Abstract

Reinforced concrete unit price is influenced by the weight of steel reinforcement and concrete molds. Consumption coefficient factor 1 m3 concrete steel reinforcement seen from the use of reinforcement factor corresponding coefficient analysis list Bakhtiar Ibrahim, 1996 and Burgerlijke Open bare Werken (BOW), J. A. Muko - Muko, 1995, which is tied as the denominator vareabel weighing 110 kg/m3. Calculation results 1 m3 of concrete iron needs by operation as the numerator, that will get the value of the index coefficient analysis for concrete work. From the results koefiseien index value multiplied by all the coefficients contained in the analytical use of reinforcement or BOW Bakhtiar. This result will be a factor coefficients are used as the basis for calculation of unit price analysis used iron as needed according to the picture implementationKeywords : variable, use of reinforcement, formwork, the value of the coefficient

Abstract

Sutami Dam is a dam with the largest reservoir with managed by Perum Jasa Tirta I. This reservoir has been operating for more than 39 years (operates in 1972 and using reference to recent data in 2011). This study was performed to determine the trend of sediment discharge and reservoir live time in order to find out how the rest of the remaining Sutami reservoir for reservoir operations. Data analysis is used as the data for 6 years period and in 1972 data for comparison. Point source of sediment in the reservoir is divided into two points, Sutami sediments by direct inflow to the the Sutami Reservoir (Metro River) and outflow from Sengguruh Reservoirs (Brantas River and Lesti River). The third point is the calculation of sediment discharge to determine the most influential point sediment carrier in Sutami Reservoir. Reservoir live time to the rest of Sutami calculated using three methods of approach. Volume approach, elevation approach, and empirical approaches. 2 Tanpa nomer halaman The point that has the most impact is of the Brantas River (inflow from Sengguruh Reservoir) with Qs = 2.27 kg/sec (2011), then from the Metro River with Qs = 1.97 kg/sec (2011). ). Based on the analysis of the remaining life time for Sutami Reservoir using three methods of approach, it is known to Sutami Reservoir live time trends tend to decrease. Elevation control point (+233.3 m) with elevation approach and volume approach gives results for the remaining life of 5 years and 1.5 years, while the empirical approach with 97% trap efficiency give results 9 years for the remaining life time of Sutami Reservoir.Key words: Sutami Reservoir, Sedimentation, Reservoir Live Time

Abstract

Kubu Subdistrict is located at Karangasem District and belongs to Tejakula Groundwater Basin. It is droughty region with few rainfalls compared to other region. The purpose of this research is to determine the quantity and the quality of groundwater for agriculture. The analysis of groundwater quantity is by applying the pumping test. The pumping test is divided into two stages, which are well test and aquifer test. Result of well test at 7 (seven) production wells is obtaining the optimum discharge ranging from 10.107 liter/second to 18.604 liter/second. Aquifer test analysis involves the first stage is to determine the type of flow from each well that is steady or unsteady flows, and then determine the method that will be used based on the type of flow and type of aquifer. In determining the type of flow is obtained steady flow types for 3 (three) wells and unsteady flow types for 4 (four) wells. Groundwater quality analysis is conducted by Aquachem software version 2011.1 (demo version). Based on the analysis of groundwater quality, groundwater is containing low and medium Sodium and have high and very high salinity.Keywords: quantity, quality, groundwater, wells test, aquifer test, Sodium.

Abstract

The change of global climate influences the temperature, relative humidity, sunlight time, wind rate, rain rate, and river debit. The higher intensity of rain rate after the change of climate influences the fluctuation of river debit in rainy or dry season. Flood and dryness are natural occasions, which are usually occurring. Sutami Reservoir is functioned to retain water excess from rain and river debit from Brantas River, which in the future it would be stored. River debit is used to fulfill water need in dry season. Therefore, to face the extreme effect, there is needed management planning of reservoir operation managed well and optimally. Methodology used in climate change analysis toward operation model of Sutami Reservoir is Stochastic Dynamic Program and it is obtained a policy system of operation model output before and after climate change. Based on the result of analysis, it shows that there is climate change in Sutami Reservoir where it is signed that optimally reservoir output is changed. In the table of optimally reservoir output shows that before climate change the output policy is still in good condition while after it, the output policy is change where there is any displacement of wet season and dry season in which it causes the debit to Sutami Reservoir changed from what had been expected.Key words: climate change, reservoir operation model, stochastic dynamic program
