Abstract

Penelitian ini bertujuan mendapatkan ketahanan segar bunga anggrek dendrobium pot di rumah sere penyinaran 55%. Penelitian dilaksanakan di Balai Penelitian Tanaman Hias Jakarta dari bulan Juli 1998 sampai bulan April 1999. Tanaman pot anggrek Dendrobium berbunga yang digunakan dalam penelitian merupakan tanaman yang berbunga pertama atau kedua. Tingkat kemekaran bunga yang dicoba  terdiri dari lima taraf yaitu 0-5% bunga mekar, 25–30% bunga mekar, 45–50% bunga mekar, 70–75% bunga mekar dan 90–95% bunga mekar. Pengangkutan dilakukan menggunakan mobil berpendingin (suhu 10-130C; RH 75-100%) selama 10 jam (±308,3 km). Penelitian dilakukan dengan rancangan acak lengkap, pola faktorial dengan 3 ulangan. Hasil penelitian menunjukkan bahwa tingkat kemekaran bunga 0-5% baik  untuk kultivar anggrek Dendrobium Bandung Pink maupun kultivar Dendrobium Sakura White masing-masing mempunyai umur kesegaran 36,4 dan 37,9 hari dengan persentase kemekaran bunga 87,5% dan 92,5%, waktu kemekaran bunga maksimum 17,7 dan 18,3 hari, bunga pertama layu 12,9 dan 14,5 hari. Perlakuan tersebut dapat mempertahankan kualitas bunga tetap prima dan dapat memperpanjang masa kesegaran tanaman pot berbunga setelah pengangkutan.The experiment was conducted to find out the flower shelf-life of potted Dendrobium at screenhouse. The experiment was done at Research Institute of Ornamentals Plant Jakarta from July 1998 to April 1999. Potted Dendrobium used in the experiment was bearing first or second flowers. In this experiment, five blooming stages (0-5%, 25-30%, 45-50%, 70-75%, and 90-95% bud opening) of Dendrobium orchid were used. Potted plants were transported from Jakarta–Bandung vice-versa using refrigated vehicle (10-13oC of temperature and 75-100% RH) for about 10 hours (±308.3 km). The experiment was arranged in a factorial completely randomized design with 3 replications. The results of the experiment indicated that potted Dendrobium cultivar Bandung Pink and Sakura White with blooming stage of 0-5% gave the best keeping quality with percentage of bud opening 85.7 and 92.5%, time of maximal blooming 17.7 and 18.3 days, time of first wilting flowers 12.9 and 14.5 days, and shelf-life 36.4 and 37.9 days respectively. By applying those treatment the period of potted plant flower shelf-life could be extended and quality after transportation could be maintained.

Abstract

ABSTRAK. Penelitian dilaksanakan di Laboratorium Balai Penelitian Tanaman Hias Jakarta dari bulan Juni 1998 sampai bulan Mei 1999. Penelitian bertujuan memperoleh jenis dan komposisi lemak hewan yang tepat untuk proses enfleurasi minyak mawar. Teknik enfleurasi dalam proses pembuatan minyak mawar dicoba dengan bahan dasar bunga mawar merah tabur asal Bandungan, Jawa Tengah. Penelitian menggunakan rancangan acak lengkap faktorial dengan 3 ulangan. Perlakuan yang diuji adalah (a) campuran lemak sapi + lemak ayam (1:1; 1:2; 1:3, 2:1, dan 3:1), (b) campuran lemak kambing dan lemak ayam (1:1, 1:2, 1:3, 2:1, dan 3:1), dan (c) campuran lemak sapi + kambing + ayam (2:1:0,5 dan 2:1:1). Hasil penelitian menunjukkan bahwa perlakuan yang terbaik adalah campuran lemak hewan dengan perbandingan lemak sapi:lemak kambing:lemak ayam sebesar 2:1:1, yang mempunyai tingkat kekerasan 13,2 mm/5 detik/50 g pemberat, dan bertekstur halus. Rendemen absolut yang dihasilkan mencapai 0,076-0,174% dengan indeks bias 1,46-1,53 dan komponen utama penyusun absolut mawar adalah fenil etil alkohol (11,76-22,34%), sitronelol (2,71-6,05%), dan geraniol (3,37-4,99%). Teknik enfleurasi dapat digunakan dalam produksi minyak mawar bermutu.ABSTRACT. Yulianingsih, D. Amiarsi, and Sabari S. 2007. The Enfleuration Tehnique for Producing Rose Oil. The research was conducted at Indonesian Ornamental Plant Research Institute Laboratory in Jakarta from June 1998 to May 1999. The aim of the experiment was to find out the appropriate composition and kinds of animal fat for enfleuration process for producing rose oil. The enfleuration technique was used to produce volatile oil from red rose flowers from Bandungan, Central Java. Experiment was arranged in a factorial completely randomized design with 3 replications. The treatments were (a) mixture of animal fat of cow + chicken with ratio (1:1, 1:2, 1:3, 2:1, and 3:1), (b) mixture of animal fat of goat + chicken (1:1, 1:2, 1:3, 2:1, and 3:1), and (c) mixture of animal fat of cow + goat + chicken (2:1:0,5 and 2:1:1). The results of the experiment indicated that the best treatment was absorbent mixture of animal fat of cow, goat, and chicken with ratio of 2:1:1 with consistency of 13.2 mm/5 sec/50 g ballast, soft enough, and smooth texture. The rendement of absolute was about 0.076-0.174%, with refraction index 1.46-1.53, and the main components were phenyl ethyl alcohol (11.76-22.34%), citronellol (2.71-6.05%), and geraniol (3.37-4.99%). This enfleuration technique can be used to produce rose absolute with high quality.
