Abstract

Efforts to improve the efficiency of planning and cost control in small- to mediumscale construction projects in rural areas, the digital approach through Building Information Modeling (BIM) 5D offers a promising alternative. This study aims toanalyze the efficiency of material volume and cost estimation using the BIM 5D-based software Tekla Structures, with a case study on the construction project of the Gunung Rajak Village Library Building, Sakra Barat District, East Lombok Regency. The secondary data used include Shop Drawings and the Bill of Quantities (BoQ) btainedfrom the implementing contractor. The structural modeling was carried out using Tekla Structures to automatically generate estimates of concrete volume and reinforcement weight, which were then compared with conventional methods tomeasure differences and efficiency. The analyzed structural elements include foundations, tie beams, columns, beams, floor slabs, and the roof. The results show that the use of BIM 5D produces more accurate volume and cost estimations andaccelerates the calculation process. The  ifferences in concrete volume reached 18.14%, reinforcement weight 3.05%, and roof volume 9.53%, while cost efficiency was around 14.8% compared to the conventional method. These findings indicate that the implementation of BIM 5D has the potential to improve material and budget efficiency, although its application in rural areas still faces technical and human resource constraints.

Abstract

AbstrakMasjid merupakan tempat ibadah yang juga berfungsi sebagai pusat kegiatan sosial dan pendidikan. Dalam konteks Masjid Nurul Huda di Dusun Mentokan, Desa Darek, Kabupaten Lombok Tengah, terdapat kebutuhan untuk pengembangan fasilitas akibat meningkatnya jumlah penduduk dan kondisi bangunan yang sudah tua. Tim pengabdian dari Program Studi Teknik Sipil Universitas Muhammadiyah melakukan pendampingan desain masterplan untuk merespons kebutuhan tersebut. Metodologi yang digunakan mencakup pengumpulan data, analisis kebutuhan, dan perancangan konsep, dengan melibatkan masyarakat dalam setiap tahap. Hasilnya menunjukkan bahwa masyarakat menginginkan ruang multifungsi untuk kegiatan pendidikan dan sosial. Selain itu, masterplan yang dihasilkan juga mempertimbangkan aspek keberlanjutan dengan memanfaatkan sumber daya secara efisien. Partisipasi masyarakat dalam perencanaan terbukti meningkatkan rasa memiliki dan tanggung jawab terhadap masjid, sehingga diharapkan masjid tidak hanya berfungsi sebagai tempat ibadah, tetapi juga sebagai pusat kegiatan yang bermanfaat bagi komunitas. Kata kunci: masjid; pengabdian kepada masyarakat; masterplane. AbstractMosques are places of worship that also function as centers for social and educational activities. In the context of the Nurul Huda Mosque in Mentokan Hamlet, Darek Village, Central Lombok Regency, there is a need for the development of facilities due to the increasing population and the condition of the old building. The service team from the Civil Engineering Study Program, University of Muhammadiyah assisted in the design of a master plan to respond to these needs. The methodology used includes data collection, needs analysis, and concept design, by involving the community at every stage. The results show that the community wants a multifunctional space for educational and social activities. In addition, the resulting masterplan also considers sustainability aspects by utilizing resources efficiently. Community participation in planning has been proven to increase the sense of ownership and responsibility for the mosque, so it is hoped that the mosque will not only function as a place of worship, but also as a center of activities that are beneficial to the community. Keywords: mosque; community service; masterplane.
