Abstract

The presence or evidence of attendance is crucial in monitoring the presence of every individual working in a particular field. Developing an employee attendance system using fingerprints can expedite the processing of data of employees who have or have not attended. One brand of machine used as a fingerprint attendance tool is Fingerspot Flexcode. The data obtained from the machine comes in the form of bitmap images that are converted into strings using encoding. Although the resulting string sequences are different, there is a possibility of similarity in fingerprint data among employees because the system cannot distinguish data precisely. Therefore, the comparison between the Levenshtein Distance and Hamming Distance methods is used to determine which method has the highest accuracy in processing the system's calculation. The method with the highest accuracy will determine the level of compatibility of the method with the tested tool. For example, 6 fingerprint data are taken from each of the 7 different employees, resulting in a total of 42 data as test data. The calculation results show that the accuracy of the Levenshtein Distance method is 80,76 % with a precision of 46,43 %, while the Hamming Distance method is 78,34 % with a precision of 30,50 % in processing string similarity in fingerprint data. Based on these results, it can be concluded that the Levenshtein Distance method is better in calculating similarity in fingerprint data compared to the Hamming Distance method because it has a higher level of accuracy and precision compared to the Hamming Distance method.

Abstract

Consuming medicine on time is important for people who are sick. Medicine that prescribed by a doctor or pharmacist have various kind of rules, for example some medicine must be taken 3 times a day, 2 times a day, and 1 time a day, then there are rules after eating or before eating. Patients treated in the hospital are supervised by nurses, doctors, and receive more supervision from the hospital, but what if the patient is outpatient and the patient is an elderly person. With the presence of IoT technology that is not too expensive, a smart medicine box was made to be used to remind outpatients to take medicine which implements IoT technology and the android application used to manage the pillbox. The medicine box can remind patients to take medicine with the alarm module that is in the smart medicine box. System Usability Scale (SUS) is used to measure the success of the application. Smart medicine box is tested directly with data created to test the existing system. The result of testing the smart medicine box with existing data show that for each existing case, the smart medicine box system runs as it should. Application test results from all respondents received an average score of SUS 73,75. The score results show that the application can be accepted, get a grade scale worth B, and get good grades.

Abstract

Designing an Information System for Processing Police Report Data at the Women and Children Protection Unit of the North Gorontalo Police, so that it can assist officers in collecting large numbers of reports, and can present reports quickly. The method used is the Research and Development (R&D) method. The system is made with PHP and HTML programming. The database used is the MySql language. For modeling using UML (Unified Modeling Language). For testing this system using white box and black box testing where with this test the correct graph flow is obtained as a sample the researcher tests the Input Data flowchart Report on the admin system obtained is the value of region (R) = 3, Independent path = 3, and Cyclomatic Complexity (CC) = 3.

Abstract

Developments in the economic sector so far have had quite rapid consequences in the business world, this has resulted in differences in sales at the market level. The market itself is a meeting place for buyers and sellers to make buying and selling transactions of goods or services. Tulangan Market is a traditional market located in the District of Tulangan, Sidoarjo Regency, East Java Province. In the Reinforcement Market there are several types of sellers such as retail traders, wholesalers and kiosks which are scattered in almost all corners of the market. The Tulangan market is also not much different from markets in general which sell daily needs such as food ingredients in the form of fish, fruit, vegetables, eggs, meat, cloth, electronic goods, services, etc. Besides that, it also sells traditional cakes and other Indonesian food. Not all traders in the Reinforcement Market can carry out the buying and selling process freely, especially during erratic rainfall. This creates problems in the sales process factors for traders. After knowing this problem, the author wishes to help traders who do not have their own trading area so that they can run their business stably and smoothly. With the current rapid world of technology, the authors hope that traders can use web pages that are familiar to many people to alleviate their problems through the "Website-Based Market Information System Case Study of the Sidoarjo Tulangan Market".

Abstract

Within the field of digital image processing applications, observed images frequently exposed to noise corruption stemming from image acquisition or transmission processes. This noise degradation reduces image quality and yields unfavorable outcomes in subsequent processing stages (e.g., segmentation, pattern recognition, and enhancement). Consequently, the mitigation of noise in images assumes paramount importance in the domain of image processing. This study introduces an algorithm centered around fuzzy logic for removing impulse noise from color images. The efficiency of the proposed algorithms is assessed by comparing their performance against various noise reduction methods. Objective metrics, namely peak signal-to-noise ratio and mean square error, substantiate that the proposed algorithms yield commendable outcomes in noise reduction and the preservation of intricate image details across a wide spectrum of noise densities
