Abstract

Buildings that have been in use for a long time should be inspected regularly to ensure that they are safe to use and robust. In the field, visual inspections are often performed on parts of structures such as columns, beams, and plates. Measurement of the propagation time of ultrasonic pulses in concrete and relate it to the quality and strength of the material. A weak positive correlation is shown with a multiple value of R 0.324475. Every 1 m/s increase in the UPV value will increase the Hammer Test result by 0.00755 MPa. However, this relationship is weak because the UPV only accounts for 10.5% of the change in the Hammer Test results. The ultrasonic wave speed and the bounce result of the hammer can be affected by uneven concrete, such as the presence of cavities, material separation, or large gravel. This condition can also be seen during visual examination. STUDI KORELASI ANTARA UPV DAN HAMMER TEST DALAM MENENTUKAN LAIK FUNGSI STRUKTUR BANGUNANBangunan yang telah digunakan dalam jangka waktu lama harus diperiksa secara berkala untuk memastikan bahwa bangunan tersebut aman digunakan dan memiliki ketahanan yang baik. Di lapangan, pemeriksaan visual sering dilakukan pada bagian-bagian struktur seperti kolom, balok, dan pelat. Pengukuran waktu rambat gelombang ultrasonik dalam beton digunakan untuk menghubungkan nilai tersebut dengan kualitas dan kekuatan material. Hasil menunjukkan adanya korelasi positif yang lemah dengan nilai R sebesar 0,324475. Setiap kenaikan 1 m/s pada nilai UPV akan meningkatkan hasil Hammer Test sebesar 0,00755 MPa. Namun, hubungan ini tergolong lemah karena UPV hanya menjelaskan 10,5% dari perubahan hasil Hammer Test. Kecepatan gelombang ultrasonik dan hasil pantulan hammer dapat dipengaruhi oleh ketidakrataan beton, seperti adanya rongga, pemisahan material, atau kerikil besar. Kondisi ini juga dapat diamati melalui pemeriksaan visual.

Abstract

Construction projects involving heavy equipment, work at heights, and hazardous conditions are inherently high-risk, making safety management crucial. This study identifies hazards related to work accidents at the KAI Boutique Hotel Cihampelas project using the HIRARC (Hazard Identification, Risk Assessment, and Risk Control) method. The research applies a mixed-method approach, combining site observations, interviews, and questionnaires with project stakeholders. Statistical analysis and risk mapping classify risks based on severity and probability. Findings reveal 29 identified risks across ten work categories, including six high-risk items, 20 medium-risk items, and three low-risk items. The study emphasizes the need for consistent safety measures such as protective equipment, safety training, and adherence to standard procedures. The research’s novelty lies in its tailored HIRARC application in a specific construction context, offering actionable insights into mitigating occupational hazards and enhancing site safety.

Abstract

Using the Greenship Existing Building standard from the Green Building Council Indonesia (GBCI), this study assesses Green Building implementation in the FEB (Faculty of Economics and Business) and FP (Faculty of Agriculture) Buildings at Campus 1, Universitas Swadaya Gunung Jati. A quantitative-descriptive method was employed, with primary data from interviews, observations, and measurements of temperature, humidity, lighting, and airflow. Secondary data included building plans, water records, and operational documents. Results showed campus Green Open Space (RTH) at 31.94%, meeting Minister of Public Works Regulation No. 05/PRT/M/2008 (?30%). Average temperature (26.31°C) and humidity (53.09%) were comfortable, while lighting (394.418 lux) exceeded SNI 03-6197-2000 public area standards (100–300 lux). Water efficiency (6.44%) met basic needs but fell short of Greenship criteria. Energy intensity (1,413 kWh/year) surpassed SNI limits (?250 kWh/year), failing efficiency standards. Buildings excel in green space, thermal comfort, and lighting but need improvements in energy and water management to fully meet Greenship criteria. Recommendations: rainwater harvesting, energy-efficient equipment, and optimized operations aligned with sustainable campus principles.

Abstract

Environmental degradation and the rising energy demand in the building sector have underlined the urgency of implementing green building principles to mitigate ecological impacts and support long-term sustainability. This study aims to assess the sustainability performance of the Additional Building at Universitas Swadaya Gunung Jati using several evaluative parameters, including green open space, water efficiency, thermal comfort, lighting, carbon emission control, and energy performance. A quantitative-descriptive approach was employed using field measurements, direct observations, documentation, and verification interviews based on the Greenship Existing Building Version 1.1 standard issued by the Green Building Council Indonesia. The findings reveal that the building demonstrates strong compliance in terms of green open space (92.24%), optimal natural lighting (256.66 lux), and low OTTV values (16.91 W/m²), indicating efficient thermal resistance and minimal heat transfer through the building envelope. Conversely, water efficiency remains suboptimal due to the absence of alternative water management systems and roof tank infrastructure, leading to full reliance on electrical pumping. Thermal comfort also requires improvement since indoor temperatures and humidity exceed recommended benchmarks, which may influence user well-being and productivity. Overall, this study provides a comprehensive sustainability performance assessment and identifies key improvement indicators that can drive the development of a more energy-efficient and environmentally responsible campus. The results reinforce the strategic role of green building implementation in educational facilities as a foundation for future sustainable development.
