Judul: Container Management System REST API Development for NVIDIA DGX A100 Server
Abstrak: Server NVIDIA DGX A100 memiliki konfigurasi yang tidak mudah untuk digunakan oleh peneliti. Penggunaan container pada server dapat memudahkan pengguna baik dari sisi peneliti maupun admin. Selain itu, container memiliki kelebihan pada sisi keamanan, yaitu kegagalan container pengguna tidak berdampak pada kegagalan sistem secara keseluruhan. Sampai saat ini, belum ada sistem manajemen pada server tersebut yang dapat menyesuaikan kebutuhan dan memberikan kemudahan pengguna. Penelitian ini bertujuan untuk mengimplementasikan REST API sistem manajemen container pada server NVIDIA DGX A100 di Institut Pertanian Bogor (IPB). Metode yang digunakan adalah prototyping dengan dua iterasi. Terdapat empat tahap pada metode ini, yaitu komunikasi, perencanaan cepat dan pemodelan rancangan cepat, konstruksi prototipe, serta penyebaran, pengiriman, dan umpan balik. Hasil penelitian ini adalah REST API sistem manajemen container yang menjamin isolasi antar pengguna, keamanan server, dan efisiensi pengelolaan container. Pengujian REST API menggunakan black box testing dengan empat skenario. Hasil pengujian menunjukkan keberhasilan implementasi pada semua endpoint berdasarkan setiap skenario yang ada antara hasil dan masukan sudah sesuai seperti yang diharapkan. Penelitian ini juga dapat dijadikan acuan untuk pengembangan sistem manajemen container pada jenis HPC lainnya., The NVIDIA DGX A100 server has a configuration that is not easy for researchers to use. The use of containers on the server can make it easier for users both from the researcher and admin side. In addition, containers have advantages in terms of security, namely the failure of the user container does not have an impact on the failure of the system as a whole. Until now, there has been no management system on the server that can customize the needs and provide user convenience. This research aims to implement REST API container management system on NVIDIA DGX A100 server at Bogor Agricultural University (IPB). The method used is prototyping with two iterations. There are four stages in this method, namely communication, rapid planning and rapid design modeling, prototype construction, and deployment, delivery, and feedback. The result of this research is a container management system REST API that ensures isolation between users, server security, and container management efficiency. REST API testing uses black box testing with four scenarios. The test results show successful implementation on all endpoints based on each scenario between the results and input are as expected. This research can also be used as a reference for the development of container management systems on other types of HPC.

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: Karakteristik Kimia Kayu Reaksi Ulin (Eusideroxylon zwageri T. et B.)
Abstrak: Reaction wood which formed in hardwood generally has a lower klason lignin content, higher acid soluble lignin content, and higher syringil unit than opposite wood. Ulin wood (E. zwageri) contains high klason lignin and low acid soluble lignin contents which closed to lignin characteristic of softwood. This experimental aimed to study the difference of chemical characteristic of reaction wood (klason lignin content, acid soluble lignin content, and lignin monomer composition) and polysaccharides content which formed in E. zwageri stem. Visually, the reaction wood part was formed in upper side of leaning stem. Klason lignin content in reaction wood part was lower (32.71%) than opposite wood part (33.74%). However, the lowest lignin content was found in the side wood part (28.15%). Lignin of E. zwageri was composed by syringyl and guaiacyl monomer with average of syringil to guaisyl ratio 0,2. Acid soluble lignin content in E. zwageri was very low (0.69%) that positively correlated with the proportion of syringil unit in lignin. Polysaccharide content of reaction wood part (63.66%) was higher than opposite wood part (62.88%), but the highest content polysaccharides presented in the side wood part (64.19%).
