Abstract

Indonesia is an archipelagic country where each island is always surrounded by the ocean, as for the potential that can be used for renewable energy. The ocean tides are one of the natural phenomena that cause changes in sea level at certain times every day and will affect fishing activities and will affect the flow of the estuary, seeing the characteristics of Indonesian marine waters in general, especially in the Bangka area which is useful for human activities, especially those who related to the sea. Therefore we need a device that can monitor the flow of tidal currents of sea water. The purpose of making this device is to make a device that can measure and determine the current speed and sea level at the estuary of Air Kantung using an Arduino-based program. This method of measuring the speed of tidal currents is based on the principle of turbine rotation which is then read by the optocoupler sensor while the measurement of sea level is based on the principle of constant with ultrasonic sensor readings. The device can save the measurement results into a database which is then stored on the SD card data and can then be displayed on the LCD. The results of testing the optocoupler sensor at the current flow velocity with a comparison of the tool made with a tachometer obtained an average error of 1.17%. While testing the water level with an ultrasonic sensor by comparing the sensor value to the height size with an average error of 1.01%. The monitoring device for current flow and height on tidal flow tested 3 times with the results of measuring current velocity of 0.72% device error and 99.22% accuracy while measuring sea water level of 0.74% device error and 99,26%  accuracy, obtained from comparing monitoring devices with tachometers and meters.

Abstract

The scarcity of LPG for the size of 3 kilograms (3KG subsidized LPG) is caused by the implementation of government regulations regarding subsidized 3KG LPG in the field. To overcome these problems, a 3KG LPG gas sales system was designed by utilizing e-KTP as a condition for purchase transactions. This system works by reading the ID of each customer's e-KTP using an RFID reader sensor MFRC522. NodeMCU ESP8266 is used as a microcontroller as well as a wifi module so that the device can connect to the internet network. The website-based application is implemented as a system portal and a place to store customer data. The features provided in the application include recording and checking customer ID and recapitulation of 3KG LPG sales transactions in real time. Customer ID recording is done by entering the name, NIK and address, accompanied by an edit feature if there is a change or update of customer data. The results obtained from the experiment show that the RFID reader sensor can detect e-KTP well at a maximum distance of 0.5 CM with the e-KTP position parallel to the RFID reader. KTP and transactions are limited to 3 purchases per month e-KTP ID.

Abstract

 A generator is a machine that is needed to produce energy that is almost used all over the world. There are two kinds of generator magnetic field generators, there are those that use permanent magnets and non-permanent magnets with generation using an excitation system. From the two magnetic sources above, I conducted research using non-permanent magnets aimed at knowing the magnetic flux produced. Because the magnetic flux produced is not constant, a study is needed to find out a good excitation source to produce a constant magnetic flux and produce electrical energy as desired. The generator has two main parts, namely the satator and the rotor where the stator is a stationary part and has the function of generating energy while the rotor is a moving part and has the function of generating a magnetic field. In my research, I changed the sator part as a generator of electrical energy. The results obtained from testing this non-permanent magnet generator are 6 experiments using different stator coils. From the results of these tests, the results of the AC power supply were obtained using a coil with the lowest inductance value (225uH) 0.049Vac and using a coil with the highest inductance value (49.8mH) 1.58Vac. From the test results, it can be concluded why the resulting voltage is too small for the magnetic flux generated because the value is not constant, it can affect the load, as well as rpm rotation and other things.

Abstract

The component that is often used in practice is the relay. However, in practice, students often have problems when using relay components due to damaged relays. This happens because there is no tool to detect a damaged relay quickly. To overcome these problems, a microcontroller-based relay tester was made that can quickly check the feasibility of the relay. Which aims to detect a damaged relay quickly. Where the measurement process is by connecting the relay to the available socket, then the output on the relay will be processed by Arduino and the results will be displayed on the LCD and LED. The output on the relay is OK if it's still functioning and Error if it's damaged and the LED is for displaying the test light, if one of the lights goes out, it means the relay is an error, and if there's no damage, the lights will all turn on. From the results of testing more than 10 times testing the tool, it was found that the tool functions well and is accurate. Comparison data was also obtained when testing relays using a relay tester that was made, the time when checking only needed 01.18 seconds for every 1 relay. And for the 10x experiment of relay testing using a relay tester, alternating between 5-foot, 8-foot and 11-foot relays only takes 13.2 seconds.

Abstract

The Bangka Belitung Islands are an archipelagic area which is located at 104°50' to 109° East Longitude and 0°50' to 4°10' South Latitude, there are 6 districts and 1 municipality, and with a population of 1,473,165 people. Bangka Belitung is famous for its tin mines, almost 80% of its tin production comes from Bangka Belitung, apart from that, the marine sector also has a distribution role in regional PAD supplies. With the support of fishing boats, fishery products in 2022 will be 196,704 tons/year. To increase fishing capacity in the future, facilities are needed that can support more fishing capacity, apart from ships with larger capacity, they must also be accompanied by other facilities, namely in terms of energy, both for engines and for lighting. To develop renewable energy to support the maritime sector, a system is needed to supply energy, especially to fishing boats, to reduce fuel dependency. By using a clean and efficient energy-generating tool, namely by using a solar cell, with a capacity of 100 wp, a 12Volt/40 HA battery can produce 480 watts of power, so you can light 10 lights with a capacity of 15 watts for 5 hours, meaning you can save fuel by 20-30%.

Abstract

Many people in general still use manual weight measurement, even though manual weight measurement cannot distinguish between fat mass and non-fat mass. Therefore, in this study, the authors created a tool that can measure body fat percentage using the Bioelectrical Impedance Analysis (BIA) method. The BIA method is a method of measuring body fat levels by sending an AC current at a certain frequency to the body. Then by measuring the voltage generated, it can be known the magnitude of the impedance value in the human body. In measuring fat, the authors chose the hand-to-hand method. Starting from generating an AC signal with a frequency of 50kHz by the Oscillator circuit, it is then processed by the Howland circuit so that the current sent to the body is constant with a value of 0.22mA. This tool uses a load cell sensor as a body weight detector and an ultrasonic sensor as a body height detector. By using these tools the user can determine the value of body weight and height as well as the percentage of body fat with an accuracy of up to 96.22% when compared to Omron products, whereas when compared to manual measurements without methods, the average accuracy value is 82.23%. From this comparison, it can be concluded that fat measurement using the BIA method is more accurate than manual fat measurement.

Abstract

Public Street Lighting (LPJU) is a source of lighting that helps road users when crossing the road at night. But there are still many LPJUs that light up during the day in the absence of a control system. Therefore, this study will discuss the LPJU automatic monitoring and control system using LoRa as a remote communication device. The methodology on this system uses LDR sensors as input and is processed by esp32 devkit v1 with lora communication as data transmission, and the monitoring system uses the website display on localhost phpmyadmin. The results of LoRa communication testing in LOS conditions with a distance of 100 m to 2000 m were successfully sent and received well from LPJU to a laptop even though there was a delay in data reception, while in Non-LOS conditions LoRa communication was less than optimal because there were delays and obstructions when receiving data with a distance of 1 meter to 30 meters. LPJU can be activated and disabled automatically using LDR as an automatic salkar contact, and monitoring results can be displayed on a website page with an internet connection.

Abstract

Goldfish (Carassius Auratus) is a beloved ornamental fish among enthusiasts. In the care of Goldfish, feeding plays a crucial role in supporting their growth, thus the feed provided must correspond to the size, quantity, and nutritional content required by the fish. One way to determine the appropriate amount of feed is by measuring the fish's weight. However, conventional measurements may suffer inaccuracies due to several factors, such as the observer's skill level and the tendency of fish to move. The aim of this research is to develop a system capable of determining the feed amount for the fish based on their weight. In this study, the Author utilizes image processing technology using image segmentation techniques to measure the weight of ornamental fish in determining the appropriate feed quantity. Based on test results, this system can measure weight by simultaneously placing Goldfish in an aquarium, resulting in length accuracy of 88.57%, width of 86.18%, and weight of 86.61%, determining feed quantity at 85.87% accuracy with a feed difference of 1.64 grams. Meanwhile, measuring individual fish/tails produces length accuracy of 92.96%, width of 77.15%, and weight of 94.12%, as well as feed quantity determination at 99.43% accuracy with a feed difference of 0.08 grams.

Abstract

Oil palm is one of the most important crops in Indonesia's plantation industry. In terms of cultivating oil palm, farmers still rely on manual-based systems, such as watering, fertilizing, and applying pesticides. With this tool, it is expected to increase efficiency in managing watering, fertilizing, and applying pesticides to oil palm seedlings, and farmers can monitor pH levels, soil moisture, and weather conditions in real time on the blynk application. This system consists of several main components, namely ESP-32 as a microcontroller hardware and software component. The sensors used are soil moisture sensor, raindrop sensor, and pH sensor. The soil moisture sensor is used to measure the level of soil moisture around the roots of oil palm seedlings. The rainfall sensor will provide information whether it is raining or not. The pH sensor measures the acidity level. Data from the three sensors will be sent in real-time to the IoT platform, namely the blynk application via a wireless network in the form of WiFi. Based on the research results, it can be seen that this tool can measure soil pH levels with a fairly low average error value of 0.0354%. The soil moisture sensor can also measure the soil moisture level with precision according to the actual data. Tests were carried out with three soil samples and tested three times.
