Abstract

The Effect of Lamtorogung Manure (Leucaena leucocephala) and Planting Spacing on Growth and Yield of Tomatoes (Lycopersicum esculentum Mill.)ABSTRACT. The aim of this study was to find out the effect of dosages of lamtorogung manure and planting spacing, and interaction between them, on both growth and yield of tomatoes. Treatments were arranged by Factorial Completely Randomized Block Design 3 x 3 with 3 replications. Factors evaluated  were dosage of lamtorogung manure (15, 25 and 35 ton ha-1) and planting spacing (50 cm x 60 cm,  50 cm x 70 cm and 50 cm x 80 cm). Variables observed were the height of plant and diameter of the lower end of stem  at 15, 30 and 45 days after planting, the number of fruits per plant  (3 times harvest), the weight of fruits per plant, and diameter of fruit. The result of the study indicated  that dosage of lamtorogung manure of 25 ton ha-1 was the best for the highest tomato yield, and planting spacing of 50 cm x 80 cm was the best for both plants growth and yield. There was no interaction between both treatments towards growth and yield.

Abstract

Comparison of object Oriented Classification With Maximum Likelihood Classification on Land Cover Maaping in District of Gayo LuesABSTRACT. Image classification method used critically effects the classified image produced as well as its accuracy. One of the recently introduced classification methods is Object-Oriented Classification (OOC). The fundamental difference between this method and that of Maximum Likelihood Classification (MLC) lies on the basic unit of image analytical prosses, i.e., image object or segment, and not on a single pixed. The new classification method uses a segmentation procedure with a hierarchical approach which allows an addition of an object  characteristic to other information related  to the classified object, such as from, texture, and context. This object or segment is formed because the smallest region has a larger area than the image pixel. In this study, MLC and OOC classification methods were compered using Landsat ETM+ image for Gayo Lues District of Aceh. The objective of this study was to map out land cover/ landuse classes of the research area and compare the result and its accuracy using the MLC and OOC classification methods. Result  of the study showed that a higher, more detailed, hierarchical land cover/ landuse class with a higher accuracy was obtained using OOC classification method which corresponds better to the contextual condition in the field compared to that of the pixel- based classification method.

Abstract

Perbedaan Varietas Tentang Karakter Daun Bendera Hubungannya dengan Pertumbuhan dan Hasil Padi GogoABSTRAK. Penelitian sebelumnya telah mengungkapkan bahwa daun bendera padi gogo pada kondisi naungan berkorelasi positif dengan hasil. Namun hubungan antara daun bendera dan pertumbuhan serta hasil pada berbagai genotipe padi gogo pada kondisi tanpa naungan masih perlu diteliti lebih lanjut. Oleh karena itu, tujuan dari penelitian ini adalah untuk mengevaluasi perbedaan avrietas dari karakter daun bendera berbagai genotipe padi gogo yang berhubungan dengan pertumbuhan dan hasil serta menghitung korelasi antara karakter daun bendera dan kompoenen pertumbuhan maupun hasil yang nantinya digunakan sebagai indikator seleksi hasil tinggi. Penelitian ini dilaksanakan di Sukoharjo, Tanggamus mulai awal oktober 2002 sampai dengan akhir Maret 2003 dengan menggunakan 18 genotipe padi gogo. Hasil menunjukkan bahwa TB 165-TB-6 mempunyai luas daun bendera dan ukuran biji tertinggi, yaitu berturut-turut 53,1 cm-2 dan 34,3 g/1000 butir. Sebailknya, genotipe dodokan mempunyai luas daun kecil, yaitu 25,8 cm2 dan menunjukkan ukuran biji yang kecil, yaitu 25,7 g/1000 butir. Kondisi ini secara tidak langsung menunjukkan bahwa luas daun bendera berkorelasi positif dengan ukuran biji, yaitu r= 0,31**. Luas daun bendera juga menunjukkan korelasi positif dengan bobot kering batang yaitu r=0,23**. Hal ini berarti bahwa daun bendera mempunyai peran yang penting untuk mengalokasikan fotosintat ke bagian biji. Oleh karena itu, perbedaan varietas untuk daun bendera akan bermanfaat digunakan sebagai indikator seleksi ukuran biji pada padi gogo.
