“…Vibration occurs due to the presence of excitation forces. Almost all moving machines generate vibration, although their intensity may be very small [13]. The data collected by the sensor on the first stack using 100 RPM is shown in Figure 7, and the results show that the lowest vibration point is at 1.53 Hz and the highest point is at 1.80 Hz.…”

Based on data from Badan Pusat Statistik (BPS) in 2017-2018, the tomato productivity in Indonesia has seen a year-on-year increase of 10% and 19%. However, during the transportation process of agricultural commodities, excessive vibration can lead to damage of tomato commodities. Therefore, the purpose of this study is to develop an environmental data recording device using Arduino technology, and to assess its performance by simulating vibration during transport. The aim is to ensure proper handling and storage of tomato commodities in the distribution process. The designs used are programming designs, functional designs, and structural designs. The results showed that the design of an arduino-based environmental data recording instrument, calibration results between the DHT22 sensor (temperature) and a digital hygrometer yielded a correlation equation value of y = 1.0475x – 1.5575, R2 for the DHT22 sensor was 0.9885, and for the calibration results between the vibration sensor and the vibrating table as a calibrator obtained a correlation equation value of y = 1.9471x-101.24, the calibration R2 value was 0.8088, the instrument accuracy performance test results were obtained by 80%. The stability test results of reading past the setting point, the control speed is 4.04 minutes, the result of the reliability coefficient value (r11) is 0.90. The reliability coefficient value from the stability test results is included in the very high reliability category, the system response at a setting point of 150 RPM takes 63 seconds and the system response at a setting point of 200 RPM takes 71 seconds. characteristics that occur in tomatoes during the transportation simulation process where at 100 RPM the test was carried out, the tomatoes experienced a collision and only a few were bruised due to the shock from the transportation simulation the tomatoes were damaged and collided between the tomatoes in the box, the greater the vibration received by the tomatoes on during the transportation simulation, the more tomatoes will experience physical damage.Test results on tomatoes with a degree of mechanical damage (bruises) due to vibration during transportation. In stack 1 100 RPM there was no damage to the fruit while the biggest bruising occurred in stack 3 with 200 RPM.

Telah dilakukan penelitian penerapan alat gammasilometer Cs-137 pada digester/preheater yang ditinjau dari pengukuran level chip dan ketinggian level berdasarkan perubahan speed discharges screw.. Dilanjutkan dengan proses preheating dengan dilakukan pemasakan serta pengukuran level chip ditinjau dari pemancaran sumber radioaktif ke receiver dan transmitter sehingga, sampai ke layar monitor operator. Seluruh proses yang dilakukan secara continue atau terus menerus. Hasil pengukuran level dan ketinggian didapatkan dari kalkulasi perhitungan PLC (Programmable Logic Controller). Hasil dari pengukuran ketinggian level terhadap perubahan speed discharge screw diperoleh bahwa semakin cepat speed discharge screw, maka akan semakin tinggi level chip pada preheater. Hal ini berarti, ketinggian level chip berbanding lurus terhadap speed discharge screw.
