Abstract

Bimbingan dan konseling sangat dibutuhkan terutama dalam dunia pendidikan untuk mendukung kepercayaan  diri murid dalam menghadapi  tantangan-tantangan yang dialami semasa di sekolah. Namun, di SMA Islam 1 Sleman, masih ditemukan  Beberapa siswa memilih untuk memendam masalah yang dialami sehingga enggan menemui guru BK pada jam sekolah dan Pencatatan data saat ini masih dilakukan secara manual dengan mencatat di buku atau lembaran kertas. Maka diberikan solusi lain bagi siswa yang lebih nyaman saat berkonsultasi secara daring.  Oleh karena itu, penelitian ini bertujuan untuk membuat aplikasi E-Counseling berbasis mobile  dibangun menggunakan framework flutter untuk platform mobile dan PHP untuk website, database MySQL, dengan integrasi REST API. Pengembangan perangkat lunak menggunakan metode waterfall, sedangkan perancangan aplikasi menggunakan Entity Relationship Diagram (ERD) untuk memodelkan struktur basis data. Pengujian fungsional menerapkan dengan teknik Black-Box testing untuk memastikan semua fitur  berjalan maksimal. Hasil penelitian ini adalah aplikasi bimbingan dan konseling siswa dilengkapi dengan fitur-fitur konsultasi Chat,  penjadwalan, keluhan siswa, data siswa, dan rekap konsultasi.

Abstract

Conventional catfish aquaculture in Indonesia often suffers from inefficient feed management due to manual feeding, leading to feed waste, poor water quality, and inconsistent fish growth. To address these limitations, this study develops a user-friendly Internet of Things (IoT)-based automatic catfish feeding system that integrates automation, real-time monitoring, and simplified configuration. The system employs an ESP32 microcontroller as the core hardware and Firebase as a cloud-based backend for instantaneous data synchronization. A key innovation is the inclusion of a local web server on the ESP32, enabling farmers to configure Wi-Fi networks directly through a browser without reprogramming the device. The companion mobile application, “Feedy Finn,” built using Flutter, allows users to remotely set feeding schedules, control operations manually, and monitor device performance in real time. Black Box testing demonstrated stable two-way communication with a latency of under 500 milliseconds and a feed dispensing consistency exceeding 95%, reducing feed waste by approximately 20% compared with manual methods. The results confirm that the system enhances operational efficiency, ensures precise feeding intervals, and simplifies device setup, making it accessible to small and medium-scale fish farmers. Beyond technical performance, the study contributes to sustainable aquaculture by minimizing environmental impact and promoting digital inclusion in rural communities. This integration of affordability, usability, and automation highlights the system’s potential as a scalable model for advancing smart aquaculture and supporting Indonesia’s transition toward technology-driven fisheries.
