Abstract

The government assistance program is financial support provided to the community with the aim of helping to improve the quality of life and welfare of almost all provinces in Indonesia including Central Java Province, especially in Ajibarang District, Banyumas Regency. This program aims to overcome the gap between the upper middle economic community and the lower middle economic community. However, the implementation of aid so far has not been even and fair, so it has not achieved its goal of helping people who really need it. In the process of providing assistance, it is important to have a strong basic foundation in determination and decision making. The program must ensure that aid is provided to truly deserving communities. The problem is that aid programs often do not work as intended, and are not effective in addressing economic inequality. One way to resolve this issue is to review the recipient's previous data. This research uses data mining to extract data from people who deserve assistance or not by applying clustering methods. Clustering, which is the process of grouping data without a class target (unsupervised learning), was used in this study. The algorithm used in this research is K-Means clustering. The results showed that there were two clusters of K-Means algorithm application, with 6 people in cluster 1 and 4 people in cluster 2. This research was successful and had an impact on aid providers to conduct more thorough data collection not just choosing the community to be given assistance.

Abstract

One of the most recent types of elections is the 2024 election, which includes the election of the president as well as legislative members. Along with the development of technology, an application called Sirekap emerged which is used to recapitulate the results of the vote. Although the app only has a one-star rating on the Play Store, reading all the user reviews to know the quality takes quite a while. Therefore, sentiment analysis can be an alternative to get an overview of user reviews so that it can help in making better decisions then, the method that will be used in conducting sentiment analysis in this study is the naïve Bayes algorithm. This research aims to identify and categorize user sentiment, as well as evaluate the quality of the app based on reviews provided on the Playstore. This research contributes by providing an efficient method to analyze user reviews of the Sirekap app, which can assist app developers and other stakeholders in making better decisions regarding app development and improvement. In addition, the results of this study confirm that the app's one-star rating is accurate, with evaluation metrics such as precision, memory, and f1 score reaching 1.00 each.

Abstract

Global economic instability, influenced by geopolitical turmoil, high inflation, and financial market pressures. This uncertainty can affect global stock price fluctuations, including MSFT shares. This study aims to analyze and predict MSFT's share price during periods of global economic instability using the ARRIMA time series approach. The data used for the analysis was 753 daily historical data on the closing price of MSFT shares. Based on the results of the stationary test using ADF, the data is non-stationary at the level, and becomes stationary after differentiating once. The best model for data was obtained from the ARIMA model (0,1,0) and obtained an AIC value of 4633,602, an RMSE of 11.20, showing quite good prediction results. The prediction results show that the MSFT share price prediction is close to USD 419 to USD 420. The results of this prediction can be used as a reference in understanding the movement of MSFT shares for investors during periods of global uncertainty.

Abstract

Indonesia is a country with an area of 1.9 million km², rich in diversity, including various languages in each region. This linguistic diversity gives each region its unique characteristics. However, in the 21st century, there is a noticeable decline in the use of regional languages, particularly in polite speech. This decline is attributed to the influence of Western culture, which has permeated Indonesia through technological advancements and television broadcasts showcasing urban and foreign cultures. The Javanese language, known for its unique *unggah-ungguh* (levels of politeness) and distinctive script, is one of the cultures at risk. The rapid development of technology, especially in education, necessitates its optimal utilization while preserving ancestral heritage such as the Javanese language. This study focuses on designing an optimal User Interface (UI) and User Experience (UX) for a Javanese language learning application on Android devices. The application includes features such as wulangan (lessons), pitakonan (questions), and tembang (traditional songs), with a focus on the User-Centered Design (UCD) approach. The research object is MI Nurul Islam, an elementary school in Brebes Regency. After the UI/UX design was successfully created, the System Usability Scale (SUS) was used to evaluate its effectiveness. The design received an average SUS score of 77.5, indicating that it is well-suited for further application development. The findings suggest that the designed application can significantly aid in preserving and promoting the use of the Javanese language among early childhood learners, addressing the decline caused by external cultural influences.

Abstract

At Universitas Amikom Purwokerto, the Institute for Research and Community Service (LPPM) faces significant challenges in financial data processing. Currently, financial data is managed using Microsoft Excel, and there is no system in place to properly manage and store this data. This lack of an efficient system hinders effective financial management and data handling. To address these issues, the proposed solution is to develop a website for financial management that supports the tri dharma of higher education. Effective web application development necessitates adherence to standard front-end framework models. Therefore, this study focuses on creating a front-end for the LPPM financial website using Bootstrap, following the waterfall method due to its sequential, structured, and reliable properties. The result of this study is a website-based LPPM financial application front-end. Based on test results, the front-end of this website achieved an SUS (System Usability Scale) score of 80.5, which falls into grade B. This indicates that the application is expected to facilitate the process of managing financial data and enhance user interaction with the system, effectively resolving the identified issues. This research was successful because it had created a front-end system in accordance with the needs that had been complained about by the university.

Abstract

This study aims to analyze the influence of study time and lecturer competence on the learning outcomes of Informatics students at Universitas Amikom Purwokerto. The method used in this research is quantitative with a survey approach and statistical analysis. The sample consisted of 64 students who had completed the Calculus course in the 2022/2023 academic year. Data were collected from the students' final grades and analyzed using multiple linear regression tests. The analysis results indicated no significant influence between study time (morning and afternoon) and lecturer competence on student learning outcomes, both simultaneously and individually. The F-test and t-test results demonstrated that both independent variables were insignificant in influencing student learning outcomes. Therefore, it can be concluded that study time and lecturer competence statistically do not significantly contribute to students' academic achievement in the Calculus course. This research suggests that other factors, such as teaching methods and student motivation, may play a more crucial role in determining academic success.

Abstract

This study aims to measure the success of the e-learning system implemented at SMA Negeri 1 Kroya by adopting the DeLone and McLean Information Systems Success Model. A descriptive quantitative approach was employed, with data collected through observations, interviews, and questionnaires distributed to 300 students selected randomly from a population of 1,004 students. The data were analyzed using Structural Equation Modeling (SEM) with the SmartPLS software. The evaluation focused on six constructs: system quality, information quality, service quality, system use, user satisfaction, and net benefits. The results indicate that the model has adequate explanatory power in explaining system use, user satisfaction, and net benefits. Hypothesis testing shows that information quality and service quality significantly affect system use, while system quality and information quality significantly influence user satisfaction. In addition, system use and user satisfaction have a significant impact on net benefits. However, system quality does not significantly affect system use, and service quality does not significantly influence user satisfaction. Indirect effect analysis reveals that user satisfaction plays a more dominant mediating role than system use. These findings highlight that user satisfaction and quality of experience are key factors in determining the success of e-learning implementation.
