Abstrak: Yellowstripe scad (Selaroides leptolepis) is an important economic value fish as one of target species by fishermen in PPN Karangantu. The purpose of this research is to assess the condition of yellowstipe scad stocks in the Gulf of Banten. The research was conducted in May to August 2012. Total number of fish taken during the research were 728 individuals. The results showed that the yellowstripe scad have isometric growth pattern. Size at first maturity of yellowstripe scad was 146 mm with peak spawning occurs in August. Yellowstripe scad exploitation rate has exceeded the optimum exploitation rate that yellowstripe scad in the Gulf of Banten allegedly already overfished. Management measure that can be suggested is through setting dogol mesh sizes and fishing season closure to achieve sustainable use of this resources

Abstrak: Yellowstripe Scad is one of pelagic fishes has the value of economically important fish catches and is dominant in PPP Labuan. Population of yellowstripe scade feared will decline arrest of conducted in continous. The purpose of this study was to assess the condition of yellowstripe scad in Sunda Strait that include of growth, mortality and exploitation rate. The study is done at PPP Labuan on Juny-October 2013. Fish samples observed reach a 752 with length range between 81-168 mm. Yellowstripe scad have allometric negative growth and a size of first maturity 157 mm. Parameter growth allegedly used method Ford Walford showed growth yellowstripe scade female faster than male with growth rate each of 0,42 and 0,36. The exploitation of yellowstripe scad has exceeded the optimum exploitation rate that yellowstripe scad in Sunda Strait has over exploited. Optimum efforts allegedly used Schaefer model showing of 1089 trip/year with maksimum sustainable yield (MSY) of 1977 tonnes/year and total allowable catch 1423 tonnes/year. Management that can be suggested is setting fishing effort and mesh size more than 6 cm.

Judul: Comparison of HIV Model with and without Time Delay
Abstrak: Acquired immunodeficiency syndrome (AIDS) is the reduction of the human immune system. AIDS is caused by human immunodeficiency virus (HIV). No medicine has been found for this desease until recently. An AIDS therapy is usually performed with highly active antiretroviral therapy, namely reverse transcriptase inhibitors, protease inhibitors and combination of both. Various models have been developed to explain the immune system of patients with AIDS, namely the HIV, response and the time delay model. This paper discusses the comparison between the dynamics of the HIV virus, the dynamic response of protease inhibitors and dynamics of time delay. The dynamics model of HIV is influenced by the level of white blood cells produced and the rate of its death. Dynamics of protease inhibitors on the response and the time delay model is influenced by the death rate of infected white blood cells and the failure rate of treatment.
