Abstract

Road paving works play a critical role in supporting economic growth and public welfare, as mandated by Government Regulation No. 34/2006. However, the implementation of such projects is often hindered by road damage and the limited availability of heavy equipment and skilled operators. This study aims to identify the types of heavy equipment used, calculate their production capacity, and analyze the duration of major construction phases. The method applied is time study, using primary data collected from field surveys and secondary data from supporting documents such as construction drawings and literature. The results indicate that each type of equipment showed varying levels of productivity deviation between planning and actual implementation. Dump trucks increased in productivity from 2.98 m³ to 3.49 m³, while motor graders decreased from 366.18 m³ to 317.475 m³. Significant increases were observed in the vibrator roller and air compressor, whereas asphalt finisher, tandem roller, and pneumatic tired roller experienced substantial drops in productivity. The asphalt sprayer maintained consistent performance at 4.980 liters/hour. In conclusion, heavy equipment productivity is significantly influenced by equipment type, field conditions, and operational coordination, all of which are crucial to ensuring timely project completion with quality standards met.

Abstract

Balok beton bertulang merupakan elemen struktural fundamental dalam berbagai jenis bangunan. Namun, seiring waktu, balok ini rentan mengalami degradasi dan kerusakan akibat berbagai faktor lingkungan dan beban operasional, yang seringkali memerlukan upaya perbaikan dan perkuatan untuk memulihkan atau meningkatkan kapasitas layannya. Penelitian ini bertujuan untuk menganalisis potensi penggunaan komposit serat alam sebagai material alternatif yang efektif untuk perbaikan dan perkuatan balok beton bertulang. Berbagai jenis serat alam, seperti serat bambu, rami, dan sutra, beserta matriks pengikatnya, dieksplorasi potensinya untuk aplikasi struktural. Metodologi penelitian melibatkan pembuatan sampel balok beton bertulang yang mengalami kerusakan terkontrol, kemudian dilakukan perkuatan eksternal menggunakan komposit serat alam. Sampel yang telah diperkuat ini kemudian diuji lentur untuk mengevaluasi peningkatan kapasitas beban, kekakuan, dan daktilitas dibandingkan dengan balok kontrol tanpa perkuatan. Hasil analisis menunjukkan bahwa komposit serat alam mampu memberikan peningkatan signifikan pada kinerja lentur balok beton bertulang yang rusak, dengan pola kegagalan yang bervariasi tergantung pada jenis serat dan metode aplikasi. Temuan ini mengindikasikan bahwa serat alam merupakan material yang menjanjikan untuk rehabilitasi infrastruktur beton, menawarkan solusi yang lebih berkelanjutan dan ramah lingkungan. Penelitian ini memberikan kontribusi pada pengembangan material konstruksi hijau dan strategi perbaikan struktur yang efisien.

Abstract

A dam is a structure designed to ensure the sustainable availability of water supply. One dam that plays a significant role in this regard is the Keuliling Dam, which makes a major contribution to meeting the water needs of the community. Despite offering numerous benefits, the existence of a dam also poses potential risks that must be properly anticipated. As part of mitigation efforts and maintenance planning, analysis of the buffer zone and greenbelt is essential at Keuliling Dam. This study employs a combination of primary and secondary data to support the evaluation process of the buffer zone and greenbelt conditions at the dam. The aim of this analysis is to assess each component based on observation results using a condition index approach. The assessment process begins with identifying damage in each subcomponent, followed by assigning scores according to the level of damage observed. Based on the analysis results, the condition index for the buffer zone and greenbelt is recorded at level 4, which indicates minor damage. This value reflects the current condition of these two components and serves as a critical reference for the planning and implementation of maintenance activities to ensure the dam's functionality is properly maintained.

Abstract

The construction of the People's School Building in Jeulikat Village, Blang Mangat District, Lhokseumawe City, Aceh Province is one of the government's strategic programs to improve educational facilities. The site conditions consist of uneven topography and clayey sand soil requiring proper retaining wall and foundation design. This study aims to optimize retaining wall and foundation systems based on soil parameters, structural loading, and Indonesian geotechnical standards. A quantitative analytical method was employed using soil investigation data, laboratory testing, and calculations based on Rankine Earth Pressure Theory, Terzaghi Bearing Capacity Theory, Meyerhof Method, and Indonesian National Standards. The results indicate that a cantilever retaining wall with a height of 4 meters provides safety factors against sliding, overturning, and bearing capacity of 2.15, 2.48, and 3.12 respectively, satisfying engineering requirements. Furthermore, a spread footing foundation measuring 2.0 × 2.0 meters provides an ultimate bearing capacity of 845.36 kN with a safety factor of 3. The optimized design reduces concrete consumption by approximately 12.4% compared with conventional designs while maintaining structural safety
