Developing telecommunications infrastructure is vital for national advancement, improving connectivity to accelerate information flow and access to public services. Effective base station planning prioritizes maximizing network coverage in densely populated areas. However, traditional visualization methods often fall short in identifying regions with the highest population density. This study addresses this gap by applying a sector expansion algorithm to select optimal base station locations within the most densely populated sectors, achieving more balanced network coverage. Using Indonesia’s population data and administrative boundaries, optimal base station locations are determined with DBSCAN and K-Means clustering algorithms. The network’s reach is then enhanced through sector expansion to increase coverage in areas with high population density by selecting new base station locations based on the densest sector around a primary station. The candidate station is positioned at a distance of three-quarters of twice the radius of the primary station, optimizing coverage while remaining close to existing network resources. The evaluation compares population coverage before and after sector expansion, assessing connectivity between base stations and distribution efficiency. Results show that sector expansion increased population coverage on Lombok Island from 15.94% to 99.14%, with the most populated base station covering up to 34,274 people, enhancing distribution efficiency.

If you want to fully understand the ecosystem surrounding AI-driven robotics in pediatric neurorehabilitation, you need to carefully look at many interconnected aspects and think critically about what they mean. We address this review to facilitate an in-depth analysis of the effective integration of advanced technologies, such as artificial emotional intelligence and interactive reinforcement learning, into rehabilitation practices. By critically assessing each element, from the psychological dynamics of patient engagement to the technical intricacies of real-time adaptive learning systems, we can better understand their pivotal roles in enhancing therapeutic efficacy. Moreover, the inclusion of natural language processing and facial expression analysis warrants careful consideration, as it sets the stage for more nuanced interactions between robots and pediatric patients, thereby fostering a therapeutic environment that is both responsive and empathetic. A thorough examination not only highlights the potential benefits but also the ethical and practical challenges associated with these technologies. By putting these different parts into a critical framework, we ensure that we have a complete picture of the opportunities and limitations in this new field. Our ultimate goal is to improve rehabilitation outcomes for kids with neurological problems while keeping an eye out for any unintended effects.

Abstrak— Akuakultur udang vaname membutuhkan sistem aerasi yang efektif untuk menjaga kadar oksigen terlarut, memastikan bahwa kualitas air tetap sesuai untuk perkembangan udang. Motor DC umumnya digunakan untuk aerasi karena manfaat efisiensinya; namun, kontrol manual kurang berhasil dalam menangani kondisi kolam yang dinamis. Pendekatan fuzzy-PID adalah sistem yang menggabungkan reaksi cepat kontrol PID dengan kemampuan adaptif logika Fuzzy, yang memungkinkan motor DC untuk secara otomatis mengubah kinerja berdasarkan kadar oksigen di kolam. Pengujian menunjukkan bahwa pengontrol PID dengan Fuzzy mengungguli PID konvensional dalam waktu pengendapan, overshoot, undershoot, IAE, ISE, dan ITAE sambil memiliki waktu naik yang lebih lambat. Pengontrol PID dengan Fuzzy unggul dalam waktu pengendapan, overshooting, undershooting, IAE, ISE, dan ITAE. Pengontrol PID Fuzzy mempertahankan stabilitas overshoot dan undershoot di seluruh proses kontrol. Kontrol Fuzzy-PID dalam sistem aerasi dimaksudkan untuk meningkatkan efisiensi energi, menghemat biaya pengoperasian, dan menjaga kadar oksigen dalam rentang yang dapat diterima, sehingga meningkatkan hasil kolam dengan pengeluaran yang lebih efisien.
