Abstract

Kemajuan di bidang konstruksi yang sangat pesat membuat beton menjadi pilihan bahan struktur bangunan. Inovasi pembuatan beton menggunakan material berkelanjutan adalah sebagai upaya mengatasi permasalahan keterbatasan sumber daya yang ada saat ini. Beton pada umumnya terdiri dari bahan pengikat berupa semen. Abu sekam padi merupakan bahan pozzolan yang tinggi kandungan silika sehingga dapat berperan sebagai bahan pengikat pada campuran beton. Selain itu penggunaan limbah granit yang berasal dari batuan keras sebagai agregat kasar pada campuran beton dapat mengurangi permasalahan lingkungan.  Tujuan utama dari eksperimental ini adalah untuk menganalisis pengaruh penggunaan abu sekam padi dan limbah granit terhadap karakteristik beton. Abu sekam padi yang digunakan 5%,7,5%,10% sebagai substitusi semen, sedangkan limbah granit 5%, 7,5% dan 10% sebagai subtitusi agregat kasar. Hasil dari pengujian sifat beton segar bahwa abu sekam padi yang digunakan dengan persentase yang lebih tinggi dapat menurunkan workability dan meningkatkan kepadatan beton, serta mempercepat waktu pengikatan beton. Persentase optimum penggunaan abu sekam padi adalah 10% dan limbah granit 7,5% dengan hasil kuat tekan tertinggi dari beberapa variasi lainnya yaitu sebesar 28,07 MPa.

Abstract

Maps are complex data sets containing information on the location and objects of an area. Maps can show the distribution of various things on Earth, such as settlement patterns, mountains and others. ArcGIS is software that can be used in making village maps. Air Merah village is a village in Curup Tengah sub-district, Bengkulu, which until now has not had complete mapping for the area. The purpose of this service is to help present village data that can be accessed as spatial data information in planning development progress in Air Merah Village. Community service is carried out in stages of visiting the village head's office for administrative processes, conducting discussions with the team, collecting data through field surveys and interviews, making maps, and discussing the results of thematic maps, as well as holding a presentation to discuss the results of the map and handing over map printouts to village officials. This service activity was attended by lecturers, partners and students who were involved in all series of services both in the field and discussions, so as to produce village information maps. Based on the results of field surveys and modeling, Air Merah Village has an area of ± 10.7789 km2 and is located at latitude longitude -3.4801, 102.556365. Map making has received a positive response from the surrounding community and is expected to be able to provide location information and improve the inventory of Air Merah Village.

Abstract

Irigasi rawa salah satu sistem pengelolaan air yang dirancang untuk mengatur genangan, drainase, dan irigasi guna mendukung pertumbuhan tanaman di lahan rawa. Sistem ini melibatkan pembuatan jaringan tata air makro dan mikro yang bertujuan untuk meminimalkan dampak negatif genangan berlebih sekaligus menyediakan kebutuhan air bagi tanaman selama periode kering. Saluran irigasi rawa Delta Air Saleh terletak di desa Air Saleh Kabupaten Banyuasin dimana untuk jenis rawanya merupakan pasang surut dengan luas 11.077 hektar yang memiliki potensi pertanian. Penelitian ini bertujuan mengetahui bagaimana penilaian dan penanganan saluran irigasi rawa di delta Air Saleh. Metode yang dilakukan untuk penelitian ini adalah walktrough dari saluran primer sampai dengan saluran sekunder DIR Air Saleh. Hasil penelitian dari analisis kondisi DIR Air Saleh direkomendasikan untuk dilakukan pemeliharaan berkala. Kesimpulan dari penelitian ini adalah Pemeliharaan rutin sebanyak 1 saluran, Pemeliharaan Berkala sebanyak 3 saluran dari total keseluruhan 4 saluran primer.

Abstract

Soil water content significantly influences the bearing capacity of a soil. Bearing capacity is the ability of the soil to support construction loads. In a construction project, the subgrade must be able to support the planned loads and meet the requirements for successful construction. This experimental study aimed to determine the soil type, specific gravity, plasticity index, and the effect of changes in soil water content on the CBR values ​​of soaked and unsoaked soil from Lubuk Mumpo Village, Gunung Megang District, Muara Enim Regency. This study involved mixing native soil with mixture percentages of -10% OMC, -20% OMC, and +10% OMC, +20% OMC, to determine the CBR value. Ten soil samples were prepared for this test: 5 unsoaked and 5 soaked samples, based on SNI 1744-2012. The highest CBR values ​​were obtained at 10.94% for the -20% soaking variation (soaked) for 4 days and 5.33% for the -20% unsoaked variation (unsoaked) compared to the original soil. These results indicate that a 20% decrease in water content below the OMC increases the CBR value, while an increase in water content above the OMC decreases the CBR value.

Abstract

Steel angles play a vital role in energy infrastructure, especially in latticed transmission towers where they act as axial compression members. Their structural performance is strongly influenced by end restraints, bolt configurations, and slenderness ratios, which affect buckling behavior and compression strength. This study examines how the number and arrangement of bolts, along with slenderness variations, impact the displacement and stress response of steel angles under compression using nonlinear analysis and finite element modeling. The investigation highlights that different bolt patterns and slenderness ratios significantly alter the stability and load-bearing capacity of the members. Single-row bolt configurations tend to experience greater slippage compared to multi-row setups, indicating the importance of connection design in preventing premature failures. Overall, the findings emphasize the need for optimized bolt arrangements and slenderness control to enhance resistance to buckling and improve the overall efficiency and reliability of energy infrastructure systems under axial compression loads.
