<p>Penetasan telur saat ini tidak lagi dilakukan secara alami lewat pengeraman induk, tetapi menggunakan alat penetas telur. Alat penetas telur merupakan suatu alat yang digunakan untuk menghangatkan suhu pada telur ayam sebagai pengganti pengeraman induk ayam. Alat penetas telur yang ada pada saat ini kebanyakan menggunakan metode pengaturan secara manual yang memerlukan pengamatan terus menerus. Hal tersebut sangat tidak efisien. Maka dari itu pada penelitian dirancang alat penetas telur ayam kampung otomatis dengan metode PID (<em>Proportional Integral Derivative</em>) berbasis Energi<em> Hybrid</em>, system ini bekerja dengan cara merubah suhu ruang alat penetas secara otomatis berdasarkan setpoint yang ditentukan. Sistem pemanasan alat penetas telur ini menggunakan lampu yang dikontrol oleh <em>dimmer lighting control</em> serta terdapat rak penampung telur yang digerakan dengan motor servo agar sesuai dengan teori penetasan telur. Dengan menggunakan <em>Energy Hybrid</em>, maka alat penetas telur ayam tersebut dapat tetap menyalah walaupun listrik padam. Sehingga, waktu proses penetasan mencapai hasil yang maksimal. Set point suhu yang digunakan sebesar 38°C. Hasil yang diperoleh dari keseluruhan pengujian system penetasan telur otomatis mempunyai tingkat keberhasilan sebesar 54,5%.</p><p><strong>Kata kunci:</strong> Alat Penetas Telur, Telur Ayam Kampung, <em>Dimmer lighting control</em>, <em>Energy Hybrid</em>, PID.</p>
Abstrak – Selama ini kebanyakan robot penghindar halangan dibangun dengan menggunakan acuan dari beberapa sensor jarak yang diletakkan pada badan robot, kelemahan dari sistem ini adalah robot hanya dapat menghindari halangan tanpa mengetahui letak target berada. Pada penelitian ini dibangun sebuah robot penghindar halangan berbasis kamera dengan lensa 0,67x wide yang diletakkan 2 meter diatas arena, sehingga posisi robot, halangan dan target dapat diketahui secara real-time. Citra dari kamera akan diproses menggunakan laptop yang telah terinstall aplikasi CodeBlocks dengan pustaka OpenCV, outputnya berupa sebuah karakter perintah pergerakan motor DC yang dikirimkan pada robot melalui komunikasi bluetooth. Deteksi kontur digunakan untuk membedakan objek yang dipilih dengan gangguan disekitar. Dari hasil pengujian, sistem kalibrasi range warna HSV yang dikembangkan telah mampu menghasilkan range warna yang akurat untuk color filtering, menggunakan metode auto-click dan tunning-manual. Kalibrasi pengujian jarak sebenarnya berdasarkan jarak piksel menghasilkan trend grafik yang linier, sehingga persamaan liniernya dapat digunakan untuk konversi jarak piksel menjadi jarak sebenarnya dalam satuan centimeter. Hasil pengujian laju robot, sistem yang dibangun dapat membuat robot berjalan mendekati target dan menghindari halangan di depan robot, meskipun terkadang mengalami osilasi tapi robot mampu kembali stabil, ini dikarenakan sistem yang dibangun tidak menggunakan metode peredam osilasi seperti PID. Kata kunci – Robot Penghindar Halangan, Kamera, Deteksi Kontur.
Internet of Things technology in this research is utilized on solar power plant (Case Study: Electrical Engineering Department of Trunojoyo Madura University) as a battery power monitoring and load control system. All of these systems were built to make it easier for users to manage the power consumption while preventing battery damage so that lifetime can last longer and the use of PLTS than more optimal. All of these systems are designed to use several integrated components with their respective functions, including Raspberry as a data processing, smartphone as an interface, and sensors actuator as input-output. From the results of the monitoring accuracy test, the average error value is 1.56%. After ensuring the system has a high level of accuracy, The charge-discharge test is conducted in real-time for 7 days, which shows that the system works according to the research objectives as evidenced by the nothingness of power consumption exceeding the SOC standard limit battery used by 30%. Meanwhile, for the control system test, the wifi connection has the fastest average delay for 10,30 s, provider A 11,17 s, and provider B 12,60 s.
<p><em><em><em>Rice is the staple food of the Indonesian population. The main commodity of rice production is rice farmers. At present many rice farmers complain that rice yields are less than optimal, this is due to the many attacks of rice pests, especially rats and birds. To overcome these pests, farmers usually use rat poison, mouse burners and wires that are electrified which are placed around the rice fields, it is certainly very dangerous and very impacting on the rice field ecosystem. With the development of advanced technology now it is possible to build a system that is able to anticipate and minimize rice pest attacks. One of them is using ultrasonic waves as a mouse repellent and the movement of a scarecrow as a bird repellent. Because mice have sensitive hearing abilities so they feel disturbed when they hear the sound of ultrasonic waves with a certain frequency. Likewise birds, rice-eating birds will feel disturbed when there is a sudden movement around it. The objective to be achieved in this research is to facilitate the work of farmers to maintain their fields and also to maximize rice yields</em></em></em></p>
