Judul: Pengembangan Sistem Rotasi Peta pada Perangkat Mobile tanpa Sensor Magnetometer
Abstrak: Due to the improvement of technology, the function of mobile phone has changed a lot. Nowadays, mobile phone is used not only for communication, but also to support the user’s activity. Many mobile phones now have Operating System (OS) and sensors like GPS and magnetometer. GPS is a sensor that can be used to identify any location, including the location of the user, while magnetometer can be used to identify direction. With data that come from GPS and magnetometer, we can build a navigation application that can rotate its map according to the rotation of the user. Meanwhile, in the Android Compability Definition Document point 1.6 until 2.2, Google have requirements for mobile phones to have GPS and magnetometer sensors if they want to use Android OS. But, since the release of 2.3.3 OS, Google has changed its requirements, allowing any mobile phones to have Android OS without having the magnetometer sensor. The objective of this research is to build an navigation application that can rotate without using magnetometer sensor. The value of the rotation degree is taken from last two position. To stabilize the value, Exponential Smoothing is used in filtering process. This system also use Haversine method to recognize whether the user is walking or driving/riding.

Judul: Pengembangan Sistem Aplikasi Mobile Untuk Visualisasi Pola Sekuens Pada Titik Panas (SIMPANTAS).
Abstrak: Kebakaran lahan dan hutan sering terjadi di Indonesia dalam beberapa tahun terakhir. Indikasinya mampu diketahui dengan pendataan pola-pola titik panas yang terjadi sebelumnya. Sistem untuk pendataan titik panas berbasis aplikasi web dan mobile pun sudah dikembangkan dan berfungsi optimal. Namun dalam penerapannya kadang mengalami kesulitan karena kurangnya kemudahan terhadap penggunaan akses dalam meraih informasi, baik lokasi saat dibutuhkan karena sistem tersebut hanya mampu dipergunakan pada perangkat komputer ataupun laptop. Maka dari itu penelitian ini mengembangkan sistem visualisasi pola titik panas berbasis perangkat berjalan (mobile) dengan menggunakan library SPMF dan Google Maps API pada environment Android. Penelitian ini juga mengembangkan fitur visualisasi pola titik panas secara realtime, sehingga hasil penelitian dapat memvisualisasikan pola sekuens titik panas.

Judul: Buprenorphine and Fischer-344 Rats Post-operative Stress Levels: Impact on Serum Corticosterone Levels.
Abstrak: The use of laboratory animals in experiment often requires surgical operations. Post-operative condition often associated with pain and stress. Preemptive analgesia and post operative treatment with buprenorphine can reduce post operative pain and stress and prevent prolonged pain. Therefore, the aim of the present study was to test the hypothesis that pre operative treatment of buprenorphine reduces stress and suppresses the pre-operative serum corticosterone levels in Fischer 344 rats. A total of 14 adult male Fischer 344 (F344/Sca) rats permanently catheterized in artery carotis communis were used. During 94 hour post-operatively the blood sample was collected at specific time point using Accusampler®, an automated blood sampling. Corticosterone levels were quantified with ELISA method using sheep polyclonal antibody to corticosterone. Buprenorphine is effective as pre-emptive analgesia in F344 strain. However the dose is higher than what has been reported in Sprague Dawley strain. Buprenorphine 1.0 mg/kg significantly suppressed serum corticosterone levels immediately after rats regain consciousness. Rats in buprenorphine 1.0 mg/kg group were protected from post operative body weight loss and reduced water intake compare to control, nutella, and buprenorphine 0.4 mg/kg group. Quantification of fecal corticosteroid metabolites failed to detect stress in present study.
