Abstract

The Lombok Utara Regency DPRD Building Construction Project is a multi-story building construction project using conventional scheduling methods with an S-curve. In accordance with Government Regulation No. 16 of 2021 on the implementation regulations of Law No. 28 of 2002 on building construction, which mandates the use of BIM for medium and high-rise buildings. This study aims to investigate the use of BIM through Tekla Structures software in planning project scheduling based on Detailed Engineering Design (DED) data. The research methodology begins with the collection of relevant references and shop drawing data. Using the obtained data, a 3D model can be created using Tekla Structures 2025 software, followed by scheduling tasks using Tekla Task Manager. The advantages of scheduling using Tekla Structures include the ability to create detailed models and facilitate scheduling through its available features, which display visualizations of each stage of progress. Compared to conventional scheduling using an S-curve, Tekla Structures provides accurate information through the visualizations it displays. The scheduling results for the construction project of the Lombok Utara Regency DPRD Building using the S-curve required 139 calendar days, while using Tekla Structures software required 111 calendar days. This study demonstrates that BIM technology can significantly enhance construction project efficiency.

Abstract

Construction work is an important part of economic growth. Procurement of construction goods and services is one of the factors for successful development. One method used in procurement of construction services is direct appointment. Based on this, the government issued Presidential Regulation No. 16 of 2021 and Presidential Regulation No. 12 of 2021 concerning procurement of construction goods and services. The purpose of this study is to determine the stages of the direct appointment process and to determine the impact of changes in presidential regulations on the process of direct appointment of construction service providers. Thus, it is hoped that it can provide policy recommendations that can increase the effectiveness of construction service procurement. The research method uses quantitative descriptive research. The sampling technique uses purposive sampling, with data taken from the Gunung Rajak Village Library Building Construction project and questionnaires distributed to service providers, service providers, and the Gung Rajak village community who understand service procurement. The data processing is descriptive and the questionnaire data processing uses a Likert Scale. The results of this study are that the process of direct appointment activities in the Gunung Rajak village library building construction project was carried out well and structured. Then the results of the questionnaire analysis with a Likert Scale showed the percentage value of the respondents' attitudes above 80%, with a small standard deviation value, namely (between 0.626 - 0.484), and an average Likert scale value of 4. These results indicate that Presidential Regulation No. 12 of 2021 is considered better in the process of direct appointment of construction service providers compared to Presidential Regulation No. 16 of 2018.

Abstract

In the world of construction, concrete has a very important function as the main material due to its role in maintaining the strength and stability of the structure. This study aims to evaluate the effect of coarse aggregate size variations on the compressive strength of concrete and determine the most suitable size for use. The use of coarse aggregates is focused on granules that are retained on 3/4-inch and 3/8-inch sieves. The results showed that concrete with coarse aggregate retained in a 3/8 inch sieve had a higher compressive strength than 3/4 inch aggregate. At 3 days of age, the average compressive strength value reached 12,078 MPa for 3/8 inch coarse aggregate and 10,587 MPa for 3/4 inch aggregate. This difference continued at the 28-day lifetime compressive strength (the result of the 1971 PBI conversion), which was with an average value of 30,296 MPa for a 3/8 inch aggregate and 26,469 MPa for a 3/4 inch aggregate. This difference is due to a tighter distribution of patricles, reduced pore volume, and more optimal bonding of cement paste and aggregate. Therefore, the selection of coarse aggregate sizes needs to be adjusted to the purpose of construction.

Abstract

AbstrakPermasalahan lalu lintas merupakan salah satu konsekuensi dari rendahnya kesadaran pengguna jalan dalam menaati aturan yang berlaku. Untuk itu, pentingnya dilaksanakan kegiatan sosialisasi kepada masyarakat sebagai bentuk pengendalian non-fisik, dengan tujuan untuk meningkatkan kesadaran dan pemahaman masyarakat mengenai keselamatan berlalu lintas secara menyeluruh. Pelaksanaan kegiatan ini dilakukan pada Senin tanggal 26 Mei 2025 di Aula Kantor Desa Lembar Selatan dan dihadiri oleh 32 orang peserta, terdiri dari perangkat desa, kepala dusun dan perwakilan karang taruna yang ada di Desa Lembar Selatan yang juga bertindak sebagai mitra kegiatan ini. Metode pelaksanaan kegiatan ini terdiri dari empat tahapan yaitu tahap persiapan, tahap sosialisasi, tahap diskusi, serta tahap evaluasi dan monitoring. Kegiatan sosialisasi ini telah terlaksana dengan baik dan mendapat tanggapan positif dari peserta. Materi yang disampaikan dinilai bermanfaat, informatif, dan mampu meningkatkan kesadaran akan pentingnya mematuhi peraturan lalu lintas demi keselamatan diri sendiri maupun orang lain. Kata kunci: lalu lintas; sosialisasi; keselamatan. AbstractTraffic problems are one of the consequences of low awareness of road users in obeying applicable regulations. For this reason, it is important to carry out socialization activities to the community as a form of non-physical control, with the aim of increasing public awareness and understanding of traffic safety as a whole. The implementation of this activity was carried out on Monday, May 26, 2025 at the Lembar Selatan Village Office Hall and was attended by 32 participants, consisting of village officials, hamlet heads and representatives of youth organizations in Lembar Selatan Village who also acted as partners in this activity. The method of implementing this activity consists of four stages, namely the preparation stage, the socialization stage, the discussion stage, and the evaluation and monitoring stage. This socialization activity has been carried out well and received a positive response from the participants. The material presented was considered useful, informative, and able to increase awareness of the importance of obeying traffic regulations for the safety of oneself and others. Keywords: traffic; socialization; safety.
