Jurnal Ecocentrism adalah sebuah wadah yang memuat artikel-artikel lingkungan dari para akademisi, praktisi, dan penggiat lingkungan. Istilah Ecocentrism diambil dari sebuah teori etika lingkungan yang lebih luas. Semoga jurnal ini dapat dijadikan pedoman dan solusi dalam menjaga keseimbangan alam di Indonesia bahkan dunia.

Abstract

Fatumonas Village is located in Amfoang Tengah Sub-district, Kupang Regency, East Nusa Tenggara Province, which has an area of 32.76 Km² and has a population of 2119 people in 2022. There are 7 spring locations, but there are several spring locations that are not located near settlements, making it difficult for people to reach and obtain clean water. The need for clean water is calculated based on population projections analyzed using the geometric method. Spring planning in the form of transmission and distribution pipeline maps planned 2 springs namely Haukauna Spring, Oelpel Spring is done by pump and gravity.

Abstract

There is a lot of excavation of materials for concrete mixtures in nature so that their existence is dwindling. Efforts are needed to find substitute materials but still maintain the quality of the concrete obtained. The purpose of this study is to determine the percentage of waste lava stone as a substitute for coarse aggregate in order to obtain compressive strength according to the plan and to determine the effect of environmental sustainability after waste stone is used as a concrete mixture. This study was conducted at the Laboratory of the Faculty of Engineering Unmas Denpasar by making a cylindrical specimen with a diameter of 15 cm and a height of 30 cm. Replacement of lava rock waste was made in 5 categories P0, P1, P2, P3, P4 with 8 specimens in each category, where the compressive strength test was carried out at the age of 28 days, with category P0 as a control without adding lava rock waste. The results showed that there was an increase in the compressive strength of concrete in categories P1 and P2, P3 and a decrease in the compressive strength of concrete in category P4, but the decrease that occurred design compressive strength.

Abstract

With the rapid development at this time, the need for building materials continues to increase, especially concrete-forming aggregates. In this study, ceramic shards were used as an ingredient in the concrete mixture and compared with concrete in the same mixture composition. The research was conducted in the laboratory on the constituent materials in the concrete mix, namely cement, sand and crushed stone. To find out whether the alternative material, namely ceramic shards, meets the requirements, a test is carried out, namely through a concrete compressive strength test. The compressive strength test was carried out by making a mixture of normal concrete and concrete mixed with ceramic shards starting at a proportion of 10%, 20%, 30% and 40%. In this study, a cube test object measuring 15 x 15 x 15 cm was used. The mixed concrete mix was prepared in 8 trials for each proportion and the compressive strength test was carried out at 14 days and 28 days of age. The results of the research showed that the ceramic shards fulfill the requirements as aggregates in the concrete mix, according to the compressive strength value of the resulting concrete. namely concrete K225.
