South Sumatra is one of the provinces whose development is very rapid in Indonesia. With the increasing development of centers of economic activity, politics, socio-culture and education make it an attraction for residents outside the city to travel to Palembang City. However, the condition of the eksisting highway which has become the driver's mainstay for travelling are not free of congestion. This causes travel time and Vehicle operational costs increase for every vehicle that passes the road. To overcome this problem, the government brought investors to build a toll road. The results of preliminary research show that people are still confused about the benefits through toll roads which are built besides travel time faster because they have to spend money to pay tolls. The main objective of this study was to determine the vehicle operating costs (VOC) using both roads with the Pacific Consultant International Method (PCI) and Industrial and Affiliate Research, Bandung Institute of Technology (LAPI ITB). Variable of the equation to determine the cost components is travel speed determined the Floating Car Method. The results show that the operational costs of vehicles (VOC) through toll roads are smaller when compared with existing roads. VOC of passenger cars that pass through the existing road in the morning Rp. 3395.45, trucks 2 axles loaded Rp. 5570.55 and trucks 2 axles with no payload of Rp. 3815.00, while if through toll road, passenger cars Rp. 2618.82 and trucks 2 axles Rp. 2918.71. In addition, information is obtained, more than 90% of drivers only consider fuel costs, they do not consider the cost of other variable variables in choosing a route.

The development of the economic sector is determined by services to the public through reforms that aim to place public satisfaction through the management of road infrastructure assets. Some research on road infrastructure assets still requires a deepening of studies related to the delivery of public services related to asset management systems. The purpose of this study is to find an appropriate road infrastructure asset management strategy through an integrated asset management system and asset management policies that can provide public satisfaction. This comprehensive approach to management strategies ensures that the performance of service provider assets is in line with the expectations of stakeholders including road users. This descriptive qualitative research is based on the perspective of road users as respondents, consisting of vehicle drivers from 50 transportation companies (people or goods) through interviews and observations. The results show aspects of asset performance based on the user's perspective there are five aspects, namely productivity, efficiency, effectiveness, use of resources and institutions and this performance is integrated in the asset management system related to policies from the management authority through service delivery namely quality and mobility, risk and use and maintenance of resources. The conclusion of this research is that road infrastructure asset services can be improved through the concept of road infrastructure asset management strategies in an integrated management system with five aspects of performance and more directed towards asset management policies related to the provision of road infrastructure asset services.

引用

IOP Conference Series: Earth and Environmental Science 2020年第1期575卷

作者： Untari R Darma P Betaubun A A Arief PhD. Student on Agricultural System Graduate School Hasanuddin University South Sulawesi Indonesia Department of Agribusiness Faculty of Agriculture Universitas Musamus Papua Indonesia Agribusiness Study Program Faculty of Agriculture Hasanuddin University South Sulawesi Indonesia Department of civil Engineering Faculty of Engineering Universitas Musamus Papua Indonesia Socio Economic of Fisheries Study Program Faculty of Marine Science and Fisheries Hasanuddin University South Sulawesi Indonesia

Mangrove forests have an important function in human life that cannot be replaced by other functions. The existence of mangrove forests has six main functions, namely biological, ecological, physical, social, economic and chemical functions. This article discusses the description of mangrove forest management in meeting the needs of the economic and social functions of the fishing communities on the coast of Merauke Regency, Papua Province, which were reviewed descriptively using relevant literature studies. In terms of economic function, mangrove forests provide economic value for fishing communities because mangrove forests become habitat for crabs, fish and other marine biota that are captured and sold as the main source of family income. In addition, the use of mangrove forests by fishermen on the coast is used as firewood and building materials. The high utilization of mangrove forests by coastal communities that ignores ecological sustainability causes damage to mangrove forests that threatens the sustainability of ecological functions. Damage to mangrove forests in Merauke in the period 2000-2005 was recorded as wide as 2,416 ha while in the 2005-2010 period damage reached 2,233 ha of the total area of the Merauke mangrove forest which reached 216,001.95 Ha or 6.98% of the Merauke forest area. Based on this, the management of mangrove forest utilization needs to get more attention from various parties so that the ecological function of mangrove forests as a condition of sustainable development, especially for fishing communities on the coast, can be realized in Merauke Regency.

作者： Asep Sundara Risna Rismiana Sari Tanya Audia Balqis Civil Engineering Department Politeknik Negeri Bandung Bandung Indonesia Post-Graduate Student of Infrastructure Engineering Study Program Applied Master Program Politeknik Negeri Bandung Bandung Indonesia

Modifying asphalt concrete with using Crumb Rubber (CR) can provide environmental benefits. The method used in this study is an experimental laboratory with Mashall machine. The tests used two types of gradation, namely the gradations of Ideal and Laboratory Test. CR used in a mixture with a dry process method to replacement 0%, 5%, 15% and 20% of the weight aggregate at fraction No. 30 (0.6 mm). The results showed that the Ideal gradation mixture has a better characteristic than the mixture of laboratory tested gradations. Ideal gradations can increased stability into 10% from Laboratory Test gradations for mixture without CR. Addition of CR contect in AC mixture did not significantly effect for the characteristics. To ensure the effect of CR in mixture, further test must be taken.

The Effect of EPS Addition to Soil Stabilized with Fly Ash as Lightweight Fill Materials for Embankment Construction

引用

Journal of Physics: Conference Series 2019年第1期1364卷

作者： Syahril Andri Krisnandi Somantri Aditia Febriansya Civil Engineering Department Politeknik Negeri Bandung Bandung Indonesia Civil Engineering Department Politeknik Negeri Bandun Bandung Indonesia Post-Graduate Student of Infrastructure Engineering Study Program Applied Master Program Politeknik Negeri Bandung Bandung Indonesia

Design and construction of road embankment presents several challenges, including the possibility of bearing capacity failure, large total settlement, differential settlement, and slope instability, which may result from the weight of the embankment construction itself, and/or weak foundation. A number of techniques have been developed and can be used to overcome these problems, one of them is by modifying the weight of the embankment itself with the use of lightweight materials, such as soil-EPS mixture. The use of soil-EPS mixture as lightweight material provides several advantages, among which can achieve the same volume or elevation requirement with a significantly lighter weight compared to ordinary materials, improving slope stability, embankment over high compressibility soil, and to reduce soil pressure to soil retaining structures, abutment or bridge pillar. Fly ash also added to act as binder to increase shear strength of mixture. The result of the compaction test shows that the addition of a small amount of EPS to the mixture can significantly reduce the maximum dry density of the mixture. Triaxial UU and UCS test results show a reduction in mixture strength as EPS contents increase, but due to the presence of fly ash increases the strength of mixture as the number of day increases, so that the use of lightweight materials has the potential to be one of soil improvement solutions.
