Abstract

A large number of bends in Cianjur Regency makes the Cianjur Regency area prone to traffic accidents, especially for heavily loaded vehicles, one of the corners that often occurs in cases of accidents on heavily loaded vehicles is the Tapal Kuda Cianjur bend. The problem with bend Tapal Kuda Cianjur is that the bend has a small radius so it makes the curve very sharp in uphill road conditions so it is very difficult for heavily loaded vehicles to pass corners and resulting in accidents on heavily loaded vehicles. The method used is a geometric analysis method to provide an overview of field conditions and stop visibility distance analysis which aims to determine the stopping visibility on the corner so that it is expected to meet the standards set by Bina Marga so that the view of the road users when passing a corner is not blocked. The results of the geometric analysis show that the bend is still feasible to accommodate traffic loads, the bend has a spiral-spiral shape with a value of Rc=30 m, Ts= 40,599 m, Es=9,152 m with a stop visibility value at the existing condition =17,300 m and does not comply with the provisions in the minimum stop visibility distance table. So it is necessary to improve the shape of the bend using a planned speed of 60 km / h, improvement of the shape of the bend is planned using the form of SCS and FC with values of Rc= 120 m and Rc=500 m and total arc SCS=196,878 m, FC=611,982 m with the value of the repair bend stop visibility distance repair bend both spiral-circle-spiral and full circle shapes of 82,117 m and in accordance with the provisions set by Bina Marga.

Abstract

Penggunaan beton di Indonesia semakin berkembang, dengan teknologi yang semakin maju maka penggunaan beton dituntut untuk semakin meningkatkan kekuatan beton. Pemadatan dengan menggunakan vibrator pada tulangan yang rapat tidak menjamin menghasilkan beton yang baik. Self Compacting Concrete (SCC) merupakan salah satu alternatif untuk mengatasi masalah tersebut, yaitu mampu memadat sendiri tanpa menggunakan alat pemadat ataupun vibrator. Penggunaan semen membawa dampak negatif terhadap pemanasan global. Oleh karena itu pada penelitian ini, untuk mengurangi penggunaan semen digunakan bahan tambah berupa fly ash sebagai bahan pengganti semen. Variasi penggunaan flay ash sebagai pengganti semen yaitu 5%, 10%, 15% dan 20%. Penggunaan bahan tambah zat aditif juga digunakan pada pembuatan Self Compacting Concrete (SCC), zat aditif yang digunakan dalam penelitian ini berupa Superplasticizer tipe E. Penggunaan Superplasticizer yang digunakan pada penelitian ini yaitu sebesar 1%.  Penelitian ini bertujuan untuk mengetahui kuat tekan Self Compacting Concrete (SCC). Adapun pengujian kuat tekan beton Self Compacting Concrete (SCC) dilakukan pada umur 28 hari. Berdasarkan hasil pengujian diketahui bahwa workability dan kuat tekan beton Self Compacting Concrete (SCC) menurun seiring dengan bertambahnya kadar fly ash. Kuat tekan tertinggi yaitu pada campuran fly ash dengan variasi 5%, yaitu dengan kuat tekan sebesar 21,543 MPa, yang mana telah memenuhi kuat tekan rencana sebesar 20 MPa. Kata Kunci: Self Compacting Concrete (SCC), fly ash, workability, kuat tekan.

Abstract

Asphalt is one of the materials used as road pavement material. One way to prevent damage to road pavement due to vehicle load is to improve the quality and stability of the pavement, but considering that road pavement materials such as asphalt cannot be renewed, other alternative materials are needed as asphalt replacement materials. The material used as a substitute for asphalt is a mixture of plastic waste and resin resin. This utilization is intended to reduce the existence of more and more plastic waste and utilize materials from natural plants. This study aims to determine the characteristics of a mixture of plastic waste and resin resin as a substitute for asphalt on flexible pavement. The test results obtained with the addition of more plastic waste, the penetration test value decreases, the test value of the softening point increases, the specific gravity test value decreases.

Abstract

Construction projects are complex jobs within a certain period of time involving many resources such as materials, machines, methods, money, and manpower. Manpower is one of the resources with limited supply, high cost, and often causes problems due to fluctuations. Manpower needs to be analyzed for costs and distribution using the resource leveling method with the help of software in order to obtain the most efficient results. Manpower analysis was conducted under planning conditions, real implementation in the field, and after leveling. Labor allocation at planning (120 days) produced a graph with sharp fluctuations. There is a manpower allocation that exceeds the maximum capacity of daily manpower, making it inefficient. The highest manpower allocation was 167 workers/day, 9 masons/day, 43 carpenters/day, and 35 ironworkers/day at a total cost of Rp1,015,560,000. Meanwhile, the conditions in the field (120 days) equated to a daily manpower requirement of 55 workers/day, 4 masons/day, 16 carpenters/day, and 14 ironworkers/day at a total cost of Rp1,149,600,000. Meanwhile, the allocation of manpower must also take into account the type and volume of work to be completed. Furthermore, based on the results of the resource leveling study (144 days), a labor allocation with a low fluctuation graph was obtained. The allocation of labor is well distributed and no one exceeds the maximum capacity of daily manpower so that it is more efficient. It takes a total labor cost of Rp1,015,920,000. The comparative results of the three conditions have significant disparities. Labor after leveling results in the most efficient allocation. Meanwhile, labor before leveling results in the most efficient cost. Key words: Resource Allocation, Resource Leveling, Manpower Cost.

Abstract

Abstract: The Green House display building is an exhibition building of living plants from various mountains in Indonesia including the mountains of Java, the mountains of Sumatra, the mountains of Kalimantan, and the mountains of Papua. This building is the only building in Indonesia, which presents the atmosphere of the mountains exactly the same as the original mountains, both plants, soil and air temperature, but is in a closed room. This building is very prone to fire because there are so many flammable materials such as leaves, wood and others. Therefore, the application of Building Fire Safety Management in this building must be applied as well as possible. To analyze the above, an inspection of the building's fire safety system equipment will be carried out for compliance with applicable regulations. The analysis will be carried out by checking directly and participating in tests or tests on the function of the installed fire protection system. The inspection and testing of the fire safety system in question includes: checking the completeness of the fire protection system, checking the use of fireproof materials, checking the provision of evacuation route access and checking the reliability of fire safety. Based on the results of the inspection and tests, it can be concluded that based on NFPA standards and the Regulation of the Minister of Manpower and Transmigration of the Republic of Indonesia No: 4/MEN/1980, yard hydrant equipment and Light Fire Extinguishers in the Green House Display building, still do not meet the requirements, but for the use of building materials in this building, almost all of them can be categorized as building materials that are quite resistant to fire/not flammable. For access to fire safety facilities/evacuation routes in this building is well installed and the radius of coverage is in accordance with the Indonesian Minister of Health Regulation number 48 of 2016, which is a maximum of 45 meters between emergency stairs. As for the reliability of the building safety system in this building, it can be categorized as "Good" based on the Puslitbang PU Pd-T-11-2005-C.

Abstract

Coastal embankments are structures built along the coastline with the aim of protecting coastal areas from longshore transport. Soil compaction testing aims to determine the maximum density of a type of soil by means of impact. Increasing soil density can be done by various methods, one of which is the Sand Cone method. Sand Cone method is very important in determining the type of soil used in construction and as a guide in calculating the strength and stress required in the coastal embankment structure. The research method in this paper is quantitative. The direct shear strength test obtained normal stress results with samples 1, 2 and 3 sequentially of 24.4 kPa, 48.8 kPa, and 73.2 kPa. Shear stress results with samples 1, 2 and 3 were 24.5 kPa, 41.2 kPa, and 55.9 kPa respectively. With soil samples 1, 2 and 3 loaded with 8kg, 16kg, and 24kg respectively. It can be concluded that the soil is categorised as sandy gravel type soil and is solid. Atterberg Limit testing obtained a liquid limit value of 52.90%, Plastic Limit 32.69%. and Plasticity Index of 20.21% can be concluded to be a type of clay. Soil compaction test results obtained moisture content of 36.21%, wet volume weight of 1.63 gr / cm3, specific gravity of 2.553, optimum moisture content of 35.80%, and maximum dry weight content of 1.26 gr / cm3.
