Abstract

Indonesia is a country that is vulnerable to natural disasters, one of which is an earthquake. Because Indonesia is at the meeting point of the 3 most important major plates in the world, one of the effects of the earthquake is damage to building structures. Structural planning is needed for buildings with earthquake resistance from the many occurrences of earthquakes seen in recent times and the losses incurred.Pushover analysis is a non-linear static analysis. The static load captured at the center of mass of each floor is taken into account in this pushover analysis as the effect of the design earthquake on the building structure, the aim of which is to find out how the building structure will collapse during an earthquake so that you can know which parts of the structure are in critical condition and what to do if they do not meet the requirements.The results of the analysis show that the maximum base shear force for the x direction capacity curve is 484.6749 tons with a displacement of 0.095228 m occurring in the 6th step, while the y direction of the maximum base shear force is 555.339 tons and displacement of 0.152807 m occurs in the 14th step. The performance point value is also obtained from the analysis pushover in the x direction with = 475.025 tons and D = 0.087 m yield Sa = 0.205 g and Sd = 0.072 m, while for the y direction with = 499.168 tons and D = 0.086 m yield Sa= 0.225 g and Sd = 0.067 m. Then at the level of building performance in the x and y direction parametersMaximum Total Drift Ratio included in the category Immediate Occupancy (IO), it can be concluded that the building did not suffer significant damage, the building is safe when an earthquake occurs, the risk of loss of life and structural failure is not too significant and can be used again immediately.

Abstract

Asphalt concrete is a combination of aggregate, asphalt, with or without additives. To obtain high stability in asphalt concrete, it is necessary to have an aggregate that is well graded, dense, and has small voids between aggregate grains. Asphalt concrete performance testing can be done through the Marshall test. The Marshall Test Tool is used to determine the characteristics of a road pavement layer. One of the Marshall test kits that is still widely used in laboratories is the analog Marshall test kit. This study used an experimental method in the laboratory of the Jombang Regency Public Works Office with core test objects (KOR) made of a mixture of wear-resistant steel (AC-WC) with a thickness of 4 cm each. In this test, 4 core specimens were used in accordance with the 2010 General Highways Specifications (revision 3). With the composition of the constituent materials consisting of Aggregate 0-5 mm (42.2%), Aggregate 5 - 10 mm (33%), Aggregate 10 - 15 mm (16.9%), Filler Cement (1.9%), Asphalt Content (6%) those who get the value of 91.3% (stability) is the final residual stability value, before obtaining this value there are several values listed, namely; value 2,292gr/cm3 (Bj Mix), 5.274% (effective asphalt content), 0.772% (absorption of asphalt), 4.71% (VIM), VMA 16.80% (VIM), 71.97% (VFB ), 1178kg (initial marshall stability) , 3.55mm (flow), 332kg/mm (Marshall quetient).

Abstract

Jalan Raya Ploso, classified as a two-lane undivided road, serves as the primary route connecting Jombang Regency, Mojokerto Regency, and Lamongan Regency. This road is situated in a densely populated area that includes residential neighborhoods, commercial establishments, a terminal, and various vendors, resulting in a mix of vehicles such as large trucks, buses, motorcycles, and cars moving simultaneously. Traffic congestion frequently occurs due to several factors, including market activities, vehicle parking, and vehicles moving slowly or entering and exiting properties along the road. The aim of this research is to analyze the issues occurring on Ploso Highway and provide alternative solutions that can be implemented. The focus of the study is the unsignalized three-way intersection in front of Ploso Market. Observations indicated a road capacity of 2558 vehicles per hour (vph) with a degree of saturation (Dj) of 0.92. Since this degree of saturation does not meet the PKJI 2023 standard, which sets an ideal degree of saturation below 0.85, the researcher proposes an alternative solution involving widening the lane by 1.20 meters on the major road and 0.50 meters on the minor road.

Abstract

Profitability analysis is a key factor in evaluating the success of construction projects. This study focuses on the profitability of the Banjaragung - Pulosari road rehabilitation project in Jombang. The rehabilitation project spans 1,566 meters in length and 3 meters in width, with a project value of IDR 1,534,120,251. To determine the profit level, a profitability analysis is required. The main objective of this report is to provide an understanding of profitability analysis in the construction industry, particularly in the Banjaragung - Pulosari road rehabilitation project in Jombang, by presenting the Return on Investment (ROI), Internal Rate of Return (IRR), and Benefit-Cost Ratio (BCR) methods as tools for evaluating profitability. The analysis results show a favorable outcome with an ROI of 29% and an IRR of 10.42% per year, which is higher than the East Java Regional Development Bank’s Prime Lending Rate (SBDK) of 6% per year. A BCR of 1.0669 also indicates that the benefits exceed the costs, signifying that the project has high investment return potential and is viable to undertake.
