Judul: Potensi Ekstrak Etanol Daun Wungu (Graptophyllum pictum (L.) Griff) pada Tikus Sprague-Dawley Diabetes yang Diinduksi Aloksan
Abstrak: Kadar glukosa dalam darah yang tinggi dapat menyebabkan diabetes mellitus (DM). Penyakit ini dapat diobati dengan pengobatan kimia maupun herbal. Salah satu tanaman herbal yang diduga mampu menyembuhkan DM adalah daun wungu. Pengukuran kadar glukosa dilakukan pada 7 kelompok yaitu kelompok normal (K-1), kontrol negatif (K-2), kontrol positif (K-3), ekstrak etanol daun wungu 25 mg/kg bb (K-4), 50 mg/kg bb (K-5), 100 mg/kg bb (K-6), 200 mg/kg bb (K-7). Uji kadar glukosa dilakukan 2 tahap yaitu tahap perlakuan yang dilakukan untuk mengetahui pengaruh pemberian ekstrak etanol daun wungu terhadap DM dan tahap setelah perlakuan yang dilakukan untuk mengetahui efektivitas ekstrak daun wungu dalam menurunkan kadar glukosa dalam darah. Hewan coba yang digunakan adalah tikus galur Sprague-dawley dengan bobot badan ≥ 200 gram, penelitian dilakukan selama 21 hari. Uji glukosa selama perlakuan menunjukkan pemberian ekstrak etanol daun wungu berpengaruh dalam menurunkan kadar glukosa darah pada tikus diabetes. Hal tersebut ditunjukkan dengan penurunan kadar glukosa dari > 200 mg/dL pada hari ke-4 menjadi < 200 mg/dL pada hari ke-14. Uji glukosa setelah perlakuan menunjukkan K-3, K-5, dan K-6 mengalami penurunan yang tajam. Penurunan K-3 menunjukkan pemberian obat glibenklamid bekerja dengan baik dalam menurunkan kadar glukosa darah pada tikus DM, kadar glukosa K-5 pada menit ke-150 lebih rendah dibandingkan dengan K-6 sehingga dapat diambil kesimpulan K-5 lebih efektif dalam menurunkan kadar glukosa darah puasa pada tikus DM

Judul: Potensi Ekstrak Etanol Daun Wungu (Graphtophyllum pictum (L.) Griff) pada Tikus Sprague-dawley Diabetes yang Diinduksi Aloksan
Abstrak: High level of glucose in blood can cause Diabetes Mellitus (DM). This desease can be treated by either chemical or herbal medicine. One of herbal plant which is expected to heal the desease DM is Wungu leaves. Glucose measurement was conducted to 7 group, normal group (K-1), negative control (K-2), positive control (K-3), ethanol extract of wungu leaves 25 mg/kg bb (K-4), 50 mg/kg bb (K-5), 100 mg/kg bb (K-6), 200 mg/kg bb (K-7). The measurement was conducted in 2 phase namely treatment phase, to determine the effect of ethanol extract of Wungu leaves on DM and post-treatment phase which is to determine the effectiveness of extract of Wungu leaves in dcreasing glucose in blood. The sample animal that is used is Sprague-dawley ratswhich is weighting ≥ 200 gram, the experimental is carried out for 21 days. The result shows that the extract of Wungu leaves effect on decreasing glucose level is blood of diabetes rats. The decreasing of glucose strat from > 200 mg/dL in day 4 to < 200 mg/dL in day 14. Post-treatment phase shows that K-3, K-5, and K-6 decrease significiently. Decreasing on K-3 indicate that glibenklamid is working good in decreasing glucose level in DM rats blood, glucose K-5 on 15th minute is lower than K-6, so it can be conclude that K-5 is more effective in decreasing glucose level on DM rats.

Judul: Implementation of Spatio-Temporal Change Query in Relational Database.
Abstrak: Geographic object changes in various views. Object changes are recorded using a model of static storage. No historical connection between old version data and new version data has been built. For that, a storage model of spatio-temporal queries that can analyze spatio-temporal changes has been developed. The object changes the geometry are grouped according to the taxonomy of Spatio-Temporal Pattern Change. This research has been able to apply the query patterns change including born, expand, merge, contract, split, normal and die. This query based on geometric (area) changes. The implementation of spatio-temporal change queries represents an object changes continuously with easy, change detection is done by comparing two versions of data. Keyword: spatio-temporal change query, spatio-temporal change pattern.
