dc.description.abstractAbstract Population Growth of the Rice Field Rats (Rattus argentiventer) and Its Damage Level on the Rice Crop. The research was aimed to determine the effect of fallow period and rice cultivation on the rice field rat's (Rattus argentiventer) population growth and its damage on rice crops. The research was conducted at the experimental farm of the Indonesian Centre for Rice Research at Sukarnandi, Subang, West Java. Enclosure was established as a rice field block surrounded by "zinc fence" of 90 cm high and 400 m length. The enclosure was divided equally into four blocks of 2,500 m2 each. The treatments were rice crop transplanted once a year (rice-fallow) and that transplanted twice a year (rice-rice) with two replications. Six pairs of adult rats were released in every single treatment plot as initial population if rat. Monitoring of the population was conducted every month using linear trap barrier (LTBS) method. At the end of the experiment, fumigation was conducted in each plot to retrieve all animals for estimating the final rat population. The results indicated that the availability of rice as rat's food is the main factor influencing the increase of the rice field rat population. In the plots, without rice plants control, no rice field rats were observed, meaning that there was no population development of the rats. The level of rat's population was closely related to the intensity of rat damage to rice plants. The intensity of rat dam- age significantly increased during the booting stage of the rice crop. From six couples of rats and its generation led to a 37% of rice damage which was equivalent to the yield loss of 3 t/ha. Abstrak Penelitian bertujuan untuk mempelajari pengaruh periode bera dan periode pertanaman padi terhadap perkembangan populasi tikus sawah (Rattus argentivenler) dan tingkat kerusakan yang ditimbulkan pada pertanaman padi. Penelitian dilaksanakan di Kebun Percobaan BB Padi Sukamandi, Subang, Jawa Barat. Untuk itu dibangun enclo- sure yang merupakan lahan sawah dengan pagar seng tinggi 90 cm dan pagar seng keliling 400 m. Lahan yang dikelilingi pagar seng tersebut (enclosure) terbagi menjadi empat petak, yang masing- masing berukuran 2.500 mz. Perlakuan adalah pertanaman padi satu kali dalam satu tahun (padi-bera) dan pertanaman padi dua kali (padi- padi) dalam satu tahun dengan dua ulangan. Ke dalam setiap petak perlakuan dilepaskan 6 pasang tikus sawah dewasa sebagai perlakuan populasi awal. Pengamatan populasi dilakukan tiap bulan dengan metode linear trap barrier system (LTBS). Pengamatan dilakukan dengan menghitung sarang aktif dan kerusakan tanaman. pada akhir penelitian dilakukan pengamatan populasi semua individu tikus sawah dari tiap petak perlakuan dengan metode empos•gali. Hasil penelitian menunjukkan bahwa faktor utama penyebab peningkatan populasi tikus sawah adalah tersedianya pakan padi. Pada petak perlakuan tanpa pakan tanaman padi, tikus sawah tidak berkernbang biak. Tingkat populasi tikus berhubungan erat dengan intensitas kerusakan tanaman padi. Intensitas kerusakan nyata lebih tinggi terjadi pada periode padi bunting. Enam pasang tikus sawah dan keturunannya selama satu musim tanam padi menyebabkan kerusakan padi sebesar 37% atau setara kehilangan hasil 3 t/ha.
