Abstract

Concrete structures that experience performance degradation require repair and strengthening to maintain their load-bearing capacity. One method that has gained attention is the use of composite materials, specifically Natural Fiber Reinforced Polymer (NFRP), which consists of adhesives reinforced with natural fibers. Pineapple fiber is a promising natural fiber for NFRP due to its abundance, low production cost, environmental friendliness, and high tensile strength. This study aims to investigate the adhesion behavior between NFRP composite materials and concrete, as well as to observe the failure modes of both concrete and NFRP under tensile loading. Concrete specimens measuring (100 x 100 x 300) mm were reinforced with pineapple fiber NFRP of (50 x 240) mm, with fiber orientations arranged in both unidirectional and random patterns. The results showed that the maximum tensile strength of the random pineapple fiber NFRP reached 31.59 MPa. The highest load capacity recorded was 4360 kg, observed in the LP3-SNS-C test specimen. The failure mode occurred as a fracture of the pineapple fiber NFRP in the center of the specimen’s cross-section on both sides.

Abstract

The city of Banda Aceh is experiencing rapid growth, especially in the transportation sector, as the population and daily mobility of people increase. This condition causes various traffic problems such as congestion, pollution, and safety. The Aceh Provincial Government through the Transportation Agency responded to this by providing the Trans Koetaradja Bus as an alternative to public transportation. This bus carries the concept of BRT-lite without a special lane, with the hope of reducing dependence on private vehicles. Although it is generally accepted, the use of Trans Koetaradja is still low due to limited route access and the absence of feeder transportation. This study aims to analyze the characteristics and travel behavior of Trans Koetaradja users and private vehicles in mandatory and non mandatory activities in Banda Aceh. The research was conducted in a quantitative descriptive manner using the revealed preference method with 400 respondents. The results showed that the majority of respondents were women aged 20–29 years old with a bachelor's education background and status as a student. The most dominant mode of transportation is motorcycles, used almost every day by respondents. The use of Trans Koetaradja is still low, with the majority of respondents only using it less than once a month. The average travel time to the bus stop is 2–4 minutes, and the dominant destination for mandatory activities is work, while for non mandatory activities is recreation. This underscores that the limited use of Trans Koetaradja is mainly due to access constraints, despite the presence of a well-defined potential user segment.

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
