Abstract

The voice coil is a vital speaker component, producing sound through electromagnetic vibrations. Generally, commercially available voice coils do not meet standard quality specifications, especially in terms of copper quality and adhesive strength. This problem often leads to issues such as coil burning or breakage during operation. On the other hand, ordering custom voice coils through manual winding processes requires considerable time. This study aims to address these limitations by designing an automated coil winding device that employs Pulse Width Modulation (PWM) techniques to control the speed of a DC motor, enabling the production of voice coils with specifications and durability tailored to specific needs. An Arduino Nano microcontroller controls the system and consists of a BTS 7960 motor driver, a Direct Current (DC) motor, an optocoupler sensor, a rotary encoder, a 4x4 keypad, and an LCD display with an I2C interface. Coil durability testing was conducted using an ohmmeter and an amplifier with a transformer ranging from 20A 45V to 30A 45V. The testing results indicate that coils produced with the automated winder can be adjusted to approach the 8-ohm specification, with a tolerance of 0.1 to 0.3 ohms, suitable for speaker requirements. The comparison results show that commercial voice coils exhibit resistances below 8 ohms, with the lowest resistance measured at 4.9 ohms for larger coils. During power testing, coils with a diameter of 35.5 mm and copper wire diameters of 0.20 mm and 0.23 mm broke when tested with a 20A 45V amplifier. In contrast, commercial coils remained stable up to an input power of 372 W and output power of 273 W, although a burning odor was detected. These findings indicate that the copper quality in commercial coils is superior in resisting amplifier power up to 30A 45V compared to coils produced with the automated device.

Abstract

Teknologi Internet Of  Things dalam penelitian ini dimanfaatkan pada Pembangkit Listrik Tenaga Surya (PLTS) (Studi Kasus : Prodi Teknik Elektro Universitas Trunojoyo Madura) sebagai sistem monitoring daya baterai dan kontrol beban. Semua sistem tersebut dibangun dengan tujuan mempermudah pengguna dalam mengelola konsumsi daya yang digunakan sekaligus mencegah kerusakan baterai sehingga masa pakai baterai dapat bertahan lebih lama dan penggunaan PLTS menjadi lebih optimal. Semua sistem tersebut dirancang menggunakan beberapa komponen yang saling terintegrasi dengan fungsi masing-masing seperti Raspberry sebagai pengolah data, smartphone sebagai interface, dan sensor aktuator sebagai input output. Dari hasil pengujian akurasi monitoring didapatkan nilai error rata-rata sebesar 1,56 %. Setelah memastikan sistem memiliki tingkat akurasi yang tinggi, dilakukan pengujian charge-discharge secara real time selama 7 hari yang menunjukan bahwa sistem bekerja sesuai tujuan penelitian yang dibuktikan dengan tidak adanya penggunaan daya melebihi batas standar SOC baterai yang digunakan sebesar 30%. Sedangkan untuk pengujian sistem kontrol didapatkan bahwa koneksi wifi memiliki rata-rata delay paling cepat selama 10,30 s, provider A 11,17 s, dan provider B 12,60 s.
