Judul: Pengaruh Teh Putih Dibandingkan dengan Teh Hijau terhadap Status Oksidatif dan Profil Lipid Perokok
Abstrak: Smoking long-term and short-term has been known significantly increase oxidative damage. Smoking accelerates blood clotting which is one of the factors causing atherosclerosis which leads to heart disease. Triglyceride (TG), total cholesterol (TC), and Low Density Lipoprotein- Cholesterol (LDL-C) of smokers were higher than non-smokers. These negative effects has not able to reduced smoking activity. The datas of National Basic Health Research from Ministry of Health showed that the number of smokers and the number of cigarettes rised continually. Phytoteraphy with tea can be used to minimalized these negative effects. There are many types of tea that generally known in public is black tea, green tea and oolong tea. Nowdays white tea have been introduced to the public despite not popular as other types of tea. Research on the white tea was still limited, especially about the effect of white tea on oxidative stress and lipids profile in smokers. The main objective of this study was to determine the effect of white tea compared with green tea on smoker’s oxidative status and lipids profile. There were four specific aims: to determine nutritional status, the age started smoking, and cigarrette type of the subjects; to determine consumption, level of nutritional adequacy, and physical activity of subjects before and during the intervention; to analyze the effect of white tea compared with green tea on oxidative status of subject and; to analyze the effect of white tea compared with green tea on lipids profile of subjects. This study used paired sample clinical trials design with 9 subjects with inclusion criteri: male, age 30-45 year, medium smokers (11-21 cigarettes/day), had smoked at least for 6 months, and mild dyslipidemia. The Exclusion criteria were not taking tea, taking drugs that may affect lipids profile, drinking alcoholic beverages and supplements. Subjects were asked to drink tea in 2 period of times. Firstly, all subjects were asked to drink 3x200 ml white tea/day for 28 days. Secondly, treatment started after 14 days washout period, and they were asked to drink 3x200 ml of green tea/day for 28 days. Lipids profile and Total Antioxidant Capacity (TAC) were analyzed using blood serum subjects before and after the intervention in each period of white tea and green tea in an accredited clinical laboratory. Most subjects had overweight nutritional status (44.44 %), started smoking at 17 year-old (44.44 %) and all subjects smoked clove filtered cigarettes. There was no significant difference (p> 0.05) in nutrients intake, number of cigarettes smoked and the physical activity of subjects before and during the intervention. TAC subjects significantly increase 0.25 m mol/L (Δ) after intervention of white tea and 0.16 m mol/L (Δ) after intervention of green tea (p <0.05). The effect of white tea on increasing TAC significantly higher (p <0.05) than green tea (Δ=0.09 m mol/L). White tea and green tea have been observed to have positive impact on subject’s lipids profile. White tea intervention significantly decrease 35 mg/dl (Δ) TG and 41 mg/dl (Δ) LDL-C, while for green tea intervention can only reduced 34 mg/dl LDL-C significantly. Effect of white tea on TG and

Judul: Effect Intervention of Drink Consist of Green Coffee, Green Tea and Cinnamon on Blood Sugar and Lipid Profile Overweight/Obese Hypercholesterolemia men.
Abstrak: Penyakit Tidak Menular (PTM) merupakan penyebab kematian utama yang berhubungan dengan pola makan yang tidak sehat. Teh hijau (Camellia sinensis) merupakan, polifenol yang dapat menurunkan risiko penyakit kardiovaskular. Konsumsi teh hijau lebih dari dua gelas perhari secara signifikan menurunkan serum kolesterol total dan trigliserida. Kopi hijau diduga berefek terhadap penurunan berat badan. Kayu manis (Cinnamon) mengandung sinnamaldehid yang dapat menurunkan berat badan dan kolesterol. Penelitian ini bertujuan untuk menganalisis efek pemberian minuman kombinasi bubuk kopi hijau, teh hijau dan kayu manis (KTM) terhadap profil lipid dan gula darah pada subjek overweight/obesitas dan hiperkolesterolemia. Tujuan khusus penelitian ini antara lain: (1) menganalisis efek pemberian minuman KTM terhadap perubahan asupan dan tingkat kecukupan gizi (2) menganalisis efek pemberian minuman KTM terhadap perubahan profil lipid darah (kolesterol total, LDL, trigliserida dan HDL), (3) menganalisis efek pemberian minuman KTM terhadap perubahan kadar gula darah puasa subjek. Penelitian ini menggunakan desain penelitian pre-post experimental dan telah mendapatkan persetujuan etik dari Komisi Etik Penelitian IPB dengan No. 132/IT3.KEPMSM-IPB/SK/2018. Penelitian dilakukan selama delapan minggu dari bulan Maret-Mei 2019. Lokasi penelitian dilakukan di kampus Instititut Pertanian Bogor (IPB), Dramaga, Jawa Barat. Jumlah subjek pada penelitian ini adalah 14 orang. Kriteria inklusi penelitian adalah 1) staf IPB University; 2) jenis kelamin laki-laki berusia >25 tahun; 3) IMT ≥25,0 kg/m2; 4) kadar kolesterol total ≥200 mg/dl; 5) bersedia berpartisipasi dan menandatangani informed consent. Kriteria eksklusi penelitian ini adalah 1) berpartipasi penelitian lain; 2) menjalani terapi pengobatan; 3) menderita penyakit terkait sistem pencernaan; 4) alergi, sensitif dan atau tidak menyukai produk berbasis teh hijau, kopi hijau dan kayu manis; 5) mengonsumsi obat penurun kolesterol atau suplemen antioksidan. Perbandingan bahan yang digunakan antara kopi hijau, teh hijau dan kayu manis dengan perbandingan rasio 3:4:2. Intervensi minuman KTM selama delapan minggu menurunkan berat badan, IMT, persen lemak tubuh, kadar kolesterol total secara signifikan. Terdapat kecenderungan penurunan kadar kolesterol LDL dan trigliserida. Hasil menunjukkan terdapat perbedaan signifikan asupan rata-rata energi dan lemak sebelum dan setelah intervensi (P<0,05). Penelitian ini membuktikan bahwa pemberian intervensi minuman KTM pada subjek overweight/obesitas dan hiperkolesterolemia dapat menurunkan kolesterol total, berat badan, persen lemak tubuh tanpa mempengaruhi kadar gula darah subjek yang normal. Minuman KTM dapat dijadikan alternatif produk menurunkan kolesterol total, berat badan dan lemak tubuh pada subjek hiperkolesterolemia dan overweight/obes., Non-Communicable Diseases (NCD’s), a leading cause of death, is associated with unhealthy diet. Consumption of food containing bioactive components could prevent NCD’s. Green tea (Camellia sinensis) contains polyphenols that significantly reduces serum total cholesterol and triglycerides. Green coffee have an effect on weight loss. Cinnamon (Cinnamon) contains cinnamadehyde that have an effect on lower body weight and cholesterol. This study aims to analyze the effect of giving a combination drink of green coffee powder, green tea, and cinnamon (GGC) on lipid profiles and blood sugar in overweight/obese and hypercholesterolemic subjects. The specific objectives of this study : (1) analyzing the effect of giving GGC drinks on changes in intake and the level of nutritional adequacy, (2) analyzing the effect of giving GGC drinks on changes in blood lipid profiles (total cholesterol, LDL, triglycerides, and HDL), (3) analyzing the effect of

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.
