Abstract

Abstrak Perkerasan lentur suatu jalan harus mempunyai kinerja yang baik sehingga dapat melayani beban kendaraan selama umur rencana. Oleh sebab itu dibutuhkan suatu bahan tambah yang dapat meningkatkan kinerja suatu perkerasan. Salah satunya adalah Retona (Refined Buton Asphalt). Kinerja suatu perkerasan dapat ditentukan dari pengujian dengan metode Marshall yang menghasilkan parameter stabilitas, pelelehan, kerapatan, rongga dalam campuran, rongga di dalam agregat, dan Marshall Quotient.Penelitian ini bertujuan mempelajari karakteristik campuran beton aspal menggunakan bahan tambah Retona. Campuran beton aspal menggunakan kadar Retona 0% hingga 2% dengan interval penambahan 0,5% terhadap berat agregat kering pada kadar aspal desain. Setelah itu dilakukan analisis data dari parameter Marshall yang diperoleh dengan menggunakan pengujian statistik. Material yang digunakan adalah agregat dengan gradasi yang terdapat pada laporan PUSLITBANG Prasarana Transportasi mengenai Retona, dan bahan pengisinya adalah abu batu. Bahan pengikat yang digunakan adalah aspal minyak yang memenuhi spesifikasi penetrasi 80.Kadar penambahan Retona pada campuran beton aspal yang memenuhi persyaratan Bina Marga adalah 0,5%. Seluruh nilai parameter Marshall pada campuran dengan kadar Retona 0% dan 0,5% secara statistik tidak berbeda. Berdasarkan hasil tersebut, maka Retona sebagai bahan tambah yang kadar penambahannya berdasarkan berat agregat kering tidak direkomendasikan untuk digunakan pada campuran beton aspal.Kata-kata kunci: retona, parameter Marshall, berat agregat kering.

Abstract

Speed humps are speed limiting devices to protect pedestrians and reduce the accident rate. The installation of speed humps in residential can reduce the speed of motorists but, at the same time, also can create a problem. The purpose of this study is to analyze the noise level caused by installation of speed humps and to compare noise levels before and after vehicle crossed the speed humps. The results show that the noise levels caused by vehicles after passing the speed hump are higher that those before the hump. The average noise levels at distances of 50 m and 10 m before the speed hump are 64.15 dBA and 63.63 dBA, respectively. These values increase to 66.64 dBA and 69.89 dBA at distances of 50 m and 10 m after the speed hump. It is also found that the noise levels for different location and time of measurement are significantly different.Keywords: speed humps, noise level, speed limiting device.

Abstract

Abstrak Agar dapat dihasilkan suatu perkerasan jalan dengan mutu yang baik, maka aspal yang digunakan harus mempunyai kualitas yang baik pula. Kualitas aspal dapat dinilai dari keseragaman (keajegan) hasil pengujian sifat-sifat aspal keras. Salah satu sifat aspal yang penting adalah sifat kecairan aspal keras (konsistensi). Untuk menganalisis keseragaman tersebut, maka dilakukan pengujian aspal terhadap aspal produksi dalam negeri sebanyak sepuluh sampel. Pengujian-pengujian yang dilakukan adalah uji berat jenis sebanyak dua buah benda uji untuk setiap sampel, uji penetrasi pada temperatur 25°C sebanyak tiga benda uji untuk setiap sampel, uji viskositas pada temperatur 60°C, 135°C, dan 140°C masing-masing sebanyak dua benda uji untuk setiap sampel.Metode Pengendalian Kualitas digunakan untuk menganalisis keseragaman aspal keras produksi dalam negeri tersebut. Dalam metode ini sarana yang digunakan adalah diagram pengendalian kualitas. Hasil analisis menunjukkan bahwa nilai penetrasi yang diperoleh dari hasil pengujian sudah berada dalam rentang yang disyaratkan Bina Marga. Jika nilai penetrasi ditinjau dengan diagram pengendalian kualitas juga dihasilkan nilai yang seragam. Berdasarkan pengendalian kualitas untuk hasil pengujian viskositas pada tiga temperatur yang diuji, dihasilkan nilai yang tidak seragam. Diagram pengendalian kualitas untuk hasil uji berat jenis menunjukkan adanya keseragaman nilai hasil pengujian. Jadi aspal yang diuji tidak konsisten/ajeg/seragam menurut analisis pengendalian kualitas, namun memenuhi spesifikasi Bina Marga.Kata-kata kunci: analisis keseragaman, aspal, uji viskositas, uji penetrasi, uji berat jenis, konsistensi

Abstract

The provision of bus rapid transit (busway) in Jakarta aims to provide a high service quality of publictransportation, to reduce congestion, and to improve the transportation system. In fact, the success of publictransportation depends on the acceptance and loyalty of the user. The image and experience of the userregarding the service quality also has a significant influence. Thus, the aim of this study is to explore therelations among constructs, i.e. user loyalty, image, and experience regarding the service quality of BRT.Responses from the user in the first corridor of BRT system was analyzed using structural equationmodeling. The results show that high image owned by the users regarding the service does not necessarilymean a high loyalty shown by the users. Analyses confirm the support of perceived service quality on theloyalty of the user in the future.Keywords: loyalty, image, fact, quality of service, busway

Abstract

The coordination among institutions responsible for recording road accident data is weak. It is shown that thefatal accident data for specific locations and/or time periods are reported differently by police offices,insurance companies, and provincial office of health. The aim of this study is to eliminate the difference inthe reported fatal accident data by developing a uniformity method. The proposed method would be able tohandle parallel conversion for adjusting fatality data from the three institutions. The conversion factor willemploy the combination of average values of the parallel conversion factors. Based on the data available inthe Province of West Java, it is found that the value of parallel conversion factors between the police officeand the West Java Provincial Office of Health is 1.31 and between the police office and Jasa Raharjainsurance company is 3.93. The average value of these conversion factors with insurance claim considerationis 2.56 meaning that the real number of fatalities is 2.56 times the amount recorded by the police office.Keywords: road traffic accident, fatalities accident data, and parallel conversion factor

Abstract

Abstract The aim of this study is to explore the effect of motorization to the development of urban public transportation in urban areas in Indonesian city in the last decade. The study employs many statistical data regarding motorization and urban public transport. It can be concluded that the motorization will continue to grow, and the existing transport policy should be re-questioned. It roots on the lack of acceptable provision of public transport in term of quality and quantity, but also as a result of high preference on using private transport. The challenge becomes excessive and complex, since there is no appropriate visionary road map for development of urban public transport. In answering this problem, the authors propose an abstract of two sequence approach, namely setting priority in taking side in provision of acceptable mobility for all, and followed with the redefinition of urban transport development by implementing transit-oriented development.Key words: motorization, urban public transport, development, sustainability.

Abstract

Abstract Travel, most often viewed in theory as derived from the demand for activity participation, has almost always been modeled on the trip-based basis, i.e., the trip is treated as the unit of analysis. Attributes of a trip (e.g., its origin and destination, mode, length) have been the subjects of analysis, but not the types of activities engaged in, their durations, sequences, and timing. This paper offers a brief review of the travel behavior analysis in order to provide a better understanding and forecasting of travel behavior. The article further offers discussions on its possible applications in urban areas of developing countries where historical accumulations of transportation and communications technologies are being introduced within a short span of time, creating the environment for travel which may not be properly accounted for using the conventional trip-based models of travel demand. In addition, the dataset from Malaysia was employed as a case of study.Keywords: travel behavior, travel, demand, transportation planning, developing cities.
