Abstract

The range of patient age groups is the age category of the population based on their welfare group. Age group aims to look at certain welfare groups that are dominated by relatively productive age groups or dominated by non-productive age groups, for example, children or the elderly. There are several criteria used to calculate the decision support system, namely age range, type of activity, and number category. In this case the researcher wants to design and make a decision support system application using the comparison of the WP method and the topsis method which aims to determine the age group of patients who visit the most health centers. Researchers will conduct research at the Old Village Health Center with the title "Comparative Analysis of Decision Support Systems in the Range of Patient Age Groups in Health Centers Using Weight Product and Topsis Methods".

Abstract

The Images taken with a digital camera at night with minimal lighting will produce a dark image and it is difficultto recognize objects in it. The image results obtained appear black and the details in the image are not clearlyvisible. In such conditions, it is necessary to improve the image (image enhancement) which aims to get the imagedisplay with a better form of visualization. This study aims to examine the effect of dark images on the performanceof the High boost Filtering method and the Adaptive Histogram Equalization method in improving image quality,especially the types of dark images taken from smartphone cameras at night so that they can provide solutions inthe form of applications and information on how to improve image quality on dark images so that detailed imageinformation can be seen visually. The test results using three dark images in bitmap format (*.bmp) taken from asmartphone camera at night with different lighting affect the performance of the High boost Filtering and AdaptiveHistogram Equalization in improving image quality, meaning that it gets darker. Image object then the result isalso not good and vice versa. The best results use the High boost Filtering method. The High boost Filteringmethods produces an image histogram that is evenly distributed so that detailed image information can be seenvisually.

Abstract

Improving the security of cryptosystems is a challenge that attracts many researchers to propose and develop new cryptosystems to achieve cryptographic goals. In addition to implementing new cryptographic algorithms, the way that can be done is to modify, combine algorithms or even add other methods to improve existing cryptographic algorithms. Playfair Cipher is a cryptographic algorithm that has long been known and is still widely used and studied today. To optimize or strengthen the confidentiality of data from encryption (ciphertext) using the Playfair Cipher algorithm, research will be carried out by adding reverse operations and conversion into Morse code. This research produces a desktop-based application that can be used in optimizing the security of the encryption results of the Playfair Cipher cryptographic algorithm. From the test results on 10 data samples, it shows that the frequency of characters from the results of reverse and encryption (ciphertext) changes in value constantly along with the addition of the number of characters in the test text. However, after being converted into Morse code, it does not show any pattern of connection between the results of the Morse code conversion and plaintext. This proves that the encryption results after being converted into Morse code can increase (optimize) the security of the Playfair Cipher algorithm, because it will produce more random text and will not show patterns of connection between the results of the conversion into Morse code and the original text (plaintext).

Abstract

The new student selection process is very important to ensure the quality of prospective students accepted into universities. Harapan University considers various factors, such as high school majors (science, social sciences, or TKJ), academic test results, interviews, diplomas, and academic and extracurricular achievements. The manual approach that is still often used tends to be time-consuming, inefficient, and prone to errors. This study aims to develop a decision support system based on the Preference Selection Index (PSI) method to improve the effectiveness and efficiency of the selection process. The PSI method was chosen because of its ability to evaluate criteria directly without requiring weighting. The results of the study show that the PSI approach is able to produce the best candidate rankings based on predetermined criteria. This system offers a more organized, transparent, and accurate solution in the new student selection process.
