ABSTRAKPenetasan telur umumnya dilakukan dengan menggunakan bantuan mesin penetas telur. Namun dalampemakaian mesin penetas telur dibutuhkan suplai listrik agar mesin penetas telur bekerja, dan apabila peternakhendak memeriksa kondisi mesin, peternak harus datang melihat secara langsung. Ketika terjadi listrik padammaka mesin penetas telur akan mati sehingga mesin tidak bekerja, hal ini dapat memengaruhi penetasan telur.Untuk mencegah mesin penetas mati perlu diberi sumber listrik cadangan yang otomatis digunakan ketika sumberlistrik utama terputus. Sumber listrik cadangan yang digunakan pada penelitian ini adalah aki 12V 20Ah denganrangkaian automatic transfer switch (ATS) dengan tujuan agar mesin penetas telur akan secara otomatismenggunakan listrik dari aki saat terjadi listrik padam. Ketika memasuki hari ke 21 proses penetasan, peternakharus rutin memeriksa mesin penetas untuk memastikan adanya telur yang telah menetas. Untuk membantupeternak dalam mengetahui keberadaan anak ayam yang telah menetas, dibutuhkan sebuah sistem yang dapatmendeteksi adanya gerakan dari anak ayam dan dapat mengirimkan notifikasi kepada peternak dan mengirimkangambar anak ayam yang bergerak tersebut. Dari implementasi yang dilakukan didapatkan hasil bahwa mesinpenetas telur dengan total daya lampu pemanas 140W dapat menyala selama 3,5 jam (direkomendasikan hanya 3jam) dengan menggunakan sumber listrik dari aki 12V 20Ah. Selain itu sistem pendeteksi gerakan mampumendeteksi adanya gerakan dari anak ayam dan mengirimkan notifikasi beserta gambar kepada peternak denganbantuan bot Telegram. Namun terdapat kekurangan pada sistem pendeteksi gerakan ini, karena sistem mendeteksigerakan melalui image processing dengan metode background subtraction, maka adanya perubahan cahaya yangditangkap kamera dapat dianggap sebagai gerakan oleh sistem sehingga sistem dapat salah mengenali gerakan.Kata kunci: Automatic transfer switch, Bot Telegram, Image Processing, background subtraction.ABSTRACTHatching eggs is generally done by using the help of an egg incubator. However, in using an egg incubator,a power source is needed for the egg incubator to work, and if the farmer want to check the condition of themachine, the farmer must come to see it in person. When there is power outage, the egg incubator will turn off sothe machine doesn’t work, this can affect the hatching of eggs. To prevent the incubator from stop working, it isnecessary to provide a backup power source that is automatically used when the main power source is cut off.The backup power source used in this research is a 12V 20Ah battery with an automatic transfer switch (ATS)circuit with the aim that the incubator will automatically use electricity from the battery when there is a poweroutage. When entering the 21st days of the hatching process, farmer must routinely check the incubator to ensurethere are chicks that have hatched. To assist farmer in knowing the existance of hatched chicks, a system that candetect the movement of the chicks and can send notification and the picture of moving chicks to farmer is needed.From the implementation, it was found that the egg incubator with a total heating power of 140W can run for 3.5hours (recomended only for 3 hours) using a power source from a 12V 20Ah battery. In addition, the motiondetection system is able to detect the movement of chicks and send notification along with the image to farmerwith the help of the Telegram bot. However, there are weakness in this motion detection system, because thesystem detects the motion through image processing with the background subtraction method, any changes in thelight captured by the camera can be considered as motion by the system so that the system can misrecognizemovement.Keywords: Automatic transfer switch, Telegram bot, Image Processing, background subtraction

ABSTRAKAyam merupakan salah satu sumber protein yang murah dan mudah didapatkan oleh masyarakat Indonesia.Seiring perkembangan dan pertumbuhan penduduk Indonesia yang sangat pesat, hal ini berbanding lurus padatingkat konsumsi masyarakat pada daging khususnya pada kebutuhan daging ayam. Ayam dapatdikembangbiakkan dengan mudah oleh masyarakat biasa maupun peternak, untuk dapat menetaskan telur ayamdibutuhkan tempat dengan suhu dan kelembaban yang sesuai dengan telur ayam agar dapat menetas. Penetasantelur ayam membutuhkan waktu berkisar 18-21 hari, yang artinya telur ayam berada di dalam mesin penetas telurselama selang waktu tersebut dengan kondisi mesin penetas telur harus menjaga suhu dan kelembaban didalamnya. Pada sistem ini akan membaca nilai suhu dan kelembaban dari ruang penetasan dengan menggunakansensor DHT21, data suhu dan kelembaban tersebut akan digunakan sebagai acuan untuk mengontrol aktuatorberupa relay yang terhubung pada bohlam. Hal tersebut bertujuan agar suhu pada ruang penetasan tetap terkontrolsesuai pada titik optimum untuk penetasan telur ayam yaitu pada suhu 37-40°C. Selain itu data suhu dankelembaban juga akan dikirimkan ke sistem IoT dan catu daya (melalui single board computer). Selain membacanilai suhu dan kelembaban di dalam ruang penetasan, sistem ini juga akan mendeteksi adanya suara ayam yangtelah menetas dengan bantuan dari modul voice recognition. Hasil pengujian secara keseluruhan selama 39 haripenelitian dilakukan perlakuan pada telur dengan memberikan set point temperatur pada 37°C-38°C. Penentuanset point temperatur tersebut didapatkan dari berbagai macam literatur yang mengatakan suhu dapat ditetapkanpada 35°C-40°C. Untuk tingkat kelembaban pada ruang mesin penetas telur didapatkan pada nilai 43,10%-47%RH tanpa memberikan perlakuan khusus seperti menambahkan mist maker maupun kipas. Pada kondisiumum untuk melakukan penetasan telur diharuskan memberikan perlakuan khusus kepada telur hingga hari ke 18dengan kelembaban 50%-55%RH dan 60%-65%RH pada hari ke 19-21.

Along withthe rapid development and growth of Indonesia's population, this is directly proportional to the level of publicconsumption of meat, especially the need for chicken meat. Chickens can be easily bred by ordinary people andbreeders, to be able to incubate chicken eggs, it takes a place with a temperature and humidity that is suitable forchicken eggs to hatch. Hatching of chicken eggs takes 18–21 days, which means that the chicken eggs are in theincubator during this time, with the condition that the incubator must maintain the temperature and humidity init. This system will read the temperature and humidity values from the hatchery using the DHT21 sensor, thetemperature and humidity data will be used as a reference to control the actuator in the form of a relay connectedto the bulb. It is intended that the temperature in the hatchery remains controlled according to the optimum pointfor hatching chicken eggs, which is at a temperature of 37–40°C. In addition, temperature and humidity data willalso be sent to the IoT system and power supply (via a single-board computer). In addition to reading thetemperature and humidity values in the hatchery, this system will also detect the sounds of hatching chickens withthe help of the voice recognition module. The overall test results for 39 days of the study were carried out on eggsby giving a temperature set point at 37°C–38°C. The determination of the temperature set point is obtained fromvarious literatures which says that the temperature can be set at 35°C–40°C. The humidity level in the eggincubator room was obtained at a value of 43.10%–47%RH without giving special treatment such as adding amist maker or fan. In general, conditions for hatching eggs require giving special treatment to eggs until day 18with a humidity of 50%–55%RH and 60%–65%RH on day 19–21. Carrying out monitoring designs for eggincubators can be done using the DHT21 sensor. The potential for hatching chicken eggs using a chicken eggincubator that has been studied is only 3.33% of the total 60 eggs hatched. The small number of eggs that can behatched is due to an error during the hatchin

This study aims to ensure the estimation of power usage time in portable power supplies. The main component of this system is a portable power supply which contains a battery as a power supply, a current shunt as a current sensor, and Arduino as a microcontroller. The portable power supply will store energy from the solar cell through the solar cell power supply. When using a portable power supply, the parameter to consider is the output current because it will be an assessment of power usage in units of time, because not everyone knows the battery voltage limit. The current value is obtained from the Current shunt current sensor. The conversion of the current value into an estimate of time is by calculating the power equation. Current Shunt sensor is a sensor that has positive and negative poles with the ability to read currents up to 100A 60 mV. This shunt current sensor requires a signal conditioning circuit that is used as an amplifier circuit on the sensor. This circuit contains IC AD620 as an op-amp which has advantages at high frequencies and has a high level of precision. The time value will be displayed on the LCD 16x2 contained in the portable power supply. The load contained in this experiment is a 25W DC load and 100W AC through an inverter.Keywords: Estimated power usage, current sensor, power supply, battery

Clungup Mangrove Conservation (CMC) is a marine tourism area that has ecotourism principles. As an ecotourism place, of course, the CMC area needs development in terms of facilities, one of which is the provision of environmentally friendly electricity with alternative energy through solar cells. The solar cell system is placed in a box called the solar home system. This solar home system includes a solar charge controller, automatic switch, and inverter which when operating will produce hot air so that it has a high temperature and can affect the performance of the devices contained in the solar home system itself. So we need a temperature monitoring system so that the temperature at the Solar Home remains stable. This system is designed using a DHT11 temperature sensor which is controlled by an ESP8266 microcontroller. This ESP8266 is connected to the internet network so that sensor reading data can be sent to users via the Blynk application and QoS parameter measurements are also carried out from the ESP8266 to the Blynk server to determine the quality of data transmission. The test of sending data from ESP8266 to the Blynk server monitored through the Wireshark application has a delay of 196 ms, jitter of 196 ms at 0% packet loss, throughput of 2.84 Mbps. The use of a data package for 1 month with a calculation of 1 month consisting of 30 days obtained 1.41 GB.Keywords: Clungup Mangrove Conservation, Solar Home System, Temperature, IoT

Crop failure due to high rainfall is a threat to farmers. One solution to overcome this problem is to cultivate melons in a greenhouse. However, this can result in a significant increase in temperature so that the soil in the planting medium dries quickly. In this study, an algorithm was implemented to control the readings of dissolved water content in the planting medium by non-invasive capacitive sensor pieces which were carried out alternately using a decoder, as well as reducing reading noise using the Kalman Filter algorithm. The algorithms designed include reading sensor data every 50 ms, changing each capacitive sensor plate so that it can act as an excitation source, sensing element, and shield in turn, reducing noise reading from the sensor, sending sensor reading data from Arduino Nano to ESP32, receiving and parsing the data according to the data sent by the Arduino Nano, and turning on or off the fertigation system according to the data obtained. Based on the test results showed that the water content read on the capacitive sensor without planting media

Melon is a widely cultivated fruit because it only takes 60 days until harvest time. One of the biggest threats to melon farmers is crop failure. Melon cultivation in a greenhouse is one solution to overcome this problem. One of the parameters monitored is the water content in the planting media. A non-invasive capacitive sensor is used to read the soil moisture value evenly. This capacitive sensor works like a capacitor, with the planting media as a dielectric material that is placed between the electrode plates. The sensor requires a signal conditioning circuit to convert the capacitance value of the sensor into a DC voltage so that it can be read by the ADC. this circuit has specifications such as: the ability to generate an output in the form of DC voltage, ability to generate different output value for the different condition of planting media, and ability to be read by microcontroller's ADC. The test is carried out on the Signal Conditioning Circuit which consists of: De Sauty bridge circuit, full-wave rectifier circuit, and operational amplifier circuit. The results s
