Abstract

Mencuci tangan merupakan hal sangat penting dan sangat dianjurkan untuk menjaga kodisi kesehatan terutama selama masa pandemi wabah covid-19 ini. Untuk pencucian tangan dengan mengggunakan kran yang digunakan secara bersama menimbulkan ke khawatiran bagi masyarakat karena masih membuka peluang untuk penyebaran virus corona melalui pengguna sebelumnya. Sehingga pencucian tangan dengan menggunakan pedal menjadi alternatif yang bisa dimanfaatkan karena pengguna tidak memegang kran air secara langsung, pengguna cukup menginjak pedal yang sudah disediakan pada bahagian bawah wastafel untuk mengaktifkan kran air. Pemberian dua buah wastafel otomatis yang diposisikan di pasar bawan dan kantor wali nagari Bawan kecamatan ampek nagari ini bisa memberikan kebiasaan kepada pengunjung, baik yang berada di pasar ataupun di kantor wali nagari untuk terbiasa mencuci tangan. Selain itu, hal ini juga akan memberikan kontribusi untuk menghambat penyebaran virus corona.

Abstract

DC motors are common in industry due to their simplicity, reliability, and ease of control. However, their speed regulation is sensitive to parameter changes and load disturbances. Variations in parameters like damping coefficients, caused by friction, temperature, and wear, can impair fixed-gain PID controllers. This paper introduces an adaptive fuzzy-PID auto-tuning (AFPAT) scheme to ensure robust speed control amid uncertainties and load disturbances. The controller uses a Sugeno fuzzy system to adjust PID gains online based on speed error (e) and derivative error (de). A second-order DC motor model assesses robustness by varying damping coefficients across five scenarios (4.54 ≤ a1 ≤ 13.62) and a 50 rpm load disturbance at 900 rpm setpoint. Performance measures include steady-state error, overshoot, settling time, and recovery time post-disturbance. Results show the controller achieves zero steady-state error and overshoot with settling times from 2.74 to 4.28 seconds and recovery times from 3.05 to 4.58 seconds. Compared to open-loop, with a steady-state error of 2963, the controller demonstrates robust speed regulation under parameter variations and disturbances.

Abstract

In tropical countries where the rainfall intensity is constantly high, the 3.5 GHz band is a valuable spectrum for the fifth generation (5G) broadband implementation. That is because it provides a balanced trade-off between high capacity and resilience to rain attenuation in tropical climates. However, deploying this band faces regulatory, legal, and technical constrains, especially related to legacy spectrum allocation. This work focuses on key challenges in deploying 3.5 GHz band for 5G network in Indonesia, including regulatory, legal, and technical factors. Indonesia’s new capital city, Ibu Kota Negara (IKN), a smart city with a population projection of 1.9 million by 2045, is used as a case study. A quantitative network planning approach is applied to evaluate coverage and capacity, resulting in an estimated cell radius of 992.4 m, a requirement of approximately 245 gNodeBs, and a total offered throughput of 16.49 Tbps. We analyze the implication of mid-band spectrum characteristics and regulatory limitations on the network deployment planning. The findings are expected to provide a better understanding in spectrum management and network planning, particularly in developing new smart cities.
