Judul: Analysis of Physical Environmental, Socio-Economic, and Food Consumption Patterns on Hypertension in West Java
Abstrak: Hipertensi di Jawa Barat menempati urutan kedua setelah Kalimantan Selatan dengan prevalensi 39,6%. Prevalensi hipertensi yang cukup tinggi dapat dipengaruhi oleh banyak faktor. Tujuan penelitian ini adalah menganalisis faktor lingkungan fisik, sosial-ekonomi dan pola konsumsi pangan terhadap hipertensi di Jawa Barat. Penelitian menggunakan data sekunder mencakup 26 kabupaten/kota di Provinsi Jawa Barat. Desain penelitian yang digunakan yaitu ecological study. Lokasi penelitian adalah Provinsi Jawa Barat. Proses pengolahan dan analisis data dilakukan pada bulan Agustus-September 2022. Hasil penelitian menunjukan bahwa peningkatan 10% pencapaian indikator lingkungan fisik berpengaruh signifikan terhadap hipertensi sebesar 5,84%. Peningkatan 10% pencapaian indikator sosial-ekonomi dapat berperan secara langsung meningkatkan 6,87% pencapaian indikator kondisi lingkungan fisik, meningkatkan 6,02% konsumsi air, menurunkan 5,61% konsumsi pangan (energi dan natrium), serta menurunkan 5,74% hipertensi. Secara tidak langsung, peningkatan kondisi sosial-ekonomi sebesar 10% akan meningkatkan hipertensi sebesar 6,52% sebagai akibat perubahan kondisi lingkungan fisik dan konsumsi pangan. Kondisi lingkungan fisik, sosial-ekonomi, dan konsumsi air maupun energi serta natrium berpengaruh sebesar 22,2% terhadap hipertensi di Jawa Barat, sedangkan sisanya dapat dijelaskan oleh variabel lain diluar penelitian. Nilai Q2 yang didapatkan dari model terbentuk dapat dikatakan cukup baik (0,605).

Judul: Faktor Risiko Hipertensi Pada Empat Kabupaten/Kota Dengan Prevalensi Hipertensi Tertinggi Di Jawa Dan Sumatera
Abstrak: Hypertension is a common public health problem that occur both of developed and developing countries. Increasing prevalence of hypertension independently associated with diet and lifestyle. Untreated hypertension leads to many degenerative diseases, including renal disease, congestive heart failure and peripheral vascular disease. Therefore the purpose of this study is to examine factors that can be protective and enhance hypertension prevalence, so that population can save their blood pressure (BP) by preventive and rehabilitative methodes. This study is a cross-sectional analysis in 5 104 subjects aged 18-97 y, consist of 2 491 males and 2 613 females. Data on Body Mass Index (BMI), BP, and other background characteristics of study partisipant were generated using the Riset Kesehatan Dasar (Riskesdas) 2007, at four demographics surveillance sites in Kuantan Singingi and Rokan Hilir (Riau Island), Wonogiri and Salatiga (Central Java). Hypertension was define as SBP≥140 mmHg or DBP≥90 mmHg, with adaptation of the recent JNC-7 definitions. Multiple logistic regression analyses were carried out to determine the odds of hypertension across the whole characteristic, while controlling for possible confounding. A high prevalence of hypertension was noted among four regions population in Kuantan Singingi (48.8%), Rokan Hilir (49.8%), Wonogiri (50.7%) and Salatiga (47.0%). The risk factor which can be reduce hypertension prevalence are ages 40-60 y (OR=0.229) and >60 y (OR=0.501), didn’t do middle physical activity (OR=0.814), didn’t do walking or ride bicycle (OR=0.744), underweight (OR=0.544) and overweight (OR=0.372). While the risk factor which can be enhance hypertension prevalence are education junior and senior high school (OR=1.292) and eating much salty foods (OR=1.258).

Judul: The Exploration of Discrete Logarithm over Finite Field GF(3m)
Abstrak: The security of many public~key algorithms is based on the problem of finding discrete logarithms. The generalized discrete logarithm problem is the following: given a finite cyclic group G of order n, a generator a of G, and an element fl E G, find the integer x, 0 ~ x ~ n - 1, such that 0: = fl. Algorithm for discrete logarithm problem focused on Menezes et al. (1997) that consist of exhaustive search algorithm, the baby-step giant-step algorithm, Pollard's rho algorithm, Pohlig-Hellman algorithm, and index-calculus algorithm. These algorithms are explorated to be used in discrete logarithm problem over finite field GF(3m ). The exploration also produces some algorithms, i.e. naif negative algorithm, baby-step mother-step algorithm, baby-step mother free-step algorithm, and baby-step free-step algorithm. All algorithms implemented using Maple 11. The Pohlig-Hellman and baby-step giant-step algorithms are efficient enough to be used in discrete logarithm problem over finite field GF(3m ) for m < 20.
