Abstract

In the era of public information disclosure, public information management is essential for transparency, accountability, and citizen participation. This study assesses eight Public Information Management Officers (PPID) in Central Java, Indonesia, utilizing 21 variables measured by a Multi-Factor Evaluation Process (MFEP) based on Data Lifecycle Management (DLM) and Socio-Technical Systems (STS). Data was collected using Likert-scale questionnaires, and performance was assessed using Evaluation Weight Value (EWV) and Total Evaluation Weight (TEW). The results suggest that technology-related indicators outperformed human competency and regulatory compliance. "Use" and "Disposal" were the DLM phases with the worst performance, demonstrating deficiencies in data accountability and infrastructure. In STS, the "People" dimension lagged, emphasizing the need for capacity building. The findings indicate that, while digital infrastructure is robust, governance and human resource development require strengthening. Strategic improvements in underperforming sectors are suggested to strengthen public information governance.

Abstract

Skin cancer is one of the most prevalent types of cancer worldwide, with early detection playing a critical role in improving patient outcomes. In this study, we propose a deep learning model based on LeNet-7 combined with adaptive boosting (AdaBoost) to classify skin lesions as either benign or malignant using the International Skin Imaging Collaboration (ISIC) dataset. We evaluate the proposed model alongside other well-established deep learning architectures, such as residual network (ResNet), VGGNet, and the traditional LeNet model, through various performance metrics including precision, recall, F1-score, specificity, Matthew’s correlation coefficient (MCC), area under the receiver operating characteristic curve (AUC-ROC), and testing accuracy. Our results demonstrate that the proposed model (LeNet-7+AdaBoost) significantly outperforms the other models, achieving a testing accuracy of 91.3%, precision of 0.92, recall of 0.91, and AUC-ROC of 0.93. The model successfully addresses issues of overfitting and generalization, providing a robust solution for skin cancer classification. However, some misclassifications of visually similar benign and malignant lesions highlight areas for future improvement. The proposed model shows promise in real-world medical applications and paves the way for further research into optimizing deep learning models for skin cancer detection.

Abstract

Tujuan dari penelitian ini yakni untuk meningkatkan keaktifan siswa dan juga hasil prestasi belajar siswa yang bisa dilihat dari nilai ketuntasan siswa kelas IX-B SMP N 1 Karangrejo semester 2 tahun pelajaran 2018/2019 dengan adanya pendekatan model pembelajaran contextual teaching and learning menulis narative text. Hal ini dilatarbelakangi dengan rendahnya nilai siswa pada materi tersebut dikelas. Oleh karen aitu diperlukan penerapan pendekatan model pembelajara. Salah satu model pembelajaran yang sudah banyak diterapkan yakni metode Contextual Teaching and Learning (CTL). Metode yang digunakan dalam penelitian yakni penelitian tindakan menggunakan 2 siklus dan masng – masing siklus ada 4 tahapan. Hasil penelitia menunjukkan jika penerapan model pembelajaran CTL dapat meningkatkan keaktifan siswa dan juga nilai ketuntasan siswa kelas IX-B SMP N 1 Karangrejo semester 2 tahun pelajaran 2018/2019 dalam belajar menulis narative text. Pada siklus I nilai ketuntasan siswa mencapai 73,3% dan pada siklus II nilai ketuntasan siswa meningkat menjadi 90,0%.

Abstract

The fish farming group in Cepiring District, Kendal Regency, faces a major issue of high fish feed costs, which amount to approximately IDR 4,500,000 per harvest cycle. Dependence on external suppliers causes unpredictable price fluctuations, hindering the increase in farmers' income. Therefore, it is essential to find a solution that can significantly reduce production costs. The objective of this community service program is to reduce fish feed production costs by developing a solar-powered pellet machine, which can independently produce fish feed using renewable energy. The service partner in this program is the Fish Farming Group in Cepiring District, Kendal. The method of this service includes problem analysis, development of solar-powered pellet machine technology, technical training on how to use and maintain the machine, and the implementation of digital marketing to improve market access. The expected outcomes are a 40-50% reduction in fish feed costs per harvest cycle, increased independence for farmers in producing their own fish feed, and improved overall production efficiency. This program is expected to support the sustainability of environmentally friendly fish farming and enhance the economic independence of fish far.
