Antiproliferative activity test of octadeca-8,10,12-triynoic acid isolated from parasitic plant scurrula atropurpurea (BI) dans. Againta four kinds of human cancer cell lines, i.e: HeLa (human cervix epitheloid carcinoma, leukemia THPI, (human peripheral blood acute monocyte), carcinoma a549 (human lung carcinoma) and lymphoma HUT78 (human cutaneous T-cell lymphoma) was carried out. The result showed that octadeca-8,10,12-triynoic acid exhibits the antiproliferative activity against four kinds of human cancer cell lines with the LC value of 0.66, 0.86, 0.99 and 2.36 mg/ml for HeLa, leukemia THPI, lung carcinoma a549, and lymphoma HUT78, respectively, lower than 4 mg/ml, which is the antiproliferative activity threshold for pure isolate or compound.

Study on diversity and distribution of insects was conducted in seven small islands of Karimunjawa Nationanal Park, Central Java from March 24 to April 7,2006, using two collection methods i.e pitfall traps and sweeping nets. The study collected 108 species of insect from the seven small island included 9 ordo of 44 families. They were Lepidoptera (27 species), Odonata (7species), Orthoptera (8species), Mantodea (2species), Blattodea (9species), Hymenoptera (20 species), Diptera (8species), Coleoptera (12species) and Hemiptera (15 species). The highest number of species was collected from Karimunjawa Island (96species), while other island were low: Genting (30species), kumbang (23species), kembar (26species), Nyamuk (56species), parang (50species), and bengkuang (23species). Base on fuction on nature, these insect could be divided into phytophagous, pollinator, decomposer, pasitoid, vector and unknown. Three species of butterflies were rediscovered during this study - they were euploea crameri karimondjawensis, euploea sylvester karimondjawana and idea leuconoee karimondjawana, while one species neptis columelle karimondjawae has not been found yet. Shannon, Simpson's and Alpha indexes, and similarity of jackard to compare the difference among the islands is disccussed.

Mangrove is an essential natural resources and vital component for coastal areas both ecology and socio-economic. Adapted mangrove vegetarian on tsunami disaster is important information for mangrove rehabilitation post-tsunami. The aim of the research was to determine the structure and species richness of mangrove vegetation post-tsunami in Aceh and Nias Island by vegetation analyses and inventory methods. Field survey was carried out in March 2005 - three months after tsunami disaster. We found 20 adapted mangrove species post-tsunami in Nias Island, dominated by rhizophora apiculata. Land system of KJP was compound of 17 adapted mangrove species, and land system of PTG and KHY were each compound of 7 adapted mangrove species. Based on our research, we recommended that R. apiculata is the first priority species to be used for mangrove rehabilitation in Nias Island
