Abstract

A construction project has several factors that affect the success of a project. One of the factors was an optimal project’s cash flow. Optimizing cash flow of a construction project can be done by making several cash flow plans, and choosing the best one considering appropriate project’s time and cost constraints. The purpose of this study is to obtain an optimal cash flow plan on a construction project using a capital loan from Sharia Bank. This research will be carried out on a specific project which is Construction and Rehabilitation Project of Government Health Service Building, District of Gunungkidul. In this study, the method used to analyze data is to make several project cash flow based on “Earliest Start” scheme by determining the duration for each activity and creating a network diagram using the Precedence Diagram Method (PDM). The final step is analysing the cash flow by calculating negative overdraft for each cash flow plan to determine the amount of capital loan from Sharia Bank and then comparing profits to obtain the optimal one. Analysis and discussion reveal that on the system of given Down Payment, and Project’s Termyn 50%, 75% and 100%, and a loan from Sharia Bank it is found that the optimum cash flow will make profit of 7.49%. Keywords: Cash Flow, Earliest Start (ES), Optimal Profit, Sharia Bank.

Abstract

The permit process must comply with laws and regulations. The permit functions as controlling and supervising tool from the government of activities in certain cases based on the guidelines that must be implemented. The permit also functions as a disciplinarian and regulator in accordance with the law in the administration of government. In the process, several constrains or obstacles often occur in terms of the period of the process as well as technical and non-technical constrains. In this research, an analysis of the scheduling of the site plan permit approval process is based on field data related to the site plan permit approval process with the PERT method. The data used are primary data in the form of interviews and filling in the form of questions and secondary data in the form of a site plan approval process flow. The data that has been collected is then processed and analyzed in several stages. First, calculate the expected time period (te) using interview data and the results of filling in the expected time period (te), so that the expected time period for each activity will be found in accordance with the site plan approval process flow. Second, determine the dependency relationship between activities. In this stage, the relationship between each activity is determined. Third, create a network by changing the existing site authorization process flow into a form of network planning. The results of the schedule using the PERT method are a period of 38 days with alternatives that can be done to reach the time (Tx) of 18 working days in accordance with the Regent Regulations. In addition, the probability of the overall activity being completed is 0.8531 or 85.31%.

Abstract

Construction projects are activities that are prone to work accidents, so work safety management is needed to prevent work accidents. One of the factors that greatly influences the perception of work safety is the job security. The aim of this research is to identify job security factors and safety perceptions and analyze the influence of the relationship between job security and the perception of safety among field workers in the oil and gas industry, especially in the Riau province work area. The respondents were field workers and numbered 106 people. The research methods used are qualitative and quantitative. There were respondents who stated that the implementation of work safety was very high, but several dimensions such as sustainable salary increases were still not good (34.91%) and respondents stated that understanding and implementation of the perception of safety was very high. The results of the linear regression test show that job security has a positive and significant effect on the perception of safety among field construction workers, where job security contributes to the perception of safety by 21.5%. The more workers do not fulfill job security, the less workers will care about the perception of safety which can lead to not creating a good safety climate and increasing work accidents

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

Kabupaten Batang, yang terletak strategis di sepanjang Jalur Pantura, saat ini sedang melaksanakan pembangunan infrastruktur untuk meningkatkan aksesibilitas transportasi barang dan bahan baku antara pelabuhan dan kawasan industri. Salah satu proyek penting yang sedang berlangsung adalah Pembangunan Akses Jalan Jetty Kawasan Industri Terpadu (KIT) Batang, yang termasuk dalam Proyek Strategis Nasional. Salah satu elemen kunci dalam proyek ini adalah pekerjaan half slab, yang menggunakan sistem pelat beton pracetak dan pengecoran konvensional. Penelitian ini bertujuan untuk mengoptimalkan waktu dan biaya pelaksanaan pekerjaan half slab dengan melakukan redesign menggunakan metode Building Information Modeling (BIM) 3D, 4D, dan 5D. BIM 3D digunakan untuk visualisasi desain, BIM 4D untuk simulasi jadwal, dan BIM 5D untuk perhitungan kuantitas material serta biaya. Dalam studi ini, terdapat empat tipe half slab yang digunakan, dan melalui analisis teknis, ditemukan bahwa redesign half slab dapat mempercepat waktu pemasangan di beberapa area proyek. Di area EJ5 – EJ4, waktu pengerjaan dapat dipersingkat 9 hari, sementara di area EJ4 – EJ3 dan EJ3 – EJ2, dapat dipersingkat masing-masing 1 hari. Dari segi biaya, hasil analisis menunjukkan bahwa meskipun biaya pengadaan half slab redesign lebih tinggi sebesar Rp. 27.350.749 dibandingkan dengan half slab eksisting, desain ulang ini menghilangkan kebutuhan biaya bekisting sebesar Rp. 23.969.984 dan memangkas biaya beton lantai jembatan sebesar Rp. 513.207.303. Total biaya pemasangan half slab redesign sebesar Rp. 4.221.200.440. Penelitian ini diharapkan dapat memberikan kontribusi signifikan dalam mengoptimalkan waktu dan biaya pada proyek infrastruktur, serta memberikan manfaat jangka panjang bagi efisiensi transportasi di Kabupaten Batang.
