Abstract

The presence of foreign objects in pepper seeds is one of the things that affect the quality of pepper seeds. Farmers in Bangka sell pepper to pepper collectors. The collectors in this area still inspect the pepper using manual methods without the help of other tools, so there are still foreign objects such as dry leaves or pepper stalks. This method is often inefficient because the precision of each person is different. In this case, we propose to determine the quality of pepper based on the percentage of foreign objects automatically in accordance with the determination of pepper quality standards regulated in the national quality standard (SNI). The authors use YOLOv3 for object detection which is one of the fastest and most accurate object detection methods, outperforming other detection algorithms. However, YOLOv3 requires a heavy computer architecture. Therefore, YOLOv3-tiny, a lighter version of YOLOv3, can be a solution for smaller architectures. This study found that YOLOv3-tiny model has a reasonably high network performance value: precision value of 0.99, recall value above 70%, and F1 score above 80%. While determining the quality of pepper according to the standard quality of pepper (SNI) the value obtained must be below 2%. Then a comparison was made between the detection system and the manual calculation of objects. It was found that in the sample of 26 pepper seeds, the system detected 8.97 seconds faster than manual calculation.

Abstract

Plastic waste poses a significant environmental challenge, particularly in the Bangka Belitung Islands, Indonesia, where Sungailiat receives approximately 68 tons of waste per day. This study presents the development of an automatic plastic waste management prototype that utilizes an Arduino-based control system to address this issue. The system integrates shredding blades driven by a 24 V wiper motor with pneumatic cylinder compression, which is controlled through a network of sensors. The prototype employs a proximity sensor to detect waste at a distance of 1–5 cm, while ultrasonic sensor 1 monitors the shredding chamber at a distance of 5–25 cm to automatically activate the shredding motor. Furthermore, ultrasonic sensor 2 detects the accumulation of shredded plastic in the compression chamber at a distance of 5–10 cm, triggering the pneumatic cylinder for automatic compression. The testing was focused on PET (Polyethylene Terephthalate) plastic waste, demonstrating successful automatic shredding performance; however, the resulting shredded material remained coarse with non-uniform particle sizes. Nevertheless, the compression results after 5–10 minutes were not optimal, producing blocks with insufficient compaction that were easily broken. This indicates the need for further optimization of heater positioning and compression pressure to produce denser plastic blocks for efficient recycling processes. The novelty of this research lies in the integration of shredding and pressing systems into a single Arduino-based automatic prototype that operates sequentially using proximity and ultrasonic sensors, thereby improving the efficiency of plastic waste processing at the laboratory scale

Abstract

Technological advances in the hydroponic agricultural sector have the potential to be developed. One of them is an electrical energy efficiency system. For this reason, it is necessary to test an appropriate energy source. In this study, the test aims to determine the characteristics of the DC generator, the output of the DC generator will function as a battery charging source which is then used for energy efficiency systems in hydroponics. The test is carried out by comparing the pump height to the DC generator, the incoming water discharge and the DC generator rotation. With a pump height of a DC generator as far as 120 cm and a resistance load of 100 , the flowrate is 1L/minute, the DC generator rotation is 162 rpm and the lowest output power is 0.224 milliWatt. With the pump height to the DC generator as far as 30 cm, the flow rate is 25L/minute, the DC generator rotation is 956 rpm and the highest output power is 0.1 Watt. In other words, the greater the flow/discharge of water that enters the generator, the greater the output produced by the DC micro hydro generator.

Abstract

Indonesia is one of the countries in the world that is crossed by the equator that cause Indonesia has a duration of 12 hours (or all day). Hence, the sun can be alternative energy. For instance, it can be used for heating water. Water heaters circulating in the market are still priced in quite an expensive range, so innovation is needed. In this research, a tool is made namely a Solar Water Heater which can track the direction of the sun's rays with the addition of a reflector to reflect sunlight to get optimum heat. This study aims to see the difference between a continuous water cycle where the pump will continue to pump water into the tank through a hot cross-section with a delayed water cycle where the pump will stop for 10 seconds so that the water sits on the copper pipe first. Based on the test results, it was found that the Solar Water Heater can heat water in the tank up to 47.35 degrees Celsius in unstable weather and the optimum method for heating the water is the continuous method which has a difference of 6,47 degrees Celsius with the delay method.

Abstract

Thermoelectric Generator (TEG) is a technology that can convert heat energy into electrical energy directly due to the difference in temperature between the hot side and cold side of the thermoelectric module, known as the Seebeck effect. This study uses a thermoelectric module of the SP 1848 type. An aluminum plate is used as a medium for absorbing heat from a simulated iron temperature with a maximum temperature of 75°C, while the cold side of the thermoelectric module uses a heatsink with a temperature of 33°C and a fan. From the tests carried out, the maximum voltage produced when two TEG modules are connected in series is 1.65 Volt with a temperature difference of 43.13°C. The maximum current generated when two TEG modules are connected in parallel is 3.52 Ampere with a temperature difference of 42°C.

Abstract

Student attendance administration is a crucial process at Al-Quran Education Parks (TPA). In reality, many TPAs ​​still conduct manual administration, as in the three TPAs ​​surveyed in Bangka, making them vulnerable to data loss, inaccurate recording, and slow processing. The solution is to design an intelligent, integrated website attendance system using fingerprint sensors, ESP 8266, and Firebase. The collaboration between biometric technology and Firebase is expected to replace manual administration, improve discipline and accuracy of student attendance data, and increase efficiency. The results demonstrate the system's effectiveness in supporting the attendance process.

Abstract

The increasing demand for clean water requires a monitoring system that is more accurate and practical. Manual water meter recording still has several weaknesses, such as delayed readings, possible recording errors, and the lack of real-time monitoring. This study discusses the design of an Internet of Things (IoT)-based automatic water meter reading system using a flow meter sensor to measure water flow rate and volume. The system was developed using a YF-S201 flow meter sensor, an ESP32 microcontroller, and the Blynk application as a monitoring platform. The research process includes hardware design, microcontroller programming, sensor testing, and result analysis. The test results show that the system can display flow rate, water consumption volume, and estimated usage cost in real-time through the Blynk application. The system also produces readings that are fairly close to those of a conventional water meter. Therefore, the developed system can be an alternative solution to support water usage monitoring in a more efficient and remotely accessible way.

Abstract

This research aims to design and build a microcontroller-based testing tool for timer and contactor contacts, specifically to detect NO and NC contact conditions and to verify ON-delay and OFF-delay timer functions more easily, quickly, and accurately than manual methods. The developed device utilizes a microcontroller and components such as relay modules, push-buttons, and LEDs to automatically test NO and NC contact states and monitor timer functions. The system operates by applying a test signal to the contacts under inspection, reading changes in load current and voltage, and displaying test results in real-time. Research results demonstrate that the device effectively detects contact conditions, displays status information instantly, and measures time delays with millisecond precision. Furthermore, the device identifies faulty or unstable contacts, thereby facilitating the analysis of component conditions. Based on testing outcomes, the tool is considered more practical, rapid, and efficient than manual testing using a multimeter. Thus, the designed microcontroller-based testing tool successfully meets the research objectives and holds potential for use as an aid in laboratory practice, education, and electrical equipment maintenance.
