Design and Build a Vaname Shrimp Sorting System Based on Image Processing: Rancang Bangun Sistem Sortir udang Vaname Berbasis Image Processing
Full text linkVannamei 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%

One of the symptoms of cow disease that often occurs is caused by parasitic worm infection. To make sure the animal is healthy or not, it is determined from the results of laboratory tests through fiscal samples so that cow disease can be known accurately. However, limited laboratory facilities, especially in rural areas, make it difficult for farmers to identify this parasitic disease. The purpose of this study is to apply a digital microscope design as a tool to identify the type of parasitic worm eggs in cattle based on image processing using the Yolo V3 algorithm, so that it is hoped that it can assist farmers in detecting parasitic worms in livestock. In this study, a digital microscope was designed as a tool to identify the type of parasitic worm eggs in image processing cows. This detection system uses a digital microscope as an instrument to detect the presence of parasitic worms in the test sample. This digital microscope is equipped with a camera so that the detection of data from the reading process is directly connected to the data processing tool. In this study, a digital image processing mechanism with the Yolov3 method was used which functions as an identification of parasitic worms in cattle. This algorithm works with the principle of feature extraction which is used to distinguish the shape and texture of parasitic eggs by counting pixels with a certain value. Experiments have been carried out on 100 cow dung. The average accuracy of the system in identifying is 78.42% for parasites and 80.84% for non-parasite
Design of a backup voltage supply in a medium-voltage cubicle control panel circuit when a blackout occurs from PLN: Perancangan Suplai Tegangan Cadangan Pada Rangkaian Kontrol Panel Kubikel Tegangan Menengah Ketika Terjadi Pemadaman Dari PLN
Full text linkUninterruptible Power Supply (UPS) is an important component that is useful for temporarily storing electrical energy. This storage is done in the UPS battery itself, the capacity of each battery is different. Indirectly this UPS is also useful in order to avoid flickering when the electric current from the PLN goes out. This is done in order to avoid damage to the electronic device. In Angkasapura II Bandung as well, UPS is used to avoid flickering which causes damage and even crashes on the plane due to a communication failure between the Pilot and the AFL. Another obstacle is the cubicle control panel circuit. This happens because when there is a blackout from the PLN UPS, the active UPS does not back up this circuit, the bad thing that happens is that the electrical control at Angkasapura will stop because the cubicle control circuit does not receive electricity supply. From the results of this study resulted in a new circuit that can read-up power automatically with the existing UPS

The Effects of Damage to the Outer Race Bearing on the Efficiency of the Induction Motor Using Fast Fourier Transform (FFT) Method: Efek Kerusakan Outer Race Bearing Terhadap Efisiensi Motor Induksi Menggunakan Metode Fast Fourier Transform (FFT)
Full text linkBearing is an induction motor component that helps the rotor to move freely, in industrial applications it is important to maintain bearing performance in induction motors. In its use, bearing damage is one of the biggest types of damage that is often found in induction motors. Bearing damage can lead to increased vibration, increased noise, increased working temperature, and decreased efficiency. Efficiency reduction can be used as information on the condition of the motor so that this information can be used to detect damage before more serious damage occurs. This research discusses the stator current analysis method and the efficiency of damage to the motor through two harmonic amplitude ratios equipped with the fast Fourier transform (FFT) algorithm in detecting damage to the outer race bearing. It is hoped that this efficiency can be used as an evaluation of the extent to which motor energy waste occurs before more severe damage. The efficiency results on the damage to the outer race bearing using the FFT method get the highest efficiency value of 1.47 and the lowest value of 0.66
