Abstract

Social anxiety disorder is a mental health disorder characterized by a fear of being watched, judged, or embarrassed by others. Anyone can actually experience fear or anxiety when interacting with other people. But for sufferers, this fear is experienced excessively and gradually over time. As a result, this condition affects interaction with other people, productivity at work, or achievement at school. For this reason, we need a system that can carry out psychological tests for social anxiety disorder, which are dominated by sufferers with an age range of 10-17 years and even more, sufferers who have anxiety and are afraid to tell what they are experiencing can use this application before deciding to consult a psychologist. . The application of the Dempster Shafer Method in this application provides accurate results on the percentage level of confidence in social anxiety disorder by transferring expert (psychological) knowledge into an Android-based application, the system will be said to be successful if it shows the same or close percentage. Implemented into Android-based software and the application is dynamically displayed and user friendly.

Abstract

PT.XYZ is a palm oil company currently implementing the Accurate data processing system to manage data at its factory. This system is utilized for weighing incoming palm fruit, processing palm fruit within the factory, and generating various reports. However, during the implementation process, the system has encountered several threats that have had an impact on the company. These threats include connection errors, human errors, and server downtime. To address these issues, a threat risk analysis is necessary to minimize the likelihood of similar problems occurring in the future. In this study, the OCTAVE-S method is employed as it offers solutions for managing other threats. The risk analysis results indicate that there are six security practices that pose a high risk to the company's system security. These practices are IT Security Monitoring and Audit, Authorization and Authentication, Vulnerability Management, Encryption, Security Planning and Architecture, and Incident Management. Based on these findings, it is recommended that the company conducts a review of its security practices to prevent the emergence of new risks that may affect its business processes.

Abstract

People often find it difficult to cope with the accumulation of household waste that includes furniture, clothes and other items. This accumulation of household waste does not only affect one house but also affects neighboring houses. Piles of unused items continue to accumulate in homes and other places, resulting in problems caused by inconvenience due to the large number of new items. With these problems, an application for buying and selling used goods was developed for people who want to sell or buy used goods. This research uses the Waterfall method as a software development method. This application is made by integrating the responsibilities of sellers and buyers simultaneously, resulting in one account that can buy and sell at the same time. With this application, it is hoped that the community can be helped in finding used products or goods that are still suitable for use.

Abstract

Attack trees can be formulated based on the steps of exploitation that occur in web applications. The aim of this research is to understand the relationship between attack trees and exploitation characteristics based on time and skill level metrics. The platform for exploitation testing uses DVWA and is organized into an attack tree. The attack tree is structured with both protected and unprotected WAF conditions. The attack tree is organized based on five vulnerabilities: SQL Injection, XSS (Reflected), Command injection, CSRF, and Brute force. The analysis results with the unprotected WAF condition conclude that the XSS (Reflected) attack tree ranks first with a score of 131.92. The SQL Injection attack tree ranks last with a score of 1727.56. Meanwhile, with the WAF, the SQL Injection attack tree ranks first with a score of 54. The Brute force attack tree ranks last with a score of 319.51. Thus, this relationship can be used for ranking attack trees based on time and skill level metrics. Further research can involve detailing the steps of exploitation using CVSS scores as a skill level calculation and measuring parameters using IDS as one of the firewall features.

Abstract

Traditional markets face significant challenges from the growth of modern markets and e-commerce, which can lead to reduced attractiveness, loss of competitiveness and decreased sales. Traditional markets have a key role in economic, social and cultural sustainability. Therefore, the preservation and transformation of this market is very important to support the economy, promote local products and maintain cultural heritage. This research aims to improve the economy of traditional markets by implementing collaborative filtering technology, which makes it easier for consumers to find the desired products. The Horas Market in Pematang Siantar City is the object of research. Collaborative filtering is a technique that uses user data to recommend products based on similarities to other users. The dataset includes the opinions of 2,114 consumers who purchased products from 10 kiosks, totalling 97 products and 5,948 product ratings. Test results using the RSME metric with 100 epochs show a value of 0.1832 on the training data and 0.1908 on the test data. These results show the suitability of the Matrix Factorization-based collaborative filtering method as an application recommendation system at the Horas Market. In the context of traditional markets, this technology can increase sales by recommending relevant products to customers, encouraging the economic growth of traditional markets. However, it is necessary to understand the long-term implications for local communities and the economy as the next step in this research.

Abstract

Examination of the nutritional status of toddlers is one way to monitor and identify toddlers who are at risk of experiencing nutritional problems. Implementation of the method in predicting nutritional status using relevant parameters. The Decision Tree method is used as a predictive model, using a dataset with parameters such as age, sex, height, weight, and nutritional status as labels. At the mining stage, data processing starts from preprocessing, namely the cleansing process to clean up incorrect data and data transformation to change the data type so that it is easy to process during the classification process. Furthermore, the Decision Tree model will be trained, tested and measured based on accuracy. The model is described in the form of a decision tree so that it can be used as a rule in system implementation. The implementation results provide accurate predictions with an accuracy value of 92.73%. The prediction system is designed to assist health workers in supporting decisions on predicting the nutritional status of children under five, as well as facilitating the community to carry out independent checks. This prediction can help identify toddlers at risk of nutritional disorders so that early intervention steps can be taken appropriately..
