Abstract

Cassava is a multipurpose plant. Apart from being used as a daily snack, cassava is also used as raw material for various industries. Currently, cassava processing technology has varied. One of them is a grating machine. The grating machine is used in order to make cassava into cassava pulp. In this research, the design of a cassava grater machine will be carried out. The design that is carried out focuses on the pulling system in the grated process. The design method used is VDI 2221. The stages in VDI 2221 are clarification of the task, conceptual design, embodiment concept, detailed design. Based on the results of the design carried out, several conclusions can be drawn, namely the chosen concept uses three towing rollers, a gear and a sprocket as a transmission roller pulling motion, while the gap control system uses bolts as the regulator. In addition, after carrying out the loading analysis on the shaft to be used as a towing roll, a roller with a size of Ø20mm can be used because the loading simulation results show that the maximum torsional stress value that occurs is 4.601 N / mm2 which is still much smaller than the value of the permitted torsional stress.

Abstract

This Community Service activity in the business of making peanut crackers in MSME "SURTAM" aims to improve one of the existing production stages, namely the manufacture of coconut milk. The process of making coconut milk carried out by partners is still traditional which causes the energy used to be quite large and takes a long time. This causes the production of peanut brittle has not been maximized. The method used to solve production problems is to design and manufacture a coconut milk squeezer machine. After that, partners are given training on how to use and maintain the machine in order to carry out maximum production. The benefit of this activity is the synergy between universities and local industries related to the application of appropriate technology that can be used directly by MSME actors in their production activities. There is an increase in the production capacity of partners, especially at the stage of making coconut milk, where before community service activities, the time needed by partners to squeeze the grated 6 coconuts for approximately 1 hour, and after the activity becomes approximately 15 minutes. In addition, partners already have the knowledge and skills in operating and caring for coconut milk extortion machines used in the peanut butter production process.

Abstract

Cigarette filter waste is something that we often find thrown carelessly in public places almost all over the world. Cigarette filters contain cellulose acetate, which is difficult to decompose naturally and takes a long time to decompose. In response to this, research is needed so that cigarette filter waste has use value and is useful as an effort to handle waste. One of them is by making cigarette butts as an alternative material made from composites. The purpose of this study was to determine the effect of variations in cigarette filter waste fibers on the tensile and impact strength of the polyester matrix. The fiber volume fraction includes 15% : 85%, 22.5% : 77.5%, 30% : 70% with horizontal, vertical and cross fiber directions. The material used is cigarette filter waste fiber. Standard ASTM D-638-1 is used as a reference for tensile tests and ISO 179-1 for impact tests. The results of this study showed that the maximum tensile strength of the fiber volume fraction was 15% with the cross-direction arrangement of 42 MPa and the maximum impact strength was found in the 30% fiber volume fraction and the cross-direction arrangement of 0.03068 J/mm2. Based on these results, the variation of the fiber volume fraction and the matrix affect the tensile and impact strength.

Abstract

The health condition of the elderly generally has decreased which can cause several physical and mental problems. Elderly aged over 70 years or 60 years who have health problems are categorized as high risk elderly. In carrying out their daily activities inside the house or outside the house, such as going to the mosque, garden, etc., they usually use a equipment called a walker. The types of walkers on the market still have limitations, so they need to be developed in a flexible walker design. The stages used in the flexible walker design development research are compiling a list of requirements, determining reference concepts, developing alternative concepts, selecting concepts, and analyzing techniques and postures for the selected design. The selected concept has specifications, namely the front pedestal functions as a fixed leg or wheeled leg, the arm of the walker holder can be adjusted up and down by 150 mm in height, has a seat that can be folded, and the walker can be folded. In addition, the results of stress analysis on the critical component, namely the main fulcrum, obtained safe criteria where the maximum stress value that occurs is 7.35x106 N/m2 is given still below the yield strength value of the brass material 3.5x108 N/m2. Posture analysis using the RULA method in standing and sitting positions obtained an average final score of 2 in the acceptable category for walker users..
