Abstract

This research is motivated by the urgent need to improve the capability of detecting diseases in citrus plants, which play a crucial role in maintaining agricultural sector productivity. Diseases such as blackspot, canker, and greening can have a serious impact on harvest yields and overall plant health. Therefore, this research aims to enhance the accuracy in classifying diseases in citrus plants by applying a Deep Learning approach. In this study, we chose to adopt the DenseNet-169 architecture and conducted experiments with two different scenarios: one using original features and the other using a combination of features. This method was employed to classify four different classes, namely blackspot, canker, greening, and healthy plants, using an LDI dataset consisting of 3,000 images. This dataset was divided into three parts, namely training, testing, and validation sets. The experimental results indicate that the DenseNet-169 model with the use of feature combination achieved the highest accuracy rate at 96.66%, whereas the model using only original features achieved 91.33%. This significant improvement of 5.33% in accuracy provides strong evidence that the feature combination approach has a highly meaningful positive impact on the model's ability to identify and classify diseases in citrus plants. These findings confirm that the use of feature combinations is a highly effective strategy in improving the model's performance in disease classification tasks in citrus plants.

Abstract

Object detection is a skill that can be taught to a machine with the help of a camera sensor to capture a digital image. By using the YOLO algorithm we can teach machines to detect, for example, humans. Much research in object detection has been carried out previously using different algorithms and methods and also on different objects and images. In this research, a method was carried out to modify the architecture of YOLOv8 in the head section to be used to detect human objects in grayscale images. The training process was carried out 4 times using the default architecture, Model 1, 2 and 3 architecture. With the default model results, the mAP value was 76, Model 1 had an mAP value of 66, model 2 had an mAP value of 81 and model 3 produced an mAP value of 80. From the research carried out modifications The YOLOv8 architecture in the head section can influence the training results and produce a better model than the default architecture which only produces an mAP value of 76. The best results were obtained in model 2 with layers used of 40x40x512xW resulting in a model with an mAP value of up to 81.

Abstract

Pengujian aplikasi adalah proses penting pada pengembangan perangkat lunak. Salah satu cara mempercepat pengujian aplikasi dengan menggunakan teknik pengujian otomatis menggunakan selenium webdriver. Teknik ini menggunakan kode otomatis yang disusun di dalam sebuat test case. Pada test case terdapat langkah pengujian yang terdiri dari banyak locator. Locator merupakan query untuk mengakses element pada website yang merepresentasikan objek yang diakses oleh pengguna seperti tombol, input teks dan lainnya. Locator yang sama bisa digunakan pada test case yang berbeda Pada penelitian sebelumnya, automatisasi pengujian perangkat lunak berbasis website terbukti meningkatkan waktu uji yakni 30 detik lebih cepat dibandingkan proses pengujian secara manual. Namun pada penelitian tersebut tidak dibahas bagaimana proses pembaharuan locator yang efektif ketika terjadi perubahan struktur sistem aplikasi. Penelitian ini bertujuan untuk mengoptimalisasi proses pembaharuan kode automatisasi dengan mengolah data locator menggunakan teknik page object modelling (POM) pada halaman login website. Setiap locator ditempatkan pada satu tempat yang disebut dengan repositori sehingga proses pembaharuan locator dilakukan secara sentralisasi pada repositori tanpa harus mencari dan membuka test case satu per satu.Hasil penelitian menunjukkan efisiensi sebesar 14.28 % lebih cepat jika dibandingkan dengan proses pembaharuan tanpa metode POM

Abstract

The study examines public sentiment on the government's fuel price policy using an experimental approach and Twitter data obtained through API scraping. It applies sentiment analysis methods like Naïve Bayes, SVM, and Majority Voting. SVM achieved 85% accuracy, excelling in identifying negative sentiments, while Majority Voting reached 70% by considering confidence levels. Naïve Bayes struggled with neutral sentiments. They are combining methods to enhance the understanding of public sentiments on fuel price changes. The study highlights sentiment analysis' effectiveness in gauging reactions to fuel policies, with SVM offering more profound insights into sentiments related to fuel price hikes. Challenges remain in identifying neutral sentiments due to social media text brevity. These findings underscore the contextual importance of interpreting sentiment analysis. Leveraging these insights, governments can understand public perceptions better and devise improved communication strategies for sensitive economic policies like fuel price hikes, fostering better government-citizen interactions. The study aims to guide stakeholders in comprehending public perspectives within public policy, emphasizing the relevance of sentiment analysis for policy evaluation.
