Abstract

Planning the Structure of the Semarang Hajj Dormitory Building is located on Jl. Abdul Rahman Saleh No. 285, Kalipancur, Kec. Ngaliyan, Semarang City, Central Java. This arama was built to improve the facilities and infrastructure of pilgrims in the Semarang area.The planning of this building is carried out with primary data such as data from soil sondir, and is equipped with other secondary data. This structural planning analysis is assisted by the SAP 2000 software application (Structure Analyst Program) for structural modeling and calculating internal forces. The analysis carried out includes: calculation of the structure of the Foundation, Columns, Beams, Plates and Roofs.From the results of the analysis obtained the type of foundation using piles with P1:1.00x1.75x0.70 m with 2 piles measuring 30x30 cm 9 m depth, P2:1.80x1.80x0.70 m with 4 piles measuring 35x35 cm depth 9 m, P3:1,90x1,90x0,70 m with 5 piles measuring 30x30 cm with a depth of 9 m. beam size 40x70 3-D22 principal reinforcement (support) 10-150 shear reinforcement, 3-D22 principal reinforcement (field) 10-150 shear reinforcement. beam size 30x50 2-D22 principal reinforcement (support) 10-150 shear reinforcement, 2-D22 main reinforcement (field) 10-150 shear reinforcement. beam size 15x30 main reinforcement 2-D19 (support) shear reinforcement 10-150, 2-D19 main reinforcement (field) shear reinforcement 10-150. Column 60x60 main reinforcement 8-D25, shear reinforcement 10-150. Column 70x70 main reinforcement 12-D25, shear reinforcement 10-150. Roof rafter beam WF 250.125.6.9, steel column WF 250.125.6.9, gording C. 125.50.20.2,3, roof covering: steel roof (span deck) distance between roof rafter beams 4 m, distance between steel columns 4 m, distance between gording 1 m, bolt diameter using 16 mm and steel anchor diameter 16 mm (length 50 cm). From the calculation results, each element of the building structure can be categorized as safe.

Abstract

Paving block is an environmentally friendly construction where paving blocks are very good at helping groundwater conservation, implementation is faster, easy to install and maintain, has a variety of forms that add aesthetic value, and the price is easy to reach. Therefore, paving blocks are an important building material in the construction of public facilities, especially for road construction in residential areas. The use of paving blocks in the field is still limited to parking lot pavements, sidewalks, parks and connecting buildings. Even though the application of paving block materials is very wide. However, of course, local experience and the successful use of paving blocks will play more and more influence in terms of the application of these materials. Stone ash in this study was used as a substitute for natural fine aggregate (natural sand) with the proportions of 0%, 15%, 30%, 45%, and 60%. To get the optimal compressive strength value, the researcher has the opinion of a combination of fine aggregate of natural sand and rock ash waste with the appropriate percentage. And tested with mortar age of 14 days and 28 days. In the study, the volume weight test of paving blocks with the addition of stone ash waste obtained the highest compressive strength at a variation of 45% for the test at the age of 14 days and 28 days, with the compression test for 14 days reaching a compressive strength of 100.92 kg/cm2 and for the compressive test 28 day reached a compressive strength of 160.28 kg/cm2.

Abstract

The Construction Project for the Public Service Office Building for the Highways and Human Settlements Office of Central Java Province is carried out from February to October 2021, with total contract value of Rp. 8,313,888,968. This project using planning and controlling time and costs so that later work will be more efficient, according to plans and objectives. The purpose of this study is to determine the time performance of the Development Project, to find out the problems encountered in the implementation of the Project, as well as the solutions used to overcome the problems that arise. The method used in this study is the Earned Value Concept method in which it combines elements of schedule, cost, and work performance to calculate the estimated cost and time needed to complete the project to completion. The data obtained from the Project includes the Budget Plan (RAB), Project Work Schedule, Daily, Weekly, Monthly Reports and actual cost requirements. Furthermore, an analysis of costs, schedules, and work performance is carried out by explaining the problems that arise during the research. From the results of the research and analysis it is known that the total costs incurred are relatively the same as the budget that has been planned, this is indicated by the results of CV = 1 and the project implementation time has been delayed from the planned schedule, indicated by the results of SPI = 6.6883 The results of calculating an estimated cost of Rp. 8,313,888,968 with an estimated completion time of 36 weeks which indicates a delay of 1 week from the planned 35 weeks. Where this delay was caused by several factors such as weather conditions which were in the rainy season when the project was running, damage or inadequate tools.
