Judul: Hubungan Status Gizi dan Tekanan Darah terhadap Kadar CReactive Protein Darah pada Subyek Dislipidemia.
Abstrak: The increase of body fat mass and blood pressure have been reported to have association with the increase of cardiovascular diseases risks, which mechanism is mediated through the increase of inflammation status caused by impaired blood lipids (dyslipidemia). The objective of this study was to analyze association between nutritional status (Body Mass Index (BMI), waist circumference, waist-hip ratio, and body fat mass) and blood pressure with inflammation state which was assessed by blood C-reactive protein level in dyslipidemic subjects in Bogor. The study design was cross sectional survey involving 81 dyslipidemic subjects. The study showed that there were significant correlations between BMI, waist-hip ratio and body fat mass, diastolic blood pressure with blood CRP level. In conclusion, the higher percentage of over nutritional status, body fat mass, and diastolic blood pressure, the higher the inflammation status.

Judul: Hubungan Asupan Serat dengan Status Gizi dan Profil Lipid Darah pada Orang Dewasa Dislipidemia
Abstrak: Dyslipidemia has been reported to be one of the trigger for degeneratif diseases. Dyslipidemia is metabolism disorder of one or more lipid component such as cholesterol total, triglyceride, HDL (High Density Lipoprotein) cholesterol, and LDL (Low Density Lipoprotein) cholesterol. The objective of this study was to analyze the association of fiber consumption with nutritional status and blood lipid profile in dyslipidemic adults. The design study was cross sectional survey involving 79 subjects. The results showed that there were significant correlations (p<0.05) between energy intake with HDL cholesterol and total cholesterol, fat intake with BMI (Body Mass Index), and BMI with cholesterol LDL and total cholesterol (p<0.05). There was no significant correlation (p>0.05) between consumption of fiber with nutritional status and blood lipid profile. In conclusion, most of the dyslipidemia subjects were obese. On the dyslipidemia subjects, consumption of fibers did not relate with nutritional status and blood lipid profile. Dyslipidemia subjects should keep their intake of energy and fat in recommended ranges in order not to be obese and keep the BMI in normal range to avoid abnormalities of blood lipid profile.

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.
