Abstract

Micro Hydro Power Plant (PLTMH) is an alternative source of electrical energy for the community. PLTMH provides many benefits, especially for rural communities throughout Indonesia. When other energy sources start to run low and have a negative impact, water becomes a very important source of energy because it can be used as an energy source. PLTMH is a small-scale power plant that uses hydropower as its driving force such as irrigation channels, rivers, or natural waterfalls by utilizing the waterfall height (head) and the amount of water discharge. In rivers, there is the potential for sufficient water availability throughout the year, reliable discharge, suitable contours, and has been used for MHP. However, this river has decreased the electrical power it produces. Therefore, in this PLTMH river, it is necessary to analyze and recalculate the electric power generated by optimizing the water drop point, using an 8-inch pipe to produce a tangential force of 814.28 N, then using a 3-inch pipe to produce a tangential force of 100, 62 N and using a 2-inch pipe produces a tangential force of 25.37 N.

Abstract

Baterai Lithium Polymer (Li-Po) dipilih sebagai sumber daya robot dikarenakan baterai Li-Po karena memiliki bobot yang ringan dan kapasitas penyimpanan listrik yang besar. Namun untuk mengetahui daya baterai yang digunakan, para pemilik robot harus menghentikan robot kemudian dilakukan pengukuran baterai mengunakan alat ukur. Penelitian ini bertujuan memantau nilai tegangan pada baterai Li-Po yang melalui motor penggerak pada robot sepakbola beroda tanpa menggunakan alat ukur dan hasilnya dapat ditampilkan pada komputer maupun PC secara nirkabel. Percobaan dilakukan menggunakan peralatan sensor tegangan dan modul wifi nodeMCU. Hasil dari penelitian ini sensor tegangan dapat membaca data dan didapat nilai standar deviasi 0,39 dan error rata-rata 0,43 yang menunjukkan bahwa sensor memiliki tingkat akurasi yang tinggi. Sementara untuk proses pemantauan sensor berjalan dengan lancar tanpa ada kendala.

Abstract

This study discusses tools for digital current monitoring using an Arduino-based ACS712 sensor. The current sensor ACS712 5A uses the principle of hall effect and is a current sensor whose circuit complexity is simple. The purpose of this microcontroller is to read data obtained from the sensor using the Analog to Digital Converter (ADC) feature and then display it in the serial monitor. The ATMEGA328 microcontroller is assisted by a current measuring circuit equipped with a sensor mounted in series against the circuit to be measured in order to measure the current flowing in the circuit. The test results show that the sensor can measure the current value at its peak value with an error value of -0.066 and a standard deviation value of 0.011419. Based on the test results it can be seen that the tool can work well and has a good accuracy rate.

Abstract

Automatic plant watering system can help users in caring for plants. Along with the development of technology, it is possible to monitor and control using the Internet of Things (IoT) from anywhere and anytime as long as the device is connected to the internet. The system designed in this study performs watering on chili plant automatically and in real time monitored through the Blynk application on a smartphone. Automation is carried out based on the moisture value parameter obtained from the capacitive soil moisture sensor as input and the NodeMCU ESP8266 as the controller. The output of the system is water sprinkling that comes out through a 12V DC water pump as an actuator and the Blynk application as a monitor and controller via IoT. Automation and monitoring through smartphones using the Blynk application in this study have been successfully carried out. Watering can be done regularly according to predetermined time intervals automatically and the amount of water given to plants according to their needs. At a humidity that is less than 60% and the schedule is appropriate, the pump will run for 4 seconds with a water discharge of 116.32 ml which has been adjusted to the volume of soil and water needs of chili plant.

Abstract

One of the fish commodities consumed by the Indonesian people is catfish because it tastes good. Cultivation of catfish requires special attention regarding feeding because if it is not enough it can cause the fish to become cannibals, whereas if too much feed can cause disease. Therefore, it is necessary to monitor and control the provision of fish feed on a scheduled basis. This study aims to facilitate catfish farming in automatically scheduled fish feeding by utilizing the Internet of Things (IoT). This system is built using a NodeMCU micro controller which is connected to a Real Time Clock (RTC) sensor to adjust the feeding schedule. In addition, ultrasonic sensors are used to monitor feed conditions and servo motors to open and close the fish feed storage valve. This study succeeded in providing catfish feed automatically and on time according to a predetermined schedule, namely at 06.00 am, 12.00 noon, and 18.00 pm. Timing is based on the active hours of catfish. The system has also been successfully monitored and controlled remotely via the internet using the Blynk application. In addition, the system has also been able to identify the remaining feed reserves remaining in the storage container. This automatic feeding system has been operating in accordance with the purpose of the system, which is to provide fish feed according to the feeding hours of catfish so that cannibals or fish that are sick with ammonia are not found from leftover feed that is not eaten by catfish.

Abstract

Lately the planting of corn has increased and increased in several areas. The increasing popularity of corn is due to its high economic value. Corn that has been harvested cannot be sold immediately because it must meet certain moisture content requirements. Farmers must know the maximum value of the moisture content in the corn kernels resulting from the harvest to meet one of the standards set by the industry. The water content contained in corn kernels can have a big influence on determining its quality or selling value. This study aims to design and implement a device for detecting the moisture content of corn kernels as a tool to help farmers produce dry and good quality corn kernels. This research uses an Internet of Things (IoT) based method by sending the corn moisture content and ambient air temperature values to a mobile phone via the Blynk application. The components used are the NodeMCU ESP2866 microcontroller, YL-69 sensor, DHT-22 sensor, 16x2 I2C LCD, and battery. The results of this study have been able to make a water content detector tool on corn kernels based on IoT that can work well. From several tests carried out at night and in the morning, a low error rate of 2.3% was found on the DHT-22 sensor, while on the YL-69 sensor the tests were carried out on three types of corn samples, namely dry, medium, and dry corn kernels. and wet obtained a low error rate of 3.1%.
