Abstract

This study investigates the application of the Non-dominated Sorting Genetic Algorithm II (NSGA-II) for optimizing multiple conflicting objectives related to student academic performance. Using the Student Performance dataset from the UCI Machine Learning Repository, which contains demographic, behavioral, and academic information of 395 secondary school students, the research aimed to maximize final grades (G3), minimize absenteeism, and maximize study time. The study began with exploratory data analysis, which revealed wide variability in academic outcomes, low average absenteeism, and moderate study time, justifying the selection of these three objectives. NSGA-II was then implemented with a population of 100 individuals across 200 generations, employing crossover and mutation operators to generate Pareto-optimal solutions. The results demonstrated diverse non-dominated solutions, illustrating trade-offs between academic achievement, attendance, and study time. Absenteeism emerged as the most significant negative factor, while study time and school support were positively associated with better outcomes. Unlike conventional regression or classification methods that produce a single prediction, NSGA-II provided a spectrum of optimal alternatives, offering flexibility in policy and decision-making. These findings highlight the relevance of multi-objective optimization in education and emphasize the importance of integrating behavioral, social, and digital dimensions to design adaptive strategies for improving student performance.

Abstract

Sentiment analysis is a widely used method to understand customer opinions about a product. This study aims to analyze the sentiment of food and beverage product reviews on the Tokopedia marketplace using the Long Short-Term Memory (LSTM) approach and word embedding. The data used consisted of customer reviews that were categorized into three sentiment classes, namely positive, neutral, and negative. The model was developed through a series of stages of preprocessing, embedding, training with LSTM, as well as performance evaluation using accuracy and F1-score metrics. The results show that the developed model is able to classify sentiment with a fairly high level of accuracy. Based on the results of the final test on 5,000 data, the model managed to classify 122 data as negative, 130 data as neutral, and 4,871 data as positive, although it still showed an imbalance in class classification. Further analysis through word cloud visualization showed that words like "delicious", "steady", and "good" dominated the positive sentiment, while words like "disappointed", "broken", and "slow" often appeared in negative sentiment. This study provides valuable insights for businesses in understanding customer opinions and improving the quality of products and services.

Abstract

Parkir merupakan keadaan suatu kendaraan yang tidak bergerak yang bersifat sementara dengan pengemudi meninggalkan kendaraannya. Sistem parkir yang tertata dengan baik akan membuat pengguna kendaraan merasa nyaman serta pengelolaan parkir menjadi lebih efektif dan efisien. Salah satu pemanfaatan teknologi yang dapat memecahkan permasalahan tersebut adalah dengan membuat sistem manajemen parkir menggunakan pengolahan citra digital dengan melakukan pengenalan pola yang memanfaatkan metode image processing Optical Character Recognition (OCR) pada gambar plat nomor kendaraan yang telah diambil ketika kendaraan masuk ke area parkir. Berdasarkan percobaan yang telah dilakukan, simulasi ini menunjukkan bahwa sistem dalam peneliti ini dpat bekerja dengan baik antara sensor alat yang digunakan, printer thermal yang dapat mencetak lokasi kosong tempat parkir serta website yang dapat menampilkan riwayat data kendaraan yang telah menggunakan tempat parkir.Keyword: parkir, arduino, image processing, Optical Character Recognition
