Abstract

Tanaman soba (Fagopyrum esculentum) berasal dari wilayah subtropis, berpotensi sebagai pangan fungsional karena mengandung senyawa flavonoid antioksidan yaitu rutin. Kadar rutin sangat dipengaruhi oleh lingkungan. Penelitian ini bertujuan untuk mengetahui potensi tanaman soba sebagai sumber bahan pangan fungsional. Penelitian dilaksanakan di Kebun Pembibitan, desa Kopo (600 meter dari permukaan laut) Kabupaten Bogor, Jawa Barat, dari bulan Mei sampai Juli 2012. Metode yang digunakan adalah rancangan petak tersarang dalam rancangan acak kelompok dua faktor dengan tiga ulangan. Faktor pertama adalah naungan terdiri dari dua taraf, yaitu: tanpa naungan, dengan naungan paranet 55 persen, dan faktor kedua adalah populasi terdiri dari dua taraf, yaitu: 200 tanaman/m2, 50 tanaman/m2. Hasil penelitian menunjukkan produksi biji terbanyak pada kombinasi perlakuan tanpa naungan populasi 200 tanaman/m2 (N0P1) sebesar 764,3 g/m2 atau 7,643 ton/hektar dan terendah pada perlakuan dengan naungan paranet 55 persen populasi 50 tanaman/m2 (N1P2) sebesar 146,0 g/m2 atau 1,46 ton/hektar. Kadar rutin tertinggi diperoleh pada perlakuan tanpa naungan sebesar 0,398 mg/g biji. Produktivitas kadarrutin biji soba sebesar 304,19 mg/m2. atau 3,04 kg/hektar.Buckwheat (Fagopyrum esculentum), originated from subtropical regions, has the potential as a functional food because it contains flavonoid, called rutin. Rutin concentration is greatly influenced by the environment. The objective of this study is to determine the potential of the buckwheat plant as a functional food. The research is conducted in the nursery garden of Kopo village (600 m asl), Bogor District, West Java, from May to July 2012. The method used is the nested plot design in a randomized complete block design with two factors and three replications. The first factor is two levels of shading namely without shading and with shading of 55 percent paranet. The second factor is two crop densities namely 200 plants/m2 and 50 plants/m2. The research results show that the highest grain production (764.3 g/m2 or 7.643 tons/ha) is in the combination treatment of NOP1 and the lowest one (146.0 g/m2 or 1.46 tons/ha) is in N1P2 treatment. The highest rutin concentration is obtained on the treatment without shade at 0.398 mg/g groats. The productivity of rutin concentration of buckwheat groats is 3.04 kg/ha.

Abstract

Torbangun (Coleus amboinicus Lour) is a tropical plant from the Lamiaceae family. Torbangun leaves have a distinct aroma. Torbangun leaves have been traditionally used as a medicinal plant in North Sumatra, Indonesia. Bataknese lactating women in North Sumatra consumed torbangun leaves after giving birth with beliefs that it could increase their breast milk production (lactagogue), and that the leaves can function as anti-fungal and/or anti-bacterial, analgesic, to reduce blood cholesterol, and clean the human uterus. However, scientific evidence on this traditional herb is limited. This research was conducted to: (1) determine the leaf N, P, K, Ca and Fe in different position along the plant and the leaf age as to diagnose the secondary metabolites content of torbangun leaves, and (2) determine the relationship between N, P, K, Ca and Fe leaf concentrations with their metabolite production. The results of the study showed that: (1) the best leaf position and age to determine of the need of N, P, K, Ca and Fe nutrients are on the 3rd leaf position of 5 months-old plant (2) There was a positive correlation between leaf K concentrations with shoot dry weight, Ca with PAL activity, and Fe with total saponins on the 3rd leaf position of 5 months-old plant.Keywords: Coleus amboinicus Lour, torbangun, nutrient, correlation test, secondary metabolites.
