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

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

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.

Abstract

An algorithm was employed to retrieve the concentrations of three water constituents, chlorophyll-a,suspended matter and colored dissolved organic matter (CDOM) from MODIS (Moderate-ResolutionImaging Spectrometer) in wide range covering from oligotrophic case-1 to turbid case-2 waters at theBadung Strait Bali. The algorithm is a neural network (NN) which is used to parameterize the inverse of aradiative transfer model. It’s used in this study as a multiple nonlinear regression technique. The NN is a feedforward back propagation model with two hidden layers. The NN was trained with computed radiancecovering the range of chlorophyll-a from 0.001 to 64.0 ?g/l, inorganic suspended matter from 0.01 to 50.0mg/l, and CDOM absorption at 440nm from 0.001 to 5.0 m-1. Inputs to the NN are the radiance of the fivespectral channels which were under discussion for MODIS. The outputs are the three water constituentconcentrations. The NN algorithm was tested using in-situ data set on May, September, November 2005 atthe Badung Strait Bali and the north sea of Sumbawa Island and applied to MODIS. The coefficient ofdetermination (R2) between chlorophyll-a concentrations derived from simulation and in-situ data is 0.327,for suspended matter R2 is 0.408. No in-situ measurements of CDOM available for validation. Also, in-situdata were compared with the corresponding distribution obtained by the NASA standard OC4 (OC3M) forMODIS chlorophyll-a algorithm and giving R2 0.188. This study gives better accuracy compare withstandard algorithm. How ever both studies are giving over estimate chlorophyll-a concentration. Since thereare no standard MODIS products available for suspended matter and CDOM, the result of the retrieval by theNN for these two variables could only be assessed by a general knowledge of their concentrations anddistribution patterns

Abstract

Forest as an asset of national development is really beneficial for life and livelihood. It brings benefits ecologically, culturally, and economically on condition that the forest is properly exploited. For that purpose, forest should be managed, protected, and exploited continuously for the sake of the people's welfare, not only for the present but also for the next generation. Jompi Preserved Forest Area is one of the preserved forest areas in Muna Regency, which is now in very bad condition. The people living around the forest are powerless. This research aims: to formulate a model of community empowerment adjusted to the local condition. The technique of collecting samples used is cluster sampling, covering 226 heads of family. The analysis used is correlation analysis of Rank Spearman (r5), Multiple Regression, and Path Analysis. The result of analysis shows that the people's productivity and capability are still relatively low. This condition is resulted from the physical, human, and social capitals in the community. Similarly, the low capability of the empowerment facilitators and empowerment process also contribute to this situation. The effective empowerment model for the community around the preserved forest is the one that integrates the physical, human, and social capitals, and the facilitators' capability and empowerment process to create the power that can improve the productivity and capability of the community living around the Jompi Preserved Forest Area.
