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: Seismic Performance Evaluation of the Sabilulungan 99 Tower Structure in Bandung Regency using the Nonlinear Static Pushover Analysis Method
Abstrak: Salah satu wilayah dengan kerawanan gempa bumi yang tinggi adalah Pulau Jawa. Menara Sabilulungan 99 yang terletak di Kabupaten Bandung ini merupakan menara dengan struktur beton bertulang yang memiliki sistem rangka pemikul momen. Periode struktur yang dimiliki adalah sebesar 2,6 detik. Rasio partisipasi massa yang diperoleh mencapai nilai di atas 90% baik arah x dan arah y pada ragam getar ke 9. Gaya geser dasar yang diperoleh ketika titik performa tercapai dalam analisis pasca-elastik adalah sebesar 10402,90 kN untuk arah x dan 10178,88 kN untuk arah y. Perpindahan lateral atap pada arah x dan arah y masing-masing adalah sebesar 568,53 mm dan 602,51 mm ketika titik performa struktur tercapai. Berdasarkan parameter deformasi struktur pada acuan ATC 40 dan FEMA 356, tingkat kinerja struktur merupaka Life Safety (LS). Daktilitas yang dimiliki struktur pada arah x dan y masing-masing adalah sebesar 1,7 dan 2,4 sehingga struktur tergolong ke dalam daktilitas rendah pada arah x dan daktilitas sedang pada arah y., One of the regions with high earthquake vulnerability is Java Island. The Sabilulungan 99 Tower, located in Bandung Regency, is a tower with a reinforced concrete structure that features a moment-resisting frame system. The structure
