Abstract

Tujuan penelitian ini adalah untuk mengetahui pengaruh penambahan serat bambu terhadap beton normal. Metode penelitian yang digunakan adalah jenis kuantitatif dengan eksperimen tentang penggunaan serat bambu sebagai bahan tambah pada pembuatan beton normal. Dari hasil penelitian pada ketiga kondisi dengan benda uji kubus dapat disimpulkan beton normal umur 28 hari dengan berat rata-rata 8,265 kg/m3 dengan nilai kuat tekan rata-rata yang diperoleh 27,244 Mpa. Sedangkan untuk campuran beton serat bambu 3% dengan berat rata-rata 7,991 kg/m3 dan beton serat bambu 5% dengan berat rata-rata 8,006 kg/m3 memiliki kuat tekan rata-rata sebesar 24,444 Mpa dan 22,533 Mpa. Penambahan serat bambu pada campuran beton berpengaruh pada kuat tekan beton dimana beton dengan tambahan serat bambu mengalami penurunan nilai kuat tekan, dibandingkan dengan beton normal tanpa serat bambu. Dari hasil penelitian kuat tekan beton dengan penambahan serat bambu secara keseluruhan mencapai mutu yang direncanakan. The aim of this research is to determine the effect of adding bamboo fiber to normal concrete.  The research method used is quantitative with experiments on the use of bamboo fiber as an additional material in making normal concrete.  From the results of research on the three conditions with cube test objects, it can be concluded that normal concrete is 28 days old with an average weight of 8.265 kg/m3 with an average compressive strength value of 27.244 Mpa.  Meanwhile, the 3% bamboo fiber concrete mixture with an average weight of 7.991 kg/m3 and 5% bamboo fiber concrete with an average weight of 8.006 kg/m3 have an average compressive strength of 24,444 Mpa and 22,533 Mpa.  The addition of bamboo fiber to the concrete mixture has an effect on the compressive strength of the concrete where concrete with the addition of bamboo fiber experiences a decrease in compressive strength values, compared to normal concrete without bamboo fiber.  From the research results, the compressive strength of concrete with the addition of bamboo fiber overall reached the planned quality.

Abstract

Islam teaches the importance of maintaining the balance of nature and justice in the use of resources. Currently, one of the problems caused by human negligence due to a lack of awareness in protecting the environment is health problems. Therefore, an infectious disease that has become endemic in Indonesia is Dengue Hemorrhagic Fever (DHF). Dengue fever is caused by the dengue virus, which is transmitted through the insect vector Aedes sp. One of the controls carried out to control mosquitoes as a vector of dengue disease is to use natural predators with fish as mosquito larvae eaters. The purpose of this study is to observe the feeding behaviour and predation rate of Swordfish (Xiphophorus hellerii), and Platyfish (Xiphophorus maculatus) against mosquito larvae (Aedes sp.) and the study is based on an Islamic perspective. The observation results obtained from the feeding behaviour of X. hellerii and X. maculatus fish are that they are predators that chase, catch, and directly prey on their prey. X. hellerii fish has a higher level of feeding behaviour compared to X. maculatus fish in preying on mosquito larvae (Aedes sp.). The average predation ability of X. hellerii fish against Aedes sp. instar III larvae was 24.8 fish, while X. maculatus fish was 18.4 larvae. So that the fish X. hellerii is said to have better potential as a biocontrol to control the mosquito population, which is a vector of dengue disease, in accordance with the recommendation to maintain the balance of nature in Islamic teachings.
