Judul: Analisis Daya Dukung dan Pemodelan Struktur Pondasi Bored Pile Bangunan Penghubung antar Gedung RSBA Jakarta Timur.
Abstrak: Modeling of a building can be shows by two dimension (2D), three dimension (3D), and four dimension (4D). Modeling proceses when planning or post construction purposed to get more detail information about the structures. Bored pile are used to support and transmitted the upper load to underlying a stronger soil layer. The structures must be design by safety factor that determined so that the structures are safe to cover the overload possibility. The study aims to analyze and modeling the bored pile foundation of connecting building. The methods are data collection, modeling, analysis upper and down structures, and showing the result. Software Tekla Structures and SAP2000 are merged to modeling and analysis. The study started at February to June 2015 in Jakarta and IPB Campus. Foundation, column, beam, slab and reinforced will modeling by Tekla Structures 17. Result of analysis shows that foundation calculated base on SPT data. Meanwhile, value of safety factor K4a and K4b columns are higher than SF standard (2,5). Settlement of group foundation is 11,97 mm, and still below of permitted settlement 80 mm.

Abstrak: Analysis and structure evaluation is necessary in order to achieve a better result, because a successful construction depends on good planning and execution at site will take the rest. Calculation must refer to prevailed regulation. This script is going to evaluate and analyse Agrotropica library of Bogor Agricultural University. The library has been built precisely next to LSI. The building which was designed by PT Fajar Adhi Karya has four main floor, basement and lift machine room control. The method of this research was data collection through As Built Drawing, building modelling using SAP 2000 version 14, define frame section of structure, define and assign load case to it’s model, design the reinforcement of concrete from SAP 2000 version 14’s output such as internal force and compare the result of measurement to existing condition. This research refer to SNI 03 2847 2002 which contained concrete reinforcement design regulation. Structure evaluation input data must have according to As Built Drawing such as dimension, reinforcement type, material type, in order to get effective amount of reinforcement. Stress reinforcement on beam calculation has the biggest differences getting to 166%, and shear reinforcement smallest space 89 mm that hard to execute at the site. Column stress reinforcement evaluation has to be checked towards X and Y direction, all of column in this building was safe except K4 column type toward y direction and according to calculation that ultimate shear force didn’t exceeded nominal shear force, in other word all of column shear reinforcement type in this building is safe. Slab reinforcement design has been planned by moment coefficient method with two direction. It can be seen that N, O, P slab type has larger space than calculation, it need maximum space 120 mm on x direction and 130 mm on y direction but it has been set by M8 – 150 wiremesh which mean 150 mm x direction and 150 mm y direction at site. Pilecaps calculation result shows that it’s need shear reinforcement because ultimate shear force has exceeded nominal shear force. Amount of Stress reinforcement on P4, P8, P9 pilecaps type at site less than calculation because ultimate moment was too big. There are some differencess between calculation and existing condition that may caused by input load data to its modeling and regulation which used by designer.

Judul: Characteristic of chili drying (Capsicum annum L.) as a natural dyeing cosmetic
Abstrak: Chilli (Capsicum sp.) contains carotenoids, which are a group of natural pigments consist of red, orange or yellow color. Carotenoids can be dissolved in lipid so that they can be applied to oil-based cosmetic ingredients. Therefore, chilli is potential to be developed as cosmetic colorants. However, pungency of red chili needs to be removed because it is irritating and it provides stinging sensation to skin. Red chilli was investigated as a potent material for a cosmetic colourant in this research because it has a nice uniform red color and has a pungency level less than cayenne pepper. The purpose of this research was to investigate the influence of blanching on drying characteristics of red chilli using a tray dryer, determine the proper time of chili blanching in sodium bisulfite solution, examine color changes stability of red chili powder as a cosmetic dye, and analyze the effect of oleoresin extraction on color and pungency level of red chili powder. The results showed that blanching could affect the drying characteristics. Blanching the chilli for 9 minutes prior drying could speed up the drying rate of chilli and thus the drying time, therefore, the chilli achieved the desired moisture content fast. Sodium bisulfite solution of 0.2%, used as the blanching media, could maintain the color well. However, longer time of blanching might cause several pigments soluble in the blanching media. Blanching the chilli for 9 minutes was able to maintain red color after the stability tested and after extraction of oleoresin. Therefore, blanching red chilli in a solution of 0.2% sodium bisulfite for 9 minutes prior drying is concluded as the best treatment to retain the color of red chilli powder
