Abstract

The purpose of this study was to analyze the break-even point or to find out a favorable point in using a concrete casting tool, between modern equipment and innovative equipment in small islands and coastal areas. This research method is to analyze by using break-even analysis on concrete casting work by using modern equipment and equipment invasion by researchers on small islands and coastal areas based on Appropriate Technology. The conclusion obtained from the concrete mixing work using modern equipment and equipment innovated by researchers on small islands and coastal areas is that the use of modern equipment is very efficient if the volume of concrete is more than 5,559.19 m³ and very inefficient if the volume of concrete is less than 5,559.19 m³. Meanwhile, the use of innovative equipment is very efficient if the volume of concrete is less than 5,559.19 m³ and very inefficient if the volume of concrete is more than 5,559.19 m³. Specifically for equipment invaded by researchers, apart from being able to lift fresh concrete according to the analysis, another advantage is that it can still lift all types of materials that will be needed in a project, another advantage is that it is based on Appropriate Technology and is easy to mobilize and demobilize to small islands and coastal areas.
