Keanekaragaman Serangga di Atas Permukaan Tanah Pada Tanaman Jambu Air (Syzygium samarangense) (Blume) Merr. & Perry) dan Jambu Biji (Psidium guajava L.) di Lapangan

ABSTRAK
ABDUL MUIN: “Keanekaragaman Serangga Permukaan Tanah Pada
Tanaman Jambu Air (Syzygium samarangense) (Blume) Merr. & Perry) dan
Jambu Biji (Psidium guajava L.) Di Lapangan” di bawah bimbingan MARHENI
dan HASANUDDIN.
Penelitian ini bertujuan untuk mengetahui jenis, kerapatan dan frekuensi
kehadiran serta indeks keanekaragaman pada serangga di lahan pertanaman
Jambu Air (Syzygium samarangense) dan Jambu Biji (Psidium guajava L.).
Penelitian dilaksanakan di di Kelurahan Jati Utomo, Kecamatan Binjai Utara,
Kota Binjai dan Desa Durin Jengak, kecamatan Pancur Batu, Kabupaten Deli
Serdang dan Laboratorium Hama dan Penyakit Tumbuhan, Fakultas Pertanian,
Sumatera Utara, Medan pada bulan Januari sampai April 2016. Penelitian ini
menggunakan 3 teknik perangkap serangga (Sweep Net, Yellow Sticky Trap dan
Handpicking), dan diulang sebanyak lima kali.
Hasil penelitian menunjukkan serangga yang tertangkap pada lahan jambu
biji terdapat dari 11 ordo dan 41 famili, nilai Kerapatan relatif tertinggi sebesar
11.43%, yang terendah sebesar 0.08% dan indeks keanekaragaman ShanonWeiner (H’) 3.19 (sedang) sedangkan pada lahan jambu air terdapat 9 ordo 30
famili dengan nilai Kerapatan Relatif tertinggi sebesar 17.75%, yang terendah
sebesar 0,12% dan nilai indeks keanekaragaman serangga sebesar 2,82 (sedang).

ABSTRACT
Abdul Muin: "Diversity Insect Land Surface Water On Guava Plants (Syzygium
samarangense) (Blume) Merr. & Perry) and Guava (Psidium guajava L.) In the
Field "under the guidance MARHENI and HASANUDDIN.
This study aims to determine the type, density and frequency of attendance as well
as the index of diversity of insects in cropping land Jambu Air Plants (Syzygium
samarangense) and Guava. The research was conducted in the village district,
Jati Otomo, Binjai Barat, Binjai city and Desa Durin Jengak, Pancur Batu subdistrict, Deli Serdang and Plant Pests and Diseases Laboratory, Faculty of
Agriculture, North Sumatra, Medan in January and May 2016. This study
43techniques using insect traps (Sweep Net,
Yellow Sticky trap and
Handpicking), and is repeated five times.
The results showed the insects were caught on land guava are of 11 orders and 41
families, value Relative density high of 11.43%, the lowest is 0.08% and the
diversity index Shannon-Weiner (H ') 3.19 (moderate), while on land guava there

are nine orders of 30 families with the highest value of Relative density
amounting to 17.75%, the lowest of 0.12% and insect diversity index value by
2.82 (moderate).
