Judul: Mashup Informasi pada Situs Blog Institut Pertanian Bogor Berbasis Wordpress Menggunakan Web Service
Abstrak: Wordpress merupakan salah satu content management system (CMS) untuk pengembangan aplikasi web. Situs web Institut Pertanian Bogor (IPB) memiliki subdomain bagi mahasiswa, dosen, atau lembaga kemahasiswaan untuk memiliki sebuah blog berbasiskan Wordpress. Isi dari Wordpress biasanya memiliki struktur yang sama dan isinya dapat dipanggil dalam format tertentu melalui web service yang sudah tersedia di dalamnya. Pada penelitian ini akan diintegrasikan isi dari total 20 blog Wordpress di situs IPB, yang terdiri dari lima blog mahasiswa dan lima blog lembaga kemahasiswaan, serta sepuluh blog dosen. Web service yang digunakan yaitu JSON API, sebuah API yang tersedia untuk Wordpress. JSON API mengijinkan sisi klien mendapatkan dan memanipulasi isi wordpress menggunakan HTTP request. Isi dikembalikan dalam data berstruktur JSON yang akan mengalami praproses sehingga dapat diindeks oleh Sphinx Search, sebuah library tambahan untuk membangun sebuah sistem pencari. Hasil evaluasi sistem pencari yang didapatkan yaitu nilai mean average precision dari 9 query yang diuji sebesar 0.48, yang berarti sekitar 48% dokumen yang didapatkan oleh sistem berdasarkan query, relevan terhadap query.

Judul: Pengembangan Agregator Berita IPB
Abstrak: The rapid growth of Internet led to the diversity of the data. An example of this diversity is the sites of faculty and department at Bogor Agricultural University (IPB), which not all of newest news of the sites can be retrieved using Rich Site Summary (RSS). This would complicate the collection of recent news. To overcome this, the method that be used is mashups. The mashup was created using the Application Programming Interface (API). In this study, the API used is the Google Search API, which is will be used to search related news.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
