Abstract

Pada bulan Februari 2021 di Cilegon, penyebaran Virus Corona (COVID-19) akibat sentuhan benda di sekitar kita sangat mengkhawatirkan sehingga untuk mengurangi penyebarannya dibutuhkan sebuah sistem yang bekerja secara otomatis tanpa sentuhan tangan. Fokus penelitian ini adalah merancang alat pengunci pintu tanpa sentuh berbasis Arduino yang memanfaatkan sensor ultrasonik, sensor suara, magnetic switch, serta kunci slot dengan metode perancangan Pahl dan Beitz. Sehingga dengan adanya alat ini diharapkan mampu mengurangi penyebaran Virus Corona melalui pengunci pintu. Hasil penelitian didapati sensor ultrasonik dapat bekerja dengan baik mendeteksi jarak, magnetic switch memiliki batas pembacaan sejauh 10mm, serta sensor suara yang memiliki kepresisian rendah. Kesimpulan produk dapat digunakan sebagai sarana pencegahan Virus Corona dengan tidak menyentuh kunci slot, namun memiliki kepresisian yang rendah pada sensor suara menyebabkan dibutuhkan lebih dari 1 tepukan agar sensor dapat mendeteksinya.

Abstract

Utilizing alternative energy as an effort to use energy needs to be done. One is energy harvesting, which is capturing minute amounts of energy from one or more surrounding energy sources, collecting and storing them for later use. There are examples of uses in harvesting energy from vibrations, which are carried out using piezoelectricity as a converter into electrical energy. A piezoelectric-based electrical energy harvesting device has been designed using a cantilever method from mechanical pressure from humans climbing stairs. This research uses an experimental method where there are variations in the load given by humans of 55 Kg, 65 Kg, and 75 Kg to provide a force on an energy harvester that has four piezoelectric circuits installed, which are installed in series and parallel totaling 38 piezoelectric units. , where the four circuits have a number of piezoelectrics of 10, 8, 10, and 8 piezoelectrics on each side. The resulting voltage will later be rectified using a rectifier bridge until it is temporarily stored in the capacitor. As obtained from the calculation results, the voltage values for each load are 7.762 mV, 11.103 mV, and 17.55 mV, respectively.

Abstract

This study focuses on designing a touch-free door lock system based on Arduino, utilizing ultrasonic sensors, sound sensors, magnetic switches, and slot locks, following the Pahl and Beitz design methodology. The aim is to develop a reliable system that enhances convenience and reduces the need for physical contact with door locks. The results indicate that the ultrasonic sensor performs effectively in detecting distances, while the magnetic switch operates within a maximum reading range of 10 mm. However, the sound sensor demonstrated low accuracy, requiring multiple claps for successful detection. The findings suggest that the developed product functions as intended, though the limitations of the sound sensor highlight the need for further improvements to optimize precision and responsiveness.

Abstract

Machines in manufacturing areas often cause noise. The noise comes from machine tools such as lathes, milling machines, grinder machines, and other tools that cause sound and vibration so they are prone to causing physical and psychological disorders. This study was to determine and analyze the noise level in three areas and ten points in the manufacturing room of The Job Training and Development Center Serang by the Regulation of the Minister of Manpower and Transmigration of the Republic of Indonesia Number PER.13/MEN/X/2011 with the maximum noise limit that has been set is 85 dBA. As for the results of the ten points, there is a point that exceeds the threshold value, namely at point 6 (85.8) dBA in the lathe area. Every operator in the manufacturing room that has a noise level that exceeds the threshold value must wear personal protective equipment in the form of earplugs or ear muffs that have been provided by the workshop to reduce the noise level.
