Abstrak: Studies have shown a strong association between cardiovascular disease and high levels of plasma cholesterol in himans and other species, including swine. Since there is anatomical and physiological similarity between pid and humans, information on factors affecting plasma cholesterol levels in human may reflect similar association in pig. A review of literatures on human experiments indicates that fiber content of food can decrease plasma cholesterol. Thirty-six male Landrace pigs with live weight between 8 and 10 kg were used in this study to determine the effect of seaweed and rice hulls as fiber sources on carcas fat and meat cholesterol.

Judul: The Relationship between Plant Sterols Intake and Total Blood Cholesterol Level in Bogor Rural Area
Abstrak: Coronary heart disease (CHD) is the most common cause of death in Indonesia. Lowering cholesterol level is currently one of the most efficient and effective way to prevent or reduce the risk of CHD and other cardiovascular disease (CVDs). One of the compounds that have the cholesterol-lowering ability is plant sterols. To further research about plant sterol efficacy for health and its application as functional food ingredient in Indonesia, an up-to-date data about plant sterols dietary intake is required. The study was conducted with a cross sectional design to estimates the plant sterols (PS) intake and its relationship with total blood cholesterol level in Bogor rural area. Data of plant sterols level in food obtained by secondary data and calculation of recipe. Based on the results, the level of plant sterols intake of total respondent was averagely 223.80 mg/day with no statistical difference between male and female intake (t(98) = - .036, p > 0.05). The plant sterols intake in all respondents was mostly contributed by cereals and cereals product (37.46%), followed by legumes and legume products (24.41%). According to Pearson correlation test, there was no association between daily intake of plant sterols and total blood cholesterol (P > 0.05), which mean that the intake level not yet have visible effect in lowering or raising total blood cholesterol levels in respondents with health nutritional status, but presumed maintain normal blood cholesterol levels in respondents.

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.
