Abstract

For construction of million houses needed by Indonesians, material efficiency should be prioritized. This is because so many wasted materials in the process. For example, much mortar is wested on a masonry work. To minimize the waste, a mortar mold should be used. The objective of this study was to determine the efficiency that could be got by using a mortar mold in a masonry work. The reseach method was experiments. The result was determined by comparing the mortar needs between the two ways, i.e. with and without the masonry mold tool. Twenty-one experiments have been conducted for each way. The results of this study indicate that using of the tool could save about 23% of mortar or 23% of the material cost.

Abstract

Cost estimate is very important for all parties involved in a construction, such as owners, contractors, consultants, investors. A method for calculation of cost estimate is Budget Plan (RAB). However, the calculation requires some competencies and time. The objective of this study is to develop a easier method to calculate the cost estimation, i.e. by developing formulations of RAB based on the price of some materials. This research was carried out on simple house projects, which was built in 2014 in regions of Magelang, Bantul, Sleman and Yogyakarta. The data were collected by observation and interviews in the fields. The interviews were conducted to collect information of material prices and labor costs used as the independent variables. While, the observation aimed to calculate the value of RAB used as the dependent variable. Analysis of data used the correlation and regression techniques. Based on the analysis, the variables with strong correlation with RAB is prices of the brick (0.907), while the correlation between employee wage and RAB is quite low. The regression analysis resulted that the cost of house construction can be predicted by equations: RAB = 66,823 X1 - 1.277.771 or RAB = 53,244 X1+ 26,423 X2 -1.826.152, with X1 is the price of standard brick per hundred pieces expressed in rupiah and X2 is a prices of floor covering material per square meter  stated in rupiah. Based on the validation, the accuracy of the formulations is over 97%. Estimasi biaya memiliki fungsi yang sangat penting dalam dunia konstruksi bagi semua pihak yang terlibat di dalam konstruksi seperti owner dan investor. Salah satu cara membuat estimasi harga tersebut adalah dengan menggunakan Rencana Anggaran Biaya (RAB).   Bagaimanapun, cara perhitungan tersebut memerlukan kompetensi, ketelitian dan membutuhkan waktu yang cukup lama. Penelitian ini bertujuan mencari cara yang lebih mudah dan cepat untuk menghitung estimasi biaya, yaitu dengan mencari formulasi yang bisa digunakan untuk menghitung nilai RAB dengan variabel bebas harga bahan dan upah tenaga kerja. Penelitian ini dilakukan pada proyek-proyek rumah sederhana tipe 45, yang dibangun pada tahun 2014 di komplek perumahan yang ada di Kabupaten Magelang, Kabupaten Bantul, Kabupaten Sleman dan kota Yogyakarta. Pengumpulan data dilakukan dengan cara observasi dan wawancara langsung di lapangan. Wawancara dilakukan untuk mendapatkkan informasi harga bahan dan upah tenaga kerja yang digunakan sebagai variabel bebas. Sedangkan observasi dilakukan untuk menghitung nilai RAB yang digunakan sebagai variabel terikat. Analisis data penelitian menggunakan teknik korelasi dan regresi. Dari hasil analisis korelasi dan regresi, variabel yang memiliki hubungan paling tinggi dengan nilai rencana anggaran biaya bata merah dengan nilai koefisien korelasi 0,907 yang berarti variabel bebas tersebut memiliki korelasi yang sangat kuat terhadap variabel terikat. Sementara itu korelasi upah tenaga kerja dan RAB cukup rendah. Dari hasil analisis regresi untuk semua variabel bebas didapat persamaan yang dapat digunakan untuk menghitung nilai RAB yaitu, RAB = 66,823 X1 - 1.277.771 atau RAB = 53,244 X1+ 26,423 X2 -1.826.152, dengan X1  adalah harga batu bata ukuran 22 x 11 x 5,5 per seratus buah yang dinyatakan dalam rupiah dan X2 adalah harga material penutup lantai per meter persegi yang dinyatakan dalam rupiah. Formulasi tersebut memberikan tingkat akurasi yang cukup baik, yaitu diatas 97 %.

Abstract

The Kediri Airport development project encountered challenges related to underground ducting work. The design of Kediri Airport adheres to international standards, which led to the use of materials not readily available in Indonesia, specifically pipes and duct spacers. Duct spacers are tools used to arrange ducting pipes according to their formation and prevent them from floating during concrete pouring due to buoyancy. The SKEP/114/VI/2002 serves as a reference for underground cable installation, involving direct burial of cables at a depth of 70 cm, covered with a 5 cm layer of sand above the cable surface. These two approaches significantly differ, necessitating problem-solving solutions. To address this issue, research was conducted to find suitable duct spacers in Indonesia. Two alternative materials were considered: PVC and lightweight hollow steel. The study compared costs and time associated with these materials. PVC duct spacers would be imported and be fabricated in Indonesia, while hollow steel duct spacers would be fabricated on-site. The research focused on three aspects: ducting work methods, duct spacer design, and cost-time analysis. Given tight installation spaces and busy schedules, duct spacers needed to be compact, simple, and adaptable to various pipe formations. The design for hollow steel duct spacers aimed for simplicity to reduce on-site construction work. However, care was taken to avoid potential injuries from exposed bolts on the hollow steel frame. The PVC duct spacer design utilized Polytam PF 1000 material, with a nominal shear strength of 399 kg and a nominal moment of 266 kg·cm—sufficient to withstand saturated soil loads up to 162 cm but not vehicular loads. Analyzing procurement time, PVC duct spacers from Indonesian manufacturers were the quickest, taking only 56 days due to no port clearance delays. The fastest completion time for the project was achieved using PVC duct spacers, taking 122 seconds—three times faster than hollow steel duct spacers. While lightweight steel was the most cost-effective option for on-site procurement, combining cost and time analysis favored PVC duct spacers. The minimal cost difference allowed for accelerated production, minimizing the risk of delays

Abstract

The Bocimi Toll construction project in the Bogor - Sukabumi area is one of the national strategic projects initiated by the government, according to (Indonesiabaik.id, 2017) this project costs an investment of Rp. 7.77 trillion. With these conditions, the need for aggregate material should be large and this quarry business is attractive to run, but in the process the quarry built by PT. TS experienced operational closures, therefore the author wants to evaluate and conduct an analysis related to the investment made.This analyzes using the formula (Net Present Value), (Internal Rate Of Return) and (Payback Period) and identifies the risks that will occur in a quarry construction so that it can be a decision maker when a construction project or someone will open a quarry. In the research conducted, the total investment value was obtained of Rp. 2,300,000,000 and this business process is planned to run for 5 years, the NPV value was obtained with an Interest value of 10.94% positive Rp.34,848,413,722, the IRR value of 51% is greater than the MARR value determined at 15% and the Payback Period value of 0.7 years this business is considered feasible, then conducting a literacy study and interviews obtained 26 variables, there are 9 variables classified as medium risk and 17 high risk variables, Risk response based on probability and impact values ​​there are owners who have 4 variables with the status of risk avoidance, 3 transfer variables and 1 risk reduction variable. The implementer has 3 risk avoidance variables, 6 risk transfer variables and 1 risk reduction variable. The community has 3 risk avoidance variables.Consumers/project owners have 3 risk avoidance, 1 risk transfer and 1 risk reduction. After the variables from the risk analysis are known, they are re-sorted where the risk factors that can increase the cost burden in investment are then analyzed and the costs incurred are known to be Rp. 1,004,222,260 of that value adds to the capital value, then the NPV value is obtained of Rp. 30,127,078,830 has a positive value, the IRR value is known to be 49% is said to be feasible because it exceeds the MARR value, and after calculating the Payback Period value, it is obtained 1.1 years, analytically it can be said that it is still feasible to run. In this study, risk factors that cannot be assessed are also expected to be a reference for ongoing investment considerations, this is to avoid a loss in the construction of the quarry.
