Anopheles Sp mosquitoes around the world contain about 2000 species, while those that can transmit malaria are about 60 species. According to observations in Indonesia found 80 species Anopheles Sp, while the vector malaria is 22 species with different breeding places. This study aims to determine the effectiveness of leaf, skin, and lemon juice on the death of Anopheles Sp larvae. This study is an experimental study to determine the effectiveness of lime in deadly mosquito larvae Anopheles Sp. The samples used in this research are Anopheles Sp instar III and IV mosquito larvae. This test is done every 3 times for 6 hours and observed every 1 hour. The results of this study showed that lime by comparing leaf, skin, and lime juice for 6 hours with 20 Anopheles Sp mosquito larvae in each experiment showed that using lemon leaf solution the highest number of deaths on 6 hours observation 16,7 tail (83,5%), lemon peel solution highest average death rate at 6 hours observation as much as 19,3 tails (96,5%), and lime juice the average number of death highest at 6 hours of observation of 19 tails (95%). Based on the research results, it can be concluded that lime is able to kill Anopheles Sp mosquito larvae with effective comparison is lime skin with percentage of death of 96%. Should approach the community and socialize the potential of natural resources, in this case the use of lime as a natural larvacide to reduce the number of larval populations and can be applied as a method of overcoming malaria and can develop penilitian utilization of lime.

Background: Waste is one of the most serious environmental problems being faced by people in Indonesia. The waste generated every day mostly comes from household activities as much as 37.3%, both organic and non-organic waste. Waste problems are influenced by many factors, one of which is community behavior, including the resulting waste is even disposed of in various places or burned around the residents' residences, the effect of which will damage the surrounding environment. Purpose of this study was to determine and analyze the effect of the emo demo method on the knowledge, attitudes, and actions of waste sorting in the district. Mamuju. Method: This study uses a non-equivalent pre-post test control group design. The sample in this study is housewife in Ex. Binanga as the control group as many as 25 people and Batu Pannu Village as the intervention group as many as 40 people Results of this study indicate that there are differences in knowledge, attitudes, and actions regarding waste sorting before and after counseling with the emo demo method, there are no differences in knowledge, attitudes, and actions regarding waste sorting before and after counseling with the triggering method. Conclusions and suggestions in this study are counseling with the emo demo method can increase knowledge, attitudes, and actions in sorting waste, it is suggested to policymakers to be able to use the emo demo method for sanitation programs. Key words: emo demo, waste sorting, triggering.

The population number of Aedes aegypti larvae is closely related to the increasing number of Dengue Haemorrhagic Fever (DHF) cases. This research was based on a problem occurred in 2014 in which 17 sufferers of dengue fever cases in Mamunyu village, Mamuju Regency, West Sulawesi Province. This research aims to know the population density of Aedes aegypti larvae by calculating the value of House Index (HI), Bretau Index (BI), and Density Figure (DI). The applied method was descriptive design with random sampling system. The data collection was done by conducting a direct survey through observation to each house. The results showed that the larval population in Mamunyu Village, Mamuju sub-district, was at moderate risk with density figure of 2-4 based on the results of the examination of HI (16%), CI (2.4%) and BI (20%). These results were close to the predetermined threshold, that it has the potential to cause transmission of DHF. In conclusion, the population of Aedes aegypti larvae by looking at the examination results of HI, CI, and BI is close to the predetermined threshold. It suggests that the community, health workers, and related institutions paying attention in the availability of the larvae and doing early prevention.

The entry of domestic wastewater into the aquatic environment will result in major changes in the physical, chemical and biological properties of the waters such as temperature, turbidity, recruited oxygen concentration, nutrients, and production of toxic materials.The level and extent of the effect that is generated on these aquatic organisms is highly dependent on the type and amount of pollutants entering the waters. Changes in the balance between physical-chemical and biological factors in an environment due to the presence of polluting compounds that can affect organisms in that environment. One way to find out how far the pollution load on wastewater is by measuring BOD and COD. Efforts to process domestic waste (greywater) in a simple way, namely by processing aerobic and anaerobic biofilter. The purpose of this study is to develop a household wastewater treatment system with an infiltration well model. This type of research is experimental research with the method of one group post test. Analysis of laboratory tests conducted at the Mamuju Ministry of Health's Integrated Polytechnic Laboratory to determine the effectiveness of household wastewater treatment using the infiltration well construction model, in reducing BOD and COD levels. The wastewater treatment system with the approach of infiltration well construction model effectively decreases BOD by an average of 92.69% from the initial level of 287 mg/L to 20.97 mg/L and COD an average of 85.72% from the initial level of 562 mg/L to 80.25 mg/L. The results of the study were declared effective and fulfilled the quality standard requirements of PermenLHK No.P68 of 2008 concerning domestic waste quality standardsIt is recommended to do media types, and use variations in residence time.
