Abstrak: Navigation is a complex problem that requires a set of skills and tools. Because of the complexity, a navigator will be more focused on the process and tools rather than their surrounding. This problem can be solved using augmented reality (AR), a derivation of virtual reality which augments real world with virtual objects. With AR, we can mark a real world location using virtual markers and put relevant information, which is automatically processed by a computer, of that location. This will simplify and reduce the effort of navigation process. Today, many smartphones have enough computing power to run an augmented reality application. This research presents a prototype of augmented reality mobile campus tour in Bogor Agricultural University on Android smartphone. The application is able to give the user estimated bearing and distance of the locations relative to user’s current location. Distance and bearing are computed using Haversine formula to reduce the computation process. To reduce noise in accelerometer and magnetometer values, exponential smoothing is used with accelerometer smoothing factor = 0.2 and magnetometer smoothing factor = 0.5.

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: Sifat Fisik dan Kimia Daging Kelinci Hyla Hycole dan New Zealand White.
Abstrak: Hyla dan hycole merupakan kelinci pedaging unggul dengan laju pertumbuhan dan tingkat prolifik yang tinggi. Kedua kelinci tersebut masih relatif baru dikembangkan di Indonesia, sedangkan kelinci new zealand white telah adaptif dan populer sebagai kelinci pedaging. Penelitian ini bertujuan untuk membandingkan kualitas daging kelinci hyla, hycole dan new zealand white berdasarkan sifat fisik dan kimia. Kelinci mulai dipelihara pada kisaran rataan bobot 2 000-2 256 g hingga mencapai bobot akhir 2 700-3 500 g dengan pemberian kualitas pakan yang sama (protein 17.8% dan energi 4098 kcal). Otot longissimus dorsi digunakan sebagai bahan uji sifat fisik, sedangkan daging dari setiap potongan komersial digunakan untuk uji sifat kimia. Hasil uji sifat fisik menunjukkan bahwa rataan nilai pH akhir daging kelinci hyla, hycole dan new zealand white adalah 5.67, sedangkan untuk susut masak 38.27-39.72%, keempukan 3.10-3.70 kg cm-2 dan DMA 23.75-28.18%. Hasil uji sifat kimia menunjukkan nilai rataan persentase kadar air 75.00-77.26%, abu 1.08-1.14%, lemak 3.29-4.05%, protein 18.15-19.64% dan gross energy 1 327.00-1 521.20 kcal kg-1. Kelinci hyla, hycole dan new zealand white memiliki kualitas daging yang sama baiknya.
