Judul: Analisis akumulasi panas pada perkembangan tanaman cabai Bolivian Rainbow (Capsicum annuum)
Abstrak: Bolivian Rainbow (BR) chilli has four fruit colours that changes according to its level of maturity development. This characteristic makes BR chilli suitable as ornamental pepper rather than consumed. This research aimed to analyze and calculate the heat unit in the development of BR chilli inside and outside the greenhouse. The development of BR chilli is divided into vegetative and generative phases. The average temperature in the greenhouse was 28.0 °C with a maximum temperature of 37.0 ºC. The average temperature outside the greenhouse was 26.3 °C with a maximum temperature of 41.0 ºC. The growing response of BR chilli outside greenhouse in this study was better than its response inside greenhouse. Too high greenhouse temperature was not suitable for the development of BR. Development stage of BR inside greenhouse stopped at FG6 phase with heat unit of 907 ºC. Development stage of BR outside greenhouse could reach until FG14 phase with heat unit of 1470 ºC. The concept of heat unit could not be used to explain the linear correlation between temperature and plant development if the temperatures were not within the optimum temperatures for the plant.

Abstrak: Red pepper (Capsicum annuum L.) is an economically high valued plant which its selling influenced by physical factors such as quality and appearance. Air temperature affects heat unit response and plant phenology which can be used to determine planting period on various environment temperature condition, starting from seed planting until harvesting period. This research aimed to observe temperature and relative humidity vertical profiles around plant canopy and to analyse paranet shading influence toward heat unit and phenology of red pepper plant. The result shows air temperature and relative humidity vertical profile around plant canopy are fluctuative as having lapse rate and inversion pattern at each height.Heat unit of non-shaded and 50%-shaded red pepper plant are 1750 Coday and 2005 Coday respectively (15% greater than without shading). As a whole, using of paranet shading can decrease air temperature by 0.3 oC. Red pepper plant is unsuitable to be planted using 75%-shading because its generative phase become obstructed

Judul: Intrusion Detection System Untuk Pendeteksian Serangan Synflood Pada Protokol TCP/IP
Abstrak: Network Intrusion Detection System (NIDS) adalah pcnycdia pcrlindungan terhadap sistem jaringan komputer sclain dari mekanisme pcrlindungan yang telall diimplementasikan sebelumnya. Firewall scbagai salah satu alternatif pcrlindungan sistem jaringan memiliki kelemahan, yaitu hanya mampu mendcteksi paket data yang keluar dan masuk sistem jaringan yang ingin dilindungi. Pendekatan yang dilakukan oleh IDS adalah dengan melakukan proses audit terhadap segala aktivitas jaringan yang akan dilindungi. Dalam prakteknya, kejadian dalam sistem dinyatakan sebagai seknens dari pakel data yang melintasi atau memiliki tujuan ke sistem jaringan yang akan dilindungi. Penelitian ini mengenali pola serangan SYNflood untuk menentukanfinite state machine yang dapai dipergunakan dalam proses pcndeteksian.
