Abstract

THE IMPLEMENTATION OF VALUE ENGINEERING ON SCHOOL BUILDING CONSTRUCTION PROJECT(CASE OF STUDY SANUR INDEPENDENT SCHOOL)ABSTRACTIn a construction project, the cost is one of the factors that determine the sustainability of the project, especially in the case of study school building project at Sanur Independent School. Because of that, the austerity measures undertaken to produce an economical construction project. The selection of materials and construction methods can precisely determine the amount of savings to be gained in the implementation of the construction project, wherein the choice of materials and alternative methods will not necessarily reduce nor change the value of the function, quality and architectural value of the project itself. Therefore there is a need for job costing analysis to control these aspects. One of the methods that used for cost efficiency in a construction project especially on the building construction is Value Engineering Method that is a systematic way of defining the value of a subject to its function so that an innovative and structured approach can be adopted with the aim of reducing unnecessary costs. By using this method can obtained two alternative combinations of designs such as , the best combination of alternative designs and the cheapest combination of alternative design, and based by the result of the researched, by using a combination of the best alternative design on this construction project wherein the initial BoQ have a value of Rp 2,003,372,657.68 obtained savings of Rp 36.492.428,34 atau 1,82 %. While using a combination of the cheapest alternative designs obtained savings of Rp 248,161,362.38 or 12.39 %.

DUCTILITY OF DOUBLE NOTCH CONNECTION IN PRECAST BEAM COLUMN JOINT, DUE TO CYCLIC LATERAL LOADSABSTRACTBy considering the structure of precast concrete as a monolithic structure, flexural and shear reinforcement of beam column joint can be planned based on the design capacity This research is an experimental study in a full-scale laboratory, which aims to analyze the precast ductility value of double notch models due to cyclic lateral loads. The specimen consists of two models, which are precast beam-column connections and monolithic beam column. The precast and monolithic specimen were designed for the same strength. The cross-sectional dimensions of the beam 250 mm x 300 mm and column 300 mm x 300 mm. This research was carried out with the following stages : (1). Physical Test of Concrete Materials (2). Physical Test of Reinforced Steel Material (3). Strength bonding test (4). Physical test of precast column beam connection. Tests are carried out after the concrete is more than 28 days old. The results showed that after being given a cyclic load on the two structural models, connection precast beam-column joint type of double notch (STRS) type were better able to deform under tensile loads (ductility = 5.52), while the monolith column beam components were better able to deform compressive load (ductility = 7.66). Based on the ductility value obtained, the connection of this double notch model can function as a full ductile connection, so that it can be applied to the building of earthquake force retaining structures for special moment bearers

Abstract

LABORATORY SCALE MODELING OF GROUNDWATER CONTAMINATION BY WASTE USING GEOELECTRIC METHODABSTRACT Research has been carried out with physical modeling using the geoelectric method to monitor the problem of water resources namely water pollution by waste. Pollution caused by industrial waste is a big problem, if the waste seeps into the soil and contaminates ground water consumed by humans, animals and other organisms. Decreasing groundwater quality can affect the fulfillment of community needs for clean water. Because the impact of industrial wastewater can not be directly felt, making people less aware of the dangers of waste that can pollute the presence of ground water. The purpose of this study was to identify the spread of liquid waste using the 2D type geoelectric method and find out the resistivity value. The tools used are type G-Sound Resistivity meter (GL-4100) and used liquid waste material used oil. Data processing was processed using RES2Dinv ver 3.3 software and obtained medium type resistivity values contaminated by liquid waste from geoelectric data of resistivity type was 0.962 - 12.4 ?m and from the geoelectric cross section (pseudosection) visible boundaries or areas contaminated with liquid waste contained in depth of 0 - 0.44 m from ground level (ground surface). On the results of data processing, there is a high value of species resistance, 44.5 - 84.3 m, which is interpreted as iron sand found in the clay sand medium used.
