Abstract

Keterampilan kerja yang berkualitas sangat penting untuk bersaing dalam pasar global yang semakin terhubung dan canggih. Pemerintah Indonesia telah meluncurkan program SMK Pusat Keunggulan melalui Dirjen Vokasi untuk menjawab kebutuhan tersebut. Program ini bertujuan memperbaharui pendidikan vokasi sesuai dengan tuntutan industri. Terdiri dari tiga kategori, yaitu SMK Pusat Keunggulan 2021, SMK Pusat Keunggulan Lanjutan, dan SMK Pusat Keunggulan Skema Pemadanan, yang memberikan dukungan infrastruktur serta pengembangan kapasitas fisik dan non-fisik. Tujuan program ini adalah membentuk hubungan antara pendidikan dan dunia kerja melalui pelatihan guru, pengembangan kurikulum, dan penerapan Teaching Factory. Di SMKN 1 Sekampung, tim dari Fakultas Teknik UMMAT memberikan bimbingan selama tiga bulan dengan fokus pada koordinasi, proyek industri, dan Bursa Kerja Khusus (BKK). Dampaknya terlihat dari peningkatan hasil tracer study dari 80% menjadi 90%, panduan sarana prasarana baru, serta penyesuaian kurikulum dengan konsep Merdeka Belajar. Meskipun dihadapkan dengan tantangan teknis dan non-teknis, upaya ini telah berhasil meningkatkan kualitas pendidikan serta kesesuaian kurikulum dengan kebutuhan industri. Kolaborasi antara sekolah, dinas pendidikan, dan perguruan tinggi menjadi kunci sukses dalam mengatasi tantangan tersebut. Program ini menjadi contoh bagus dalam meningkatkan kualitas pendidikan vokasi dengan mengintegrasikan dunia pendidikan dan industri, yang diharapkan dapat menjadi model untuk program serupa di masa depan.

Abstract

Masjid merupakan bangunan tempat beribadah bagi umat Islam. Hampir setiap Dusun di Pulau Lombok khusunya, memiliki Masjidnya masing-masing dan salah satunya adalah Dusun Mentokan. Dusun ini berada di Desa Darek Kecamatan Praya Barat Daya, Kabupaten Lombok Tengah. Didasari oleh peningkatan jumlah penduduk dan umur bangunan yang sudah cukup tua, maka masyarakat setempat bersepakat untuk melakukan kegiatan rehab pada Masjid Nurul Huda. Namun, hal tersebut menjadi suatu kegiatan yang cukup berat bagi masyarakat karena didasarkan kepada: keterbatasan anggaran, pengoptimalan pemanfaatan dana dan SDM masyarakat yang notabene sebagian besar adalah petani dan buruh harian lepas. Sebagai tenaga pengajar dalam bidang Teknik Sipil dan aktif dalam bidang pembangunan, serta sebagai bentuk pengabdian keilmuan kepada masyarakat, maka dilakukan pendampingan dalam kegiatan rehab Masjid Nurul Huda Dusun Mentokan. Dengan dimulai dari kegiatan: pengukuran; brainstorming dengan masyarakat; rembuk dan pendampingan pembuatan DED; dan pendampingan pelaksanaan pembangunan, maka rehab terhadap Masjid Nurul Huda Dusun telah diselesaikan dengan pengelolaan dana yang baik, tepat mutu dan guna.

Abstract

This research was conducted to review the feasibility of beach sand from the Batu Bolong village of West Lombok Region as an alternative fine aggregate in concrete manufacturing. The background of this research is based on the decreasing supply of sand from rivers and mountains. The main objective of this research was to evaluate the compressive strength of concrete using beach sand, both with and without a washing process, and assess whether this material could be applied in structural construction. In addition to technical aspects, the local community's habit of utilizing beach sand is also part of the consideration in this study. The result oh the tests showed that the compressive strength of normal concrete without admixtures at 3, 7, and 28 days of age were 16.42 MPa, 19.21 MPa, and 23.39 MPa, respectively. The addition of the "BETON MIX" admixture increased the strength to 20.78 MPa, 23.38 MPa, and 26.44 MPa. Meanwhile, concrete using washed beach sand showed compressive strengths of 22.67 MPa, 23.61 MPa, and 25.16 MPa. The concrete with unwashed beach sand produced strengths of 21.72 MPa, 22.40 MPa, and 23.08 MPa. The results of this study indicate that sand from Batu Bolong beach has the potential to be a substitute for fine aggregate in concrete. However, its use must still consider ecological impacts so as not to disturb the balance of the coastal environment.

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.
