"Diabetes melitus tipe II merupakan salah satu jenis diabetes melitus dengan populasi penderita mencapai 90-95%. Salah satu gejala yang ada pada penderita diabetes tipe ini adalah terjadi kenaikan kadar gula dalam darah setelah 2 (dua) jam makan. Strategi terapi yang digunakan salah satunya dengan menggunakan agen penghambat enzim α-glukosidase. Beberapa jenis tanaman dari suku Clusiaceae telah diteliti secara ilmiah terbukti memberikan aktivitas sebagai antidiabetes dan antioksidan. Garcinia daedalanthera Pierre merupakan salah satu tanaman dari suku Clusiaceae. Penelitian sebelumnya menyatakan bahwa ekstrak daun Garcinia daedalanthera Pierre mempunyai aktivitas sebagai antioksidan dan dapat menghambat aktivitas α-glukosidase. Penelitian ini bertujuan untuk mengisolasi dan mengidentifikasi senyawa dengan aktivitas antioksidan dan penghambatan terhadap α-glukosidase secara in vitro. Isolasi dilakukan dengan kromatografi kolom. Hasil fraksinasi ekstrak etil asetat diperoleh subfraksi dengan potensi antioksidan dan penghambatan terhadap α-glukosidase. Pemurnian subfraksi EA6-1 diperoleh isolat dengan IC50 antioksidan 5,618 μg/mL dengan metode DPPH, 1,441 μg/mL dengan metode FRAP dan IC50 penghambatan terhadap α-glukosidase sebesar 2,502 μg/mL. Hasil elusidasi struktur isolat dari data spektroskopi UV-Vis, IR, MS, 1H-NMR, 13C-NMR, dan 2D-NMR menunjukkan bahwa isolat tersebut adalah suatu glikosida biflavonoid, Fukugiside.

Diabetes mellitus type II is one type of diabetes mellitus that most commonly found, reaching 90-95% of the population. At this type, there are many patients with the kind of symptom, increase in blood sugar levels after two hours of meal. Inhibition of α-glucosidase is one of the therapeutic strategy. Some species of Clusiaceae have been scientifically proven to provide as antidiabetic and antioxidant activity. Garcinia daedalanthera Pierre is one of the plants of this genus. At the previous studies, the extract of Garcinia daedalanthera Pierre folium has antioxidant activity and may inhibit the activity of α-glucosidase. This study aims to isolate and identify compounds with antioxidant activity and inhibition of α-glucosidase in vitro. Isolation performed by column chromatography. Fractionation of ethyl acetate extract obtained subfraction with antioxidant potential and inhibition of α-glucosidase. Purification of subfraction EA6-1 acquired isolate with antioxidants IC50 of 5.618 μg/mL (DPPH method), 1.441 μg/mL (FRAP method) and IC50 inhibition against α-glucosidase by 2.502 μg/mL. The spectrum of UV-Vis, IR, MS, 1H-NMR, 13C-NMR, and 2D-NMR showed that the isolate is biflavonoid glycoside, Fukugiside."

"Pada proses analisa video, permasalahan deteksi dan identifikasi objek adalah masalah yang sering dijumpai dan menjadi akar masalah yang menyebabkan analisa video masih belum bisa dilakukan secara real time dan diaplikasikan untuk hal yang kompleks. Oleh sebab itu, telah banyak metode yang dikembangkan untuk mengatasi permasalahan tersebut. Salah satu metode yang digunakan untuk identifikasi objek adalah Gaussian Bayes Classifier. Pada skripsi ini dirancang dan disimulasikan identifikasi objek yang berada di tangan dengan menggunakan Gaussian Bayes Classifier. Parameter correctness percentage digunakan untuk menguji performansi dari identifikasi objek (kaleng Green Sands, kaleng Pocari Sweat, dan Biore) yang berada di tangan. Hasil simulasi menunjukkan bahwa hasil pengidentifikasian objek yang memiliki ketepatan pengidentifikasian yang paling paling baik adalah ketika mengidentifikasi antara tidak ada objek dengan objek kaleng Green Sands yang memiliki nilai rata ? rata correct percentage yang mencapai 89% untuk setiap percobaannya dan 94,6% untuk setiap percobaannya saat pengidentifikasian tidak ada objek.

In video analysis process, problem in object detection and object identification is a common problem and the root problem that causes the video analysis still can?t be used in real time and applied to complex condition. Therefore, many methods have been developed to overcome these problems. One of the methods which is used for object identification is Gaussian Bayes Classifier method. In this thesis is designed and simulated object identification in hand using Gaussian Bayes Classifier. Correctness percentage parameter is used to test the performance of in hand object identification (for object Greend Sands?s can, Pocari Sweat?s can, and Biore) . The simulation result show that identification result which has best accuracy is when identifying between no object and object Green Sands?s can which has average value of correct percentage that reach 89% for each experiment and 94,6% for each experiment when identifying no object."
