Abstract

Wood waste was waste from the wood production process which can be in the form of chips or remaining pieces of wood. Based on these data, processed wood scrap waste can be used as an industrial product in the form of a children's study table, while the remaining wood waste that has been disposed of so far has been left to rot, stacked and burned, resulting in a negative impact on the environment. The problem in this research was how to make a children's study table from waste pieces of wood. The aim of the study was to make a children's study table from waste pieces of wood, while the method used was an experimental method using 2 samples with different material compositions. The result of the research was that a children's study table was made which has a length of 60 cm and a height of 25 cm. Then the conclusion of the study resulted in a children's study table product from wood scrap waste.

Abstract

The area of coconut plantations in South Aceh Regency was 6839 Ha, out of the total number of sub-districts in South Aceh. South Kluet District was the area with the largest coconut plantation area compared to other districts, reaching 1433 Ha. Coconut coir fiber was usually used for household equipment, such as floor brooms, doormats and rope. Coconut farmers rarely process coconut husks, and after harvest, they just leave the coconut husks piled up under the coconut trees until they rot. In this research, coconut fiber waste was used as reinforcing fiber for composite materials. The aim of this research was to be determined the mechanical strength of marble waste composites mixed with resin and reinforced with coconut fiber. The composition tests carried out were: 85 : 10 : 5, 80 : 10 : 10, 90 : 7.5 : 2.5, and 80 : 12.5 : 7.5. The test carried out on each test specimen composition was a tensile test. From the results of the tests carried out on the test specimens, the maximum stress was found in the composition: (85: 10: 5) 85% Resin, 10% Marble, 5% Coconut Fiber with an average maximum stress value of 29.44827586 N /m2 and the average modulus of elasticity is 0.2415123283 N/m2.

Abstract

The coconut trees were one of the commodity crops in South Aceh which were multifunctional trees because almost all parts of the coconut tree can be used. One part of the coconut tree that can be used was the coconut tree stump which can be processed into chairs. The aim of this research was to design chairs from coconut tree stumps, made chairs from coconut tree stumps and determine the ergonomic value of coconut tree stump chairs. The result of this research was the creation of a new innovative chair made from coconut tree stumps which has an overall height of 79 cm, chair back height 32.5 cm, chair back width 64 cm, seat depth 46 cm, armrest height 16 cm, and leg height 34 cm. Coconut tree stump chairs were made through several processes, namely the process of taking raw materials, the process of making chair patterns, the scraping process, the sanding and varnishing process. The coconut tree stump chair was a chair that was not ergonomic, because there were several parts of the coconut tree stump chair that did not comply with the concept of ergonomics.
