Abstract

The quality of the sand used for the concrete mixture can affect the compressive strength produced by the concrete. This study aims to determine the amount of compressive strength and modulus of elasticity of concrete with quarry sand material Km.14 Sorong City and sand quarry from other regions, namely Tobelo North Halmahera quarry sand. This study used an experimental method with a total of 18 selinder-shaped test objects consisting of 3 samples aged 7 days, 3 samples aged 14 days and 3 samples aged 28 days for each quarry Modulus of elasticity testing was only carried out on concrete aged 28 days. All material testing until the manufacture and tests of compressive strength and modulus of elasticity of cylindrical samples are carried out at the Civil Engineering Concrete Laboratory of the University of Muhammadiyah Sorong. From the results showed the average compressive strength produced between sand Km.14 of Sorong city and Tobelo sand was 8.78 Mpa: 11.13 Mpa for 7 days old, 10.66 Mpa: 12.83 Mpa for 14 days old and 11.23 Mpa: 13.78 Mpa for 28 days old. In addition, based on concrete strain testing, it can be seen that the higher the compressive strength or stress of the concrete, the higher the strain value.

Abstract

Arar Village, located in Sorong Regency, has abundant marine resource potential, especially in the catch of cassia shrimp. However, the cassia shrimp processing process still faces obstacles, especially in the drying stage, which is carried out traditionally, thus affecting the quality of the product. This study aims to improve the quality and cleanliness of cassia shrimp processed products through the application of stainless steel drying tables. The implementation method of this community service is carried out in three stages, namely preparation, implementation, and the final stage. The preparation stage involves coordination with the local government, situation analysis, and identification of community needs. At the implementation stage, education and training are carried out on the use of stainless steel drying tables, as well as direct practice simulations for the community. The final stage involves evaluating activities through questionnaires and interviews to measure the success of the training. The results of the community service show that the use of stainless steel drying tables improves the quality of cassia shrimp by maintaining cleanliness, reducing bacterial contamination, and extending shelf life. In addition, this training increases community knowledge about the importance of using hygienic tools in fisheries processing. In the future, it is hoped that this technology can be widely accepted by the Arar Village community to support increased productivity and more sustainable fisheries-based economic welfare.

Abstract

The Della Village Coastal Community Empowerment Program aims to increase community resilience to natural disasters through mitigation activities and evacuation infrastructure development. Implementation methods include initial survey, needs mapping, evacuation route construction, disaster mitigation training, evacuation simulations, and monitoring and evaluation. Activities were carried out participatively, involving the community, village government, and university students. Pretest results showed community knowledge on disaster mitigation was low, ranging from 25% to 40%. After training and simulation, posttest results increased significantly to 70–80%, showing improved understanding and preparedness. Beyond increasing knowledge, the activity encouraged collective awareness, social responsibility, and practical skills in dealing with emergencies. The evacuation infrastructure strengthened the village's physical readiness for potential earthquakes and tsunamis. The program proved the effectiveness of educational and participatory approaches in building disaster-resilient communities in remote coastal areas. Overall, the activity helped strengthen adaptive capacity and sustainability of community-based mitigation in Della Village

Abstract

This study aims to evaluate the effect of adding sago fiber as an environmentally friendly additive on the physical properties of mortar, namely density, porosity, water absorption, and compressive strength. The study was conducted experimentally in the laboratory with variations of normal mortar and the addition of sago fiber of 2%, 4%, and 10%. Cubic test specimens measuring 5 × 5 × 5 cm were tested at the age of 28 days for density, porosity, water absorption, humidity and temperature, and compressive strength. The test results showed that the addition of sago fiber caused a decrease in the value of the density and compressive strength of the mortar, while the porosity and water absorption values increased. The highest density value was obtained in normal mortar at 2.09 gr/cm³ and a compressive strength of 21.33 MPa. Meanwhile, with a variation of 10% sago fiber, the density decreased to 1.53 gr/cm³ and the compressive strength only reached 3.22 MPa. Environmental conditions such as temperature and humidity also affect the compressive strength of mortar. This study concluded that sago fiber can be used as an environmentally friendly additive in mortar, but its use should be limited to maintain the material's structural performance.

Abstract

The development times have been accompanied by an extremely quick development, which brought architectural features like geometric imperfections and soft store buildings. Buildings having high earthquake risk in Sorong have challenges due to an active fault.. This study's goal was to identify the relationship between displacement and drift ratio and structural performance in high-rise structures with and without set backs. Using structural analysis software, the building was modeled in this study with a maximum of 7 stories and a total height of 37 m. Seismic forces were also analyzed using reflection spectroscopy of various responses. Buildings with soft storey effects without set backs and buildings with soft storey effects with set backs are the two types under study. According to the research, soft store buildings with set backs produce the highest displacement and drift ratio outcomes when compared to soft store buildings without set backs. Based on the service limits' performance under earthquake loads, it is still within safe bounds.

Abstract

The demand for eco-friendly, economical, and high-performance building materials continues to grow, encouraging innovation in the use of blended cement. Fly ash, a by-product of coal combustion, offers a sustainable alternative as a supplementary cementitious material. This study evaluates the mechanical performance of mortar containing fly ash in blended cement, with compressive strength tested at 7, 28, and 90 days. Fly ash proportions of 0%, 10%, 20%, 30%, and 40% by cement weight were examined. Results showed that mortar with fly ash (FA-10%) achieved the highest compressive strength at 90 days. Although the elastic modulus decreased with higher fly ash content, both compressive strength and elastic modulus increased over the curing period. The Poisson’s ratio values ranged from 0.1 to 0.3, indicating the material remains within the classification of normal solid materials. These findings suggest that incorporating fly ash can improve the sustainability of construction materials without significantly compromising long-term mechanical performance. Fly ash can therefore be considered an effective partial replacement for cement in efforts to develop more environmentally responsible and sustainable building solutions.
