Abstract

Concrete is a brittle and fragile construction material so it needs to be increased in strength. This study aims to increase the strength of concrete by adding natural fibers of water hyacinth to the concrete mixture. Hyacinth fibers are cut by 3-5 cm and added with variations of 0%, 0.1%, 0.2%, 0.3%, 0.4% and 0.5% of the volume of concrete. Cylindrical specimens 15 cm in diameter and 30 cm in height were tested for compressive strength and tensile strength at the age of 28 days. The test results showed that the addition of hyacinth fiber up to 0.5% increased the compressive strength of concrete up to 17.6% and tensile strength up to 71.4% compared to normal concrete without fiber. The increase in strength is due to hyacinth fibers being able to withstand micro-cracks in concrete. The more fiber added, the more microcracks are able to be prevented thereby increasing the strength of concrete. In conclusion, the natural fiber of hyacinth effectively increases the strength of concrete both in compressive and tensile capacity.

Abstract

Flooding is a serious problem that often disrupts the lives of urban communities. Increased rainfall intensity, climate change, and rapid urban development have made existing drainage systems less effective at coping with flooding. To face this challenge, this study aims to examine community empowerment efforts in drainage management as a flood mitigation strategy. This research was conducted by combining participatory approaches and field research methods. Local communities, local governments, and stakeholders are involved in planning, implementing, and evaluating empowerment programs. This program includes skills training, education on the importance of drainage maintenance, as well as the formation of community groups active in drainage maintenance. The results showed that community empowerment in drainage management has had a positive impact in reducing flood risk. Community groups involved in this program actively maintain the cleanliness and drainage function in their neighborhoods. In addition, education about climate change and rain patterns also helps people to be better prepared for extreme conditions.
