Judul: Uji daya hasil galur-galur harapan kedelai hitam (Glycine max (L) Merr.) pada lahan sawah di Kabupaten Sumedang, Jawa Barat
Abstrak: Black soybean is important commodity in Indonesia, special for soy sauce. Black soybean have more antosianin and power store more long than yellow soybean. Development food industry raw material from soybean and growth citizen, make demand increase. In spite of national production decrease, so make deficit for soybean. This it make Indonesia to depend with import soybean. Usefull from black soybean for raw material for healthy food and good quality for soy sauce industry. So, black soybean need to increase production and productivity. Increase productivity black soybean can do with to assemble new superior variety high production and adaptability with productive environment like rice field because have first priority in increase national production. In Indonesia, 60% soybean field situated in rice field at dry season I and II. Reseach for get superior variety high production and adaptability with some productive environment did since several years ago in Agronomy dan Horticulture Departement, Bogor Agriculture University. Until now, available black soybean breeding lines for yield trial test. Direction for the reseach is test 33 black soybean breeding lines in rice field in Sumedang Regency, West Java, and identification black soybean breeding lines to can continue for multi location yield trial test.

Judul: Uji daya hasil galur-galur harapan kedelai hitam (Glycine max (L.) Merr) pada lahan sawah di Kabupaten Majalengka
Abstrak: Tujuan penelitian ini adalah (1.) Menguji daya hasil 33 galur harapan kedelai hitam hasil pemuliaan Departemen Agronomi dan Hortikultura IPB pada lahan sawah di Kabupaten Majalengka, Jawa Barat. (2.) Menyeleksi galur-galur yang dapat dilanjutkan pada uji multi lokasi. Penelitian ini dilaksanakan pada bulan April 2010 sampai dengan bulan Juli 2010 di Kabupaten Majalengka. Penelitian ini dilaksanakan dengan menggunakan rancangan kelompok lengkap teracak dengan perlakuan faktor tunggal yaitu terdiri dari 33 galur harapan kedelai hitam. Galur yang digunakan dalam penelitian ini adalah galur SSD-7, SSD-10, SSD-13, SSD-17, SSD-18, SSD-20, SSD-21, SSD-23, SSD-24, SSD-27, SSD-28, SSD-33, SSD-38, SSD-39, SSD-44, SSD-46, SSD-47, SSD-51, SSD-54, SSD-66, SSD-69, SSD-75, SDD-80, SSD-81, SSD-82, SSD-84, SSD-91, SSD-94, SSD-96, SSD-101, SSD-102, dan SC-39-1, serta SC-68-2. Ada 4 varietas pembanding yaitu Sindoro, Cikuray, Ceneng, dan Wilis sebagai pembanding. Masing-masing galur diulang sebanyak tiga ulangan dengan sepuluh tanaman contoh per petak.

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
