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: Prototype Mobile GIS Kampus IPB Darmaga Menggunakan J2ME, GeoServer, dan Jaringan Wi-Fi
Abstrak: Bogor Agricultural University has a vast land area and identical building shape consisting of nine faculties and thirty eight departments. Many university students, especially freshman who are not familiar with the entire building’s site campus, in particular the location of lecture halls. In order to resolve the issue, a dynamic and accessible Geographic Information Systems for IPB Darmaga campus needs to be built. The aims of this research is to create and display a dynamic map for IPB campus as a mobile-based GIS. The system prototype used J2ME, GeoServer, and the campus Wi-Fi network used for location-based services. The prototype was built as a three-tier system that has three components: the client, the web server, and the database server. The client serves as a presentation tier for running the application. The web server consists of GeoServer as web map server, and Apache web server. GeoServer serves as an application to store and process geospatial data and sends a response in the form of maps and its information to client. A PHP web application serves as the application for processing location data based on SSID Wi-Fi sent by client. System provides functions to select and display map layers, and there are additional menus such as Zoom in, Zoom out, Refresh, Reset view, GetFeatureInfo, the menu to request information about specific features shown on the map, and MyLocation, the menu used to identify user’s location based on Wi-Fi network.

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.
