Abstract : Analysis Of Relationship Between Supporting The Observer Of Pulmonary Tb Treatment With Cured By Analitycal Epidemiological Studies. Pulmonary Tuberculosis is a communicable disease which are virulent and lethal. One of ten latent infections (hidden) will develop into active disease, which if not treated properly will be fatal for the patient. Most of TB patients can be recovered, if they meet the applicable provisions of the treatment. Epidemiological studies about relationship between supporting the observer of pulmonary tb treatment with cured in Puskesmas Purwodadi I Kabupaten Grobogan, prove not associated statistically. While in Puskesmas Mangkang Semarang Barat, shows there is significantly association between supporting the observer of pulmonary tb treatment with cured. The problem is which one of the finding be able to be the base of decision making in management of pulmonary TB program nationally. The purpose of this study was getting explanation and base of decision making, whether the finding in 2 puskesmas which produce different finding be able to be base of general decision making (inferensial). The epidemiological study used systematic review methods. Source of research data was from the literature, obtained through the Internet, relevant research, especially research in Puskesmas Purwodadi I Kabupaten Grobogan dan di Puskesmas Mangkang Semarang Barat. The result showed that epidemiological study in both Puskesmas Purwodadi I and Puskesmas Mangkang had some similiarity that were analytical, used chi–square test, and in the method of sampling (Non Probability). While in other study method was different, both in study design, number of sample, and the respondent's age criteria. Finding of epidemiological study in both Puskesmas Purwodadi I and Puskesmas Mangkang is inferential, so that only are specific site and does not apply to other population. Keywords : analitycal epidemiology, pulmonary-tb

Production of Biogas from Cow Manure and Chicken Manure with Addition of Papain. Farms not only contribute positively to meet the demands of protein and increase incomes but also have a negative impact on the environment due to their wastes, especially manure. Biogas produced from the anaerobic decomposition of organic waste is a solution of manure utilization to be a fuel which is cheap and environmentally friendly. To accelerate the production of biogas it is needed a proteoloitik enzyme from papaya, which is called papain. This study aims to calculate the production of biogas from cow manure and chicken manure with addition of papain. The experiments were conducted in the digester made from plastic drums and observed for 30 days. The results showed that the papain influenced of production acceleration of biogas from cow manure. Comparison of biogas production in a week from cow manure: cow manure + 2 kgs of papaya pieces: cow manure + 4 kgs of papaya pieces are 202.7 liters: 263 liters: 332.3 liters. Cow manure did not need other ingredients except water with ratio 1: 1½ . Chicken manure had not been able to produce biogas because their CN ratio was not eligible, although the chaff had been added to increase the carbon content. Biogas from cow manure with addition of papain can be applied on a wider scale, while biogas from chicken manure requires other ingredients that biodegrade easier to add C content in the mixture. Keywords : biogas; cow manure; chicken manure; papain

Ventilation is the process of exchanging clean air from outside into the room. Good ventilation is able to ensure smooth air circulation. This study aims to determine the relationship of air adequacy with comfort in room space. This research is an analytic study with cross sectional approach. The sample of this study was 30 rooms that used natural ventilation systems. The air change time is calculated from the volume of the room, the height and area of the ventilator, as well as the difference in the temperature of the outside and indoor air. Adequacy of air available with the air needed by its inhabitants. Objective comfort is based on the difference between outside and inside room temperature, and subjectively based on the room occupant's perspective. The results showed as many as 87% of the rooms had no air turnover time and as many as 20% of the rooms had insufficient air. Objectively stated rooms are uncomfortable as much as 57%, but subjectively reaching 77%. Statistically there is a significant relationship between air adequacy with comfort in the room objectively (p = 0.024). It can be concluded that the adequacy of the air represented by the ventilation system is related to the comfort of the air in the room space, to create a comfortable and healthy room space. Future research is expected to consider and include other factors that affect the ventilation system such as the layout of the furniture, the position of the ventilation, and the characteristics of the building so that research on comfort is more objective.

Abstract: The Influence Of The Distance Of Pollutant Source On Sulfate (So4) Concentrations In The Dust Along The Coal Haul Road. One of the quality parameters of coal is Sulfur. Sulfur content in coal be able to reach 4%. Sulfur content in coal at South Kalimantan mine ranges from 0.08 – 1.58%. Sulfur can be in the form of pyrite as S2 and sulfate as SO4. Sulfur content in coal dust that floats in the air will fall along with rain. This study aims to determine the effect of distance to SO4 levels on dust along coal haul roads. The sampling point was taken from variation of distance that is 1 m, 50 m, 100 m, 150 m, and 200 m from the side of coal haul road. The results showed that the highest sulfate concentration was at 1 m distance from the side of the road, that was 37.865 mg/L, and the lowest was at 200 m distance from the side of the road, that was 3.405 mg/L. These sulfate concentrations were proportional to dust fall. The farther the sampling point, the sulfate content decreases. Keywords: Dust Fall; sulfate concentration; distance.

Abstract: The Neutralization Process of pH on Peat Water in Desa Sawahan Kecamatan Cerbon Kabupaten Barito Kuala. Desa Sawahan, Kecamatan Cerbon, Kabupaten Barito Kuala, located in the area of peatlands with a pH of water, based on laboratory results, is 3.0. This condition is classified as extreme acid, because pH less than 3.5. Neutralization of the peat water aimed to change the pH or acidity of the water to be normal (pH 7-8) and could help the next process. To raise the pH of acidic water, quicklime (CaO) or limestone (CaCO3) was very appropriate, because they were cheap and easy to be applied. This study is experimental, the laboratory-scale trials with variations: the concentration of solubility of lime and jartest, to obtain the optimum dose of coagulant for improving the quality of pH. Results of the experiments on the variation of the solubility of limestone with varying concentrations showed relatively similar results, ie at a concentration of 1.0%, the pH of the water became 12.49; at a concentration of 0.5%, the pH of the water became 12.47, and at a concentration of 0.1%, the pH of the water became 12.18. In the next test, the addition of lime solution with a concentration of 0.5% as much as 9 mL in 500 mL peat water sample were able to raise the pH from 4.06 to 7.77. Jar test results showed that the injection of 5 mL solution of lime and alum 2 mL were able to raise the pH of peat water from 4.02 to be 7.24 so as to meet the requirements of drinking water with pH 6.5-8.5. To neutralize the peat water with a pH of 4 is required optimum dose of lime solution with a concentration of 0.5% as much as 5 mL (50 mg/L) and alum solution with a concentration of 0.5% as much as 2 mL (20 mg/L). Keywords: Neutralization of pH; peat water; jartest.

The amount of Fe in groundwater is usually quite high and causes the water to turn yellow-brown in color. According to preliminary test results, Fe levels were 4.62 mg/L and pH was 4.3 in one of the drilled wells in Banjarbaru, which did not fulfill quality criteria. Using zeolit and cassava peel to enhance Fe levels can be taken as an option. The aim of this study was to determine the effectiveness of the combination of zeolite and cassava peel in improving Fe and pH levels in a drilled water well. An experiment with a post-test only control group design was used for this study. The research population was the entire water supply from one of Banjarbaru’s drilled wells. The research sample was drilled well water, which was taken in part for testing. The Kruskal-Wallis test was employed to analyze differences in Fe levels, followed by the Mann Whitney test with a p-value < 0.05, indicating that there is a significant difference in Fe levels after treatment with combinations A, B, and C. According to the study’s findings, combinations C were the most effective in increasing the Fe levels and pH of drilled well water by up to 0.91 mg/L (78.32%) and 7.2.

Today, many houses are located on the edge of highways, potentially exposing these homes to additional noise from the traffic flow. This study aims to determine the relationship between noise levels and the comfort levels of residential homes in the Bangkal sub-district. This observational study, which has a cross-sectional design, includes 12 sample points for noise measurement and 77 houses directly adjacent to the road for comfort level sampling. Noise levels were measured using a sound level meter, while traffic density was measured using a compass and counter. The relationship between the two variables was analyzed using the Spearman correlation test. Results showed that the volume of traffic flow ranged from 334 pcu/hour to 402 pcu/hour. The highest noise level was recorded at TS-7 (65.7 dBA) and the lowest at TS-9 (61.7 dBA). According to the South Kalimantan governor's regulation number 53 of 2007, all 12 sample points of noise measurement exceed the quality standard. The average correlation between noise level and comfort level indicated that 88% of households reported being less comfortable, 12% felt uncomfortable, and none felt comfortable. Houses can reduce road traffic noise by installing thick curtains on their windows and doors, planting trees and ornamental plants in pots, and constructing artificial walls.

Domestic wastewater can be defined as water that comes from human activities and contains various types of harmful pollutants, such as TSS. Direct discharge of these pollutants into water-receiving bodies can cause pollution of aquatic ecosystems. Therefore, it must be treated to meet the appropriate air quality standards before being discharged to the air-receiving body. This study aims to determine the effect of pH on the efficiency of domestic wastewater treatment using mineral water plastic bottle caps with an anaerobic biofilter method. The study was conducted using an experimental method in two anaerobic biofilter reactors, with variations in the number of treatments of 100 and 300 bottles of bottle cap media and contact times for 0 days and 4 days, respectively. Anaerobic biofilter research results show that pH influences the efficiency of domestic wastewater treatment with mineral water plastic bottle caps in accordance with quality standards. The optimum pollutant removal value was found at a contact time of 4 days, which was 46% on 300 pieces of media. The use of a biofilter with a plastic bottle cap media can be an alternative to treating organic wastewater that has a low load, such as household wastewater. Further research can be done by adding more pores in the bottle cap media to improve the performance of the biofilter, as well as increasing the contact time variation treatment and the amount of bottle cap media used.

Noise is the sound of an inappropriate place and time. Workplace noise problems are a source of stress that causes psychological imbalances. Sources of noise in the workplace come from operating machines, such as sand mines in Cempaka and Banjarbaru, which contribute to workplace noise. Sand mines use diesel engines; the engine sound is loud enough that all workers in the mine are exposed to the noise. Workers who are exposed to high-intensity noise experience work stress. The study aimed to determine the relationship between noise exposure and work stress among sand mining workers in Banjarbaru. This observational-analytic study used a cross-sectional design. Observations were made on 25 workers who were exposed to noise. The data were analyzed using the Pearson correlation test. The results of noise measurements in sand mines ranged from 72.1 dBA to 88 dBA, with noise exposure for each worker ranging from 65.5 dBA to 83.7 dBA and work stress scores ranging from 34.12% to 50.7%. Statistically, there is an association between noise exposure and work stress. It is recommended to check the diesel engine, lubricate it to reduce noise in old and poorly maintained engines, use ear protection devices, such as ear plugs and ear muffs, to reduce noise exposure, and rotate every job task, especially for workers around diesel engines.
