Abstract

Indonesia is a country with a high risk of natural disasters, due to its position between major tectonic plates and in the Pacific Ring of Fire. This condition makes Indonesia prone to disasters. However, the low level of student understanding of disaster response measures shows the importance of disaster education from an early age. This community service activity aims to improve the understanding and preparedness of SMKN 1 Ketapang students in facing disasters through socialization and simulation of disaster management. The activity method consists of socializing disaster material with the help of visual aids and direct simulations guided by the BPBD team. Through the stages of preparation, socialization, and simulation, students were given an in-depth understanding of the types of disasters, evacuation techniques, and the use of light fire extinguishers (APAR). The evaluation results showed a significant increase in understanding from 30% to 80% after this activity was implemented. This increase shows that disaster education involving theory and practice is effective in building students' awareness and preparedness. This program is expected to be continued regularly to build a culture of disaster preparedness among school students.

Abstract

The quality of water used in concrete mixes, especially the Total Dissolved Solids (TDS) content, is often ignored despite its significant effect on the compressive strength of concrete. Normal, sea, and swamp water have different TDS characteristics, where sea water tends to have higher TDS. This study aims to analyze the relationship between the TDS value of water and the compressive strength of concrete at 7 and 28 days and identify significant differences in the compressive strength of concrete using normal, sea, and swamp water. The method used was experimental research, with samples consisting of 3 categories of water (normal, sea, and swamp) and 3 samples per category. TDS values were measured using a TDS meter, while concrete compressive strength was tested with a digital press. The research was conducted through four stages: water sampling, concrete mix preparation, molding of test specimens, and compressive strength testing. Linear regression analysis showed that the higher the TDS value, the lower the concrete compressive strength at 7 and 28 days. In addition, the ANOVA test revealed significant differences in the compressive strength of concrete at 7 days among the three types of water. These findings indicate the importance of paying attention to water quality in concrete mixes to produce optimum quality concrete. Keyword: concrete compressive strength, sea water, swamp water, TDS.

Abstract

Concrete is a widely used construction material due to its strength and durability, but its quality is greatly influenced by its constituent materials and the environment. In West Kalimantan, people use scrap wire from building demolition as an additive in concrete, while clean water is limited, so peat water or seawater is often used as a mixer. This study aims to determine the effect of wire mesh usage and mixing water type on concrete compressive strength at 7, 14, and 28 days. Test specimens in the form of cubes were made with variations: normal concrete (clean water), concrete with peat water, concrete with seawater, and concrete with 1% wire mesh added to each type of water, and compressive strength testing was conducted using a compression testing machine. The results showed that peat-water concrete achieved the highest strength (119.50, 207.37, and 247.73 kg/cm² at 7, 14, and 28 days), seawater concrete produced the lowest (92.87, 182.27, and 225.90 kg/cm²), and the addition of 1% wire mesh increased early-age strength up to 186.57 kg/cm² at 7 days but its effect diminished at later ages. Thus, the type of mixing water plays a dominant role in concrete quality, while steel tie wire  is more effective in increasing strength during the early stages of hardening.
