Abstract

Opening modification of castellated beam now has varied including circular, diamond and hexagonal, in the selection of openings required data behavior as the basis of planning according to the desired conditions. The purpose of this study is to know the behavior of short-span castellated beam with variations of circular, diamond and hexagonal openings using finite element method. The geometry of the 1 meter span castellated beam used 225x75x7x5 mm. The method used to create a numerical model castellated beam with circular openings that are analyzed using finite element method then verified with experimental model results with geometry, material and loading the same. After the numerical model result closer to the experimental model, then created 5 variations of the geometry of numerical model openings for each variations. The results showed that the variation in the height and width of the same openings in the three types of openings obtained for the circular opening beams have greater deflection than the others because of the larger holes ratio. For diamond opening beams, the ultimate load is greater than the other because the ratio of the smaller holes ratio and for the hexagonal opening beams has the smallest deflection and stress than the others.

Abstract

Muara Enim road segment SP. Sugihwaras very potential to occur landslide based on its location which is on the edge of the river. Recorded by the National Road Implementation Institute (BBPJN) III has been a slope grid in 2014. Slope improvement efforts undertaken by the Ministry of Public Works using a combination of gabion not too successfully overcome the problem. In addition to the strength element of a construction work, the cost and timing of the implementation are also important considerations in planning. Slope at 173 + 535 - Km 173 + 705 along 170 m using soil nailing planned three nails with 19 mmnail diameter and angular slope of 20° with variation of nail length, nail installation spacing, safety factor (SF) and estimated working time to the cost. Using the SPSS.16.0 program, the variations are modeled by nine samples as multiple linear regression equations. Based on the SPSS output, then tested the classical assumption and feasibility test model which produced the model: Cost (million) = - 3159,475 - 54,097 length - 1354,256 distance + 5188,127 SF + 26,483 time. The Budget Plan (RAB) covers preparatory work, drainage system, soil nailing, and shotcrete. An efficient cost estimate of 8 m length nail, 1.5m installation distance, 1.5 safety factor and 64-day working time resulted in a cost of Rp. 3.853.485.500,00 (Three billion eight hundred fifty three million four hundred eighty five thousand rupiah).

Abstract

Occupational Safety and Health (K3) issues in Indonesia are still often neglected. This is because all parties involved in the construction project from the highest level of project leader to the lowest level such as rough labor, still pay less attention on the Occupational Safety and Health (K3) in every stage of construction work. In this research will be investigated the occupational accident risk, occupational accident risk assessment, and occupational accident risk management, so it can be proposed mechanism of occupational accident risk control at construction project of Musi Bridge VI Palembang. Occupational accident risk identified through interviews and observation. Risk assessment is determined by questionnaire. Risk assessment refers to a method of AS / NZS 4360: 2004 to determine the level of risk. Risk control using Job Safety Analysis (JSA). Data processing shows that there are 64 occupational injury risks, i.e., 13 low risk, 47 medium risk, and 4 high risk. It can be concluded that the highest risk factor for the workers is inhaled the welding smoke with the risk index of 16. Workers are required to use PPE in accordance with the type of work, strict supervision of workers in the usage of PPE, checking the work environment (safety patrol) on a regular basis, safety talk every week, installation of safety signs and worker’s health inspection.

Abstract

The influence of land cover and intensity is one of the factors that influence the value of surface flow coefficient (C). The coefficient value will affect the surface flow occurs during peak discharge. In this research, calculate surface coefficient (C) with variation intensity 40 mm/h, 50 mm/h, 60 mm/h, 70 mm/h for land cover paving block (brick pattern and matting pattern), grass block , mini elephant grass, sand and concrete pavement. This test is expected to be the solution in choosing the right type of land cover as a substitute for concrete pavement in the parking lot, park, or home or office yard. The implementation methodology was carried out by laboratory testing with rainfall simulator, 4 cm high base layer of sand and various land cover around 4 cm. The test that carried out in this study include filter analysis, rain intensity and surface coefficient value (C) testing. Testing value of coefficient including the test using rational formulas and testing by definition (Scwab, 1981 and Mc Guen, 1989). The result of this research obtained coefficient of land cover paving block pattern of stacking brick 0,857-0,891, in land cover paving block matting pattern 0,825-0,856, while at grass block 0,677-0,765. The coefficient of surface flow (C) for concrete pavement cover is 0.961-0,997, mini elephant grass cover is 0,483-0,538, while without land cover is 0,559-0,639. The value of surface flow coefficient (C) is getting bigger with increased rain intensity and land cover that has fewer gaps, in this case there is a significant difference in the paving block and grass block.

Abstract

Pengaruh temperatur peneraman pada kekuatan beton, mortar atau tanah berbutir kasar yang distabilisasi dengan semen sudah banyak dilaporkan didalam literatur. Namun demikian, pengaruh tempertaur pemeraman pada tanah lempung yang distabilisasi dengan semen masih belum banyak dilakukan. Perbedaan mendasar antara kedua hal tersebut adalah adanya reaksi posolanik yang terjadi didalam tanah yang distabilisasi dengan semen yang menghasilkan perilaku geser yang lebih kompleks dibandingkan dengan pada beton, mortar maupun tanah berbutir yang distabilisasi dengan semen. Serangkaian pengujian dilakukan pada penelitian ini untuk mengkaji perbedaan tersebut dengan menggunakan lempung lokal yang diambil dari Wates yang distabilisasi dengan semen portland biasa (ordinary portland cement). Sejumlah komposisi campuran lempung Wates- semen diperam dengan temperatur pemeraman yang berbeda (25, 30, 40, dan 50OC). Kuat geser tanah tersebut diuji di dalam alat kuat tekan bebas dengan waktu pemeraman yang berbeda – sampai dengan 56 (limapuluh enam) hari (7, 14,21, 28, 36, dan 56 hari). Hasil penelitian menunjukkan bahwa : Kuat tekan bebas tanah lempung anorganik yang distabilisasi dengan semen meningkat dengan bertambahnya suhu pemeraman pada waktu pemeraman yang sama akibat tingginya derajat sementasi dan reaksi posolanik.Pada kandungan semen rendah, reaksi posolanik tetap berlangsung oleh adanya disosiasi silikat dan aluminat pada temperatur tinggi. Kadar air pada saat pencampuran berpengaruh pada hasil kuat tekan bebas walaupun waktu dan suhu pemeraman sama.Jika dibandingkan dengan hasil-hasil penelitian terdahulu yang diacu dari referensi, hasil penlitian menunjukkan kecenderungan yang mirip.

Abstract

Mohammad Hoesin general hospital (RSMH) is a public hospital owned by the Government of Palembang located at Jl. Sudirman . It is located in a densely populated area with total built area of ± 20 ha. The absence of adequate infiltration area plus improper drainage condition and capacity caused floods as high as ± 30 cm in the parking lot which is at the lowest elevation. In order to overcome these problems, RSMH took the initiative to build a retention pond. This study aims to analyze the feasibility of retention pond development plan along with its drainage network through the duflow modeling studio (DMS) approach and spatial analysis of Geographic Information System (GIS). Total catchment for the study area covers the area of ± 46 Ha with the maximum runoff discharge obtained from the modeling results Q = 0,2 m3/s while the waste water effluent that is discharged into the drainage channel Q = 0,0021 m3/s is not too significant therefore can be ignored. Capacity of retention pond with minimum area of 0,7 Ha is sufficient to serve the catchment area, but it should be considered the use of pumps with a capacity of at least 150 lt/s to overcome high elevation difference.
