Metoda mengamati warna urin sudah dilakukan sejak lama untuk melengkapi diagnosa penyakit yang diderita seorang pasien. Pengamatan dengan panca indra vision manusia dilakukan untuk meneliti dan menganalisa warna urin seseorang dan menghubungkannya dengan penyakit yang diderita pasien tersebut. Fungsi vision manusia dapat digantikan dengan sistem komputer yang dilengkapi dengan alat yang mampu mendeteksi warna seperti kamera maupun jenis sensor warna lainnya. Warna objek dapat dibedakan dengan menguraikan komponen warna objek tersebut berupa komponen warna dalam domain frekuensi maupun dalam domain spasial. Hal ini dimungkinkan karena setiap warna memiliki nilai panjang gelombang tertentu dan dituangkan dalam nilai frekuensi. Sensor warna TCS 3200 menghasilkan sinyal output dengan frekuensi yang berbeda berdasarkan warna yang discan oleh foto dioda pada sensor tersebut. pengenalan suatu objek ditandai dengan bentuk, warna dan variable lainnya dari objek tersebut. Ekstrak ciri dari suatu objek dapat dituangkan dalam bentuk pola data maupun histogram yang mencirikan warna objek tersebut. Penelitian ini bertujuan untuk membuat histogram dan pola data warna urin berdasarkan indikasi kondisi yang diderita seorang pasien. Sebagai acuan warna yang digunakan adalah warna dasar urinalisis hasil penelitian di Cleveland Clinic, di Ohio tahun 2013. Dari hasil penelitian telah didapatkan pola data dan histogram warna yang berbeda berdasarkan warna urin yang dideteksi. Diharapkan hasil penelitian ini dapat digunakan pada proses identifikasi penyakit melalui warna urin secara online.

Engine scanner unit is a tool used by mechanical power to know the condition of car engine combustion at the time of tune up process done.The level of elements and compounds that dominant in determining categories of combustion of gasoline fuel car engines through the levels of elements and compounds contained in exhaust emissions are Hydrocarbons (HC), Carbon Monoxide (CO), Carbon Dioxide (CO2) and Oxygen (O2). Complete combustion category produces maximum power, fuel efficiency and emission levels according to the threshold. This occurs when there is a balance of the amount of fuel, airflow and ignition in the engine combustion chamber. Elements and compounds contained in car exhaust emissions can be detected with sensors that are sensitive to elemental levels and these compounds are HC, CO, CO2, and O2 sensors. This study aims to display the data pattern category of combustion engine through exhaust emissions based on multi sensor detection processed with signal processing system in the form of Fast Fourier Transform (FFT) process. Furthermore, data pattern is performed in accordance with the category of combustion engine detected. The system is designed with embedded system using Field Programable Gate Array (FPGA) myRIO and LabVIEW programming. The results in the test displays the data pattern and the comparison test of the reference data pattern with the data pattern of the detection result. The comparison test result of data pattern similar to 87% complete engine combustion category and similar to incomplete combustion category 90%.

An analysis has been carried out to treat the meat grinder machine. The care of the meat grinder machine is important to help the production process of rendang suir craftsmen. Meat grinder machine consists of several components, namely the engine, electric motor, pulleys, V-belts, reservoirs, and spindle shaft. With the components above, this meat grinder machine is expected to work optimally with satisfactory results. The meat grinder machine treatment consists of repairing, repairing, total care. Canceled maintenance consists of recovery, lubrication, and periodic checks. Repair treatments include maintenance of the blade, bearing care, pulley care and belt. While total maintenance is carried out after the engine has been running long enough. The result of the treatment that has been done is a machine that can be run properly which can produce a maximum of 30 kg / hour

The main goal to be achieved is to be able to make an onion slicing machine so that it can answer the problem if the onion slicing is carried out in a larger capacity. The onion slicing machine is made to support the increase in the production of shallot slices, which are ready to be fried for the production of scallion onions in household industries. In a small scale, the work can be done manually with a knife or other simple cutting tool. Problems will arise if large quantities of sliced or cut production are available. In order to facilitate the community in processing shallots and learn about the problems, namely how to produce a shallot slicing machine with uniform slices results using different slope angles on the knife. the working principle of this machine is the Onion which has been peeled dry skin inserted into the funnel then the plate on the back of which has a knife, will rotate because it is driven by an electric motor. As a result of the rotation the onion will be sliced and the slice will fall down, and below it a container will be used as a cross section of the onion which has been finished sliced as a result
