ADAPTASI EMPAT NOMOR HARAPAN MENTHA (Mentha arvensis L.) DI KP CICURUG

Abstract


Mint (Mentha arvensis L.) is one of the subtropic annual herbs as a source  of cormint and menthol oil. This oils have been widely used as raw material in pharmaceutical, beverage, food and aromatherapy industry. To meet the market demand, Indonesia is still importing cormint oil of 82,2 ton per year and menthol  oil 684,1 ton per year. Since this plants has been promising to cultivate, Balittro has devel­ oped four promising varieties of mint.1bose varieties are Mear 0010, Mear 0011, Mear 0012 dan Mear 0013. This study was aimed to determine the adaptation of four varieties of mint. The research was conducted at Cicurug Research Station at 550 m above sea level. The experimental design used was randomized complete block design that was arranged factorially with six replications. The parameters observed were the growth, herbs production, oil content, and the total amount of menthol. Results showed that the highest plants was indicated by Mear 0011 (66.56 cm) and the shortest was seen on Mear 0013 (43.05 cm), the largest diameter and the highest number of branches were also shown by Mear 0011. The longest node was the Mear 0010 (4.28 cm) and the shortest node was the Mear 0013. The longest Stolon was Mear 0010 (133.30 cm), and the largest Stolon was Mear 0011 (7.94), the number of leaves and the longest internode were also owned by Mear 0011 in the amount of 892.70 and 4.42 cm. Related to the production of herbs, fresh weight and dry weight, Mear 0011 yielded the heaviest fresh weight (113.30 g/plant), and the heaviest dry weight (35.83 g/plant). However, the production of oil was only 64.5 kg/Ha/year. This was lower that the oil production of Mear 0012 (79,5 kg/Ha/year). The higher levels of menthol content was also found on Mear 0011 (68.88%), but the oil level was not significantlly different from three other mint. This research showed that the quality of Mentha oil derived from M. arvensis (cornmint oil) meet the quality standards required by EOA especially to Mear 0010, 0011 and 0012.

Abstrak

Mentha (Mentha arvensis L.) merupakan herba tahunan dari daerah subtropik, banyak digunakan sebagai bahan baku dalam industri farmasi, makanan, minuman, dan aromaterapi. Indonesia masih impor minyak cormint 82,2 ton/tahun dan menthol 684,1 ton/tahun, padahal tanaman ini potensial untuk dikembangkan. Balittro memiliki empat nomor harapan M. arvensis yang diuji adaptasikan di beberapa ketinggian tempat.
Penelitian ini ditujukan untuk mengetahui daya adaptasi empat nomor harapan mentha (Mear 0010, 0011, 0012, 0013) terhadap pertumbuhan, produksi terna dan minyak, kadar minyak dan kadar total menthol. Penelitian dilakukan di KP Cicurug (550 m dpl). Pengujian menggunakan Rancangan Acak Kelompok enam ulangan, jarak tanam 60x40 cm dan jumlah 100 tanaman/petak. Pengamatan dilakukan terhadap parameter
pertumbuhan, produksi terna, produksi minyak, kadar minyak, dan kadar total menthol. Hasil menunjukkan tanaman tertinggi pada Mear 0011 (66,56 cm) dan terpendek Mear 0013 (43,05 cm). Diameter batang terbesar (0,47 cm) dan cabang terbanyak (25,70) pada Mear 0011. Ruas terpanjang pada Mear 0010 (4,28
cm) dan terpendek pada Mear 0013. Stolon terpanjang pada Mear 0010 (133,30 cm), jumlah stolon terbanyak pada Mear 0011 (7,94), jumlah daun terbanyak dan terpanjang Mear 0011 (892,70 dan 4,42 cm). Rata-rata bobot terna segar dan kering angin pada Mear 0011 (113,30 dan 35,83 g/tanaman), dengan produksi minyak 64,50 kg/ha/tahun lebih kecil dibandingkan Mear 0012 (79,50 kg/ha/tahun). Kadar total menthol tertinggi
pada Mear 0011 (68,88 %) tetapi kadar minyaknya tidak berbeda, yaitu sebesar 2,21%. Mutu minyak mentha yang berasal dari M. arvensis (minyak cormint) Indonesia masuk alam standar mutu EOA yang dipersyaratkan, khususnya Mear 0010, 0011 dan 0012.
