Abstract

Salah satu upaya yang dilakukan oleh perusahaan jasa konstruksi untuk meminimalkan angka kecelakaan adalah melaksanakan sistem manajemen keselamatan dan kesehatan kerja (SMK3) konstruksi. Penyedia jasa konstruksi harus menyediakan biaya untuk keperluan K3 yang diambil dari total biaya proyek. Penelitian ini memiliki tujuan yaitu agar dapat diketahui besaran biaya keselamatan dan kesehatan kerja yang diperlukan juga perbandingannya antara peraturan dan lapangan. Penelitian dilaksanakan dalam bentuk survey dan wawancara dimana tahapan analisis data adalah menyusun daftar risiko yang terjadi, menilai risiko, mitigasi risiko, melakukan perhitungan biaya K3 dengan harga hasil survey toko dan harga Surat Edaran Nomor 11/SE/M/2019 (SE19) dan menghitung persentase biaya K3 terhadap kontrak. Hasil penelitian menunjukkan teridentifikasi 22 risiko kecelakaan dan keselamatan kerja dengan 14 risiko kategori rendah dan 8 risiko kategori sedang. Biaya K3 yang diperlukan bersadarkan harga satuan lapangan adalah sebesar Rp. 402,142,520.00 sedangkan biaya berdasarkan peraturan SE19 adalah Rp. 359,005,000.00. Biaya K3 harga lapangan lebih besar daripada biaya K3 harga SE19 dengan selisih 0.08% atau sebesar Rp. 43,137,520.00.

Abstract

ABSTRACT The main objectives in the construction project are completed with the appropriate cost, time, quality according to specifications, and the fulfillment of work safety. However, the construction project have a problem. In this study, the project problem that occurs is a change in contract documents. The research was carried out through interviews and brainstorming with parties involved and competent in their fields. From the results of interviews and brainstorming, it was found that the changes that occurred were changes in structure design, addition of work items, reduction of work items, and changes in finishing materials. The cause of this change is the difference in architectural structure and function images by the planning consultant, the owner and consultant planner's desire to add /reduce work items, the desire of the owner and consultant planner to change the finishing material used. The impact of these changes is in the Compensable Delay category. Earned Value analysis is carried out at the end of the work, with the result that the project has an extension of 3 months and there is an addendum of additional work of 6.14% of the contract value. This condition needs attention for the owner and consultant planner to finalize the design/image before the tender process is carried out to reduce the risk of additional project time and costs. Keywords: contract documents, project performance, earned values ABSTRAK Tujuan utama dalam proyek konstruksi adalah terselesaikannya proyek sesuai dengan biaya yang dianggarkan, waktu yang direncanakan, mutu yang sesuai dengan spesifikasi, dan terpenuhinya keselamatan kerja. Namun kenyataannya, proyek konstruksi pasti memiliki kendala-kendala yang menyebabkan terjadinya permasalahan proyek. Pada penelitian ini, permasalahan proyek yang terjadi adalah akibat adanya perubahan dokumen kontrak. Penelitian dilakukan dengan wawancara dan brainstorming dengan pihak yang terlibat dan berkompeten dibidangnya. Dari hasil wawancara dan brainstorming, diperoleh identifikasi perubahan-perubahan yang terjadi yaitu perubahan desain struktur, penambahan item pekerjaan, pengurangan item pekerjaan, dan perubahan material finishing. Penyebab terjadinya perubahan ini adanya perbedaan gambar struktur dan fungsi arsitektur oleh konsultan perencana, keinginan owner dan konsultan perencana untuk menambah/ mengurangi item pekerjaan, keinginan owner dan konsultan perencana untuk merubah finishing material yang digunakan. Dampak dari perubahan-perubahan tersebut masuk dalam kategori Compensable Delay. Analisis Earned Value dilakukan pada akhir pekerjaan, dengan hasil bahwa proyek mengalami perpanjangan waktu 3 bulan dan terjadi addendum penambahan pekerjaan sebesar 6.14% dari nilai kontrak. Kondisi ini perlu mendapat perhatian bagi owner dan konsultan perencana agar mematangkan desain/ gambar sebelum dilakukan proses tender untuk mengurangi risiko penambahan waktu dan biaya proyek. Kata kunci: dokumen kontrak, kinerja proyek, earned value

Abstract

Project cost control is important in the project management process to avoid losses. Project control can be carried out in terms of cost and time. One way to control project costs is to choose the design, materials to be used in the project, and the implementation methods to be used. The objective of this study is to obtain an alternative structural design with an optimal construction cost of structural work by considering the use of concrete quality in reinforced concrete structures, column spacing and cross-sectional dimensions of structural elements. The existing design is to use quality K250 concrete. In this study the cost analysis of the concrete structure, foundation, tie beam, beam, column and ring beam work results from value engineering. The stages of research start from the design information stage, the creative stage that is determining the design alternatives and the analysis stage. The analysis was carried out by structural analysis using SAP2000 and analysis of concrete work costs. The results of the analysis of alternative designs namely reducing the dimensions of the cross-section, using K300 quality concrete, eliminating structural elements that do not need to meet in the calculation of the structure. The next step is to calculate the cost of the concrete work. Concrete structure work when using an alternative design that is to reduce the dimensions of the structure, change the quality to K300 and eliminate unnecessary elements that can save costs by IDR.35,956,756.00 or 37.02%.

Abstract

One of the problems in construction activities is the risk of delays in the construction project. In The Himana Condotel project, several obstacles make some of the work not on the schedule. We analyze risk factors for delays to find out the dominan risk dan the solution. This research method uses a quantitative descriptive method and using questionnaires and interviews. The respondents were taken based on the criteria that are the respondent who has the important position at the Himana Condotel Project. From the data, we can specify the frequency and consequences occur risk that uses semantic differential scale in the questionnaire, that obtained the dominant risk factor based on the risk rating table with the highest risk level. After we get the dominant risk factors and the risk description, then we can determine the mitigation action that we can suggest. From the analysis, we get 5 variable risk factors for delay from The Himana Condotel project that is planning aspects, employment documents and contracts aspects, implementation aspects, resource aspects, and environmental aspects. Of the five aspects, the risk descriptions are described as 48. The dominant risk is obtained based on the percentage of the risk level, the risk level is obtained with a value of 36 %. From the five aspects of the risk factors for delays, all of them have high risks and 17 descriptions of risks that have a high-risk level. The suggested matters for the dominant risk mitigation to be carried out are more coordination between the parties involved, the preparation of schedule and planning in more detail, technical implementation in the fields especially for BQ, contract, work planning and terms to get more attention and increase the accuracy of the implementation of work as planned.

Abstract

Project risks sourced from the environment, planning, financial, technical, humane, criminal, and safety. The purpose of this study to identify the safety and health risks of building construction on structural and architectural work, determine the value of risk based on the results of identification, determine risk control based on the hierarchy of risk control. This research was conducted on a private construction project on structural and architectural work. The method used is interviews and surveys. Surveys were conducted to obtain risk identification, and interviews to respondents. There were 28 identified risks, 11 risks were in the mild category and 17 were moderate risks. This risks are controlled by tool box meetings, managing work positions, placement of materials and tools, installing signs, work permits, using helmets, shoes, safety belts, gloves, and masks.
