Abstract

Indonesia possesses the world's largest aquatic resources, with 17,504 islands and 6.49 million square kilometers of sea. Located in the coral triangle, Indonesia is home to diverse marine life, including vital coral reefs. However, these reefs face threats from climate change, pollution, and human activities, endangering biodiversity and coastal communities. Therefore, monitoring and preservation are crucial. This study evaluates various augmentation methods for classifying underwater coral reef images using Convolutional Neural Networks (CNNs). Effective augmentation methods are essential due to the unique characteristics of these images. The methodology includes testing different augmentation methods, epoch parameters, and CNN parameters on a coral reef image dataset. Five optimization algorithms (AIWPSO, GA, GWO, PSO, and FOX) are compared. The highest accuracy, 95.64%, is achieved at the 10th epoch. AIWPSO and GA show the highest average accuracies, 93.44%, and 93.50%, respectively, with no significant performance differences among the algorithms. Statistical analysis using the Wilcoxon test indicates a significant difference between training and validation accuracy (p-value = 0.0020). These findings underscore the importance of selecting augmentation methods that align with the characteristics of each optimization algorithm to enhance classification performance. The results provide valuable insights into improving the quality and diversity of input data for classification algorithms in underwater image analysis. They highlight the necessity of matching augmentation methods to specific optimization algorithms to boost accuracy and effectiveness significantly. Future research should explore additional augmentation methods and optimization algorithms further to enhance the robustness and accuracy of underwater image classification.

Abstract

This research analyzes governance and public participation in infrastructure megaprojects in Indonesia, such as MRT Jakarta and Trans-Java Toll Road, by comparing national and international practices. Megaprojects frequently face challenges in the form of cost overruns, schedule delays, social conflicts, and significant environmental impacts. This study aims to evaluate the effectiveness of implemented governance and public participation models, and compare them with international best practices. The study uses a literature approach and international case analysis to explore governance models, such as Public-Private Partnership (PPP) and more inclusive public participation approaches. The results show that transparent, accountable governance that involves communities from the outset can enhance public acceptance and project sustainability. Comparative analysis with international case studies provides insights into adapting best practices to the Indonesian context. Strategic recommendations include financing innovations, utilization of digital technology, and a holistic approach that considers social, economic, and environmental impacts.Keywords: Governance, Public Participation, Megaprojects, Infrastructure, Sustainability

Abstract

Bogor Regency has experienced significant land cover changes due to urbanization, population growth, and infrastructure expansion. This study predicts land cover changes in 2026 using a random forest model based on classified Sentinel-2 satellite imagery. The model was trained with data from 2017, 2020, and 2023 and evaluated using 2-fold time-series cross-validation, with an accuracy of 87.96%, Kappa 0.8131, and F1-Score 0.8752. The prediction results show an increase in built-up area from 748.02 km² (2017) to 953.89 km² (2023) and is estimated to reach 976.84 km² in 2026—especially in Pamijahan and Jonggol. On the other hand, agricultural areas decreased from 652.53 km² to 541.11 km² and are predicted to decrease again to 530.33 km², threatening local food security. Tree cover areas also decreased from 1,509.12 km² (2017) to 1,385.34 km² (2023) but are expected to increase to 1,413.42 km² in 2026 due to the reforestation program. These findings emphasize the importance of sustainable land planning to balance development with environmental conservation for the sustainability of the ecosystem and the welfare of the Bogor community.   Kabupaten Bogor mengalami perubahan tutupan lahan yang signifikan akibat urbanisasi, pertumbuhan penduduk, dan ekspansi infrastruktur.

Abstract

Addressing the challenge of predicting earthquake-induced building damage, this study proposes the innovative use of Deep Neural Networks (DNN) as a solution. Focusing on optimizing predictive models, the research evaluates the effectiveness of various optimizers - ADAM, SGD, RMSprop, and Adagrad - coupled with adjustments in the learning rate to determine the most efficient configuration. The experiment was conducted to compare the performance of each optimizer in predicting post-earthquake building damage, a critical issue in disaster mitigation. The results demonstrate that ADAM significantly outperforms other optimizers, achieving the highest accuracy of up to 90.50% at a learning rate of 0.001, with RMSprop as its closest competitor. While SGD and Adagrad yielded lower accuracies, SGD showed improvement with higher learning rates. The variance analysis confirmed that the choice of optimizer significantly impacts model performance, with the p-value indicating strong statistical significance for optimizers (1.23E-09), whereas the learning rate had no significant impact (p-value 0.56098964). These findings underline the importance of selecting the appropriate optimizer to enhance the accuracy of DNN models for building damage prediction, a crucial aspect in emergency response planning and earthquake disaster mitigation efforts. This research contributes significantly to the development of more accurate predictive models, which are essential in minimizing the risks of earthquake disasters.

Abstract

Location Based Service (LBS) is a service on smartphones that functions as a navigation device based on the user's position to determine the location where the user is. LBS utilizes GPS capabilities in finding geolocation information and sometimes using Google maps to display a complete map of the location. But the results of previous research studies Google Map does not give shortest and accessible routes. Furthermore, to improve work of LBS, Floyd Warshall algorithm is used because the algorithm has the principle of optimality in calculating the total of all routes optimally. According to data recorded by the Ministry of Religion of the Republic of Indonesia there have been 1,304 Mosques in the City of Semarang, but with this much data it should be easier to find places of worship for Muslims. Most mosques that are visited are mosques on the highway because it is more visible even though there are many other mosques that can be accessed. By using the White Box and Black Box tests, finding shortest path to find places of worship in the city of Semarang can be given accurately. The result was the Floyd Warshall algorithm could provide shortest path route and it was more accessible better than Google Map navigation.

Abstract

Klasifikasi huruf alfabet Bahasa Isyarat Indonesia (Bisindo) menjadi fokus penting dalam bidang computer vision. Variasi posisi tangan, pencahayaan, dan kemiripan antar huruf menyebabkan kesulitan dalam mengenali pola visual Bisindo. Penelitian ini menerapkan Convolutional Neural Network (CNN) berbasis Transfer Learning (TL) untuk menganalisis pengaruh hyperparameter terhadap kinerja model menggunakan metode Coordinate Descent Search. Empat arsitektur diuji, yaitu EfficientNetB0, EfficientNetB1, ResNet18, dan ResNet50, pada dataset Bisindo yang berisi 6.760 citra tangan huruf A–Z. Optimasi dilakukan secara sekuensial pada lima parameter: batch size, learning rate, dropout rate, optimizer, dan epoch. Hasil menunjukkan learning rate optimal antara 0.0001–0.0003 dengan batch size kecil (16) efektif untuk model ringan, sedangkan ResNet50 optimal pada batch size 64. Model ResNet50 menghasilkan akurasi 93,17%, precision 93,26%, recall 93,15%, dan F1-score 93,13%. Hal ini menunjukkan bahwa TL efektif untuk klasifikasi Bisindo, dan arsitektur lebih dalam seperti ResNet50 memberikan performa terbaik.
