Abstract

Generally, earthquake is measured with a seismometer, a device which is also known as seismograph  that works based on  detection of seismic wave in earth’s crust.  This research designs and implements an earthquake detection using frequency modulation method based on personal computer.  The research results a system and simulation. Simulation shows that in a normal condition the strength carrier is 2,5 % and before the earthquake occurred, the strength carrier is 55%. Frequency modulation method can be implemented  to detect earthquake by building some measurement stations at several   places. Keyword : earthquake, frequency modulation, seismograph

Abstract

PID control has been widely used in industry  as well as been implemented in the control of the liquid level . The research objective is to design  PID controller base on microcontroller  and then apply it on the miniature hopper-conveyor plant to maintain solid levels of raw materials to remain constant . The dimension of hopper is 25 cm long, 20 cm wide and 25 cm high. The design of PID control uses a separate action based on microcontroller and for the  tuning uses open-loop Ziegler-Nichols. The design is implemented in miniature hopper-conveyor plant to move the raw material form of green beans to the hopper using a screw conveyor. The screw conveyor is  rotated by a three phase induction motor with inverter speed drive. Level in the hopper is measured by using an ultrasonic sensor module build-in the data acquisition program . The experimental results of implementation on the miniature hopper-conveyor plant shows that PID control provides good performance such as overshoot occurs in  1 cm, or 0.05 % of set point and risetime shows 280 seconds. Key words: PID controller, microcontroller, Ziegler-Nichols, Hopper-conveyor plant

Abstract

Informatics and Business Institute Darmajaya Bandar Lampung especially Bachelor of Computer System Program will apply FLC subjects on new curriculum in 2015. To increasing knowledge and motivation of students learning of Fuzzy Logic Controler/FLC is needed a trainer kit.          This study aimed to developed  FLC module for trainer kit. The membership function use a triangle.  The singleton fuzzification  use as fuzzifier.  FLC module is designed to have three subset with 9 rules. Fuzzy inference machine use max-min operator while defuzzification  use the Centre of Average. Fuzzy system implemented on ATmega 32 microcontroller then output converted to analogue using a DAC.         Testing is done by providing input voltage variations and measure the outputs and retrieve data from each of the fuzzy operations through data acquisition program. The test show the modules can work in accordance with the fuzzy operation, the output voltage of FLC module in accordance with changes in input voltage.  KEY WORDStrainer kit, fuzzy logic controller, microcontroller

Abstract

Kadar gas amonia menjadi salah satu permasalahan yang kerap terjadi pada    peternakan ayam. Ambang batas maksimal untuk kadar gas amonia yaitu 20 PPM (Part Per Million). Gas amonia muncul karena suhu yang tidak ideal pada kandang ayam. Diketahui bahwa suhu yang optimal pada kandang ayam dengan suhu 300C (Celcius). Kenaikan kadar gas amonia yang tidak terekam juga merupakan permasalahan karena pemilik atau pengelola ayam tidak bisa mengontrol dan mengetahui apabila terjadi kenaikan kadar gas amonia. Dari permasalahan tersebut dirancangnya sistem pengendali kadar gas amonia dengan sensor MQ-135 sebagai sensor yang akan mendeteksi kadar gas amonia dan sensor DHT11 yang akan menjadi sensor yang mendeteksi suhu ruangan kandang ayam. Hasil pembacaan sensor gas dan sensor suhu diproses oleh arduino sebagai mikrokontroler. Sistem ini juga akan menyimpan kadar gas amonia yang terdeteksi oleh sensor MQ-135 kedalam database pada aplikasi monitoring tiap menit agar apabila terjadi kenaikan kadar gas amonia dapat terdeteksi kapan kenaikan kadar gas amonia terjadi. Keluaran dari sistem ini akan ditampilkan kadar gas amonia dan suhu ke layar LCD 16x4 serta mikrokontroler yang mengirimkan signal ke driver relay untuk menghidupkan blower apabila kadar amonia yang terdeteksi melebihi 20 PPM lalu mengeluarkan gas amonia ke luar kandang ayam dan menghidupkan  heater apabila suhu yang terdeteksi kurang dari 30oC untuk mengendalikan suhu kandang ayam.

Abstract

Doors were the first access when entering a room or house. The access of the doors (e.g., office and house doors) should have been given only for certain people. The security system on the doors was very important because it was accessible only for the persons who had authorization. In this study, the security system was built through RFID as a substitute for a house key, a camera as a recorder around the front door of the house, and the camera canals as a controller to capture real time through the telegram application. In the remote control system (IoT) application, there were several menus or commands with different functions that met the needs of the system and the user. Command "/start" was used to activate and connect security applications and systems, command "/portrait" was used to capture conditions around the door, command "/close" was used as a command to lock the door, and command"/open" was used to lock the door.Keywords:Camera, RFID, Nod Mcu, Telegram, and Home Security
