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: 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).
