Judul: Aplikasi Building Information Modeling (BIM) Menggunakan Software Tekla Structures 17 Pada Konstruksi Gedung Kuliah Tiga Lantai Fahutan IPB, Bogor
Abstrak: Building Information Modeling is the process of managing building data during the construction cycle. In this research Building Information Modeling (BIM) by using Tekla Structures software version 17 was applied on a three floors building of Fahutan IPB. This software has many good advantages in order to be considered as the best one solution in solving civil engineering problems. This research objective was to apply one BIM software to model the three floors building of Fahutan IPB in 3D and 4D, and to present the integrated information aspects of that building by using Tekla Structures software. In modeling the building, it required the as built drawing and schedule which was obtained from the Directorate of Facilities and Property of IPB. The building modeling process in this study was first started by drawing the structure such as foundations, columns, beams, slabs, reinforcement and followed by the implementation of schedule for each job structure. The result was four dimensions (4D) modeling that was poured in 3D modeling with contained scheduling features in one file of Tekla Structures. This research produced information that represented in Tekla Structures software such as building dimensions, volume of material, and output of project implementation schedule.

Judul: Penerapan Building Information Modeling (BIM) pada Pembangunan Struktur Gedung Perpustakaan IPB menggunakan Software Tekla Structures 17
Abstrak: Building Information Modeling (BIM) is an approach to building design, construction, and management. Tekla software is a new revolution in the field of engineering structures has several advantages over other application program that allows to create and manage data accurately and in detail, and can create 3D models of structures and materials without forgetting the complex structure. This study was intended to conduct IPB’s library building modeling with BIM software (Tekla Structures 17) in 3D and 4D and to explore the advantages of BIM that easier the coordination, speed the information, and save the cost. The research method involves the preparation stage, secondary data collection, and modeling using Tekla Structures 17. In the modeling stage, the first thing to do was to create a grid, and continued with the structure of the building foundations, pile caps, beams, slabs, and columns from floor to roof. In modeling with Tekla software, dimensions and type of materials used can be selected directly on each piece. Tekla software has tools that can simplify the design up to the time of implementation, including Orginizer Model and Task manager. With BIM, all building information was presented into one file so that it can save time and costs. BIM 4D modeling is very good if applied on existing development in Indonesia.

Judul: Proses peroksidasi lipid kelinci yang hiperlipidemia pada pemberian senyawa penurun kolesterol
Abstrak: Radikal bebas banyak mendapat perhatian akhir-akhir ini karena dianggap memiliki peran yang cukup signifikan dalam terjadinya berbagai penyakit degeneratif. Hiperlipidemia adalah salah satu faktor resiko aterosklerosis yang mengarah pada penyakit degeneratif tersebut. Penelitian ini bertujuan mengukur konsentrasi lipid peroksida pada darah kelinci yang hiperlipidemia dan pengaruh senyawa penurun kolesterol terhadap konsentrasi lipid peroksidanya. Sebanyak 20 ekor kelinci jantan galur New Zealand white dibagi menjadi empat kelompok percobaan, yaitu kelompok normal yang hanya diberi pakan standar, hiperlipidemia yang diberi pakan aterogenik (kolesterol 0.5% dan minyak kelapa 5%), lovastatin yang diberi campuran pakan aterogenik dan lovastatin (57 mg/hari), dan ekstrak yang diberi campuran pakan aterogenik dan ekstrak ramuan daun jati belanda. Analisis lipid peroksida darah menggunakan metode tiobarbiturat (Yagi 1994) yang mengukur senyawa malonaldialdehida (MDA) menggunakan spektrofotometer pada λ = 532 nm. Hasil percobaan menunjukkan pemberian pakan aterogenik pada kelinci menyebabkan peningkatan konsentrasi MDA, yang berarti meningkatnya proses peroksidasi lipid dalam tubuh. Kelompok hiperlipidemia mengalami peningkatan konsentrasi lípid peroksida darah sebesar 163.76% bila dibandingkan kelompok normal (1.30 ± 0.38 nmol/ml). Lovastatin dan ekstrak ramuan daun jati belanda dapat berperan sebagai antioksidan dengan cara menurunkan konsentrasi lipid peroksida darah sebesar 46.92% dan 53.03% berturut-turut pada minggu ke-8 perlakuan dibandingkan kelompok hiperlipidemia.
