RANCANG BANGUN SYSTEM MONITORING DAN CONTROLING ALAT PEMBERI PAKAN IKAN DAN PENGGANTI AIR OTOMATIS

Introduction

Rancang bangun system monitoring dan controling alat pemberi pakan ikan dan pengganti air otomatis. Otomatisasi pakan ikan & penggantian air akuarium/budidaya. Sistem ini gunakan NodeMCU, Arduino, sensor turbiditas & ultrasonik. Kontrol via aplikasi Blynk untuk perawatan ikan optimal.

Abstract

Memelihara ikan di akuarium adalah salah satu hobi pecinta ikan hias, memberi pakan ikan dan mengganti air keruh serta membersihkannya untuk menciptakan kondisi yang baik untuk ikan. Dalam Peraturan Menteri Kesehatan. Menurut Keputusan No. 416/MENKES/PER/IX/1990 tentang permintaan dan pengendalian air, batas maksimum kekeruhan air bersih yaitu 25 NTU (Nepholometric Tutbidity Unit). Ada beberapa hal yang kurang di akuarium saat ini, seperti mengganti air dan memberikan makan secara manual. , tujuan penelitian ini adalah untuk membuat dan merancang suatu alat dengan harapan dapat meningkatkan dan mendukung kualitas perawatan ikan di akuarium, maupun untuk budidaya ikan pada sektor perikanan. Agar sistem dapat berjalan, mikrokontroler NodeMCU ESP8266 v3 harus terkoneksi ke internet dan aplikasi blynk. Aplikasi blynk berfungsi memonitoring dan mengontrol pakan, dan mikrokontroler akan membaca data sehingga alat dapat berjalan dan memberikan pakan ke akuarium melalui kontrol aplikasi Blynk ataupun secara terjadwal/otomatis. Mikrokontroler Arduino mega 2560 berfungsi mengatur system kerja alat penggantian air otomatis sesuai program yang telah di buat, Sensor turbidity mendeteksi kekeruhan air untuk menentukan kapan harus mengganti air. Jika data pada sensor turbidity mendeteksi kekeruhan air lebih dari 25 NTU, relay 1 terbuka dan relay 2 tertutup sehingga pompa pengurasan air di akuarium beroperasi. Sensor ultrasonik berfungsi mendeteksi kedalaman air pada akuiarium yang telah di tentukan pada program yaitu lebih dari 16 cm untuk mencegah air habis terkuras. Saat kedalaman air maksimum tercapai, relay 2 terbuka untuk mematikan pompa pengurasan air dan relay 1 tertutup untuk menghidupkan pompa pengisian air . Saat mengisi air, sensor ultrasonik mendeteksi jarak maksimum ketinggian air dan mengisi air sesuai jarak yang telah ditentukan yaitu kurang dari atau sama dengan 7 cm

Review

The submitted work, titled "RANCANG BANGUN SYSTEM MONITORING DAN CONTROLING ALAT PEMBERI PAKAN IKAN DAN PENGGANTI AIR OTOMATIS," proposes the design and construction of an automated system for aquarium maintenance. The primary objective is to address the manual effort involved in feeding fish and changing turbid water, aiming to improve fish health and convenience for hobbyists, with potential applicability in aquaculture. The system leverages a combination of NodeMCU ESP8266 for internet connectivity and remote control via the Blynk application for feeding, and an Arduino Mega 2560 for orchestrating the automatic water replacement mechanism. Sensors, specifically a turbidity sensor and an ultrasonic sensor, are employed to monitor water quality (NTU) and level, respectively, enabling intelligent decision-making for water exchange operations. This research presents a highly practical and useful solution for a common problem faced by aquarium owners. The integration of two crucial maintenance tasks – automatic feeding and water changing – into a single system is a significant strength. The use of IoT technology (NodeMCU and Blynk) for remote monitoring and control provides flexibility and convenience, allowing users to manage their aquariums from anywhere. The inclusion of a turbidity sensor to detect water quality based on a defined NTU threshold (25 NTU) is a commendable feature, ensuring that water changes are performed only when necessary and proactively maintaining a healthy environment for the fish. Furthermore, the ultrasonic sensor acts as a critical safety measure, preventing excessive water draining or overflow during the refilling process, demonstrating thoughtful system design. While the abstract provides a detailed description of the system's components and operational logic, it notably lacks information regarding experimental validation or performance evaluation. The paper would greatly benefit from presenting concrete results, such as the accuracy and reliability of the sensors under various conditions, the consistency of the feeding mechanism, the duration and efficiency of the water change process, and the overall system's robustness in a real-world aquarium setting. Discussion on power consumption, potential failure modes (e.g., internet connectivity loss for NodeMCU), and a comparison with existing automated solutions would also enhance the work's contribution. Future iterations could explore scalability for larger aquaculture setups, cost analysis, and long-term maintenance requirements to provide a more comprehensive understanding of the system's practical implementation and impact.
