Motorcycle Potential Problems in Jakarta

After the economic crisis in 1997, motorcycles become a popular transport mode in Indonesian cities.However this condition leads to large number of violation and accident rate. This study tried to discuss howthis problem started and what possible measure can be taken to solve the problems, mainly based on literaturereview. The traffic data used were compiled from the data provided by PT Pamintori Cipta. Interview surveywas conducted to find people perception of motorcycles issues. The conclusion suggests that there is a needof further comprehensive study to find out what condition that makes motorcyclists voluntary return to usepublic transport and social engineering and intensive training program should be implemented for youngergeneration to improve traffic condition in Jakarta

Koefisien Distribusi Kendaraan Untuk Perancangan Tebal Perkerasan Lentur Di Mataram, Bandung, Dan Surabaya

A comprehensive knowledge regarding vehicle distribution can be utilized to adjust vehicle distribution coefficient (C) on the Manual of Indonesian Flexible Pavement Design (SKBI-2.3.26.1987). This paper discusses the effect of city characteristics, lane configuration, and flow level on vehicle distribution in urban road lanes. Three cities were observed, i.e. Mataram, Bandung, and Surabaya. Ten road links were observedwhich consist of six 4 lanes-2 ways and four 6 lanes-2 ways divided roads. Surveys were carried out for 24 hours of a normal working day. Traffic counts were grouped every 15 minutes per direction, per lane for 3 vehicle types. i.e. light vehicle, heavy vehicle, and motorcycle. T-test of mean differences was used as a technique for analysis. The results show that the design lane was the most right lane and the values of C in Mataram, Bandung, and Surabaya were higher than those on the Manual

Tingkat Ketaatan Pengemudi Sepeda Motor Dalam Penggunaan Lajur Jalan Pada Berbagai Kondisi Arus Lalulintas

A rapid increase of motorcycle ownership in the last twenty years made a decline to the road safety. This condition led Jakarta government to announce a policy for motorcycles to ride on leftmost lane on the road effectively by January 2007. Therefore, this paper analyzes the obedient of motorcyclist to the policy after about 4 months officially announced in various traffic conditions. This paper analysis is based on the 24 hours observation on both directions of Letjen. S. Parman Arterial Road using video recorder. First of all the distribution of motorcycles across the lanes are analyzed. Furthermore, the percentages of motorcycle in the leftmost lane on different time periods and different V/Cs are compared using t-test. Additionally a Pearson correlation analysis is also conducted between the percentage of motorcycle in the leftmost lane and several other variables. The results shows about 46 percent of motorcyclists obey the policy. The analysis also shows that there are significant differences between the obedience of motorcyclists in the 10.00-16.00 observation periods and in the 22.00-06.00 observation period

CURATION AND MANAGEMENT OF CULTURAL HERITAGE THROUGH LIBRARIES

Libraries, museums and archives hold valuable collections in a variety of media, presenting a vast body of knowledge rooted in the history of human civilisation. These form the repository of the wisdom of great works by thinkers of past and the present. The holdings of these institutions are priceless heritage of the mankind as they preserve documents, ideas, and the oral and written records. To value the cultural heritage and to care for it as a treasure bequeathed to us by our ancestors is the major responsibility of libraries. The past records constitute a natural resource and are indispensable to the present generation as well as to the generations to come. Libraries preserve the documentary heritage resources for which they are primarily responsible. Any loss of such materials is simply irreplaceable. Therefore, preserving this intellectual, cultural heritage becomes not only the academic commitment but also the moral responsibility of the librarians/information scientists, who are in charge of these repositories. The high quality of the papers and the discussion represent the thinking and experience of experts in their particular fields. The contributed papers also relate to the methodology used in libraries in Asia to provide access to manuscripts and cultural heritage. The volume discusses best practices in Knowledge preservation and how to collaborate and preserve the culture. The book also deals with manuscript and archives issues in the digital era. The approach of this book is concise, comprehensively, covering all major aspects of preservation and conservation through libraries. The readership of the book is not just limited to library and information science professionals, but also for those involved in conservation, preservation, restoration or other related disciplines. The book will be useful for librarians, archivists and conservators. We thank the Sunan Kalijaga University, Special Libraries Association- Asian Chapter for their trust and their constant support, all the contributors for their submissions, the members of the Local and International Committee for their reviewing effort for making this publication possible

Drying colloidal systems: laboratory models for a wide range of applications

The drying of complex fluids provides a powerful insight into phenomena that take place on time and length scales not normally accessible. An important feature of complex fluids, colloidal dispersions and polymer solutions is their high sensitivity to weak external actions. Thus, the drying of complex fluids involves a large number of physical and chemical processes. The scope of this review is the capacity to tune such systems to reproduce and explore specific properties in a physics laboratory. A wide variety of systems are presented, ranging from functional coatings, food science, cosmetology, medical diagnostics and forensics to geophysics and art

A Voltage Rise Mitigation Control Scheme of Utility-Scale Battery in High PV Penetration

In the distribution grids with high R/X proportion, active power curtailment (APC) of battery energy storage system (BESS) becomes an effective strategy for mitigating voltage rise, which is caused by high photovoltaic (PV) penetration. To this purpose, previous researches have presented studies of utilityscale BESS implementation for utility-scale PV penetration. However, the requests for customer-scale PV integration into distribution grids are rapidly increasing. This condition leads to the requirements for studying the performance of utilityscale BESS for the customer-scale PV penetration. Therefore, this article proposes a voltage rise mitigation control scheme of utility-scale BESS for high penetration of customer-scale PV systems. Since the previous studies provided the BESS implementation for utility-scale PV penetration, implementing the BESS control scheme on the distribution system with high customer-scale PV penetration is necessary. It is because, in the last few years, the PV penetration is increasing massively. Moreover, to perform an appropriate BESS control, a control scheme based on the maximum voltage is proposed in this research. To justify the proposed method, the IEEE 123-node test feeder is employed. The results indicate that the proposed control scheme can be used by the distribution system operator in utilizing the utility-scale BESS for voltage rise mitigation in the system with high penetration of customer-scale PV systems. Specifically, this article provides the foundation for performing future studies. © 2021 IEEE
