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.

Judul: Analisis Kombinasi Pondasi Konstruksi Sarang Laba- Laba dengan Bored Pile untuk Mereduksi Settlement pada Gedung XYZ.
Abstrak: Pondasi terbagi dua jenis yaitu pondasi dalam dan dangkal. Pemilihan jenis pondasi bergantung pada beban yang harus didukung, kondisi tanah dan biaya pembuatan pondasi yang dibandingkan terhadap biaya struktur atasnya. Penelitian ini bertujuan mengetahui besar kemampuan kombinasi pondasi konstruksi sarang laba-laba (KSLL) dengan bored pile untuk mendukung beban dan mengetahui besar penurunan yang terjadi apabila mengkombinasikan pondasi KSLL dengan bored pile. Pemodelan gedung dan analisis pembebanan menggunakan software ETABS 9.7.0. Kemampuan kombinasi KSLL dengan bored pile dalam mendukung beban sebesar 5.57 ton/m2. Penurunan seketika yang terjadi sebesar 1.28 cm dan penurunan konsolidasi yang terjadi 10.4 cm, dengan demikian total penurunan yang terjadi sebesar 11.68 cm dan total biaya yang dikeluarkan sebesar Rp.2,449,920,286.00. Reduksi penurunan yang terjadi sebesar 48.42 cm setelah dilakukan kombinasi pondasi KSLL dengan bored pile.

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
