Abstract

Fiber Reinforced Polymer (FRP) is an alternative for planning, repairing, and strengthening structures. FRP is a combination of fiber as reinforcement and resin as adhesive. Reinforcing materials can be made of carbon, aramid, glass, and natural fibers. Utilization of Natural Fiber Reinforced Polymer (NFRP) FRP with natural fibers can be more economical. The natural fiber used in this research is abaca fiber which is often found and is not used for structural reinforcement. The purpose of this study was to determine the increase in shear strength of reinforced concrete beams with different widths of NFRP abaca fiber. NFRP Abaca fiber is fully wrapped (complete wrapping) on the surface of the reinforced concrete beam. The study was conducted on four reinforced concrete beams measuring 15 cm x 30 cm x 220 cm with simple support with two load points to determine the effect of abaca fiber width on increasing the shear strength of the beam. One specimen as a control test object and three specimens reinforced with Abaca Fiber NFRP with variations in fiber width of 2.5 cm, 5 cm, and 7.5 cm, respectively. The test results show an increase in the shear capacity of reinforced concrete beams as the fiber width increases. The flexural failure occurred in the test object with a width of 7.5 cm, this was the case that the shear capacity of the beam had exceeded the flexural capacity of the beam.

Abstract

The major cause of early failure in the infrastructures of the palm oil industry in Aceh, Indonesia has been discovered to be the corrosion caused by air pollution from exhaust fumes of the factory plants. Therefore, this research was conducted to analyze the effect of the atmospheric corrosion of the structural steel used in the palm oil mill industry. The five types of structural steel used as samples include strip, l-shape, round bar, plate, and SAPH 610 low carbon steel with a carbon content of 0.18%. These specimens were cleansed from dirt, scaled, and rubbed with sandpaper to achieve a grid of 600, later washed with fresh water and rinsed with alcohol, and subsequently exposed to the environment in PT ASN and PT AKTS palm oil mills for 12 months. Moreover, they were placed on a measuring tray for exposure and the corrosion rate was recorded once a month using the mass loss method in line with the ASTM G50. The results showed the steel construction with a round bar shape was more resistant to atmospheric corrosion and the remaining samples were also observed to be safe and relatively resistant based on their classification as being outstanding (< 1 mpy).

Abstract

The people of Aceh are known as coffee lovers. One of the advantages of serving Aceh coffee is the traditional blend process using human labor. Aceh coffee brewing is made manually brewing 5-7 times. This brewing process is believed to affect the quality of taste offered, where the higher the filter is removed, the better the quality of the coffee will be. It is known that workers at Zakir Coffee Shop can make an average of 270-320 Aceh filter coffee cups a day. Work posture in this process is carried out with 4-5 repetitions with a load of 3 kg by standing position. The data in the study were taken from 5 Zakir Aceh coffee shops with 10 respondents. The method used is the Rapid Upper Limb Assessment, that used to assess work posture and investigate disorders of the upper limbs. The second is the Nordic Body Map (NBM), to find out the parts of the muscles that are experiencing complaints. The research aids used are roll meter, digital camera, and stopwatch. The result of this research is an analysis of 3 work postures where work posture 1 is on the action scale 4 for the right and left limbs, work postures 2 and 3 are on the action scale 3 and 4 for the right and left limbs. The suggestion proposed to reduce worker complaints is to design a tool that can perform movements such as the required work posture. The main dimensions of the tools that are planned are based on the dimensions of the workers' bodies used in the coffee brewing process, 9.6 cm palms and 11.6 cm soles.
