Analisis Perencanaan Tebal Lapis Tambah (overlay) Cara Lenduntan Balik Dengan Metode Pd T-05-2005-B dan Pedoman Interim No.002/P/BM/2011

Roads are the transport infrastructures which play an important role in supporting the economicgrowth of a region. Therefore it is necessary to do maintenance efforts so that the roads canfunction optimally.One of them is by adding overlay. The selection of methods become a factorthat must be considered before doing flexible pavement overlay design. It is because of improperplanning can cause damaged or uneconomical construction of roads. Along with the technologicaladvances, methods of overlay flexible pavement design based on deflection also undergone manymodifications such as“Pedoman Perencanaan Tebal Lapis Tambah Perkerasan Lentur Pd T-05-2005-B”and “Pedoman Interim Perkerasan Jalan Lentur No.002/P/BM/201”. The purpose of thisresearch was to determine the most optimal and most efficient life cyclecost of overlay design inthe roads performance improvement project of Batas Kota Metro-Gedung Dalam. From theanalysis results show that the design results by using Pd T 05-2005-B were thinner than PedomanInterim No.002/P/BM/2011. It was caused by several factors such as the analysis of traffic,temperature correction factor, and the types of materials used. The indicator value of theinternational roughness index (IRI) is predicated by emperical equations and the design life of 20years, obtained the lowest lifecycle costs are the result of design methods Pd T-05-2005-B. Theresults of the analysis also showed that the cost at the end of the design life methods Pd T-05-2005-B less than Pedoman Interim No.002 /P/BM / 2011.Keywords :Road, Overlay, Life Cycle Cos

Redesign Metering and Regulating Station Pada Sistem Jaringan Gas Rumah Tangga Sidoarjo

Abstract - PT PGAS Solution is a company engaged in the transmission and distribution of natural gas that requires distribution facilities in the form of gas pipes as a gas distribution. The Metering Regulating Station is the equipment for custody, safety and pressure regulation at each distribution point. For every house connection that will subscribe to natural gas, a calculation and analysis of the design of the natural gas pipeline and the Metering Regulating Station will be carried out according to the pressure, flow and estimated usage requirements for 1 month as in the Sidoarjo gas line, which originally amounted to 17,543 house connections, has now increased to 28,961 house connections. . The estimation of gas usage in daily distribution is 2896.1 m3 of natural gas per hour, so it is necessary to calculate the diameter of the pipe, turbine meter and identify the appropriate Metering Regulating Station to distribute gas from the distribution network to the existing pipeline. After calculating according to the needs in Sidoarjo, the identification of the most suitable MRS is (6/6)-(40/10) -(4/1)–(2000)–(G.400) which describes the MRS inlet outlet diameter, pressure maximum and minimum, maximum flow and type of meter used. The pressure drop value based on the simulation using the Pipe Flow Expert software in this design is 0.0125 bar where this number is still in accordance with the basic design criteria of PGAS Solution
