Judul: Integrasi Sistem Digital Tani dengan Sistem Cyber Extension IPB menggunakan Arsitektur Microservice
Abstrak: Penggunaan teknologi pada media komunikasi dikalangan pelaku pertanian di Indonesia masih terbatas. Adanya Cyber Extension IPB sebagai portal pertanian berbasis web masih belum cukup untuk mendukung komunikasi di sektor pertanian di Indonesia sehingga diciptakan Digital Tani sebagai aplikasi Portalharga dan KMS (Knowledge Management System) untuk membantu pertanian di Indonesia. Namun, kedua sistem tersebut belum sepenuhnya terintegrasi satu sama lain. Penelitian ini melanjutkan dari hasil penelitian Digital Tani sebelumnya, dengan tujuan mengintegrasikan sistem Digital Tani dengan sistem informasi Cyber Extension IPB dengan arsitektur microservice, sehingga pengguna hanya perlu menggunakan satu akun untuk mengakses kedua platform tersebut. Sistem ini dibangun dengan menggunakan Extreme Programming. Hasil dari penelitian ini berhasil membuat kedua sistem berjalan dengan sempurna, hal ini diujikan dengan mencoba seluruh fungsi yang diimplementasikan dengan menggunakan user acceptance test criteria yang telah didefinisikan., The use of technology in communication media among agricultural actors in Indonesia is still not accessible by anyone. The existence of Cyber Extension IPB as a web-based agricultural portal is still not enough to support communication in the agricultural sector in Indonesia, so Digital Tani was created as a Portalharga application and knowledge management system for helping agricultural sector in Indonesia. However, the systems are not fully integrated each other. This research continues from the results of previous Digital Tani research, with the aim of integrating the Digital Tani system with the IPB Cyber Extension information system, so that users only need to use one account to access the two platforms. This system was built using an extreme programming method. The results of this research succeeded in making both systems run perfectly, this was tested by trying all the functions that were implemented using the defined user acceptance test criteria.

Judul: Pengembangan Backend Pengelolaan Artikel untuk Aplikasi Digital Tani
Abstrak: IPB sebagai kampus yang terus mendukung pertanian Indonesia telah melakukan banyak inovasi sebagai upaya untuk memajukan pertanian Indonesia. Salah satu bentuk upayanya dengan mengembangkan aplikasi Digital Tani. Pada aplikasi digitani terdapat fitur artikel untuk memudahkan petani dalam mendapatkan informasi. Saat ini pembuatan artikel dilakukan di Wordpress dan aplikasi digitani berjalan di arsitektur yang berbeda. Penelitian ini akan mengembangkan backend pengelolaan artikel untuk mengintegrasikan artikel yang ada pada Wordpress dengan aplikasi Digitani. Pengembangan menggunakan metode prototyping dan hasil dari penelitian ini adalah backend berbasis REST API dengan response yang dihasilkan adalah JSON. Pengujian dilakukan dengan internal testing menggunakan metode blackbox dan semua fungsi berhasil berjalan dengan sesuai sehingga dapat dikatakan pengembangan berhasil dilakukan., IPB as a campus that continues to support Indonesian agriculture has made many innovations as an effort to advance Indonesian agriculture. One of the efforts is to develop the Digital Tani application. In the Digitani application there is an article feature to help farmers in obtain information. Currently, the creation of articles is done on Wordpress and the Digitani application runs on a different architecture. This study will develop an article management backend to integrate existing articles on Wordpress with the Digitani application. The development uses the prototyping method and the result of this research is a REST API-based backend with the resulting response is JSON. Testing was carried out by internal testing using the blackbox method and all functions were running successfully so that it can be said that the development was successful.

Judul: Separation of Neodymium from U3Si2/Al Fuel Plate for Burn-Up Determination
Abstrak: Neodymium is a common fission product produced in nuclear fission reactions. Neodymium in this study was chosen as a burn-up indicator for U3Si2/Al fuel element plates because the neodymium isotope is a stable fission product with a fairly high yield. Some procedures were carried out to separate neodymium, starting with the separation of cesium isotopes (137Cs, 134Cs) through the precipitation method, then separation of uranium isotopes (235U, 238U) and plutonium isotopes (239Pu, 238Pu) with Dowex 1x8 ion exchange resin, and separation of neodymium (Nd), samarium (Sm), as well as cerium (Ce) with Dowex 1x4 ion exchange resin. The Cs recovery reached 99.95%. The U and Pu isotopes resulting from the separation are subjected to an electrodeposition process and the weight of each isotope can be measured with an alpha spectrometer. The separation results of Nd from Sm and Ce have been proven using an XRF spectrometer. The neodymium isotopes separation was corrected using the standard addition method, and an average total Nd content of 2.4 ppm was obtained in the PEB U3Si2/Al bottom solution. It is hoped that this separation method can be applied in determining burn-up of nuclear fuel.
