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.

Mosquitoes are type of insect that acts as a disease vector. One of them is Culex sp mosquitos which their existence is many around us. In Indonesia there are still a lot of disease cases that caused by Culex sp mosquitos, one of them is filariasis disease. The efforts to control thecurrent population of Culex sp mosquitoes mostly use chemical insecticides. The control becomes difficult because of the resistance to chemical insecticides and adversely affects the environment. This study aims to determine the potential of jackfruit leaf extract as biolarvasida against Culex sp. The type of this study was post test onlycontrolled group design, using 625 larvae Culex sp instar III, divided into 5 groups (negative control group, 0.25% extract, 0.50% extract, 0.75% extract, extract and 1% extract). Observation was performed 24 hoursafter the treatment and counted the number of larvae death.The data were analyzed by Kruskal Wallis test followed by Post Hoc Mann-Whitney U test to determine the killing power of leafy leaf extractusing Probit analysis. The results of data analysis in this study were thedeath rate percentage of larvae after 24 hours treatment was 0% incontrol, 44% in 0.25%extract, 52% in0.50% extract, 60% in 0.75%extract,while in the extract group of 1%, the number of larval deaths was 72%. Itobtained results with significant differencein some treatment groups thatwere concentrations of 0.25% - 1%. Probit analysis showed that LC50 wasat 0.382% concentration.From results of the studyit can be concluded that jackfruit leaf extract(Artocarpus heterophyllus Lamk) was potential as Culex sp mosquitobiolarvacide. So it is necessary to conduct further research on the effectsof compounds that contained in other plant parts such as flowers, stemsand roots which will be expected to have a function asbiolarvasida.Keywords: Leaf Jackfruit, Biolarvasida, Mosquito Culex sp

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.

Semakin banyak macam jenis kegiatan yang berkembang di daerah perkotaan menyebabkan bertambahnya pula volume serta karakteristik air limbah, salah satunya adalah usaha jasa laundry. Penelitian ini bertujuan untuk mengetahui efektivitas tanaman mangrove jenis Rhizophora mucronata dalam menurunkan kadar detergen di dalam air limbah hingga sesuai dengan Peraturan Gubernur Jawa Timur Nomor 72 Tahun 2013. Penelitian ini merupakan penelitian Eksperimen Semu. Analisis data dilakukan secara analisis statistik ANOVA.Berdasarkan hasil penelitian dari beberapa reaktor dapat dinyatakan bahwa besaran tingkat penurunan kadar detergen bervariasi pada waktu 2 hari, 4 hari, dan 6 hari. Hal tersebut membuktikan bahwa akar tanaman mangrove jenis Rhizophora mucronata mampu menyerap kadar detergen yang terdapat pada media tanam dengan sangat efektif. Penurunan kadar detergen pada air limbah tidak hanya dipengaruhi oleh adanya tanaman mangrove, namun juga dipengaruhi oleh mikroorganisme yang terdapat pada susunan reaktor buatan yang berupa kerikil dan ijuk. Selain penyerapan oleh akar, bagian tanaman mangrove lain yang dapat menguraikan zat pencemar adalah bagian daun dan batang. Penurunan kadar detergen terbesar pada reaktor D dengan jumlah 4 tanaman dalam waktu tinggal selama 6 hari dengan penurunan hingga 6,4 mg/L. Sedangkan penurunan kadar detergen terkecil pada reaktor A dengan 0 tanaman dalam waktu tinggal selama 2 hari dengan penurunan hingga  Perlu dilakukan penelitian lebih lanjut dengan jenis tanaman mangrove yang berbeda spesiesnya, misalnya Bruguiera gymnorrizha, Avicinea marina, Soniratia casularis. Kata kunci : mangrove, detergen, waktu detensi

Aktivitas pelayanan medis rumah sakit menghasilkan limbah medis yang berbahaya jika tidak dikelola dengan baik, dapat berdampak buruk bagi kesehatan lingkungan sekitar. Penelitiam ini bertujuan untuk mengevaluasi pengelolaan limbah B3 medis di RSUD. dr. M. Soewandhie Surabaya. Penelitian ini bersitaf deskriptif dengan metode kualitatif.
