dc.description.abstractMangaraja S P Lumban Gaol, “The Study of Concentration of Chitosan to Control Termites (Coptotermes curvignathus Holmgren) in the rubber plants at the field supervised by Syahrial Oemry and Yuswani Pangestiningsih. This research was conducted in experiment field of Sungei Putih Research Centre since March until June 2014. The aim of the research was to know the most effective of chitosan consentration to control termites (Coptotermes curvignathus Holmgren) in the rubber plants at the field. This research used the method of Randomized Block Design with Non Factorial. The test of chitosan concentration with 6 treatments and 3 replicates i.e : K0 (control), K1 (2%), K2 (4%), K3 (6%), K4 (8%) and K5 (10%) with bait aplication. The parameters were observe is the percentage of termites mortality (Coptotermes curvignathus Holmgren) and symptoms of infection. The highest result showed that percentage of termites mortality are 100% at K3 treatment and the low result are 18,67% at K0 (control). It showed was sixth day after application. The symptoms of chitosan infections was characterized by discoloration of the abdomen which was originally white to blackish brown. The most effective of chitosan concentrate to control termites in field is 6% at K3 treatment.en_US
dc.description.abstractMangaraja S P Lumban Gaol, “Uji konsentrasi kitosan untuk mengendalikan rayap (Coptotermes curvignathus Holmgren) pada tanaman karet di Lapangan” di bawah bimbingan Syahrial Oemry dan Yuswani Pangestiningsih. Penelitian dilakukan di Kebun Percobaan Balai Penelitian Karet Sungei Putih dari Maret sampai Juni 2014. Tujuan penelitian ini untuk mengetahui konsentrasi kitosan yang paling efektif untuk mengendalikan rayap (Coptotermes curvignathus) pada tanaman karet di lapangan. Metode yang digunakan pada penelitian ini adalah Rancangan Acak Kelompok Non Faktorial. Uji konsentrasi kitosan dengan 6 perlakuan (0, 2, 4, 6, 8 dan 10%) yang diberikan dengan cara mengumpan dan tiga ulangan. Hasil penelitian menunjukkan persentase mortalitas rayap tertinggi (100%) pada perlakuan 6% kitosan dan terendah (18,67%) pada Kontrol 6 hari setelah aplikasi. Gejala infeksi kitosan ditandai dengan perubahan warna abdomen yang semula berwarna putih menjadi coklat kehitaman.en_US
