Abstract

Turning is a metal cutting process that changes the geometry of a material. In this turning process there is a response to be obtained, namely the lowest shaft surface roughness value. Therefore, it is necessary to set the right process variables in order to produce the best roughness value. In this study using the Response Surface Methodology, namely Box-Behnken Design. The purpose of this study was to determine the right combination of levels from the combination of variables in the CNC lathe machining process on VCN 150 material so as to optimize the roughness value. Variables that are thought to have an effect on the surface roughness of VCN 150 material are cutting speed with levels (120 m/minute, 140 m/minute and 160 m/minute), feeding speed with levels (0.14 mm/turn, 0.21 mm/minute). revolutions and 0.28 mm/rev) and depthof cut with levels (0.5 mm, 0.75 mm and 1 mm). The surface roughness value with the lowest value with each variable is the cutting speed of 120 m/min (level 1), the depth of cut is 0.75 mm (level 2), and the feeding speed is 0.28 mm/minute (level 3) the roughness value is 0.468 m.

Abstract

The development of processed products from ginger has recently begun to grow, especially with the presence of the Covid 19 virus which has an impact on all countries, especially for Indonesia. Preparations made from ginger and other spices are believed to maintain stamina for the human body. Processed products from ginger ranging from ginger wedang, ginger candy and instant ginger. Some of the benefits of instant ginger for health include warming the body, relieving colds, reducing menstrual pain and many other uses. Some types of ginger that are commonly developed in Indonesia include red ginger, small and large white ginger. With the different characteristics and benefits of each type of ginger, the ginger that is often processed into powdered ginger or instant ginger is red ginger. In Bangka Belitung, especially Bangka district, Mrs. Salimah has been processing this instant ginger since3 years ago, until now she is still producing this red ginger instant drink. The problem faced by Mrs. Salamah as a community service partner is because the equipment used to produce instant ginger still uses manual or makeshift equipment so that the resulting production is not optimal. To cover the lack of partners' problems, community service will provide solutions to partners, namely in the form of TTG machines (appropriate technology) to support instant ginger production. By using this squeezer machine, Mrs. Salimah can extort 5 kg in 15 minutes compared to using her hands, 5 kg can take 30 minutes.

Abstract

Red brick is a very important building material in building construction. Red brick has a rectangular physical shape with a distinctive color, namely red. Red bricks are made of clay mixed with sand and water, then mixed evenly and molded as desired. According to the quality standards, red brick is said to be of good quality and quality if it has several criteria including having the required size, compressive strength, and water absorption capacity. This research was conducted to see the effect of the length of drying time after printing, the effect of heating time, heating temperature, and the surface topography of red brick. The data processing method uses the Response Surface (RSM) method using Design Expert 09 software. The results show the smallest compressive test value of 131.4 kg/cm2. The biggest value is 148 kg/cm2. The most significant influence on the red brick making process is the drying time. The longer the drying process will cause the water content in the red brick to decrease. The SEM results show that the effect of drying red bricks that experience longer drying will coalesce and crystallize more easily. Based on the analysis of the results of the study that a longer drying time will cause an increase in compressive strength.

Abstract

One source of natural fiber whose utilization still needs to be developed is fiber from corn husk which is cheap, abundant and environmentally friendly. The increasing production of corn plants causes an increase in corn husk waste which is also higher. Even though this corn husk has very strong fiber and can be used as a composite of natural fibers. Composites reinforced with natural fibers have excellent corrosion resistance properties, as well as lower production costs, are more abundant and are considered to be more environmentally friendly. The aim of the study was to determine the effect of soaking 7% NaOH for 1 hour, 2 hours and 3 hours and the effect of curing time at temperatures of 95°, 105° and 115° for 4 hours on the tensile strength of the corn husk fiber woven composite and to determine whether corn husk woven fiber composite can be applied as a car bumper manufacture. Making samples using the hand lay-up method. The analysis was performed using the factorial method. The highest results were found in the tensile test specimens using a variation of NaOH immersion time for 2 hours at a temperature of 95°C having a tensile test strength of 19.93 MPa. Meanwhile, the lowest tensile test strength value was 12.13 MPa using a variation of NaOH immersion time for 3 hours with a temperature of 115°C. Based on the standard for making car bumpers, the corn husk woven fiber composite can be applied as an alternative material for making car bumpers.

Abstract

The development of composite materials currently not only with synthetic reinforcing materials but also with natural fiber reinforcing materials, because natural fibers have diverse characteristics. In this research, looking at the characteristics of Oil Palm Empety Fruit Bunch (OPEFB) fiber which has a high cellulose and hemicellulose content, which is generally used for soundproofing materials. So a composite research will be made from the main material of OPEFB  fiber with polyester resin as the matrix. The purpose of this research is to determine the sound absorption value of the composition of the mixture of OPEFB  fiber and resin. The method used is the hand lay-up method combined with the Taguchi Method on the L4(23) orthogonal matrix design used as a reference for the sound absorbing composite manufacturing process. The L4(23) orthogonal matrix design is used because there are three process parameters that have two levels. Repetition is repeated three times. The process parameters are the volume fraction of OPEFB  fiber and resin, the length of fiber soaking with NaOH, and the thickness of the composite. The research results from three repetitions obtained the highest value in sample I with a mean value = 77.93 dB at a frequency of 2000 Hz, and the lowest value in sample III with a mean value = 32.97 dB at a frequency of 125 Hz.
