Judul: Inventarisasi dan kajian potensi invasif Arthropoda dan tumbuhan yang masuk ke wilayah Indonesia melalui Bandara Soekarno-Hatta dan Pelabuhan Tanjung Priok:
Abstrak: Peningkatan mobilitas manusia dan barang menimbulkan peningkatan kemungkinan lalu lintas organisme di seluruh dunia. Organisme yang dilalulintaskan tersehut antara lain ternak, binatang piaraan, bibit, dan produkproduk pertanian serta kehutanan yang banyak dimasukkan ke suatu negara dari negara lain untuk berbagai tujuan. Pemasukan tersebut merupakan pemasukan yang disengaja. Selain pemasukan secara sengaja, organisme juga dapat masuk ke suatu negara secara tidak sengaja, misalnya dengan mengkontaminasi komoditas yang dimasukkan secara sengaja. Organisme yang masuk secara sengaja maupun tidak sengaja perlu diwaspadai karena kemungkinan dapat menimbulkan permasalahan di kemudian hari. Permasalahan yang dapat timbul di kemudian hari salah satunya disebabkan oleh kemampuan organisme tersebut untuk bertahan dan berkembang biak serta pada akhirnya mengancam keanekaragaman hayati. Permasalahan ini dapat ditimbulkan oleh spesies asing invasif atau dikenal dengan Invasive Alien Species (IAS).

Judul: Study Invasive Alien Insects and Plants Species in Indonesia.
Abstrak: Agricultural Quarantine Agency (AQA) is developing a duty to prevent the entry and spread of invasive alien species in Indonesia. This study was conducted to analyze the potency of alien species listed in quarantine pests, introduction intentionally through import, and introduction unintentionally through contamination of imports plant products to become invasive and quarantine pest, its revenue through import intentionally, and unintentionally income through contamination of plant products imports. This is done to make an inventory of invasive alien species, to know the character of invasive and existence in Indonesia. This study has focus on the species of insects and plants. Data were obtained from the inventory insects and plants listed as quarantine pests, sampling of imported agricultural and forestry products such as seed or non-seed to detect and identify contaminant species, the results AQA interception in 2010-2011, collection of interception at Agricultural Quarantine of Tanjung Priok Sea Port and Soekarno Hatta Air Port, as well as survey of plants to the nursery in Jabodetabek and Karawang. In addition, the data of imported living plants, seeds and non-seeds in 2010-2011 BARANTAN were also analyzed. All data were compared to the list of invasive species in Global Invasive Species Database (GISD). The dentified that were listed in GISD were classified as invasive species, and then were studied their bioecology, historical invasion, and impact. Species that are not included in the list of GISD performed invasive potential of information retrieval. The results showed that 12 species of insects and 3 species of weeds listed in the quarantine pests could be classified as invasive species. Five species as contaminants of imported products were invasive insect species and 37 were found plants. The invasive insects Agrilus sulcicollis and Megacyllene robiniae not exist in Indonesia and are not listed in the quarantine pests and GISD. Five of invasive plants which are not exist in Indonesia were Cirsium vulgare, Cirsium arvense (quarantine pest A1 category), Centaurea melitensis, Lepidium virginicum, and Melilotus albus. Introduction invasive alien plants were imported and the results of survey there are 18 invasive plants species of GISD. One of 18 plants species is known as quarantine pest A2 category (Asystasia gangetica subsp. micrantha). The invasive alien species that do not exist in Indonesia can be used as target material monitoring and revision is a list quarantine pest. Management of invasive species in the pre-border needs to be improved by making the target invasive species inspection, increased expertise of identification, improvement of the quality standards of imported products, and the acceptance of the application of Sanitary and Phytosanitary Measures as well as.

Judul: Sintesis α-Fe2O3 menggunakan metode sol gel
Abstrak: In this reseach was succeeded make powder α-Fe2O3 with particle size 202.64 nm. Synthesis using Sol-Gel method with SiO2 coating derived from Si(OC2H5)4 at temperature of 750 oC for 5 hours. Characterization XRD prove that sample form is α-Fe2O3 (11 peaks) and β-Fe2O3 (2 peaks) with crystal size 20.69125 nm and crystallization 44 %. The cystal structure of α-Fe2O3 is rhombohedral and β-Fe2O3 is hexsagonal. Optic characterization show that the sample absorbing light at wavelength less than 480 nm. Bandgap energy of the optical characterization measurments is 2.74 eV.
