Abstract

This research aims to develop a prototype of a laboratory-scale wave generator to explore the potential of river wave energy, which has mostly been focused on marine energy due to its significant potential. The device consists of a container measuring 100x22x30 cm, using a servo motor to generate water ripples and an ultrasonic sensor to detect ripple height. Two propulsion methods are employed: simultaneous and alternating, with more varied ripple patterns observed in the alternating method. Changes in the servo motor’s angle produce three thrust levels with different wave heights: slow (1-2 cm), moderate (2.5-3 cm), and strong (3 cm). The findings highlight the renewable energy potential of river wave energy, which can be harnessed sustainably, reducing carbon emissions, dependency on fossil fuels, while enhancing energy security and job creation.

Abstract

The Carolina Reaper chili, known for its extreme spiciness reaching up to 2,200,000 Scoville Heat Units, requires meticulous cultivation methods for optimal yield. This research emphasizes the importance of proper fertilization and irrigation. An automatic drip fertigation system is introduced to address issues such as inconsistent watering and nutrient imbalance. The system employs waterproof ultrasonic sensors, soil moisture sensors, RTC, and a DHT22 temperature sensor, monitored via Internet of Things (IoT) technology. An Arduino Uno controls the timing, soil moisture, greenhouse temperature, and fertilizer liquid level. A relay-operated solenoid valve is used to automatically supply fertilizer and water. The implementation of this system enhances the efficiency of water and fertilizer use, ensures consistent irrigation, and facilitates plant monitoring. This technology has the potential to improve the yield and quality of Carolina Reaper chilies while reducing labor costs and resource usage in modern agricultural practices.

Abstract

This research aims to explore the utilization of water waves as a source of electrical energy using piezoelectric crystals. In this study, a device is designed to harness water waves to drive an iron marble that strikes piezoelectric crystals, generating electrical signals. The generated electrical signals are then directed to a peak detector circuit to convert the AC signal into DC, which is temporarily stored in a capacitor. This process ensures signal stability before further processing. Subsequently, the stored electrical signals in the capacitor are processed using a step-up boost converter to increase the voltage. The boosted voltage is then regulated by a charger module for efficient and safe battery charging. The generated electrical energy is stored in a battery for future use. This research aims to harness the kinetic energy from water waves and convert it into stable and well-managed electrical energy, thereby potentially supporting the development of wave-based renewable energy technology

Abstract

The current energy crisis encourages the use of renewable energy resources to reduce dependence on non-renewable fossil fuels. The use of renewable energy resources is environmentally friendly, especially in power generation. The research method uses a Hybrid PLTS and PLTB output power control and monitoring system, which monitors both solar power plants and windmills. Data from the sensor is stored according to the time of collection, and monitored via a Smartphone or Laptop device using the ThinkSpeak website via the ESP32 microcontroller. The sensors used include the Non-Inverting Buffer Sensor and the ACS758 Sensor. Temperature, temperature and wind testing is carried out with a DHT22 sensor and an anemometer. DHT and Annemometer sensor data do not use a data storage system, only monitoring.

Abstract

This study aims to design a home security system based on the Internet of Things (IoT) that can be operated via a smartphone application as a solution to security issues in Pontianak and West Kalimantan. Security threats such as burglary and fire are significant in this region, with 1,149 burglary cases reported in Pontianak and 3,470 cases in West Kalimantan in 2020. Additionally, there were 473 fire incidents between 2010 and 2015, primarily caused by electrical short circuits. The proposed system utilizes the Telegram application as a two-way communication medium, equipped with a flame sensor for fire detection and an MQ-2 sensor for gas leak detection. When these sensors detect a threat, the system responds by activating a water pump to extinguish the fire and a buzzer as an emergency alarm. The system can provide real-time notifications to users via Telegram, enabling a quick response to security threats. The findings indicate that this IoT-based security system not only provides effective notifications but also enhances control and convenience for homeowners, especially when they are away from home. It is hoped that this system can improve security and comfort for residents by allowing them to manage their homes more effectively

Abstract

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.Keywords: Learning Module, Digital Electronics, Logic Gate, Combinational Circuit, Sequential Circuit

Abstract

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.

Abstract

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. Keywords: Prayer Times Schedule, Led Matrix Panel p10, Arduino uno
