Judul: Bird Diversity on Several Type of Habitat in Lore Lindu National Park, Central Sulawesi Province
Abstrak: Lore Lindu National Park (LLNP) is located in Central Sulawesi included to Wallacea. LLNP is a habitat for 80% Sulawesi endemic bird, those bird species are sulawesi dwarf hornbill, large sulawesi hanging parrot, and maleo. Preasure that happen surround the habitat in LLNP become bigger such as land withdrawal by people and using it as a road to their coffe and chocolate plantation, and rice fields. Land withdrawal causing a change of forest structure and composition, and make a change on animal diversity in bird particulary. The differentiation of habitat condition make a bird diversity difference. However, data and fact is not complete and have interest to study.

Judul: Sebaran Keanekaragaman Spesies Reptile pada Beberapa Tipe Habitat di Taman Nasional Lore Lindu
Abstrak: Indonesian biodiversity facing a serious challenge in terms of identification of species contained therein. The conservation of species cannot be separated from the ecosystem. Lore Lindu National Park is a representative of humid tropical forest ecosystem types with high biodiversity inside. Including the diversity of reptiles species. Diversity of reptiles species and it is distribution pattern is studied in this research. The study was conducted in June-August 2008 in Lore Lindu National Park. The research site area inside the park is in Resort Lindu and Resort Mataue. Materials used in this study is the type species of reptiles and their habitats as well as alcohol. The equipment used is standard equipment for collecting reptiles species data using visual encounter survey method. Including RBI map sheet 2114-41 and 2014-62, reptiles observation equipment, documentation equipment, GPS receivers, stationery, and computer hardware and software. Reptiles data collection based on visual encounter survey method. Habitats vegetation analysis based on quadrats transect line described by Oasting (1948). Only captured or documented reptil species that can be identified which entered into the list of species found. Reptiles species data observation using active searching reptiles specimen and glue trap. The result, 17 reptiles species can be identified from the research area. Six species distributed inside plantation habitat type, eleven species inside the transitions areas habitat type, and seven species inside the forest. Transitions areas habitat type form the highest reptiles species richness. Shown by species list and Margalef’s index. But there inside Eutropis multifasciatus dominating significantly. Forest habitat type is the highest reptiles species diversity value shown by Shannon-Wiener Index. Although the number of reptiles species distributed there in less than transition areas, the reptiles species distributed more evenly.

Judul: Katalis Zink Ferit Tersubstitusi Cu untuk Oksidasi Benzil Alkohol
Abstrak: Katalis berperan dalam menurunkan energi aktivasi. Katalis ZnFe2O4 dan ZnFe2O4 tersubstitusi Cu disintesis menggunakan metode kopresipitasi untuk digunakan dalam oksidasi benzil alkohol. Katalis dicirikan dengan spektrofotometer inframerah (FTIR) dan difraktometer sinar-X. Spektrum FTIR menunjukkan puncak serapan dari ikatan Zn-O dan Fe-O masing-masing pada rentang 559‒575 cm-1 dan 419‒447 cm-1. Difraktogram menunjukkan terbentuknya fase tunggal Zn0.6Cu0.4Fe2O4 pada katalis ZnFe2O4 tersubstitusi Cu 20%. Benzil alkohol dioksidasi dengan sistem refluks. Konversi benzil alkohol meningkat dengan meningkatnya suhu. Kadar benzaldehida yang dihasilkan dengan katalis ZnFe2O4 tersubstitusi Cu 20% lebih tinggi dibandingkan dengan katalis ZnFe2O4 yang tidak tersubstitusi dan yang tersubstitusi Cu 60 dan 80%. Hal tersebut menunjukkan bahwa katalis ZnFe2O4 tersubstitusi Cu 20% memiliki kinerja yang lebih baik dalam oksidasi benzil alkohol menjadi benzaldehida dengan kadar benzaldehida 8.763%.
