However, automatic blink detection is challenging due to its blink rate. This paper proposes a real-time method for detecting eye blinks in a video series. The method is based on automatic facial landmark detection trained on real-world datasets and demonstrates robustness against various environmental factors, including lighting conditions, facial emotions, and head position. The proposed algorithm calculates the position of facial landmarks, extracts scalar values using the Eye Aspect Ratio (EAR), and characterises eye proximity in each frame. For each video frame, the proposed method calculates the location of the facial landmark and extracts the vertical distance between the eyelids using the position of the facial landmark. Blinks are detected by using the EAR threshold value and recognising the pattern of EAR values in a short temporal window. According to the results from a common data set, it is shown that the proposed approach is more efficient than state-of-the-art techniques.","PeriodicalId":412803,"journal":{"name":"ZERO: Jurnal Sains, Matematika dan Terapan","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123740130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The quality requirements for palm oil used as a raw material in the food industry and the non-food industry are distinct. Consequently, authenticity, purity, freshness, and other aspects need to be given more thought. The crude palm oil content is still selected manually in the processing section. It is challenging to process this, and it does not completely rule out the possibility of assessment errors. Based on the assessment above, determining high-quality oil frequently presents challenges, particularly when it comes to valuing crude oil levels or aspects in accordance with quality and standards. In light of these issues, a system that can assist in determining the level and quality of raw oil is required. Consequently, developing a method for determining the content of crude palm oil using Fuzzy MultiAttributeDecision Making and Simple Additive Weighting methods.

CV. Horizon Sibolga Group is a company that provides raw fish for sale to fish processing consumers. The company is located at Gatot Subroto street Number. 108 Pondok Batu Sarudik, Central Tapanuli Regency, North Sumatra Province. In this study, the North West Corner method will be used to find an initial feasible solution, and the Modified Distribution method will be used as an optimization test. If the test results show an optimal solution, then the allocation has been optimal and can be said to have reached the most profitable value. These results were obtained using Matlab software. Before the calculation, the company incurs distribution costs for a year of Rp. 963,000,000. From the research results, the total cost obtained after using the North West Corner method as an initial feasible solution is Rp. 928,831,000, and after using the Modified Distribution method as an optimization test, the total distribution cost is Rp. 923,058,000.

The authors applied a quantitative descriptive approach to companies listed on the Indonesia Stock Exchange in the Pulp & Paper sector for this study. According to the Correlation and Regression tables, all of the variables ROA, ROE, DER, and BVS have an effect on stock prices, but the stock session obtained on the variables ROA, ROE, and DER has a very significant effect on stock prices but has no significant effect on stock prices on the BVS variable.
