Abstract

Rumah Sakit Umum Daerah (RSUD) Meuraxa in Mibo is a Badan Layanan Umum Daerah (BLUD). Meuraxa Hospital is obliged to provide comfort and safety for patients. As a BLUD, almost all of its operational costs are sourced from the hospital's own revenue. The hospital building has a variety of ages, and the oldest has been operating for more than 17 years. Therefore, the reliability of the building began to decrease, and there were even building components in a damaged state. Even so, the standardization of hospital performance indicators in 2019 requires that hospital facilities and infrastructure are always in 100% condition. This can be realized by building buildings according to standards and carrying out building maintenance periodically/routinely.  Determining the extent of building damage in compliance with norms and regulations is the aim of the investigation (Peraturan Menteri Pekerjaan Umum Nomor: 24/PRT/M/2008). The method used is to conduct a field observation of building damage. The results of observation of the existing condition of emergency and intensive service building infrastructure obtained a building damage intensity of 1.32%. This condition is included in the category of light maintenance, which is ≤ 35% of the cost of building a new one. Damage is predominant to non-structural components.

Abstract

Industrial waste containing silica (Si), alumina (Al), and calcium (Ca) has potential as an alternative binder in concrete. These compounds form C-S-H and C-A-H gels in water-based systems, or Si-O-Si, Si-O-Al, N-A-S-H, and C-A-S-H gels in alkali-based geopolymer systems, enhancing strength and influencing setting time. One example is investigate FA from Nagan Raya (FANR) Coal-Fired Power Plantation in Aceh. This study evaluates its performance in geopolymer mortar through chemical and mechanical analysis. FANR is rich in Si and Al, improving mortar strength, while Ca content affects binding time. XRD analysis revealed crystalline phases in FANR and geopolymer binders, resulting in low reactivity. SEM analysis showed spherical particles with foggy surfaces, differing from typical glassy fly ash, which influences workability and alkali absorption. Mortar tests indicated the best performance at 8M NaOH and a Na₂SiO₃/NaOH ratio of 3.0, achieving 18.30 MPa compressive strength at 28 days. Higher alkali concentrations increased viscosity, reducing workability and final strength. Overall, FANR shows promise as a geopolymer binder with proper optimization of activator ratios.

Abstract

Cow feces on roads causes damage to asphalt on highways because cow feces contains a large amount of nutrients. The use of Styrofoam in asphalt is expected to improve the technical properties of a mixture. This study aims to determine the Marshall characteristics of asphalt concrete (AC-WC) mixtures with 5%, 7%, and 9% Styrofoam waste additions in 60/70 asphalt against asphalt weight with cow feces immersion for 30 minutes, 24 hours, and 48 hours. The best stability value was obtained with a 5% Styrofoam substitution, which was 1972.55 kg. The parameters for mixtures with and without Styrofoam, including stability, flow, MQ, density, VIM, VMA, and VFA, still meet the specifications of the 2018 Bina Marga standards. The durability value without substitution was 92.64% with ordinary water immersion and 90.80% with cow feces immersion. The durability value with varying Styrofoam percentages 5% was 95.56% and met the specifications set by Bina Marga in 2018, which is ≥ 90%.
