Introduction: The increase in medical waste in health service facilities in Indonesia is linearly consistent. The quantity of medical waste that causes a complex problem is a high cost of processing clinical waste. Legislation requires medical or clinical waste to be processed not to cause nosocomial and other environmental pollution. Medical or clinical waste treatment requires excessive technology and very high processing expenses. Processing medical waste requires innovation in processing medical waste to be applied easily in health care facilities (Public Health Center). Method: This research was conducted by simulating variations in the stages of processing medical waste used to be the Experiment Pre and Post Test only without Control Group design. Simulation variations used include contact time Chlorine (5 minutes, 10 minutes) and Chlorine Dose Variation (25 ppm, 50 ppm). This research was conducted in the Public Health Center of the City of Banjarbaru in 2018. Result and Discussion: The content of bacteriological numbers in medical waste before processing is, on average, 1,973 MPN / 100 ml; after being treated with MWT-P, the bacteria is reduced to 4 MPN/100 ml. The content of the liquid waste bacterial number of the final processing decreases to 0 MPN/100 ml. Conclusion: The study results concluded that the use of MWT-P decreases the quantity of medic or clinical waste microorganisms or bacteria. The final waste processing with MWT-P resulted in the number of medical waste bacteria in the treatment reaching zero. MWT-P is a low cost and easy to perform medical or clinical waste management tool. MWT-P is a stage of the B3 waste management framework, especially medical waste, in health care facilities.

Distance of Aerated Tray and Length of Deposition Time in Reducing Iron (Fe) Level in Drilled Well Water. Well bore wijaya street 7 Kelurahan Sungai Paring, Kecamatan Martapura, physically looks yellowish and slightly tasted. Based on the preliminary test of iron content of 3.50 mg / L and pH 4 compared to Republic of Indonesia Minister of Health Regulation No. 32 of 2017, has not met the requirements, namely iron 1.0 mg / L and pH 6.5-8.5. The purpose of this study is to find out the magnitude of the effect of the distance of aeration Tray on decreasing the iron content of borehole water and pH on borehole water. Type of experimental research with Pretest-Postest Without Control Group. The population in this study was all water in the wellbore. The sample of this research is borehole water. Analysis of the effect of variations in height and duration of settling using the Two Way Anova test shows sig. (0.000) <α (0.05). Based on the results of research with the method of aeration Tray can reduce iron content with a percentage of 1 meter 96.28-90.71%, 1.5 meters 81.57-73.57% and 2 meters 71.35-64.64%. This shows that the highest variation in altitude decreases iron content in bore well water, which is 2 meters and the duration of deposition time is 3 hours. It is recommended to treat the water with an aerated tray. You need to add coagulant and sand filters. Variations in height of 2 meters and the duration of deposition of 3 hours can be used as an alternative water treatment.

Brackish water caused of high chloride sodium content, giving to feel briny at water. The only chemical process can remove chloride is the ion exchange. The aim of this study was to determine the difference of percentage decreasing of chloride levels in variations of chloride level in brackish water (870 mg/l, 1712 mg/l, 2501 mg/l) and variation of sampling time (1,5 hours, 3 hours, 4,5 hours). Brackish water used the result of dilution of brines using freshwater. This process brackish water by passing into a resin media tube’s diameter 5cm and 40cm high with flow discharge 100ml/min. The results of chloride levels after the process still exceeded the quality standard Permenkes RI No.492/MENKES/PER/IV/2010. The avarage chloride levels after from the chloride 870 mg/l is 776,7 mg/l, the chloride 1712 mg/l is 1520 mg/l and the chloride 2501 mg/l is 2139 mg/l. From Two-Way-Anova test showed a significant difference between the percentage of decreasing chloride levels in various sampling time, the variation of initial chloride level, and interaction between variation in initial chloride content and sampling time.

Aedes aegypti mosquito is a type of mosquito that can carry dengue virus which causes dengue fever (DHF). Dengue transmission can be reduced by vector control to reduce the population of Aedes aegypti mosquitoes, namely by reducing larval growth. Eradication can be done by giving environmentally friendly plant larvaside. Plants that have the potential as vegetable larvasides are papaya leaves (Carica papaya).. The type of research used is true experiments. The study design uses an e-simple design (post-test only control group design). The population and sample were 3 Aedes aegypti instar larvae obtained in the Banjarbaru region. With a total of 600 tails. With variations in concentration of 0% (control), 6%, 8%, 10%, 12%, and 14% with 4 repetitions at each concentration. then observed the number of larvae that died for 24 hours.Based on the results of research conducted for 24 hours with papaya leaf larvasidehighest concentration14% / 100 ml of water can kill larvae as much as 96% with an average death of 24 animals. With statistical testsAnova Ona Way is p = 0,000

White Turmeric Larvicides (Curcuma zedoaria) Against Death of Aedes sp. Larvae. Dengue Hemorrhagic Fever is a disease transmitted through mosquito bites from the genus Aedes sp. Chemical control is carried out by killing larvae using abate but can cause resistance from the target organism, to solve this problem by using natural insecticides, namely white turmeric. This study aims to determine the effectiveness of white turmeric larvae (Curcuma zedoaria) on the death of Aedes sp. Larvae. The type of research used is pure experiment. In this study researchers can control the course of the experiment. The sample used was 25 larvae which were put into container boxes with various concentrations and length of contact time. The results of the analysis of concentration variations showed sig <α (0.247> 0.05). The duration of contact showed sig <α (0.004 <0.05). The concentration variation has no effect while the contact time has an influence on the mortality of Aedes sp. Larvae. The LC50 value at 72 hours contact time is 0.25% and TU 400 value. The effectiveness of white turmeric larvacide is at a concentration of 0.6% which can kill 88% of target insects / animals. Suggestion, to reduce the aroma of white turmeric as larvacide. Need to test other mosquito larvae. At the contact time of 48 hours with a concentration of 0.6% ± 1 teaspoon the juice of white turmeric rhizome in 1 liter of water was said to be effective.
