Aktivitas Antioksidan Minuman Fungsional dari Irisan Buah Kering Mahkota Dewa
Buah mahkota dewa (Phaleria macrocarpa (Scheff) Boerl) mengandung zat-zat aktif yang mempunyai aktivitas antioksidan. Penelitian ini bertujuan untuk mengetahui pengaruh metode pengolahan dan jenis pemanis terhadap kadar dan aktivitas antioksidan minuman mahkota dewa. Kombinasi perlakuan terbaik yang memiliki kadar dan aktivitasantioksidan paling tinggi adalah kombinasi perlakuan perendaman dan jenis pemanis madu yang ditunjukkan dengannilai total fenol sebesar 11,01 ppm, penghambatan peroksida sebesar 83,02 %, dan penghambatan malonaldehida(MDA) sebesar 67,54 %. Kemampuan terhadap penghambatan pembentukan peroksida dan MDA tersebut lebih besardari α tokoferol
Beberapa Faktor Risiko Yang Berpengaruh Terhadap Kejadian Penyakit Demam Berdarah Dengue (Dbd) Di Kabupaten Banyumas
Dengue Hemorrhagic Fever (DHF) is a communicable disease which caused by a dengue virus and spread by Aedes sp. Mosquito especially Aedes aegypti. DHF disease marked with 2 - 7 days fever, sometimes bifasik, bleeding tendency with at least one matter: youniquet test positive, petekie, ekimosis or porpura, bleeding from mukosa, gastrointestinal line, injection spot or other spot, hematemesis ormelena. The aim ofresearch is to analyze risk factor that influenes incident DHF disease. While the reason of this research is giving information what is the dominant risk factor were to incident DHF disease and kind of dengue virus infection at Bayumas. Case control design was applied in this study. From bivariate analysis result know that become at risk faktor is: aged, sex, plants around hause and raise bird While at regresion logistics test can be noted that proved risk factor only 4 factors, that is: aged, sex, raise bird and not using anti mosquito repelent. Based from this study, we suggest to do monitoring and entomology cases, inter program and sectoral meeting, movement active role and changing people behavior
Efek Pemberian Gula Kelapa yang Diperkaya Minyak Sawit Merah terhadap Peningkatan Berat Badan dan Kadar Retinol Serum Tikus Defisien Vitamin A (Effect Of The Feeding Of Brown Sugar Enriched With Red Palm Oil On Body Weight Gain And Serum Retinol Levels
Vitamin A deficiency (VAD) is an important cause of blindness and premature death. Vitamin A also plays an important role on growth and immune function. Red palm oil is the richest naturally occurring source of β-carotene, a carotenoid that the human body can convert into USAble vitamin A (retinol). This research was to evaluate the effect of feeding red palm oil enriched brown sugar on improving body weight and serum retinol level of vitamin A depletion Sprague-Dawley rats. Twenty four of six weeks old-male Sprague Dawley rats were used. After 2 weeks of adaptation period, rats were given vitamin A deficient diet (modified AIN-93M) for 10 weeks, and then divided into 3 groups and received for 2 weeks the different treatment as repletion period: 1) RPO group which received red palm oil enriched brown sugar (1.5 mL/d), 2) CPO group which received crude palm oil enriched brown sugar (1.5 mL/d) and 3) and RE group which received retinyl palmitate (0.6 mL/d) . Each treatment contains approximately 40 µg beta carotene/day. Intervention by feeding brown sugar enriched with RPO and CPO for 2 weeks can increase the body weight of rats by 3.54 percent and 5.23 percent, respectively, which is markedly better than the group that was given retynil palmitat (9.38%) (p<0.05). However, an increase in serum retinol concentrations in all group showed no significant differences (p>0.05). Consumption of brown sugar enriched with RPO or CPO enhances body weight and serum retinol concentration of vitamin A deficient rats
Pengaruh Pemberian Kopi yang Diformulasikan dengan Antioksidan dan Gula Kelapa terhadap Tekanan Darah, MDA, dan SOD Serum Tikus Obesitas
Pengembangan kopi mix tinggi antioksidan dengan pemanis gula kelapa adalah salah satu alternatif untuk mensuplai antioksidan pada individu obese guna menekan stress oksidatif. Minyak sawit merah (MSM) yang kaya antioksidan ditambahkan dalam proses pembuatannya. Tujuan penelitian untuk mengetahui pengaruh pemberian minuman kopi mix gula kelapa terhadap tekanan darah, kadar SOD, dan MDA tikus obesitas. Penelitian eksperimental menggunakan 18 ekor tikus yang diinduksi menjadi obese dengan diet tinggi lemak (indeks Lee>0,3). Dibagi 3 kelompok (n=6), masing-masing mendapatkan perlakuan: (1) kopi mix gula tebu tanpa MSM = 0,45 g/200 g BB/ hari (P1); (2) kopi mix gula kelapa dengan MSM= 0,45 g/200 g BB/hari (P2); dan (3) kopi mix gula kelapa dengan MSM= 0,90 g/200 g BB/hari (P3). Intervensi dilakukan selama 2 minggu. Pengamatan terhadap Perubahan berat badan, tekanan darah, kadar SOD, dan MDA serum (pre-post). Hasil penelitian menunjukkan bahwa pemberian kopi mix gula kelapa dengan MSM pada tikus obese (P2 dan P3) secara nyata menurunkan tekanan darah (26,9% dan 40,6%), dan kadar MDA serum (35,3% dan 61,8%), serta menaikkan SOD serum (28,79% dan 53,66%), sebaliknya pada kelompok kopi mix gula tebu tanpa MSM terjadi peningkatan tekanan darah (2,9%) dan kadar MDA (1,9%), serta menurunkan kadar SOD (16,6%). Peningkatan berat badan pada kelompok kopi mix gula tebu non MSM secara nyata lebih tinggi (P1=7,8%), dibandingkan kelompok kopi gula kelapa dengan MSM (P2=6,7%; P3=4,4%). Kopi mix tinggi antioksidan dengan pemanis gula kelapa berpotensi sebagai pangan alternatif untuk menekan stress oksidatif pada tikus obesitas
Pengaruh Spesies Zingiberaceae (Jahe, Temulawak, Kunyit, Dan Kunyit Putih) Dan Keetbalan Isiran Sebelum Pengeringan Terhadap Kadar Dan Aktivitas Antioksidan Ekstrak Aseton Yang Dihasilkan
This research was aimed to determine the influence ofzingiberaceae species and the influence ofslice thickness before drying process by using cabinet dryer to the antioxidant content (total phenolics and curcumin) and antioxidant activity (absorbance of peroxide and malonaldehide ). The results of the research showed that total phenolics of turmeric extract (216.57 ppm) and temulawak (190.41 ppm) > ginger (127,97 ppm) > white turmeric extract (31,13 ppm), where as curcumin content of turmeric (55,93 ppm) and temulawak extract (48,95 ppm) > white turmeric (6,51 ppm) and ginger extract (4,67 ppm). The antioxidant activity that is indicated peroxide and malonaldehide forming from 1 inoleic acid which is supplemented to temulawak extract, turmeric, and ginger extract > white turmeric extract. Turmeric, temulawak, and ginger extract had the antioxidant activity higher than tocopherol, where as white turmeric had lower antioxidant activity than a tocopherol. The slicing sample with slice size of 4 mm before drying process with cabinet dryer had rate and antioxidant activity better than that of 2 mm. The total phenolics of zingiberaceae extract with slice size of 4 mm (161,86 ppm) > 2 mm (121,18 ppm), and the curcumin content of zingiberaceae extract with slice of 4 mm (34,58 ppm) > 2 mm (23,45 ppm). The slice of 4 mm had a relatff higher value than the slice of 2 mm to the antioxidant activity zingiberaceae extract that is indicated peroxide and malonaldehide formation
