Abstract

Pekerjaan perawatan dan pemeliharaan mesin merupakan salah satu prioritas utama dalam menjamin kehandalan operasional mesin yang harus terkontrol dan termonitor. Monitoring perawatan dan pemeliharaan mesin central utility di PT. Phapros Tbk, dilakukan secara manual. Pelaksanaan pekerjaan seringkali tidak sesuai dengan jadwal yang telah ditentukan. Administrasi pekerjaan belum berjalan dengan baik.Salah satu sistem yang dapat digunakan untuk membantu pekerjaan perawatan dan pemeliharaan mesin central utility di PT. Phapros, Tbk adalah aplikasi monitoring smartphone berbasis android. Aplikasi ini menampilkan informasi spesifikasi dan fungsi tentang mesin - mesin central utility, jadwal pekerjaan, informasi personil teknisi dilengkapi dengan speedcall untuk menghubungi teknisi secara langsung, catatan pekerjaan serta record data maintenance. Pembuatan aplikasi monitoring perawatan dan pemeliharaan mesin central utility di PT. Phapros Tbkini menggunakan software berbasis Java dan XML. Pengembangan aplikasi Android menggunakan IDE (Integrated Development Environment) Eclipse Kepler sebagai emulatornya. Catatan pekerjaan dan record data maintenace tersimpan dalam memori internal dan dapat ditampilkan dalam Personal Computer.Administrasi hasil pekerjaan dapat terdata dengan baik. Serta dapat memberikan informasi berkaitan dengan mesin, teknisi, dan catatan pekerjaan perawatan dan pemeliharaan mesin central utility di PT. Phapros, Tbk.

Abstract

Design of Smart Home Automatic Control with Communications Via Bluetooth HC-05-Based Microcontroller Arduino and Android, will provide all the comfort, safety, security and energy savings, which takes place automatically and programmed via microcontroller, the house or building. Design of Smart Home Automatic with Control Communications Via Bluetooth HC-05-Based Microcontroller Arduino and Android is intended for automatic control processes. The system consists of seven sensors, keypad password for security doors, HC-05 Bluetooth GSM alarm application and device control applications aktuaktor, and aktuaktor buzzer, dc motors, lights, fans and fan dc exhausting. Among these sensors is a PIR sensor to detect theft, sensor MQ6 to detect leakage of LPG gas and smoke from fires, sensor HC-SR04 ultrasonic for automatic garage doors, fire sensors to detect a fire, the sensor LM35 to detect the temperature of the room, when the room temperature is hot the fan will be on automatically, when the cold room temperature will shut off the fan and LDR sensor to detect the intensity of light during the day which turn the lights off automatically and vice versa, thus saving energy. Homeowners can also control lights and monitoring sensors with android phones that are connected with communication via Bluetooth HC-05 microcontroller arduino, and can receive GSM alarm application sensors such as calling and sms. Test results are used UART communication data transmission between the microcontroller serial monitor monitor has an error of 0 % . HC - 05 Bluetooth can accept orders at the farthest distance of 11 meters . The fire sensor can work well when the fire was 110 cm . Sensor HC - SR04 is already working with an error rate of 0.3 %, so the accuracy of this tool by 100 % - 0.3 % = 99.7 % .Keywords : Security Door , Bluetooth HC - 05 , Microcontroller Arduino and Android , Application Control and Application GSM alarm.

Abstract

Perkembangan dunia medis saat ini tingkat efisiensi waktu dan ketelitian sangat menentukan, salah satu alat penunjang di bidang peralatan kedokteran adalah electronic couter, yang digunakan pada saat tindakan khitan dan pemotongan/ cutting. Tujuan penggunaan alat ini adalah untuk mengurangi atau meminimalisir perdarahan, tanpa jahitan,  dengan nilai estetika lebih baik, karena pembuluh darah yang terbuka di daerah luka langsung dapat ditutup. Sebelum ditemukannya alat ini, teknik pembedahan dilakukan hanya dengan menggunakan instrumen konvensional, yaitu berupa pisau bedah. Dampak penggunaan instrumen ini dapat mengakibatkan pendarahan pada saat dilakukan tindakan pembedahan. Berdasarkan latarbelakang tersebut penulis ingin membuat alat electronic couter yang mampu memudahkan dokter khitan dalam pekerjaannya. Dengan interactive Control Display, alat ini mampu menampilkan suhu panas pada filament prob logam yang akan digunakan untuk tindakan pemotongan jaringan kulit. Kata Kunci :Electronic Couter, Cutting, Control Display

Abstract

 Syringe pump is a tool for inserting high-dose drug fluids given to patients. The accuracy and accuracy of the amount of fluid given to this device is quite high. The need for this tool in hospitals is very large, but in terms of the economy the price of the equipment is still very expensive so it is not affordable to small hospitals. The purpose of making a syringe pump is to be able to meet the needs of the syringe pump in small hospitals so that it can save on budget expenses. Therefore a syringe pump is designed, designed using the Arduino Nano as a control system, display flow speed with 16x2 LCD, stepper motor as a syringe booster according to the regulated flow speed, and buzzer as an alarm when a blockage occurs and the syringe placement is incorrect. Flowrate parameters at a speed of 10 ml / hour, 20 ml / hour, 30 ml / hour, 40 ml / hour and 50 ml / hour.Keywords: Syringe Pump, flowrate, stepper motor, Arduino Nano

Abstract

In a drag race, which is often held by race organizers. The process of determining the jump start and determining who crosses the first finish line still relies on human monitoring. Manually recording (stopwatch) is not enough because there are many inhibiting factors, including: operator, start theft by drivers, recording results, damage to the stopwatch and others. The drag race is often held during the day. The hot weather will cause someone to get tired quickly, in this case it is aimed at the person who is the operator who monitors the theft of the start and the operator at the finish line because the person is in the middle of a very hot track. Based on the reasons mentioned above, it is necessary to have a controller and timer system on the ATMega8535 microcontrollerbased drag race. Making this tool will facilitate the work of humans in obtaining information in the racing arena that does not allow humans to do it manually, so that accurate data is obtained.Keywords: Atmega 8535 microcontroller, jump start, stopwatch
