Judul: Keanekaragaman Jenis Burung pada Beberapa Tipe Habitat di Pulau Ternate
Abstrak: Ternate Island is a small island that has not been studied intensively for it bird community. The objectives of this research were (1) to describe the habitat of birds, (2) to examine bird diversity, and (3) to examine guild composition. The research was conducted at five habitats (mix planting, coastal forest, lake area, residential area, and open spaces (OS)) in January- February 2012. A descriptive analysis was used to describe the habitat profile and guild, whilst bird diversity was analyzed using Shannon-Wienner diversity index and Jaccard index of similarity. A total of 51 bird species from 17 families was recorded. The highest diversity was in the lake area (H’= 2,56) and the lowest diversity was in OS (H’= 0,89). The highest similarity index was between residential area and OS (IS= 0,54). The most dominant guild was insectivores and the most dominant bird was Passer montanus. Recommended management implication are: (1) provide and maintain bird habitat, (2) planting a favourite vegetation for birds, (3) intensive monitoring, and (4) develop an environmental education programs.

Judul: Keanekaragaman jenis Burung pada beberapa tipe Habitat di Hutan Penelitian Dramaga, Bogor, Jawa Barat
Abstrak: Dramaga Research Forest, located in the outskirt of Bogor, provides a good habitat for birds. This research was aimed to study bird diversity, identifying habitat characteristics (around the forest path, along house edge, riparian habitat and the interior area) and recorded the activities of the local people around the forest. Point count, MacKinnon list, habitat profiling and interviews were conducted. Shannon-Wiener diversity indices and similarity level were calculated. The highest index of species diversity was in the interior area (2.34), followed by around the forest path (2.21), along house edge (1.97) and riparian habitat (1.86). The highest species richness, however, was in the riparian habitat (27 species), the forest path had 21 species, along house edge had 26 species, while the interior area was a home for 21 bird species. The highest similarity (0.81) was between forest path and interior area. On the activities of the local people, the most often was firewood harvesting. Other activities were hunting for cage birds, harvesting ferns, harvesting wild fruit and harvesting ant larvae. Activity that might disrupt the bird population was hunting.

Judul: Konversi Asam Stearat dan Asam Oleat Menjadi Senyawa Oksazolina dengan Katalis Zeolit Teraktivasi Berbantuan Gelombang Mikro.
Abstrak: Oksazolina adalah senyawa heterosiklik dengan R tertentu dapat digunakan sebagai antikorosi karena mempunyai kerapatan elektron yang tinggi sehingga dapat terabsorpsi kuat pada permukaan logam. Penelitian ini bertujuan menyintesis senyawa 2-heptadesil-4,5-dihidrooksazol dan (Z)-2-heptades-8-en-1- il-4,5-dihidrooksazol dengan melakukan konversi dari asam stearat dan asam oleat menggunakan aminoalkohol sebagai reagen dan zeolit teraktivasi sebagai katalis berbantuan gelombang mikro pada beragam daya. Daya optimum ialah 300 W. Rendemen yang diperoleh yaitu 55% untuk senyawa (Z)-2-heptades-8-en-1-il-4,5- dihidrooksazol dan 6,5% untuk senyawa 2-heptadesil-4,5-dihidrooksazol. Stuktur oksazolina dicirikan berdasarkan spektrum inframerah yang menghasilkan pita spektrum baru pada bilangan gelombang 1650 cm-1 dan 1044 cm-1, masingmasing untuk gugus fungsi imina dan eter, selanjutnya dicirikan dengan teknik resonansi magnetik inti.
