Abstract

Collection and transportation of waste in the Distiict of East Denpasar have not run optimally due to lack of garbage collection and waste transport processes which are 1101 adequate. The research was conducted with a S\1tvey to determine the condition of existing operational waste transportation route followed by following the waste transport vehicles and calculate the time it takes to make one trip transportation and the number of trips in one day. The number of vehicles Uiat will be surveyed in the field is the number of vehicles that serve the Sef'\????ce area of East Dcnpasar DistJ·ict, which consists of dump trucks and arm roll truck. The results showed that the waste transportation operations in the District of East Denpasar have not nm optimally due to lack of bins for the community and a fleet of garbage that is not proportional to the volume of waste generated, the number of transport trip has not been able to reduce the waste. Transport route selection is currently not effective because it ha???? not minimized the di????-tance and travel time. The condition of access to TPA Sarbagita is unfit to be passed by a garbage truck, where the bumpy road conditions can cause damage and inhibit the rate of truck components.

Abstract

Installation of water treatment is the required infrastructure in meeting the needs of clean water. During the process of water treatment it produces waste water as a byproduct that could potentially cause pollution if not properly treated. The research purposes of the study are to determine the effectiveness of compliance procedures for waste water treatment, the quality and quantity of waste water and its impact to the environment, as well as providing alternatives for waste water management strategies. Determination of samples were conducted by using purposive sampling method. Samples were taken at two sewer sedimentation and filtration points antl the other four points were taken in the water body and then compared with Governor of Bali Regulation No.8 year 2007. Samples were analywd both in situ and in the laboratory. To determine the effectiveness of the waste water treatment to the conformity assessment procedures, the field conditions were analyzed with a force-field analysis. The effectiveness of waste water management was categorized as moderate. The quality of waste water from the sedimentation basin shows the parameters of TSS (4957.50 mg/I) and Mn (81.68 mg/I), of the tub filtration TSS (665 mg/I) and Mn (12.60 mg/I). The quantity of waste sedimentation basin discharge (Q) o.68 mg/sec, TSS pollutant load (3371.01 mg/sec), Mn (55.51 mg/sec), filtration basin discharge (Q) o.68 mg/sec, load TSS pollutant (332.50 mg/sec), Mn (6.30 mg/sec). Based on the force-field analysis conducted, some alternative strategies were proposed such as building facilities for waste management, environmental m.inagement implementation based on the appropriate planning, implementation of waste water disposal permit including fulfill the technical conditions as required, technical capacity building of human resources, and land use.

The use of fertilizer, farm and household cesspool disposal, and changes of land function can reduce the quality of the water. This research is done in order to know the quality of water and index of its pollution. This research is done in Telaga Waja river for along 10 kilometres from Besakih Village to Muncan Village from August until November 2011. The research of physic parachmeter, chemistry and microbiology by taking sample for insitu and eksitu examination are compared with the standard quality of Balinese Goverment Regulation No.8/2007. While the observation and interview are done in order to know beha,1our of the people in polluting the water. Result of the research shows that the concentration of Fecal coli and Total coliforms reach 240.000.000 MPN/100 ml It is more than standard quality of all classes.The analysis of COD is more than first class water quality, BOD and Fosfat are more than third class water quality and DO concentration is less than minimum first class water concentration. The evaluation of Pollution Index (Pl) for first class water in all location is high polluted. Evaluations PI of third and fou1th class standard water quality in Menanga Village and Muncan Village are medium polluted and from Rendang Village until Muncan Village is high polluted in the delta of the river. Water condition indicate function ofTelaga Waja watershed for agriculture, living place, tourism ( rafting, restaurant, and villa), and mining pollute the water. Base on the evaluation of pollution index, all locations are medium and high polluted. That is why the goverment, entrepreneurs, and the society should save River Telaga Waja by keeping it clean. Observation of the water quality is also should be done regularly.

Abstract

The grain grinding business unit is needed by the farmer to process the harvest but also in particular, it creates air pollution from its dusty materials. The worker or operator has a potential risk of being contaminated by the dusty materials and lungs vital capacity reduction. This research is aimed to analyze the effects of the grain grinding polluting dust to wards the lungs vital capacity of workers at Abiansemal in Badung District. This research is sort of an analytical observation with cross sectional design. The number of chosen samples is 32 workers with a total sampling method among 16 grain grinding business units. The data resources is a primary data which obtained using questionnaire, the measurement and observation include: the worker's characteristic (working term, age, and height), dust value, breath frequency and lungs vital capacity. The data is analyzed using regression statistic. The result of the research indicates that the amount of dust at the grain grinding business unit is around 10,0079-11,6151 mg/m3, working term is one to 44 years, age 22-62, and height 155-175 cm, the condition of the grinding room is 93,75% does not meet the ventilation standard, 100% is not provided with dust control tool, 97,75% does not provide mask and 93,75% is situated in a housing are. The conclusion of the research is that dust level, working term and height in particular has a significant correlation with lungs vital capacity (p < 0,05) but age does not have a significant correlation with the workers lungs vital capacity (p> 0,05). The higher level of dust makes the higher lungs vital capacity reduction, the longer working term makes the lower lungs vital capacity and the taller of workers height .indicates the higher workers lungs vital capacity. The impact of dusty materials of grain grinding business unit towards the workers is the decreasing of workers lungs vital capacity by the disorder of lungs restriction function ( 65,62%). It is suggested to the business owner to conduct technical controls. Workers are strongly recommended to put on mask, have sufficient nutrition supplies and workers with the age over 40 years should not work in j:his area. For the health department of Badung District should implement any efforts of K3, and for other relevant departments which take a part in giving recommendation must consider a requirement to make it outside the housing area.

Abstract

Based on the data of Environmental Status of Bali Province Year 2009, Sungi River is the one of ten rivers that have experience quality degradation which contaminated by waste. Pollution parameters that have exc.eeded the quality standard, are: BOD, COD, Total Phosphate, Total Coliform, and Faecal Coliform. It requires to concerned because Sungi River as the point area for drinking water in Tabanan (data of Environmental Board of Bali Province). Purpose of research is to determine the characteristic of pollution source which will be impact to the changing of water quality in physical, chemical, and biological in middle and down stream area, detern1ine the pollution index in up stream, middle. and dow stream area of Sungi River. Water parameters that will observe are: temperature, pH, turbidity, TDS, TSS, DHL, DO, BOD, COD, Total Phosphate, Total Coliform and Faecal Coliform. The measurement result will compare with the best of water quality, based on the Regulation of Bali Governor Number 8 Year 2007, because of it utilization as drinking water. Result of research shown that the activity in Sungi River dominated by agriculture activity, settlement, animal husbandry, and industry that located in dov.n stream area. The waste that result from the above activities caused the degradation of water quality that shown by the increasing of water parameter indicators, such as: BOD, COD, Total Phosphate, and Faecal Coliform Bacteria. In the middle will increasing and down stream area will get degradation. This condition is inversely proportional to the content of DO as impact of contaminants accumulation, such as: organic waste in middle are, because the water movement is more calm with average water flow is 0,14 m/second compared with the up and down stream area with average water flow are 0,15 m/second and 0,35 m/second. Characteristic of pollution source which effect the water quality at Sungi River in area I caused by llie activities of agriculture, animal husbandry, settlement, and industry, for area II caused by the activities of agriculture, animal husbandry, settlement, and villa. The quality staLus of Sungi Rlver in up stream area still result a good quality water but in the middle and down stream area are get lightly pollution. Water quality parameter which exceeded a good water quality in Sw1gi Rive,· is Total Phosphate with average value is 0,44 mg/I in the middle area, 0,40 mg/l in down stream area and Faecal Coliform with average value is 166/100 ml in the middle area and 152/100 ml in the down stream area.

Abstract

Regional Ocean Modelling System (ROMS) has been intended to be a multi-purpose, multi-disciplinary oceanic modeling tool. The Biogeochemical model have coupled to ROMS consists of a system of seven coupled partial differential equations that include: nitrate, ammonium, small and large detritus, phytoplanJ..'ton, zooplankton, and a dynamic phytoplanJ..-ton carbon to chlorophyll ratio. The study of distribution patterns of chlorophyll-a in Lombok Strait (-7 °N - ·10 •sand 114 "E - 117 °E) in 2006 was analyzed using the Biogeochemical model based on ROMS. The results show that low chlorophyll-a distributions (0.20 mgChl-a/m3) observed in Lombok Strait in ,January. Chlorophyll-a estimated around the southern part of Bali Strait and low chlorophyll-a distribution in upper layer of the Lomhok Strait. Chlorophyll-a of the booming (0.32 mgChl-a/m3) observed in August. The northeast current direction moves to the west and southern part of research area through Lombok Strait. The highest chlorophyll-a concentration estimated in the northern and southwestern part of Bali Tsland and also in the southern part of Lombok Island. During dry monsoon, southeasterly wind blow from Australia generates upwelling process (low temperature and nutrient-rich water near the surface) also estimated from ROMS.

Abstract

Garbage Dump (GD) of Temesi which is located at Temesi village within 6.5 km south east of Gianyar city, which is geographically located at a point 8°33 south latitude and 115Q east longitude with an altitude ± 191 - ± 196 meters above sea level. The area of GD of Temesi about 4 ha, by limitation; North: field rice and population residences; East: field rice; South: field rice and West: field rice. GD of Temesi Gianyar has been collecting garbage about 198.52 m2 /day. GD of Temesi operates with open dumping, so that the leachate from garbage to pollute the enviorment and shallow ground water around the GD. This study ms conducted to know the direction of seepage and location of point accumulation of leachate at GD of Temesi Gainyar. This study was conducted with measuring soil layer values at GD of Temesi Gianyar, was taken eight tracks measurement. The method used in this study by using the geoelectric resistivity with Wenner configuration and Schlumberger configuration. The eight tracks are taken represent the overall of the soil layer condition in GD of Temesi Gianyar. The result of study showed that the tracks 1st, 2nd, 3rd, 4th, 5th, 6th, and ih was indicated that leachate seep on area in each tracks, however, in 8th tracks was not identified of leachate (8th tracks is located far from the GD and it's contours are higher than the tracks of garbage). Value of leachate resistivity ranged from 3.98 - 8.91 nm with a depth ranging from 1.55 - 6.91 meters. Most of leachate spread to southward of GD as far as more than 400 meters. Accumulated of leachate widely available at a distance of 20, 50, and 400 meters to the south of the GD of Temesi. The main factor is the south of the GD has a lower contour. Another factor affecting the leachate seeped into the south is the present of some field irrigation water from north to south across a stack of garbage.
