    Abstract

    The purpose of this study was to: (1) Knowing the effect of variation in types of bentonite on the permeability on the in green sand molding sand. (2) Knowing the effect of variation in types of bentonite on the strength to press on the green sand molding sand. The study was conducted at the Laboratory of the Polytechnic Manufacturing Ceper Klaten by using the main ingredient in the form of silica sand, bentonite and water. Sample of the study is a green sand molding sand mixture having the composition of silica sand - water with different types of bentonite (Bent-A Ultra, Ultra Bent-B, and BK). Sand mold is made by manual, the standard composition of 1000 grams of sand: 9% bentonite: 4.5% water. Specimen testing performed 2 times the level of permeability testing using Tester permeability and compressive strength testing using a Universal Sand Strength Machine. Techniques used in data analysis is descriptive of data. The results of this study were: (1) The effect of variation in types of bentonite on the permeability on the in green sand molding sand. (2) The effect of variation in types of bentonite on the strength to press on the green sand molding sand. Key words: green sand molding, types of bentonite, level of permeability, power to press
