Judul: Design of Butterflies Breeding Business on IPB Dramaga Campus.
Abstrak: The butterfly is an animal that has many benefits, both in terms of beauty, craftproducts produced, as well as an object of tourist attraction. If managed well through breeding, all these benefits can be obtained, not only economic value, the success of a breeding butterflies will indirectly reduce the pressure on these animals in the wild. This study aims to analyze, create tread design and management, and analyze the financial feasibility of the butterfly breeding efforts. This research was conducted at the Campus IPB Dramaga for five months from July to November 2012, as the supporting data observed in Cilember Captivity Butterfly Bogor, Cihanjuang Butterfly Breeding Bandung, and Bali Butterflies Breeding. The method used in data collection include interviews, library research, and direct observations. Before designing the site and its management to prior breeding site suitability analysis, including the analysis of temperature, sunlight, rainfall and humidity, water, vegetation feed, and the presence of predators. Results of analysis of a number of environmental factors in the location of these observations indicate IPB Campus Dramaga suitable to serve as the location of butterflies breeding. The design of the site was made with three zoning, office Zones (0.37 ha), breeding (1.75 ha), and tourism (2.13 ha). Calculation results indicate that the captive power capacity capable of producing feed crops 11 138.27 gr to accommodate 924 individual butterflies per one production cycle. Sustainable harvest plan drawn up covering 60% of the crop is released into the butterfly enclosure as the main attraction, 28.1% is sold in the form of dead specimens (handicraft products), 10% restocking activities and remaining 1.9% will be used as seed. The results of the financial analysis indicates that butterflies breeding Campus IPB Dramaga feasible to run. NPV, BCR and IRR is the interest rate of 5% respectively is Rp 220 322 880, 1.64, and 31.35 %, whereas when viewed from the sensitivity analysis, a butterfly breeding business can survive up to 14% inflation rate.

Judul: Pengelolaan penangkaran kupu-kupu di PT Ikas Amboina dan Bali Butterfly Park Tabanan Bali
Abstrak: This study aims to determine and analyze the management of the breeding success rate of butterflies in PT Ikas Amboina and the Bali Butterfly Park. It is expected that this research can be an input for the PT Ikas Amboina and the Bali Butterfly Park itself in order to develop cultivation techniques and theutilization of butterflies better yet ,in addition this research also to expected to serve as guidelines for the management and or development of captive breeding butterfly elsewhere in Indonesia. This research was conducted through five stages namely study literature, measurements, observations, and interviews, as well as qualitative data processing. From the research result shows there are 15 species of butterflies that captived, consisting of two families namely Papilionidae and Nymphalidae. Two species of family Papilionidae including a protected butterfly, Ornithoptera priamus and Troides helena. There are five types of cages used during the captive process of butterflies, among other reproductive cage, cage rearing the eggs, the larval rearing, cocoon cage, and cage of butterflies. Plants used in the process of cultivating a butterfly on the basis of its functions can be divided into three, namely feed the larvae, the main plant (nectar-producing), and supporting plants (ornamental). Management conducted in captivity include the procurement of seed, maintenance of egg, larval rearing, maintenance pupa, maintenance of adult butterfly, health care, provision of additional food, and utilization of butterflies through activities of captive offset creation. Butterfly farming techniques are carried out intensively by PT Ikas Amboina able to increase the odds of living butterflies, which average 53.17% of the total eggs produced.

Judul: Karakteristik Carboxymethyl Chitosan Dengan Variasi Konsentrasi NaOH
Abstrak: Carboxymethyl chitosan is chitosan derivative product obtained from chemical modification. CMCh were made by alkalization process and carboxymethylation process. Factors that affect CMCh characteristics were excess sodium hydroxide in alkalization process, ratio between chitosan and monochloroacetic acid, and carboxymethylation temperature. The objectives of this research were to study the NaOH effect to CMCh characteristics, to learn process of making CMCh, to set the proper concentration of NaOH, and to analyze CMCh characteristics. CMCh yields were 110.72%-114.22%. CMCh pH value were 3.74-4.31. The optimum NaOH concentration to obtain the best CHCh was 10 M. Percentage of CMCh moisture content was 10.70%-11.42%. Ash content and nitrogen content of CMCh were 0.49%-0.50% and 4.52%-4.81%. CMCh viscousity was 8.25 cps. Percentage of CMCh solubility was 61.61%-91.50%. The different functional groups from chitosan which observed in CMCh were C=O group, CH group from alkene functional group, C−O group, and C−O−C group.
