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

Judul: Evaluasi Kinerja Struktur Gedung Bertingkat di Jakarta Menggunakan Pushover Analysis
Abstrak: Gempa bumi menjadi bencana yang sering terjadi di Indonesia. Gempa bumi menyebabkan bangunan bergeser dan jika nilai geser ultimate melebihi nilai beban geser nominal akan membuat struktur mengalami keruntuhan. Evaluasi struktur diperlukan untuk mengetahui tingkat kinerja struktur gedung eksisting terhadap gempa. ASCE 41-17 mengatur cara evaluasi seismik dan retrofit bangunan eksisting pragempa menggunakan prosedur non static liniear. Hasil evaluasi menunjukkan bahwa gedung bertingkat masih mampu menahan gaya gempa BSE 1E dan BSE-2E serta masih memiliki kekuatan untuk menahan gaya gempa sampai perpindahan target awal. Hasil simpangan yang dihasilkan memiliki nilai dibawah batas izin untuk arah X dan Y pada level gempa BSE-1E sebesar 202,504 mm, 196,176 mm dan BSE-2E sebesar 274,352 mm, 266,56 mm. Sendi plastis terbentuk pertama kali pada elemen balok selanjutnya pada kolom. Tingkat kinerja struktur gedung untuk gempa BSE-1E berada pada level immediate occupancy dan gempa BSE-2E berada pada level damage control. Rasio daktilitas struktur memiliki nilai daktilitas parsial dengan nilai demand capacity ratio yang memenuhi sehingga tidak diperlukan retrofit., Earthquakes are a frequent disaster in Indonesia. Earthquakes cause buildings to shift and if the ultimate shear value exceeds the nominal shear load value, the structure will collapse. Structural evaluation is required to determine the level of performance of existing building structures against earthquakes. ASCE 41-17 regulates the seismic evaluation and retrofitting of pre-earthquake existing buildings using the non static linear procedure. The evaluation results show that the building is still able to withstand BSE-1E and BSE-2E earthquake forces and still has the strength to withstand earthquake forces up to the initial target displacement. The resulting deformations have values below the permissible limits for the X and Y directions at the BSE-1E earthquake levels of 202.504 mm, 196.176 mm and BSE-2E of 274.352 mm, 266.56 mm. Plastic joints formed in the beam elements first and then in the columns. The performance level of the building structure for the BSE-1E earthquake is at the immediate occupancy level and the BSE-2E earthquake is at the damage control level. The ductility ratio of the structure has a partial ductility value with a demand capacity ratio value that meets the requirement so that no retrofit is required.

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.
