Abstract

This study aims to predict corrosion in water distribution pipes at the Bukit Indah Unimal campus. Corrosion is the damage to chemical elements in a metal that changes the original properties of the metal. There are four kinds of processes for corrosion, namely, one anode loses electrons, two cathodes accept electrons, three liquids and four metals connect the cathode and anode. The geoelectric resistivity method is used to determine the soil resistance properties of the subsurface layer. The wenner 4 pin method is a geoelectric data retrieval that is often used with the same pin spacing arrangement. Res2Dinv is software that is on a computer to generate 2-dimensional images from the resistivity data obtained and determine the layer below the surface. From the inverse results, the smallest error value can be obtained when iterating up to 4 times, namely Java Road 45.3%, Sulawesi Road 49.6%, Kalimantan Road 30.6%, Sumatra II Road 46.1%, Main Gate 41.1% Sumatra I 23.4%. Based on the data, the measurable results below the surface range from 0.05 m to 5 m.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui kekuatan bending yang paling optimal dari komposit serbuk kayu dengan variasi fraksi berat serbuk 10% Serbuk Kayu + 90% Resin BQTN 157, 20% serbuk kayu+80% resin BQTN 157 dan 30% serbuk kayu+70% Resin BQTN 157. Untuk Proses pembuatan spesimen uji dengan bahan serbuk kayu dan resin polyester sesuai dengan standar ASTM D790. Komposisi 10%:90% dengan hasil rata-rata 37,814 Kgf untuk beban maksimum dan 0,376 Kgf/mm² untuk kekuatan tekan. Nilai kerapatan tertinggi pada material berkomposisi 10% serbuk kayu semaram dan 90% resin adalah  1,193 gr/cm3. Sedangkan untuk komposisi 20% serbuk kayu semaram dan 80% resin hasil yang didapat 1,046 gr/cm3. Dan untuk komposisi 30% serbuk kayu semaram dan 70% resin hasil yang didapat 1,095 gr/cm3. Proses pencampuran yang terbaik terjadi pada specimen dengan komposisi 10% serbuk kayu dan 90% resin. Jenis patahan yang terjadi berupa getas
