2025-05-11T22:13:16+00:00

The purpose of this research is as a technological development to encourage the need for a more practical and portable soldering iron. This research aims to design and build a soldering iron that uses battery power, so that it can be used in various locations without relying on conventional electricity sources. The design method includes the selection of main components such as heating elements, lithium-ion batteries and battery safety systems. The assembly process is carried out by considering energy efficiency, safety, and user comfort. The test results show that the battery-based solder is able to reach an optimal working temperature of 277.75 in 135 seconds and has a fairly long usage duration of 2.77 hours according to the 12V 9Ah battery capacity. This tool is considered quite effective for the needs of maintenance and repair of electronic devices in the field and facilitates user mobility.

Libraries are media or institutions that act as library materials, in the form of written materials such as books, journals, and magazines. This media is used as a vehicle for education, research, and preservation of information that is arranged systematically with certain rules. Some libraries still use book borrowing and returning transactions in writing in books, one of which is the library of the Electrical Engineering Department of Pontianak State Polytechnic. This research is intended to simplify the transaction process in the library. The process of borrowing library books and reading membership uses a barcode scanner as input or sensor. Google spreadsheet is used as data storage received from the controller. The process that is passed is the process of data collection of books, the process of borrowing transactions and returning books.

Design and Construction of Digital Electronics Learning Modules to Improve Student Learning Efficiency

2025-01-28T07:47:44+00:00

This research aims to develop learning methods at Pontianak State Polytechnic to improve practicum
efficiency and student understanding in digital electronics courses. The research includes making
learning modules in the form of trainers, antibounce switches, system trials, and tool demonstrations.
The developed module is equipped with a guidebook and includes power blocks, inputs, outputs, circuits,
as well as guidebooks with logic, combinational, and sequential gate circuits. Data was collected through
testing the efficiency of the module by comparing the usage time of the module and IC with the
protoboard, as well as a survey to 3rd semester Electrical Engineering students using Google Forms.
Quantitative descriptive data analysis shows that assembly with the module is faster than with manual
IC. The module feasibility test results showed a percentage of 88% on material, 89% on technical, 92%
on feasibility, and 91% on benefits, indicating that the module is very feasible to use as a companion to
digital electronics courses.

Design and Construction of Prayer Time Schedule Using Arduino Uno-Based P10 Matrix Led Panel as Information Media in Al-Muhtadin Surau

ABSTRACT

Followers of the Islamic religion believe in the obligation to pray 5 times a day, at which time they are carried out. For this reason, knowing the 5 daily prayer times, namely dawn, midday, Asr, Maghrib and Isha is very important for every follower of the Islamic religion in carrying out the 5 daily prayers correctly and as well as possible. For this reason, it is very important to have a prayer schedule. Nowadays, in many mosques and houses, there are usually calendars and displays of eternal prayer times, but the display is so small that it cannot be seen from a very long distance. So many people want to provide information with various interesting media such as prayer time schedules and much more. This makes it easy for people to recognize the device with various other supporting devices. Replacing data text and assembling a prayer time schedule display using a P10 LED matrix panel is currently still relatively difficult for ordinary people. That's why a prayer time schedule was created with the help of Arduino Uno. Prayer schedule information can be updated via Android cellphone with Bluetooth communication. On Android phones, an application can send characters to change the text printed on the P10 led matrix panel. The information sent will be received in the Bluetooth module and processed in the microcontroller and then displayed on the panel. This tool is expected to make it easier for users to view prayer time schedules and change information on prayer time schedules via an Android cellphone with a Bluetooth connection. The aim of this research is that the use of technology from Android and Arduino can be collaborated to make changing prayer time schedule data on the P10 panel faster. and it's easy now.
