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.

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: Analisis struktur kristal kalsit (CaC3) dengan metode rietyeld
Abstrak: Telah dilakukan analisis data XRD pada suhu ruang dengan penghalusan parameter metode Rietveld pada bahan kalsit (CaCO3). Dihasilkan nilai indikator R-pola (Rp) 10,43%; R-pola dengan pemberat (Rw) 15, 35%; R-Bragg (Ra) - 3,94%; penyesuaian terbaik (GoF) 3,49 dan faktor Durbin-Watson (d) 0,642. Dalam analisis ini diperoleh 21 parameter yang diperhalus mencakup latar belakang (6), faktor skala (1), pergeseran titik nol (1), bentuk puncak U,V,W (3), koefisien puncak FWHM (3), ocupancy (6) dan arah orientasi yang disukai (1). Hasil analisis juga menunjukkan bahwa struktur kristal kalsit adalah heksagonal dengan parameter kisi hasil penghalusan adalah a=b=4,9891 A, c- 17,0424 A, a-B-90 dan y120"
