Abstrak: The purpose of this study is to develop a design special interest tourism (SIT) based on the pattern of movement, characteristic of activity sites and behavior patterns of the javan rhino (Rhinoceros sondaicus Desm, 1822) in Ujung Kulon National Park. Data collection was conducted from January until May 2012 in Citadahan, Cibandawoh, Cigenter and Nyawaan of Ujung Kulon Peninsula. Data on movement pattern was collected according to trajectory scheme. Activ sites was compiled from sample plot, while behavioral pattern was captured and identified from video trap data in 2011 and compiled into an ethogram. SIT aspect was acquaired by interview and quitionnare. Minimum outer convex polygon was used for home range calculation, and analysis binomial regression was used to determined characteristic of rhino activity sites while descriptive analysis was used to determined behavioral pattern and SIT design. Javan rhino movement patterns tend to use the same track regularly and create a polygonal pattern. Movement is influence by sex, age and availibity of ideal habitat. Male javan rhino has a larger home range than female, and home range of an independent female rhino is larger than females with calf. Characteristic of rhino activity sites are different between feeding, dung, wallowing and resting places. This research found that the javan rhino active mostly during the night, while wallowing is mainly during the day. Recomendation for SIT design base on javan rhino movement pattern are : a) observation bathing activities of javan rhino on the beach by camping, b) observation bathing activities in the river by canoeing, c) observation wallowing and/or bathing activities by using rangoon

Judul: Analisis Karakteristik Kubangan Badak Jawa (Rhinoceros sondaicus Desmarest 1822) Di Taman Nasional Ujung Kulon
Abstrak: Javan rhino (Rhinoceros sondaicus Desmarest 1822) is a rare and unique species. Today, its population can only be found in Ujung Kulon National Park. One of insitu conservation efforts to keep the population existence of javan rhino is creating the second habitat. The most important thing to conduct this program is to identify the behaviors of javan rhino. Wallowing is an important behavior of javan rhino. Based on javan rhino’s behavior, the characteristic of its wallow can be identified. The observed characteristics of wallow will determine the standard or criteria of habitat which will be used for selection strategy of further javan rhino’s wallow. The objective of this study was to identify the wallow characteristic of javan rhino both physical and biological factors and to identify the dominant ecological factor in determining wallow selection strategy for javan rhino. The results of this study is hopefully used for the consideration in determining the second habitat of javan rhino and for the basics information of habitat development of javan rhino insitu conservation. The data that were collected consisted of physical characteristic javan rhino’s wallow i.e. the length and the width of wallow, the depth of mud and water of wallow, water pH inside the wallow, the height of wallow site, the temperature and humidity, and the distance from wallow to the coastal, river, and from human access. The biotic characteristic aspects of javan rhino’ wallow that were observed consisted of the number of javan rhino’ feed and the total density of vegetation spread around the wallow according to result of vegetation analysis. The observation result shows that the dominant length of wallow was range from 3-4 meters and the width was range from 2-3 meters. The temperature was about 26-29°C with 67-90% of humidity, water pH of the wallow was normal (pH 7). The height of wallow site was < 100 m above sea level, and mostly found in 1354-2292 meters from the coastal, 702-1012 meters from the river, and 50-370 meters from human access. The total density of vegetation around the wallow was about 8750-53755 ind/ha for the seedling, 800-18607 ind/ha for the sapling, 25- 906 ind/ha for the poles, and 25-174 ind/ha for the tree. The location of 16th and 18th wallows consisted of highest number of feed, which were 35 species of plants. Based on the result of factor analysis, the dominant ecological factors of wallow selection are height of the site, air temperature, and tree density.

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%.
