One of ways to increase the success of hatching eggs is by selecting and separating the eggs embryonated (fertile) with eggs are not embryonated (infertile) by way of observation (candling). This system utilizes digital image processing as an identification process. By this system, it is expected that the identification results will be more accurate results than conventional monitoring, so as to increase the results of hatching. This system utilizes a flashlight as a medium, so that the egg's internal condition can be seen which then takes pictures by the webcam. After that the digital image processing is done by converting the original image (RGB) to binary image by providing a thresholding value (T), the T value is very influential in the next image processing, opening and closing, thinning the image (thinning), and contour detection. Then from the final process of contour detection produces the number of detection of blood vessels that are considered as embryos as a determinant of the outcome category of identification. From the experiments carried out the percentage of conformity between the original condition of the egg with the results obtained in the system that is 88.88%, in determining the yield category (fertile/infertile) with an error of 11.12%. For the suitability of the estimated percentage of hatchlings themselves have a success of 61.11% with an error of 38.89%. These results are influenced by many factors like the condition of the eggs and supporting devices in the system.

The development of communication networks is very useful in daily activities such as wireless data communication, monitoring and system security. In this case, a wireless sensor network technology is known, which is very suitable when applied to a system with a large number of nodes and spread over a large enough area at a low cost. This wireless sensor network is a wireless communication network that supports communication between sensor nodes in a considerable distance by placing several sensors in an area. Generally, this Wsn consists of a sensor node and a server node in the form of a personal computer. The data from the reading of the CO gas value will be sent directly from the sensor node to the node server. This device is built using the nRF24L01 module and the CO gas sensor using the MQ-7 sensor. This wireless sensor network communication system is built using multihop. From the activities it can be concluded that the success of sending data is influenced by the distance and number of nodes working on a topology, with the amount of data sent which is influenced by long distances and the large number of nodes, not all data is successfully received because of the large number of data collisions from each node.

Vannamei shrimp is a species of shrimp that has high economic value. In the process of trading vaname shrimp, there are different price classes. Determination of the price class of vaname shrimp is based on the size of the shrimp. But in the post-harvest process, the sorting of vaname shrimp is still done manually, namely by placing the white shrimp on a flat table and then separating it by size so that it takes a long time and the level of accuracy of the sorting process also becomes imprecise, as is done by cultivating in the coastal area of Madura, this is due to the limitations of available shrimp post-harvest processing equipment. In addition, the limited supply of electrical energy for the coastal area of Madura is also another factor that hinders the post-harvest process of vanname shrimp. The purpose of this study is to design and create a vannamei shrimp sorting system based on image processing. In processing this shrimp image using the Background Subtraction method. The Background Subtraction method is used as a separator between the object and the background. The sorting process is based on the size detection of shrimp by using the blob detection algorithm. BLOB (Binary Large Object) detection is an image segmentation method based on region growing. The goal is to analyze textures specifically and accurately. Because blob detection distinguishes colors that have thin gradations. Based on the tests that have been carried out, the average accuracy of the system in sorting vannamei shrimp is in the range of 90%.

Nasi merupakan makanan pokok penduduk Indonesia. Komoditas utama dari produksi nasi adalah petani padi. Saat ini banyak petani padi mengeluh karena hasil panen padi yang kurang maksimal, hal tersebut dikarenakan banyaknya serangan hama padi terutama tikus dan burung. Untuk mengatasi hama tersebut biasanya petani menggunakan racun tikus, pematik tikus dan kawat yang dialiri arus listrik yang diletakan mengelilingi sawah, hal tersebut tentu sangat bahaya dan sangat berdampak pada ekosistem sawah. Dengan perkembangan teknologi yang maju saat ini memungkinkan untuk membangun suatu sistem yang mampu mengantisipasi dan meminimalisir serangan hama padi. Salah satunya adalah menggunakan gelombang ultrasonik sebagai pengusir tikus dan pergerakan orang-orangan sawah sebagai pengusir burung. Karena tikus memiliki kemampuan pendengaran yang sensitif sehingga tikus terasa terganggu saat mendengar suara gelombang ultrasonik dengan frekuensi tertentu. Begitu juga burung, burung pemakan padi akan merasa terganggu ketika ada gerakan mendadak di sekitarnya. Tujuan yang ingin dicapai pada penelitian ini adalah dapat mempermudah pekerjaan petani untuk menjaga sawahnya dan juga untuk memaksimalkan hasil panen padi. Metode yang digunakan pada penelitian ini adalah dengan cara observasi secara langsung menggunakan panel surya sebagai sumber energi dan sensor cahaya sebagai inputan sistem dengan duat outputan yaitu speaker untuk mengeluarkan suara dan motor servo untuk gerakan orang-orangan sawah yang nyala bergantian secara otomatis. Setelah dilakukanya penelitian ini dihasilkan tikus merasa pendengaranya terganggu dengan rentan frekuensi 5-6 kHz dan motor servo mampu mengusir burung dengan rata-rata tingkat keberhasilan mencapai 80 %.

Carbon brush mempunyai peranan penting dalam dunia industri, akan tetapi masih terdapat sejumlah orang yang masih tidak mengerti cara kerja dari carbon brush tersebut dan tidak mengetahui keadaan benda tersebut dalam keadaan baik atau sudah rusak terutama oleh pekerja. Kelemahan pada saat troubleshooting menyebabkan para pekerja hanya menerka-nerka saja untuk kerusakan yang dialami, hal itu dapat mengakibatkan putusnya serabut carbon brush sehingga motor akan bekerja lebih berat dengan sisa carbon brush yang ada. Maka dari permasalah tersebut dibuatlah sebuah alat untuk memantau kinerja carbon brush itu sendiri. Yakni “rancang bangun monitoring sensor carbon brush untuk penulangan pada PT.WIKA BETON” yaitu penerapan sensor suhu untuk mendeteksi suhu pada setiap carbon brush. Penelitian yang dilakukan yakni menggunakan sensor suhu DHT11 yanki Carbon brush yang terdeteksi oleh sensor DHT11 akan mengirimkan data pada room control melalui ENC18J60 yang dilanjutkan dengan router data yang terdeteksi oleh sensor akan diproses dan akan menampilakn kondisinya pada GUI yang berada di room control, apabila suhu yang terdeteksi tidak melebihi dari 40°C kan terdeteksi motor dalam keadaan “normal” akan tetapi jika melebihi 40°C maka panel GUI akan menampilkan “overheat” yang akan mengaktifkan modul relay untuk mematikan mesin. Hasil dari pembacaan suhu akan disimpan dalam Microsoft acces yang digunakan sebagai arsip pabrik. Dari hasil penelitian ini menunjukkan bahwa system berjalan dengan baik. System dapat bertahan selam 24 jam selama masa kerja yakni 3 kali pergantian shift. Data yang dikirimkan real time dan sesuai dengan data yang ada dilapangan.

Low torque low owned by PMSM (Permanent Magnet Synchronous Machine) required an excellent control model. PMSM uses the principle of faraday's law by rotating magnets in the coil by using other energy sources. When a magnet moves in a coil or vice versa. The engine rotation will change the magnetic force flux on the coil and penetrate perpendicularly to the coil so that a potential difference arises between the ends of the coil. The potential difference is caused by changes in magnetic flux. in order to get the best control method, a good speed control model is needed. In this study comparing PMSM speed control using PID, Fuzzy Logic Controller (LFC), and Adaptive Neuro-Fuzzy Inference System (ANFIS). The simulation results show that the best model on the ANFIS controller that is closest to Speed Reff (300 rpm) is that ANFIS obtains the rotational profile with the smallest undershot, the fastest steady state, the best output current profile, the best torque profile, and the best voltage profile. The results of this study will be followed by the use of other Artificial Intelligence.

Often electronic equipment is damaged due to a sudden power outage. This often happens due to uncertain natural conditions, forcing PLN to carry out maintenance on its electricity distribution equipment. In addition, many electrical equipment can be damaged by sudden power outages. To be able to overcome this, people usually use generator to overcome supply failures manually. Based on this background, the author created an Automatic Transfer Switch (ATS) – Automatic Main Faillure (AMF) based on the STM32F103C8T6 microcontroller which is applied to generators when there is a power outage. The ATS – AMF device is made using Relays, PZEM004T Voltage Sensors, magnetic contactors, Miniature Circuit Breakers, stepdown circuits, LCD TFT and STM32F103C8T6 as control systems. This system uses the Fault Tolerance method so that the system can continue to run even if there is damage to the main battery by adding a backup battery as a backup. The results of this study, the Automatic Transfer Switch (ATS) circuit found that the average time needed for the generator to start is 2.5 seconds and the time needed for the generator to produce a stable voltage is 5.7 seconds, thus this time is used as the author's reference in determining the right time to switch the load on the microcontroller so that the load is not damaged due to unstable generator voltage. Whereas in the Automatic Main Failure (AMF) it was found that the Stepdown circuit used to detect whether or not PLN electricity was very responsive because the stepdown circuit was installed in parallel at the PLN source and can be proven by the results in the Arduino application.
