Abstract

In the welding process, the swing of the electrode is very influential on the mechanical properties of the weld. The purpose of this study was to determine the hardness value in the HAZ area of ​​AISI 1045 steel due to differences in SMAW welding electrode swing. The method in this study uses experimental research methods, namely describing comparisons of treated specimens using the help of the Microsoft Excel application. The material used in this study was AISI 1045 medium carbon steel which was welded using SMAW welding with variations of zig-zag, circular and C swing electrodes with 1G position. The results of this study prove that the electrode swing has a significant effect on the hardness value. It can be seen that the test material with a circular swing pattern has a higher value than the zigzag and C swing patterns. This is shown by testing the hardness test in the HAZ area where the circular swing pattern gets average. -the highest average hardness value is 23.47 HRC. Meanwhile, the lowest average hardness value is in the C swing pattern of 20.46 HRC. Electrode swing has an influence on the hardness value. The circular swing pattern has a higher value than the zigzag and C swing patterns.

Abstract

The sprocket gears is one part of motorcycle that functions as a power transfer transmission. The service of gears can be influenced by several aspect, one of which is the hardness of sprocket gears. The hardness of the sprocket gear material can be increased by various mathod, one of which is heat treatment. This study used an experimental method with the aim of knowing the effect of bio diesel as the main cooling medium on increasing the hardness of non-original sprocket gears. The research process included carburizing and hardening processes on 2 non-original brands at temperature of 910°C and then cooled using bio diesel and water cooling media with a holding time of 30 minute and 60 minutes. The results showed that the heat treatment process could increase the hardness of brand A with a normal hardness of 104 HB resulting in the highest value in the parameter holding time of 60 minute and water cooling medium with a hardness value of 111,6 HB and brand B of normal hardness with a value of 110,8 HB producing the highest value is the holding time parameter of 60 minutes and water cooling medium with a hardness value of 115,9 HB. Based on the result obtained, water cooling medium is higher than bio diesel cooling medium.

Abstract

Utilization of fly ash (fly ash) as an additive in the formation of lightweight bricks has a positive impact from an environmental point of view. Fly ash is a very fine residue from burning coal. The fineness of fly ash grains can potentially cause air pollution. Handling of fly ash (fly ash) at this time is still limited to stockpiling on vacant land. The addition of fly ash to the lightweight brick mixture can be a good mineral additive for lightweight bricks because the fly ash contains silica, which is binding. In this study, we will identify the benefits of fly ash (fly ash) as a partial replacement material for the use of cement in lightweight bricks. The purpose of this study was to determine the effect of adding fly ash as a partial replacement for cement on the density and compressive strength of lightweight bricks. Variations in the percentage of fly ash used are 15%, 25%, and 35%. This study used six beam-shaped test samples, with each sample being replicated three times with a mold size of 100 mm x 50 mm x 50 mm. From this study, it was found that the best density value was when using 25% fly ash, which was 1482.4 kg/m3 with the highest compressive strength value of 17.7 MPa. It can be concluded that the percentage of fly ash used affects the density of lightweight bricks. The use of 25% fly ash on lightweight bricks produces lightweight bricks with maximum compressive strength.

Abstract

Nipa plant is a plant that can be found in water areas such as in swamps. Quite a lot that can be utilized from this swamp plant. Utilization of the nipa plant can be sourced from its fruit, midrib, and leaf bones [1]. In addition to the uses previously described, the nipa plant in its midrib has fiber which has been extensively researched on this fiber. Nipa midribs which have fibers can be used as reinforcement for fiber composites. This study aims to determine the effect of arrangement and volume fraction of fibers that have been determined, as well as knowing whether the use of nipa midrib fiber as a composite reinforcement material can or cannot achieve the tensile strength value of the high impact ABS plastic material on the car dashboards. The research method in this study uses factorial design with manual composite printing. The results of this study were that the highest value of the tensile strength of the nipa midrib fiber composite was found in the vertical arrangement direction with a volume fraction 15%, namely 26.43 MPa, while the lowest value is found in the direction of horizontal arrangement with a volume fraction of 15%, namely 14.07 MPa. So that the value of the nipa midrib fiber composite in the vertical arrangement direction with a volume fraction of 15% achieves the tensile strength value of the high impact ABS plastic material on the car dashboards, namely 20 – 40 MPa.
