Abstract

The type of material, mixture composition, and production process are among the factors that influence the strength of interlock bricks. In this study, interlocking bricks are used for the construction of residential wall structures. The interlocking brick mixture consists of cement, fly ash, sand, and water. The fly ash and sand used have a maximum diameter of 4.75 mm and are not subjected to calcination. Interlocking bricks measuring 30 cm x 20 cm x 10 cm are molded using a manual hydraulic press and cured for up to 28 days before being cut into test specimens measuring 5 cm x 5 cm x 5 cm. A total of 150 test specimens from 5 mix designs using water-cement ratios (WCR) of 0.3, 0.4, and 0.5 were utilized in this study. The objective of this research is to determine the quality levels of interlocking bricks based on compressive strength tests at 28 days of age. The quality levels are determined according to the Indonesian National Standard, SNI 03-0349-1989. Based on the compressive strength results, it was found that the average interlocking bricks with fly ash mixture achieved class III quality, indicating that they can only be used for non-structural wall applications.

Abstract

Classification and stratification of subsurface soils are critical aspects for a geotechnical site assessment to design and construct geotechnical structures. A probabilistic interpretation method is devised to adequately account for the uncertainty associated with subsurface soil categorization and stratification based on cone penetration test (CPT) data. CPT data is frequently directly employed in the construction of deep and shallow foundations, as well as a range of other purposes. It is advantageous to employ CPT data to create stratigraphic profiles as well, in order to generate more cost-effective designs. The method is demonstrated using CPT data from several locations in the Banda Aceh area. From limited CPT data, the approach accurately identifies subsurface soils in a 2D vertical cross-section. The objectives of this paper are to utilize CPT data to examine the soil profile in Banda Aceh, Indonesia. Additionally, soil parameters must be evaluated to obtain a better knowledge of Banda Aceh's soil conditions. The evaluation indicates that the average depth of the hard layer in the Kuta Alam District ranges from 5 to 8 meters beneath the ground surface. However, at certain locations, the hard soil stratum reaches a depth exceeding 18 meters. The findings are expected to be one source for determining the preliminary soil profile condition in Banda Aceh before doing additional soil investigation for construction design requirements.

Abstract

The durability of pavement is caused by the problem of surface drainage in every part of the highway, which may be different and requires consideration after special care depending on the location conditions. Good drainage is generally achieved by providing material gradations that are in accordance with adequate permeability with structural adequacy that depends on site conditions by taking into account the intensity of rain in the area. The purpose of this study was to study the permeability of falling head permeability (FHP) methods and the durability of the Marshall method from semi-flexible hardness using used tire rubber and natural zeolite as a substitute for asphalt and cement. The mix design of porous asphalt is started with determination of optimum asphalt proportion with open graded aggregat as spesified in Australian Asphalt Pavement Assosiation (AAPA) 2004.. The asphalt was then replaced with 3%, 4% and 5% waste tire rubber and the Marshall Test was conducted. The cement mortar with 0 %, 5 %, 10 %, 15 % and 20 % natural ziolite was injected to porous asplalt specimens. Permeability tests and durability are conditioned according to ASTM C67091a at 14 days of specimen age. The test results showed that the highest permeability value was obtained at 0.0529 cm / second and the highest durability was 91.45% in 15% of Aceh's natural zeolites. The value of durability is much higher than the required specifications of 75%.

Abstract

Reconstructing housing after a disaster is a demanding and intricate process, particularly when managing risks that affect project delivery timelines. The community-based approach, widely adopted in Indonesia, seeks to foster local participation but is often hindered by implementation challenges. This study aims to identify and analyse the critical risks contributing to delays in community-driven housing reconstruction projects in Pidie Jaya Regency, Aceh, Indonesia, as perceived by stakeholders. Research variables were developed sequentially through a literature review, semi-structured interviews, focus group discussions (FGDs), and questionnaires. A mixed-methods approach was employed, combining thematic analysis with descriptive statistics and indices, such as the frequency index (FI), severity index (SI), and risk importance index (RII). Seventy-one risk variables were identified, including 17 newly documented risks not previously addressed in the literature. Three variables were found to be particularly significant: shortage of facilitators, limited labour availability, and insufficient community construction skills. The findings contribute theoretically by broadening the understanding of operational risks during the construction phase and offer practical guidance for policymakers in developing more effective mitigation strategies, with implications for other developing nations utilising community-based reconstruction.
