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 dan Evaluasi Struktur Atas Tower C Grand Center Point Apartement Terhadap Beban Gempa Berdasarkan Peta Gempa Indonesia 2010
Abstrak: Indonesia is a very vulnerable country against earthquakes because of it is located between three active earth slabs like Pacific, Indo-Australian, and Eurasia. The number of volcanoes also make Indonesia become vulnerable too. The occurrence of strong earthquakes produce an energy that can shake everything on the Earth's surface, include tower building. The purpose of this research is to analyze and evaluate the resistance of Tower C Grand Center Point Apartment structure against earthquake load based on Indonesian Earthquake Hazard Map 2010 using static equivalent, respon spectrum and time history method. This research was done in March-June 2013 used secondary data like Shop drawing of Grand Center Point Apartment, then analyzed by ETABS 9.7.2, and Microsoft Excell. Steps in doing this research is collecting data, modeling, structure loading, structure analysis, and structure evaluation. The result of the analysis: the number of the structure reinforcement without earthquake load is larger than the number of the analyze reinforcement, so in this situation the structure is safe. On static earthquake condition with static equivalent analysis, some component still have so many unsafe structure because the existing reinforcement is smaller than the analyze reinforcement. On the dynamic condition, especially with respon spectrum analysis, the structure more weak to against earthquake load rather than on the static condition. This is caused by the structure component with its existing reinforcement which smaller than the analyze reinforcement is increase

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.
