Abstract

The innovation of the health protocol system for the prevention of the corona virus with an energy source of piezoelectric as independent electricity, namely the use of the concept of energy harvesting, converts the vibration or pressure generated by the footrests into electrical energy. The prototype system uses a piezoelectric ladder to generate power and a charging module to recharge from the battery. The power required is 60 watts. The charging aims to activate the entire system, namely by washing hands and sensors detecting masks and measuring body temperature which are all carried out in parallel. The camera sensor is able to distinguish the use of masks, so that your photos will be accurate and consistent. The Raspberry Pi controller communicates with the website server, which in turn controls various aspects of the system. The results of the process will be integrated with IoT and stored in a database, and the results will be displayed on a website as a monitoring process. If the system determines that the required health protocols are complete, the door will open automatically. The camera sensor accuracy is averaged out to be 98.5% accurate. In testing the whole system with around 40 kg of mass, which results in an average output voltage of 3.18 V and a current of 1.38 A and a foot step 3.517, 50 kg, the output voltage was 3.88 V, Current was 2.08 A and a step of 2,298 feet and 60 kg, resulting in an average voltage of 5.28 V, a current of 3.42 A and an average pedestrian frequency of 1.494.

Abstract

Pada pengujian seakeeping miniatur kapal cepat gerak zig-zag mengalami overshoot sebesar 13,5° melewati jalur yang telah ditentukan 20°, sehingga tidak terwujud konsistensi kestabilan kapal dan kemiringan arah sudut yang berakibat pada hasil pengambilan data. Pada penelitian ini berfokus pada pembuatan sistem kontrol otomatis untuk mengendalikan gerak rudder. Metode yang digunakan yaitu PID dengan tuning Ziegler-Nichols. Sistem ini menggunakan teenseyduino sebagai mikrokontroler untuk mengontrol dua servo motor sebagai rudder kapal, HWT 905 sebagai sensor dan motor DC sebagai laju kecepatan pada miniatur kapal cepat. Sensor HWT905 akan mendeteksi kemiringan arah pada badan kapal akibat gelombang. Berdasarkan hasil pengujian didapatkan parameter gain yang mampu memberikan hasil terbaik yaitu pada saat nilai Kp = 1,1, Ki = 3,3, Kd = 0,09, didapatkan nilai error steady state sebesar 15% dan overshoot sebesar 3°. Nilai rise time yang diperoleh sebesar 3 detik dan settling time diperoleh sebesar 5 detik yang menunjukkan bahwa gerak dari motor servo mulai stabil pada waktu tersebut.
