    (2013-06-17) Elina, Nor; Fitmawati; Iriani, Dyah
    The stomata density of sago increases along with sago growth. The highest starch production is found at nyorong stage. The spiny sago has higher starch production than unspiny sago, therefore it is necessary to characterize the leaf stomata at seedling and nyorong stage. Leaf samples of spiny and unspiny sago were taken from the base of the midrib of three different trees. The stomata observation of upper and lower epidermis of the young leaf was carried out at three different parts i.e. at the base, in the middle and at the tip of the leaf by making paradermal incisions. The result showed that the stomata density of seedling increased at the nyorong stage on both types of sago, however the highest stomata density was only found in the spiny sago. The stomata density showed a reduction from the base to the leaflet tip as well as leaf thickness.

    (2013-02-27) Sujarwati; Iriani, Dyah
    Kelapa sawit merupakan tanatnan primadona di Propinsi Riau. Kelapa sawit tidak hanya dikembangkan oleh perusahaan negara dan swasta tapi juga peikebunan rakyat yang dikelola oleh masyarakat. Data di lapangan menunjukkan kecenderungan peningkatan luas areal perkebunan kelapa sawit, khususnya perkebunan rakyat. (Fauzi, Widyastuti, dan Hartono, 2002). Dengan meningkatnya luas areal perkebunan kelapa sawit maka kebutuhan bibit juga meningkat. Kendala utama yang dihadapi dalam pengadaan bibit kelapa sawit secara generatif adalah lamanya waktu yang dibutuhkan untuk berkecambah. Secara alamiah biji kelapa sawit baru berkecambah 3-4 bulan (Syukur, 1982). Penehtian ini bertujuan untuk menentukan konsentrasi H2SO4 yang dapat mempercepat pericecambahan biji kelapa sawit. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 7 perlakuan dan 4 ulangan. Perlakuan yang digunakan adalah 7 taraf konsentrasi H2SO4 yaitu: Ko: 0% (kontrol), K,: 15%, Kj: 30%, K3: 45%, K4: 60%, K5: 75%, K^: 90%. Perendaman dilakukan selama 15 menit, selanjutnya dilakukan uji perkecambahan. Media perkecambahan terdiri dari campuran tanah kebun, pasir, dan pupuk kandang dengan peibandingan 1:1:2. Parameter yang diamati meliputi viabilitas biji (saat muncul kecambah, persentase perkecambahan, dan kecepatan perkecambahan) serta vigor biji (persentase kecambah normal, abnormal, dan biji mati). Data yang diperoleh dianalisis menggunakan analisis ragam untuk mengetahui pengaruh perlakuan teihadap parameter yang diukur. Hasil analisis ragam yang berbeda nyata diuji lanjut menggunakan Dimcan Multi Range Test (DMRT) pada taraf 5% untuk mengetahui letak beda nyata antar perlakuan.

    Peningkatan Pertumbuhan Stek Cabang Tanaman Mawar (Rosa Damascena Mill) Oleh Rootone F
    (2017-10-13) Lestari, Wahyu; Iriani, Dyah; Rorita, Yeni
    Penelitian tentang penggunaan Rootone F untuk meningkatkan pertumbuhan stek cabang tanaman mawar (Rosa damaccena Mill) telah dilakukan. Tujuan penelitian adalah untuk mengetahui konsentrasi Rootone F dan lama perendaman yang optimal untuk pertumbuhan stek cabang tanaman mawar. Penelitian menggunakan rancangan acak lengkap faktorial, faktor pertama dalah tingkatan konsentrasi Rootone F (0, 600, 800, 1000, dan 1200 ppm) dan faktor ke dua adalah lama perendaman bahan stek dalam larutan Rootone F (30, 60, dan 90 menit). Hasil yang diperoleh dari penelitian adalah perlakuan lama perendaman dan interaksi antara lama perendaman dan tingkatan konsentrasi Rootone F tidak menunjukkan hasil yang berbeda nyata pada semua parameter, sedangkan untuk perlakuan tingkatan konsentrasi hanya pada parameter saat muncul tunas dan % stek yang tumbuh. Berbeda nyatanya panjang akar, berat basah akar dan berat kering akar disebabkan Rootone F merupakan zat pemicu pertumbuhan yang sangat berperan untuk mempercepat pembentukan akar sehingga perbedaan tingkatan konsentrasi akan memberikan respon yang berbeda terhadap kemampuan Rootone F untuk membantu stek dalam menstimulasi pembentukan akar adventifnya. Pemberian Rootone F dengan konsentrasi 600 ppm adalah konsentrasi optimal untuk meningkatkan pertumbuhan stek tanaman mawar.
