Abstract

Abstrak : Changing the Threat of tofu Wastewater Hazardous to be Economical Oppurtunities. Wastewater from Tahu industry known as “whey” are offensive and be able to cause negative impact to the environment. This problem is caused by the characteristic of whey which is hot, acid, and containing much organic material. Because of this characteristic, their dissolve oxygen is also zero ppm. Measurement of tahu and tempe wastewater in Semanan, Jakarta Barat showed that the whey contains 1.324 mg/l of BOD5, 6.698 mg/l of COD, 84,4 mg/l of NH4, 1,76 mg/l of nitrate and 0,17 mg/l of nitrite 1). The potential hazard of whey to aquatic life can be measured by counting the concentration of whey’s parameter which be able to cause the death of tilapia (LC50), that is from 3,80% up to 11,5% at 24 hours exposure; 3,67% up to 14,30% at 72 hours exposure; and 3,38% up to 12,10% at 72 hours exposure 2). On the other hand, Acetobacter can change sugar to be vinegar, with byproduct is film coat “nata” floating. Factors influencing Acetobacter growth are sources of Carbon and Nitrogen. Appropriate nutrient content will produce “rendemen nata” (de coco) maximum, that is up to 93,3% 3). This study aims to know does the whey which is added by Acetobacter xylinum can produce nata de soya?. The result gave information that if into the whey added the Acetobacter (made from ripe pineapple) as a starter, and urea in acidic condition, would produce rendemen nata approximately 30%–40%. 4). Keywords: wastewater of tahu industry; nata de soya of whey

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 respondents 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

Abstract

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

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.

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 Comparison Of Emission Levels Of Carbon Monoxide Exhaust Gas In Automatic Motor Vehicle Injection System. Transportation plays a very big role as a source of air pollution, especially exhaust emissions reach 60-70%. CO emitted by motor vehicle which exceed the standard be able to cause disturbance and even death. The development of a two-stroke engine vehicle into a four-step engine is a people demand who want a vehicle which is easy and comfortable. Indonesia has many different types of vehicles, but two types of motor vehicles with the YMJET-FI and PGM-FI system are most on the market. Three fuels such as premium, pertalite and pertamax are used by the public. This research was observational analytic, using Posttest Only Design to analyze the CO emission from YMJET-FI and PGM-FI engine with premium fuel, pertalite and pertamax. CO emission was tested at engine speed of 1.900-2.000 rpm and temperature 80oC. Analysis used Two Way Analysis of Variance statistic test with α = 0,05%. The results showed that YMJET FI using premium emitted CO as 0,23%, pertalite 0,32% and pertamax 0,37%. PGM-FI using premium emitted 0,21% , pertalite 0,24% and pertamax 0,25%. The conclussion is, both of YMJET-FI and PGM-FI, using premium, pertalite and pertamax emitted CO lower than the emission quality standard according to KemenLH 2009 such as of 4,5%.
