Judul: A Study in Ecology, Population and Craniometry Bange (Macaca tonkeana) at Morowali Districk Central Sulawesi
Abstrak: Habitat destruction includes forest transformation and illegal logging and is the main factor for population decrease. The aims of this research were to evaluate the habitat conditions concerning group size, ratio of male to female, population density, vegetation stratum utilization and vegetation that has been frequently visited by monkeys; interaction between human population, Bange and forest; and craniometry of Bange. Methods used were line transect for population, diagram of habitat profile, Instantaneous sampling for food resources, interview for interaction between human population and forest and craniometry measurement for skull. Results showed that the population size was 39,82 individuals, density was 0,71 individuals/km2, ratio of male to female was 1:1,65. They used stratum B frequently (62,5%). Result of interview showed that agricultural disturbiance were caused by wild rats (44,80%), monkeys (29,90%) and wild pig s (22,30%). Total variability of skull size was 70,7% or higher than total variability of skull is length jowbone to the equal shape 0,498. Eigen vector value of each size and shape were 102,89 and 35,45. Cranial size of males Bange reality bigger than is female, but the have the same form.

Judul: Pendugaan Parameter Demografi Monyet Ekor Panjang (Macaca fascicularis Raffles 1821) di Situ Sangiang Taman Nasional Gunung Ciremai.
Abstrak: Long-tailed macaque (Macaca fascicularis Raffles 1821) have wide use in biomedical research hence being exported to many countries, such as China and U.S.A. Indonesia is one of many countries that export long-tailed macaque. Even so, they often have conflict with humans. Situ Sangiang which is located at Sangiang Resort in Taman Nasional Gunung Ciremai (Mt. Ciremai National Park) is one of many habitats of long-tailed macaque. This research aims to discover demographical parameters of long-tailed macaque at Situ Sangiang, which are population size, birth rate, mortality rate, sex ratio, and age structure. This research was held at 3-12 March 2015 using concentration count method towards three groups of long-tailed macaque. The data collected from the site indicated that population of long-tailed macaque at Situ Sangiang is 76 individuals with an average size of 25.33 ± 8,40 individuals per group. Sex ratio in the groups are 1:1.4 for makam group, 1:1.5 for cideres group, and 1:1.2 for ranca group with progressive population structure that will ensure the prosperity of long tailedmacaque population.

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%.
