Saya yang bertanda tangan dibawah ini, mahasiswa Fakultas Pertanian

Universitas Jember :

Nama

: Anton Pujanang

NIM

: 051510401023

Menyatakan dengan sesungguhnya bahwa karya tulis ilmiah yang berjudul ”

Analisis Periode Kritis dan Tipe Serangan Hama Wereng Batang Coklat

(

Nilaparvata lugens

Stal.) di Kecamatan Rambipuji Kabupaten Jember” adalah

benar hasil karya sendiri, kecuali kutipan yang sudah saya sebutkan sumbernya,

belum pernah diajukan pada institusi mana pun, dan bukan karya jiplakan. Saya

bertanggung jawab atas keabsahan dan kebenaran isinya sesuai dengan sikap

ilmiah yang harus dijunjung tinggi.

Demikian pernyataan ini saya buat dengan sebenarnya, tanpa ada tekanan

dan paksaan dari pihak mana pun serta bersedia mendapat sanksi akademik jika

ternyata di kemudian hari pernyataan ini tidak benar.
