Abstract

Indonesia has many variations of traditional food and interesting tourist destinations. The large number of tourist destinations make people like traveling and try to enjoy their traditional food. However, when trying traditional foods, especially foods that are new to them, they must be more careful, because the various ingredients contained in them have an impact on health. This research will try to make an application that can recognize Indonesian traditional food. The hope is that it can provide complete information, so that it can be used to develop calorie counter applications in the future. This study aims to design a system that can classify Indonesian traditional food images to help recognize food names with a certain level of accuracy using the EfficientNetV2 architecture. EfficientNetV2 is a new family of deep learning that excels in training as well as parameter efficiency. Deep Learning is a method often used to classify complex images. The EfficientNetV2 used in this study consists of four different architectures namely EfficientNetV2_S_21k, EfficientNetV2_M_21k, EfficientNetV2_L_21k, and EfficientNetV2_XL_21k. The dataset used comes from three types of data source categories, namely from Google Images, direct image capture using a Smartphone camera, and a combination of both. Each dataset category consists of 18 classes with a total of 1,800 images from Google Images, 1,800 images from Smartphone cameras, and 3,600 images from a combination of Google Images and Smartphone cameras. The dataset is taken from three categories to compare the level of accuracy and get the best accuracy value. The results of this study indicate that EfficientNetV2 can classify images of Indonesian traditional food with the highest test accuracy value of 99.4% from the EfficientNetV2-L(21k) model and the results obtained do not occur overfitting.

Abstract

Efforts to understand student performance have long been a highly-researched topic in the field of applied education computing. Current research in the field still places its focus on understanding and analyzing student performance using definitive variables such as the student’s scores and their cognitive capabilities, which by themselves already explain the student’s performance. The great diversity of Indonesian culture, which includes people from a wide range of socioeconomic origins, makes it all the more surprising that so little research has been done to examine the hidden socioeconomic aspects that may affect student performance. Research conducted on a single school may not be generalizable because of the diversity among them in terms of the elements that affect students' academic outcomes. In this investigation, we employ a causal modelling strategy that is data-driven to examine academic achievement. Data was retrieved from a public junior high school in Bali, Indonesia, and then processed with the Non-combinatorial Optimization via Trace Exponential and Augmented lagRangian for Structure Learning (NOTEARS) and Bayesian Network algorithm in order to discover a latent causal structure and the effect between variables discovered from the structure. Findings show that the average skill score of a student is significantly influenced by the distance from school, the education level and income of parents, and their place in the family. Meanwhile, the average knowledge score is mainly influenced by the average skill score, the order in the family, and the parent’s income level. The results of the study also show potential for practical implications where schools, researchers, and governments, can rethink their approach to education by analyzing data with the proposed approach. The limitations of this study include the quality of data to discover patterns and the limited number of variables used to study student performance factors. Future research may consider the use of more holistic, complete variables in order to discover more insights regarding student performance.

Abstract

Fake news has become a serious threat in the digital information era. This research aims to develop a model for detecting fake news in Bahasa Indonesia using a deep learning approach, combining the Long Short-Term Memory (LSTM) method with word representations from Word2vec Continuous Bag of Words (CBOW) to achieve optimal results. Our main model is LSTM, optimized through hyperparameter tuning. This model can process information sequentially from both directions, allowing for a better understanding of the news context. The integration of Word2vec CBOW enriches the model's understanding of word relationships in news text, enabling the identification of important patterns for news classification. The evaluation results show that our model performs very well in detecting fake news. After the tuning process, we achieved an F1-Score of 97.30% and an Accuracy of 98.38%. 10-fold cross-validation yielded even better results, with an F1-Score and Accuracy reaching 99%.

Abstract

Hotel reviews not only provide useful information for business owners but also shape the image of the hotel in the eyes of customers. Reviews generally cover various aspects expressed honestly by customers. In the era of technological development, the number of hotel reviews online is increasing, making the processing of hotel assessments discussed in reviews a challenge for many parties. To overcome this, a multi-aspect sentiment analysis has been developed to help extract more specific information about hotel evaluations from each review sentence. The aspects evaluated in the reviews include price, location, service, food, facilities, and rooms. In developing the multi-aspect sentiment analysis model, a deep learning method based on LSTM is used. The LSTM model architecture is built using a sequential model with four layers: embedding, SpatialDropout1D, LSTM, and dense. The model is trained with 10 epochs and a batch size of 32. The model is evaluated through three scenarios, including testing sentences with one aspect, testing sentences with a combination of two aspects, and testing sentences with a combination of three aspects. Top-1 and Top-2 accuracy are applied to test sentences with a combination of two and three aspects. Meanwhile, F1_score is used for testing sentences with one aspect and sentiment analysis. The obtained accuracy results are 79% for Top-2 accuracy in sentences with a combination of two and three aspects, 85.7% for F1_score in sentences with one aspect, and 83% for F1_score accuracy in sentiment analysis. These results indicate that the developed model is capable of performing multi-aspect sentiment analysis on hotel reviews.

Abstract

Fish is one of the ingredients for consumption that provides high-quality protein and can help form a healthy lifestyle. The perishable quality of fish meat demands that consumers be smart in sorting out the fish to be consumed. Therefore, knowledge about the freshness condition of fish meat is important for consumers. This study tries to build a mobile-based application that applies the Deep Learning model, using architecture You Look Only Once (YOLOv4) and YOLOv4-Tiny to detect the freshness level of fish based on the eyes and skin of the fish. The level of freshness used is fresh, medium, and spoil. The dataset used by the model are images of Deho tuna fish (Euthynnus Affinis), Manglah fish (Priacanthus Tayenus), Solok fish (Rastrelliger Brachysoma), Mackerel fish (Scomber Australasicus), Kuwe Lilin fish (Caranx Melanophygus), Teribang fish (Nemipterus virgatus), Banyar fish (Restrelliger Kanagurta), and Kolong fish (Atule mate). The mAP achieved by YOLOv4 is 99.17% and YOLOv4-Tiny is 97.25%. The fastest processing time, the freshness level of fish meat in the application reaches 2.5 seconds per image for YOLOv4 and 0.15 seconds for YOLOv4-Tiny.

Abstract

Shopee has evolved into one of the leading e-commerce platforms connecting sellers with consumers. However, the challenge of keeping users active and engaged on the platform has become increasingly complex. User retention, the ability of a platform to sustain and enhance user presence, is a key factor in the long-term success of an e-commerce platform. Understanding the factors influencing users' decisions to remain active or cease interactions with the platform involves analyzing various variables, including user behavior, preferences, shopping experiences, and interactions with the platform. This research is designed to develop an effective user retention prediction model using data from new Shopee users. By analyzing the data and applying machine learning techniques using Logistic Regression, Decision Tree, Gaussian Naive Bayes, Random Forest, KNN (K-Nearest Neighbors), MLP (Multi-Layer Perceptron), AdaBoost, and XGBoost methods, this study predicts user retention within a 14-day period after registration on Shopee. The results of this research indicate that the Random Forest model performs the best with an Accuracy value of 0.733677, Precision of 0.702161, Recall of 0.811626, and F1-Score of 0.752936. Cross-validation values demonstrate the model's consistency with an Accuracy of 0.727626, Precision of 0.698143, Recall of 0.801884, and F1-Score of 0.746328. The Random Forest model becomes a model with a high recall value, indicating good sensitivity in identifying users who retain. Consequently, the results of this research provide valuable insights for Shopee in developing retention strategies for new users, which is an important aspect in the growth and sustainability of the e-commerce business.

Abstract

Social media has transformed into a global platform for expression and interaction where users can share photos, images, and videos. The rapid development and widespread use of social media afford the opportunity to analyze the construction of social life in societies and communities. As a result of alterations in lifestyle during the COVID-19 pandemic, mental health disorders increased. Mental health is a complex disease involving numerous individual, socioeconomic, and clinical variables. Natural language processing and analysis methods are required to address this complexity. The classification of mental health-related texts, which can serve as early warnings and early diagnoses, is facilitated by analytical and natural language processing techniques. In this investigation, a CNN-BiLSTM model was utilized, which was aided by a FastText-based word weighting method. The utilized data set consists of texts on mental health with labels such as borderline personality disorder (BPD), anxiety, depression, bipolar, mentalillness, schizophrenia, and poison. There are 35000 training records and 6108 test records. The data will undergo a data cleansing procedure, which will include lower text stages, number removal, reading mark removal, and stopword removal. Modeling with CNN-BiLSTM and FastText weighting yielded an F1-Score and accuracy of 85% and 85%, respectively. In comparison to the Bi-LSTM model, the F1-Score and accuracy were both 83%.

Abstract

The curriculum has changed once again with the introduction of the Merdeka Curriculum to address learning loss in the education sector. Its implementation has elicited various responses, such as support for granting teachers the freedom to innovate, focusing on essential materials, offering diverse learning methods, and fostering student creativity. However, criticism has also arisen, including issues related to teachers’ lack of understanding, parents' concerns, and the increased workload on students due to numerous projects. To improve educational policies, an in-depth analysis of these responses is essential. This study aims to analyze public sentiment toward the Merdeka Curriculum by applying Aspect-Based Sentiment Analysis (ABSA) using data from Twitter. The research focuses on four main aspects: Teaching Modules (MA), Education Reports (RP), the Merdeka Teaching Platform (PMM), and the Strengthening of the Pancasila Student Profile Projects (P5). Data were collected using specific and relevant keywords for each aspect, followed by preprocessing, labeling, and filtering based on sentiment and aspect. The final dataset comprised 2,359 valid tweets. The ABSA model was developed using IndoBERT with fine-tuning, then tested and evaluated. The results showed that the aspect classification model achieved an accuracy of 97%, F1 score of 97%, recall of 97%, and precision of 97%. Meanwhile, the sentiment classification model achieved an accuracy of 85%, F1 score of 85%, recall of 85%, and precision of 85%. This ABSA model is expected to assist in monitoring public responses and provide valuable insights for policy development, particularly within the context of the Merdeka Curriculum.
