Abstract

Audio forensics is a method used to analyze sound or audio recordings. Voice or audio recording is one of the digital evidence that is easy to manipulate. One way to manipulate sound is to use magic call. Magic call has several levels of character voices that can be used such as cartoon, children, male and female voices. The analysis of the original voice recording with the magic voice recording is done by comparing the magic call sound and the voice with the original voice recording. The purpose of this study was to determine the voice recording produced by magic call from the magic call applications. As for the method used in this research is audio forensics, research on magic call sound using audio has never been done before. The results of this study indicate that the analysis of magic call sound recordings can be done using formant analysis and spectrograms, while pitch analysis on magic call voice recordings cannot be used. The formant and spectrogram values on magical voice recordings can still be searched because the original voice recordings have characteristics that are still attached to the magic recording calls.

Abstract

Information Technology (IT) services are services developed by service provider organizations for customers. Service provider organizations in implementing IT services have a goal to ensure IT systems remain in good condition to avoid incidents. Incidents are unexpected interruptions and reductions in the quality of IT services. Therefore, when an incident occurs in IT services, it is necessary to recover as quickly as possible or it is called incident management. Incident management is very important for service provider organizations, because if incidents are not managed and analyzed carefully then these incidents will recur. On this basis, a study was conducted to develop an IT service incident management analysis model based on the Information Technology Infrastructure Library (ITIL) V3 which aims to serve as a guide in analyzing and making recommendations for incident management. This model uses case studies in the PPTI section at Dinamika University. This model produces three stages including the incident data collection stage which produces IT service incident data. The incident management analysis stage produces a gap analysis, while the recommendation stage produces recommendations for improvement.

Abstract

Investing in the stock market is an important and fascinating endeavor, especially when we observe significant increases in certain stocks. Currently, Netflix stock is one of the rising stars and sought after by investors. However, along with the potential for high profits, there are certainly risks of losses that need to be anticipated. To mitigate these risks, an investor must make predictions about future stock prices. One method that can be used is data mining, a data processing technique used to discover patterns in data. In this study, data mining was conducted using the multiple regression algorithm to predict the future price of Netflix stock. Python and Jupyter Notebook were used as tools to process the data, which was collected from January 4, 2010, to March 30, 2023, totaling 3334 data points. After data processing, the model yielded a score of 0.99%, indicating a highly reliable model. Additionally, evaluation using RMSE resulted in a value of 3.73, and MAE had a value of 2.80, both derived from 1334 testing data points. With accurate prediction results and the evaluation conducted, an investor can use these findings as a reference when deciding whether to buy or sell Netflix stock.

Abstract

Kartu Indonesia Pintar (KIP) scholarship program at Ahmad Dahlan University includes a monitoring and evaluation internal process conducted at the end of each semester to monitor scholarship recipients. This allows for an assessment of their eligibility to receive the scholarship in the upcoming semester. The current manual MONEVIN process results in a time-consuming and less objective eligibility analysis. This eligibility determination system is needed, utilizing data mining techniques based on previous KIP scholarship recipient data to make predictions. Naïve Bayes algorithm, a data mining technique employing mathematical probability calculations, is utilized. The process begins with preprocessing, followed by data mining, evaluation, system implementation, and testing using System Usability Scale. The research uses a dataset of 270 student records, employing a 9-fold cross-validation process to split the data. Implemented model is integrated into a website-based system accessible to Biro Kemahasiswaan dan Alumni (BIMAWA). Model testing employs the Confusion Matrix technique, resulting in an accuracy score of 0.985, precision of 0.987, recall of 0.985, and an F-score of 0.985, indicating a favorable classification outcome. The system's eligibility assessment is further tested using the SUS, yielding a score of 90. Therefore, it can be concluded that the developed system is suitable for use.

Abstract

The increased use of laptops and smartphones during the COVID-19 pandemic has led to an increase in the number of people suffering from nearsightedness. Convolutional Neural Network (CNN) is a class of deep learning that is capable of recognizing images and classifying images. Convolutional Neural Network is a technique inspired by the way mammals (humans) generate vision. CNN can be used to help nearsighted people detect or see objects in the house. With the CNN algorithm, this algorithm will be implemented to detect objects in the house to help people with myopic eyes. The number of epochs is varied in the dataset training process using Yolov5 which is included in the Convolutional Neural Network algorithm. The training dataset results show that the highest accuracy is 95%, which is obtained through mAp (mean Average Precision) calculation. The training process was carried out using a batch size of 16 and running training for 100 epochs. Different from previous research, this research implements the CNN algorithm to detect objects in the house to help people with nearsighted eyes.
