Abstract

Construction infrastructure development in West Kalimantan Province is carried out every year in order to achieve community welfare. One example is building a hostel building. Dormitory is a building that is used to accommodate students from within or outside the area. To fulfill the facilities and amenities for Landak Regency female students, it is necessary to build a dormitory carried out by the Landak Regency Government. Construction management is the right solution in planning a dormitory building. The data collected included primary data in the form of field observations (land area) and field documentation (photos) and secondary data in the form of working drawings, basic prices for 2022 Pontianak City, AHSP based on PUPR Government Regulations 2022 and literature in the form of books and e-books. There are 5 aspects of construction management that will be discussed, namely project cost management, project quality management, project time management, project human resource management (HR) and project occupational safety and health (K3) management. Obtain volume calculations, budget plan (RAB), recapitulation of RAB, work plans and requirements (RKS), S curve, Network Planning using the CPM method, workforce requirements, identification of OHS risks, risk control hierarchy and RK3K costs. The results of the planning have obtained a budget plan of Rp. 10.301.793.000,00, the planned duration of time for work to be completed is 210 calendar days or 7 months based on the S curve, project quality uses general requirements based on planned drawing specification data, human resources get manpower requirements the most workers were 78 people and got the APD and APK requirements and calculated the cost of the contract work safety and health plan (RK3K) of IDR 33. 867.000,00. Keywords: student dormitory, planning, construction management.

Abstract

Concrete is a composite material (mixture) of several materials whose basic binder consists of a combinationof fine aggregate, coarse aggregate, water and different additives in a particular mixture. Sand is a fillermaterial that is used with a binder and water to form a dense and hard mixture. The beach sand in the JawaiDistrict, Sambas Regency has the potential because of its availability in large quantities, namely 42.53 kmlong, quite a lot of sandy beaches and rocks in the hills of Ramayadi Village. This study aims to compare and determine the value of the compressive strength of concrete produced fromconcrete using beach sand as a substitute for fine aggregate that is treated (washed and not washed) and byusing coarse aggregate in the form of crushed stone from the South Jawai District, Sambas Regency. Theresearch was conducted on cube specimens measuring 15 cm long, 15 cm wide and 15 cm high.The tests carried out were testing the compressive strength of concrete at the age of 7 days and 14 days. Thetest results at the age of 7 days for unwashed beach sand and washed beach sand respectively showed anaverage compressive strength of 114.0514 kg/cm2 and 153.9535 kg/cm2. While the test results at the age of14 days for unwashed beach sand and washed beach sand respectively showed an average compressivestrength of 142.6046 kg/cm2 and 209.8392 kg/cm2.These instructions give you guidelines for preparing papers for Jurnal Retensi.
