Tebu (Saccharum officinarum L.) merupakan komoditas perkebunan dan berperan sebagai
bahan baku industri gula. Lahan tebu jarang sekali terjadi ledakan hama (outbreak) karena
peran arthropoda yang beragam. Penelitian ini bertujuan untuk mengetahui jenis-jenis
arthropoda dan perannya yang terdapat pada tanaman tebu di Kabupaten Sleman dan
mengetahui indeks keanekaragaman, indeks kemerataan, dan indeks dominasi arthropoda yang
diperoleh pada lahan tebu. Penelitian dilaksanakan pada bulan Oktober 2023 – Juni 2024, di
lahan Tebu Plant Cane (PC) dan Ratoon Cane (RC) yang beralamat di Planden, Sendangrejo,
Minggir, Sleman dan di Laboratorium Vertebrata Hama, Departemen Hama dan Penyakit
Tumbuhan, Universitas Gadjah Mada, Yogyakarta. Penelitian ini mengamati arthropoda hama
pada tanaman tebu yang diambil dengan metode acak sistematis. Sampel tanaman yang diambil
5 tanaman tebu pada setiap blok. Penelitian ini juga menggunakan perangkap berupa yellow
sticky trap yang dipasang pada kedua lahan (PC) dan (RC). Lahan PC dan RC memiliki 4 blok
dan masing-masing blok dipasang 5 ulangan yellow sticky trap. Perangkap dipasang dengan
interval waktu 1 minggu yang kemudian dipanen dan diidentifikasi morfologi menggunakan
mikroskop digital. Hasil identifikasi dihitung dengan rumus indeks biodiversitas. Hasil
penelitian pengamatan visual arthropoda hama yang diperoleh adalah hama penggerek Chilo
saccariphagus dan Scirpophaga excerptalis. Nilai Indeks Keanekaragaman arthropoda pada
lahan PC tergolong sedang, sedangkan pada lahan RC tergolong tinggi. Indeks Kemerataan
lahan PC sedang, sedangkan lahan RC tinggi. Indeks Dominansi kedua lahan tergolong rendah.
Sugarcane (Saccharum officinarum L.) is a plantation commodity crucial for the sugar
industry. Sugarcane fields rarely experience pest outbreaks due to the diverse roles played by
arthropods. This study aims to identify the types and roles of arthropods found in sugarcane
plants in Sleman Regency, and to determine the diversity index, evenness index, and
dominance index of these arthropods in sugarcane fields. The research was conducted from
October 2023 to June 2024 in Tebu Plant Cane (PC) and Ratoon Cane (RC) fields located at
Planden, Sendangrejo, Minggir, Sleman, as well as in the Vertebrate Pest Laboratory,
Department of Pest and Plant Disease, Gadjah Mada University, Yogyakarta.The study
observed pest arthropods on sugarcane using a systematic random sampling method,
collecting samples from 5 sugarcane plants per block. Yellow sticky traps were also used in
both PC and RC fields, with each having 4 blocks and 5 replicates of traps per block. Traps
were set weekly, harvested, and morphologically identified using a digital microscope.
Biodiversity indices were calculated based on identification results.The visual observation of
pest arthropods identified stem borers such as Chilo sacchariphagus and Scirpophaga
excerptalis. The Arthropod Diversity Index in PC fields was moderate, while in RC fields it
was high. Evenness indices were moderate in PC and high in RC fields. Dominance indices
for both fields were low.
