Ari Syaiful Rahman Arifin — 2024-03-18

Earthquakes are natural disasters that often hit Indonesia, causing various losses in human life, including damage to homes and places to live. Therefore, the importance of building earthquake-resistant houses cannot be ignored. The research aims to obtain a comparison of the estimated cost of a type 36 simple house construction project, by considering the comparison between conventional structures and structures that are strengthened to resist earthquakes. The data used involves working drawings, technical specifications, and work unit price analysis (AHSP) based on PUPR Ministerial Regulation No. 8 of 2023 and a list of unit prices for wages and materials for work in the Public Works and HSBGN sector for the 2022 fiscal year in the city of Padang. The cost estimation results show that for a simple house with a conventional structure, the construction cost is IDR 243,000,000, while for a simple house with earthquake-resistant reinforcement, the cost reaches IDR 251,800,000. This additional cost was caused by strengthening work on foundations, columns and beams, walls, and trusses. Even though there was an increase in costs of around 3.63%, this result can be a consideration for the community. It is important to realize that with relatively small additional costs, people can increase safety and comfort in building construction. The results of this research can be a strong basis for stakeholders in the construction and policy fields to consider safety and comfort as the main factors in developing housing infrastructure.

The Effect of Changes in Flood Discharge on Sedimentation Rates in Middle Segment of Batang Kuranji Check Dam using HEC-RAS 6.0.0

Septi Wila Zarinda — 2024-04-01

The magnitude of the longitudinal slope of river gratly determines the magnitude of sediment transport. This is due to the large flow velocity. This shape causes gradation of the river bed, especially upstream of the river. This phenomenon is seen in the middle segment of Batang Kuranji. where a sediment control buildg or check dam has been built. However, sediment transport and changes in river cross-section upstream still occur. Based on this phenomenon, a simulation of changes in flood discharge on sediment rate was carried out. This simulation was carried out using the Meyer Peter Muller method found in HEC-RAS 6.0.0. The simulation was carried out using 25 year planned flood discharge with smaller variations in discharge changes, namely Q1, Q2 and Q3. In general, the simulation results show that changes in flood discharge determine the magnitude of changes in sediment rates, the greater the flow discharge, the higher the sediment rate, both with and without check dams. The simulation results also show that the sediment rate in conditions with a check dam has decreased compared to conditions without a check dam, this shows that the presence of a check dam can reduce the sediment rate that occurred before the check dam was built.

The 5 highest barriers factors were identified, that is Lack of understanding of BIM and its benefits, Lack of government support, Requires high hardware specifications, High investment costs for BIM official licenses, Lack of market demand (Clients). With this research, it is hoped that the application of BIM can be better and provide maximum benefits to construction companies in Jambi City.

The Effect of Adding Coconut Coir Fiber on Compressive Strength, Tensile Strength, and Concrete Flexural Strength in Eco-Friendly Tetrapod Planning in Coastal Areas of IKN Supporting Cities

Hijriah Hijriah — 2024-03-31

Beaches often experience erosion or abrasion problems caused by various factors, such as climate change which triggers rising sea levels, high waves, human activities such as beach reclamation, and infrastructure construction that is not environmentally friendly, triggering erosion on the coast. In the coastal area of the city that supports IKN, which is located in the Balikpapan area, Manggar Beach, also experiences abrasion which causes land to narrow in that area. The abrasion that occurs erodes the coastal area around 7-8 meters every year. To produce environmentally friendly infrastructure, this research carried out the addition of coconut fiber waste components to tetrapod concrete used for breakwater construction. In this research, variations in the addition of coir used were 0%, 1%, 2%, 3%, 4% and 5%. The aim was to find out how much influence the addition of coconut coir waste to the concrete mixture had on the compressive strength, tensile strength and flexural strength of the concrete in tetrapods. and produce concrete that uses coconut fiber waste as an alternative material for tetrapod concrete as breakwater armor. Based on the analysis results, the quality of the concrete was 23 Mpa. This value was determined based on wave generation analysis. In addition, it is known that variations in coconut fiber affect the slump, compressive strength, flexural and split tensile test values of concrete. Based on the slump test results, it was found that the greater the variation of coconut fiber in the concrete, the lower the resulting slump test value. In testing the compressive, flexural and split tensile strength, it was found that the optimal composition for adding coconut fiber was 3%, in this composition the amount of coconut fiber fiber was able to improve the mechanical properties of tetrapod concrete compared to other compositions.

Comparative Study of Cost and Eco-Efficiency Factors of Aluminum and Conventional Formwork in The AYOMA Apartment Construction Project

Risma Apdeni — 2024-03-31

The AYOMA Apartment construction project used two types of formwork; both aluminum formwork and conventional formwork are applied on one floor. A comparison of the costs of the two types of formwork used has not been carried out in the project planning. This study aimed to obtain a comparison between aluminum formwork and conventional formwork in terms of cost and eco-efficiency factors. The comparison was made specifically on the formwork of the 3rd Floor of the West Tower, The AYOMA Apartment. The unit price analysis of formwork was based on the coefficient of each work item following the regulation on Unit Price Analysis of Public Works and unit price standards applicable in the project location area. The eco-efficiency factors were calculated from the waste produced by manpower. The calculation results showed that the cost of aluminum formwork for the 3rd Floor of West Tower of The AYOMA Apartment is IDR 2,708,328,757.73 or 2.25 times higher than the conventional formwork cost of IDR 1,204,987,034.60. However, when the reusability factor was considered, aluminum formwork is up to 14.83 times more efficient than conventional formwork. In the eco-efficiency factors analysis, the waste produced by manpower for the work of aluminum formwork is less, only 56.48% of the waste produced by manpower for the work of conventional formwork. The amount of waste produced from the main material and the quality of concrete produced by using aluminum formwork support the conclusion that aluminum formwork is more eco-efficient than conventional formwork.

Analysis of Passenger Car Equivalency (EMP) Values on Road Sections in BandarLampung City (Case Study: Ratu Dibalau Road Section and Damar Island Road Section)

Amelia Oktavia — 2024-03-31

The increase in vehicle volume in Lampung Province has resulted in a decrease in road performance. Capacity evaluation is prevention, determining capacity there are several parameters, one of which is EMP. In this case, the analysis of road section performance refers to MKJI 1997. The characteristics of MKJI 1997 are strongly influenced by the traffic of major cities in Indonesia which are made the place of empirical research in 1991 - 1995. Of course, there are differences in the characteristics that occurred in that year with the current situation. This study was conducted to determine whether there is a difference in the EMP value in MKJI with the current field EMP. This research uses field survey data including traffic volume, road section geometry, and Time Headway data between vehicles. In this study, the emp value is analyzed using the Time Headway method and the data for analyzing the performance of road sections refers to the 1997 Indonesian Road Capacity Manual (MKJI). The results of the emp MC value for the morning and afternoon peak hours on Section 1 are 0.48 and 0.46. Section 2 is 0.46 and 0.44. This value is significantly different from the 1997 MKJI emp of 0.25. for the DS value using emp MKJI on section 1, the results are 0.45 and 0.68. for DS emp calculations on section 0,3 of 0,43 and 1. For section 2 DS emp MKJI of 0.33 and 0.48. For DS emp calculations on section 2 of 0,48 and 0,65. It can be seen that significant differences can be caused by traffic flow conditions, differences in road characteristics, road gemetry conditions, and environmental conditions in 1997 with current conditions. It can also be seen that the greater the emp value will affect the amount of traffic volume so as to make the degree of saturation value greater.

Comparison of the Variation of Coarse Aggregate Gradation on the Strength of Concrete

Dwivan Dhama Laras — 2024-03-31

Concrete as the main construction material has an important role in determining the strength and reliability of a construction project. The quality of concrete is influenced by the properties of its constituent materials, such as gravel, sand, cement and water. Testing the compressive strength of concrete is an important step to assess its quality and ensure it meets construction standards. Although previous research has compared the compressive strength of concrete and changes in aggregate volume, this research still covers limited dimensional variations and further exploration of aggregate dimensional variations is needed. This laboratory study used a conventional concrete design according to SNI 03-2834-2000, with compressive strength tests carried out at the Material Testing Laboratory, part of the Civil Engineering Department at Politeknik Negeri Banyuwangi Banyuwangi. The experimental results recorded in the fourth chapter show that at 7, 14, and 28 days, type AG 10 has the highest compressive resistance value, statistically significant mean value, and also shows that type AG 40 has the lowest compressive strength value. Therefore, it can be concluded that the smaller the size variation of coarse aggregate, the higher the compressive strength of concrete. These findings provide a comprehensive picture of the compressive strength characteristics of concrete with varying coarse aggregate sizes.
