Abstract

To minimize production down time that caused by equipment damage, it is necessary to have sufficient spare part availability. But sometimes this is hard to fulfill because of the price of spare parts and there are any specifications that are difficult to find. One of the equipment that has a vital role in steel manufacturing process is a gas valve actuator that has a function to regulate the flow of gas volume used in the billet reheating process. Most actuator problems are caused by the control circuit, while the mechanical and actuating devices can still work normally. Replacing the actuator unit will require a large cost, as well as a relatively long response time. From these problems, a control system is designed that can be applied to the actuator units that are already available by utilizing Arduino UNO as a processor, to reduce down time due to equipment damage. The method applied to this tool is to compare the input signal value with the actual gas valve opening position from the potentiometer. Based on the results of data collection shows this control system has an average error value of 0.7075%. The results of the tests carried out show that the Arduino UNO-based control system can operate the actuator unit effectively, to be used in the billet reheating process.

Abstract

Rice milling into rice, (Rice Milling Unit, RMU) is needed to process the harvested grain into rice. In determining the location, the consideration of road access to consumers is still used and it is often far from the rice fields, the source of the grain material to be milled. This paper aims to analyze the ideal location with the consideration of being in a rice field cluster and the area of the rice field, so that it can accommodate crop yields around the cluster, namely the location of the spatial coordinates and the area (hectare). Primary data was obtained by the author from the Department of Agriculture of Malang Regency and the data was processed as input for analysis. Analysis of determining the location of the center of the rice field cluster using the Weighted K-Means Clustering method by comparing several alternative cluster points (K) and the area of rice fields, testing the variation of K is, K = 5, 6, 7 and 8. Optimal test results at K = 7. Calculations using the R language. The test results obtained that the cluster center suggested 7 clusters to accommodate the rice harvest in 7 regions, namely in the west, north (1), middle (2), south (3), east (1) and west (1 ) . Evaluation of the location of the existing RMU, there are 5 locations, so that for the next planning, you can add 2 more clusters to build the RMU and accommodate a more even rice harvest.

Abstract

The medical image system in the form of digital examination results using Computed Radiography (CR) needs to be analyzed, this can be done by knowing the quality of the image contrast resolution and the quality of its spatial resolution. This study conducted a comparative test between two methods of analyzing contrast resolution of medical images. Image quality on Computed Radiography can be determined using contrast resolution analysis, namely calculating the CNR value and PSNR value. The study was carried out using a phantom to represent the density of the bone. The voltages used are 50 kV, 60 kV, 70 kV and 81 kV, respectively. With each voltage, the tube current and exposure time (mAs) were varied 1.6 mAs, 2 mAs, 4 mAs, 8 mAs, 16 mAs, and 32 mAs. The higher the CNR value obtained, the better the image quality. While the PSNR value to get the optimal quality of medical image contrast, the current-time variation of 4 mAs and 16 mAs must be used. Due to the time-current variation, a high PSNR value is obtained, which indicates that the noise of the medical image is getting smaller so that a good contrast quality of the medical image is obtained. Both of these methods can be used to test the suitability of X-ray device, especially for quality control of medical images
