Helen Rindy Affikasari — 2022-12-14

Kupang is a food that comes from the sea which contains various health benefits. Kupang is a type of shellfish that lives in the sea. This type of shellfish has a fairly high nutritional content, but unfortunately not everyone knows the content contained in mussels. And sometimes it's just made into processed food with soup without any innovation. The obstacle experienced by the seller of the village of Balnggabus is that the customer must come directly to the location to get the desired Kupang. Another problem faced is that customers are often disappointed because the supply of mussels has run out or when the seller is not selling. With a web-based sales information system, Kupang sales can reach a wider range of consumers and make it easier for consumers to make transactions.

Indonesia is one of the tropical countries where there are many entrepreneurs engaged in chili farming found in rural areas. Chili is a commodity plant that is in great demand throughout the world and in Indonesia, therefore without good processing or preservation, the quality of chili quickly rots and the price drops in the market. In the chili processing process, it is very dependent on sunlight, but due to the uncertain climate and drying using sunlight, it needs a long and unhygienic process, causing the chili processing process to be hampered. For this reason, the design of a drying system that utilizes heat from burning charcoal is specifically designed to speed up the drying process. This chili drying system utilizes heat from burning charcoal in the furnace and flows hot air into the system with the help of a blower whose speed is varied, namely 6000 Rpm, 4000 Rpm and 2000 Rpm, with variations in the testing capacity scale to determine the tamping power on an efficient rack when this dryer works. After testing the tool, it is known that in a drying time of 30 minutes, the variation is more effective with an even distribution of heat in the system with a maximum blower speed of 100 grams with a drying rate of 20% to 30%.

Heat treatment carried out on steel materials will have an effect on the hardness and changes in metal structure in iron or steel. The addition of this hardness depends on the type of steel material used, temperature, and the cooling medium used such as oil, air, and water. In this study, the hardness of the iron cutting knife was increased through a heat treatment process to determine the effect of the hardness of the cutting knife on the result of cutting a 2 mm iron plate. The test object is a cutting knife which will be heated to a temperature of 850°C, cooled using SAE 35 oil. The test results show that the harder the cutting knife, the smaller the angle of inclination of the 2 mm plate..

The Effect of Fiber Volume Fraction on the Bending Strength of Fiber-Reinforced Composites of Oil Palm Empty Fruit Bunches

Rizky Gunawan — 2023-03-14

In this modern era, the palm oil industry is growing, so the waste is also increasing. If the waste from the palm oil industry is not processed, it will pollute the environment. One way to process palm oil waste is to turn the empty palm fruit bunches (OPEFB) fibers into composite reinforcement. Various natural fibers can be applied to become composite reinforcement, so it is necessary to study the character of OPEFB fibers for composite reinforcement. This study will look at the effect of various volume fractions on the bending strength of the composite. The volume fraction consists of 20%, 30%, and 40% fiber. The composite is then tested for bending to determine the bending strength of the composite. The results of the tests showed that the highest bending strength value was the 30% volume fractional variation with 47.70 MPa. The 40% volume fraction variation has the lowest bending strength value of 29.53 MPa.
