has been determined by the Governor of East Java Regulation No. 72 of 2013, so as not to pollute the environment. This research purposed to evaluate the management of WWTP incommunity health center in Surabaya, which covers the north, south, east and west. This research analyzed the installation of 5 wastewater treatment plants, consisting of 2 WWTP Non-Inpatient Health Centers with the highest population category, and 3 Inpatient Health Centers with the highest number of beds. Data collection was obtained from observations, interviews and laboratory tests. Wastewater samplings were carried out at the inlet, after filtration and outlet. Data were analyzed descriptively and compared with East Java Governor Regulation No. 72 of 2013 and WWTP Technical Guidelines. The results of the research showed that the effluent quality of the Surabaya City Health Center wastewater treatment plant has met the quality standards. The discharge of wastewater community health centersnot exceed the maximum discharge of wastewater, but the Tanah Kalikedinding and the Jagir Health Center produced wastewater exceeding the discharge capacity of WWTP, so that the performances becomes less efficient. In terms of management, only Dr. Soetomo health center had sufficient grades, while others got excellent grades.

Clean water is a basic need for living things, one source of clean water is groundwater. The problem that is often encountered in groundwater from dug wells is the content of heavy metal Fe. The purpose of this study was to determine the effectiveness of the absorption of heavy metal iron (Fe) in well water with Pistia stratiotes L. and Echinodorus palaefolius for 14 days using a phytoremediation process. This type of research is an experimental design using a pretest-posttest model with a control group that compares the occurrence of differences in the decrease in iron (Fe) levels of 9.86 mg/l in well water by collecting data by examining the results of iron (Fe) levels in well water. before and after treatment. Analysis of the data using the Independent T-test. The results of the study showed a decrease in iron (Fe) levels in well water after the phytoremediation process for 14 days. In Pistia stratiotes L. the level of iron (Fe) in well water was 0.67 mg/l and Echinodorus palaefolius was 0.58 mg/l. The effectiveness of Pistia stratiotes L. was 92.85% and Echinodorus palaefolius was 93.81% in reducing iron (Fe) levels in well water. Phytoremediation using Pistia stratiotes L. and Echinodorus palaefolius is effective in reducing iron (Fe) levels according to Permenkes No. 32 of 2017. The phytoremediation process using Pistia stratiotes L. and Echinodorus palaefolius can be recommended to reduce iron (Fe) levels in well water so that it meets quality standards.

Restaurant  liquid waste is waste originating from the operational activities of a restaurant which is largely unprocessed, but disposed of directly to the receiving water body. This study aims to reduce Biogeochemical Oxygen, COD (Chemical Oxygen Demand), TSS (Total Suspended Solid) in restaurant wastewater by processing aerobic biofilter using caldness media.            This type of research is an experiment with pretest-posttest research design. In this design, it is done to find out the initial condition of the subject before being treated so that it can determine the condition of the subject under study before the treatment can be compared or seen changes in the analysis of data used using the Pretest-Posttest test in order to determine the differences in 2 treatment groups.            The results of examination of the levels of BOD, COD and TSS before treatment with the BOD Caldness medium were 333,822,00 mg/ liter, COD was 575,535,00 mg/ liter and TSS was 580,136,00 mg/ liter. After treatment with a medium of Caldness of BOD of 580 mg / liter, COD of 1019 gr / liter, and TSS of 430 gr / liter.            The conclusion of this study is that the results obtained after processing used Kaldnes media were very  in reducing BOD by 99.98%, COD by 99.82% and TSS by 99, 92% in restaurant wastewater treatment.Keywords: Restaurant Wastewater, BOD, COD and TSS
