Judul: Potensi Hijauan Lokal Pesisir Pantai bagi Ternak Ruminansia di Desa Mangunlegi Kecamatan Batangan Kabupaten Pati
Abstrak: Coastal area has many grass species diversity which can be used as feed for ruminant livestock. The result of botanical composition analysis by “dry weight rank” method showed that the coastal zone was dominated by Panicum repens L. (45.46%), the embankment zone was dominated by Cynodon dactylon L. Pers. (30.28%), the rice-field zone was dominated by Cynodon dactylon L. Pers. (35.17%), and the residential zone was dominated by Cynodon dactylon L. Pers. (23.60%). The forage production in Mangunlegi village (except the embankment zone) was 793.64 ton of dry matter per year. This forage production could fulfill 345.68 livestock unit. However the forage production of embankment zone was 96.34 ton of dry matter per year. This forage production could fulfill 41.96 livestock unit. The value of increment capacity of ruminant livestock population (KPPTR) effectively showed that Mangunlegi village can hold the population up to 202.14 livestock units.

Judul: Analisis Potensi dan Pemanfaatan Hijauan Pakan pada Peternakan Domba Rakyat Desa Randobawa Ilir Kecamatan Mandirancan, Kabupaten Kuningan, Jawa Barat
Abstrak: Randobawa ilir is one of the villages in Kuningan Regency where found sheep breeding farm. The aim of this experiment was analyzing potential and utilitazion of forage on sheep breeding farm in Randobawa Ilir village as a feed of ruminant forage. This experiment used descriptive analysis, composition botany analysis, analysis of carrying capacity, and diversity analysis. The results of composition of botany showed that the first rank of forage was Eragrostis sp. as many as 14.01%, the second was Digitaria sp. as many as 9.96%, and the third was Mikania micrantha H.B.K. as many as 9.90%. The result of analysis of carrying capacity showed that Randobawa Ilir village still allowed for addition of livestock as many as 129.39 AU. The result of diversity analysis showed that diversity on paddy field higher than farm. The highest importance value on paddy field was Cynodon dactylon L. Pers. as many as 31.53% and the highest importance value on farm was Oplismenus burmannii (Retz.) P. Beauv as many as 68.64%.

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.
