Abstract

ABSTRACT: The construction of the Faculty of Medicine building is one of the projects undertaken by the University of Borneo Tarakan to provide adequate facilities for students, lecturers, and staff in carrying out teaching and learning activities. Several factors contribute to the possibility of occupational accidents during constructions, including the state of the equipment and materials utilized, as well as weather and environmental circumstances. This study analyzed risks using the HIRARC (Hazard Identification Risk Assessment and Risk Control) method in the Faculty of Medicine building construction project at the University of Borneo Tarakan. Data were obtained from a risk assessment questionnaire completed by OHS experts, site foreman, and construction workers. The results of the analysis identified 31 hazards out of 34 potential hazards, with a Risk Priority Number (RPN) value of 3,710. Based on the AS/NZS 4360:2004 standard, the risk level for this project falls under the moderate risk level. Therefore, it is recommended that all hazard be controlled according to the hierarchy of controls, namely substitution, engineering controls, administrative measure, and the use of personal protective equipment (PPE).Keywords: Risk Analysis, Faculty of Medicine, HIRARC.ABSTRAK: Proyek pembangunan gedung Fakultas Kedokteran merupakan salah satu proyek pembangunan yang dilakukan oleh Universitas Borneo Tarakan dengan tujuan untuk menyediakan tempat yang memadai untuk para mahasiswa, dosen  maupun staff  Fakultas Kedokteran dalam melaksanakan proses belajar-mengajar.

Abstract

ABSTRACT: The addition of floors and changes in building function can modify the load distribution and affect the capacity of structural elements, making it necessary to evaluate the existing structure to ensure that it can safely accommodate the new loading conditions. If the capacity is insufficient, strengthening is required, one method being the use of Carbon Fiber Reinforced Polymer (CFRP). This study includes the collection of existing structural data, structural modeling using analysis software, and the application of loads based on actual building conditions. The modeling results are used to assess the beam’s capacity under the additional loads, and if it does not meet the required strength, a strengthening system using CFRP is designed. In this research, an analysis was carried out on beam component B1 As 2-3 with a span length of 4.8 meters, considering an additional dead load from screed of 27.32 kN and an additional live load of 31.93 kN due to the functional change from office space to corridor. These added loads resulted in a new ultimate moment of 642.26 kNm, while the beam’s nominal moment capacity was only 530.29 kNm, indicating a required strengthening of at least 111.97 kNm. The analysis determined that three layers of CFRP were required, and with the CFRP installation, the new nominal moment capacity increased to 766 kNm, providing a total strength improvement of 44%.Keywords: Structural Strengthening, Beam Element, CFRP, Material, Reinforced Concrete. ABSTRAK: Penambahan lantai dan perubahan fungsi bangunan dapat mengubah distribusi beban dan kapasitas elemen struktur, sehingga diperlukan evaluasi untuk memastikan kemampuan struktur eksisting menahan beban baru. Bila kapasitas tidak mencukupi, perkuatan diperlukan, salah satunya menggunakan Carbon Fiber Reinforced Polymer (CFRP). Penelitian ini mencakup pengumpulan data eksisting, pemodelan struktur dengan bantuan perangkat lunak analisis struktur, serta penerapan pembebanan sesuai kondisi aktual. Hasil pemodelan digunakan untuk menilai kapasitas balok terhadap beban tambahan, dan jika tidak memenuhi syarat kekuatan, dirancang sistem perkuatan dengan CFRP. Pada penelitian ini dilakukan analisa komponen struktur balok B1 As 2-3 dengan panjang bentang 4.8 meter dengan penambahan beban mati akibat screed sebesar 27.32 kN dan beban hidup akibat perubahan fungsi ruang kantor menjadi koridor sebesar 31.93 kN. Dari penambahan beban tersebut didapatkan momen ultimate yang baru yaitu sebesar 642.26 kNm. Sedangkan momen nominal balok tersebut hanya sebesar 530.29 kNm, sehingga dibutuhkan perkuatan setidaknya sebesar 111.97 kNm. Dari hasil analisa didapatkan jumlah layer CFRP yang dibutuhkan yaitu sebanyak 3 layer, dengan penambahan CFRP didapatkan momen nominal yang baru yaitu sebesar 766 kNm. Dengan begitu didapatkan penambahan perkuatan sebesar 44%.Kata kunci: Perkuatan Struktur, Elemen Balok, CFRP, Material, Beton Bertulang.

Abstract

AbstractBased on SNI 03-0691-1996, paving block is a building material composition made from the mixture of Portland cement or similar hydraulic adhesives, water and aggregate with or without other additional material that will reduce the concrete quality. The burned rice husk ash will be used in this research. It aims to produce strong, environmental friendly and economical paving block. With the use of rice husk ash percentages as cement substitution are 5%, 10%, 15%, and 20%. The paving block mechanical characteristic test includes compressive strength, water absorption, and paving block shock resistance. This research is done at the designed age 7, 14, 21, and 28 of concrete. This result shows that the paving block with 5% of rice husk ash variation has compressive strength increased every designed paving block ages. Compressive strength test results are 32,85 Mpa, 37,92 Mpa, 39,55 Mpa, and 41,19 Mpa consecutively. Water absorption test resulted in an increased of paving block water absorption in every variation reach 6,77%, 7,32%,8,98%, 9,05%, and 9,30%. While for the shock resistance test did not increased with the adding of rice husk ash with the average blows are 4,33, 4,33, 4,33 and 4,67 blows every designed age until it caused the paving block cracked and broken.Key word: rice husk ash, paving block, compressive strength, water absorption, shock resistance.
