Abstract

Gayo coffee is a superior regional product in the Central Aceh district. The production process of Gayo coffee is still done traditionally. In developing the quality and quantity of Gayo coffee, it is necessary to apply the production process technology. PKM activity partner, CV. Aceh nutrition has problems in the production process, especially in the sorting process, which is still manual. This process requires labor and long processing time so that the production process becomes inefficient. This problem is essential to be resolved in an effort to increase partner productivity. This service activity aims to improve the efficiency of the coffee bean production process through the application of a green bean sorting machine. The sorting machine will produce green beans based on size or dimensions following SNI. Solving partner problems is carried out using functional and structural approaches. Activities started from problem identification, design, and fabrication of green bean sorting machines, implementation and training, assistance, and evaluation. The results of these activities, green bean coffee sorting machines have been successfully fabricated with a capacity of 200-300 kg/hour. This machine has been implemented to partners CV. Nutrisi Aceh. The green bean sorting machine implemented to partners can operate well. The resulting large green beans amount to 30-40% of the total sorted green beans. The use of a sorting machine can increase the efficiency of time and labor in the green bean sorting process so that partner productivity can increaseABSTRAK:Kopi Gayo merupakan produk unggulan daerah kabupaten Aceh Tengah.

Abstract

This study aims to determine the impact strength fiber-reinforced epoxy composites coco Composites made using a matrix of fiber-reinforced epoxy resin and coco. Coco fiber used is cleaned and dried in the sun for three days. Coco fiber is cut with every fiber length ± 3 cm, then soaked in an alkaline solution (NaOH) 2.5% for 5 hours. Composites formed with a variation of the weight of the matrix of the fiber that is 10, 20, and 30. This experiment is testing the impact. The highest impact toughness value generated on epoxy composite with the addition of coconut coir fiber as much as 30% compared to 20 and 10% variation. The greater the percentage of coco fiber, the higher the value of the impact toughness

Abstract

Blockboard  for industrial furniture is not only enough to meet mechanical properties, but also ease the  forming process. The use of nails and screw was determined in the process of forming blockboard. The purpose of this research is to study the effectiveness of using  nails and screw on blockboard that uses the core palm oil wood particles. This research is expected later on benefics to the furniture industry  in using the appropriate nails and screw to the blockboard using the core palm oil wood particles. The nails and screw with a different diameter was used in the test of blockboard. Nailers is used specifically to wood and nails concrete, with 50 mm long  and  2,5 and 3 mm diameter. The results showed the positive and negative effectiveness of using nailers on  the core. The used of screw on both surface and core of the blokboard showed the positive result. The smaller diameter nailers used  the more effective will be on the core

Abstract

Welding defects in a construction if repairs are not immediately carried out, then in the weld defect area can cause cracks that are aggravated by wider cracking and corrosion so that it can cause brittle fractures to the detriment. The problem with brittle fracture is a big problem in steel that has been welded, especially in welded joints, this brittle fracture becomes more important due to the factors of voltage concentration, inappropriate structure and defects in the weld, the purpose of this study: to find out how to use suitable electrodes for ST 37 material in the welding process, whose cooling process directly uses Oil and water (Direct Colling Process),  and to obtain optimal welding results after going through the results of welding defect examination using the Penetrant Test method, and the Maghnetic Particle Test.  From the results of the examination research conducted by the Welding Inspection team of PT. Superintending Company of Indonesia (SUCOFINDO) to 15 ST 37 specimens that have undergone welding does not show any welding defects, in the sense that they are still within the acceptable limit criteria (Acceptance Standard Ansi B 31.3), from the results of tensile testing On the use of different electrodes in the welding process of ST 37 material, shows that the ST 37 material whose welding process uses electrode E7016 welded results and tensile strength is better than the  ST 37 material which in the welding process uses electrodeS E 7018 with the cooling process using Oil and water

Abstract

Composite materials is increasingly experiencing an increa- sing trend, the manufacture of composites currently uses a lot of natural fiber reinforcement, Oil Palm Empty Fruit Bunches (OPEFB) fiber is a fiber that comes from oil palm empty fruit bunches waste that grows a lot in Indonesia and has the potential to be used as reinforcement in the manufacture of composites. With natural fiber reinforcement. The manufacture of composites in this study varied the fiber volume fraction by 5%, 15%, and 25%. Many previous studies on composite materials have focused on studying the physical and mechanical properties of composites. Even though damage to a structure or material is not only caused by static loads but also by dynamic loads. Vibration is a dynamic load experienced by material or structure, so it is necessary to determine the dynamic character of composite materials, one of the dynamic characteristics of materials is their natural frequency, the determination of the natural frequency in this study was carried out by using the finite element method in the ANSYS software. The results of the analysis in the form of tensile strength values and modulus of elasticity were obtained from tensile testing and dynamic characters in the form of natural frequencies and vibration modes were obtained from the analysis modal simulation process. From the results of the tensile test, it was found that the composite with a variation of 15% OPEFB fiber volume had the highest tensile strength and modulus of elasticity, as well as the results of the analysis modal simulation, a composite with 15% OPPEFB fiber, had the highest natural frequency value among the other two variations.
