Abstract

Waste management is an important challenge in protecting the environment and public health. Improperly managed waste can cause pollution and hinder the recycling process. This study aims to classify waste based on images by optimizing three deep learning architectures, namely EfficientNetB3, MobileNetV2, and ResNet50, to determine the model with the best performance. The dataset comes from the Kaggle platform, consisting of 4,650 images in six categories: battery, glass, metal, organic, paper, and plastic. The research stages include preprocessing, data augmentation, model development, and evaluation using accuracy, precision, recall, and F1-score metrics. The results show that EfficientNetB3 with the Adam optimizer achieved the best performance with 93% accuracy, followed by ResNet50 with 91%, while MobileNetV2 ranged from 70–73% depending on the optimizer. Variations in optimizers were found to affect model performance, while data augmentation improved generalization capabilities, especially in classes with limited samples. This research confirms the potential of deep learning methods in supporting automatic waste classification systems and provides a basis for the development of technology-based waste management systems in the future.

Abstract

Fossil fuel power plants are still used as a source of energy around the world and have a significant impact on emissions and environmental pollution. To reduce these emissions, renewable energy offers a solution that can be applied in future housing. This study proposes a simulation using HOMER to determine the most cost-effective composition of hybrid renewable energy systems in housing. This simulation can combine photovoltaic (PV) systems, wind power (WP), and a converter that functions to change DC to AC from PV to obtain an alternating current (AC) system. The hybrid combination of PV and WP proves to be the most appropriate and economical choice at the research location. The results of the study showed that the installation of a hybrid system in housing, with an initial investment cost of IDR 107,474.43 million and an annual operating cost of IDR 22,540.23 million, is 41% lower than conventional fossil fuel-based systems. Research data shows that the project's payback period is estimated to be around 11 years. These findings can be recommendations for similar systems in regions with similar contours and geography. Apart from that, positive monetary impacts can provide incentives for policymakers to implement similar hybrid systems, thereby contributing to the goal of global emissions neutralization.

Abstract

Background: Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan pengetahuan, keterampilan, dan kemandirian masyarakat Desa Banyumas dalam memanfaatkan limbah pucuk tebu dan kotoran ternak menjadi kompos organik melalui penerapan teknologi tepat guna. Metode: Program dilaksanakan melalui pendidikan masyarakat, pelatihan, difusi teknologi, dan pendampingan, dengan introduksi mesin pencacah pucuk tebu serta praktik pembuatan kompos berbasis bahan lokal. Hasil: Hasil kegiatan menunjukkan adanya peningkatan pemahaman masyarakat mengenai pengelolaan limbah pertanian, meningkatnya efisiensi proses pencacahan bahan baku, dan terselenggaranya praktik pengomposan yang lebih terstruktur. Program ini berkontribusi positif terhadap pengurangan limbah pertanian dan membuka peluang pemanfaatan kompos organik bagi kebutuhan pertanian masyarakat. Ke depan, evaluasi mutu kompos secara laboratorium dan pendampingan pemasaran masih diperlukan agar program benar-benar berkelanjutan
