Abstract

Abstract. The north coast road is the main route that connects several provinces, cities, and regencies on the north coast of Java. The road is traversed by many heavy vehicles loaded with goods, so there is the potential for frequent violations caused by excessive loads. Given these problems, this study aims to determine the effect of excessive load on heavy vehicles on decreasing road life.The data used are primary and secondary data, primary data in the form of photos of observations at the Subah Weighbridge and interviews with the head of the Subah Weighbridge, secondary data in the form of actual vehicle weight data from the Subah Weighbridge, LHR, and road age from the National Road Planning Center. Central Java – DI Yogyakarta, then calculate the percentage value of VDF due to overload and decrease in the design life of the road using the vehicle damage factor value using the Bina Marga method (1987).The results of this study indicate that excessive load on heavy vehicles can affect the decrease in road design life. With the actual overload that occurred on Jalan Pantura KM 11 to KM 21, Batang Regency, the cumulative VDF increase based on the Bina Marga method (1987) was 2.63%. The decrease in design life due to actual overload based on the Bina Marga method (1987) was 0.04 years.

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

Revetment is a strengthening structure on river slopes from erosion. Erosion of river slopes can widen the wet cross section of the river and increasing scouring can endanger the surrounding buildings. The construction of the Demangan Water Gate in Surakarta City (Phase I) is planned at the mouth of the Pepe river downstream. The construction work will result in changes in river morphology, therefore it is necessary to protect the river slopes so that landslides do not occur. Apart from being a river slope protector, the Revetment design can also be a recreation area and an inspection road. The construction to be used is a concrete sheet pile revetment with reinforcement of the piles behind it as an anchor. Between the concrete sheet pile and the concrete pile, it is connected by a beam-slab structure so that it becomes a portal system. River slope stability analysis using GeoStudio2018 R2 software. River slope conditions that may occur are applied in several modeling, including: River slope conditions without Revetment reinforcement, River slope conditions with Revetment reinforcement, Conditions when changes in river water level elevation occur and river slope conditions when erosion occurs. Based on the results of modeling analysis on the original slope when the river water level increase then recedes has the smallest safe number (SF = 1,822). This is because on the back side of the Revetment, the active soil pressure is in a saturated condition, while the front side of the Revetment loses hydrostatic pressure as a counterweight. The highest safety number is in slope modeling with Revetment strengthening when the river water level increase (SF = 3.114), because the hydrostatic pressure on the back and front of the Revetment is balanced. Revetment construction on river slopes increases the safety rate by 30.64% - 43.70%. With the strengthening of the river slopes, it is hoped that it can provide sufficient security from the main function of protecting the river slopes and obtaining additional functions as a recreation area.

Abstract. Road is one of the transportation infrastructure that plays an important role in supporting regional development, increasing the regional economy, facilitating the mobility of people, goods and services. For this reason, in order to support national economic activities, the Ministry of Public Works and Public Housing through the Directorate General of Highways carries out the planning and construction of several new roads on an ongoing basis. In addition, for existing roads, the Directorate General of Highways needs to carry out maintenance so that existing assets can continue to function. The threat of natural disasters and the instability of road bodies is a serious problem. This can cause damage to the road body and even the road body can be cut off suddenly, resulting in reduced road performance. One of the roads in Maybrat district, precisely in the Ayawasi – Sisu KM 273+500 section, experienced a road collapse that cut off access between districts, resulting in a stagnation of economic activity. Therefore, a landslide handling design is needed so that the road can be accessed again.The design process was carried out through several stages, including Preliminary Survey, Hydrological Survey, Geotechnical and Geological Survey, Topographic Survey, and Planning. In the planning process, the most effective and efficient design will be selected according to field conditions. Slope stability analysis using Slope/W software. Based on the results of the planning, the design of the Concrete Soil Retaining Wall with bored pile reinforcement is used as an alternative treatment because it can be done easily in the field and can overcome the problem of landslides in the area.Keywords: Safety factor; Concrete Retaining Wall; Bored Pile; Landslide; Slope-W
