Abstract

Indonesia is a country rich in natural resources, particularly coal and coconuts. The purpose of this research is to determine the effect of drying processes and the addition of coconut shell biomass to anthracite briquettes on volatile matter content and ash content. A full factorial method was employed in this study, with three factors: drying temperature, drying time, and water-to-molasses ratio. The results show that the coconut shell biomass added to anthracite briquettes significantly affects the volatile matter content. The lowest volatile matter content, 24.8%, was observed in briquette samples dried at 120? for 90 minutes with a water-to-molasses ratio of 4:3. On the other hand, the highest volatile matter content, 28.1%, was produced by briquette samples dried at 100? for 90 minutes with a water-to-molasses ratio of 4:1. The lowest ash content, 41.1%, was found in briquette samples dried at 120? for 60 minutes with a binder ratio of 4:1, while the highest ash content, 35.8%, was observed in samples dried at 100? for 60 minutes with a binder ratio of 4:3.

Abstract

In order to satisfy the wants and desires of human life, science and technology have advanced quickly. Science and technology are developing in many facets of life. Technological advancements also happen in composite materials, which are still being studied today. Particleboard is a manufactured board created by pressing industrial waste from plantations, forestry, and agriculture together with organic adhesives. Low-quality wood waste products that may contain cellulose and lignin, such as sawdust, twigs, lathing residue, and others, can be used. The PVAc polymer was subjected to temperatures of 90°C, 100°C, and 110°C in this work, which employed a direct experimental method. The parameters used were mesh 10, 20, and 30 with a volume fraction of 60%: 40%, 70%: 30%, and 80%: 20%. In this study, the results of the largest impact strength were found in the volume fraction of 60%:40% on mesh 30 with heating at 90°C for 15 minutes amounting to 16.34 J/m2, and the smallest impact value was found in the volume fraction of 70%:30% on mesh 10 with heating at 100°C amounting to 9.28 J/m2, where these values do not meet the SNI-03-2105-2006 standard for making particle boards.

Abstract

The use of metal materials in the industrial world is increasingly widespread, so that over time metals are becoming increasingly difficult to obtain and people are required to think critically so they can look for alternative materials from the limitations of metals that are easily available and abundant, one of which is composite materials. Composite is a combination of two or more materials with different ingredients. The aim of this research was to determine the effect of thatch stalk length of 50, 60, 70 mm and a volume fraction of 35% with an oven temperature of 90°C for 45 minutes, 40% with an oven temperature of 100°C for 45 minutes, and 45% with an oven temperature of 110°C for 45 minutes when soaking the thatch stalks in 4% NaOH for 2 hours for the bending test. The highest flexural strength value was at a shank length of 50 mm with a volume fraction of 35% with an oven temperature of 90°C of 48.23 MPa. This is because the shorter the thatch stalks, the denser the thatch stalk composite looks and at a volume fraction of 35% the thatch stalks and resin stick well and the oven temperature should not exceed 90°C because if it exceeds the thatch stalks it will shrink and the flexural strength will increase. small.

Abstract

This study aims to analyze the effect of dry corn husk fiber layers with a 50% volume fraction on the mechanical properties of composites made using the hand lay-up method and alkali NaOH treatment. The corn husk fibers were treated with 4% NaOH for 1, 2, and 3 hours at temperatures of 80°C, 90°C, and 100°C to produce composites with polyester resin. Tensile and bending tests were conducted according to ASTM D-638 and ASTM D-790 standards. The results showed that NaOH treatment for 3 hours at 90°C produced the highest tensile strength of 21.1 Mpa, while NaOH treatment for 1 hour at 80°C produced the highest bending strength of 53.0 Mpa. On the other hand, NaOH treatment for 2 hours at 80°C resulted in the lowest tensile strength of 5.84 Mpa, and NaOH treatment for 2 hours at 100°C resulted in the lowest bending strength of 8.53 Mpa. Longer treatment durations and higher temperatures effectively remove lignin and hemicellulose, increasing tensile strength but can damage the fiber structure for bending tests. This study demonstrates the potential of corn husk fibers as an environmentally friendly and sustainable composite material.
