PERANCANGAN ULANG TATA LETAK FASILITAS PRODUKSI DI PT OSI ELECTRONICS

2024-07-14T14:11:45+00:00

Presently, the facility layout at PT OSI Electronics Automotive Division is facing challenges. There is a significant distance between work stations, resulting in a longer material transfer distance and increased time for moving goods between work units. The objective of the performed research is to expedite the transfer of materials and propose recommendations for enhancing the layout of the firm's facilities. This will enable the company to decrease material handling expenses and minimise the distance required for material transfer. The stages conducted in this investigation encompass: Gathering data on the spatial separation of production lines, the quantity of workstations, and the dimensions of each production line. The acquired data was subsequently subjected to the Blocplan methodology for processing, followed by an examination of the optimisation outcomes, calculations, discussions, and ultimately drawing conclusions to determine the ultimate layout design. The most optimal plan for achieving efficiency and smoothness in the production process is layout 2, which is derived from software processing. Proposed schedule. The current configuration has a material handling distance of 68.46 metres, significantly shorter than the original layout's distance of 185.5 metres. Consequently, the overall distance for moving materials is reduced by 117.04 metres. The daily material handling cost for this proposed plan is IDR 1,288,760, which is lower than the material handling cost per metre in the initial layout, which was IDR 3,492,038. Consequently, the corporation can reduce its daily material handling expenses by IDR 2,203,278.

PERANCANGAN SISTEM DETEKSI PLAT KENDARAAN BERMOTOR MENGGUNAKAN OPENCV BERBASIS WEB

2024-07-14T14:13:10+00:00

This research aims to design a motor vehicle license plate detection system using web-based OpenCV, applied in the Sandona residential complex, Batam. This system replaces access cards for entry, enhancing security by automatically detecting registered vehicle license plates. If registered, the gate opens automatically. The methodology includes preliminary studies, literature review, preparation of tools and materials, design, as well as testing and analysis. The system uses NodeMCU ESP8266, a webcam, a servo motor, an ultrasonic sensor, and software developed with Python and OpenCV for image processing. The detection process involves capturing images of license plates, processing the images to extract numbers, and matching them with a database for validation. Testing results show an accuracy rate of 75% under optimal conditions. Accuracy is influenced by the position of the license plate, which must be upright and straight to the camera, as well as adequate lighting conditions. Under ideal conditions, the system works well and can improve access efficiency and security in the Sandona residential complex.

PREDIKSI PENYAKIT DIABETES MENGGUNAKAN ALGORITMA REGRESI LOGISTIK

2024-07-15T05:54:33+00:00

The annual count of individuals afflicted with diabetes is rising. As to a survey carried out by the International Diabetes Federation (IDF), the global diabetes population is approximated to be 537 million by 2021, and this number is projected to increase further to exceed 780 million by 2045. The study's primary goal is to diagnose and forecast whether or not a patient has diabetes. The approach makes use of logistic regression, a statistical tool for modelling individual classifications of diabetes presence or absence. According to the diabetes risk prediction results, 43% of respondents gave consideration to the condition. Consequently, it has been demonstrated that normalisation enhances the accuracy of diabetes risk prediction using logistic regression methods. Based on the variables included, it is anticipated that the predictions made by this model will serve as a guide for the general public in understanding healthy living and diabetes prevention.

2024-07-12T01:51:10+00:00

Jesindo Mitra Prakarsa stores in Batam City include stores that offer a range of toys for kids. Lack of information about which items clients buy frequently or infrequently leads to an overabundance of inventory, which is a common issue for the store selling toys. Therefore, a projection that makes use of data or historical sales information is needed to assist the store in stocking the goods. The goal of this study is to use the K-Nearest Neighbor algorithm to predict the sales of the most popular toys among kids in Jesindo Partners Prakarsa stores. Data will be gathered through observation techniques, in-store interviews, and literature reviews relevant to the study's subjects. In order to forecast sales for the following month, the author used the Euclidean Distance formula with a value of k=3 and RapidMiner software to predict sales of the best-selling product, Tricycle Happy. The formula had a target of seven products, but it was predicted to sell as many as six. Based on the results of RMSE testing, which showed a value achieved close to zero at 2.035 +/- 0.000 means, the author's algorithm matched or was effectively applied to this study.
