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: 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: 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.
