Abstract

Competency-based training programs are one of the solutions to overcome the Employment problems that we are currently facing at various levels of education throughout the country, this can be seen that job opportunities are often available but cannot be fulfilled due to the limited workforce who have the required skills. One way to overcome the employment problems we are facing is to carry out workforce skills training activities that are tailored to the needs of the competency-based labor market with the assumption that if they cannot fill the available job vacancies, prospective workers who have been trained can automatically open up jobs in the informal sector. The method implemented in this training is to open advertisements in the form of banners for Luwu youth who want to take part in computer operator training to register online. After the training participants have met the desired requirements, training is carried out which is trained directly by UKI Toraja Mechanical Engineering students who are carrying out the 2022 Professional KKN and are also employees who work at the Luwu Regency BLK. The results achieved in this community service activity are the Computer Operator Assistant Vocational Work Skills Implementation activity carried out at the UPT.BLK Luwu Regency Office from July 4 to August 18, 2022 with a total of 260 training hours and a training implementation time of 33 training days with 16 participants. All were declared successful and were entitled to receive a work training certificate.

Abstract

Abstract The use of clay is mostly used to make various crafts such as flower vases, jugs and also made into pottery, bricks and roof tiles. The purpose of this study is to determine the effect of the composition of the mixture of clay, alumina and starch on the porosity, density and water content of the heat insulator cylinder. The research method used is an experimental method by making material from a mixture of clay, alumina, starch as an alternative insulator material. A series of processes are carried out in making the material. Furthermore, after the material has been successfully formed, tests are carried out on the water content, porosity, and density of the material. The results showed that the best mixture of clay, alumina and starch was obtained in sample E with a composition of 20% clay, 60% alumina, and 20% starch. The water content, porosity, and density of the mixture were 9.49%; 26.97%; and 1,514.80 kg/m^3 Key words : alumina, insulator, composition, porosity, and starch

Abstract

Biomass briquette stove is a cooking tool that is still widely used by the people of the interior of South Sulawesi. Even in urban areas, it is not uncommon to find their use because of the ease of obtaining briquettes and its relatively good efficiency. This study aims to determine the best performance of a biomass stove from three types of clay material stove shapes in different configurations of geothermal variations. The three variations of the geometric shape of the stove are cylindrical, rectangular and hexagonal using biomass material from coconut shell charcoal in the shape of a honeycomb with an inner diameter of 15 mm and an outer diameter of 65 mm and a height of 45 mm. The uniqueness of this stove is the addition of a sleeve diameter of 180mm in the stove's combustion chamber as heat insulation so that the combustion process in the combustion chamber can be more perfect. The test results show that the presence of a flat surface on the stove wall will accelerate heat loss compared to the cylindrical surface. This is in line with the results which show that the highest rate of heat loss occurs in a rectangular shape, then a six-square shape, and the last is a cylindrical shape. Furthermore, it can be concluded that the cylindrical stove is the superior of the two in terms of flame temperature, ability to boil water and thermal efficiency of 798°C, 30 liters and 73.66%, respectively.

Abstract

This study investigates and analyzes the effect of brackish water immersion on the mechanical properties of woven Petung bamboo (Dendrocalamus asper) reinforced epoxy composites. The bamboo, aged 5 years and 10 feet in length, was split, woven, and soaked in brackish water with varying salinity levels (10–30%) for 2, 4, 6, and 8 weeks. The composites were fabricated using epoxy resin and dried for two weeks before testing. Mechanical properties were evaluated through tensile and bending tests, following ASTM D3039 and ASTM C393 standards, respectively. The results show that immersion significantly improves mechanical strength under specific conditions. The highest tensile strength (74.75 MPa) was achieved by a 2-layer composite soaked for 2 weeks in 10% brackish water, while a 3-layer composite soaked for 4 weeks in 20% brackish water achieved the maximum bending strength of 84.73 MPa. Compared to untreated specimens, strength increases ranged from 30% to 60%, depending on the number of layers and immersion conditions. These findings suggest that brackish water immersion acts as an effective pre-treatment method, enhancing the fiber–matrix bonding and stiffness of bamboo composites. These results suggest that pre-treatment with brackish water can significantly enhance the mechanical performance of natural fiber composites, offering low-cost, sustainable composite materials applicable in construction, furniture, and eco-friendly product development.

Abstract

Efficient thermal insulation materials are crucial in improving performance, minimizing energy consumption, and maintaining safety in various industrial applications. This study examines the impact of multiple combinations of clay, alumina, and starch on the properties of thermal insulation cylinders. Five different composite samples were prepared by adjusting the percentages of clay and alumina while maintaining a consistent starch content. The samples were subjected to comprehensive tests to assess their water content, density, and porosity. Based on the findings, it was observed that as the alumina content increased, the water content and density of the composite materials decreased while their porosity increased. The sample labeled C6-A2 had the highest water content (9.19%) and density (1,087.04 kg/m³), while the sample labeled C2-A6 had the lowest water content (8.69%) and density (1,069.93 kg/m³). The range of porosity values observed was between 25.67% and 26.60%. It was observed that an increase in alumina content resulted in a corresponding increase in porosity. The findings indicate that the larger particle size and lower cohesion of alumina result in a more porous microstructure, affecting the material's overall properties. This study offers valuable insights into the composition optimization of clay, alumina, and starch to create customized composite materials suitable for various industrial applications. It focuses on achieving a delicate balance between water resistance, structural integrity, and thermal insulation
