    Biological control of Oructes rhinoceros using entomopathogen is a promising alternative to the commonly used chemical control, as a part of the integrated pest management in oil palm plantations. The beetle breeds in rotting palm, wood stumps and empty fruit bunches in the field. It is not only a serious pest for young oil palms but for mature palms, especially in peat soil plantations. In some cases the entry hole of the pest on the crown can cause secondary fungy attacks, which cause spear-rot disease. Laboratory trials by Central Plantations Services (CPS) to investigate the growth rates and sporulation capacities of Metarhizium anisopliae showed that 12 days after inoculations, M. aniosoliae had grown fully in petridishes. It then sporulated profusely on corn media in 14 days post inoculation with a population of 2.7 x 109 spores/gram. O. rhinoceros beetle larvae werw obtained from the field and grown in non-sterile empty fruit bunch (EFB) composts, produced using aerated bunker composting anisopliae infected 97% of O.rhinoceros larvae within 14 days. Preliminary field trial was conducted ian a peat soil plantation with a heavy infestation of O.Rhinoceros beetless. The result showed that 88% larvae in the compost were infected within 35 days after treatment with M. anisopliae. The treatment was especially effective when larvae were in the 3rd instars stage. Research had shown that M.anisopliae was effective in controlling O.rhinoceros, our study si the first to show that the fungi can also be inoculated in the EFB compost. Despite their values as organic fertilisers, EFB compost are still not widely used, especially in peat soil plantations, mainly because O. rhinoceros beetles tend to breed in EFB compost. Here the study showed that compost can be used both as organic fertilisers and also as agents for pest control.

    Penerapan Model Pembelajaran Inkuiri Terbimbing untuk Meningkatkan Hasil Belajar IPA Siswa Sekolah Dasar Kelas V SDN 045 Muara Jalai Wirdatul Jannah1, Damanhuri Daud2, Neni Hermita3 Program Studi Pendidikan Guru Sekolah Dasar Jurusan Ilmu Pendidikan Fakultas Keguruan Dan Ilmu Pendidikan Universitas Riau ABSTRACT Problems in this research is the low learning output. The research a purpose to improve science learning outcomes of students through guided inquiry learning model in the Elementary school classroom V 045 Muara Jalai with the number of students 30. The research uses classroom action research design and performed in 2 cycles. Data research is analyzed descriptively. The average value of student learning output has increased, where the average score basis was 67, increased at daily exam I to 75,66 and then increased again at daily exam II to 85,33. It can be concluded that with the implementation of guide inquiry learning model, can improve learning outcomes V grade elementary school students 045 Muara Jalai.
