Judul: Formulasi Jamu Baru Antikolesterol Melalui Studi Bioinformatika Pangkalan Data Jamu dengan Ikan Zebra sebagai Hewan Model
Abstrak: Jamu formulation is based on pharmacological activity of the constituents. New jamu formula consisting of three supporting plants (analgesic, antibacterial, and antiinflammatory) and the main plant becoming efficacy target (anticholesterol). This new jamu was formulated using PLS (partial least square) with R-Gui software version 2.15.2 generated formula consisting of a mixture of Merremia mammosa tubers, leaves of Guazuma ulmifolia, Orthosiphon stamineus, and Murraya paniculata as the main plant. The formula was tested on zebrafish. The tested jamu formula were jamu formula 1 consisting of a mixture of the four plants with main plant as the most component and formula 2 with the main plant as single component. The total cholesterol average of zebrafish under normal condition was 220 mg/dL (p>0.05), while on the hypercholesterolemia condition was 272 mg/dL (p>0.05). After giving the extract for 7 days, formula 2 lowered total cholesterol greater than that of the formula 1; however, those values were not significantly different at the alpha value (p>0.05).

Judul: Pendekatan Bioinformatika Formulasi Jamu Baru Berkhasiat Antidiabetes dengan Ikan Zebra (Danio rerio) sebagai Hewan Model
Abstrak: Jamu composition was formulated without any provision like Traditional Chinese Medicine. Recent studies showed regularity pattern through statistical database. Jamu formulations in this study were made using Design Expert and its efficacy predicted using models partial least square discriminant analysis (PLSDA), coefficient PLSDA multiways, and Support Vector Machine. The prediction indicated that 4 plants used were sembung, pare, ginger, and bratawali. The efficacy was verified using zebrafish (D. rerio) as an animal test. Hyperglycemia in the fish was induced by soaking them in alloxan 0.1% for 10 min, glucose 1% for 10 min, and distilled water for 60 min in sequence. One-way t test showed that the increasing blood sugar levels was not significant (p>0.05). These results confirm that the induction process have not been successful to increase the average blood sugar levels. Application of jamu into the fish was done for 3 days after the induction. Statistical observation for all compositions of jamu showed that group 1 has the greatest decline difference.

Judul: Pemanenan Energi Listrik dari Kincir Angin Vertikal
Abstrak: Usaha pemanenan energi angin di Indonesia masih sedikit. Sampai Tahun 2016 hanya 3.54 MW alat pemanenan energi angin yang sudah terpasang. Kendala utamanya ialah dibutuhkan investasi yang besar untuk membuatnya. Pembuatan kincir angin dengan ukuran yang lebih kecil dengan bahan yang dapat dibeli di pasar lokal menjadi solusi agar pembuatan kincir angin lebih ekonomis. Pembuatan kincir vertikal tipe Savonius dapat menjadi solusinya. Kincir vertikal Savonius dapat beroperasi pada kecepatan < 3 m/s dan ketinggian < 50 m. Kincir angin ini terdiri dari tiga sistem, yaitu generator, rotor kincir dan transmisi pulley-belt. Generator dibuat dari modifikasi motor AC dan magnet neodymium. Rotor kincir dibuat dari pipa PVC 4”, pipa alumunium ¾”, dan papan polikarbonat. Transmisi pulley-belt dibuat dari plastik dan karet. Kincir ini membutuhkan gaya minimal 3 N untuk dapat berputar atau torsi minimalnya 0.75 Nm. Kecepatan angin yang dibutuhkan untuk merotasikannya sebesar 1.9 m/s. Daya maksimal yang dapat dihasilkan ialah 5.76 watt berupa tegangan sebesar 36 volt dan arus 160 mA.
