Judul: Analisis kolaborasi interdisipliner peneliti bidang pertanian: studi kasus penelitian badan litbang pertanian tahun 2004-2006
Abstrak: Peneliti sebagai komunitas pencipta dan pengguna pengetahuan ilmiah mempunyai peran penting dalam penciptaan ilmu melalui penelitian atau kajian ilmiah, dituntut memiliki pengetahuan dan alat-alat serta fasilitas-fasilitas lainnya yang memadai agar dapat mencapai hasil-hasil yang dapat dipertanggungjawabkan secara ilmiah. Badan Penelitian dan Pengembangan Pertanian (Badan Litbang Pertanian) merupakan unit kerja setingkat Eselon I di Departemen Pertanian yang mempunyai tugas melaksanakan penelitian dan pengembangan di bidang pertanian dan merupakan institusi penelitian terbesar di Indonesia. Sejak dibentuk pada tahun 1974, Badan Litbang Pertanian mengalami beberapa kali perubahan dan penyempurnaan. Sampai periode tahun 2008 Badan Litbang Pertanian memiliki 2036 peneliti yang tersebar di 4 Puslitbang, 2 Pusat, 7 Balai Besar, 15 Balai Penelitian, 1 Balai PATP, 31 Balai Pengkajian, dan 3 Loka Penelitian. Salah satu bentuk evaluasi yang dapat dilakukan untuk melihat sampai sejauh mana kegiatan penelitian di Badan Litbang Pertanian telah menstimulasi kerjasama antar peneliti dari berbagai disiplin limu adalah dengan melakukan penelitian dan pengkajian terhadap kegiatan kolaborasi yang telah terjadi dan pengaruh kolaborasi antar disiplin terhadap produktivitas publikasi peneliti. Dengan melakukan evaluasi maka akan diperoleh gambaran mengenai karakteristik, kolaborasi antar disiplin dalam kegiatan penelitian intersidiplin yang dilakukan para peneliti pertanian.

Judul: Analisis Kolaborasi Peneliti berdasarkan Disiplin Ilmu dalam Penelitian Institut Pertanian Bogor dengan Pendekatan Bibliometrik
Abstrak: Researcher collaboration is conducted to create better research results from the combination of knowledge among researchers. One approach to review a collaboration of research is called bibliometric, by applying mathematics and statistics studies in library and information science. This research conducted collaboration analysis for the case study of researches in IPB with data obtained from IPBana 1978-2007, which were divided into 3 periods. Collaboration analysis was performed on each discipline grouped by the Universal Decimal Classification scheme. Subramanyam method was used to calculate each discipline’s collaboration level, whereas Spearman rank correlation was utilized to obtain the correlation between researcher collaboration and research productivity. Based on the calculation, the highest level of collaboration and the highest correlation was in the period of 1988-1997.

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.
