Abstract

The Functional Feasibility Certificate (SLF) is a legal requirement in Indonesia to ensure that buildings meet safety, health, and usability standards before being occupied, especially for public and commercial facilities. This study investigates the low adoption of SLF in public buildings in Banda Aceh, a mid-sized urban center in Indonesia. A qualitative case study approach was applied, involving direct observation and semi-structured interviews at four purposively selected sites: the BSI Landmark Building, Dr. Zainoel Abidin Regional General Hospital (Polyclinic), Kyriad Muraya Hotel, and Suzuya Mall. Results showed that only one building, the BSI Landmark had a valid SLF certificate. The remaining three lacked critical components such as fire doors, smoke detectors, and evacuation plans, despite the presence of basic safety infrastructure. Thematic analysis revealed three dominant barriers to certification: procedural complexity, limited institutional capacity, and low awareness among building managers. These findings highlight the need for streamlined digital certification systems, improved municipal support, and targeted regulatory outreach. The study contributes to the literature on urban safety governance in Indonesia and offers practical insights for strengthening disaster risk resilience and building compliance frameworks in Indonesian cities. Keywords: Functional feasibility certificate, Public building safety, Building regulation

Abstract

The use of electrical energy in buildings has the potential to cause wastage of electrical energy, such as lighting, lighting, electronic devices and equipment installed that does not comply with standards. This research aims to obtain building standardization by calculating the Energy Consumption Intensity (IKE) value, making savings on air and lighting systems, and calculating energy consumption costs. The savings that can be made in this research are savings by implementing energy conservation through technological improvement methods in lighting and air conditioning systems. On the procedures for implementing other savings by implementing energy saving behavior. Then calculate consumption costs using the financial assessment stages. Based on an audit of electrical energy in this office building, the IKE value obtained was 78.08 kWh per year. This value is considered efficient for office buildings. However, several conditions were found that caused energy waste, such as the use of fluorescent fluorescent lamps in the lighting system. The use of these lamps tends to be wasteful so they need to be replaced with LED TL lamps. The savings obtained on lighting are 55%. And in the cooling system the AC capacity does not match the area per floor. The savings obtained from air conditioning are 15% with the resulting kWh value being 511.2 kWh from the previous savings of 677.7 kWh.Keywords: Electrical Energy Audit, Energy Conservation, Energy Consumption Intensity

Abstract

The Maninjau Hydroelectric Power Plant (HEPP) faces technical challenges in its generator excitation system due to failures in the Type 13 electromechanical speed relay, a critical component in the excitation start-up sequence. This relay has not only lost accuracy but is also obsolete and difficult to procure in the market. Its malfunction poses the risk of excitation sequence failure, which may lead to damage in the Automatic Voltage Regulator (AVR), voltage meter disturbances, and even complete unit start-up failure.This study aims to replace the function of the electromechanical speed relay with a system utilizing generator rotational speed signals available through the Distributed Control System (DCS). The Root Cause Problem Solving (RCPS) method, field observation, and priority matrix analysis were employed to evaluate the most optimal replacement alternative. The results indicate that using a 24VDC relay based on signals from the Speed Sensor Gear (SSG) and digital signals from the DCS provides the best solution. The new system enables a more precise excitation process, easier installation, improved safety, as well as real-time monitoring and full integration with digital control systems.The implemented modification demonstrates that the excitation system becomes more reliable and efficient, effectively overcoming the previously frequent excitation sequence failures. Furthermore, the system is considered more economical and universal, while ensuring compatibility with future developments in digital-based power plant technology. Overall, this research makes a significant contribution to the modernization of hydroelectric control systems, in line with the sustainable and technology-driven development of national power infrastructure.Keywords: Speed Relay, DCS, Excitation System, Hydroelectric Power Plant, Generator Rotational Speed, Control Modernization

Abstract

Tofu liquid waste has a C/N ratio of 4.68 which is below the standard for biogas formation, namely 20-30. Increasing the C/N ratio of tofu liquid waste was carried out by adding raw materials that had a high C/N ratio, namely rice husks of 145.35. The amount of raw material mixed with tofu liquid waste and rice husks is determined by varying the C/N ratio according to standards with variations of 20, 22, 24, 26, 28, and 30 to get the best potential for biogas and electrical energy using the Anaerobic Fermentation method and software assistance. Superpro. The amount of rice husk raw material with a C/N ratio of 20, 22, 24, 26, 28, and 30 respectively 97.77 kg, 112.33 kg, 127.37 kg, 142.90 kg, 158.98 kg, and 175.60 kg. The best potential for biogas and electrical energy is at a C/N ratio of 30 with a raw material amount of 800 liters of tofu liquid waste and 175.60 kg of rice husk waste, amounting to 327.56 m3 and 1,539.53 kWh. It can be concluded that the raw material of rice husks can increase the C/N ratio of tofu liquid waste which is still below the standard for biogas formation, so that mixing tofu liquid waste with rice husks can increase the potential for biogas and electrical energy. Keywords: C/N Ratio, Tofu Liquid Waste, Rrice Husk, Biogas
