Judul: Konsumsi Minyak sawit Merah Meningkatkan Jumlah Sel Natural Killer dan Menurunkan Kadar Enzim Siklooksigenase 2 pada Limfosit Ibu Rumah Tangga di Kecamatan Dramaga Bogor.
Abstrak: Salah satu vitamin yang berperan penting dalam imunitas tubuh adalah vitamin A. Selain penting dalam mekanisme penglihatan, vitamin A juga dapat mencegah atau menurunkan resiko timbulnya berbagai penyakit degeneratif seperti kanker. Crude palm oil (CPO) yang berwarna merah sehingga sering disebut minyak sawit merah atau red palm oil tanpa melalui proses pemucatan merupakan sumber provitamin A dengan komponen utamanya α dan β-karoten yang memiliki aktivitas provitamin A (El-Hadad et al. 2011). β-karoten dikenal sebagai salah satu bahan alami pencegah kanker. ...dst

Judul: Penerimaan Konsumsi Minyak Sawit Mentah dan Pengaruhnya Terhadap Aktivitas Enzim Antioksidan Sel Darah Merah Responden di Kecamatan Dramaga Bogor
Abstrak: Crude palm oil (CPO) is red colored oil derived from palm fruit husk. CPO contains 500-700 pmm β-carotene, 600 ppm vitamin E, ubiquinone, squalene, and lutien which functioned as antioxidants. These antioxidants can modulate antioxidant enzymes such as superoxide dismutase and catalase to ward off free radicals. However, the use of this oil is still scarce as a source of antioxidant. The objectives of this research were to investigate the consumption acceptance of crude palm oil and its effect on antioxidant enzymes activity. Seventy eight respondents from low income families were selected to receive 140 ml CPO / week for 2 month. The distribution activities were monitored using questionnaires to determine consumer acceptance of the product. Blood from twenty two respondents, consisting of productive-aged women, was withdrawn before and after consumption and the erythrocyte was analyzed for activity of superoxide dismutase using nitro blue tetrazolium reduction assay and catalase spectrophotometrically. The results showed that product was accepted by 96 – 100 % respondents after two weeks until two months consumption. The erythrocyte SOD increased from 4.592 ± 1.336 U/mg protein to 4.767 ± 1.222 U/mg protein and catalase increased from 1018.911 ± 0.055 to 1219.607 ± 0.065 Unit/mg protein (mean ± SD) after consumption of approximately 3.771 ml CPO/person/day. From this research we can conclude that intervention with CPO for two months not only change and improve the knowledge of respondent about natural antioxidant, but also can increase the activity of antioxidant enzyme in human erythrocyte.

Judul: Modeling of inverted pendulum system with oblique trackand parameter characterizationon optimal tracking error problem
Abstrak: Inverted pendulum is an important device in education and research for control engineering. Many results of research are reached through study to pendulum system. The primary objective of this thesis is to characterize the inverted pendulum system with oblique trackon the optimal tracking error problem in terms of the system of parameters. We first derive the equations of motion for the pendulum system with flat track and the next endittothe system with oblique track.We then derive the analytical expressions of the optimal tracking error problem for both systems. It is shown that the expressions are completely determined by the pendulum’s parameters. Furtherm ore, its is shown that the lowest possible tracking error can be attained as long as the ratio between pendulum and motor masses is equal to a certain constant, regardless the material of the pendulum.
