Judul: Perancangan dan Implementasi Container dengan Konsep Swarm dan Metode Ingress Load Balancing Menggunakan Docker
Abstrak: Masjid Alumni IPB ingin mengembangkan suatu sistem yang disebut masjid berbagi. Masjid berbagi merupakan suatu sistem berbasis aplikasi web dan mobile dan terhubung ke cloud. Masjid berbagi dibuat untuk pengelolaan dan berbagi informasi tentang kegiatan masjid-masjid. Semua aplikasi dan informasi disimpan pada server masjid berbagi sehingga server masjid berbagi harus dapat melayani permintaan oleh masjid-masjid. Pada penelitian ini bertujuan untuk perancangan dan implementasi container menggunakan docker dengan menerapkan docker swarm dan load balancing ingress. Penelitian ini dibagi kedalam empat tahap utama yaitu komunikasi (analisis lingkungan), penerapan container, pengujian dan analisis. Pada penelitian dilakukan perbandingan penerapan dengan satu sampai lima container untuk mengetahui pengaruh banyak container dengan respon server, request yang dapat dilayani dan throughput. Hasil penelitian menunjukkan semakin banyak container lebih baik daripada hanya menggunakan satu container karena dapat meningkatkan respon time dan banyak sucess request. Tetapi banyaknya container harus tetap diperhatikan.

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: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
