The problem is caused by many factors, namely high population, high use of the private vehicle, inadequate current public transport supply, urban sprawling, etc. The government, both City and National Government has been formulating and implementing a plan to develop sustainable transportation that serves the citizen of Jakarta Metropolitan Area. This included the operation of Jakarta Bus Rapid Transit, KRL Commuter Line and Jakarta Mass Rapid Transit. In the near future, both inner city and metropolitan light rapid transit will also operate in this area. This paper reviews the development and challenge of the transportation system in Jakarta Metropolitan Area and proposes a recommendation to optimize the current transport system. In general, there are three components that should be considered to achieve sustainable transportation. Those components are i) strong transport authority, ii) integrated master plan, iii) Sustainable Resources, Funding, and Financing.","PeriodicalId":274835,"journal":{"name":"International Journal of Sustainable Transportation Technology","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125885952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First popularized by the Mayor of Paris in 2020, 15-Minute City is an evolving concept that derived from its predecessors such as neighborhood-unit planning and walkable city. This paper explores the implementation of the 15-Minute City concept in city planning by using Singapore as the case study. In 2018, Singapore released its Land Transport Master Plan 2040 and which includes an ambitious concept of 20-Minute Towns and a 45-Minute City (2MT45MC) and has similar ideas to the 15-Minute City concept. Through various journal articles and media coverage, Singapore’s policy and regulation regarding its transport planning were thoroughly reviewed to find Singapore’s strategy and challenges in realizing the objective of its 2MT45MC concept. Normalizing active mobility and enhancing connectivity nationwide are the main strategies to overcome the biggest challenges faced: lack of legal backing in personal mobility devices and the country’s rigid zoning. Even though it is too early to say whether 2MT45MC is achievable or not, projects such as the North-South Corridor show that for a long-term plan, it seems feasible.","PeriodicalId":274835,"journal":{"name":"International Journal of Sustainable Transportation Technology","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125187474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to analyze the fleece performance as a friction component material in brake pads. The fleece was initially pre-treated by heating for 4 hours at 150°C and cut into 2 mm sizes. The epoxy resin and hardener were mixed with a ratio of 1:1. The 0.5 g pre-treatment fleece was added to the resin mixture, so the total mass of the resin-fleece mixture was 12.5 g. The mixture was then molded into a cube mold (dimensions of 2.5 × 2.5 × 2.5 cm). The brake pad was dried at room temperature for a day. The characterizations were done using the compressive strength and puncture strength test. The results showed that the fleece brake pad has good mechanical characteristics, demonstrated by the pressure of 215 MPa, which can still be held by the surface of the fleece brake pad. The puncture test showed an average puncture of 76.43%. Overall, the fleece shows good performance on the brake pads. Fleece has many minerals that make it as powerful fiber characteristics and prospective as a friction component material on the brake pads. This research is expected to provide new information about organic materials for friction materials in brake pads.","PeriodicalId":274835,"journal":{"name":"International Journal of Sustainable Transportation Technology","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122171560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
