Abstract

Various types of trees grow in Indonesia, one of which is the Nyatoh tree. Uses: This nyatoh wood tree is very useful as a material for building houses, making furniture, and so on. In the process of processing nyatoh trees into finished materials, shavings or powder will be produced, but the use of shavings or powder has not been utilized optimally. So the rest of the process makes the surrounding environment dirty and unsightly. This composite material has the advantages of adjustable strength, excellent fatigue strength, corrosion resistance, light weight and very low production costs. The aim of this research is to determine the tensile test value of nyatoh wood powder composites at volume fractions of 5%, 10%, 15% with a mesh size factor of 100, 150, 200 and a curing time of 2 hours with a heating temperature of 60 ?, 80 ?, 100 ?. The research method used is the full factorial method. The composite material is made using the hand-lay-up method. The highest tensile strength value in this research was a 5% sample with a mesh size of 200 and a curing time temperature of 60 ? with a tensile test result of 30.60 Mpa. Meanwhile, the lowest tensile strength result was 10.97 Mpa at a powder fraction of 5% with a mesh size of 100 and a curing time with a temperature of 60 ?. The size of the mesh greatly influences the tensile testing, where the higher the mesh used, the tensile strength increases. Meanwhile the heating process (curring time) also has an influence, but not so big, the higher the temperature of the curing time will cause a decrease in tensile strength.

Abstract

One of the superior programs for agriculture, plantations and food crops through the 3S slogan, namely Sahang (pepper), cows and rice fields, which has been established by the Bangka Belitung Islands Provincial Government, and cows are a source of animal protein that people consume every day. The need for beef will increase at certain moments, for example the celebration of Eid al-Fitr, Eid al-Adha or other major holidays. Another superior plantation product that is the focus of plantation farmers in Bangka Belitung is oil palm. From these two agricultural commodities, integration of cattle farming and oil palm plantations can be developed with the aim of getting benefits in the form of cross-utilization of waste from oil palm plantations as additional green feed and manure waste. from cattle farms as organic fertilizer, with the hope of efficiency and mutual benefit. However, there are separate problems for small-scale livestock groups in implementing this program, because to utilize agricultural waste in the form of palm fronds requires a chopping process so that it can be used as a replacement feed source for green food, if done manually it will certainly not be able to meet needs. this feed, and this is an obstacle faced by the Towards Prosperity Farmers Group partners on Jalan Belinyu Silip, Riau Silip sub-district, Bangka Regency. From the problems mentioned above, it can be concluded that appropriate technology is needed to help the process of chopping oil palm fronds into cattle feed products, making it easier to provide cattle feed every day, and it is hoped that this solution can increase the number and income of cattle breeders.

Abstract

Brake lining components that contain asbestos are dangerous for human health, so innovation materials environmentally friendly is needed. This research aims to determine the effect of volume fraction and sintering temperature to density and hardness of recycled aluminum matrix composites, reinforced with silicon carbide and rice husk ash using the powder metallurgy method, with varying reinforcement volume fractions 10%, 15%, and 20%. The powder mixing process uses a mechanical alloying method, while the hot compaction process uses a two-way pressing method with a hydraulic pump machine compaction pressure of 6000 PSi. The sintering temperature was varied at 550°C, 580°C, 610°C. Density testing refers to Archimedes' law with the ASTM B 962-17 standard, while hardness testing uses Portable Brinel with the ASTM E110-14 standard. The density and hardness test results show that the value increases with the amount of matrix used. For samples volume fraction 90%, the highest density value is 1.72 g/cm3 and the highest hardness value is 40HB. Based on microstructural analysis, this condition occurs because the relatively low duration of the powder mechanical alloying process has resulted in agglomeration of the reinforcing powder, and the impact interlocking bond becomes lower with increasing reinforcing powder used.

Abstract

The compaction method of powder metallurgy technology is an important process in influencing the density and hardness of the resulting product. This study aims to determine the effect of a one-way compaction method compared to a two-way compaction method on the density and hardness of the resulting composite product. The experimental method for making aluminum matrix composites with silica sand reinforcement applies a compaction pressure of 4500 Psi. Mixing utilizing mechanical alloying used a horizontal ball mill machine. The density test refers to the Archimedes principle with the ASTM B962-17 standard, while the Rockwell Brinel hardness test uses the ASTM E110-14 standard. The results of the sample density test of the two-way compaction method of compaction showed a higher value compared to the sample density of the one-way compaction results, respectively; values of 2.132 g/cm3 and 2.119 g/cm3. The hardness value of the sample resulting from two-way compression compaction also has a higher value than the sample hardness resulting from one-way compression compaction, respectively; worth 43.67 HRB and 36.78 HRB. Furthermore, based on the results of microstructural analysis, the interlocking bonding occurs in composite samples with two-way compaction. It is also better than the interlocking mechanical bonding in composite samples resulting from one-way compaction.

Abstract

In vehicles, it is very important for driving safety, therefore a reliable and optimal braking system is needed. This research focuses on reducing the use of asbestos by replacing it with more environmentally friendly materials. In addition, this study also aims to determine the effect of differences in material composition variations and sintering temperatures on the density value and hardness test of the composites produced. The method used to make composites from aluminum is the powder metallurgy method, with the stages of the process of preparing tools and materials, mixing powders, compassing, and sintering. The mixing of aluminum powder, silica sand, rice husk ash and bagasse ash uses a horizontal ball mill machine and uses the parameters of Ball Powder Weight Ratio (BPR) 10:1, machine rotation speed of 90 rpm and milling time of 4 hours. Meanwhile, the heat compaction process uses a two-way method of pressing with a hydraulic pump machine with a pressure reader. The hot composting process is carried out with a temperature of 350°C held for 20 minutes and the pressure variation of the two-way compression used is 600Psi. The results of the density and hardness tests show that the value is increasing with the number of matrices used. The sample with a reinforcement percentage of 12%, the highest density value was 2.498 g/cm3 and the highest hardness value was 73.66 HB.

Abstract

The use of asbestos in the production of brake pads is known to pose health risks, necessitating environmentally friendly innovations. This study aims to evaluate the effects of the percentage of reinforcement and hot compaction pressure on the density and hardness properties. Composites were produced using the powder metallurgy method, which involves grinding recycled aluminum powder, silica sand, and boiler fly ash with a ball mill. The process parameters used were a Ball Powder Weight Ratio (BPR) of 10:1, a rotation speed of 90 rpm, and a grinding time of 6 hours, with varying reinforcement percentages of 8%, 12%, and 16%. The compaction process was performed using bidirectional pressing with varying pressures of 5000, 5400, and 5800 PSI at a temperature of 350°C, with a holding time of 10 minutes. The sintering process was conducted at a temperature of 600°C with a holding time of 10 minutes. Testing was carried out using density tests in accordance with ASTM B962-17 and portable Brinell hardness tests in accordance with ASTM E110-14. The test results showed that an increase in the percentage of reinforcement and hot compaction pressure improved the density and hardness of the composite. The highest density obtained was 2.262 g/cm³, while the highest hardness reached 49.2 HB at a reinforcement percentage of 16% with a compaction pressure of 5800 PSI.
