Abstract

This study investigates user sentiment towards the myIM3 application, an application used for telecommunication service management in Indonesia. Using text analysis and machine learning methods, we analyzed user reviews to identify dominant sentiment patterns and evaluate different classification models. Word cloud analysis, sentiment distribution, and donut plots were utilized to gain deeper insights into user preferences and issues. Results indicate that the majority of user reviews are neutral (52.2%), with 37% positive reviews and 33.4% negative reviews. Users consistently pay attention to aspects such as internet connection (Neutral: 92%, Positive: 95%, Negative: 87%) and pricing (Neutral: 92%, Positive: 92%, Negative: 93%) in their reviews. Evaluation of classification models like Decision Tree Classifier, Support Vector Machine (SVM), and Random Forest shows that the SVM model performs the best with an accuracy of 93%, high precision (Negative: 93%, Neutral: 92%, Positive: 95%), recall (Negative: 93%, Neutral: 95%, Positive: 91%), and F1-score (Negative: 93%, Neutral: 94%, Positive: 93%). These findings can serve as a basis for service improvement and better product development in the future, while also affirming the capability of text analysis and machine learning techniques in providing valuable insights for telecommunication service providers.

Abstract

This research compares unsupervised learning methods in topic extraction and modeling in large-scale text corpora. The methods used are Singular Value Decomposition (SVD) and Latent Dirichlet Allocation (LDA). SVD is used to extract important features through term-document matrix decomposition, while LDA identifies hidden topics based on the probability distribution of words. The research involves data collection, data exploratory analysis (EDA), topic extraction using SVD, data preprocessing, and topic extraction using LDA. The data used were large-scale text corpora. Data explorative analysis was conducted to understand the characteristics and structure of text corpora before topic extraction was performed. SVD and LDA were used to identify the main topics in the text corpora. The results showed that SVD and LDA were successful in topic extraction and modeling of large-scale text corpora. SVD reveals cohesive patterns and thematically related topics. LDA identifies hidden topics based on the probability distribution of words. These findings have important implications in text processing and analysis. The resulting topic representations can be used for information mining, document categorization, and more in-depth text analysis. The use of SVD and LDA in topic extraction and modeling of large-scale text corpora provides valuable insights in text analysis. However, this research has limitations. The success of the methods depends on the quality and representativeness of the text corpora. Topic interpretation still requires further understanding and analysis. Future research can develop methods and techniques to improve the accuracy and efficiency of topic extraction and text corpora modeling.

Abstract

Tujuan penelitian ini yaitu untuk mengetahui penyimpangan keuangan yang terjadi di lingkungan Rumah Sakit. Penyimpangan transaksi keuangan ini melibatkan aktivitas dokter, pembuatan resep dan apotik atau farmasi serta bagian keuangan Rumah Sakit. Setiap dokter yang mengeluarkan resep untuk pengobatan pasien, diharapkan pasien membeli obat di apotik Rumah Sakit itu sendiri sehingga transaksi keuangannya menjadi pemasukan bagi Rumah Sakit. Namun sebaliknya, hal ini bisa mempersulit mengetahui pemasukan kas yang diperoleh dari setiap dokter terkait resep yang dikeluarkan. Oleh karenanya penelitian ini dilakukan dengan membuat model untuk mengetahui penyimpangannya. Untuk mendapatkan model yang terbaik dilakukan evaluasi model terhadap algoritma Gradient Boosted Tree(GBT) dan Random Forest(RF). Hasilnya adalah AUC (Area Under the Curve) model GBT = 0.976 dan AUC model RF = 0.964 yang menunjukkan bahwa algoritma GBT pilihan terbaik untuk pemrosesan penyimpangan transaksi keuangan dataset medis di Rumah Sakit ABC.

Abstract

Abstract This research aims to determine the Support Vector Machine (SVM) model with Parameter Optimization in predicting loan worthiness to avoid the risk of bad credit at the Bank. Every bank tries to market financial loan products with very strict requirements. One of the requirements is that the company's financial reports must be healthy if it borrows money from a bank to develop the company's business. In the credit analysis process, there are 19 financial factors that must be measured from dozens or even hundreds of companies proposing financial loans, making it difficult for credit analysts to make decisions about whether these companies are worthy of borrowing or not. Therefore, this research was carried out by comparing the two models, namely SVM with parameter optimization and SVM with parameter optimization and Particle Swarm Optimization (PSO) to select the best model. The research results show that the Area Under Curve (AUC) criteria with validation number of folds (nof) = 10 and nof = 5 are 98.80% and 98.80%, meaning good and stable in the SVM model with parameter optimization. Meanwhile, the SVM model with parameter optimization and PSO has better AUC for validation nof=5 (99%) but for AUC with validation nof=10 (98.30%) it is less good.

Abstract

Teknologi informasi yang berkembang pesat terus melahirkan inovasi yang mempermudah manusia dalam melakukan komunikasi dan mendapatkan informasi. Dengan berkembangnya suatu teknologi kita dapat berinteraksi dengan satu sama lain tanpa ada batasan tempat dan waktu. Hal ini dapat terjadi karena adanya suatu wadah (forum) komunitas yang bisa dijadikan media untuk berdiskusi secara online. Pada Perguruan Tinggi Raharja, setiap mahasiswa diberikan fasilitas berupa email resmi yaitu Rinfo yang digunakan sebagai media komunikasi. Namun saat ini belum tersedia wadah untuk berdiskusi antara mahasiswa dan dosen, sehingga proses diskusi pembelajaran belum efektif dan efisien karena masih dilakukan secara tatap muka. Oleh karena itu, diperlukannya pemanfaatan RinfoApps yang dapat digunakan sebagai wadah diskusi pembelajaran online. Hangouts merupakan salah satu GoogleApps yang dapat dimanfaatkan sebagai wadah formal untuk proses diskusi pembelajaran online. Dengan membuat Grup Google Hangouts di setiap kelas, mahasiswa dan dosen dapat berdiskusi di luar jam perkuliahan, dosen dapat sharing mengenai bahan materi pembelajaran. Dalam penelitian ini, ditemukan 3 (tiga) permasalahan pada keadaan saat ini. Lalu dengan didukung 2 (dua) metode penelitian yaitu metode observasi dan studi pustaka. Hasil akhir yang dicapai dari penelitian ini yaitu terbentuknya media diskusi yang dapat di akses dimana dan kapan saja sehingga proses diskusi antara mahasiswa dan dosen menjadi lebih efektif dan efisien.

Abstract

This research aims to determine the process of creating a quick response code (QR code) model with Reed Solomon error correction for employee attendance at the Company. Fingerprint attendance systems, even though they are more sophisticated, still have disadvantages, such as difficulties in use in unhygienic environments, as well as high costs for installing the device. Apart from that, traditional attendance is also less flexible in managing employees who work in the field or employees who do not work in the main office. Companies that have many branches or employees who work outside the main office often have difficulty monitoring absenteeism effectively and accurately. The mechanism of this QR code model is carried out through several steps, namely: coding QR codes based on employee ID numbers, grouping encoder data every 8 bits, converting encoder data to binary format, error correction using the Reed Solomon algorithm, creating error correction codes (EC). ) in polynomial form, calculating error correction data based on the correspondence and index of integer numbers in the Galois Field (GF), calculating the function f′(x) through an iterative division process until completion, determining the remainder of the division in the form of R(x), as well as merging encoder data with error correction code as result end. With this mechanism, the QR code-based attendance system is able to maintain data security and accuracy while minimizing the occurrence of anomalies during the work attendance process.

Abstract

This study aims to evaluate and compare the performance of two time series forecasting approaches: the classical statistical ARIMA model and the deep learning-based LSTM model, in the context of forecasting product inventory demand in a production company. The data used consists of historical daily demand records, totaling 100 and 200 records, which were analyzed to identify linear and non linear patterns. The ARIMA model was selected for its reliability in modeling stationary and seasonal data, while the LSTM model was utilized to capture complex temporal patterns through its layered neural network architecture. The test results using the MSE and RMSE metrics show that in both datasets, the ARIMA model has better prediction performance (100 records, RMSE=45.61% and 200 records, RMSE=44.72%) compared to LSTM, namely 100 records, RMSE=45.93% and 200 records, RMSE=49.54%. Although LSTM excels in handling non-linear dynamics, ARIMA outperformed it on data with linear. This study highlights the importance of selecting forecasting models based on data characteristics and suggests opportunities for future exploration of hybrid models. The theoretical and empirical foundations of this research are supported by the works of Hyndman & Athanasopoulos (2018), Hochreiter & Schmidhuber (1997), and Makridakis et al. (2018), which provide critical insight into predictive modeling for time series analysis.

Abstract

SMK Bina Amma'mur has a section in charge of taking care of computers ranging from computer hardware repair and computer software repair, namely the IT helpdesk section. Currently, the process of informing computer repairs that are currently running is still carried out by means of teachers or staff asking for help from the Information Technology department by meeting directly to check problems that occur on computers or laptops, then the IT helpdesk will send a team of technicians to solve the reported problems, if it has been completed, it will be reported back to the IT helpdesk to note that computer repair requests have been made. After checking the problem that occurs on the computer or laptop then the IT department will record the problem in the general ledger and will notify the teacher or staff when it has been resolved via whatsapp media. However, the handling of problems that are running is still not good because the process of recording repair results is still manual so that it affects the performance of the IT department. This can have a negative impact, namely there are problems recording data repeatedly, the process of searching for computer repair data takes a long time because you have to search one by one for repair request data in books, there are often errors in making reports so that the reports made are not the same as the computer repair process. This research resulted in an IT helpdesk system that aims to help the IT department manage IT helpdesk data better. This research uses the PIECES analysis method, design using UML and blackbox testing system. The IT Helpdesk system is created using PHP programming language and MySQL database.
