The study applied a cross sectional design to 246 senior high school students in Bogor. The subject aged 16-17 years old were selected purposively. Milk and calsium intake was derived from the food intake data collected by applying a semi-FFQ method for a week. Bone density (stiffness index) was measured by densitometer of achilles insight. The results of the study showed that the mean intake of milk was 170.7±136.3 ml/day with average frequency 6 times/week, and mean intake of calcium was 250.0±212.6 mg/day with contribution of milk was 44.0%.

Susu kerbau merupakan salah satu sumber bakteri asam laktat (BAL) yang berpotensi sebagai kultur untuk starter maupun probiotik. Penelitian ini bertujuan untuk mengisolasi dan mengidentifikasi BAL asal susu kerbau sungai Sumatera Utara, serta menguji ketahanannya pada pH rendah. Bakteri asam laktat diisolasi dan ditumbuhkan pada medium De Man Rogosa Sharpe Agar (MRSA). Isolasi dilakukan sampai diperoleh kultur murni. Identifikasi BAL dengan pengujian karakteristik morfologi, fisiologi dan biokimia. Karakteristik morfologi dilakukan dengan pewarnaan Gram dan melihat bentuk sel. Karakteristik fisiologi dilakukan dengan uji ketahanan pada pH 4,5 dan suhu 45 o C. Karakteristik biokimia dilakukan dengan uji produksi CO2, NH3 dan dekstran. Pengujian sifat probiotik dilakukan dengan menguji ketahanan isolat BAL pada pH rendah. Pengujian dengan kit API tes CHL 50 untuk mengetahui jenis spesies dari sepuluh BAL terpilih. Hasil identifikasi diperoleh 41 isolat BAL, yang secara umum memiliki karakterisitik Gram positif, katalase negatif, berbentuk batang dan bulat. Pengujian ketahanan BAL pada pH rendah (pH 2) menunjukkan penurunan jumlah populasi sebanyak 1,24±0,68 log cfu/ml. Isolat terbaik dari pengujian ketahanan pada pH rendah adalah isolat L12, L16, L17, L19, L20, M10, P8, S3, S19 dan S20. Hasil pengujian dengan API test CHL 50 pada sepuluh isolat terpilih tersebut menunjukkan ada empat spesies BAL dari susu kerbau sungai Sumatera Utara, yaitu Lactobacillus plantarum, L. brevis, L. pentosus dan Lactococus lactis.

ABSTRAKHiperglikemi kronis pada penderita diabetes melitus tipe 2 meningkatkan terbentuknya radikal bebas yang disebabkan peningkatan peroksidasi asam lemak, yang akan mengarah pada komplikasi yang bersifat kronis. Peningkatan terbentuknya radikal bebas yang tidak diimbangi dengan peningkatan asupan antioksidan akan menimbulkan stres oksidatif. Penelitian dilakukan untuk menganalisis efek pemberian produk galohgor berupa cookies dan minuman serbuk terhadap status antioksidan dan penurunan penanda stres oksidatif pada penderita DM tipe 2. Sebanyak 18 subjek penderita DM tipe 2 dibagi menjadi 2 kelompok, yaitu kelompok intervensi (n=9) diberikan cookies dan minuman serbuk galohgor dan kelompok kontrol (n=9) diberi cookies dan minuman serbukyang tidak mengandung galohgor selama 38 hari. Penelitian dilaksanakan di wilayah Lingkar kampus Institut Pertanian Bogor. Aktivitas antioksidan plasma dianalisis dengan metode 2,2-diphenyl-1-pycrilhydrazyl (DPPH), sedangkan stres oksidatif dinilai dengan mengukur kadar Malondialdehyde (MDA) plasma. Data dianalisis menggunakan independent t test, paired t test dan ANCOVA. Hasil penelitian menunjukkan rata-rata selisih aktivitas antioksidan setelah dikoreksi pada kelompok intervensi dibandingkan dengan kelompok kontrol masingmasing adalah +4.07% dan+1.78% (p>0,05), sedangkan selisih MDA plasma kelompok intervensi dibandingkan dengan kelompok kontrol sebagai berikut -0,56 nmol/ml dan+7,05 nmol/ml (p<0,05). Produk galohgor berupa cookies dan minuman serbuk galohgor signifikan menurunkan stres oksidatif pada penderita DM tipe 2. Kata kunci : Diabetes, DPPH, galohgor, MDA ABSTRACT Chronic hyperglycemia in type 2 diabetes mellitus leads the formation of free radicals due to increased lipid peroxidation in the body, which will be followed by chronic complication. The increasing of free radicals formation without compensation by antioxidant enhancement will produce oxidative stress. The aim of this study was to analyze the effect of feeding galohgor's product in the form of cookies and instan drinks to antioxidant activityand oxidative stress marker in plasma type 2 diabetes mellitus. Total 18 subjects were divided into 2 groups. All participants was given cookies and powdered drinkscontained galohgor (for intervention group, n=9) and without galohgor (as control group, n=9 07% and +1,78 % (p>0,05),56 nmol/ml and +7,05 nmol/ml(p<0,05). In conclusion, Galohgorproductsin the form of cookies and powdered drinks significantly decreased oxidative stress in type 2 diabetes mellitus.
