Prioritization of Road Network Construction in Bacan Island of North Maluku Province

Bacan Island, located in South Halmahera, North Maluku Province, is a potential region with a variety of important sectors, such as plantations, fisheries, mining, tourism, industry and trade. Until recently, this potential has not been exploited fully due to lack of transportation infrastructure systems. The government has prepared the plan to construct the road network systems, which consist of five road segments connecting the potential regions. With limited funding available, it would be impossible to build the road in the same time. Therefore, an optimum and carefully planned prioritization program should be applied. The purpose of this study was to determine the priority of road construction on the island of Bacan using Important Performance Analysis and Analytical Hierarchy Process methods. The result shows that the criteria considered important in determining the prioritization of road construction are as follows: (a) accessibility, (b) linkage, (c) land use, (d) cost, (e) technical aspects, (f) economic, and (g) environment. It is recommended that the construction phases of the road network in Bacan Island are Labuha-Babang, Babang-Songa, Songa-Wayaua, Labuha-Sawadai, Sawadai-Kubung, Babang-Yaba, Labuha-Belang-belang, Belang-belang-Yaba, Songa-Wayatim, and Wayatim-Wayaua, consecutively

Pengaruh Penambahan Aditif Terhadap Kinerja Campuran Beraspal Porus

One of the challenges in implementing the porous asphalt mix is its low stability, which in some cases as low as 500 kg, making it hard to be implemented even in the collector road system. The objective of the research is to evaluate addition of Gilsonite and Latex additives to the porous mix, in search of better or higher stability. Evaluation in this study follows the Marshall procedure. The result shows that adding Gilsonite increases mix stability up to 900 kg and it also performs better compared with the latex-added mix. However, it reduces the permeability capability of the mix, for some points. In the future, further research could be conducted to evaluate gradation modification for increasing its permeability

Evaluasi Dan Potensi Pengoperasian Bus Sekolah (Studi Kasus : Bus Halokes Kota Malang)

EVALUASI DAN POTENSI PENGOPERASIAN BUS SEKOLAH (STUDI KASUS : BUS HALOKES KOTA MALANG)Evaluation And Potential Operation Of School Bus(Case Study: Bus Halokes Poor Town)Tony Prasetyo1, Ludfi Djakfar2, Sobri Abusini31,2,3 Jurusan Teknik Sipil, Fakultas TeknikUniversitas BrawijayaAlamat korespondensi : Jln. MT. Haryono, Malang, Jatimemail: [email protected] is a city with a high population density about 8129 people /km2. Malang city is known as a tourism and educational city. The high population and many activities causes a traffic jam in Malang. To reduce the traffic jam and help students reduce using private motorcycle, Malang goverment provide some free school bus for students. The method used in this research is descriptive quantitative analysis with the description of public transport operational performance analysis and analysis of vehicle operating costs. It also used SWOT method to determine the performance of the school bus, potential, problems and strategies used to develop a school bus. The results showed that operational performance is good with load factor value less than 1 every segment. The travel speed average is 40 km / hour about 40 until 60 minutes. The service time is about two times in every morning and afternoon and the waiting time of passengers between 5 to 10 minutes. The results of BOK calculation is Rp145.579,- a day which is subsidized by the government of Malang city. Based on the user's perception of school buses, the most important factors considered are comfort, safety and reliability. Based on SWOT calculations, the development strategy contained in a space that is rapid growth strategy that harnesses the strength and the opportunities.Keyword : School buses, operational performance, BOK, SWOT, development strategyAbstrakKota Malang merupakan kota dengan kepadatan penduduk yang tinggi mencapai 8.129 jiwa/km2. Selain sebagai kota wisata, kota Malang juga dikenal sebagai kota pendidikan. Tingginya kepadatan penduduk Kota Malang sejalan dengan beragamnya aktifitas yang ada menyebabkan terjadinya kemacetan di Kota Malang. Untuk mengurangi kemacetan dan membantu pelajar mengurangi penggunaan kendraan pribadi, pemerintah Kota Malang menyediakan bus sekolah gratis bagi para pelajar. Penelitian ini bertujuan untuk Evaluasi kinerja bus sekolah menggunakan metode Analisis Deskriptif serta analisis biaya operasional kendaraan serta metode SWOT untuk mengetahui kinerja dan strategi. Hasil penelitian menunjukkan bahwa kinerja operasional kendaraan cukup baik dengan nilai load factor kurang dari 1 per segmen dengan kecepatan perjalanan rata-rata 40 km/jam dan waktu tempuh 40-60 menit. Waktu pelayanan 2 kali yakni berangkat dan pulang sekolah dengan waktu tunggu penumpang antara 5 sampai 10 menit. Sementara itu hasil perhitungan BOK adalah Rp 145.579,- per hari yang disubsidi pemerintah. Berdasarkan persepsi pengguna bus sekolah Kenyamanan, keamanan dan keandalan adalah faktor yang dirasa paling penting. Berdasarkan hasil perhitungan SWOT, strategi pegembangan terdapat pada ruang A yaitu rapid growth strategy yakni strategi pertumbuhan cepat dengan memanfaatkan kekuatan dan peluang yang ada

Evaluation of Road Roughness and Road Deterioation

There are two road condition survey methods commonly used, the roughness-based equipment such as NAASRA and the distress and severity type road evaluation method as presented by ASTM D-6433. The objective of the study is to evaluate the relationship between road condition obtained from roughness type equipment and road distress. To achieve the objective, a condition survey using the two methods were performed on two road segments in the East Java Provincial road system. Data obtained from the field was evaluated to obtain International Roughness Index (from NAASRA) and Present Condition Index value (from field condition survey). The results show that the two methods provide a comparable result when the distress type is of un-even surface such as rutting and bumping. A slight different result is observed when the major distress occurred in the road is of crack-type such as fatigue and block cracking

Pengaruh Oli Bekas Dengan Solar, Minyak Tanah Dan Waktu Pemeraman Pada Perkerasan Daur Ulang

Perlunya inovasi dalam pemeliharaan jalan yang ramah lingkungan, pengolahan bahan tidak terpakai serta menggurangi pemakaian material baru maka digunakanlah perkerasan daur ulang yang dapat mengembalikan kekuatan perkerasan. Untuk mengembalikan kekuatan perekerasan daur ulang dibutuhkan peremaja. Peremaja yang digunakan yaitu oli bekas dan solar serta oli bekas dan minyak tanah dengan perbandingan oli bekas : solar dan oli bekas d: minyak tanah yang sama yaitu 0 : 100, 25 : 75, 50 : 50, 75 : 25, dan 100 : 0 dengan kadar peremaja yang dicampurkan 4% terhadap berat benda uji. Metode penelitian yang digunakan dalam penelitian ini yaitu metode grafik. Berdasarkan hasil dari metode tersebut solar dan minyah tanah tidak berpengaruh terhadap stabilitas benda uji. Perbandingan proporsi bahan peremaja dengan bahan pelarut solar untuk mendapatkan nilai stabilitas optimum perkerasan daur ulang adalah 100 : 0, dengan pemeraman 6,8 hari, diperoleh nilai stabilitas optimum 131,92 kg. Sedangkan perbandingan proporsi bahan peremaja dengan bahan pelarut minyak tanah untuk mendapatkan nilai stabilitas optimum perkerasan daur ulang adalah 100 : 0, dengan pemeraman 9 hari, diperoleh nilai stabilitas optimum 138,6 kg. Dari nilai stabilitas benda uji yang diperoleh, nilai stabilitas benda uji tidak memenuhi standar Laston maupun Latasir

Permodelan Kebutuhan Transportasi Massal Guided Busway Menggunakan Structural Equation Modeling

Transportation problem is complex because the growth of road infrastructure is not proportional to the increase in the number of travels. This is indicated by the increasing levels of private vehicle ownership, numer of trips, insufficient of public transport services, and limited road infrastructure. In this study, the pattern of mass transit, as stated in Law No. 22 of 2009, was examined. Analyses were performed using Confirmatory Factor Analysis and Structural Equation Modeling. The results showed that the variables of Travel Origin and Destination, Travel Patterns, Willingness, and Ability to Pay explained approximately77.0% of the variation in the Guided Busway Needs variable. In addition, Travel Origin and Destination, Travel Patterns, and Willingness and Ability to Pay have positive and significant impact on the Guided Busway Needs
