Abstract

The equipment is not sterile when the health equipment is used repeatedly. Thus, it is at risk of infection. Data published by WHO reveals that one out of every ten hospital patients gets an infection. In developed countries, the number of infected hospital patients reaches 30%, while in developing countries it is at least 2-3 higher. One way to reduce the occurrence of infection is to sterilize medical equipment through a dry heat sterilization process at 1700 C for 60 minutes. The high price of sterilizers means that many health centers and clinics do not have this equipment. The aim of this study was to design a low-cost dry heat type health equipment sterilizer using fuzzy logic as a controller and evaluate the performance of the controller. Regarding to the research result, it indicated that the controller performance evaluation was very good with the highest overshoot value of 1.1%, the steady state error value was 1.1%, and the fastest rise time was 240 seconds.

Abstract

Indonesia is a country that is active in the livestock sector, one of which is cattle farming. However, not many cows are affected by mad cow disease where this disease can be transmitted to humans by consuming the beef itself. This Gina cow disease, if it has been infected with humans, is called Creutzfeld-Jakob disease, where this disease can attack any part of the human body, namely the nervous tissue in the human brain so that it can destroy human brain cells and cause small holes in the brain automatically. gradually, the severity of this disease can claim a person's life if proper medical treatment is not carried out. This disease can cause death within one year after the symptoms are indicated as creutzfeld-jakob disease. To make it easier for an expert to diagnose a disease, a system can be used, namely an expert system with a certainty factor algorithm that determines the confidence value based on the percentage of the final Cfcombine value of the various types of symptoms that exist, so that the percentage value of the resulting confidence level is 89%.

Abstract

Abstract - Magnetic generator is a synchronous generator that uses permanent magnets to generate magnetic flux. In its manufacture, to increase the power, voltage and speed of a permanent magnet generator, simply change parameters such as magnetic flux, number of turns, number of turns, number of magnets and wire diameter. To design or analyze permanent magnet generators,used software is MagNet 7.5to simulate it. This magnet software is based on the Finite Element Method or commonly called FEM. FEM is a computational method that has the concept of breaking the calculation area into small parts and then calculating the parameters one by one in each part. In this study, the variables to be simulated are the number of turns on the stator coil with a variation of 10, 50, and 75 turns. This study uses a combination of 18 slots 16 poles with NdFeB magnets. Then the generator is tested using a 20 ohm load. From the simulation, it can be seen that the number of turns affects the voltage and power generated, where when the generator is given a 20 ohm load with 10, 50, and 75 turns it produces a voltage of 22.3 volts, 88.9 volts and 103.7 volts then for power it produces 61.2 watts, 547 watts and 756.2 watts.Keyword - Coil, MagNet 7.5, Power, Voltage

Abstract

The high rate of motorcycle theft was reportedly caused by the negligence of the owner of the motorcycle itself, including forgetting to double lock and leave the key on the motorcycle. This research offers a new approach to prevent motorcycle theft by designing an automatic double lock system through ignition keys, buzzer reminders for left keys, and coordinator points using GPS to track the position of a motorcycle. Automatic dual locks are designed using a solenoid that locks the front and rear disc brakes automatically when the ignition is in the lock position. The buzzer is activated by using a crossbeam sensor consisting of infrared and photodiode mounted on the ignition key slot and seat lock slot which will sound when the user leaves the key in one of the key slots. The Ublox Neo-6m GPS module is used to determine the coordinates of the motorcycle's position if the motorcycle has been stolen. The test results show that the system can work well. User satisfaction testing shows that respondents agree that the system that has been designed has ease of use, is simple and very useful, seen from the average score of usability factor 4.18, simplicity 4.32 and interactivity 4.38 from a scale of 5.

Abstract

Tindak kriminal pencurian sepeda motor merupakan salah satu tindak kejahatan dengan angka yang terus meningkat setiap tahunya di Indonesia. Pada tahun 2018 terdapat 27.731 kasus pencurian sepeda motor dengan berbagai modus operasional. Terdapat banyak faktor yang menjadi latar belakang tindak kejahatan ini, mulai dari pembobolan stop kontak, kelalaian pemilik kendaraan hingga pencurian dengan kekerasan maupun pengrusakan. Oleh karena itu sangat diperlukan sebuah sistem tambahan pada sepeda motor yang dapat memberikan peringatan kepada pengguna dengan memberikan koordinat lokasi terkini dan dapat mengendalikan kelistrikan pada sepeda motor. Sistem tersebut diharapkan dapat meningkatkan keamanan pada sepeda motor dimana pengguna dapat melacak lokasi hingga mematikan sepeda motor dari jarak jauh berbasis Internet. Sistem ini terkoneksi dengan internet menggunakan modul SIM800L sebagai penghubung antara pengguna dengan sepeda motor.
