Abstract

This research aims to design and develop a DC motor-based mini water pump prototype by implementing the Engineering Design Method. The primary objective is to enhance water circulation and cleanliness in mini aquariums, addressing the issue of rapid water turbidity caused by minimal circulation and the absence of an automatic filtration system that necessitates frequent manual cleaning. The prototype is controlled by an Arduino Uno R3 and utilizes a DC motor regulated by an L298N motor driver. The system operates entirely based on time-based logic without sensors, in which the pump activates for ten minutes and deactivates for five minutes repeatedly. Testing results indicate that the prototype functions stably according to the programmed schedule and effectively maintains water flow in aquariums with a capacity of less than 8 liters. The success of this automatic circulation system significantly delays the water clouding process and reduces the frequency of manual maintenance. Given its relatively affordable cost, this device is concluded to be a practical solution for maintaining the ecosystem and hygiene of mini household aquariums.

Keywords: Mini water pump, DC motor, Arduino Uno, automatic circulation, mini aquarium, Engineering Design Method.

 

Abstrak

Penelitian ini bertujuan untuk merancang dan membangun prototipe mesin pompa air mini berbasis motor DC dengan menerapkan Engineering Design Method. Tujuan utamanya adalah meningkatkan sirkulasi dan kebersihan air pada akuarium mini, mengatasi masalah air cepat keruh akibat minimnya sirkulasi dan tidak adanya sistem filtrasi otomatis yang menuntut pembersihan manual rutin. Prototipe ini dikendalikan oleh Arduino Uno R3 dan menggunakan motor DC yang diatur dayanya oleh driver motor L298N. Sistem ini beroperasi sepenuhnya berdasarkan logika waktu, tanpa sensor, di mana pompa menyala selama sepuluh menit dan mati selama lima menit secara berulang. Hasil pengujian menunjukkan bahwa prototipe mampu bekerja secara stabil sesuai program waktu dan efektif menjaga aliran air pada akuarium berkapasitas di bawah 8 liter. Keberhasilan sistem sirkulasi otomatis ini secara signifikan memperlambat proses pengeruhan air dan mengurangi frekuensi pembersihan manual. Dengan biaya yang relatif terjangkau, alat ini disimpulkan sebagai solusi praktis untuk menjaga ekosistem dan kebersihan akuarium mini di rumah tangga
