AbstractÂ In a complex system, such as in the field of transportation safety, the problem is actually present in the basic structure of the system. Therefore, an analysis of the system is needed to solve the problems in a comprehensive manner. For this reason, a systems approach is highly demanded. The systems approach is not just a matter of theory but also the practical way of thinking and philosophy in solving a problem. System dynamics model presents a set of cohesive steps to be followed systematically by understanding the root or basic cause of any problems under consideration. By providing insight into the feedback process, system dynamics models provide a better understanding of the users of the system to understand the dynamic behavior of a system. Keywords: system dynamics, systems approach, model, transport safetyÂ Â AbstrakÂ Dalam suatu sistem yang kompleks, seperti dalam bidang keselamatan transportasi, permasalahan sebenarnya terdapat pada struktur dasar sistem tersebut. Oleh karena itu, analisis terhadap sistem dibutuhkan untuk dapat menyelesaikan permasalahan secara komprehensif atau diperlukan suatu bentuk penyelesaian yang menggunakan pendekatan sistem. Pendekatan sistem bukan hanya menyangkut masalah teori tetapi juga mengenai cara berpikir dan filsafat praktis dalam memecahkan suatu masalah. Model dinamika sistem menyajikan seperangkat langkah-langkah penyelesaian kohesif yang harus diikuti secara sistematis dengan memahami akar atau penyebab dasar setiap permasalahan yang dipertimbangkan. Dengan memberikan wawasan dalam proses umpan balik, model dinamika sistem memberikan pemahaman yang lebih baik kepada pengguna sistem untuk memahami perilaku dinamis suatu sistem.Â Kata-kata kunci: dinamika sistem, pendekatan sistem, model, keselamatan transportasi

Rail transportation is a mass transportation mode which needs high investment. Conventionally railway operation financing comes from government funds. However, the current financing of railway operation can come from the private sector. This is in line with Law No. 23 of 2007 stating that the private sector can play a role in railway operation, there should be a separation between the role of the regulator and the operator, and the elimination of monopoly in railway operations. The railway operations offered to the private sector could be through Public Private Partnership (PPP) scheme, which needs a set of criteria so that the project could benefit the government as well as the private parties. This study aims to develop criteria to be used as the base for decision making in the selection of PPP projects in the field of railways. These criteria are divided into two groups namely Must Criteria (Kriteria Utama) and Want Criteria (Kriteria Tambahan). The data used were obtained from interview involving some respondents The results show that the criteria for the selection of PPP consists of Â 30 sub-criteria including Must Criteria, 16 sub-criteria including Want Criteria, and 4 sub-criteria that do not belong to any of those groups.Â Kereta api adalah suatu moda transportasi masal yang penyelenggaraannya memerlukan investasi yang besar. Secara konvensional pembiayaan penyelenggaraan perkeretaapian bersumber dari dana pemerintah. Tetapi saat ini pembiayaan penyelenggaraan perkeretaapian dapat bersumber dari pihak swasta. Hal ini sejalan dengan Undang-Undang No. 23 Tahun 2007, yang menyatakan bahwa swasta dapat berperan dalam penyelenggaraan perkeretaapian serta adanya pemisahan antara peran regulator dan peran operator dan penghapusan monopoli dalam penyelenggaraan perkeretaapian. Penyelenggaraan perkeretaapian yang ditawarkan ke pihak swasta dapat melalui skhema Kerjasama Pemerintah Swasta, yang membutuhkan seperangkat kriteria sehingga kerjasama tersebut dapat menguntungkan pihak pemerintah maupun pihak swasta. Penelitian ini bertujuan mengembangkan kriteria yang menjadi dasar dalam pengambilan keputusan pemilihan proyek Kerjasama Pemerintah Swasta di bidang perkeretaapian. Kriteria-kriteria tersebut dibagi menjadi dua kelompok, yaitu Kriteria Utama dan Kriteria Tambahan. Data yang digunakan diperoleh dari wawancara dengan sejumlah responden. Dari penelitian ini diperoleh kriteria untuk pemilihan proyek KPS adalah 30 subkriteria yang termasuk kelompok Kriteria Utama, 16 subkriteria yang termasuk kelompok Kriteria Tambahan, dan 4 subkriteria yang tidak termasuk keduanya yang dapat digunakan sebagai kriteria pemilihan proyek Kerjasama Pemerintah Swasta.

Abstrak: Sektor transportasi merupakan salah satu penyumbang emisi gas rumah kaca yang besar saat ini, dan menjadi tantangan besar di abad 21, khususnya dalam pengembangan pembangunan transportasi yang berkelanjutan. Inventori emisi merupakan salah satu alat yang dapat digunakan sebagai dasar pengambilan keputusan dalam permasalahan pencemaran udara. Baseline emisi dihitung di beberapa titik akurat pada jalan, yang paralel dengan proyek BIUTR. Penelitian ini dilakukan di 7 ruas jalan dalam koridor Pasteur-Cileunyi dan Ujungberung-Gedebade, untuk gas rumah kaca (CO2 dan HC), dan pencemar udara lainnya (CO, NOx, dan PM10) dari sektor transportasi. Faktor emisi Inggris dignakan dalam perhitungan beban emisi karena lebih detail dan sesuai dengan kondisi di lapangan (ragam kecepatan dan jenis kendaraan). Hasil menunjukkan skenario proyek BIUTR meningkatkan beban emisi, berkaitan dengan meningkatnya volume kendaraan. Peningkatan beban emisi yang dihitung untuk proyeksi tahun 2015-2030 dari beban emisi driving adalah (34,9 - 152,13)%, (100,94 - 441,74)%, (17,53 - 70,51)%, (12,83 - 55,5)%, dan (16,65 - 70,87) %, untuk CO2, NOx, PM10, CO, dan HC, secara berurutan. Kata kunci: Baseline emisi, transportasi berkelanjutan, pencemar udara, faktor emisi Abstract : Transportation sector as one of the biggest contributors of greenhouse gas emission, becoming one of the biggest challenges in the 21st century; especially on the way people build a sustainable transportation system. Inventory emission is one of the tools that is commonly be used as a foundation tool for decision makers in managing pollution problems. Emission baseline is calculated in some precisely exact points on the road, parallel with BIUTR project which plans to the extend to the existing and put some new fly over road links. This research was done in 7 lines of roads within the route between Pasteur-Cileunyi and Ujungberung-Gedebage. The research is focused on greenhouse gases, of CO2 and HC, and air pollutants (CO, NOx, and PM10) focusing on transportation as the source. British emission factor was used because it is the best implicated emission factors as it is better in details and the field condition, e.g. various speed and vehicle type. The results shows that BIUTR project scenario increases emission load, related to the increase of vehicles volume. The increase of emission calculated for 2015-2030 from driving emission load are (34,9 - 152,13)%, (100,94 - 441,74)%, (17,53 - 70,51)%, (12,83 - 55,5)%, and (16,65 - 70,87) %, for CO2, NOx, PM10, CO, and HC, respectively.Key words: Emission baseline, sustainable transportation, air pollutant, emission factor

More than 90% of freight movement in Indonesia is carried out by land transportation (mostly highway mode). Meanwhile most nation land is surrounded by water, in which the movement could have been carried out by sea transportation. There are rail network in Java Island and some parts of Sumatera Island where multimodal/inter-modality system can be applied. However, lack of sea and rail transportation infrastructure and management makes highway mode the main choice among other transportation modes. This study investigated the impact of overloading trucks in the freight transportation system in Indonesia, because the government still allows trucks to carry up to 50% of the normal maximum load. This policy has greatinfluence on road deterioration, creating the vehicle damage factor approximately 5 times higher than that of the normal one. This overloading has a big impact on the maintenance of the road and will increase themaintenance budget.

More than 95% of freight movement in the Province of Aceh is done by the road mode. As most of the land in the province is surrounded by sea, the freight movement could have been done by sea transportation. Railway was already in the Province of Aceh long time ago, it began to operate in 1906, but the operation was closed in 1982. The Central Government and the Aceh Provincial Government want to revitalize the railway and there is also a plan to build a new Jalan Raya from Banda Aceh to North Sumatra border. However, there is a constraint in the costs of building these infrastructures so that multimodal and intermodal transportation can not take place. As a result, road transportation remains to be a major transport choice and this condition is even worse with vehicles on the road also tend to carry overload. This study was conducted in connection with the overload effect of the freight transport using trucks and how these trucks cause road deterioration and increase road maintenance costs in the Province of Aceh. The results suggest that multimodal/intermodal freight transportation, specifically road and railroad combined transport, could provide more efficient freight transport and, most likely, is the best option for the province.Keywords: freight transportation, multimodal/intermodal transportation, overload

An important problem in urban areas is traffic congestion that occurs on the road network during the day. One cause of this problem is the high number of private car usage with low occupancy levels while public transport services are under-utilized, although the use of public transport is more efficient than that of private cars. Therefore, efforts to increase public transport use are needed to reduce transportation problems, such as traffic congestion. Mode choice is one important step in transportation modeling because this stage provides information necessary to evaluate the condition of the transportation network, including traffic congestion in the network. This model aims to determine the individual attributes and modes, which influence in selecting a mode among available modes, using the utility function parameters. Sensitivity of mode choice can be seen through the sign and magnitude of the parameters contained in this model. In this study, a simulation was conducted with a purpose to increase the market share of public transport in the City of Surakarta.Keywords: mode choice, utility function, public transport

The most common daily trip for students is the commute to and from campus. Though there are clear environmental, economic, and social drawback from using private vehicles for these trips, students still choose private vehicles to get to campus. This study reports an investigation of psychological factors influencing students’ behavior to commute by car from the perspective of the Theory of Planned Behavior (TPB). Students from three different university campuses (sample size of 312) completed a survey on their car commuting behavior. Results indicated that all relations postulated by the TPB are confirmed and perceived behavioral control was the strongest factor that influences students’ intention. Attitude, subjective norm, and perceived behavioral control explain 59% variance of the intention while intention explains 58% of the variance of the actual car use. Implications of these findings are that in order to alter the use of car, interventions should target the perceived behavioral control of commuting by car.

Downtown area is the area that located in the central of a city with a relatively close distance to the location of the activity and existing facilities and it is served by public transportation service, so that the number of private vehicles uses can be reduced. However, those conditions are not found in the downtown area of Semarang, where the number of motorcycle uses is high. That phenomenon needs to be observed from household scale as the main actors of trips. This study aims to investigate motor cycle travel behavior of households living in the downtowns area of Semarang. Based on the results it is found that husband and wife have different travel behavior along with their role in the household. Husbands have more trips related to work activities while wives have more trips related to household activities. Moreover, household travel behavior is different during weekdays and weekend. Variable which has the most influence on travel behavior in weekdays is daily activity that is accompany family members, while variables which have the most influence on travel behavior in weekend are non-daily activities such as recreation and visiting relatives. Pusat kota adalah kawasan yang menempati lokasi sentral dengan jarak relatif dekat dengan lokasi aktivitas serta fasilitas yang ada dan dapat diakses dengan jaringan pelayanan angkutan umum sehingga angka penggunaan kendaraan pribadi, khususnya bagi penduduk yang tinggal di dalamnya, dapat dikurangi. Namun kondisi tersebut tidak terjadi di pusat Kota Semarang karena angka penggunaan sepeda motor di sini cenderung tinggi. Fenomena tersebut perlu dicermati pada skala paling kecil, yaitu rumah tangga sebagai pelaku utama pergerakan. Tujuan penelitian ini adalah melakukan analisis perilaku perjalanan rumah tangga pengguna sepeda motor yang tinggal di kawasan pusat Kota Semarang. Berdasarkan hasil analisis diketahui bahwa pasangan suami dan istri memiliki perilaku perjalanan yang berbeda dalam melakukan aktivitas rumah tangga. Pergerakan suami lebih banyak dilakukan untuk kegiatan bekerja sedangkan istri lebih banyak berperan dalam aktivitas rumah tangga. Selain itu perilaku perjalanan rumah tangga pada hari kerja dan pada akhir pekan juga berbeda. Variabel yang paling mempengaruhi perilaku perjalanan pada hari kerja adalah aktivitas harian, yaitu mengantar anggota keluarga, sedangkan variable yang paling mempengaruhi pada akhir pekan adalah aktivitas non-harian, seperti rekreasi, jalan-jalan dan mengunjungi kerabat.
