The use of Mandar River water, apart from being a source of air for the surrounding community, is also used as a power plant, so that the Mandar River cannot be separated from the lives of some people who live in the border areas of the Mandar River. Over time, activities in the Mandar River border area have increased, especially in the construction of residences and other buildings such as residential buildings. This study aims to identify the use of space in the Mandar River border area and provide recommendations for spatial planning by zoning the use of space in the area and reducing the impact of flooding. The method used in this research is descriptive qualitative with spatial analysis. The results of this study are the zoning arrangements for regional activities in the form of conservation areas and border areas, while the zoning of cultivation areas are river conservation areas and agricultural and plantation areas. The border area of ​​the Mandar River for structuring more arrangements is right on the edge, where the area is a flood-prone area with relocation development or river normalization.</em></p> 2022-12-31T11:31:29+07:00 ##submission.copyrightStatement## http://jurnal.univrab.ac.id/index.php/racic/article/view/3004 IMPLEMENTASI KONSEP BIM 5D PADA PEKERJAAN STRUKTUR PROYEK GEDUNG 2022-12-31T12:59:32+07:00 Amalina Farhana 15511088@alumni.uii.ac.id Vendie Abma 15511088@alumni.uii.ac.id <p><em>Quantity take-off</em> menjadi hal yang sangat krusial karena menjadi dasar perhitungan yang berkelanjutan untuk tahap perencanaan. <em>Quantity take-off</em> digunakan untuk perhitungan BoQ atau estimasi biaya. Kesalahan dalam memperkirakan <em>quantity take-off</em> akan menyebabkan penyimpangan biaya dan atau adanya penyimpangan pada volume kebutuhan material. Diperlukan adanya perhitungan <em>quantity take-off</em> dan rencana anggaran biaya (RAB) yang efektif yang dapat dilakukan dengan metode BIM 5D. Penerapan konsep BIM memudahkan dalam ekstraksi <em>quantity take-off</em> langsung dari model 3D hingga kemudian terintegrasi dalam pengolahan estimasi biaya.&nbsp; Penelitian ini bertujuan untuk mendapatkan estimasi biaya dengan menerapkan konsep BIM 5D. Menggunakan bantuan <em>software</em> PriMus untuk membuat AHSP dan PriMus IFC untuk ekstraksi <em>quantity take-off</em>. Hasil yang didapatkan dari penelitian ini, bahwa dengan menggunakan konsep BIM 5D estimasi biaya yang dihasilkan terdapat selisih sebesar 7% lebih kecil dari anggaran biaya rencana awal. Hal tersebut terjadi dikarenakan perbedaan detail perhitungan volume pada perencanaan awal secara konvensional yang dihasilkan, serta beberapa diantaranya disebabkan karena data dari perencanaan modeling tidak memodelkan semua elemen konstruksi, yang kemudian muncul tanggung jawab berkelanjutan atas masalah tersebut oleh BIM modeler. Implementasi konsep BIM 5D dapat meningkatkan komunikasi, kolaborasi, dan menciptakan komitmen atau tanggung jawab yang berkelanjutan sehingga proses pengambilan keputusan menjadi lebih cepat dan tepat.</p> 2022-12-31T11:39:10+07:00 ##submission.copyrightStatement## http://jurnal.univrab.ac.id/index.php/racic/article/view/2805 PERENCANAAN SPESIFIKASI TEKNIS RUAS JALAN PROVINSI UNGGAN (KABUPATEN SIJUNJUNG)-PAMUSIAN (KABUPATEN TANAH DATAR) 2023-01-03T15:34:36+07:00 Bayu Budi Irawan bay.irawan@gmail.com Yossyafra Yossyafra yossyafra@eng.unand.ac.id Darwizal Daoed bay.irawan@gmail.com <p><em>The Unggan-Pamusian road is a road that connects Sijunjung and Tanah Datar Regencies.

This study aims to compare the value of the seismic base shear using the response spectrum method with the application of SNI 1726-2012 and SNI 1726-2019 in 6 cities on the Java Island, namely Banten, Jakarta, Bandung, Semarang, Yogyakarta, and Surabaya.

This research utilizes sawdust and portland cement as alternative materials to replace filler in the manufacture of Asphalt Concrete-Wearing Course (AC-WC) mixture. The purpose of this study was to determine the characteristics of the Marshall test on the AC-WC layer using a combination of sawdust and Portland cement filler. The method used is laboratory experiments with the initial step of finding the KAO value (Optimum Asphalt Content) with fillers using rock ash. Followed by replacing the filler with a combination of sawdust and portland cement. Variations in the mixture of Portland cement and sawdust, namely 0%-0%, 15%-85%, 25%-75%, 30%-70%, 40%-60%, 50%-50%, and 100% -0%. The specifications used in this study are&nbsp;the 2018 Revision 2 Public Road Specifications. The KOA obtained is 5.5%. Then the Marshall test was carried out on each variation to get the stability value and the mixed density value. Marshall test results with the best filler variations in this study were 60% sawdust and 40% portland cement. It can be seen that based on the stability value of the composition, the highest stability value was 1,278.64 kg, the MQ value was 491.78 kg/mm ​​and the melting value was 2.60 mm so it was concluded that the best AC-WC quality in this study found filler variations. 40% portland cement and 60% sawdust.</p> 2022-12-31T11:54:09+07:00 ##submission.copyrightStatement## http://jurnal.univrab.ac.id/index.php/racic/article/view/3005 PERANCANGAN PROGRAM ANALISIS STRUKTUR PORTAL BIDANG BERBASIS ANTARMUKA PENGGUNA GRAFIS 2022-12-31T12:59:32+07:00 Endryco Candyawan richardfrans.rf@gmail.com Richard Frans richardfrans.rf@gmail.com Hendry Tanoto Kalangi richardfrans.rf@gmail.com <p>Perhitungan manual dalam analisis struktur terbilang rumit, menghabiskan waktu yang lama, dan rentan terjadi kesalahan dalam proses perhitungan.
