Efektivitas Beberapa Rodentisida Nabati terhadap Tikus Sawah (Rattus argentiventer Robb and Kloss) di Laboratorium

ABSTRACT
WELISARI PURBA : Efektivity some Plants Rodenticides to Rat(Rattus
argentiventerRobb and Kloss) at Laboratory, supervised by Suzanna Fitriany
Sitepu and Lahmuddin Lubis. Rat (Rattus argentiventer Robb and Kloss) is one of
the important plant pests in rice fields. Damage caused by rats attack on rice
crops in Indonesia reached a loss of 15-20% every year. This research was
conducted to testing there is influence addition some plants rodenticides to
mortality of rat(R.argentiventer) at Laboratory.The experiment was conducted at
Laboratory of Vertebrate Pest Control Balai Besar Perbenihan dan Proteksi
Tanaman Perkebunan, Medan from March to May 2016. This research was
designed by non-factorial randomized block with 5 treatments is control,
Dioscorea hispida, Nicotiana tabacum, Jatropha curcas, Ageratum conyzoides in
30%and each of which in repeated four times.Observations included the weight
of rat, consumed of bait,change of behaviour and persentage of mortality. The
results showed that the highest reduction weight of rat was at Nicotiana tabacum
(3,37gr) and the lowest was at Ageratum conyzoides (0,37gr). The highest
consumed level of bait was at Dioscorea hispida (8,22gr) dan the lowest was
atNicotiana tabacum (1,07gr). The highest change of behaviour was Dioscorea
hispida (36) and the lowest was Jatropha curcas (18). The highest mortality was
at Dioscorea hispida (100%) dan lowest was at Jatropha curcas (25%).

LaboratoriumdibimbingolehSuzanna Fitriany SitepudanLahmuddin Lubis.Tikus
sawah(Rattus argentiventerRobb and Kloss)merupakan salah satu hama penting
pada tanaman padi. Kerusakan akibatserangan tikus pada tanaman padi di
Indonesia mencapai kerugian sebesar 15-20%setiap tahunnya.Tujuan penelitian
ini untuk menguji adanya pengaruh pemberian beberapa rodentisida nabati
terhadap mortalitas tikus sawah (Rattus argentiventerRobb and Kloss) di
laboratorium.Penelitian ini dilaksanakan di Laboratorium Pengendalian Hama
Vertebrata (LPHV)Balai Besar Perbenihan dan Proteksi Tanaman Perkebunan

(B2P2TP), Medan dari bulan Maret sampai Mei 2016.Rancangan percobaan yang
digunakan adalah Rancangan AcakKelompok (RAK) non faktorial dengan 5
perlakuan yaitu perlakuankontrol,Dioscorea hispida, Nicotiana tabacum,
Jatropha curcas, Ageratum conyzoides dengan konsentrasi 30% yang masingmasing diulang sebanyak empat kali.Pengamatan meliputi bobot badan tikus,
tingkat konsumsi pakan umpan, perubahan tingkah laku tikus dan persentase
mortalitas tikus. Hasil penelitianmenunjukkan bahwa penurunan bobot tubuh
tertinggi teerdapat pada Nicotiana tabacum (3,37gr) dan terendah Ageratum
conyzoides (0,37gr). Tingkat konsumsi umpan tertinggi terdapat pada Dioscorea
hispida (8,22gr) dan terendah Nicotiana tabacum (1,07gr). Perubahan tingkah
laku tertinggi terdapat pada Dioscorea hispida (36) dan terendah Jatropha curcas
(18). Persentase mortalitas tertinggi terdapat pada Dioscorea hispida (100%) dan
terendah Jatropha curcas (25%).
