Judul: Penangkaran Kupu Pachliopta aristolochia (Papilionidae: Lepidoptera) di Screen House dan Laboratorium
Abstrak: This study aims to domesticate of Pachliopta aristolochia in screen house and laboratory. Sixty-seven P. aristolochiae were released into the screen house. From six pairs mated butterflies produced two hundred and sixty eggs layed. Forty eggs were studied in the research. Twenty larvae were maintained in screen house and the other twenty larvae were maintained in the laboratory. Twenty larvae that developed into pupa in the screen house, were moved into the laboratory. The other twenty larvae were maintained in the laboratory. The twenty larvae in the screen house turned into a pupa and only nineteen butterflies were in normal condition, with sex ratio 8/11. Larvae in the laboratory developed into twenty normal pupas and produced fifteen normal butterflies with a sex ratio 11/4. All butterflies in the screen house can continue to develop and reproduce as long as Aristolochia tagala as larvae food and nectar of flower as butterfly food are available. The life cyle of P. aristolochiae in screen house from egg until pupa was 35,9±6,76 days.

Judul: Serangga parasitoid pada pupa Troides helena Linnaeus dan Papilio aristolochiae Linnaeus (Lepidoptera : Papilionidae) dari penangkaran kupu Cicurug, Sukabumi
Abstrak: Untuk mendapatkan parasitoid, pupa kupu raja Troides helena dan kupu ekor panjang Papilio aristolochiae telah dikoleksi dari penangkaran kupu Cicurug, Sukabumi dari bulan April sampai November 2001. Pupa-pupa tersebut di pelihara clalam botol pemeliharaan sampai keluar parasitoid. Tiga jenis parasitoid telah dipertelakan dalam 3 famili, yaitu Brachymeria /asus (Hymenoptera: Chalcididae), Xanthopimpla sp. (Hymenoptera: Ichneumonidae), dan Megaselia sp. (Diptera: Phoridae). B. /asus dan Xanthopimpla sp. memarasit P. aristolochiae sedangkan Megaselia sp. memarasit Troides helena. Dokumentasi dilakukan pada tiap jenis parasitoid meliputi jwnlah individu parasitoid yang keluar dari inang tunggal, persentase inang terparasit, dan kondisi pupa yang terparasit., To breed parasitoids, pupae of the common birdwings froides helena and common rose Papilio aristolochiae were regularly sampled from April to November 2001 from Cicurug butterfly farms, Sukabumi Those pupae were reared in rearing bottle until the parasitoids emerged. Three parasitoids were recorded belonging to three families, i.e. Brachymeria lasus (Hymenoptera: Chalcididae), Xanthopimpla sp. (Hymenoptera: Ichneumonidae), and Megaselia sp. (Diptera: Phoridae). B. lasus dan Xanthopimpia sp. parasitized on P. aristolochiae, whereas Megaselia sp. parasitized on Troides helena. Illustration were presented for each parasitoid spesies, including the number of individual parasitoids which emerged from single host, the percentage of the parasitized hosts, and the condition of the parasitized pupae.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
