Judul: Containerization of Water Quality Monitoring and Controlling System Web Application Using Docker
Abstrak: Budi daya udang vaname mengalami kenaikan produksi sebesar 250% pada tahun 2024 menjadi sebesar 1.290.00 ton. Kenaikan produksi udang tersebut dapat berpengaruh pada pengelolaan limbah tambak udang. Diperlukan sistem pemantauan dan pengendalian kualitas air untuk membantu pembudi daya dalam mengolah air. Aplikasi web dan mobile digunakan untuk memantau data kualitas air secara langsung yang dikirimkan oleh sensor IoT ke peladen edge computing. Kontainerisasi menggunakan Docker membantu dalam konsistensi dependensi dan konfigurasi untuk deployment. Tahapan analisis kebutuhan, perancangan, implementasi, pengujian, dan evaluasi dilakukan untuk mempermudah deployment. Perancangan kontainerisasi telah berhasil dilakukan dengan membuat konfigurasi file Dockerfile dan Docker Compose yang dibagi untuk lingkungan pengembangan dan lingkungan produksi. Implementasi dilakukan di satu lingkungan pengembangan dan tiga belas lingkungan produksi yang kemudian diuji untuk dipilih spesifikasi yang cocok untuk deployment. Hasilnya, spesifikasi dengan CPU satu core dan memori satu gigabita dengan distribusi sistem operasi Fedora Linux merupakan referensi spesifikasi minimum yang cocok untuk dijadikan peladen deployment aplikasi web., Vaname shrimp farming experienced a 250% increase in production in 2024 to 1,290,00 tons. The increase in shrimp production can affect the management of shrimp pond waste. A water quality monitoring and controlling system is needed to assist farmers in treating water. Web and mobile applications are used to monitor live water quality data sent by IoT sensors to edge computing servers. Containerization using Docker helps in consistency of dependencies and configuration for deployment. Stages of requirement analysis, design, implementation, testing, and evaluation are performed to facilitate deployment. Containerization design has been successfully done by creating Dockerfile and Docker Compose configuration files that are divided for the development environment and production environment. Implementation was carried out in one development environment and thirteen production environments which were then tested to select suitable specifications for deployment. As a result, the specification with one core CPU and one gigabyte memory with Fedora Linux operating system distribution is a suitable reference minimum specification to be used as a web application deployment server.

Judul: Optimalisasi Backend Monitoring Kolam
Budidaya Udang Berbasis Water Quality Monitoring and Controlling System.
Abstrak: Limbah pencemar air yang memenuhi standar kualitas menjadi tujuan penting untuk meningkatkan produksi budidaya udang super intensif. Dalam upaya mengurangi beban limbah dan juga memenuhi pedoman umum pembesaran udang, maka dirancang suatu Instalasi Pengolahan Air Limbah (IPAL) menggunakan teknologi Recirculating Aquaculture System (RAS) dan pendekatan Plasma Finebubble. Teknologi ini diimplementasikan dengan menerapkan sistem pemantauan dan pengendalian (WQMCS) IoT untuk kolam budidaya udang. Penelitian sebelumnya mengembangkan aplikasi ¬backend dengan menggunakan Laravel dan dianalisa mampu dioptimalkan. Penelitian ini akan dikembangkan kembali sistem pemantauan dan pengendalian dengan menggunakan framework Yii2, kemudian membandingkan kinerjanya dengan aplikasi yang telah dibuat sebelumnya. Metode yang digunakan untuk pengembangan aplikasi adalah metode Agile Scrum dan pengukuran kinerja dilakukan dengan mengukur fungsional sistem, tingkat kesalahan, waktu respon, dan permintaan per detik. Sistem berhasil dioptimalkan dengan aktifnya semua endpoint serta mengurangi tingkat kesalahan sampai 0%, waktu rata-rata respon 34,31ms, dan 5,39 permintaan per detik lebih banyak., Waste water pollution that meets quality standards is an important goal to increase the production of super-intensive shrimp farming. In an effort to reduce the waste load and also meet the general guidelines for shrimp rearing, a Wastewater Treatment Plant (IPAL) using Recirculating Aquaculture System (RAS) technology and Plasma Finebubble approach was designed. This technology is implemented by applying an IoT monitoring and control system (WQMCS) for shrimp farming ponds. Previous research developed a backend application using Laravel and analyzed that it can be optimized. This research will redevelop the monitoring and control system using the Yii2 framework, then compare its performance with the application that has been made before The method used for application development is the Agile Scrum method and performance measurement is done by measuring system functionality, success rate, response time, and requests per second. The system was successfully optimized with all endpoints active and improved 100% success, 34.31ms average response time, and 5.39 more requests per second.

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
