Judul: Pengembangan Backend Forum Tani pada Digital Tani dengan Metode Prototyping
Abstrak: Indonesia adalah negara agraris yang sebagian besar masyarakatnya bermata pencaharian sebagai petani. Kurangnya edukasi yang merata mengenai pertanian mengakibatkan sulitnya pemahaman tentang permasalahan baru yang dihadapi petani. Adanya forum online dapat membantu petani dalam mendiskusi permasalahan baru dengan lingkup yang lebih luas. Tani Center IPB mengembangkan aplikasi Digital Tani sebagai one stop solution untuk masalah pertanian Indonesia. Penelitian ini bertujuan untuk mengembangkan backend forum tani pada aplikasi Digital Tani dengan metode prototyping. Sistem dikembangkan dengan menggunakan framework Laravel dengan arsitektur Model, View, Controller (MVC). Hasil pengembangan diuji menggunakan blackbox testing dan telah berhasil memenuhi Minimum Viable Product (MVP) dengan iterasi yang dilakukan sebanyak 2 kali., Indonesia is an agricultural country where most of the people make a living as farmers. The lack of equitable education about agriculture makes it difficult to understand the new problems faced by farmers. The existence of online forums can help farmers in discussing new problems with a wider scope. Tani Center IPB developed the Digital Tani application as a one stop solution for Indonesian agricultural problems. This study aims to develop a farmer forum backend on the Digital Tani application using the prototyping method. The system was developed using the Laravel framework with Model, View, Controller (MVC) architecture. The results of the development were tested using blackbox testing and had successfully met the Minimum Viable Product (MVP) with 2 iterations.

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.
