Abstract

Public complaint services are an important component in efforts to improve the quality of public services within the local government environment. However, in many sub-districts, the complaint mechanism is still carried out manually or conventionally, resulting in various problems, such as delays in handling complaints, poorly organized report documentation, and low levels of information transparency to the public. This study aims to analyze system needs and design a model for public complaint information services based on information technology that can be implemented at the sub-district level. The research method used is system needs analysis through observation and interviews with sub-district officials, as well as literature studies related to the application of information systems in public services. The results of the study produced a model for a public complaint information system that is able to facilitate structured complaint recording, accelerate the follow-up process, and provide a feature for monitoring the status of complaints in real-time by the public. The implementation of the system model can improve the effectiveness, efficiency, and accountability of complaint services in sub-districts, as well as encourage the realization of more transparent and responsive public services.Keywords: Information Systems; Public Complaints; Public Services; Sub-districts; Information TechnologyAbstrakPelayanan pengaduan masyarakat merupakan salah satu komponen penting dalam upaya peningkatan kualitas pelayanan publik di lingkungan pemerintahan daerah.

Abstract

Diabetes was a chronic disease that continued to increase globally, making early detection essential to reduce long-term complications. This study aimed to develop a desktop-based diabetes prediction system that provided fast and simple classification results for medical personnel and individual users. The system used the entropy-based subset selection (E-ss) method to choose the most relevant attributes and a classification tree to classify the risk. The dataset from the National Institute of Diabetes and Digestive and Kidney Diseases, contained 768 patient records with attributes such as number of pregnancies, glucose level, blood pressure, and other risk factors. The E-ss process produced three attributes with the highest information scores, namely body mass index (BMI), blood pressure, and triceps skinfold thickness. These three attributes were then used as input to the classification tree model to generate diabetes risk predictions. Cross-validation testing showed an accuracy of up to 78.95%. These findings indicated that E-ss feature reduction helped maintain prediction performance while improving computational efficiency. This system was expected to serve as a practical and reliable diagnostic tool.

Abstract

Network attacks pose a serious threat to the security of digital infrastructure, making accurate and efficient detection an urgent necessity. The National Cyber and Crypto Agency (BSSN) recorded 330,527,636 instances of anomalous traffic or network attacks. This sheer volume renders  manual  handling  by  cybersecurity  personnel  highly  impractical.  Consequently, a detection system based on Machine Learning (ML) is required. However, single machin e learning models have proven suboptimal in effectively resolving this complex problem. This research aims to develop a robust Network Intrusion Detection Model by employing advanced Ensemble Learning techniques—specifically Bagging, Boosting, and Stacking—to significantly optimize the performance of the base ML models. The study utilizes the UNR-IDD dataset. The methodology begins with comprehensive Data Preprocessing, including Min-Max Scaling and Dimensionality Reduction. Model performance is comprehensively evaluated using classification metrics across three distinct data splitting scenarios (70:30, 80:20, and 90:10) to identif y the optimal configuration. The experimental results demonstrate that the Stacking Ensemble Learning approach achieves the most optimal accuracy among the tested methods.Keywords: Network Intrusion Detection; Machine Learning; Ensemble Learning; Stacking; Dimensionality ReductionAbstrakSerangan jaringan telah menjadi ancaman serius bagi keamanan inf rastruktur digital .

Abstract

Technological advancements in the Fourth Industrial Revolution have transformed higher education, yet accreditation processes often suffer from inefficient data management, causing delays, inconsistencies, and limited monitoring of performance indicators. This study designs a data warehouse integrated with a dashboard and Early Warning System (EWS) to improve accreditation data management at University X, West Jakarta. Using Kimball’s Dimensional Model, data were structured into fact and dimension tables, with collection methods including interviews with the Head of the IT Department and document analysis of accreditation processes. Descriptive statistics were applied to identify trends and patterns. The dashboard enables real-time visualisation of key metrics, while the EWS issues alerts on missing or outdated data. Results show that the snowflake schema enhances data organisation and clarity, reducing manual processing and facilitating proactive monitoring. The system supports more efficient accreditation management and strengthens institutional readiness for assessment.

Abstract

This study discussed the challenges of stock price prediction, which is volatile and exhibits non-linear patterns, as well as the need for an easily accessible system to present prediction results quickly. A web-based application was developed to predict the closing prices of Indonesian non-banking stocks (ASII, TLKM, and UNVR) by utilizing daily market data that were updated periodically through an application programming interface. The integrated pre-trained models used were long short-term memory (LSTM) and convolutional neural network–long short-term memory (CNN-LSTM), which were integrated into the application for one-step-ahead (t+1) inference. The system development methodology followed the software development life cycle waterfall model. Functional testing using a black-box testing approach showed that the core features ran according to the requirements, so the application was considered suitable as a web-based medium for prediction and visualization.Keywords: Stock price prediction; Web application; Deep learning; Application programming interface; Non-banking stocksAbstrakPergerakan harga saham yang volatil dan non-linear menuntut pendekatan prediksi yang adaptif serta sistem yang mudah diakses.

Abstract

The rapid growth of digital music has driven the need for accurate and efficient automated music genre classification systems. This study evaluates a hybrid approach that integrates the ResNet-50 architecture as a feature extractor through transfer learning and LightGBM as a classifier. Using the GTZAN dataset represented as Mel-spectrograms, the research compares the effectiveness of hyperparameter optimization using Random Search and Grid Search methods. Based on performance evaluation, the hybrid scenario optimized with Grid Search yielded the best performance with an accuracy of 81.20%, outperforming the Random Search method. Nevertheless, the overall experimental results reveal that the end-to-end ResNet-50 model still provides superior performance compared to the hybrid approach. This indicates that the deep features from ResNet-50 are highly representative for separating genre classes, such that the addition of an external ensemble classifier does not yield significant improvements, although the hybrid approach still offers valuable empirical insights as a stable alternative model.Keywords: Convolutional Neural Network; ResNet-50; LightGBM; Mel-Spectogram; Klasifikasi Genre Musik;AbstrakPertumbuhan pesat musik digital mendorong kebutuhan akan sistem klasifikasi genre musik otomatis yang akurat dan efisien. Penelitian ini mengevaluasi pendekatan hibrida yang mengintegrasikan arsitektur ResNet-50 sebagai pengekstraksi fitur melalui teknik transfer learning dan LightGBM sebagai classifier. Menggunakan dataset GTZAN yang direpresentasikan dalam bentuk Mel-spectrogram, penelitian ini membandingkan efektivitas optimasi hyperparameter menggunakan metode Random Search dan Grid Search. Berdasarkan evaluasi kinerja, skenario hibrida dengan optimasi Grid Search terbukti menghasilkan kinerja terbaik dengan akurasi 81,20%, mengungguli metode Random Search. Kendati demikian, hasil eksperimen secara keseluruhan mengungkapkan bahwa model ResNet-50 end-to-end masih memberikan performa yang lebih unggul dibandingkan pendekatan hibrida. Hal ini mengindikasikan bahwa fitur mendalam dari ResNet-50 sudah sangat representatif untuk memisahkan kelas genre, sehingga penambahan classifier eksternal tidak memberikan peningkatan signifikan, meskipun pendekatan hibrida tetap menawarkan wawasan empiris penting sebagai model alternatif yang stabil.
