Betaubun Department of Civil Engineering, Faculty of Engineering, Musamus University Merauke, Indonesia ABSTRACT The intersection is a place of conflict between vehicles of two or more roads. Driver behavior and land use also influence intersections. This is the cause of the need for studies for intersection management. One study for intersections is the calculation of the intersection capacity itself. The capacity to be assessed, of course, requires data on the volume of vehicles passing at the intersection. The purpose of this study was to analyze the performance of the weekly intersections in Merauke Regency by using the Indonesia Road Capacity(Kapasitas Jalan Indonesia: KAJI) program.results of analysis of vehicle volume data passing for one week, the largest vehicle volume can be seen on Sunday at 17:00-18:00 WIT that is equal to 2038 vehicles / hour or 1153 pcu / hour. Calculation of intersection capacity using the KAJI application obtained a weekly intersection capacity of 2451 pcu / hour. The degree of saturation at a weekly intersection is Based on the results of the analysis it can be concluded that the service level of the four unmarked intersections is at level C, ie the current is stable but the speed and motion of the vehicle is controlled and the driver is limited in choosing speed.

Even intersection is a place of conflict and density, so almost all intersections, especially in urban areas, need regulation. For this reason, it is necessary to conduct studies related to the arrangement in this intersection area, in order 88 editor@iaeme.com

2 Herbin F. Betaubun to avoid and minimize the occurrence of conflicts and some problems that may arise in this intersection area. The purpose of the intersection setting is to reduce the accident of meeting several movements of vehicles from various directions to the same area, namely the space in the middle of the intersection. This condition will not actually be a problem if the flow from each part of the approach does not come together, but alternately. However, the reality is difficult to find, especially at intersections in urban areas, which in reality flows at the same time which will lead to conflicts between vehicles. Vehicle conflicts at the intersection occur because of the movement of vehicles, which can be broadly classified into: intersecting motion, merging motion, and separating motion, which is overall. Traffic and land use behavior affects the conditions in the city center (Betaubun, 2018; Betaubun and Betaubun, 2018; Betaubun and Hairulla, 2018; Hairulla and Betaubun, 2018; Pamuttu and Hairulla, 2018; Suyadi and Hairulla, 2018). The road network that is often traversed by vehicles, interspersed with intersections, will invite the emergence of economic activities, especially if the intersection is in a close position. Thus the intersection experiences a density of this because the area is a trading economic activity and residential area. Transportation problems such as: congestion, air pollution (Santoso and Mangkoedihardjo, 2013), accidents, queues and delays are usually found with low or large quantity levels. These problems are often found in several cities in Indonesia, including in Merauke Regency. In addition, the movement of vehicles passing through the intersection is not smooth, especially during peak hours due to the parking of vehicles that are in such conditions will cause the road area to be narrow, so that it will cause congestion, queues, slow movement of vehicles, even accidents. so that researchers need to do research on "Performance Analysis of Four Unmarked Intersections Using Indonesia Road Capacity (Kapasitas Jalan Indonesia: KAJI) Applications (Case Study: Simpang Seringgu in Merauke Regency)". 2. RESEARCH METHODOLOGY This research is quantitative descriptive. The study was conducted at four unmarked intersections a week by taking vehicle volume data and side obstacles for a week during peak hours. The tools needed in this study are roll meters, traffic counters, handy talkies, and stationery. For vehicle enumeration, vehicle data is taken at 15-minute intervals with vehicle classification according to the 1997 Indonesia Road Capacity Manual, namely light vehicles or Light Vehile (LV), heavy vehicles or Heavy Vehicles (HV), motorbikes or Motor cycles (MC) and no vehicles motorized or Unmotorozed (UM). 3. RESULTS AND DISCUSSION 3.1. Survey Results The following is a survey of traffic volume at a four-week intersection in Merauke Regency editor@iaeme.com
