Abstract

This study provides an understanding of the advantages of reinforced concrete in the construction of multi-story buildings in Banda Aceh. The objective of this research is to improve the efficiency of constructing the Class I Immigration Office Building in Banda Aceh by replacing the main structural system from steel to reinforced concrete. This change was carried out in accordance with the SNI 2847:2019 standard, utilizing the ETABS application for the design and analysis process.The results show that the total building weight in the existing condition (steel structure) is 1,594,043.95 kg, while using reinforced concrete increases the weight to 2,631,222.38 kg. At portal 5-5, the differences in bending moment and shear force between the steel and reinforced concrete structures are significant, with values of -2.9559 kNm and -80.0447 kNm for bending moment, and 3.5657 kN and 29.1996 kN for shear force, respectively. Additionally, the maximum lateral displacement in both X and Y directions is lower in the reinforced concrete structure compared to the steel structure. The axial force at portal 5-5 also shows an increase from -492.0887 kN (steel structure) to -949.2849 kN (reinforced concrete structure). These findings indicate that the use of reinforced concrete provides better stability, capacity, and overall structural performance compared to the steel structure

Abstract

Currently, the availability of petroleum and natural gas as non-renewable energy sources is steadily decreasing. One alternative energy source that can be developed for the future is bioethanol, as it is renewable and environmentally friendly. The kumbi fruit (Voacanga foetida (Bl.) ROLFE) is a potential raw material for bioethanol production due to its cellulose content, which can be converted into bioethanol. The objective of this study was to investigate the effect of acid concentration on the hydrolysis process in the production of bioethanol from kumbi fruit. In this study, hydrolysis was carried out using HCl at concentrations of 1%, 2%, 3%, 4%, and 5% (v/v) at 70°C for 90 minutes. To determine the reducing sugar content produced, the hydrolysate was analyzed using UV-Vis spectrophotometry. The hydrolysate was then fermented using baker's yeast containing Saccharomyces cerevisiae for 72 hours. The fermentation product was distilled at 78°C, and the obtained bioethanol was analyzed using GC-MS. The results showed that the highest reducing sugar concentration was obtained at 2% acid concentration, amounting to 7.18 g/L, while the highest crude bioethanol yield was 47.64%, achieved at 4% acid concentration with a reducing sugar content of 1.04 g/L.

Abstract

Pneumonia remains one of the leading causes of death among children under five in Indonesia. In Garut Regency, a total of 9,865 pneumonia cases were recorded in 2023, with Kadungora Primary Health Center reporting 276 cases of acute respiratory infection (ARI) with pneumonia in children under five during the same period. Most cases experienced delays in treatment due to low family knowledge and awareness regarding early symptoms and initial actions to take. This study aims to describe family understanding, health-seeking behaviors, and factors influencing the management of ARI pneumonia in children under five. A qualitative method was employed through in-depth interviews with two families of children diagnosed with pneumonia and two local healthcare workers. The results revealed that most families failed to recognize the early signs and symptoms of pneumonia, tended to rely on traditional remedies, and had limited access to health information. However, families who had received health education from community health volunteers responded more promptly and appropriately in seeking medical care. Key factors influencing family behavior included socioeconomic conditions, knowledge level, and access to information. This study highlights the crucial role of active healthcare provider involvement and community-based education in increasing awareness and promoting timely management to reduce morbidity and mortality from pneumonia in children under five.
