Abstract:

This study illustrates how the mechanical characteristics of a composite may be altered by adding powdered natural fillers such as fish scales or coconut shells. Hand lay-up approach has been used to create the Jute/Basalt hybrid composite with fillers. The epoxy and hardener were combined at a weight ratio of 10:1, and then the natural fillers were added at varied percentages of 3%, 6%, and 9%. The ASTM standards were used for the mechanical test. Fish scale filler has greater tensile and flexural strengths than coconut shell powder, but the latter's impact strength grows with increasing amou

Abstract:

Indonesia's natural products are very rich, including containing several types of animals, one of which is a clam that belongs to one type of shellfish. Mussel shells contain 39.55% calcium carbonate (CaCO3). The presence of calcium carbonate in the shell makes it possible to use it as a source of catalyst in the carburization process. Carburization adds carbon to the steel when heated to austenitic temperatures, causing the carbon to diffuse onto the steel surface. Low carbon steels with a carbon content of less than 0.3% are usually used in this process. Among the low-carbon steels widely us

Abstract:

In this study, we prepared activated carbon from coconut shell with a low activating time for activated carbon (AC). The coconut shell powder (< 100 µm) allows for an effective pyrolysis process and low activation time (30 min) that reduces the cost of production. The AC has characteristics of micropore with average size of 1.9 nm and a surface area of 460.50 m2/g. For supercapacitor electrode, the AC electrodes have capacitance of 50, 66, and 67.5 F/g when 0.5 M, 1 M, and 2 M of Na2SO4 electrolyte was being inserted, respectively.

The use of waste eggshell powder and coconut shell ash as a partial substitute for cement in the manufacturing of paving blocks is a solution to reduce waste and greenhouse gas (CO2) emissions during the cement production process.

Many methods can be used by the community to burn coconut shells into charcoal, one of which is by utilizing appropriate technology fueled by diesel oil, namely shell powder processing machines. The production of briquettes from coconut shells is still limited and has not developed rapidly because the process of shelling coconut shells is still simple thus it takes three to five days. The use of adhesive amounts is not optimal. This is done to fulfill the community's desire; therefore, coconut shell waste can be managed as raw material for making briquettes to become a source of community inco
