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

RELATIONSHIP HOUSING SANITATION WITH TUBERCULOSIS DISEASES (TB) INCIDENCE IN KUTA DISTRICTOne of the endemic infectious diseases occured in the community is tuberculosis (TB). The World Health Organization (WHO) estimated about one third of the world's population has been infected by the bacteria mycobacterium tuberculosis. Badung regency as one of the districts in the province of Bali also having cases of tuberculosis. From the report Badung Health Agency in 2015 was recorded 275 TB patients. From 6 districts in Badung district, subdistrict of Kuta occupy the highest number of cases recorded 100 patients. tuberculosis is closely related to homes sanitation that do not meet health requirements. The purpose of this study was to determine the relationship of home sanitation with disease incidence of tuberculosis in the district of Kuta. Based on the type of research is observational analytic, design research is a case control studies linking ie risk factors. (Home sanitation) with TB disease events, by comparing the case group and the control group. The population in this study are patients with TB BTA (+) were treated working area Puskesmas Kuta I and Puskesmas Kuta II sanitation as well as his home. The number of samples in this study was 60 consisting of the case group and the control group. How sampling is the total population of TB patients in the last 3 months of 2015 as well as sanitary home. Data collected from interviews, observations and measurements and then analyzed using chi square and followed by multiple logistic regression test. From the statistic test bivariate home sanitation  with tuberculosis disease incidence 6 variables showed that: (1) lighting p = 0,00 (p< 0,05) OR = 21, (2) humidity p = 0,00 (p< 0,05) OR = 21,36 , (3) ventilation p = 0,00 (p< 0,05)OR = 11, (4) the walls of the house p = 0,00 (p< 0,05) OR = 8,64, (5) density residential home p = 0,00 (p<0,05) OR = 16,43 and (6) house floor p = 0,22 (p>0,05) OR = 2,143. To determine the relationship of all independent variables simultaneously multivariate analysis with multiple logistic regression test. Based on the results obtained that there are three independent variables significantly related (p<0,05) with the dependent variable is the humidity (OR = 19,158, 95% CI 3,171 ?115,751), ventilation (OR = 6,408, 95% CI = 1,199 to 34,236), residential density (OR = 13,342, 95% CI = 2,261 ? 78,733). Probability of people who occupy the house with sanitation (Humidity, Ventilation and Residential density) in the district of Kuta to contract tuberculosis (TB) is 97,08%. Based on these results, we can conclude that from the test bivariate (6 variables) are: lighting, humidity, ventilation, walls of houses, residential density and house floor associated with the incidence of tuberculosis in the district of Kuta. While the advice may be given to: (1). people who live in the district of Kuta in order to build or occupy a dwelling house to take into account the standard of sanitation and healthy home. (2). Government / agencies in order to provide guidance to the public in order to build houses of spatial attention and care homes that meet health requirements so that people who lived in the house to feel safe, comfortable, and avoid the disease especially those stemming from poor sanitation home.

Abstract

Air merupakan salah satu kebutuhan dasar yang sangat penting bagi manusia. Terdapat beberapa faktor utama penyebab perubahan sumber daya air, diantaranya adalah perubahan penutupandan pengelolaan lahan yang meningkatkan kekedapan lahan.Salah satu tujuan pengelolaan DAS adalah mencapai kondisi tata air optimal yang dapat dikenali dari sifat aliran sungai. Penelitian ini bertujuan untuk: (1) mengetahui distribusi perubahan penggunaan lahan yang terjadi di wilayah DAS Cisadane Hulu dari tahun 2003 sampai 2010; (2) mengetahui perubahan hasil air akibat distribusi perubahan penggunaan lahan. Daerah kajian penelitian adalah DAS Cisadane Hulu dengan luasan sekitar 22.288,01 ha. Penelitian dilakukan melalui dua tahap yaitu analisis perubahan penggnaan lahan dan prediksi aliran dengan model HEC-HMS. Dalam penelitian ini digunakan peta pengunaan lahan dari BIG (Badan Informasi Geospasial) tahun 2003 dan Peta Penggunaan Lahan tahun 2010 hasil interpretasi Citra ALOS. Selanjutnya kedua peta tersebut dianalisis dengan metoda tabel silang (cross tabel) untuk memperoleh data perubahan penggunaan lahan dari setiap kelas penggunaannya. Kedua data series penggunaan lahan ini digunakan sebagai input pada model prediksi debit aliran HEC-HMS. Selanjutnya dibangun juga skenario-skenario untuk melihat dampak perubahan lahan terhadap debit aliran di DAS Cisadane Hulu. Metode bilangan kurva (SCS-CN) dipilih untuk menghitung besar curah hujan efektif, yaitu dari pengurangan curah hujan bruto dengan berbagai bentuk kehilangan air (loss). Transformasi dari curah hujan efektif menjadi hidrograf aliran langsung (direct runoff) diperoleh dengan menggunakan metode hidrograf satuan SCS Curve Number. Selama kurun waktu 2003 ? 2010 terjadi perubahan penggunaan lahan di DAS Cisadane Hulu. Luas Hutan bertambah 223,78 ha, pemukiman 214,78 ha, rumput/tanah kosong 85, 73 ha, dan gedung 12, 64 ha. Terjadi penguarangan luas semak belukar 225,64 ha, tegalan/ladang 145,92 ha, sawah irigasi 124, 92 ha, sawah tadah hujan 30,67 ha, dan kebun/perkebunan 9,92 ha. Hasil dari simulasi dengan menggunakan peta penggunaan lahan tahun 2010 didapatkan nilai debit puncak (Qp) sebesar 81.73 m3/detik. Nilai volume puncak (Vp) sebesar 2,310.7 mm dan Waktu Puncak (Tp) pada hidrograf aliran yang dihasilkan model terjadi pada tanggal 26 Maret 2010. Secara umum terjadi peningkatan debit puncak antara penggunaan lahan tahun 2003 dengan 2010. dari 81.22 m³/detik menjadi 81.73 m³/detik. Naiknya debit puncak disebabkan meningkatnya aliran permukaan akibat perkembangan pemukiman di DAS.Hal ini terlihat dengan meningkatnya nilai CN rata-rata dari 38.5 menjadi 39.4.Pada simulasi dengan penggunaan lahan tahun 2010 didapatkan hasil airsebesar 2.310,7 mm/tahun.Nilai ini lebih kecil dari simulasi dengan penggunaan lahan tahun 2003 yaitu 2.320,1 mm/tahun. Salah satu penyebab berkurangnya hasil air dapat dikarenakan penguapan yang meningkat akibat bertambahnya luasan hutan. (banyaknya pemanfaat air tanah disekitar DAS tersebut, baik legal maupun ilegal).

Abstract

The people's gold mining and processing activities have an impact on the surrounding environment. Some residents immediately dispose of waste from gold processing into the environment. Therefore, analysis of the level of vulnerability of pollution is needed to determine the size of the level of difficulty and ease of contaminated substances to influence water quality, both surface water and groundwater. The purpose of this study was to analyze the level of vulnerability of groundwater pollution around the study area. The method used in this research is survey method and field mapping, sampling method: purposive sampling, laboratory analysis method, mathematical method, and descriptive evaluation method. The calculation to determine the level of vulnerability of pollution is the DRASTIC method for groundwater vulnerability with 7 parameters, namely groundwater depth, rainfall, aquifer type, soil texture, slope, slope, unsaturated zone type, and hydraulic conductivity. Based on the results of the study it was known that the study area had 2 classifications of the level of vulnerability of groundwater pollution, namely the moderate and high classification. Areas that are located in the direction of groundwater flow and are lower than pollutant sources will potentially be more polluted.   Keywords : DRASTIC, Pollution, Groundwater, Gold Mine

Abstract

Fungi in the soil plays an important role in maintaining the health and quality ofland, one of several indicators of soil health that is the diversity of soil fungi. This study was done in order to know the soil fungi diversity in the soil of banana plants habitat. The soil samples were collected from three regencies in Bali, i.e. Karangasem, Klungkung and Jembrana which are the main banana growing areas in Bali. Soil sampling was done in two sites in each regency, by collecting 100 grams of soil surrounding the banana plant at the depth of 20 cm, with three replication. Soil microbes population density particularly for bacteria, fungi and actinomycetes were determined based on plate account technique, while the microbes diversity was determined based on Diversity Index of Shannon-Wiener. Diversity index of soil fungi of all soil samples ranged from 0.8785 to 2.1458 (criteria oflow to moderate), with population densities ranging from 1.1 x 104 to 2.8 x 104 cfu / g soil. Evenness index at all sites soil samples obtained ranged from 0.6688 to 0.9766, this means the fungus species found there are no outstanding domination. Similarity index on all soil samples showed less than 0.5, which means one does not have a kinship with each other. Physicochemical factors that affect population density of soil fungi on the banana plant habitats: organic C, total N, available P, available K, soil moisture content (air dry capacity and field capacity), sand and clay. W hile soil physicochemical factors that influence the number of species (diversity) of soil fungi namely: C-organic content, total N and the dust has positive influence on the number of species in banana plants habitat, whereas soil sand content negatively affected the number of types of soil fungi.

Abstract

Research has been conducted to determine the quality of shallow groundwater (dug-wells and shallow bore-wells) and the local communities opinions around the landfill Suwung. The method of determining the station was done by purposive sampling, where the station sampling was determined by selecting a place which was expected to represent the whole area.Water sampling of dug-wells was conducted by using a water sampler and the shallow bore-wells using a 2-liter bottle. Data was analyzed by descriptive comparative referenceto class I water quality of the Bali Governor Regulation No.8 of 2007. The public opinion data was obtained by using aquesioner filled by respondents who have and use wells and shallow bore wells for their daily needsand it was analyzed by using frequency distribution tables.The results showed that the quality of shallow groundwater (dug-wells and shallow bore-wells) did not meet water quality standards in accordance with the rules of the class defined in the Governor of Bali Regulation No. 8 of 2007. The water pollution index (PI) of dug-wells at a distance of 1-400 meters was in hearily polluted category, while water fromshallow bore-wells drilled at a distance of 1-200 meters was in the category of hearily polluted and at a distance of 201-400 meters was in the category of medium polluted.There was an increasing range of groundwater quality deterioration in 1997, 2008 and 2014. In 1997, contaminated shallow groundwater has occured at a distance of 80 meters, while in 2008, the pollution has occurred up to a distance of 375 meters and in the year of 2014 the contamination occurred from a distance of 1 meter to 400 meters. The average of score Pollution Index (PI) of Water wells in the year of 2008 amounted to 14.55, while in 2014 up to 15.44. It is estimated that the water quality of dug-wells and bore-wells will meet the quality standards in accordance with the value of the pollution index at a distance of over 5000 meters and 750 meters of the Suwung landfill waste.Most of the respondents who live in the vicinity Suwung landfill waste tend to give an opinion that the shallow groundwater (dug-wells and shallow bore-wells) has decreased quality as drinking water. Approximately 75% of respondents thought that the well water in their environment has been reduced in quality.

Abstract

This research aims to identify monitoring land subsidence in Semarang has been done using raster data operation of the DEM in GIS environment. Digital representation of relief of Semarang area was generated from a point map which contains elevation data. The last update of the elevation data was made using geodetic, using Global Positioning System (GPS). Decrease in land distribution is estimated from the data of GPS Geodetic years 2008-2011, in the Semarang area north, west, central, east and south. Reduction in the range of 2008-2009 reached -12.4 cm, then increased in 2009-2010 to be -20-4 cm and -10.5 cm fell back to the years 2010-2011. Decline in the face of the land in Hyderabad occurs mainly in the n01th, east, central and south of Semarang. Subsidence causing damage to infrastmcture, buildings, and results in moving tidal lowlands.damage potential economic loss is cracks in buildings and infrastmcture (roads and bridges), the number of homes that have been tilted and nearly drowned. In addition to direct losses, reduction in ground level also cause indirect losses that rob the increasingly widespread flooding in the northern region of Semarang.in 2008- 2010 June-July with a high tide occurs o.6 cm from the surface of the sea water in the area of Semarang.
