Judul: The relationship between coffee consumption and blood  pressure in the outpatient at Bogor Tengah community health center
Abstrak: The objective of this research was to study the relationship pattern of coffee consumption with the incidence of hypertension in outpatient Bogor Tengah Community Health Center. The design of this study was Case Control in the ratio of cases and controls were 1:1 with a total of 160 subjects. The control subjects were defined who had blood pressure ≤120/≤80 mmHg, while the cases subjects had blood pressure ≥140/≥90 mmHg based on the doctor's diagnosis at least 1 month previously. Pattern coffee consumption data was collected through interviews using a questionnaire containing 15 questions. The habit of drinking coffee in the case group decreased after being diagnosed hypertension and showed a statistically significant difference (p<0,05). Coffee consumption more than 7 cups per week there is not statistically significant with the hypertension (OR=0,677; 95% CI: 0,333–1,378) (p>0,05).

Judul: Risk factors of hypertension of grade III and IV leadership training participants at Center of Management and Leadership Agricultural Training, Bogor
Abstrak: Prevalence of hypertension in Indonesia is quite high. The severe hypertension will cause serious disease such as coronary heart disease, stroke and kidney failure. The purpose of this study was to assess the risk factors of hypertension which include the inherent factors such a demographic factors and family history and modifiable risk factors such a lifestyle and health status. This study used a case-control study design. The respondents were the participants of grade III and IV leadership training at Center of Management and Leadership Agricultural Training, Bogor. The sample of this study were 96 participants consisting of 48 cases (hypertension) and 48 controls. Analysis of the data was bivariate and multivariate with linier regression. More than three quarters of respondents (80.2%) aged 40 years old and over, where the group of hypertension was 83.3% and group with no hypertension was 77.1%. More than three quarters of the respondents (78.1%) were male, where there is no different proportion between hypertension dan no hypertension group were 77.1% and 79.2%. In term of hypertension family history, the case group with family history of hypertension was 62.5%, more than the control group with family history of hypertension was only 41.7%. Life style, which include eating fatty and salty foods habits, exercise, and smoking habits were also studied. The study refeal that there is no significant different (p <0.05) between the cases and control group in life style. There was no significant (p< 0.05) between the cases and control group in health status which include the nutritional status (BMI) and estrogen contraceptive usage (specific for female respondents), except the presence of stress. The variables which significant (p<0.05) with hypertension were family history of hypertension and presence of stress.

Judul: Rakitan elektrode membran komposit polisulfon tersulfonasi-zeolit teraktivasi untuk aplikasi sel bahan bakar metanol langsung
Abstrak: Penelitian ini menyintesis dan mencirikan rakitan elektrode membran (MEA) dari komposit polisulfon tersulfonasi-zeolit teraktivasi (PSfs-Z). Sulfonasi telah berhasil dilakukan yang dibuktikan dengan nilai derajat sulfonasi sebesar 32.63% dan serapan pada bilangan gelombang 1740.15 cm-1 yang menyatakan bahwa ada gugus sulfonat yang tersubstitusi 1,2,4,- pada posisi orto-. Membran komposit diperoleh dengan menambahkan zeolit teraktivasi. Hasil yang optimum ditunjukkan oleh aktivasi dengan HCl 3 N. Keberhasilan pembuatan MEA terlihat dari morfologinya yang dicirikan menggunakan mikroskopi elektron payaran dengan terbentuknya lapisan katalis dan membran pada penampang lintang. Nilai konduktivitas proton dan beda potensial tertinggi yang diperoleh MEA PSfs-Z 3 N berturut-turut 17.27×10-3 S/cm dan 330 mV. Dengan demikian, dapat disimpulkan bahwa MEA dari komposit PSfs-zeolit teraktivasi dapat diaplikasikan untuk DMFC.
