Abstract

This paper aims to evaluate the accuracy of the k-Nearest Neighbors regression method in predicting the Jakarta Composite Index (JCI), thus adding evidence of the application of k-NN regression in predicting noisy financial time series data. The dataset consists of daily data from several time series variables in 2022. The result suggests that the accuracy of k-NN regression in predicting JCI fluctuation is very good, indicated by Mean Absolute Percentage Error (MAPE) being less than 2% for k = 2, 3, …, 10.

Abstract

The purpose of this study is to examine the effect of profitability and leverage, either partially or jointly, on firm value in the construction of companies listed on the Indonesia Stock Exchange in 2017-2021. The data analysis method in this study uses multiple linear regression to predict the effect of the independent variables. The population in this study was the construction of the Indonesia Stock Exchange company building in 2017-2021, then 11 samples were obtained with 5 years of observation and 55 observations were obtained according to the criteria. The results showed that profitability and leverage, both simultaneously and partially, affected the value of the company's building construction companies listed on the Indonesia Stock Exchange for that period. Profitability affects the value of the company, this shows that high profits will lead to an increase in business value. Leverage does not affect firm value, this shows that a high level of leverage does not affect the number of short-term and long-term debts that must be paid off by the company.

Abstract

One way to maintain consistent quality and reduce losses caused by defective products is through preventive costs, assessment costs, and internal failure costs. This research aims to: (1) Determine the combined impact of preventive costs, assessment costs, and internal failure costs. (2) Identify which of these costs—preventive, assessment, or internal failure has a greater influence on defective products. The research method employed is quantitative descriptive. Sample selection follows the Purposive Sampling method, using quality cost reports from the ASQIRO packaged drinking water company for the years 2020–2023. Hypothesis testing is conducted using (1) F-test, (2) coefficient of determination test, (3) t-test, and SE/SR calculations. Based on the research results, there is a significant influence of preventive costs, assessment costs, and internal failure costs both simultaneously (as indicated by an F-test significance value of 0.000 < 0.05) and individually (parsially) with t-test results showing significance values for preventive costs (0.000 < 0.05), assessment costs (0.030 < 0.05), and internal failure costs (0.032 < 0.05). The study also reveals that preventive costs (SE: 49.00%) have a greater impact on defective products compared to assessment costs (SE: 21.04%) and internal failure costs (SE: 3.09%).

Abstract

This study aims to examine the phenomenon of integration-interconnection in the context of the increasing popularity of Islamic boarding schools and the marginalization of public schools in Indonesia. Islamic boarding schools, which are increasingly in demand as religious-based education, are faced with public schools that face the challenge of relevance amidst global competition. The main problem of this study is the tension between the two educational systems and the potential of the concept of integration-interconnection to create harmonious synergy. Library research method with a descriptive-analytical approach. Data were collected from various literatures, such as books, scientific journals, and policy documents, then analyzed using content analysis techniques. This study identifies challenges, opportunities, and solutions in implementing integration-interconnection. The results of the study indicate that integration-interconnection can be a strategic solution to address educational challenges in Indonesia. The main findings include the need for curriculum renewal, improving the competence of teaching staff, and changing the paradigm of society to accommodate the synergy between Islamic values ​​and modern science. In conclusion, integration-interconnection is not just a theoretical concept, but a strategic need to create inclusive education that is relevant to global challenges and oriented towards the harmony of religious values ​​and modernity.

Abstract

Pemikiran Pendidikan Masa Bani Umayyah (661-750 M) menggambarkan periode transisi yang penting dalam sejarah pendidikan Islam. Studi ini menggunakan metode kajian literatur untuk mengeksplorasi karakteristik pendidikan, tempat-tempat pendidikan, dan perkembangan pemikiran pendidikan pada masa tersebut. Dinasti Umayyah, meskipun awalnya dianggap negatif oleh sejarawan, memiliki dampak signifikan dalam perkembangan pendidikan Islam. Pendidikan pada masa ini mencerminkan identitas Arab dan Islam yang kuat, dengan fokus pada pembelajaran Al-Quran, sastra Arab, ilmu-ilmu agama, dan bahasa Arab. Tempat-tempat pendidikan seperti khuttab, masjid, majelis sastra, pendidikan istana, badiah, perpustakaan, rumah sakit, serta pemikiran pendidikan yang tercermin dalam nasihat-nasihat khalifah dan tulisan ulama, semuanya membentuk landasan penting bagi perkembangan pendidikan Islam. Meskipun ada kendala politik dan sosial, masa Bani Umayyah memberikan dorongan signifikan bagi pengembangan ilmu pengetahuan dan pemikiran pendidikan Islam yang menjadi dasar bagi masamasa yang akan datang.

Abstract

In the digital era, online news has become one of the primary sources of information, encompassing various categories such as politics, technology, entertainment, and business. The increasing volume of news poses challenges in organizing and categorizing information into relevant categories. This study aims to enhance the accuracy of news text classification through a data augmentation approach based on synonym replacement. The methods employed include text preprocessing for data cleaning, augmentation using synonym replacement to improve data diversity, feature representation using TF-IDF and Word2Vec, and modeling with Neural Networks. Evaluation metrics such as accuracy, precision, recall, and F1-score were used to assess performance. The results indicate that data augmentation can improve model accuracy by up to 95%, with balanced training and validation data distributions. The confusion matrix shows that most data can be correctly classified, although some errors occur in categories with similar features. This study demonstrates that synonym replacement-based data augmentation is effective in improving news text classification performance, particularly for datasets with limited training data.

Abstract

The financial management training at TK Bustanul Athfal Lhong Raya aims to enhance the capacity of the school administrators in managing finances transparently and accountably. The issues faced by the administrators include a lack of skills in structuring financial documents and limited use of technology. This training involved the school principal, treasurer, teachers, and representatives from the school committee as participants, covering topics such as budgeting, cash flow recording, and the preparation of simple financial reports. The methods combined theory and practice to ensure participants could implement what they learned in their daily activities. The results showed a significant improvement in participants' understanding and skills in managing financial documents in a more structured and transparent manner, as evidenced by their ability to create daily cash books, annual budgets, and more systematic financial reports. Post-training monitoring confirmed that most participants had applied the taught materials in managing school finances, although further assistance is required, especially in the use of financial technology. This activity successfully established a better financial management system, increased transparency, and built trust among the community in the financial management of TK Bustanul Athfal. This training provides a strong foundation for accountable and sustainable financial management in TK Bustanul Athfal Lhong Raya Banda Aceh.
