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 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.
