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: Mobile Application Development for Shrimp  Pond Water Quality Monitoring and Control System
Abstrak: Udang merupakan salah satu komoditas budidaya perairan di Indonesia. Nilai ekspor sebesar 1.719.172.000 USD pada tahun 2019, membuat udang memiliki potensi besar untuk meningkatkan devisa negara. Potensi yang besar tersebut diikuti dengan resiko yang besar seperti pencemaran lingkungan dan kegagalan budidaya. Hal tersebut menjadi alasan dilakukannya pengembangan aplikasi front-end mobile Water Quality Monitoring and Controlling System menggunakan framework Flutter. Melalui aplikasi yang dikembangkan, petambak udang dapat memantau dan mengontrol kualitas air berdasarkan data sensor yang ditanamkan pada kolam tambak udang. Aplikasi ini dikembangkan menggunakan metode agile dengan framework Scrum. Diawali dengan User Requirement Analysis untuk perencanaan product backlog yang berisikan fitur yang dibutuhkan dan pelaksanaan sprint. Sprint dilakukan melalui 4 tahap, yaitu sprint planning, daily scrum, sprint review dan sprint retrospective. Sprint yang dilaksanakan selama 89 hari (4 sprint) telah menghasilkan aplikasi dengan fitur utama Monitoring, Maintenance dan Aktivasi perangkat IoT., Shrimp is one of the aquaculture commodities in Indonesia. The export value of 1,719,172,000 USD in 2019, makes shrimp has great potential to increase foreign exchange. This great potential is followed by great risks such as environmental pollution and cultivation failure. This is the reason for developing a front-end mobile Water Quality Monitoring and Controlling System application using the Flutter framework. Through the developed application, shrimp farmers can monitor and control water quality based on sensor data embedded in shrimp ponds. This application was developed using agile method with Scrum framework. It begins with User Requirement Analysis for product backlog planning which contains the required features and sprint implementation. Sprints are carried out through 4 stages, namely sprint planning, daily scrum, sprint review and sprint retrospective. The sprint that was carried out for 89 days (4 sprints) has produced an application with the main features of Monitoring, Maintenance and Activation of IoT devices.

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
