Abstract

Produktivitas merupakan faktor yang dipengaruhi oleh kemampuan performa dalam bersaing di proyek konstruksi. Setiap tenaga kerja menghasilkan produktivitas yang berbeda-beda itu bisa disebabkan beberapa faktor salah satunya yaitu tenaga kerja. Produktivitas yang rendah bisa menyebabkan keterlambatan dalam proses pembangunan proyek dan dapat juga mempengaruhi biaya yang akan dikeluarkan. Metode yang telah terbukti adalah pengamatan langsung dalam kondisi luar ruangan, dengan mengumpulkan informasi dan menghitung produktivitas tenaga kerja. Analisis yang telah terbukti diproses dalam formasi ini dengan metode yang disebut Metode Work Sampling. Waktu pengerjaan suatu proyek konstruksi sangat bergantung pada produktivitas. Semakin rendah produktivitas, semakin besar peluang kerja terlambat. Sebaliknya, semakin tinggi produktivitas, semakin rendah kemungkinan keterlambatan. Di Indonesia, referensi indeks kerja dari manual analisis biaya konstruksi nasional Indonesia umumnya digunakan untuk perencanaan dan pengelolaan pekerjaan dan perencanaan kegiatan proyek konstruksi. Ciri khas pada proyek pembangunan yang diteliti pada penelitian ini ialah Proyek pemasangan dinding bata yang digunakan dalam bahan proyek perumahan Pakuwon City Surabaya yang melibatkan pembangunan pemasangan dinding menggunakan bahan bata. Dalam proyek ini, bata digunakan sebagai bahan dasar untuk membangun struktur dinding. Prosesnya melibatkan pemilihan, pemotongan, dan pemasangan bata sesuai dengan desain yang diinginkan. Proyek dinding bata dapat beragam, mulai dari membangun dinding pembatas, bangunan rumah, tembok dekoratif, dan lain sebagainya, dengan menggunakan bata sebagai bahan utamanya.

Abstract

Pada proyek pembangunan Jalan Lingkar Selatan Kabupaten Sampang dapat dilihat bahwa dalam pelaksanaannya ada keterlambatan proyek yang terjadi. Untuk menemukan penyebab dari keterlambatan, dapat digunakan metode Fault Tree Analysis (FTA). Metode Fault Tree Analysis (FTA) adalah metode yang digunakan untuk menganalisis faktor-faktor penyebab dari suatu kegagalan yang dimulai dengan asumsi kegagalan atau kerugian dari kejadian puncak (top event) kemudian merinci penyebab-penyebab suatu top event sampai pada suatu kegagalan dasar. Tujuan dari penelitian ini adalah faktor yang menjadi penyebab keterlambatan dalam penyelesaian pekerjaan dan mengidentifikasi faktor yang paling berpengaruh dalam menyebabkan keterlambatan tersebut. Hasil ini dapat menjadi acuan untuk proyek berikutnya agar keterlambatan proyek dapat diminimalisir. Berdasarkan diagram Fault Tree dan hasil minimal cut set, terdapat 32 basic event yang menjadi faktor penyebab keterlambatan. Berdasarkan hasil penelitian, diperoleh diperoleh 3 ranking teratas faktor keterlambatan yang paling berpengaruh yaitu keterlambatan penyediaan alat berat dengan nilai mean sebesar 0,79, banyaknya pekerjaan tambahan dengan nilai mean sebesar 0,78, kekurangan peralatan, dan kualitas material yang buruk dengan nilai mean sebesar 0,77.

Abstract

The development of a country's road or toll road infrastructure can be used as a benchmark to judge a country's economic development at both macro and micro levels. The location of toll exits has a significant impact on labor absorption and the creation of new business activities. Projects are dynamic, so contractors must adapt to changing project situations and conditions if they are to succeed in achieving optimal profits. Today's highly competitive aspects of construction planning require high levels of accuracy, efficiency, effectiveness and economy in project analysis. In the world of construction projects, there is much that can be done, including controlling costs. In cost control, efforts can be made so that the realization of costs incurred is consistent with implementation needs and is not excessive, such as efforts to limit costs, that is, to realize savings without does not reduce quantity or quality. The earned value method is used to determine the project's performance in terms of cost at a certain time, determine the project's performance in terms of progress/time at a point in time. certain, estimate the cost to complete the project after the evaluation period and estimate the cost to complete the project after the evaluation period. Project completion time after evaluation. In this study, the author performed a cost analysis using the earned value method for the conservation of Pandaan Malang Section 5 toll road.

Abstract

Kerobokan Bali Parking Building is one of the buildings that uses steel material as the main structure. The building which has a height of 13.97 meters, a width of 32.8 meters, and a length of 16.18 meters has a construction plan duration of 248 calendar days starting from July 2023. Known critical trajectory activities will be carried out a crashing program analysis with the aim of accelerating time by using one method, namely overtime work with a duration of 4 hours. Based on the analysis that has been carried out with the help of the Microsoft Project 2019 application, there are 16 lists of activities included in the critical trajectory. In writing this thesis, it will be mentioned in the form of a line code in Microsoft Project 2019, namely 569-573-579-580-581-606-585-586-590-591-595-596-600-601-602-612. In addition to knowing the list of critical path activities, this thesis also accelerates the duration with an additional 4 hours of overtime and calculates the total cost of the acceleration. After acceleration, it is known that the duration decrease is 61 days with a normal duration of 248 days to 187 days and shows a time efficiency of 0.245%. The total initial cost with normal duration is Rp 8,822,280,000.00 while if the project is accelerated, the project cost becomes Rp 8,901,216,104.5 by showing an additional cost of Rp 78,936,104.47.

Abstract

Road maintenance is a strategic effort to support community mobility and economic development. This study aims to determine the optimal duration and analyze the cost impacts of implementing the Time Cost Trade Off (TCTO) method. The method is applied through critical path analysis and adding overtime hours to reduce the project duration. Data is collected from project documents such as daily reports, S-curves, and cost budget plans, then analyzed using Microsoft Project software. The results show that the project duration can be shortened to 117 days with an additional cost of IDR 176,614,724.00, which is lower than the potential delay penalty of 1% per day. This adjustment leads to a time savings of 8.6% without causing significant changes to the project's organizational structure. The TCTO method proves to be a practical solution for addressing delays while maintaining a balance between time and cost.

Abstract

Prolonged road damage disrupts community mobility, logistics activities, and reduces road user safety. The road maintenance project on Jl. Ir. Soekarno in Blitar City, which was planned to be completed in 120 days with a budget of Rp1.16 billion, experienced a delay of 8 days due to time management constraints. This study aims to evaluate the use of the Time Cost Trade Off (TCTO) method to accelerate project completion without reducing the quality of work. The TCTO method is used to analyze the relationship between time and cost. This research proposes additional overtime working hours of 2 hours per day with the assumption of resources according to the Cost Budget Plan (RAB). The results show that with this method, the project can be completed in 117 days at a total cost of Rp1,342,177,724. Although it requires additional costs, this acceleration allows the project to be completed faster than the previous condition
