Judul: Teknik penangkaran dan aktivitas harian jalak bali (Leucopsar rotschildii Stresemann 1922) di penangkaran UD Anugrah Kediri Jawa Timur
Abstrak: Bali starling (Leucopsar rotschildii Stresemann 1922) is a popular species among people. Population of bali starling in the natural habitat had decreased due of hunting activities. It is necessary to the preservation through captive breeding. One important aspect is knowing bali starling activities, knowing activities from bali starling can monitoring health, diet and breeding. This research was aimed to study captivie breeding techniques, identify measures of success and observe the daily activities of the bali starling. The research was conducted in UD Anugrah located in Kediri East Java on June-July 2012. Instrument used include digital camera, stationery, tally sheet, interview guide, stopwatch, dry and wet thermometer and object of the research was bali starling and manager from UD Anugrah. The data of captive breeding techniques was analyzed descriptive, measures of success from UD Anugrah and daily activities were quantitative analysis. The kind of cage in UD Anugrah consisted of display cage, reproduction cage, solitary cage and incubator. Facilities provided in the cage were among other perch place and places to eat and drink. The cage was regularly cleaned once a day and sprayed with disinfectant once a month. Types of disease that had bali starling in UD Anugrah was diarrhea. Activity of captive breeding from UD Anugrah can be categorized success were reproduction level high (65%), moderate egg hatching rate (50%) and low mortality (25%). Socially also declared a success by involving the local community as a keeper and feed providers. There are 19 activities performed by bali starling in UD Anugrah. Type of activity that can be used to distinguish the sex of bali starling was nesting activity performed by female individual.

Judul: Teknik penangkaran dan analisis koefisien inbreeding pada jalak bali (Leucopsar rothschildi) di Mega Bird and Orchid Farm (MBOF), Bogor, Jawa Barat
Abstrak: Bali starling (Leucopsar rothschildi) is an endemic species of Bali Island which needed to be preserved. It’s population in the nature had decreased that the species stated as rare and endangered. It had been include in the criticaly endangered category of the Red Data Book and also included in the Appendix 1 CITES. The condition required conservation efforts. Captivity bread in ex-situ conservation. Was one of the effort to conserve bali starling. Mega Bird and Orchid Farm (MBOF) was one of the captive breeding effort which succeed in breeding bali starling. Calculation of inbreeding coefficient should be done forward bali starling bred in the farm in order to maintain it’s genetic purity. Morphological measurement should also be done to identify inbreeding pressure. Research was held in Mega Bird and Orchid Farm (MBOF) on June until October 2011. The data type used was consisted of primary and secondary data. The data of techniques captive breeding was analyzed descriptive and quantitative analysis, inbreeding coefficient was quantitative analysis. Analysis using t-student test was also employed in compary body size of female and male bali starling, The test was conducted using SPSS 16.0. Descriptive analysis was also conducted compary data of body size in this research with data in previous research and qualitative morfological characteristic of bali starling. Captive breeding of bali starling in MBOF began in 1996 with three pairs of bali Starling origineted from Safari Park I Cisarua Bogor, from the bird seller and the bird lovers. There were 91 individual of bali starling up to Oktober 2011. The kind of cage in MBOF consisted of display cage, maintenance cage, reproduction cage and incubator. The feed given to the bali Starling were banana, voer, crickets, and kroto (ant’s egg). The average number of highest consumption was crickets 15.18 g/tail/day and the palatability of 59.22 %. Each individual of bali starling in MBOF needed 11.48% protein and1909.0 kcal/day. Types of diseases that had attacted in the bali Starling MBOF were cataracts, smallpox on foot, flu (influenza) and sore eyes. Percentage and criteria captive breeding success of bali starling were high egg hatching rate (66.66%), moderate mortality (33.33%) and reproduction level high (63.88%) . The analysis of inbreeding coefficient should a result of 0 value, which ment that there was not any occurrence of inbreeding. However, there was a possibility of helf sibling marriage with inbreeding coefficient value of 0.25. There was not any significant different between quantitatif morphological characteristic of the male and female body size. There was any significant difference between the data of morfological characterstic current research the previous once conducted by Masy’ud (1992) and Helvoort et al. (1985) which ment that there had not been any inbreeding pressure to bali starling in MBOF.

Judul: Membran Komposit Kitosan-Zeolit untuk Aplikasi Direct Methanol Fuel Cell
Abstrak: Direct methanol fuel cell (DMFC) is a fuel cell that utilize methanol as the fuel source. The electrolyte membrane used in the DMFC system in this research was chitosan-zeolite composite membrane. The composite membrane was synthesized with chitosan-zeolite composition variation of 1:1, 1:2, 1:3, and 2:1. The membranes were analyzed by Fourier transform infrared spectrophotometer (FTIR) and scanning electron microscope, and for the specific gravity. Membrane performances were tested with methanol uptake, methanol permeability, conductivity, and potential difference in the DMFC system. The FTIR spectrum showed no formation of new functional groups inducating that the composite membrane was a result of physical mixing. Morphological analysis showed that the membrane was nonporous. Chitosan-zeolite 1:3 composite membrane had the highest specific gravity and methanol uptake, 1.4226 g/mL and 41.44%, respectively. The highest proton conductivity was showed by the 1:2 chitosanzeolite composite membrane, namely 7.2946× 10-7 S/cm. Based on this research results, chitosan-zeolite composite membrane can be applied in DMFC system.
