Abstract

Stator Generator is a stator that uses a generator consisting of a coil and a magnet that emits an alternating voltage so that it can rotate the flywheel, the stator generator is a product of the development of the Stator Motor whose production demand is always increasing. The Stator Generator consists of Flywheel Assy and Stator Comp. In the Manufacture Stator Comp process, the longest production process is wire cutting. This research started from finding the problem of long production time. In the process of cutting wire, it is still done manually using cutting pliers by the production operator. To meet daily production needs, this wire cutting process requires two employees to carry out the production process with an ever-increasing target. From these problems, a wire cutting machine based on Automatic Wire Cutting was developed in order to get maximum and efficient production results. Calculations in material selection and cutter angle are also considered so that the results of the wire cutting process are stable and produce good cuts.

Abstract

Electrical energy is one of the most important daily needs for humans. Electricity is used to power tools that are used daily, such as turning on the lights, TV, refrigerator, and others. Electrical energy can be generated easily, there are already many power plants that can create electricity from new and renewable energy such as solar power plants (PLTS) and wind power plants (PLTB). The two generators can be combined to form a new system, namely the Hybrid system. In this study design a hybrid system of solar thermal energy and wind energy. The system formed uses a power storage system that is with a battery. Then the energy from the battery can provide energy to the load. The average power generated from the PLTS design is 0.474 Watt and the average wind generator is 9.378 Watt. Then the average hybrid system produces a power of 0.551 Watt.

Abstract

Crash box is one of the passive safety components in vehicles, especially cars that are designed to reduce the occurrence of injuries to drivers and passengers due to collisions. This study aims to determine the energy absorption of the crash box with a multi-segment circular cross section. The research method used is quasi-experimental, namely by computer simulation using Finite Element Method-based software. The independent variable in this study is the location of the segment connection, including: 1/4, 1/3, and 1/2 of the total length of the crash box. While the dependent variables that are sought include: energy absorption, force reaction, and deformation patterns that occur in the crash box. The crash box will be hit by an impactor with a mass of 103 kg and a speed of 7.67 m/s. From the simulation results, the maximum energy absorption and force reaction values are found in the crash box at connection 1/2 of 1689.7 J and 67718 N, followed by connection 1/3 with values of 1221.2 J and 56127 N, and the last is at 1/4 connection is 1119.8 J and 55443 N. Judging from the deformation pattern, the connection at 1/4 and 1/3 is buckling so that the energy absorption is lower than the crash box at the 1/2 connection. It is concluded that the most optimal design of the crash box with a multi-segment circular cross section is the model at the 1/2 connection because it has the highest energy absorption value of the other 2 models and the deformation tends to be more stable.

Abstract

Fire is an accident that often occurs in the community. For that we need a tool that can provide early warning of a fire. There are many types of fire alarms. We design a fire alarm system using a microcontroller. By using this fire sensor, if a fire is detected, the sensor will send a signal regarding the presence of a fire. Flame sensor will be connected to the microcontroller. In this study using a microcontroller in the form of Wemos D1 and a flame sensor as a fire detection sensor and as an indicator light. The flame sensor itself can detect waves of 760 nm – 1,100 nm. Wemos D1 which functions as a microcontroller will send a signal to turn on the buzzer as an alarm and a dynamo which is used to turn on the pump.

Abstract

A repeatedly used cooking oil is also called as used cooking oil. Used cooking oil from 17 entrepreneurs in Palaran Sub-District is 161,5 liters/day or 50,65 tons/year. Used cooking oil can result in pollution to the environment due to the increasing number of acids and the number of peroxide. The research objectives of this literature study is to find out the effects of the mass adsorbent in the refining process of cooking oil with the activated charcoal adsorbent from sugar cane on the number of acids and the number of peroxide. A lot of sugar cane has a content of cellulose 45%, lignin 18%, Pentosan 32% and others 5%, so it can be used as a material of active charcoal which can be applied as adsorbent for the purification of used cooking oil. The process of refining the oil using adsorption method by varying the mass of active charcoal adsorbent. The collection of secondary data on the research of this literature was sourced from Triyanto (2013), Irmawati and Syahrir (2018) and Bariah (2020) who have examined the mass influence of active charcoal adsorbent on the number of acids and numbers of peroxide. Based on the results of analysis and interpretation of the third data of the journal used obtained information that the mass recommendation adsorbent on mass 6 grams
