Abstract

Chryssanthenum is ornamental plant with variety of shape and color which are unique and appealing. So that, it is in great demand in the community. The production of Chrissanthenum conventionally hampered by availability and quality of seeds. Thus, it needs research through tissue culture. The aim of this research is to know interaction between coconut water and thiamine and to determine the best coconut water and thiamine concentration toward Chryssanthenum micro cuttings. This research used laboratory experimental method by using completely randomized design with two factor. The 1st factor was coconut water concentration consisted of three level which were 5%, 10% and 15%. The 2nd factor was thiamine concentration consisted of three level which were 1mg/L, 2 mg/L and 3 mg/L. From the two factors, those were found that, there were nine combination of treatments and repeated 3 times. The variety  of data was analyzed by using Analysis of Variance (ANOVA) with level of α=5%, and continued by examining Duncan’s Multiple Range Test (DMRT) with level of α=5%. The result indicated that the interaction of coconut water concentration was 5% and thiamine was 1 mg/L on the parameters when growing shoot. There was also interaction on coconut water concentration which was 10 % and thiamine was 1 mg/L on the parameters in the number of shoots. interaction of coconut water combination was 15% and thiamine was 2 mg/L on  fresh weight. The addition of 10% coconut water and 1 mg/L thiamine showed the best result on shoot length.

Abstract

Selada merupakan sayuran yang cukup digemari oleh masyarakat Indonesia. Saat ini permintaan selada dipasaran meningkat, tetapi tidak diimbangi dengan produksinya. Hal ini terjadi karena lahan berkurang akibat alih fungsi lahan. Sistem tanam hidroponik menjadi solusi untuk meningkatkan kualitas dan kuantitas untuk memenuhi kebutuhan pasaran. Pengaturan nutrisi tanaman sistem hidroponik menjadi kunci keberhasilan, sehingga perlu dikaji mengenai konsentrasi nutrisi dan jenis media yang mendukung pertumbuhan tanaman. Tujuan penelitian untuk mengetahui konsentrasi larutan nutrisi AB Mix dan media tanam yang paling baik untuk pertumbuhan dan hasil selada merah dan mengetahui interaksinya. Metode yang digunakan yaitu Rancangan Petak Terbagi (Split plot). Pada Peta utama (main plot) yaitu konsentrasi Nutrisi AB Mix (700, 1000 dan 1300 ppm) dan Anak Petak (sub plot) yaitu media tanam (Rockwool dan spons). Data yang didapatkan dianalisis menggunakan Analysis of Variance (ANOVA) kemudian diuji lanjut menggunakan Uji Beda Nyata Terkecil (BNT) pada taraf 5%. Hasil penelitian yaitu tidak ada interaksi antara perlakuan konsentrasi nutrisi AB Mix dengan macam media tanam tanaman selada pada hidroponik sistem NFT (Nutrient Film Technique). Hasil terbaik pada konsentrasi AB Mix 1300 ppm, terlihat pada parameter volume akar, bobot segar tajuk, bobot segar akar, bobot kering akar dan rasio tajuk akar. Media tanam terbaik yaitu Rockwool, terlihat pada parameter jumlah daun, bobot segar tajuk, tinggi tanaman, bobot segar akar, bobot ekonomis, dan rasio tajuk.
