Judul: Aplikasi Augmented Reality Penunjuk Ruangan Kampus Institut Pertanian Bogor
Abstrak: Aplikasi navigasi dapat membantu seseorang untuk mencapai tujuannya dengan lebih cepat dan efisien. Pada umumnya, navigasi menggunakan GPS sebagai alat bantunya. Akan tetapi, GPS seringkali tidak berfungsi dengan baik pada kondisi dalam ruangan terutama pada lokasi kampus IPB yang memiliki banyak ruangan. Tujuan dari penelitian ini adalah untuk membuat prototipe aplikasi Augmented Reality (AR). Aplikasi dibuat menggunakan Vuforia SDK. Interaksi AR yang digunakan pada aplikasi ini menggunakan image target sebagai penanda suatu lokasi sehingga pengguna aplikasi lebih mudah mendapatkan informasi lokasi ruangan. Dari hasil evaluasi pengguna didapatkan 108 dari 180 jawaban responden menyatakan bahwa aplikasi ini memenuhi user expectation sebagai aplikasi AR.

Judul: Rekayasa Augmented Reality Mobile Campus Tour Institut Pertanian Bogor
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: Karakteristik Carboxymethyl Chitosan Dengan Variasi Konsentrasi NaOH
Abstrak: Carboxymethyl chitosan is chitosan derivative product obtained from chemical modification. CMCh were made by alkalization process and carboxymethylation process. Factors that affect CMCh characteristics were excess sodium hydroxide in alkalization process, ratio between chitosan and monochloroacetic acid, and carboxymethylation temperature. The objectives of this research were to study the NaOH effect to CMCh characteristics, to learn process of making CMCh, to set the proper concentration of NaOH, and to analyze CMCh characteristics. CMCh yields were 110.72%-114.22%. CMCh pH value were 3.74-4.31. The optimum NaOH concentration to obtain the best CHCh was 10 M. Percentage of CMCh moisture content was 10.70%-11.42%. Ash content and nitrogen content of CMCh were 0.49%-0.50% and 4.52%-4.81%. CMCh viscousity was 8.25 cps. Percentage of CMCh solubility was 61.61%-91.50%. The different functional groups from chitosan which observed in CMCh were C=O group, CH group from alkene functional group, C−O group, and C−O−C group.
