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 Modul Frontend Forum Tani Pada Aplikasi Web Digital Tani Menggunakan Metode Prototyping
Abstrak: Pertanian merupakan salah satu komoditas andalan di Indonesia, kendati demikian masalah dapat muncul ketika petani tengah melakukan pekerjaannya. Berdasarkan studi literatur, forum diskusi online dinilai sebagai wadah yang baik sebagai tempat berdiskusi bagi petani. IPB telah mengembangkan aplikasi Digital Tani yang merupakan aplikasi untuk membantu menyelesaikan masalah-masalah pertanian. Penelitian ini akan mengembangkan modul forum tani pada aplikasi web Digital Tani dari sisi frontend menggunakan metode Prototyping. Hasil dari penelitian ini merupakan modul yang memiliki fitur utama forum seperti membuat, melihat, dan melaporkan thread dan juga fitur manajemen forum oleh admin. Hasil pengujian pada iterasi terakhir menggunakan metode blackbox testing menunjukkan semua fitur pada modul forum tani sudah berjalan dengan baik. Modul forum tani diharapkan dapat menjadi wadah bagi petani untuk melakukan diskusi seputar pertanian dengan sesama petani atau dengan para pakar dan penyuluh yang ada di IPB melalui aplikasi web Digital Tani., Agriculture is one of the mainstay commodities in Indonesia, however problems can arise when farmers are doing their jobs. Based on a literature study, online discussion forum are considered to be a good forum for discussions for farmers. IPB has developed the Digital Tani application which is an application to help solve agricultural problems. This research will develop forum module on the Digital Tani web application from the frontend side using the Prototyping method. The results of this study are modules that have the main forum features such as creating, viewing, and reporting threads as well as forum management features by the admin. The test results in the last iteration using the blackbox testing method show that all the features on the forum module have been running well. The forum module is expected to be a place for farmers to have discussions about agriculture with fellow farmers or with experts and instructor at IPB through the Digital Tani web application.

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.
