Abstract

ABSTRACT The production of pig manure waste potentially pollutes the soil, water and air. One of the most effective processing a waste treatments is through composting. The composting process takes a long time if not assisted by the activator as decomposers of organic materials in order to accelerate the composting process. Activators such as local microorganism (MOL) contain macro nutrients, micro and active microorganism that potentially decomposed organic materials, growth stimulants and pest/disease control agents such as to help speed up the composting process. This study aims to determine the C/N ratio of optimal raw materials for composting of pig manure and vegetable waste, determining the effect of adding local microorganism (MOL) to the length of time of composting and determining the effectiveness of business from composting of pig manure and vegetable waste based on the calculation of B/C ratio. This research uses quantitative approach with experiment method. The first stage is the preparation of the raw material which is divided into three groups : composition 1 with 75% (pig manure) and 25% (vegetable waste), composition 2 with 50% (pig manure) and 50% (vegetable waste) and then composition 3 with 25% (pig manure) and 75% (vegetable waste). Furthermore, the best raw material composition was treated with variations of MOL addition of A (100 ml), B (300 ml), C (500 ml) and D (without MOL). The results showed that the composition of the best raw material mixture was a mixture composition of 25% (pig manure) and 75% (vegetable waste) with a C/N ratio of 38.95. The effect of MOL addition indicates that the greater MOL volume the faster to composting process. The quality compost with addition of MOL has C/N ratio levels is (16,30), N-total (1,65%), P tersedia (8043,02 ppm), K tersedia (8857,40 ppm), Fe (1,87%), Mn (0,09%) Zn (480 ppm) in which that value meets the SNI 19-7030-2004. Based on analysis of B/C ratio obtained result of 1.04 where the value is approaching criteria B/C ratio more than 1.00 which means compost business feasible to be developed. Keywords : Pig manure, MOL, time of composting, composter, B/C ratio

Abstract

The development of marine transportation in Denpasar City followed by increasing number of visiting tourists who came to Denpasar City. This situation will contribute to air pollution problems. The purpose of this study was to determine the emission load produced by sea transportation in Denpasar City and the distribution of emissions gases such as NOx, SOx, HC, PM10, CO and CO2.Emission load calculations based on the guidelines of the EMEP Corinair Guidebook using Tier 3, which the emission factors used refer to the CORINAIR GB 2013 1.A.3.d. The results showed a total emission load from non-road mobile sources of marine transportation in the Denpasar city such as NOx is 14,583.69 tons/year, SOx by 85.49 tons/year, HC by 746.05 tons/year, PM10 at 503.53 tons/year, CO at 123,123.58 tons/year, and CO2 of 1,457,909.95 tons/year. Distribution of the source of pollutants mapped using GIS (Geographic Information System) shows that the emission load of NOx, SOx, HC and PM10 are likely identical, which mostly distributed around Benoa Port, but CO2 and CO have different patterns . The pattern of distribution of NOx, SOx, HC, and PM10 with the highest intensity follows the contours of the ships from Benoa Port. CO gas distribution pattern follows the contours of the ship from the Serangan Port and Sanur Port, CO2 gas distribution pattern almost evenly in almost all flow well from the Serangan Port, Sanur Port and Benoa Port

Abstract

Population growth followed by an increase in laundry activity generates waste if left unchecked will cause damage to aquatic biota. To overcome this need the existence of an environmentally benign laundry water treatment system such as biosystem. Biosystem used in this research with length 180 cm width 60 cm and height 40 cm filled gravel as filter media and elephant grass (pennisetum purpureum) plant. The way of operating the biosystem is by pouring the waste into a tub of biosystem and then samples waste water taken on the biosystem output. The result treatment that biosystems combined with anaerobic reservoirs decreased BOD, COD, phosphate and detergent levels by 127.09 mg/l, 161.96 mg/l, 0.8699 mg/l and 1.3228 mg/l in a single treatment on roughing horizontal flow filter for laundry water treatment. The performance of physical and biological components in biosystems combined with anaerobic reservoir effectively decreased BOD, COD, phosphate and detergent concentrations by 73.91%, 69.58%, 58.74% and 80.03% (above 50%) in one treatment. But only in lowering the effectiveness of phosphate levels is still relatively low when compared with the effectiveness of wastewater quality standards. Further research needs to be done calculations to find plants in biosystems that can thrive. In addition, further research is needed to find the operating time until the biosystem undergoes a breaktrough condition. Keywords: laundry, waste water, biosystem.

Abstract

Water quality management efforts need to be carried out in a sustainable manner to ensure that water resources are free from pollution. Water is an important component in human life, therefore the existence of water in nature must be maintained to ensure the continuity of human life. Decreasing water quality is caused by pollutant loads that enter water bodies due to human activities disposing of waste directly into the water. Batujai Reservoir is one of the vital objects for the survival of the people of Central Lombok. In an effort to control water pollution in the Batujai Reservoir, a model that is capable of managing Batujai Reservoir water is needed in a sustainable manner. The purpose of this research is to develop a model capable of managing the water in the Batujai Reservoir in a sustainable manner. The research methodology uses a quantitative approach using primary data from interviews with figures and experts as well as secondary data from literature studies and previous research data. Data analysis used the Interpretative Structural Modeling (ISM) approach. ISM is able to simplify complex relationships to be simple and form a hierarchy between existing relationships and be able to describe them in the form of system modeling. The results showed that the water pollution control model in Batujai Reservoir was carried out by involving all relevant stakeholders by placing academics, NGOs and Central Lombok Bappeda as the main drivers of program implementation and using the local wisdom approach.Keywords: pollution, control, water, model, batujai.

Abstract

Gajah Mada street is the main road in Denpasar to access traditional market in Badung and Kumbasari Market. It iscrowded street with many vehicles pass through it. As a result, this could increase the level of emission gas such asambient monoxide carbon gas which could affect the concentration of carboxyhemoglobin, exposure time and subjectivecomplaints of sample.his was a cross sectional study of 12 parking man. Data was mainly collected from measurements including thedensity of vehicles, vehicles type, oil fuel type, vehicle age, ambient monoxide carbon gas, carboxyhaemoglobin,exposure time and subjective complaints of sample.The study found that the average of vehicle density mean per day was 91.338 unit or 3.805,8 unit per hour (veryhigh). The biggest type of vehicle percentage was motorbike 81%, followed by vehicles using premium fuel 93,7%. Theage of vehicles below 10 years was 55%. The mean of monoxide carbon gases concentration was 585,96 ?g/m³ per day(mean). The mean of weather situation including humidity was 82,7%, temperature 27,6ºC, eastward wind direction, faircloudy an wind speed about 1,76 m/second. The average of carboxyhaemoglobin concentration in 12 parking man was3.8% (very low). The mean of exposure time was 125 minutes. It was noted that there were 9 samples (75%) withcomplaints and 3 samples (25%) without any complaints.The study concluded that the highest numbers or vehicle density it is very high categories. Monoxide carbon gasconcentration it is mean categories and was under threshold limit value. The highest numbers or vehicle density and Monoxide carbon gas concentration between 14.00-16.00 pm and. There was a significant correlation between vehicledensity and ambient monoxide carbon gas. The measurement of carboxyhaemoglobin concentration it is very lowcategories. It also found that the exposure time correlated with the level carboxyhaemoglobin of parking mansignificantly.It is suggested that the Government of Denpasar City should implement free parking area particularly in crowdedtraffic time, develop city garden and propose the community to use low fuel emission for vehicles.

Abstract

Oily waste can pollute environment. One of the method used to process the oily waste is aerationmethod. This researce is carried out by taking oily waste PT. Indonesia Power Business Unit Electric PowerStation Bali at Pasanggaran Denpasar, aimed at increase quality of the waste.The sampel used is waste of PT. Indonesia Power Electric Power Station Business Unit of Bali. Thesampel is intercepted and retained in a retaining box, and 11,12 litters are then taken to be put intotreatment tank. Aeration treatment duration given varies, such as 12 hours, 24 hours, 48 hours, and 72 hoursfor the sampel with air flow speed of 0,6m/s. The treatment is also done with adding sampel with mud of 1%of the whole sampel volume. The relation between Aerating duration with oil contents, oil layer, BOD value,COD value, TDS value and TSS value will be analyzed with simple correlation and descriptive analysis.Aeration treatment can reduce the contents of oil in waste and separate oil accumulated in the waterso that the oil can be depressed up. Aeration treatment can also lower BOD value, COD value, TDS valueand TSS value because giving oxygen in to waste will meet the needs of oxygen of disentanglingmicroorganism in the waste water and the needs of oxygen for oxidation of chemicals in the waste.Therefore, aeration treatment can increase quality of the waste.
