Judul: Parameter Demografi dan Penggunaan Ruang Vertikal Lutung Jawa (Trachypithecus auratus Geoffroy 1812) di Resort Tamanjaya Taman Nasional Ujung Kulon
Abstrak: Demography parameter of ebony leaf monkey at Tamanjaya Resort of Ujung Kulon National Park wasn’t knew. Demography parameter was important component to the studied of population. The purposed of this study was to estimated demography parameter and indentification of used spatial vertical. The method used of demography parameter was consentration count method. The continuous recording method used for the analysis of the used of space, and method used in the analysis vegetation was plot method. Result of the study showed there were 17 individual of 3 grups, with composision 5 childerns, 4 juvenliles, 3 adult males and 5 adult females. Sex ratio from 3 groups were 1:1.6. Birthrate were 0.29. The highest mortality occured from juvenile to adult was 0.66. Ebony leaf monkey in Tamanjaya Resort used B and C level.

Judul: Aktivitas harian dan wilayah jelajah Lutung Jawa (Trachypithecus auratus Raffles 1821) di Resort Bama Taman Nasional Baluran
Abstrak: Baluran National Park particuralry Bama Resort is one of Javan Ebony leaf monkey (T.auratus Raffles 1821) habitat. This research purposes were to study daily behavior and homerange of Ebony leaf monkey group. The observation was conducted using Focal animal sampling method, the observation target is the activity of each Ebony leaf monkey group recorded continuously. Homerange was recorded by tracking and following the Ebony leaf monkey group while mapped using GPS (Global Positioning System). The average active time between two groups was around 12 hours 12 minutes, activity percentage from highest to lowest were 40% of feeding activity, 26% of moving activity, 22% of resting activity, and 12% of social activity. Average homerange from group I was 7,46 ha and group II is 13,15 ha. Main foods for Ebony leaf monkey were contains of Asam Jawa, Kesambi, Mimbo, Pilang, Kepuh, Walikukun, Akasia, and Jerukan

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%.
