Judul: Pemeliharaan dan Pengembangbiakan Kupu-Kupu Papilio memnon Sebagai Upaya Persiapan Taman Kupu-Kupu di Plaza Institut Pertanian Bogor
Abstrak: Two domes at Bogor Agricultural University (BAU) plaza are so potential to create a butterfly garden that ecoeduturisme in campus can be complete. Therefore, a study is needed to before creating the butterfly garden and in managing it. This research is aimed to rear and culture P. memnon butterfly in order to prepare and manage the butterfly garden at plaza BAU. The parameters observed in this research included life cycle, life expectancy, sex ratio, synchronization of imago emergence, and abiotic factors. Rearing activity was a combination method in laboratory and dome Plaza BAU. Life cycle of F1 ranged between 30 and 80 days while F2 ranged between 40 and 101 days. Survivorship curve indicated that the mortality started to increase at the fifth instar larvae. Differences in imago emergence periode have caused difficulties for the butterfly pairs to do mating and they were finally died. Plants for feed and nectar sources must be provided to sustain butterfly garden. Internal and external barriers must be intensively controlled so ecoeduturisme function of butterfly garden can be realized.

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.
