BIM addresses the limitations of conventional software like AutoCAD and Microsoft Excel, which are 2D-based and complicate coordination among different engineering fields. BIM, through the integration of 3D (modeling), 4D (scheduling), 5D (cost), 6D (sustainability), and 7D (operation and maintenance), offers a comprehensive framework for project planning, management, and evaluation. This study analyzes the efficiency of volume and cost estimation in the construction of the Balikpapan’s DP3 and DISDAG Building project in the city of Balikpapan using the BIM 5D concept with Autodesk Revit 2022 software. The research results indicate that volume and cost estimations with BIM 5D are more efficient compared to conventional methods. The concrete work volume with BIM is compared to that of conventional methods from the consultant, there is a saving of 4.92% for concrete works, and&nbsp; 5.16% of saving for rebar works. These findings demonstrate that the implementation of BIM 5D in Autodesk Revit is lower and more efficient in volume and cost estimation.</em></p> Celvin Adi Prastya Irna Hendriyani Reno Pratiwi Copyright (c) 2025 Celvin Adi Prastya, Irna Hendriyani, Reno Pratiwi https://creativecommons.org/licenses/by-nc-sa/4.0 2025-06-01 2025-06-01 7 1 17 24 10.31605/bjce.v7i1.4301 Pengaruh Repetisi Beban Lalu Lintas Harian Terhadap Nilai Kepadatan Perkerasan AC-WC Pasca Konstruksi https://ojs.unsulbar.ac.id/index.php/bjce/article/view/4205 <p><em>The compression process should be carried out carefully in each asphalt coating sheet, in addition to the availability of heavy equipment should be taken into account its productivity. Problems that are often faced by contractors in the field sometimes cause damage to heavy equipment and decrease in productivity, although the material mixture is already in accordance with the quality and the compression process follows the number of tracks planned, but the results of the field compression tests do not meet the specifications as long as the contractor in execution has to increase the amount of compression tracks and working hours of use of heavy equipment on the field. Concrete measures are needed to suppress the reduction in the efficiency of work so as not to affect increased costs and time. The daily additional load factor of traffic can be used as a parameter that helps the compression process, so in achieving the expected quality target does not always depend on the use of heavy equipment. This study analyzed the comparison of the percentage of AC-WC density to the repetition value of the load growth of post-sourcing traffic and the PHO time of the project. The results of the calculation showed that the AC - WC density value in segment 1 was 100.42%, while segment 2 was 99.73%, and segment 3 was 98.82%. Then the PHo time value of project 1 was 104.44% with a load repeat of 43.708,75 cesa, while in segment 2 it was 100.20% with load repeats of 1.277.57 cesa and in segment 3 it is 99.20%, with a charge repeat value of 1.368.75 cesa.</em></p> Dwiky Erlangga Puji Laila Ramadhan Saktiadin Saktiadin Copyright (c) 2025 Dwiky Erlangga, Puji Laila Ramadhan, Saktiadin Saktiadin https://creativecommons.org/licenses/by-nc-sa/4.0 2025-06-01 2025-06-01 7 1 25 31 10.31605/bjce.v7i1.4205 Analisis Data Oseanografi Pantai Parappe Kabupaten Majene dalam perencanaan Breakwater https://ojs.unsulbar.ac.id/index.php/bjce/article/view/5064 <p>Penentuan lokasi dan dimensi bangunan pelindung pantai khususnya bangunan pemecah gelombang harus memperhatikan data oseanografi agar bangunan dapat berfungsi secara efektif untuk melindungi pantai dari kerusakan akibat gelombang dan arus.

Eight sediment samples were analyzed using granulometric methods and statistical approaches by Folk &amp; Ward (1957), combined with log-probability curve interpretation based on Visher (1969). Results indicate that upstream sediments are predominantly coarse-grained with poor to moderate sorting and exhibit multimodal grain size distributions. In contrast, downstream sediments are finer, better sorted, and show unimodal distributions, indicating dominant suspension deposition. Log-probability analysis identified the presence of three major transport mechanisms (traction, saltation, suspension), varying between observation stations. This study demonstrates that integrating grain size statistics and log-probability curves effectively interprets fluvial sedimentation dynamics and depositional environment transitions.</em></p> Herni Suryani Elvira Jamal Yusman Copyright (c) 2025 Herni Suryani, Elvira Jamal, Yusman https://creativecommons.org/licenses/by-nc-sa/4.0 2025-06-01 2025-06-01 7 1 42 50 10.31605/bjce.v7i1.5077 Deagregasi Potensi Earthquake Ground Motion pada Jalan Tol untuk Periode Ulang Gempa 1000 Tahun https://ojs.unsulbar.ac.id/index.php/bjce/article/view/4994 <p>Port access toll roads, particularly those under the National Strategic Project (PSN), are developed to ease export-import congestion and reduce logistics costs, enhancing industrial competitiveness. This study highlights the importance of earthquake-resistant infrastructure planning through performance-based analysis, which requires time history analysis using recorded ground motions. The objective is to identify appropriate ground motion records for such analysis. The method involves disaggregating average magnitude (M) and distance (R) values to represent seismic sources. Results indicate that M = 6.7 and R = 98 km adequately represent major seismic sources, including Megathrust, Benioff, and Shallow Crustal Faults. The peak ground acceleration (PGA) at bedrock for a 1000-year return period is 0.237 g. The selected ground motion record, with M = 6.7, R = 98 km, and PGA = 0.237 g, was obtained from the USGS database, specifically from the Hilo, HI – USDA Laboratory station (code: NP2818).</p> Fitriana Sarifah Yusep Ramdani Asep Kurnia Hidayat Copyright (c) 2025 Fitriana Sarifah, Yusep Ramdani, Asep Kurnia Hidayat https://creativecommons.org/licenses/by-nc-sa/4.0 2025-06-01 2025-06-01 7 1 51 59 10.31605/bjce.v7i1.4994 Strategi Pengembangan Sistem Transportasi Khusus Pegawai Pemerintah Kota Palu: Pendekatan Efisiensi dan Aksesibilitas https://ojs.unsulbar.ac.id/index.php/bjce/article/view/5092 <p><strong>Abstrak<br></strong>Urbanisasi yang pesat di Kota Palu telah menimbulkan tantangan terhadap mobilitas pegawai pemerintah, yang masih bergantung pada kendaraan pribadi.

Dengan menggunakan analisis GIS, dirancang rute angkutan khusus dari 18 wilayah asal perjalanan utama menuju Balai Kota dengan waktu tempuh maksimal 20 menit. Studi ini merekomendasikan pengembangan sistem transportasi pegawai berbasis kebutuhan pengguna, dengan fokus pada keterjangkauan biaya, kecepatan layanan, dan kemudahan akses, guna mendukung efisiensi perjalanan dan keberlanjutan mobilitas di Kota Palu.<br><strong>Kata Kunci</strong>: Aksesibilitas, Angkutan khusus, &nbsp;Efisiensi mobilitas, Perencanaan rute, Transportasi pegawai</p> Ellyni Dwi Fortuna Siti Malkhamah Muhammad Zudhy Irawan Copyright (c) 2025 Ellyni Dwi Fortuna, Siti Malkhamah, Muhammad Zudhy Irawan https://creativecommons.org/licenses/by-nc-sa/4.0 2025-06-01 2025-06-01 7 1 60 66 10.31605/bjce.v7i1.5092 Analisis Daya Dukung Lapisan Subgrade Jalan Dengan Metode CBR Soaked dan Unsoaked https://ojs.unsulbar.ac.id/index.php/bjce/article/view/4246 <p>Tanah subgrade sangat penting dalam menentukan daya dukung tanah, karena menahan beban dari bangunan dan kendaraan. Jika subgrade memiliki daya dukung yang rendah, dapat menyebabkan penurunan dan deformasi, yang mengakibatkan retakan, lubang, serta peningkatan risiko kecelakaan akibat kerusakan jalan. Metode California Bearing Ratio (CBR) sering digunakan untuk mengevaluasi kekuatan tanah. Penelitian ini bertujuan untuk menentukan nilai daya dukung lapisan tanah dasar jalan desa di Kabupaten Karawang dengan menganalisis sifat indeks tanah dan nilai CBR (rendaman dan tanpa rendaman). Hasil uji menunjukkan batas cair 92,67%, indeks plastisitas 47,54%, dan berat jenis 2,57 g/cm³, menunjukkan tanah lempung dengan plastisitas tinggi dan potensi ekspansif yang besar. Nilai CBR rendaman adalah 7,99%, sedangkan nilai CBR tanpa rendaman mencapai 40,9%, mengklasifikasikan tanah sebagai kategori sedang untuk perencanaan subgrade jalan. Stabilisasi tanh tetap perlu dilakukan untuk mendukung beban berat dalam kondisi basah dan kering.</p> Neneng Winarsih Nurani Masyita Firda Ainun Nisah Dewita Briliansi Vina Nurhotimah Copyright (c) 2025 Neneng Winarsih, Nurani Masyita, Firda Ainun Nisah, Dewita Briliansi, Vina Nurhotimah https://creativecommons.org/licenses/by-nc-sa/4.0 2025-06-01 2025-06-01 7 1 67 73 10.31605/bjce.v7i1.4246 Strategi Pengembangan Kawasan Terminal Majene Berbasis TOD (Transit Oriented Development) https://ojs.unsulbar.ac.id/index.php/bjce/article/view/4943 <p><em>The development of terminals as transportation hubs has an important and strategic role in growing the economy of urban areas. TOD (Transit Oriented Development) is a spatial planning concept that focuses on the development of transit areas around public transportation hubs such as train stations, bus terminal, or mass transportation stops including the Majene terminal. Based on BPS data, the increase in Majene terminal activity in the last five years was due to the high population (0,15%/year) and the number of motorized vehicles (26,7%/year). Several problems faced such as the status of terminal which has changed of its function, minimal of facilities, and infrastructure and the absence of attractions around the terminal area. This study aims to (1) to identify the suitability of the TOD concept in the Majene terminal area, (2) to formulate a TOD concept based on Majene terminal area development strategy which is identified through the regulation of Ministry of ATR BPN No. 16 of 2017 concerning the Development of Transit Areas. &nbsp;</em></p> Astinawaty Astinawaty Zul Asriana Copyright (c) 2025 Astinawaty Astinawaty, Zul Asriana https://creativecommons.org/licenses/by-nc-sa/4.0 2025-06-01 2025-06-01 7 1 74 80 10.31605/bjce.v7i1.4943
