Effectiveness trial of pheromone traps against Oryctes rhinoceros L. and its damage intensity on coconut tree at Batulahat Village, Nusaniwe District, Ambon IslandThe research aimed to determine the efficacy of traps containing pheromone in catching the coconut pest, coconut rhinoceros beetle (Oryctes rhinoceros L.) and its effect on reducing the damage severity caused by the pest. The experiment was conducted by observing the damage intensity before treatment and continued with the efficacy testing of the traps containing pheromone (Ethyl 4-methyloctanoate) against the population of the coconut rhinoceros beetle. The damage intensity was measured following the traps treatment. The result demonstrated that the average of damage intensity before and after treatment were 13.33% and 9.61%, respectively. This indicated the effectiveness of traps in catching the coconut rhinoceros beetle. The number of O. rhinoceros caught during the experiment was analysed using quantitative analysis model. The highest number of coconut rhinoceros beetle caught was 9 bettles/2 months at traps containing pheromone. Whilst, the number of coconut rhinoceros beetle caught at traps containing pheromone with lamp demonstrated lower number of coconut rhinoceros beetle. Furthermore, the lower damage intensity at the experimental location was categorized as low. This was due to good agricultural practice implemented by the farmer.Keywords: Coconut, Pheromone, Damage intensityABSTRAKPenelitian ini bertujuan untuk mengetahui keefektifan perangkap feromon dalam memerangkap hama Oryctes rhinoceros L. dan pengaruhnya terhadap intensitas kerusakan yang disebabkan oleh hama tersebut. Penelitian dilakukan dengan menghitung Intensitas Kerusakan (IK) yang disebabkan oleh hama O. rhinoceros dan dilanjutkan dengan menguji efektivitas perangkap feromon (Ethyl 4-methyloctanoate) terhadap perkembangan populasi hama tersebut. Intensitas kerusakan dihitung dengan menggunakan formula IK untuk tanaman yang terserang dan yang tidak terserang O. rhinoceros sebelum dan sesudah aplikasi feromon. Hasil penelitian menunjukkan rerata IK sebelum dan sesudah aplikasi feromon masing-masing sebesar 13,33% dan 9,61%. Terjadi penurunan IK karena efektivitas feromon dapat memerangkap hama O.rhinoceros. Jumlah tangkapan O. rhinoceros tiap perlakuan dianalisa dengan model analisis kuantitatif sederhana. Jumlah tangkapan O. rhinoceros terbanyak dengan rerata tangkapan 9 ekor/2 bulan atau sama dengan 4,75 ekor/bulan pada perangkap berferomon saja. Sementara perangkap feromon dan lampu menghasilkan jumlah tangkapan hama O. rhinoceros yang lebih rendah. Lebih lanjut, rerata IK hama O. rhinoceros di desa Latuhalat tergolong kategori ringan karena sistem kultur teknik dari petani setempat sudah dilakukan dengan baik sehingga areal pertanaman kelapa cukup terawat.Kata Kunci: Kelapa, Feromon, Intensitas kerusakan

Since ancient times, sago grubs have been consumed by people in many places including Maluku, Papua and Borneo in various processed forms. People who own sago forests/plantations or reside in places with sago forests currently still eat sago worms as a supplement to their diet. Sago grub, larva of red palm weevil (Rhynchophorus ferrugineus Olivier), is a pest majorly on sago and others palm trees. The objective of this study was to obtain data on the life cycle of the insect in the laboratory and to determine the nutritional content of sago grubs as a reference for the utilization of sago grubs. as an alternative source of protein for human as well as livestock. The results showed that egg stage take place in 3-5 days, larvae consists of 5 instars and take place in about 60-72 days. The pupal stage take place in about 16-20 days, the total life cycle of insect in the laboratory is 89.3 days. The 4th and 5th instar larvae have nutritional composition including carbohydrate, protein, fat, minerals and vitamins. They contain 27.97% protein, all (9) essential amino acids, 59.71% fat with three unsaturated fatty acids including the essential fatty acids : omega 3 and omega 6. Therefore, they have the potential to be cultivated as natural source of animal protein for human and livestock.

Hama penggerek buah kakao/PBK (Conopomorpha cramerella Snell.) merupakan salah satu hama yang pada tingkat serangan berat dapat mengakibatkan kehilangan hasil kakao mencapai 90%. Penelitian ini bertujuan untuk menguji teknologi pengendalian hama PBK yang ramah lingkungan yaitu penggunaan perangkap feromon seks pada aspek posisi ketinggian perangkap yang efektif. Penelitian dilaksanakan di desa Banda Lama, Kecamatan Amahai, Kabupaten Maluku Tengah yang berlangsung dari bulan Januari sampai Maret 2019. Penelitian ini menguji ketinggian perangkap feromon pada tiga posisi ketinggian perangkap feromon yang berbeda yaitu ketinggian 1 m, 2 m dan 3 m. Data yang diambil adalah jumlah tangkapan imago C. cramerella tiap perlakuan. Hasil penelitian menunjukkan bahwa perangkap feromon dengan ketinggian 1 m yang paling efektif memerangkap hama PBK dengan jumlah tangkapan 85 ekor dan rerata populasi imago terperangkap adalah 10,63 ekor/bulan.
