Abstract

This study analyzes the application of time management using the crashing method on the Rehabilitation Project of the Disdikbudpora’s Hall Building in Semarang Regency. This project has an implementation period of 57 calendar days. To assess whether this duration could be optimized, the crashing method was applied to critical path activities by adding overtime work hours (1 to 3 hours/day). The research utilized a qualitative method with a quantitative approach, using primary data from field observations and secondary data such as schedules and weekly reports. Results showed that by adding 1, 2, and 3 hours of overtime, the project duration could be reduced to 54, 49, and 48 days, respectively. Cost analysis revealed that adding 2 hours of overtime provided the most optimal balance between shortened duration and additional labor costs, totaling IDR 58,556,562.50. This option offered a 5 day acceleration with a relatively small cost difference compared to 1 hour overtime. Therefore, adding 2 hours of overtime is considered the most efficient strategy for project acceleration.

Abstract

Abstract. The Semarang toll road is the only toll road network in the city of Semarang at this time. The construction of toll roads aims to reduce congestion and improve travel time efficiency. In addition, the benefit of toll roads is that toll road users will benefit in the form of vehicle operational cost savings (BOK) and time compared to if they pass through non-toll roads. For alternative routes or non-toll roads, conventional roads can be chosen by motorists without passing through toll roads. This study aims to calculate vehicle operating costs (BOK), vehicle operating cost benefits (BKBOK) using the Pacific Consultant International (PCI) method as a limit to determine toll rates and analyze the comparison of Vehicle Operating Costs (BOK) on toll and non-toll roads. . Data collection techniques in this study used primary and secondary data collection techniques. The analysis was carried out using an interactive analysis model. The calculation of vehicle operating costs using the PCI method is taken from the lowest vehicle operating costs from various speed variations. For toll roads, the lowest vehicle operating costs occur at a speed of 60 km/hour with a total BOK of Rp. 6,803.54. Meanwhile, for non-toll roads, the lowest vehicle operating costs occur at a speed of 60 km/hour with a total BOK of Rp. 10,641.27. According to the analysis we have obtained, toll roads are cheaper than non-toll roads. For road users in the city of Semarang, it is recommended to use the Semarang section A toll road compared to non-toll roads, because vehicle operating costs are more efficient and have a much faster travel time.Keyword : BOK,BKBOK, speed, PCI, Toll Road

Abstract

In formulating the seismic design criteria for a building at ground level or determining the amplification of the peak earthquake acceleration from the bedrock to the ground for a site, the site must be classified first. Site class assignment must be carried out through field and laboratory soil investigations. Site Class consists of SA (hard rock), SB (rock), SC (medium soil), SE (soft soil) and SF (special soil). SNI 1726: 2019 with various classes of SB, SC, SD and SE sites. From the analysis results, it is found that the variation of soil site classes has an effect on the area of minimum reinforcement requirements, except for the logitudinal reinforcement requirements of the lower support beam for site class variations, the value is fixed. The variation of soil site classes has a significant effect on the area requirements of the longitudinal reinforcement in the column. The largest requirement for column longitudinal reinforcement is Soft Soil Site Class (E) and the smallest requirement is Rock Site Class (B).
