Abstrak: Salah satu tanaman florikultura yang bernilai ekonomi tinggi adalah tanaman krisan. Kehadiran hama yang menyebabkan kerusakan pada tanaman krisan menjadi faktor pembatas dalam budi daya krisan. Penelitian bertujuan mengetahui kelimpahan hama dan musuh alami, gejala kerusakan yang diakibatkan, serta luas serangan hama pada 3 varietas tanaman krisan di PT Natalia Nursery, Tenjolaya, Bogor. Penelitian dilakukan pada 3 petak pertanaman krisan. Pengamatan dilakukan secara langsung pada tanaman contoh yang ditentukan secara sistematis pada tiap petak dan pemasangan perangkap rekat kuning. Hama dan musuh alami yang ditemukan kemudian diidentifikasi. Hama yang ditemukan menyebabkan kerusakan pada tanaman krisan yaitu Thrips parvispinus, Aphis gossypii, Bemisia tabaci, Spodoptera litura, dan pengorok daun. T. parvispinus, A. gossypii, B. tabaci, dan S. litura dominan terdapat pada varietas fiji kuning dengan proporsi kelimpahan berturut-turut yaitu 24,12%, 12,81%, 4,52%, dan 3,14%. Luas serangan S. litura, T. parvispinus, dan pengorok daun pada krisan varietas fiji kuning lebih tinggi dibandingkan dengan varietas reagen putih dan towntalk. Berdasarkan metode pengamatan secara langsung, musuh alami dominan ditemukan pada krisan varietas fiji kuning dengan proporsi kelimpahan M. sexmaculatus (31,82%), Coelophora sp. 1 (9,09%), Coelophora sp. 2 (9,09%), Pardosa sp. 1 (0,00%), Pardosa sp. 2 (4,55%), dan Oxyopes sp. 1 (9,09%). Proporsi kelimpahan dari Telenomus sp. 1, Ichneumonidae sp. 1, Ichneumonidae sp. 2, M. sexmaculatus, Coelophora sp. 1, dan Coelophora sp. 2 yang didapatkan dari pemasangan perangkap berturut-turut yaitu 56,00%, 12,00%, 8,00%, 8,00%, 8,00%, dan 8,00%.

ILOSmedia also uses the Realtime kernel as kernal Mutimedia. ILOSmedia testing is performed by 11 students of Computer Science who are members of FOKERZ community. The testing process is performed by executing ILOSmedia via live-cd and filled in a questionnaire. The test result shows that ILOSmedia has hardware compatibility on notebook and PC with good performance. As much as 72.727% of respondents believe that the size of the installer ILOSmedia of 1.34 GB and a minimum 10GB hard drive is normal. ILOSmedia has multimedia packages complete with the percentage completeness according to respondents is 45.455% are very complete and 54.545% are complete.
