Abstract

Reviews are texts that contain an assessment or comment on something and can be used to provide more in-depth information. This research aims to analyze community reviews of the Mandalika Circuit using the aspect-based sentiment analysis technique CNN method. The CNN model is trained using two types of word embedding, namely Keras and FastText, and supported by the Multilabel Stratified K-Fold Cross Validation method to ensure an even distribution of data on each label and produce a stable accuracy evaluation. The results show that CNN with FastText word embedding has a higher average accuracy than CNN with Keras word embedding for both aspect and sentiment classification tasks. However, the model had difficulty in classifying the positive class in the sentiment label, which was due to the smaller amount of review data with positive sentiment than neutral and negative. Therefore, for future research, it is recommended to use data augmentation techniques on the imbalanced classes to improve the accuracy of the model.

Abstract

Although Indonesia has the third largest population in the world, the number of datasets available in the field of text processing in Indonesian is still very limited. Therefore, this research utilizes the ability of multilingual models that can be trained with multiple languages to predict emotions based on low-resource language such as Indonesian. Several training scenarios were conducted to evaluate the transferability and performance of these multilingual models compared to the monolingual IndoBERT model. The experimental results show that XLM-R outperforms mBERT and achieves competitive performance to IndoBERT, with XLM-R and IndoBERT achieving F1-score of 0.7793 and 0.7733 respectively. XLM-R also demonstrates competitive results on other evaluation metrics. These findings suggest that XLM-RoBERTa could be a promising alternative for emotion detection in languages with limited resources, such as Indonesian.

Abstract

Peningkatan kasus Covid-19 di Indonesia memberikan rasa khawatir bagi hampir seluruh masyarakat, Dilihat dari persebaran tiap provinsi untuk kasus positif, sembuh, dan meninggal tidak menunjukkan sebuah grafik yang linier. Seperti pada data harian kasus per provinsi di akhir bulan April 2021 dimana kasus positif dan sembuh terbanyak terdapat pada Provinsi DKI Jakarta, untuk kasus meninggal Provinsi Jawa Timur berada di posisi pertama, dan di posisi empat untuk kasus positif dan meninggal. Data persebaran yang abstrak ini membuat pengelompokan persebaran Covid-19 di Indonesia menjadi sukar untuk dilakukan. Penelitian ini mengelompokkan provinsi-provinsi berdasarkan persebaran Covid-19 di Indonesia dengan cara mengimplementasikan metode Fuzzy C-means serta metode Elbow. Fuzzy C-means adalah metode pengelompokan berbasis fuzzy yang dapat melakukan persebaran data pada seluruh cluster berdasarkan derajat keanggotaan yang dimilikinya. Sedangkan untuk menentukan jumlah cluster terbaik akan diimplementasikan metode Elbow. Metode Elbow membandingkan perbandingan hasil sum square error (SSE) dari setiap cluster dan mendapatkan jumlah cluster terbaik dari perubahan nilai SSE yang signifikan atau membentuk siku (elbow). Penggunaan Fuzzy c-means sebagai metode pengelompokan untuk mencari tahu seberapa besar pengaruh yang dimiliki setiap data terhadap masing-masing cluster. Karera metode-metode sebelumnya yang digunakan pada objek yang sama hanya melakukan pengelompokan saja secara tegas, tanpa memperhatikan besarnya pengaruh sebuah data terhadap seluruh cluster. Pengelompokan dilakukan menjadi tiga buah cluster atau kelompok berdasarkan parameter kasus positif, sembuh, dan meninggal Covid-19 per 27 April 2021. Cluster 1 hanya terdiri tiga provinsi yaitu Jawa Barat, Jawa Tengah, dan Jawa Timur. Cluster 2 DKI Jakarta, dan sisanya masuk ke cluster 3. AbstractThe increase in Covid-19 cases in Indonesia raises concerns for all parties, When viewed for the distribution of each province, positive, recovered and dead cases do not show a linear graph. As in the daily data of cases per province at the end of April 2021 where the most positive and recovered cases were in DKI Jakarta Province, while for dead cases, East Java Province was in first position, and in fourth position for positive and dead cases. This abstract distribution data makes it difficult to classify the distribution of Covid-19 in Indonesia. This study will group provinces based on the spread of Covid-19 in Indonesia using the Fuzzy C-means method and the Elbow method. Fuzzy C-means is a fuzzy-based grouping method that allows all data to be members of all clusters formed with their respective degrees of membership. Meanwhile, to determine the best number of clusters, the Elbow method will be implemented. The Elbow method compares the sum square error (SSE) results from each cluster and gets the best number of clusters from a significant change in the SSE value or forms an elbow. The use of Fuzzy c-means as a grouping method to find out how much influence each data has on each cluster. Because the previous methods used on the same object only grouped it explicitly, without paying attention to the effect of one data on the entire cluster. The grouping was carried out into three clusters or groups based on the parameters of positive cases, recovered, and died of Covid-19 as of 27 April 2021. Cluster 1 only consisted of three provinces, namely West Java, Central Java, and East Java. Cluster 2 DKI Jakarta, and the rest go to cluster 3. It takes a grouping test to determine how accurate the results are.

Abstract

Dental caries is a global metabolic disorder, influenced by complex interactions between the body and microbes, it's caused by prolonged exposure to a low pH environment, leading to demineralized carious lesions. If untreated, it can cause pain and eating difficulties, requiring emergency care and significantly impacting overall quality of life. Diagnosis process can be conducted through physical assessment and analyzing laboratory testing. Image-based artificial intelligence systems, particularly the EfficientNet-B0 model, is suggested as a resolution for classifying dental caries using tooth images. The study's goal is to assess EfficientNet-B0's performance in comparison to other CNN architectures and play a role in advancing medical image classification technology. The original dataset comprising 1554 images was initially collected. After augmentation, the dataset expanded to 6348 images. The data was then divided into three subsets of training, validation, and testing datasets with a distribution ratio of 70:15:15, respectively. From all the evaluated models, the EfficientNet-B0 demonstrated a quite commendable accuracy of 0.98% with overfitting tolerance of less than 2%. Having the same accuracy as the MobileNetV2 (0.98%). Despite its inability to exceed the accuracy achieved by ResNet-50 (0.99%), EfficientNet-B0 accomplished its accuracy level with roughly a quarter of the parameters than ResNet-50 and highger than InceptionV3 (0.97%), highlighting its efficiency in parameter utilization and computational resource management. These findings hold promise for enhancing models and guiding clinical decision-making.

Abstract

This research was conducted to simulate digital image sharpening using the Lusi Richardson deconvolution method. Sharpening was then performed by Lusi richardson deconvolution of the pint spread function of the lens effect. This point spread function is modeled mathematically with a mathematical function approach. The results of the convolution between the Digital Image from a photo of an object are then convolved with the point spread function so as to produce a blurry image. The blurry image is then re-sharpened by deconvolution using the Lucy Richardson convolution method. The results of this deconvolution are then compared with the image of an object photo of reference and then the difference is calculated. The slight difference between the deconvolution result image and the original object photo image indicates that the program is running well. Peak Signal to Noise Ratio (PSNR) Is used to determine image sharpening recovery. The optimum sharpening recovery of deconvolution iteration is obtained in the maximum PSNR value
