Abstract

The Sigli - Banda Aceh Toll Road is the first toll road in Aceh province, stretching 74.2 kilometers (km) and consisting of 6 sections. Rock excavation work includes excavation of rock chunks with a volume of 1m3 or more and all rocks or other materials whose excavation requires air pressure tools or drilling, and blasting according to the instructions of the Work Director. This study aims to determine the stages or methods of rock excavation work using the blasting method and to analyze costs based on the Powder Factor (PF) value and the time required to complete the rock excavation work. Based on the results of the study, the stages of rock excavation work using the blasting method begin with the construction of an explosives warehouse, preparation for drilling blast holes, drilling, mobilization of explosives, filling blast holes with explosives (charging), blocking blast holes (stemming), connecting the blasting series (tie up), preparation before blasting, blasting and post-blasting checks. Blasting geometry applied to the rock excavation work in the Sigli – Banda Aceh Toll Road Project Section 1A Sta 15+350 – Sta 15+750 includes the following for the Initial Geometry Plan: Hole Diameter (D) 3.5 inches, Burden (B) 2.5 m, Spacing (S) 3 m, Height of the Stage (H) 6 m, Explosives 30 Kg, and PF 0.67. Geometry Realization: Hole Diameter (D) 3.5 inches, Burden (B) 2.5 m, Spacing (S) 3 m, Height of the Stage (H) 6 m, Explosives 30 Kg, and PF 0.67. Expand Geometry: Hole Diameter (D) 3.5 inches, Burden (B) 3 m, Spacing (S) 3.5 m, Height of the Stage (H) 6 m, Explosives 30 Kg, and PF 0.48. The Powder Factor (PF) value in the blasting geometry design obtained a PF value exceeding 0.3 kg/m3 which means it is not economical, the economical PF value ranges from 0.20 - 0.30 kg/m3. Economical Geometry Design is obtained by "trial and error" or rule of thumb according to the limits of ICI Explosives with the results: Hole Diameter (D) 3.5 inches, Burden (B) 3.5 m, Spacing (S) 5 m, Height of Tier (H) 6 m, Explosives 30 Kg, and PF 0.29. The time required to complete the rock excavation work on the Sigli - Banda Aceh Toll Road Project Section 1a Sta 15 + 350 - Sta 15 + 750 with the initial planned geometry design takes 3.77 months at a cost of Rp. 40,336,928,850.00 while with an efficient geometric design it takes 1.62 months with a cost of Rp. 39,678,466,850.00.

Abstract

This study aims to analyze parking characteristics and their impact on traffic performance on street HOS Cokroaminoto, Kisaran, Asahan Regency. This location is an area with quite high trade and culinary activities, so that the roadway is often used as a parking area. The problem that arises is the reduction in the effective width of the road which impacts the smooth flow of traffic. The research method used is a field survey approach by conducting direct observation of parking activities at three research locations. Data collected include the volume of vehicles entering and exiting, parking duration, parking accumulation, and parking turnover rate. The analysis was conducted using the guidelines of the Directorate General of Land Transportation (1996) and the Regulation of the Minister of Transportation Number 34 of 2014 concerning parking management. The results of the study indicate that parking activities on Jalan HOS Cokroaminoto have not been optimally organized. The parking patterns used are mostly perpendicular (90°) for motorcycles and parallel for cars. The parking turnover rate is relatively low, indicating inefficient vehicle turnover and causing limited parking space. Based on the analysis, it can be concluded that parking activity on street HOS Cokroaminoto has reduced road capacity and reduced traffic flow

Abstract

This study aims to evaluate the geometric conditions and level of service (Level of Service/LOS) of sidewalks on Jalan Madong Lubis, Kisaran Timur District, Asahan Regency. Sidewalks are important facilities for pedestrians that function to provide safety, comfort, and smooth mobility. However, in the research area, sidewalks face various obstacles such as street vendors (PKL), illegal parking, and utilities that reduce their main function. The research method uses a descriptive quantitative approach with primary data collection through direct observation of sidewalk conditions and counting the number of pedestrians on several road segments for six days. Secondary data includes regulations and technical standards from the Minister of Public Works Regulation No. 03/PRT/M/2014 and the Indonesian Road Capacity Manual (MKJI) 1997. The analysis results show that the width of the sidewalk on Jalan Madong Lubis is only 1.3 meters, below the minimum standard of 1.5 meters. The level of service of sidewalks on segments A, B, and C is in category B to C, while segment D experienced a drastic decrease to LOS F because almost all of the sidewalk space is covered by street vendors. Physical obstacles and damaged surfaces contribute to reduced user comfort and safety. Recommendations are provided to improve the physical condition of sidewalks, regulate street vendor activity, and provide supporting facilities to enhance sidewalk service levels as safe and comfortable pedestrian spaces
