Chemical grafting of Polyaniline (PAni) and chitosan (CS) as has been carried out with formaldehyde as grafting agent and ammonium persulfate as an initiator. For this reason aniline monomers were copolymerized with chitosan and were chemically polymerized. The synthesized copolymer was Characterized using Fourier transform infrared spectroscopy (FTIR), UV-Visible, scanning electron microscopy ...

Competition or facilitation characterises intra- and interspecific interactions within communities of species that utilize the same resources. Temperature is an important factor influencing those interactions and eventual outcomes. The noctuid stemborers, Busseola fusca and Sesamia calamistis and the crambid Chilo partellus attack maize in sub-Saharan Africa. They often occur as a community of ...

Penyambungan (grafting) merupakan salah satu upaya untuk memperbaiki sifat tanaman menggunakan bahan klonal baik pada fase pembibitan, pemeliharaan maupun rehabilitasi. Keragaan kopi Robusta dapat diperbaiki melalui penyambungan intraspesifik (Robusta/Robusta) menghasilkan produktivitas yang lebih tinggi atau interspesifik (Arabika/Robusta) Arabika. Tujuan penelitian ini adalah (1) mengetahui p...
