ABSTRAK<br />Penelitian dilakukan untuk mengetahui pengaruh pemberian air<br />terhadap tiga aksesi sambiloto untuk meningkatkan produktivitas dan mutu<br />simplisia. Dilaksanakan di rumah kaca Balittro (Balai Penelitian Tanaman<br />Obat dan Aromatik), Bogor, dari bulan Juni sampai Desember 2006.<br />Rancangan yang digunakan adalah petak terbagi, dengan ulangan tiga<br />kali. Petak utama adalah aksesi sambiloto (3 nomor) yaitu Cmg-1, Cmg 2,<br />dan Blali-1, anak petak adalah pemberian air (5 perlakuan) yaitu 3, 4, 5, 6,<br />dan 7 mm/hari. Hasil penelitian menunjukkan bahwa tidak ada interaksi<br />antara aksesi sambiloto dan tingkat pemberian air terhadap pertumbuhan<br />tanaman (tinggi tanaman, jumlah cabang dan luas daun), kecuali pada<br />produksi berat segar 2 bulan setelah tanam (BST) dan produksi berat<br />kering pada 4 BST. Perlakuan Cmg-2 dikombinasi dengan pemberian air 5<br />mm/hari menghasilkan berat segar dan kering tertinggi. Perlakuan<br />pemberian air 3-7 mm/hari/tanaman dapat menghasilkan produksi dan<br />mutu simplisia yang dapat memenuhi standar Materia Medika Indonesia<br />(MMI) berdasar kadar air, kadar abu, dan kadar sarinya. Dengan demikian<br />kebutuhan air sambiloto setara dengan palawija atau sayur-sayuran. Mutu<br />Blali-1 dan pada perlakuan pemberian air 3 mm/hari menunjukkan kadar<br />sari larut alkohol tertinggi (22,28%) dan Cmg-2 pada perlakuan pemberian<br />air 4 mm/hari menunjukkan kadar sari larut air paling tinggi (28,14%) dan<br />kadar andrografolid simplisia 1,78%.<br />Kata kunci : Sambiloto, Andrographis paniculata Nees, tingkat<br />pemberian air, produksi, mutu simplisia<br />ABSTRACT<br />The effects of water treatment on some numbers of<br />accessions on the quality and production of the symplicia<br />of sambiloto, the king of bitter (Andrographis paniculata<br />Nees )<br />The experiment was carried out to study the effect of water<br />treatment three accession of sambiloto, the king of bitter, to increase its<br />productivity and symplicia. The experiment was conducted in the green<br />house of the Indonesian Medicinal and Aromatic Crop Research Institute<br />(IMACRI), Bogor, from June to December 2006. The experiment<br />arranged in split plot design with three replications, The main factor was<br />three accession number of sambiloto i.e. Cmg-1, Cmg-2, and Blali-1,<br />whereas the sub factor was water treatments i.e. 3 mm, 4 mm, 5 mm, 6<br />mm, and 7 mm/day. The results showed that there was no interaction<br />between the numbers of accessions and water treatment on the plant<br />growth except for fresh weight production at 2 Month After Planting<br />(MAP) and dry weight production at 4 MAP. Cmg-2 treatment combined<br />with water treatment (5 mm/day) produced the highest fresh and dry<br />weight. Water treatment of 3 - 7 mm/day produce the yield and quality that<br />meet standard of the Materia Medika Indonesia (the material medical of<br />Indonesia) based on the water, ash, and gist contents. Therefore, water<br />necessity of sambiloto is evenly balanced with secondary crops or<br />vegetables. The quality of Blali-1 on the water treatment of 3 mm/day<br />indicated the highest dissolved gist of alcohol (22.28%) meanwhile the<br />Cmg-2 on the water treatment of 4 mm/day showed the highest dissolved<br />gist of water (28.14%) and andrographolid content of symplicia is 1.78%.<br />Key words : King of bitter, Andrographis paniculata Nees, water<br />treatment, yield, quality of symplicia
