Abstract

Bus Rapid Transit (BRT) has been one of the most popular transit mode which provides fast and easy access to meet the transportation needs in developing country. It offers the opportunity to create a high-quality mass transit system at affordable cost, which is particularly important for developing countries. Despite of many BRT systems have been implemented in various cities in developing countries, there are a limited number of studies exploring how to increase BRT's ridership. The main goal of this study is to gain insights of Transjakarta and DKI Jakarta's government strategy to improve the BRT performance. It is important to examine the Transjakarta dan DKI Jakarta's government implemented strategies of BRT system along with the policy reforms analysis that affects the ridership. Furthermore, this study also intends to enhance the understanding of the underlying acts that may influence on BRT ridership. Therefore, these act forms can be used as a benchmark for implementing BRT systems in other cities in Indonesia. For this purpose, conceptual frameworks, explaining the relationship between the daily BRT ridership and the potential factors, are developed using information collected from the operational of TransJakarta. This study captured the ridership patterns and data during the last 3 years, from 2017 to 2019. Transport integration as well as increasing network and number of fleets are found to be the main factors which can boost the ridership. In addition, the research presents some inputs to formulate some development strategy for operating BRT which can be applied in other cities, especially in Asia.

Abstract

This research shows that the average number of passengers during the implementation of the PSBB is reduced by 50%, although there are still some Koasi K01A whose number of passengers exceeds the health protocol standard recommended by the government. Respondents considered the feasibility of the K01A Koasi to operate as still quite feasible, because there were still some respondents who still needed this Koasi K01A to travel so that it could be judged that the K01A Koasi was still feasible to operate to serve its passengers, only had to replace the old Koasi units with a newer unit that provides comfort for Koasi K01A passengers. The comfort and safety provided by the K01A Koasi manager are still considered very uncomfortable and safe by respondents.

Abstract

As the population continues to grow, it results in a lot of human mobility. However, the high mobility is not matched by transportation facilities and infrastructure services, especially the sidewalks. One of the areas with existing sidewalk problems is Bekasi Highway KM. 18. The problems that occur are that the sidewalks are used as a place to sell street vendors, are used as illegal parking lots and the unavailability of guide tiles for persons with disabilities. The methodology of this research is carried out by conducting geometric surveys, measuring the volume and travel time of pedestrians to determine service levels and distribute questionnaires to 63 respondents to pedestrians in finding the level of performance and the importance of sidewalk facilities. The processing of this data uses Microsoft Excel and the Statistical Package for the Social Sciences (SPSS) using the Importance Performance Analysis (IPA) method. The results of the analysis carried out by geometric surveys show that the sidewalks have not met the minimum standards according to regulations. From the measurement results of the volume and travel time of pedestrians, the service level is obtained with category B, as well as the results of the questionnaire related to the level of performance and the importance of sidewalk facilities, namely quadrant I there is Circulation, Climate, Shape, Safety, Cleanliness, Beauty, in quadrant II there is Circulation, Noise, Smells, Cleanliness and in quadrant III there is Circulation, Noise, and Cleanliness.

Abstract

The need for transportation has now become a very meeting thing for residents of a city. Because transportation is a very important means of smoothing the economy of a region. Along with the growing economy of residents in an area, the number of owners and users of private vehicles has also increased rapidly. That needs to be balanced with supporting transportation support facilities. For that we need a solution to reduce congestion by maximizing the benefits of public transportation such as commuter line trains. One thing that can be done is the construction of a Park and ride building as a transportation support facility at Bekasi Station, Bekasi City. To plan a Park and ride building some data is needed. Data obtained from field surveys, namely surveys to obtain the demand value for the arrival of vehicles. The survey was conducted by counting the number of vehicles leaving and entering the Bekasi station parking lot which is divided into two zones, namely the northern zone and the southern zone. The survey was carried out at 06.00 – 21.00 WIB. In the results of data processing using excel, it is obtained the characteristics of Park and ride facilities users and also the number of users demand for park and ride facilities for motorbikes is 676, while for cars is 107 vehicles. of the total demand, a park and ride building is planned to accommodate 1000 motorbikes and 100 cars with 3 floors.

Abstract

Concrete generally composed of four main constituent materials namely portland cement, fine aggregate (sand), coarse aggregate (gravel), and water. The large amount of use of concrete in construction results in an increase in the demand for concrete materials, thus triggering the mining of concrete materials on a large scale which caused the decline in natural resources in Indonesia for the need for concrete material. If needed, substitute materials can be created in such a way as to change certain properties of concrete to function better, economically, and environmentally friendly. The waste of fly ash and shells of blood clams can be used as a substitute for cement, coarse aggregates and fine aggregates. The purpose of this research is to determine the compressive strength of the variation of the percentage of fly ash substitution with cement and shells of blood clams with coarse and fine aggregates and the addition of superplasticizer to the compressive strength of concrete. The research is using experimental methods, test specimen samples will be tested for workability, density, and compressive strength. Variable in the research are (1) related variables : density and compressive strength, (2) independent variable : variation of 0%, 5%, 10%, and 15% of blood clam shell needs of the total weight of coarse aggregate. Based on the results of the research concluded that (1) Slump value of the samples 0%, 5%, 10%, and 15% consecutive is 97mm, 89mm, 151mm, 149mm. (2) density of concrete with substitution of blood clam shells with coarse aggregate with samples 0%, 5%, 10%, and 15% consecutive is 2284 Kg/m3, 2308 Kg/m3, 2297 Kg/m3, and 2293 Kg/m3. (3) Testing of concrete compressive strength at 28 days with substitution of blood clam shells with coarse aggregate with samples 0%, 5%, 10%, and 15% consecutive is 21.44 Mpa, 24.38 Mpa, 19.02 Mpa, and 19.34 Mpa. The composition of substitution of blood clam shells with coarse aggregate of 5% has a higher compressive strength than other compositions.

Abstract

Palm fibers are natural fibers that are difficult to rot because there is no decomposer that can decompose the fibers. In addition, in Indonesia there are a lot of palm plants where the fibers are taken from the tree. The charcoal briquette powder is the fine grains of briquette charcoal that is mashed and contains silica. This study aims to determine the effect of using palm fiber as an added material for fiber and charcoal briquette powder as a substitute for cement in the concrete mixture on the compressive strength of concrete. This study uses a mixture of palm fiber as much as 0.75 %, 1.50 %, 1.75 % and 2.75 % from the weight of fine aggregate, as well as charcoal briquettes powder 5 %, 5 %, 10 %, and 15 % of the weight of cement. The compressive strength test was carried out on the 7th, 14th, 21st, and 28th days. The highest compressive strength value was obtained in variation V.2 with a mixture of 2.75% palm fiber + 5% briquette charcoal powder on the 21st day of testing of 20.02 Mpa
