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: Upaya peningkatan harapan hidup Kupu-kupu Papilio demoleus dari telur hingga imago dengan sistem penangkaran
Abstrak: Utilization of butterflies are often not balanced with maintaining sustainability in nature. Captive breeding is done as an effort to cultivation the plant and wildlife with maintain the purity of the strain. One species of butterfly that can be used is P.demoleus. Establishment the garden of butterfly for ecoedutourism object in Bogor Agricultural University (BAU), is a manifestation of utilizing the butterflies. Increase the life expectancy of a butterfly and be expected to have produced a big population without nature destructive. Captive breeding system was combined with laboratory treatment to increase the life expectancy of a butterfly until imago phase. The process of spawning be located at the dome and treatments performed in the laboratory with observed the imago copulation, life cycle, life expectancy, metamorphosis of P.demoleus, sex ratio, and abiotic factors. Mostly,life cycle of P.demoleus F1 is 34.11 ± 2.70days (29-40 days) and a F2 life cycle is longer 39.07 ± 3.30 days (33-45 days). Survival curve type I, high mortality rate was occurs in adult stage. At the pupa’s phase in the amount of 33.33 percent is the highest mortality. Many deaths in each phase due to parasites, bacteria, and eclosion failure. P.demoleus butterfly life expectancy increased to 44.60 percent from his life expectancy that is 2 percent in the wild. Research about captive breeding system effectivity and renovation of the dome facilities, is support the realization of a butterfly garden at the BAU.

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.
