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: Mercury Toxicity and It’s Effect on Histopathology Change of Nile Tilapia (Oreochromis niloticus).
Abstrak: Nile tilapia (Oreochromis niloticus) is one of fish species that oportunity to contaminated with mercury. The effects of pollutants can damage living organisms organs and can cause death. The effects caused mercury had acute or chronic character. The aims of this study are to determine threshold and acute toxicity of mercury chloride (HgCl2) of Nile tilapia (Oreochromis niloticus), to assess the effect of mercury chloride (HgCl2) on several biometric parameters (survival, growth rate of average daily weighted, liver condition, bile and reproductive variability of Nile tilapia (Oreochromis niloticus), assess the level of damage to the histological structure of the gills, liver and kidney of Nile tilapia (Oreochromis niloticus) caused mercury chloride (HgCl2) exposure. This study was conducted from February to June 2013. Nile Tilapia (Oreochromis niloticus) were used in this study were female with average weight 20 grams or 11-13 cm length range. Toxicant materials used in this study was mercury chloride (HgCl2). Fish were reared in each aquarium 60x40x30 containing 48 liters of water. This study consists of three stages: a preliminary test, acute test, and sub-chronic test. To determine the changes in biometric condition of tilapia approximated by measuring the survival rate (SR), the growth rate of average daily weight , the content of mercury in the fish organs, hepatosomatic index (HSI), the relative bile volume (VER), gonadal soamtic index (IKG), fecundity and oocit diameter, tissue damage caused by mercury in fish organs by making histological preparations stained with hematoxylin and eosin. The median lethal concentration (96 hr, LC50) of Mercury Chloride was calculated as 1,64 mgL--1.The survival rate was highest in the control treatment (46,67 %) . Mercury chloride with concentration 0.196 mgL--1 show significant effect to changes HSI and relative bile volume, and oocyte diameter of Nile tilapia (p < 0,05). Mercury chloride with a concentration of 0,164 mgL-1 and 0,196 mgL-1 have not a significant effect on the growth rate of weight, gonadal somatic index and fecundity of Nile tilapia (p > 0,05). Mercury chloride cause damage to gills (hyperplasia, hypertrophy, proliferation and neukrosis), liver (hyperplasia, hemorhage, shrinkage of hepatocytes, proliferation and neukrosis) and kidney (hyperplasia, hemorrhage, shrinkage of the glomerulus, proliferation and neukrosis).
