dc.description.abstractTumbuhan rotan (Calamus caesius Blume.) merupakan palem berduri yang memanjat termasuk dalam suku arecaceae, memiliki batang beruas yang bagian tengahnya tidak kosong dan berisi jaringan pembuluh. Rotan muda dimanfaatkan sebagai bahan makanan khas masyarakat Mandailing di Tapanuli Selatan yang biasa disebut pakkat. Penelitian ini bertujuan untuk mengetahui apakah terdapat kalsium, kalium dan magnesium dan untuk mengetahui kadar serta perbedaan kadar kalsium, kalium dan magnesium pada pakkat segar, pakkat bakar, dan pakkat rebus. Sebelum dilakukan analisis terlebih dahulu sampel didestruksi kering, kemudian analisis kuantitatif kalsium, kalium dan magnesium dilakukan dengan menggunakan metode Spektrofotometri Serapan Atom (SSA) yaitu kalsium pada panjang gelombang 422,7 nm, kalium pada panjang gelombang 766,5 nm dan magnesium pada panjang gelombang 285,2 nm dengan nyala udara-asetilen. Keuntungan dari metode ini yaitu mempunyai kepekaan yang tinggi (batas deteksi kurang dari 1 ppm) dan pelaksanaannya relatif sederhana. Hasil penelitian menunjukkan kadar kalsium pada pakkat segar sebesar (52,1162 ± 0,4210) mg/100 g, pakkat bakar sebesar (47,1917 ± 0,6996) mg/100 g dan pakkat rebus sebesar (40,3622 ± 0,8665) mg/100 g. Kadar kalium pada pakkat segar sebesar (108,2954 ± 0,4621) mg/100 g, pakkat bakar sebesar (82,3384 ± 0,6472) mg/100 g dan pakkat rebus sebesar (79,6948 ± 0,6818) mg/100 g. Kadar magnesium pada pakkat segar sebesar (49,3565 ± 0,5867) mg/100 g, pakkat bakar sebesar (40,8433 ± 0,6871) mg/100 g dan pakkat rebus sebesar (32,8071 ± 0,8274) mg/100 g. Hasil penelitian menunjukkan bahwa kadar kadar kalsium, kalium dan magnesium pada pakkat segar lebih tinggi daripada kadar pada pakkat bakar dan pakkat rebus.en_US
dc.description.abstractPlant rattan (Calamus caesius Blume.) Is a spiny climbing palm included in Arecaceae tribe, has a segmented rod which the middle is not empty and contains a network of vessels. Young rattan used as a food ingredient typical Mandailing community in South Tapanuli commonly called pakkat. This study aims to determine whether there are calcium, potassium and magnesium and to determine levels as well as different levels of calcium, potassium and magnesium in fresh pakkat, pakkat grilled, and pakkat boiled. Before analysis sample have destructed using dry destruction method, then the quantitative analysis of calcium, potassium and magnesium were calculated using atomic absorption spectrophotometry (AAS) is calcium at a wavelength of 422.7 nm, potassium at a wavelength of 766.5 nm and magnesium at a wavelength 285.2 nm with air-acetylene flame. Advantages of this method is to have a high sensitivity (limit of detection of less than 1 ppm) and the implementation is relatively simple. The results showed levels of calsium on fresh pakkat (52.1162 ± 0.4210) mg/100 g, pakkat grilled for (47.1917 ± 0.6996) mg/100 g and boiled pakkat by (40.3622 ± 0.8665) mg/100 g. Potassium levels in fresh pakkat of (108.2954 ± 0.4621) mg/100 g, pakkat grilled for (82.3384 ± 0.6472) mg/100 g and boiled pakkat by (79.6948 ± 0.6818) mg/100 g. Levels of magnesium in fresh pakkat (49.3565 ± 0.5867) mg/100 g, pakkat grilled for (40.8433 ± 0.6871) mg/100 g and boiled pakkat by (32.8071 ± 0.8274) mg/100 g. The results showed that the concentration levels of calcium, potassium and magnesium in fresh pakkat higher than levels at pakkat pakkat grilled and boiled.en_US
