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: Quail Blood Cholesterol Levels (Coturnix coturnix Japonica) On Starters, Growers and Layers phase
Abstrak: Cholesterol is one of fat formation components which is also the main sterol in animal tissues. Therefore its presence are contributing to development and growth of the body. This study aimed to determine blood cholesterol levels and body weight of quail in the starter,grower and layer phases, which were taken at the age of 18 days, 25 days and 330 days. The quail (Coturnix coturnix Japonica) used were ten tails of the starter phase, grower phase and layer phase. Blood cholesterol levels were measured using a NESCO MultiCheck 3 in 1 tool and body weight was calculated using a digital scale. Cholesterol levels decreased from the starter (158,40 mg/dL) phase to the grower phase (123,00 mg/dL) and increased again in the layer phase (219,6 mg/dL). The highest blood cholesterol value was obtained in the layer phase. The body weight over time continued to experience an increase and the increase in body weight from the starter to the layer phase was not followed by an increase in cholesterol levels. Cholesterol levels are used according to their physiological needs, Kolesterol merupakan salah satu komponen pembentuk lemak yang juga merupakan sterol utama dalam jaringan hewan, oleh karena itu kehadirannya memberikan kontribusi untuk perkembangan dan pertumbuhan tubuh. Penelitian ini bertujuan untuk mengetahui kadar kolesterol darah dan bobot badan burung puyuh pada fase starter, grower dan layer, yang diambil pada umur 18 hari, 25 hari dan 330 hari. Burung puyuh (Coturnix coturnix Japonica) yang digunakan sebanyak sepuluh ekor pada masing-masing fase starter, fase grower dan fase layer. Kadar kolesterol darah diukur menggunakan alat NESCO MultiCheck 3 in 1 dan berat badan dihitung menggunakan timbangan digital. Kadar kolesterol menurun dari fase starter (158,40 mg/dL) ke fase grower(123,00 mg/dL) dan meningkat lagi pada fase layer(219,6 mg/dL). Nilai kolesterol darah tertinggi diperoleh pada fase layer. Bobot badan dari waktu ke waktu terus mengalami peningkatan yang dan peningkatan bobot badan dari fase starter ke fase layer tidak diikuti dengan peningkatan kadar kolesterol yang artinya bobot badan tidak berpengaruh pada kadar kolesterol burung puyuh. Kadar kolesterol digunakan sesuai dengan kebutuhan fisiologisnya
