Abstract

The development of the Corona virus or COVID-19 in Indonesia is still developing until now. The best way of prevention to avoid the factors that can cause this viral infection, one of which is routine hand washing with soap and water or hand sanitizer. The problem is hand sanitizer that exist now always using hand power to squeeze or spray them like holding/pressing, we can think if this hand sanitizer is for the public, how many hundred hands of different people will hold it, and of course this actually causes infected with the Corona virus. Aim of the study is make two in one equipment (hand sanitizer and handdryer automatic), which means that the equipment can be used for hand sanitizer without having to hold/press/squeeze the hand sanitizer and also have the dryer. The results obtained when the fingers are closer to the hand sanitizer, it will release the liquid in ± 3 seconds, and if the liquid is a gel it will come out in about ± 5 seconds. For the handdryer, it takes ± 2 seconds to remove the hot air.

Abstract

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..

Abstract

Clear water that has been processed into ready to drink in Sumbegedang Pasuruan village cannot yet be distributed to the local village community or other villages, because there is still no equipment for the process of packaging clean ready-to-drink water. Therefore, in this Community Service Activity, a semi-automatic plastic cup sealing machine was made with the sealing mechanism run by a driving dynamo (AC motor) with a push button connected to a microcontroller as the trigger. This Community Service activity is a continuation of Community Service activities in the village of Sumbergedang, Pasuruan which has abundant clear water originating from Mount Penanggungan and has been processed into clean water ready to drink. Clean water that has been placed in a plastic glass container, then for the future can be produced or distributed to the local village community or other villages. Automatic components used for the manufacture of semi-automatic cup sealer machines are PCB, ATMEGA48V-10PU IC, step down transformer, thermostat, heater, digital counter, push button, timer potentiometer, limit switch, relay, PCB cable, motor AC. The machine is only used for one size of 7 oz glass. A machine operation test was carried out to find out if this semi-automatic cup sealer machine met the machine's standard results. Furthermore, an introduction was made along with the process of operating this semi-automatic plastic cup sealing machine to the people of Sumbergedang Pasuruan village. The results show that this semi-automatic cup sealer can be used in the field and for the process of packing clean, ready to drink water in Sumbergedang Village, Pasuruan.

Abstract

The trolley equipment that is typically used in malls or stores cannot be folded or bent to take up enough space for you to move it anyplace. Because using Solidworks software, the goal of this research is to develop a collapsible trolley. The Von Misses stress test was used to test folding and general purpose trolley frames for loads of 35 kgf, 245 kgf, and 875 kgf. According to the findings at a weight of 35 kgf, typical goods carts have a greater Von Misses stress of 796.6e+008N/m2. A regular goods trolley's high Von Misses stress is 7966e+009N/m2 at a weight of 245 kgf. On conventional goods trolleys, the Von Misses stress reaches 962.4e+009N/m2 at the maximal load, which is 875 kgf. Because folding trolleys use hollow iron, which is lighter, it follows that standard goods trolleys have a higher strength than folding trolleys, albeit folding trolleys are considerably more effective.

Abstract

Until now, manual trolleys that are used for goods or as a tool to help move goods from one place to another still use human power, The difference in the design of the trolley that I made and the trolley that is usually used at my research site is that the trolley can be folded which has the advantage of being a place to put the trolley and easy to carry the trolley either in two-wheeled vehicles or in four-wheeled vehicles. This research is based on ideas from the results of research in work areas such as malls, and minimarkets. The folding trolley that is being made at this time can withstand a compressive load test of up to 875kg with one damaged component, namely a broken wheel, while in a medium compressive load test of 245kg with a safe wheel condition there is no damage to the component but the occurrence of curvature on the middle of the trolley, the folding trolley which previously had a height from the tile to the bottom limit of the trolley which was 9cm and when given a moderate compressive load test of 245kg there was a bend of 0.3cm which means the current trolley height is 8.7cm and a low compressive load test was carried out with a loading press 35kg to 105kg the folding trolley does not change in height, which means the trolley is still 9cm. The final results show that this folding trolley can be used in the field.
