<![CDATA[Water is very important for human beings.Sources of fresh water that can be used are only 3% of the total water availability on earth, and 12% from that quantity are soureces of groundwater. Groundwater is one of the water resources that very important in sufficient human needs, such as domestic, agriculture or industry. Geoelectric is one of methods for groundwater investigation. The purposes of this research are to identify litholgy of soil layer, thickness of aquifer position on research location, determining hydraulic soil conductivity value and predict the groundwater reserve potential in Cisadane Watershed. This research was conducted in several steps, such as collected data and analysis data. The processed data was the secondary geoelectrical data with schlumberger method. Calculation of groundwater storage using geoelectric and Darcy’s law. Aquifer thickness layer obtained from the average content aquifer layer on research location, so it can represents the thickness of the aquifer. From the calculation result obtained groundwater reserve prediction amounted to 2.46 m3/second for unconfined aquifer and 8.64 m3/second for confined aquifer.]]>

<![CDATA[ABSTRACT Human disturbance such as land use changes, urbanization, and deforestation degrade Upper Cisadane Watershed. It also causes degradation of recharge area, decrease infiltration and increase runoff. The aims of this research were to (1) identify the criticality of recharge area; and (2) analyze the potential of water recharge in Upper Cisadane Watershed. The criticality of recharge area had been identified refers to regulation of the Minister of Forestry, Republic of Indonesia Number: P.32/MENHUT-II/2009 by scoring and overlaying of slope, soil type, rainfall, and land use map. The amount of water recharge potential was predicted by the equation issued by IWACO and WASECO (1990). The result showed that distribution of criticality of recharge area in Upper Cisadane Watershed in 2006, 2009, and 2013 were: (1) good: 24.7%, 24.7%, 23.6%; normal: 6.9%, 6.2%, 3.7%; (3) ranging critical: 17.9%, 17.8%, 19.4%, (4) rather critical: 25.0%, 24.9%, 30.7%; (5) critical: 23.9%, 24.5%, 22.0%; and (6) very critical: 1.9%, 2.0%, 0.7% respectively. The magnitude of the potential of water recharge on average in the recharge area was in good condition; 154.5 x 106 m3, normal; 33.9 x 106 m3, ranging critical; 94.6 x 106 m3, rather critical; 130.9 x 106 m3, critical; 98.2 x 106 m3, very critical; 6.2 x 106 m3. Upper Cisadane Watershed has a potential of annual water recharge was 511.7 x 106 to 569.2 x 106 m3/year or around 14% - 15.6% of total rainfall, with an average change in the potential of water recharge from the simulation based on the condition of recharge area in 2006-2009 decreased -0.04%, in 2009-2013 decreased -3.2% and in 2006-2013 decreased -3.3%.Keywords: recharge area, infiltration, runoff, criticality.]]>

<![CDATA[The aim of this research was to study the effectivity of bacterium in a simple anaerobic wastewater treatment reactor for degradating the pollutans. The configuration of the reactor used cylindrical plastic material with capacity of 150 L. Meanwhile, the supporting media that used as fixed bed reactor was bamboo with length 23-25 cm, width 3-4 cm, and thickness 0.5 cm. The surface area was 30 m2/m3, 40 m2/m3, and 50 m2/m3 that put into each bioreactor. The biofilm formed in bioreactor and fixed bed medium after cultivating during 30 days. By using the surface area of 50 m2/m3, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and ammonia dropped in aquaculture wastewater. The efeciency of BOD5 COD, and ammonia in sampling period test of seven days were 82.28%, 23.08%, and 46.95%, respectively.]]>

<![CDATA[Economic growth in Bangka Belitung Province is likely to increase. Such improvements have implications on the growing need for fossil fuels from various sectors that cause changes in air quality. Ministry of the Environment recommends doing an inventory of emissions. The load of emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), carbon monoxide (CO), and particulate matter (PM10) is the primary air pollutants dangerous to be inventoried. The average load of SO2 emission Bangka Belitung province of 6,045.89 tons/year and the largest contributor came from the industrial sector (41.43%). Load of NOx emissions by 16,324.84 tons/year, CO amounted to 75,639.01 tons/year, and PM10 amounted to 2,750.66 tons/year. The transportation sector is the largest contributor of load NOx emissions (62.11%), CO (96.58%), and PM10 (79.93%). The largest contributor of load of emissions SO2, NOx, CO, and PM10 in Bangka Belitung is Bangka. Bangka Belitung Provincial Government planned several strategies to reduce the load of emissions include smart driving, energy audit, centralized power plants, and the conversion of kerosene to LPG in the domestic sector. With the implementation of this strategy is expected to reduce load of emissions by 30%.]]>

<![CDATA[The increasing of high population rate, plus there was a new steel industry named PT. Krakatau Posco in Cilegon has made higher demand of clean and raw water. The Volume of Nadra Krenceng reservoir used by PT. Krakatau Tirta Industri is still doubted to fulfill water demand in Cilegon. The purpose of this research to analyze how much the reservoir volume capacity that will always be available and makes the program with Visual Basic Application in Microsoft Excel. The reliability calculation of Nadra Krenceng reservoir was conducted using three methods; F.J Mock, NRECA dependable discharge, and simulation the result of both methods use Weibull Method. The simulation result of Weibull Method shows for F.J Mock dependable discharge with probability of 95%, 90%, 80% and 50% are 5,023,095 m3; 5,733,905 m3; 7,215,525 m3; and 11,600,385 m3 respectively. For NRECA Method simulation, the result with the same series probabilities are 3,831,718 m3; 4,531,326 m3; 5,930,542 m3; and 10,128,191 m3 respectively. The Probabilities used by PT. KTI to guarantee the water availability in Nadra Krenceng reservoir is 80%. To conclude, the available volume of Nadra Krenceng reservoir now 7,215,525 m3 for F.J Mock Method and 5,930,542 m3 for NRECA Method. Both of calculation of water availability of Nadra Krenceng reservoir could achieve good enough accuracy. The R2 values for F.J Mock Methods is 0.685 and 0.653 for NRECA method.]]>
