The use of detergent in households is practiced by almost all people. These conditions make the quality of the environment, especially water bodies, more disturbed when the detergent waste disposal without prior processing. Hazard by detergent can interfere with human health such as digestive system disorders, skin irritation, and even one of the causes of cancer. The aimed of this research was to design a modified biofilter reactor to reduce levels of detergent and other organic substances in domestic wastewater. This research was a pre-experimental design research with designs used is pre-test, treatment, and post-test. The research media used were bioball because bioball has more space on its surface for bacterial growth that will form bacterial phylum, while activated carbon serves to increase efficiency in reducing levels of organic matter and to reduce the concentration of surfactants dissolved. The process is more effective if given a treatment with a process of coagulation, flocculation, and sedimentation. The results showed a decrease in detergent content from 14.56 mg/L to 0.86 mg/L (94.1%). These results indicate that the Bio Filter reactor was effective in reducing detergent levels to meet the detergent waste standard requirements based on East Java Governor Regulation No. 72/2013.

Continuous direct discharge of untreated laundry effluent into the streams may cause problems of water pollution and harm to human health. Treatment with biofilter is one chosen among the treatments for the effluent. It had the purpose of comparing the effectiveness of broken roof tiles and bioball as biofilter media in reducing the detergent levels of laundry effluent after aerobic treatment. The study was an analytic experiment using the one-group pretest-posttest design. Methods of analysis to test the differences in the effeciency of reducing detergent levels between broken roof tiles and bioball as biofilter  media combined with activated carbon using statistical test Independent Sample T Test. The parameter to be measured was detergent level by the use of Metylena Blue Active Subtances (MBAs) method.Results showed that the bioball biofilter reactor modified with activated carbon had the largest decrease in the level of detergent in the laundry effluent with efficiency of 1.61% after 160 minutes of flowing. Statistical tests showed that, p = 0,063 so p (sig) > 0,05 there was no significant difference in the efficiency of reducing detergent levels for both biofilter media.  Both biofilter media were not effective in reducing the levels of detergent since the effluent remained above the standard value. Utilization of biofilter technology requires a pre-treatment stage, such as coagulation-flocculation due to high levels of pollutants, in order to prevent effluent from polluting surfaces water. In addition, further studies are required which use the acclimatization process and different contact time and biofilter media as well as examining other parameters.   Keywords : Biofilter, Bioball, Broken Roof Tiles, Detergent Levels, Effluent of Laundry

One strategy to overcome the case of filariasis is by turning off the vector, namely Culex sp. Mosquitoes, and usually using chemicals as larvicides, in the long run, can cause resistance to larvae and environmental pollution. Bitter melon (Momordica charantia Linnaeus) and cucumber tree fruit (Averrhoa bilimbi Linnaeus) can cause death in larvae because they contain chemical compounds alkaloids, flavonoids, saponins, tannins, and are safe for animals and the environment. This study aims to determine the differences in the toxicity of Bitter melon fruit (Momordica charantia Linnaeus) and cucumber tree fruti (Averrhoa bilimbi Linnaeus) as Culex sp bio-larvacides. The research method was experimental, with the research design used is the post-test only control group design. Samples were Culex sp. third instar mosquito larvae. The study used 4 replications and 7 treatments with 25 larvae of each treatment. The concentration of bitter melon fruit (Momordica charantia Linnaeus) and cucumber tree fruit (Averrhoa bilimbi Linnaeus) were 0% (control); 11%; 22%; 44%. Data analysis was performed analytically using a probit test and a different test (Two Way Anova). The results showed a solution of bitter melon fruit (Momordica charantia Linnaeus) and cucumber tree fruit (Averrhoa bilimbi Linnaeus) had the potential as a bio-larvacide and had a mortality rate at 0% concentration (control), in bitter melon fruit concentrations of 11%; 22%; 44% of 73%, 89%, 100%. Whereas in cucumber tree fruit concentration 11%; 22%; 44; by 95%, 99%, 100%. The different test showed that there was a significant difference between control, bitter melon (Momordica charantia Linnaeus) and cucumber tree fruit (Averrhoa bilimbi Linnaeus) solution to Culex sp larvae mortality (α <0.05). Suggestions that can be given is that bitter melon fruit (Momordica charantia Linnaeus) and cucumber tree fruit (Averrhoa bilimbi Linnaeus) can be used as bio-larvacides and used as alternative larvacides as substitutes for chemical larvacides, and further research using different larvae is needed.

Hospital activities could be potentially reduces the quality of the environment and publichealth, especially from the medical home activities. One of this activity produces liquid wastethat are harmful to the hospital environment and the surrounding community if the disposal isnot treated before discharge into the water streams, thus it is important to monitoring andhandling in the hospital environment.This research is a descriptive study with the aim to describe the existing condition ofthe Waste Management System on Pulmonary Hospital at Surabaya. This research is useful tothe Hospital in order to improve their tunnel and immediately running the IPAL to reduce thelevels of pollutants and becomes the safe environment.The results of this study showed that the effluent liquid waste on Pulmonary Hospital atSurabaya has not been in compliance with the State Environmental Ministerial Decree ofRepublic Indonesia No : MEP - 58/MENLH/XIII/1995 because in the results of laboratoryexaminations was conducted on May 11, 2013 as the parameters of BOD, COD, TSS, and MPN,the coli bacteria/100 obtain a percentage of 134 ml mg/I, 237 mg/I, 20 mg/I and 9 x 10-8MPN/100 ml which is not considered feasible due to exceeding quality standards for liquidwaste Constanta to be dispose in water streams. Problems that exist in pulmonary hospitalsnowadays is the liquid waste treatment system due to discharge of liquid waste generated fromvarious sources is not running yet and it does not meet the capacity of the existing IPAL,irregularities found in the existing management system in a pulmonary hospital Surabaya, afterinvestigators traced by researchers there are some pipelines that leak or loss of liquid wastethat directly flows in drainage tunnels, and the sump apparently are not water resistant, and itcaused the water seep or seep into the ground.It is advisable for the pulmonary hospital at Surabaya to improve the liquid wastesystems, from the source to the hospitals liquid waste treatment such as repairing tunnels andfixing the sump. And the most important thing is to immediately run the existing IPAL inpulmonary hospital Surabaya so that the disposal of liquid waste can be reducing the levels ofpollutants and does not pollute or adversely affects the hospital environment or the localcommunity.Keywords: Liquid waste management systems, hospital liquid waste,PENDAHULUANLatar BelakangHospital liquid waste impacts.
