Judul: Biologi Hyposidra talacaWlk. pada Beberapa Jenis Tanaman di sekitar Perkebunan Teh Gunung Mas PTPN VIII Bogor
Abstrak: Hyposidra talaca is one of the most important pest in tea plantation and can cause significant yield losses. To effectively control the pest we need, the biology of H. talaca needs to be understood. This study aimed to determine the effect of tea, suren, sengon, cinnamon, and sintrong leaves on the biology of H. talaca. The insect were reared on different host plants and were observed for longevity, fecundity, fertility, mortality, and feed consumtion. The longevity of male H. talaca on tea, suren, sengon, cinnamon, and sintrong are 62.13, 63.68, 63.09, 62.23, and 46.46 days respectively and the longevity of females H. talaca on tea, suren, sengon, cinnamon, and sintong are 58.66, 59.21, 58.89, 57.37, and 31.89 days respectively. The fecundity of H. talaca on tea, suren, sengon, cinnamon, and sintrong are 2720.67, 1967.33, 1482.67, 2872.33, and 2009.33 eggs respectively, while the fertility H. talaca on tea, suren, sengon, cinnamon, and sintrong are 84.00, 84.67, 75.00, 90.67, and 86.33 % respectively. The average rate of mortality in the life cycles of H. talaca on tea, suren, sengon, cinnamon, and sintrong are 5.5, 10.56, 13.33, 15.55, and 10.01 % respectively. Average total feed consumption rate of larvae of H. talaca on tea, suren, sengon, cinnamon, and sintrong are 1.97, 0.98, 0.77, 2.29, and 1.32 g respectively.

Judul: Pengelolaan Kebun dan Upaya Pengendalian Hama Ulat Jengkal (Hypiosidra talaca) dengan Aplikasi Hyposidra talaca Nucleopolyhedrovirus pada Tanaman Teh di PT Perkebunan .Nusantara VIII Gunung Mas Bogor, Jawa Barat.
Abstrak: The objectives of this study is to understand the management of plant maintenance of tea plantation at PT Perkebunan Nusantara VIII Gunung Mas and to propose an alternative pest control for tea looper (Hyposidra talaca) utilizing Hyposidra talaca Nucleopolyhedrovirus (HtNPV). The methods used were interviews, observation in the field, and the field efficacy test of HtNPV directly on tea plants. Tea plant maintenance activities include trimming, fertilizing, plucking, weed control, and pests-diseases management. Poor sanitary condition of tea plantation and the low human resources became limiting factors in the field. The most important pest at PT Perkebunan Nusantara VIII Gunung Mas is tea looper (Hyposidra talaca) that feed on tea shoots and may reduce production to more than 40%. Alternative control measure for H. talaca using HtNPV can be carried out by spraying HtNPV suspension. Effective application of HtNPV was applied twice per week and were able to reduce the population of H. talaca to more than 50% within 7 days, and can reduce the population up to 100% within 11 days.

Abstrak: Array lighting uses a group of lights behaving and functioning as a single light. This method can be used to simulate the effect of global illumination in less time. In this research, Cylight, an array-based 3D lighting tool with tubular geometry, is developed using MAXScript. The image quality comparison to global illumination using Scanline and mental ray is conducted through an online survey using six 3D scenes. 98 respondents participated to determine the realistic level for each rendered scene with a value between 1 to 5. The rendering time is also measured. The results show that Scanline produces the best image quality, but not significantly different compared to Cylight. On the other hand, Cylight is significantly faster, taking less than 10% of Scanline's rendering time.
