Abstract

Gapura berasal dari bahasa Sansekerta, yaitu “Gopura“ yang berarti pintu gerbang (Singgih, 2013). Penelitian ini bertujuan untuk mengetahui pelaksanaan perbaikan gapura sebagai fasilitas yang terdapat di Desa Limau Manis, Kabupaten Deli Serdang. Hasil analisis dari penelitian menunjukkan bahwa rehabilitas gapura belum berjalan secara maksimal. Dikarenakan kekurangan anggaran dan prosedur yang tidak memadai. Proyek ini dapat menciptakan solusi yang berkelanjutan untuk peningkatan identitas desa yang kuat dan mengetahui batas dari Desa Limau Manis dengan desa lainnya. Dengan semangat bergotong royong, tim pelaksana beserta masyarakat melaksanakan pengabdian dengan merancang dan membangun gapura yang rusak untuk direnovasi.

Abstract

Concrete has now become one of the main materials in buildings that are very important to meet the needs of civil buildings. In various infrastructure buildings in the world, concrete made using portland cement is the biggest material that is most widely used compared to other materials such as steel, wood or bamboo. The concrete industry is the world's largest user of natural resources. Hardened concrete is a combined material consisting of coarse aggregate, fine aggregate, cement and admixture or additives if needed. One way is to replace one of the basic ingredients for making concrete with polymer. A polymer is a long molecule containing chains of atoms linked together through covalent bonds formed through a polymerization process in which monomer molecules react together chemically to form a linear chain or three-dimensional network of polymer chains. The type of polymer used in this test is a recycled polypropylene polymer (plastic pellet). The purpose of this study was to determine the compressive strength of concrete and to determine the slump value of concrete. The effect of adding polymer with variations of 0%, 2% and 4% with a design concrete quality of 25 MPa at the age of 7 days and 28 days. 28 days of concrete reached 25.27 MPa. After researching the effect of adding polymer to the concrete mix can increase the compressive strength of concrete because the test results reach the design quality.

Abstract

The abundant availability of bagas seashin North Sumatra open supopport unities for it suseasanenv iron mentally friendly additive incon cretemixtures. This research aims to analyse the effect of bagas seashasapartial replace ment for fine aggregate on the compressive strength hand water absorption of layered concrete for bath room sinmulti-storey buildings. Test objects were made with variation sofbagas seash of 0% (normal), 10%, and 20%, then testedat the ages of 14 and 28 days. There search results showed that at 28 days, the compressive strength of normallayered concrete and concrete with 10% bagas seash was the same, namely 33.33 MPa, where as with the 20% variation it decreased to 30.27 MPa (down 9.18%). Interms of water absorption, layered normal concrete shows the lowest value of 0.65%, while the 10% and 20% mixtures are 0.86% and 0.87% respectively. Thus, the optimum addition of bagas seashis recommended at 10% to maintains table concrete quality.
