Abstract

Tomat merupakan salah satu tanaman populer yang banyak digunakan dalam produksi makanan dan minuman. Untuk mendapatkan tomat dengan kualitas yang baik maka dilakukan proses penyortiran pasca panen. Pada era tekmologi seperti sekarang masih banyak petani yang melakukan penyortiran secara manual. Untuk mendukung petani dalam memaksimalkan hasil panen maka dirancang sebuah penyortir otomatis tomat berbasis arduino uno. Sistem kerja alat ini berupa mesin sortasi otomatis yang dapat menyortir tomat berdasarkan warna kulit dan berat dengan sensor TCS3200 dan sensor load cell. Sistem ini dirancang untuk menyortir tomat dengan 6 keadaan, yaitu tomat matang berat, tomat matang ringan, tomat setengah matang berat, tomat setengah matang ringan, tomat mentah berat, tomat mentah ringan. Untuk setiap keadaan, salah satu dari 5 motor servo akan aktif untuk mendorong tomat ke wadah penampungan. Hasil pembacaan dari sensor TCS3200 berupa nilai RGB, dan hasil pembacaan dari sensor load cell diperoleh deviasi rata-rata sebesar 0,32%.

Abstract

Research has been carried out on designing an IoT-based water quality monitoring and control system in freshwater fish ponds, which aims to produce a tool that is able to monitor and control water quality remotely in freshwater fish ponds, to find out how the tool works in monitoring and controlling water quality over long distances in freshwater fish ponds. This research was conducted by connecting several components, namely using Arduino Mega 2560, WiFi expansion shield, pH sensor, turbidity sensor, DS18B20 sensor, ultrasonic sensor HC-SR04, and two DC pumps. Each sensor is compared with the actual measuring instrument and has an average percentage of error, the pH sensor is compared three times, namely the pH buffer solution of 4.01 with an average error of 2.1%, in the pH 6.86 buffer solution the average error is 0.4 %, and in aquadest solution the average error is 0.7%, the turbidity sensor has an average error of 1.6%, and the DS18B20 sensor has an average error of 0.4%. It can be concluded that the designed tool has been successfully made, and works well, for monitoring it is displayed on the LCD and in the Blynk application, for controlling water can be done through the Blynk application by turning on and off the pump that has been made.

Abstract

Garbage is one of the biggest problems faced by many cities in the world, the lack of awareness to dispose of waste in its place causes waste to scatter and pollute the surrounding environment. This research aims to design an automatic trash bin based on the Arduino microcontroller and to find out how the automatic trash can works with the HC-SR04 ultrasonic sensor based on the Arduino Uno microcontroller. The design of this system uses Arduino Uno. The results of the input and output tests show that the HC-SR04 ultrasonic sensor has a low error rate of 1.2% at a distance of 25 cm and a high of 6% at a distance of 10 cm. The trash can opens the lid automatically at > 30 cm to detect the capacity of waste that has been disposed of into the trash container with a height of 20 cm., the proximity sensor will detect the type of waste being disposed of, and the LCD will display the type of waste that will be disposed of and the servo motor will activate the mechanical system of this device. If the trash can is full, a warning will be sent via the buzzer and the SIM800L GSM module via SMS. The working system of the automatic trash can as a whole can work well according to the design that has been made.

Abstract

Oil palm is the most productive type of plant in producing vegetable oil. The development of the industrial revolution led to an explosion in demand for vegetable oil so palm oil was a major contributor to the country's foreign exchange. Indonesia is one of the countries with the largest oil palm plantations in the world. However, the yields produced are still not optimal due to several factors, namely the condition of soil pH, soil moisture, and the surrounding temperature. Soil contains nutrients such as nitrogen (N), potassium (K), and phosphorus (P) which oil palm plants need in certain amounts to grow. To find out the quality of the soil, several methods are carried out by taking a soil sample and using a soil pH meter, however, this method requires a long time and the measurement is only limited to measuring soil pH. This research produced a system for detecting soil pH, soil moisture, and temperature around the soil on an IoT-based land that will be planted with oil palm, as the controller is NodeMCU ESP32. This tool displays soil pH, soil moisture, and air temperature on the LCD screen and the Blynk application page so that it can be accessed anytime and anywhere. This will make it easier for oil palm farmers to obtain accurate information before planting oil palm on vacant land. After testing and data collection, the soil pH sensor has a good correlation with an error rate of 1.71%, soil moisture of 1.23%, and air temperature of 4.04%. So that this sensor can be implemented on vacant land before planting oil palm.

Abstract

Abstract: Anchovies are a processed food product which in the process goes through several stages, such as salting and drying. This process is done so that the anchovies can last longer. The process of drying anchovies can be done by drying them under direct sunlight. However, this process is less than optimal due to less efficient weather conditions and will take longer. The aim of this research is to design and determine the performance of an anchovy dryer using LPG gas with the support of a solar panel based on an Arduino Uno microcontroller. The components used in this research are the Arduino Uno microcontroller, relay, DHT22 sensor, burner, RTC, LCD, buzzer, solenoid valve, 3 kg LPG gas and 50 WP solar panel. Where 1000 g of anchovies are used. The method used in this research is to design a rack-type box frame, then test the component circuit tool that has been made based on the Arduino Uno microcontroller, and then ensure that the assembled tool runs according to the previous plan. The test results show that the circuit components that have been made work well. This can be seen from the component test results (DHT22, relay, solenoid valve and igniter) which show good function and performance. Anchovies dried at a temperature of 60 for 4 hours have met the water content according to SNI 8273:2016. Keywords: arduino uno;gas elpiji; anchovies ;solar panels;DHT22Abstrak: Ikan teri merupakan produk olahan pangan yang dalam prosesnya melalui beberapa tahap, seperti penggaraman dan pengeringan. Proses tersebut dilakukan supaya ikan teri dapat bertahan lebih lama. Proses pengeringan ikan teri dapat dilakukan dengan menjemur di bawah terik cahaya matahari secara langsung. Akan tetapi proses tersebut kurang maksimal dikarenakan kondisi cuaca yang kurang efisien dan akan memakan waktu yang lebih lama lagi. Tujuan dari penelitian ini adalah untuk merancang dan mengetahui performansi alat pengering ikan teri menggunakan gas elpiji dengan dukungan panel surya berbasis mikrokontroler arduino uno. Adapun komponen-komponen yang digunakan pada penelitian ini adalah mikrokontroler arduino uno, relay, sensor DHT22, burner, RTC, LCD, buzzer, solenoid valve, gas elpiji 3 kg dan panel surya 50 WP. Di mana ikan teri yang digunakan sebanyak 1000 g. Metode yang digunakan pada penelitian ini adalah dengan merancang kerangka boks tipe rak yang kemudian menguji coba alat rangkaian komponen yang sudah dibuat berbasis mikroktroler Arduino Uno, dan selanjutnya memastikan alat yang dirangkai berjalan sesuai rencana sebelumnya. Hasil pengujian menunjukkan bahwa komponen rangkaian yang telah dibuat berjalan dengan baik. Hal ini terlihat dari hasil pengujian komponen (DHT22, relay, solenoid valve dan pemantik) yang menunjukkan fungsi dan kinerja yang baik. Ikan teri yang dikeringkan dengan suhu 60 14℃">  selama 4 jam telah memenuhi kadar air sesuai SNI 8273:2016.Kata kunci: Arduino Uno, Gas Elpiji, Ikan Teri, Panel Surya, DHT22
