Abstract

The Tugu Dam is one of the National Strategic Projects located in Trenggalek, East Java. Dam construction is an old practice, so history of dam shows great innovations in engineering. The innovations are not only for foundation design, but for foundation failure repairing. In the conduit of the Tugu dam, there is displacement as far as 20 mm - 60 mm. The alternative foundation failure repairing is grouting. The purpose of this study is to identify problems in the foundation failure of Conduit Tugu Dam and to evaluate the effectiveness of grouting based on the lugeon value and displacement value in the simulation by software. The results of the investigation that obtained a colovial layer as deep as 15-28 (m) in the displacement. The Lugeon Value area by testing the water pressure is 3,54 – 104,13. After the grouting work is done and the water pressure test is carried out, the Lugeon value on the Check Hole is 1,01 – 4,95 so that the grouting effectiveness is 75% (good category). The results using sigma/w show that displacement without using grout is -0,394 (m) alternative 1 is -0,027 (m), alternative 2 is -0,051(m), alternative 3 is -0,034 (m) and alternative 4 is -0,026 (m).

Abstract

One of the issues that is still a problem in the upstream watershed, including thewater catchment area of Saguling Reservoir, is land use change. Changes in landuse in water catchment conservation areas into economic, industrial and residentialareas, will cause an increase in run-off during the rainy season and sedimenttransport to the reservoir inlet, while changes in land use downstream of thereservoir will cause an increase in demand. Therefore, research is needed todetermine the rate of increase in sediment yield that occurs in the watershed of theSaguling Reservoir. The integration of USLE and GIS allows us to determine thespatial distribution of parameters. Each factor in USLE is calculated using theexisting facilities in the GIS software. The results showed that there was anincreasing rate of sediment yield in the "Very Heavy" TBE category, while in the"Medium" TBE category the trend of sediment yields showed a downward trend.

Abstract

Erosion is a serious problem in watershed management. The Saba watershed is a water catchment area at the Titab Dam in Buleleng Regency, Bali Province. The existence of the Titab Dam is accompanied by the development of activities of the surrounding community, both tourism, economic and daily activities. Unfortunately, this activity in the future will have a negative impact on the condition of the dam so that it poses a risk. This study aims to determine the amount of sediment inflow with land erosion approach at the Titab Dam using the USLE (Universal Soil Loss Equation) method. Erosion rate prediction was carried out using the USLE method and with the help of ArcGIS 10.8 software. From the results of the analysis, it was found that in the Titab Dam catchment area, only 3 classes were obtained. The results of the calculation of the erosion rate using the USLE method showed that the magnitude of the erosion was 439,962 tons/year or 53.05 tons/ha/year. In addition, the most influential factors on the rate of erosion are the length and slope factors. In addition, land cover is also one of the most influential factors.

Abstract

Recently, the use of wallpaper and paint as a coating wall was in great demand. Wall coating was not only for the room’s aesthetics but was also used to keep the temperature of the room. The objective of this study is to determine the effect of wall coating type on the temperature's room comfort, specifically to know about the effect of using wallpaper and wall paint for the temperature of the room. The study also aims to compare the construction cost of using both materials. Temperature measurements in the room area consider to the occupant time activities, i.e. 6.00 am to 8.00 pm, it was measured on a grid with interval distance of 2m and elevation of 0,5m, 1m, 1,5, and 2m. The results of the comparison conclude that the wallpaper's wall is more stable for keep temperature of the room, but painted wall gives the effect of inside room more cooling. The Budget Plan (RAB) for setting up wallpaper was more expensive i.e. Rp. 180,965.00 per m2 than the cost of wall painting wall of Rp. 67,577.00 per m2. The Implementation Cost (RAP) was of using wallpaper also more expensive of Rp. 142,469.00 per m2 than wall painting is Rp. 58,383.00 per m2.

Abstract

Pore water pressure readings (piezometer readings) produce data that must be interpreted before being used for further analysis. This process is very influential on the results of the analysis because in the piezometer reading there is the possibility of anomalies due to potential delays or lags or errors in readings. The purpose and objective of this research is to provide an alternative approach to dam safety instrumentation inventory in order to be able to arrange maintenance work properly, effective and efficient, in conditions of limited budget can be used as a standard in making decisions in prioritizing piezometer maintenance. Several piezometer data processing methods can use techniques, including : interpretation of pore water pressure patterns; correlation simulation of pore pressure values and flow line plots. The results of the research on the piezometer at the Sermo Dam can be distinguished between conditions that have good pore water pressure readings and the opposite condition, with a ratio of 71,43% and 28,57%.

Abstract

This research aims to determine the characteristics of K-200 concrete according to Permen PUPR No. 28/PRT/M/2016 article B.06, using steel fibers (bendrat wire) with 2% steel fiber by weight of concrete volume and variations in the L/D ratio through laboratory tests. The total population is 12 specimens with a sample of compressive strength 5 specimens and split tensile strength 4 specimens for each treatment which is a random sample, i.e.: A (reference concrete); B, C, D, and E for concrete with 2% fiber and L/D ratio of 50; 62.5; 75 and 87.5. The test results of concrete materials meet the SNI. The significance level of 0.05 indicates that the test data are normal distribution and uniform. The hypothesis result shows that there is a difference between the reference concrete and the concrete fiber with variations L/D. The unit weight of concrete between the reference concrete and the concrete with variations of L/D is slightly different. The slump value decreases with the L/D ratio. Characteristics of the concrete increase up to L/D 75. Based on the design of K-200 concrete per-as Permen PUPR No. 28/PRT/M/2016 article B.06, compressive strength, split tensile strength, and flexural strength for reference concrete are 17,316 MPa, 2,317 MPa, and 3,083 MPa, greater than 35,9%, 43,8%, and 28,7% of design. Fiber concrete with variation of L/D, compared with reference concrete is greater than 32,7%, 39,7% and 26,2%.
