PT. Coca-Cola Amatil Indonesia Central Java is a company producing soft drinks. Based on the data of liquid waste quality checks in December 2016 showed that phosphate (PO4) level of 2.708 mg / l is still above the standard of 2 mg / l. The purpose of this study is to determine the performance of waste water treatment system PT. Coca-Cola Amatil Indonesia Central Java is viewed from 5 aspects, the operational techniques, institutional, financing, regulation and community participation as well as knowing the influence of lime solution in lowering the liquid phosphate content. The method used in this research is descriptive qualitative and quantitative method with design of quasi-experimental research. The sample used in this research are 4 employees of waste water treatment PT. Coca-Cola Amatil Indonesia and liquid waste PT. Coca-Cola Amatil Indonesia for experimental application of lime for 4 replications and analyzed using Krusskal Wallis and Mann Whitney analysis methods. The results showed effluent of liquid waste produced by PT. Coca-Cola Amatil Indonesia smelly, murky and dirty and the absence of environmental health experts in the processing of liquid waste, most of them are graduates of mechanical engineering graduates. There is influence of lime solution of various variations on the decrease of phosphate content of PT. Coca-Cola Amatil Indonesia (p-value <0,05 ie 0,001), with effective dose 5 ml and efficacy 83,66%.

Benzene (C6H6) is a compound produced from petroleum distillation process. Workers in the laboratories of petroleum revinery unit industry are individuals at risk due to exposure to benzene. The purpose of this research is to estimate the health risks of benzene exposures mainly via inhalation in continuous time. This research did at laboratory of PT. Pertamina RU IV Cilacap. This research was descriptive research with environmental health risks analysis method. Total sample were 51 respondents. Benzene concentration measurements was at 8 points in laboratory. The anthropometric characteristics include weight gain, long exposure, exposure frequency, and duration of exposure. The measures include the analysis of hazard identification, dose-response analysis, exposure analysis, risk characteristics, and risk management. The results of the average concentration of benzene from 8 point was 0,287 mg/m3. The average yield intake of all workers on non-carcinogenic effects was 0.0027 mg/kg/day. The average of workers intakes of carcinogenic effect was 0.0039 mg/kg/day. A total of 19 respondents (37.35) had risk of non-carcinogenic effects (because RQ> 1) in realtime exposure and 100% were risk on lifetime exposure. At the carcinogenic effects 20 respondents (39.2%) had a risk of carcinogenic effect (because ECR>10-4) in realtime exposure and 100% were risk on lifetime exposure. Levels of benzene in the air environment of the lab in 2016 may lead to non- cancer health risks and cancer . It is necessary to risk management by reducing the concentration of benzene , reducing the length of exposure , reducing the frequency of exposure , or reducing the duration of exposure.

Babon River is a river that flows in the Genuk industries region and has decreased water quality due to contaminated residential waste and industrial waste. The industry includes coal heap, garment industry, leather tanning industry, light brick industry, plastic industry, and industrial ice cubes. This research aims to determine the lead content in the sediments and biota Sulcospira testudinaria along the Babon river from the mouth to the dam of Pucang Gading. This research was a descriptive observational research with quantitative approach. The results of supporting variable are water temperature 260C-280C, water pH 6, dissolved oxygen 2,2 mg/l – 3,6 mg/l, the salinity of fresh water from 0,20/00 – 0,60/00, Salinity brackish water 300/00 reseacrh sites. Analysis of water quality data is using Pollution Index. The result of using AAS is obtained levels of lead sediments in Babon river is the highest for 7,256 mg/kg and the lowest is 4,170 mg/kg. Levels of lead heavy metals Sulcospira testudinaria biota is the highest 2,403 mg/kg and the lowest is 1,8 mg/kg. The pollution index was lightly polluted with the amount of 1,96 which was the highest in Penggaron Kidul and the lowest is 1,13 in border between Banjardowo and Trimulyo. It can be concluded lead in sediments does not exceed the quality standards Sediment Quality Guideline 2003, while levels of lead heavy metals Sulcospira testudinaria biota has exceeded food quality standard SNI 7387:2009.

Laundry business is a business in clothes washing services. Preliminary test results show that the levels of phosphate and COD laundry liquid wastes is 12,36 mg/l and 5.920 mg/l. These levels exceeded the water quality standard of waste that phosphate concentration of 2 mg/l and COD concentration of 100 mg/l. This research aimed to determine the difference effectiveness of zeolite and manganese greensand to decrease phosphate and chemical oxygen demand on waste "laundry zone" in Tembalang. This research uses Quasi-Experimental with pretest - posttest design. The sample used is wastewater from the washing machine outlet of "laundry Zone". Analysis data used to test hypothesis is by one way anova test with 95% significance level. Research result show that phosphate levels before treatment is 12,36 mg/l and COD levels is 5.920 mg/l. After treatment with zeolite and manganese greensand in diameter 0,25 mm, 0,5 mm, 0,75 mm and 1 mm showed that the levels of phosphate and COD decreased. From one way anova got the difference at significant of α = 0,05 decreased levels of phosphate and COD after media zeolite by p-value = 0,001, the difference at significant of α = 0,05 decreased levels of phosphate and COD after media manganese greensand by p-value = 0,01, and the difference at significant of α = 0,05 decreased levels of phosphate and COD after media zeolit and manganese greensand by p-value = 0,0001. Effectiveness of the highest decline in phosphate and COD reached 73,30 % dan 71,68% occurred in treatment with zeolite diameter of 0,25 mm.

Transport is a major source of air pollution. PM10 is a pollutant which is a health predictor and can cause vital pulmonary damage. Terminal is one of the high locations of air pollution due to the activity of motor vehicles. This study aims to measure the level of air pollution and the relationship between inhaled dust levels and vital capacity of lung at Semarang City Terminal. The type of research is observational analytic research with cross sectional approach. The population in this study is the air in Semarang City Terminal and 76 traders. The sample of this research is PM10 at 1 point on the three terminals with the number of respondents as many as 30 traders using purposive random sampling. The results of laboratory PM10 ambient air in Semarang City terminal is in the range 38.39 - 99.35 μg/m3 and the inhaled dust levels of traders are in the range 0.83 - 3.33 mg/m3. Measuring the pulmonary vital instrument of traders shows the normal results of 13 traders and 17 traders are not normal. The results of the research with Chi Square test showed that the association of inhaled dust content with vital capacity of lung (p = 0,024) and the presence of inhaled dust levels exceeding NAB (3 mg / m3) was an abnormal lung vital capacity risk factor (RP = 2.18) . The air quality in Semarang City Terminal is in good and medium category and there is correlation of inhaled dust level with vital capacity of lung at permanent traders at Semarang City Terminal.
