Abstract

Photovoltaics (PV) cell adalah sebuah elemen yang dapat melakukan konversi energi dari radiasi akibat panas matahari menjadi energi listrik dengan prinsip semikonduktor. Tegangan dan arus listrik yang dihasilkan sel surya dipengaruhi oleh tingkat intensitas radiasi cahaya matahari dan temperatur udara lingkungan. Alat yang dibuat dalam penelitian ini didesain dengan menggunakan metode lookup table yang dibuat dengan memakai 2 motor sebagai penggerak sumbu x dan y dalam menentukan koordinat dari posisi matahari yang digunakan sebagai penentu intensitas radiasi matahari di Pulau Batam. Perangkat ini juga terintegrasi dengan waktu menggunakan real time clock module.

Abstract

Sei Temiang Livestock in Batam, produce roundabout ±50 m3 of cow faeces each month. Usually, some of this waste is taken away by villagers to be used as raw material of fertilizer. To increase its value, the excrement can be utilized as source of alternative energy before the remnants are applied as organic manure. This research use baloon type as the digester of biogas power plant due to reasons such as simple installation, easy to be overhauled, and the cost is quite affordable. This prototype use a mixture of cow excrement and water with proportion of 1:1. Gas equivalent to 624 litre can be gained from 1 plastic drum which is able to turn on the electricity for 35 minutes with power capacity of 700 watts.

Abstract

Electric energy monitoring device on smartphone-based refrigerators are intended as part of an energy saving campaign. This device works with the principle of regulating the power of the refrigerator based on the parameters of the temperature and starting time of the refrigerator. If the temperature has stabilized, the refrigerator will automatically turned off so that electrical energy consumption can be reduced. This device is also connected to an Android-based application so that the device's performance can also be regulated via mobile phones with certain variables.

Abstract

Flow Meter Trainer Kit is designed because of the limited associated laboratory equipment at Politeknik Negeri Batam. Flow Meter Trainer Kit is a measuring tool for fluid flow which is equipped with the addition of pressure in the form of visual aids. In general, the process of water flow begins with a full filling of water tanks and then the pump will work to flow the water through pipes, passing pressure meters and rotameters whose duty is to read the results of fluid flow discharge measurements while adjusting the amount of fluid flow. Furthermore, water will flow through the water flow sensor and back into the tank. The practicum module will be developed based on this trainer kit.

Abstract

Brushless DC motor is applied in many field of industries, one of which transportation sector. The operation of BLDC motor need a speed control system as commutation process since it does not applied any brush. This research using an Arduino nano as its microcontroller to regulate the switching driver mosfet with IR2103 type. This mosfet driver is used to trigger mosfet switching at iverter 3 phase circuit so that power from battery can flow to BLDC motor. Mosfet type is STP75NF75 with Vds 75 Volt and Ids 80 Amps, while type of motor used is BLDC 350 watt and 36 Volt. The BLDC motor has Hall Effect sensor as rotor positioning detection. As for the commutation process, PWM is used as pulse modulation which is represented the motor speed and frequency of PIN default of Arduino. Speed earned is 224-340 rpm with power consumption of 20-21 Watts.

Abstract

This research was conducted to increase the reliability of UVC lamp irradiation in killing viruses. Since it was first discovered in November 2019, the COVID-19 pandemic has spread all around us and claimed many lives. Various precautions have been taken by the government and individuals. One of the preventions that can be done is to sterilize the room or object surface by using UV light. To kill the virus, type C ultraviolet (UV) light can be used. With a dose of 220J/m² it produces a reduction in the SARS-CoV-2 or covid-19 virus in the air or a surface. The problem that arises is, the UVC lamp used is only limited to on-off with an erratic duration. This tool is expected to be able to perform calculations automatically to determine the duration of the irradiation just by entering the room area information. For user safety when using UVC rays, this tool will also be equipped with a remote control and presence sensor.

Abstract

The Trainer Kit is one of the tools that supports the learning process of the Thermodynamics Lab Course. The objects ejection tool design is created with a 3D printed catapult movement system. The main components of the objects Ejection Speed ​​Trainer Kit are: Use the ultrasonic sensor HC-SR04 as a guide for the desired firing distance, a stopwatch as a measure of time spent throwing objects using the TTP223's capacitive touch as a start and stop clock. Load cell as a measure of the weight of the objects. Meter reading results are displayed on a 20x4 LCD with an i2c module and calculation of velocity values ​​using Visual Basic 6.0. Results of a load cell experiment measuring 6 different materials weighing between 5 and 63 g with an average measurement error of 1.2%. As result of ultrasonic examination measured in increments of 3 to 100 cm, the measurement error is 0% at the maximum distance of 70 cm, and the error is 1.1% at 70 cm or more. The result of the timer experiment using TTP223 in 15 tests has an arithmetic error of 0.37%.

Abstract

In the industrial world, many instruments are installed as tools and devices used for measurement and control in a larger and more complex system, especially at the Tanjung Uncang Gas Power Plant in Batam. To ensure the accuracy of measuring instruments and instrument devices are functioning properly, periodic maintenance or recalibration is required. In general, every calibration of the measuring instrument is carried out by an external party to the company, and it requires additional operational costs for the company. From the results of observations in the field, the author tries to make one simple calibration tool, namely the pressure gauge dead weight tester which is only used for internal company use. This tool can work with a pressure range of 0-100 psi using a weight of 1 kg to 17 kg. which has been tested to calibrate the pressure gauge type C bourdon 2.5 bar and 7 bar with a small error between 0% - 3% and by analysis using linear and polynomial regression methods, the data generated in testing this tool is close to a value of 1 (R Square) which can be used as a reference for the pressure gauge calibration process with a range of 0 - 7 bar.
