Judul: Analisis Struktur Portal 3D Simetris dan Tidak Simetris terhadap Beban Gempa Kuat
Abstrak: Safe and convenient house design from all hazards is indispensable, nonetheless including the earthquake disaster to minimize its impact. The purpose of this research is to design the frame structure 3D symmetrical and not symmetrical and compare his strength with respect to the burden of strong earthquake based on SNI 03-2847-2002 and SNI 03-1726-2003. Research methods to be performed consists of several stages, namely a study library, creation of the frame structure 3D symmetrical and not symmetrical using SAP 2000 program version 14, making the spektrum of earthquake based on seismic hazard map of Indonesia 2010, and testing the structure against strong earthquake loads using SAP 2000 program version 2. Research results is the frame structure 3D symmetrical and not symmetrical 2 floor, wide 8 m, long 10.5 m, the dimensions of a column of 0.5 m x 0.5 m, the dimensions of a beam 0.45 m x 0.3 m, for all loads combination, the value of shear structure, reaction force, and concrete reinforcement of the frame structure 3D not symmetrical is greater than the frame structure 3D symmetrical.

Judul: Analisis Kekuatan Struktur Pada Bangunan 8 Lantai Berdasarkan Respon Spektrum SNI 03-1726-2019 Menggunakan SAP2000
Abstrak: Suatu struktur bangunan gedung atas beberapa elemen penyusun strukturnya. Indonesia merupakan daerah rawan gempa karena dilalui oleh jalur pertemuan 3 lempeng tektonik. Upaya mitigasi kegagalan struktur di Indonesia akibat gempa sangat perlu dilakukan untuk mengetahui kondisi kinerja struktur bangunan tersebut. Tujuan penelitian ini adalah untuk melakukan pemodelan menggunakan software SAP2000 serta menganalisis kekuatan struktur pada bangunan 8 lantai terhadap gempa. Penelitian dilakukan dengan menggunakan tiga skenario dengan metode respon spektrum. Penyesuaian as built drawing perlu dilakukan karena terdapat perbedaan antara gambar rencana dengan kondisi existing. Pada hasil identifikasi kegagalan struktur Gedung X terdapat kegagalan pada saat beban gempa diinputkan. Terdapat 2 frames yang mengalami overstress pada skenario tiga. Berdasarkan hasil analisis simpangan antar lantai dan efek P-Δ, Gedung X dinilai aman karena nilai yang didapat tidak melebihi simpangan izin. Rekomendasi struktur berupa penambahan dimensi kolom menjadi 500 mm × 500 mm, serta pembesaran diameter tulangan menjadi 32 mm., A building structure consists of several structural elements. Indonesia is an earthquake-prone area because it is traversed by the meeting point of 3 tectonic plates. Mitigation of structural failures in Indonesia due to earthquakes really needs to be done to determine the performance conditions of these building structures. The purpose of this research is to perform modeling using SAP2000 software and to analyze the structural strength of an 8-storey building against earthquakes. The research was conducted using three scenarios with the response spectrum method. Adjustments to the as built drawings need to be made because there are differences between the plans and the existing conditions. In the identification results of the failure of the X Building structure there is a failure when the earthquake load is input. There are 2 frames that experience overstress in scenario three. Based on the analysis of the deviation between floors and the P-Δ effect, Building X is considered safe because the value obtained does not exceed the permit deviation. Structural recommendations include adding column dimensions to 500 mm × 500 mm, and increasing the reinforcement diameter to 32 mm.

Judul: Prevalence of Bird Lice on Rock Pigeon (Columba livia) in 99Wonderland Park, Selangor, Malaysia
Abstrak: Rock Pigeon (Columba livia) have coexisted with humans for thousands of years and are used for various purposes such as food and in sports. Rock pigeons may have the potential to be infested with a wide range of ectoparasites, which can have a significant impact on their life cycle. This study aims to measure the prevalence of Columba livia with bird lice in 99Wonderland Park, Selangor, Malaysia in the year 2020 and to ascertain the impact of bird lice on the health of these infested birds. Data were collected from clinical records for the month of January to December in the year 2020 from 99Wonderland Park, Selangor, Malaysia. Lice were identified in 42 of the 80 Rock pigeons examined so, the overall prevalence of lice infestations was 52.5%. The prevalence of ectoparasites was found to be higher in young Rock pigeons (60.4%) as compared to adult Rock pigeons (37.4%). Columbicola columbae (wing lice) and Colpocephalum turbinatum (body lice) are two species of lice that have been detected. Body lice were more prevalent in young Columba livia birds at 47.6% whereas wing lice were more prevalent in adult Columba livia birds at 16.7%. Most of the lice were found in the thorax and abdomen area followed by the head and neck area., Merpati Batu (Columba livia) telah hidup berdampingan dengan manusia selama ribuan tahun dan digunakan untuk berbagai keperluan seperti makanan dan olahraga. Merpati batu dapat terinfestasi dengan berbagai ektoparasit, yang dapat berdampak signifikan pada siklus hidup mereka. Penelitian ini bertujuan untuk mengetahui prevalensi Columba livia dengan kutu burung di 99 Wonderland Park, Selangor, Malaysia pada tahun 2020 dan untuk memastikan dampaknya terhadap kesehatan burung yang terinfestasi. Data dikumpulkan dari catatan klinis dari bulan Januari hingga Desember tahun 2020 dari 99Wonderland Park, Selangor, Malaysia. Kutu diidentifikasi pada 42 dari 80 merpati batu yang diperiksa sehingga, prevalensi keseluruhan infestasi kutu adalah 52,5%. Prevalensi ektoparasit ditemukan lebih tinggi pada merpati batu muda (60,4%) dibandingkan dengan merpati batu dewasa (37,4%). Columbicola columbae (kutu sayap) dan Colpocephalum turbinatum (kutu badan) adalah dua spesies kutu yang telah ditemukan. Kutu badan lebih banyak ditemukan pada burung Columba livia muda sebesar 47,6% sedangkan kutu sayap lebih banyak ditemukan pada burung Columba livia dewasa sebesar 16,7%. Sebagian besar kutu ditemukan di daerah dada dan abdomen diikuti daerah kepala dan leher.
