Abstract

Ellips Errors were constructed to analyse pedestrian accidentsconcentrations in Newcastle, England. More specifically, Ellips Errors were used toanalyse both spatial and temporal patterns of pedestrian accidents. Having observedthese patterns, cyclic pedestrian accidents would be able to be identified. The studyresults showed that high accident concentration occurred in the Newcastle citycentre area. These were indicated with both centroids and distributions (shown asellips area) of pedestrian accidents. Top priority on pedestrian accidents reduction,therefore, should be paid more on the city centre area. The best result for using thisEllips Error method in Indonesia will be achieved through integrated road accidentsrecording system by means of Global Positioning System (GPS) and GeographicInformation System (GIS). Geographic position of road accidents and detailedmaps of the urban area, i.e. 1:1000 on scale, are required for this Ellips Errormethod.

Abstract

Desa Bugbug terletak di Kabupaten Karangasem dengan jumlah penduduk 2068 KK dengan 10101 jiwa (data Desa Bugbug). Terdapat variasi penghasilan masing-masing keluarga dan bahkan ada yang masih kategori KK miskin. Akan tetapi desa masih memiliki aset tanah yang cukup banyak yang bisa diberikan kepada masyarakatnya untuk dijadikan perumahan (pekarangan). Untuk mengurangi ketimpangan dalam kehidupan itulah Desa Adat Bugbug memprogramkan pemberian tanah untuk perumakan (pekarangan) kepada masyarakat Bugbug yang tidak mampu (KK miskin) dengan tujuan untuk meningkatkan taraf hidupnya. Agar sesuai dengan rencana pengembangan Desa Bugbug ke depan, maka diperlukan suatu tata letak kawasan pemukiman yang berwawasan kearifan lokal, sehingga perlu penataan jalan induk, jalan anak induk, gang, drainase dan sebagainya, agar kawasan tersebut bisa kelihatan asri dan tertata rapi. Namun di lain pihak Desa Adat Bugbug tidak memiliki tenaga ahli dalam hal penataan kawasan pemukiman. Tujuan pokok dari pengabdian masyarakat ini adalah menata kawasan pemukiman penduduk di Bugbug Karangasem yang berwawasan kearifan lokal dengan melakukan perencanaan teknis kawasan. Kegiatan yang dimaksud meliputi pengukuran dan pemetaan topografi rencana kawasan serta fasilitas pendukung seperti perencanaan lokasi jalan dan drainse. Hasil dari penataan ini adalah peta layout yang memuat informasi lokasi dan lebar jalan akses dan jalan lingkungan, lokasi dan luas kapling. Evaluasi hasil dilakukan oleh para pemuka Desa Adat.

Abstract

Abstrac :Road handling priority determination is an important tasks faced by decision makers and is regarded as a complex multi-criteria problem. It requires a system to categorise and ranks the project order using several criteria. Officially, SK. No. 77 of the Directorate General of Highway issued in 1990 is a method used in the local government. This method however, has been considered to have limitations to determine road handling priority. Using previous studies, the Analytic Hierarchy Process (AHP) and the combination of FAHP and TOPSIS methods are considered relevant to determine road handling priority. These methods incorporates a variety of criteria which can also be considered by the decision makers. Using the AHP, the criteria of road conditions, traffic volume, economic and policy factors are 41.8%, 25.4%,  21.6 and 11.2% respectively. Meanwhile, a combination methods of FAHP and TOPSIS give the criteria of road conditions, traffic volume, economic and policy factors of 33.8%, 26.6%, 24.7% and 14.9% respectively. Both AHP and FAHP produce the same result in terms of criteria rank. This is not the case however, in the sub criteria rank. This study found that AHP gives road handling priority differently to the SK. No 77 of Directorate General of Highway (1990). In contrast, a combination methods of FAHP and TOPSIS produces road handling priority in the same way to the SK. No 77 of Directorate General of Highway (1990). Denpasar city government is suggested to consider the use of FAHP and TOPSIS method in determining its road handling priority. This method is considered to have a capability to combine many criteria using a priority weighted score. The road handling priority results therefore, are more realistic.

Abstract

The population increase in Denpasar City causes the increase of peoples’ activities which is followed by the increase of using transportation facilities. It certainly influences the traffic in the city itself. One of the peoples’ activities causing traffic jams on the streets of Denpasar particularly on Gunung Agung Street is the students’ pick-up service. The jam is mainly caused by the use of private vehicles especially motorcycles for picking-up the students. The problem can be overcome with pick up service so that the use of private vehicles can be minimized. Some advantages can be gained from the pick-up service; it can be done door to door in accordance with the students’ schedules and it can help the parents who are in troubles in bringing and picking-up their children to schools. A planning and an evaluation on aspects of financial investment feasibility towards the students’ pick-up service are needed in order to match both the interests of service providers and the customers. This research used field survey method completed with interview method. The interview method was applied to gain primary data from related parties and from related institutions for the secondary data. Tariff calculation analysis based on the vehicle operational cost (VOC) used a method of Transportation Department, and the Ability to Pay (ATP) tariff and Willing to Pay (WTF) tariff were determined based on respondents’ income and their perceptions toward a tariff they expected. The result of the research shows that the ATP tariff for both routes is higher than WTF tariff; on route I the ATP is Rp. 569,76 per kilometer-  passenger (Rp. 4,273 per passenger) and the WTP tariff is Rp. 499,67 per kilometer-passenger (Rp. 3,748 per passenger), on route II the ATP tariff is Rp. 594,46 per kilometer-passenger (Rp. 3,864 per passenger) and the WTP tarrif is Rp. 554,56 per kilometer-passenger (Rp. 3,605 per passenger). Based on the estimation of the passengers, there are 97 vehicles estimated for route I and 38 for route II. Based on the tariff analysis, it can be recommended that tariff based on VOC + 15% margins is Rp. 797,47 per kilometer-passenger (Rp. 5,981 per passenger) for route I and Rp. 1,645,08 per kilometer-passanger (Rp. 10,693 per passenger) for route II. The financial evaluation analysis shows that the three criteria such as Net Future Value, Benefit Cost ration, and Internal Rate of Return for route I and route II are not feasible to be operated if they are operated both by personal and corporation agents.

Abstract

The present transport activities cause negative effects in the form of various kinds of diseases in the community. The government in this case, it makes use of the guidelines Noise Reduction Building (BPB) to reduce traffic noise. BPB in the design of Highways made ??of konblok ALWA (Artificial Low Weight aggregate) with a height of 2.75 meters was built along the road at a distance of 5 meters from the edge of the pavement. In this study, the noise level will be analyzed without and with unobstructed BPB. This study began from site selection studies, problem identification, goal setting research, development BPB, measuring noise levels without and with BPB analysis of the data and draw conclusions. From the analysis of the results obtained by calculation that the path chosen as the object of study, namely Jalan Uluwatu II Jimbaran without BPB has a noise value of 73.23 dB (A). While the values ??obtained BPB 61.85 decibels A, the value of this noise then most of the raw noise threshold has been exceeded so that some kind of designation of the area should be kept lying on the edge of the pavement. From the calculation of the distance from the edge of pavement to reduce noise levels in order to be secure appropriate noise threshold obtained for the allotment of residential, hospitals, schools and places of worship should be within 24.29 meters from the edge of the pavement. For government offices, public facilities should be located at a distance of 6.79 meters, while for offices, commerce, industry, services and stations could be placed as close as possible but still within the protection of BPB.

Abstract

By Pass Ngurah Rai is the only primary arterial road linking the traffic flow of people and goods from Ngurah Rai Airport to Nusa Dua. Peak hour traffic flow condition has exceeded the capacity of the road. To solve the above problems, it is planned to build toll roads Benoa-Bandara-Nusa Dua. The objectives of this study were to analyze the performance of existing roads with and without the toll road, the rates applicable to service users and to analyze the financial feasibility of the investment of the project.   Analysis was performed for several scenarios, including the scenario-1, assuming traffic growth factor of i = 9.96% / year, the interest rate 16% / year, inflation accounted for 8.506% / year and the toll rates using rates set by the Jasa Marga. All of the cost including land acquisition and construction costs were provided by investors. It was found that for the scenario-1, the  NPV is Rp 1,586,137,984,347, -, BCR: 0.4754 and IRR 3, 8676%. The results of the financial analysis indicated that investment of the toll roads Benoa-Bandara-Nusa Dua is not financially feasible. In order for this project to be financially feasible, the growth rate of vehicles should be at least i = 14.7% / year.
