Inisiasi Dan Aklimatisasi Tanaman Kayu Putih (Melaleuca cajuputi) Hasil Perbanyakan Secara in-Vitro Pada Dua Jenis Media Dengan Berbagai Konsentrasi Sitokinin
Get PDFThis research was aimed to determine the best based medium containing BAP in Melaleuca cajuputi propagation at the initiation stage, and to obtain the best growth of cajuputi plantlets during acclimatization stage. The experiment was arranged in completely randomized design, which consists of two experimental stage, cajuputi bud initiation and cajuputi plantlet acclimatization. At the initiation stage, the tested treatment were combination of based medium (WPM and MS) and Cytokinin (BAP). While at the acclimatization stage, plantlets from each treatment of initiation stage were grown in soil medium. This research was conducted over May to December 2014 at the Laboratory of Forest Biotechnology, Forestry Faculty Tadulako University. Data were analyzed by Analysis of Varian and the differences between treatments were determined by Duncan Multiple Range Test (DMRT). The outcome of this research showed that WPM based medium containing 0.7 ppm BAP had the best responses to the growth of cajuputi planlet (Melaleuca cajuputi) at the initiation stage. Application of Woody Plant Medium (WPM) based medium contained 0.7 ppm BAP at the initiation stage, give the optimal responses to the growth of Eucalyptus planlet (Melaleuca cajuputi) during the acclimatitation stage
Analisis Produksi Dan Pendapatan Usahatani Padi Sawah Metode System Of Rice Intensification Di Kecamatan Sindue Kabupaten Donggala
Get PDFThis research aimed at finding out the influence of factors in line with land area factor, seed, Urea fertilizer, Phonska fertilizer, Seprit fertilizer and labours toward the production of rice field cultivated with System of Rice Intensification (SRI) method at Lero Tataro Village, Sindue district, Donggala regency. The 40 respondents were taken through census method. A multiple linier regression was used to analyze the data. The results showed that the independent variable (Xi) gave a big influence toward the dependent variable (Y). The coefficient of determination (R2) was 0.979 which means that 98 percent of the variations of rice field’s production can be explained by the variable of land area (X1), seed (X2), Urea fertilizer (X3), Phonska fertilizer (X4), Seprit fertilizer (X5), and the labour (X6). The other 2 percent was explained out of the model. It can be said that farm production through System of Rice Intensification (SRI) method at Lero Tatari village were obviously influenced by the land area, seed, Urea fertilizer, Phonska fertilizer, Seprit fertilizer, and labours. The income of farm production using System of Rice Intensification (SRI) Method at Lero Tatari, Sindue district was Rp. 13.023.005.88/0.76 ha, or Rp. 17.079.351.97/ha
