This study attempts to model freight transportation of specific commodity in the regional scale, particularly to identify the shortest route of Crude Palm Oil (CPO) commodities, which are transported from factories to ports using different transportation network and mode. Several activities were performed, includingidentifying the location of palm plantations and factories supporting CPO industries, identifying intermediate points in the road and river networks, and determining the access route of CPO transportation from factory to the road or river networks. In determining the shortest route, various transportation networks and modes are simulated using Geographical Information System analysis by considering travel distance, time, and costas the variables influencing transportation systems. There are 113 of CPO factories identified, then be classified into three classes by considering their production capacity. It is found that 80 factories are classified as small (71%), 26 factories are medium (23%), and 7 factories are big (6%). The shortest route is identified through both road and river networks. The analysis of the shortest routes shows that road networks have shorter travel distance and time compared to the rivers. Nevertheless, river transportation offers a cheaper price compared to road transportation. Therefore, there is a competition between these two transportation modes, in which about 51% of factories probably use road networks and 49% use river networks. Moreover, it is predicted that about 70% of total CPO in Central Kalimantan is transported to Sampit port and only 30% is transported to Kumai port.Keywords: freight transportation, shortest route, Geographical Information System

The development of Special Region of Yogyakarta has been occuring rapidly due to this region is well known as student city and the primary tourism destination in Indonesia. One of the transportation problems related to the tourism activities is traffic conflict due to parking area of tourism bus in Ngabean, Yogyakarta City. Therefore it is needed to evaluate signalized junction around the parking area in order to reach the optimal performance. The study carried out among other by conducting field survey to the existing condition (performance) of signalized junction either in the weekend (Saturday) and weekday (Monday), especially by evaluating the degree of saturation (ds). The analysis results showed that the degree of saturation in the weekend is 0,89, which is higher than the allowed one (ds=0,85). Since the degree of saturation in the weekday is 0,76 so it is relatively good. The scenarios (model) applied to improve the overall junction performance are by estricting (prohibiting) left turning on red (LTOR) and by carrying out road widening. The final result obtained from the scenario (model) is the degree of saturation (ds) becomes lower than the allowed value (0,83<0,85) for all approaches in the signalized junction.Â

Kecelakaan yang terjadi antara kendaraan jalan raya dan kereta api dapat terjadi di perlintasan sebidang walaupun sudah dilengkapi dengan prasarana yang telah ditentukan. Penelitian ini bertujuan untuk menginspeksi keselamatan perlintasan sebidang di JPL 349, Jalan Timoho, Yogyakarta, karena lokasi perlintaasan sebidang ini berdekatan dengan pusat kegiatan masyarakat. Metode penelitian ini diawali dengan studi pustaka dan pengumpulan data primer dan data sekunder. Data primer terdiri dari data kelengkapan infrastruktur, data geometrik, volume lalulintas, tundaan lalulintas, panjang antrian kendaraan, dan indeks kondisi struktur perkerasan (Pavement Condition Index). Sementara itu, data sekunder berupa jadwal kedatangan dan keberangkatan kereta api. Hasil penelitian ini menunjukkan bahwa perlintasan sebidang JPL 349 tidak memenuhi persyaratan yang berlaku terkait dengan rambu, marka, interval waktu kedatangan kereta api, sudut perpotongan perlintasan, jarak antara perlintasan sebidang yang berdekatan, dan alinemen horizontal. Tundaan lalulintas terlama ialah sebesar 194 detik dan antrian kendaraan terpanjang ialah 210 meter. Selain itu, disimpulkan bahwa nilai indeks kondisi struktur perkerasan ialah sebesar 72.9% (sangat bagus).Accidents between motorized vehicles and trains may occur at level crossings even though it has been maintained and given an adequate infrastructure. This study aims to conduct a safety inspections at JPL 349, Timoho Street, Yogyakarta since the level crossing location close to the center of human activity. This research method begins with a literature study and primary and secondary data collection. The primary data consisted of infrastructure completeness data, highway and rail track geometric, traffic volume, traffic delay, vehicles queue length, and pavement condition index (PCI). While secondary data was in the form of train departure and arrival schedules. The conclusions of this study stated that the JPL 349 level crossing do not meet the applicable regulatory standards in terms of signs, markers, train travel time intervals, intersection angles between highway and rail track, and the distance between level crossings. In terms of geometric, the horizontal alignment of the highway was also not in accordance with the applicable regulations. The longest traffic delay was 194 seconds and the longest queue of vehicles was 210 m. In addition, it was known that the average PCI was 72.9% (very good).
