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: 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: 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"
