Judul: Sistem Informasi Geografis Ruang Kuliah Kampus IPB Dramaga Berbasis Mobile dengan Platform Android OS
Abstrak: Institut Pertanian Bogor (IPB) which is located in Dramaga, Bogor, West Java has a wide area and has a lot of lecture halls. This has caused many residents of IPB, especially new students have difficulties knowing every location of the lecture halls. Today, GIS technology has been integrated with mobile devices such as Android to ease developer to build an interactive mobile GIS application. The purpose of this study is to develop a mobile-based geographical information system for lecture halls in IPB Dramaga with Android platform that can provide location information using linear sequential model. this research resulted in a mobile GIS application that can display a map from Google Maps which has been added with locations of lecture halls in IPB selected by the user. This application also provide information about distance and signpost between the lecture halls locations and the user location. Another feature is to display information of the lecture halls as images of the lecture halls, faculties, and the building where the lecture halls exist.

Judul: Sistem informasi geografis pencarian ruang kuliah kampus IPB Darmaga
Abstrak: IPB has the building architecture which is almost equal to a fairly wide area and sometimes a lot of academicians are confused and have difficulty in finding the intended lecture room. In this research, we built a web-based system using the system development life cycle which presents geographic information that can help facilitate the academicians in search of lecture room at IPB. The geographic information system is built using Pmapper. The results of this research is a system which displayed room information in a table with function of filtering, searching, paging, delete, edit, add data, and in the form of a map with the features on Pmapper with function of coordinates, legends, searching, zooming to extents, back, forward, zoom to selected, zoom in, zoom out, pan, identify, select, tool tip, refresh folder, point of interest, download, and export to CSV / PDF. Based on the test results, this system has worked well in accordance to the user needs to facilitate them in searching lecture room at the IPB Darmaga campus.

Judul: Penambahan α-Tocopherol sebagai Antioksidan dalam Pengencer Tris Kuning Telur Spermatozoa Kucing pada Suhu 4 ⁰C
Abstrak: Stres oksidatif pada sperma terjadi selama pengolahan semen dan berdampak pada kerusakan sperma. Antioksidan α-Tocopherol merupakan salah satu antioksidan yang termasuk ke dalam kelompok antioksigen. Antioksidan ini dapat mengurangi aksi radikal bebas dan menurunkan stress oksidatif pada sperma. Penelitian ini bertujuan menguji efektivitas penambahan α-tocopherol pada pengencer tris-kuning telur terhadap kualitas semen cair yang berasal dari kauda epididimis kucing. Kauda epipidimis kucing didapatkan dengan metode kastrasi. Kauda epididimis kemudian dipisah dan dicacah untuk mendapatkan spermatozoa kucing. Semen dengan motilitas >70% diencerkan pada kelompok pengencer tris kuning telur (TKT), tris kuning telur dengan α-tocopherol 0.1% (TKT+T-0.1%), tris kuning telur dengan α-tocopherol 0.2% (TKT+T-0.2%), dan tris kuning telur dengan α-tocopherol 0.3% (TKT+T-0.3%). Semen cair disimpan selama 4 hari (H0-H4) pada suhu 4 °C, kemudian dilakukan evaluasi kualitasnya (motilitas, viabilitas, abnormalitas dan membran plasma utuh sperma) setiap 24 jam. Hasil penelitian menunjukkan kualitas semen cair tidak berbeda signifikan pada H0 (P>0.05), tetapi penambahan α-tocopherol secara umum meningkatkan kualitas semen pada H4 pascapreservasi. Berdasarkan hasil penelitian, kelompok pengencer TKT+T-0.1% adalah perlakuan terbaik.
