Abstrak (Berisi Bastraknya saja, Judul dan Nama Tidak Boleh di Masukan)
Abstrak Penelitian ini bertujuan untuk menyelidiki dan membandingkan tingkat kerusakan tanaman kopi akibat serangan hama penggerek buah kopi (Hypothenemus hampei Ferr.) dan penggerek ranting (Xylosandrus sp.) pada dua sistem agroforestri kopi di Lampung Barat, yaitu sistem agroforestri sederhana dan sistem agroforestri kompleks. Pada masing-masing sistem yang diteliti, dilakukan survei terhadap lima hamparan tanaman kopi rakyat. Penelitian dilaksanakan pada bulan Juli – Oktober 2011 di Dusun Talang Bodong, Desa Sukajaya, Kecamatan Sumber Jaya, Kabupaten Lampung Barat. Hasil survei menunjukkan bahwa sistem agroforestri mempengaruhi tingkat serangan hama penggerek buah kopi pada pertanaman kopi. Tingkat serangan tanaman pada sistem agroforestri kompleks mencapai 81 %, sangat nyata lebih rendah daripada tingkat serangan tanaman pada agroforestri sederhana yang mencapai 91 ,8 %. Namun demikian, persentase kerusakan buah akibat serangan penggerek buah kopi pada agroforestri kompleks dan agroforestri sederhana tidak berbeda nyata (Nilai P = 0,05). Tingkat serangan hama penggerek ranting dan kutu tanaman pada sistem agroforestri sederhana juga tidak berbeda nyata dengan sistem agroforestri kompleks (Nilai P = 0,05). Keragaman jenis pohon penaung berkorelasi negatif (r = -0,87) dengan intensitas kerusakan buah. Kata kunci : Hypothenemus hampei Ferrari, penggerek buah kopi, Xylosandrus sp penggerek ranting kopi, sistem agroforestri kopi Abstract The objective of this study was to examine and to compare percentages of crop damages caused by coffee berry borer (Hypothenemus hampei Ferrari) and twig coffee borer (Xylosandrus sp.) on coffee cultivated in two different agroforestry systems i.e complex vs simple agroforestry system. The study was conducted on July to October 2011 by observing small holder coffee fields in Talang Bodong, Sukajaya Village, District of Sumber Jaya, West Lampung. On each agroforesrtry system, five fields were surveyed to determine the damage percentages on coffee berry and plants caused by the two insect pests. Results of the survey showed that the practices of agroforestry systems influenceed the percentages of coffee berry damages on coffee fields. The damage in coffee crops at the complex agroforestry system were 81%, significantly lower compared to 91,8% in the simple agroforestry system. The percentages of coffee berry borer damage, however were not significantly different (P value = 0,05). There was also no significant difference (P value = 0,05) between damages caused by the twig coffee borer and the scale insects in simple and complex agroforestry systems. Shade tree species diversity was negatively correlated (r = -0,87) with the intensity of coffee berry borer damage. Key words : Hypothenemus hampei Ferrari, coffee berry borer, Xylosandrus sp twig coffee borer, coffee-based agroforestry based.
