Judul: Kandungan Pati dan Kurkuminoid Simplisia Kunyit (Curcuma domestica Val.) sebagai Parameter Pemilihan Aksesi Terbaik
Abstrak: The quality of simplicia as medicine raw materials determined by percentage of certain metabolites components contained in the simplicia. The selection of turmeric best accession based on curcuminoids content as the main component and starch content as a matrix constituent. This research aimed to analyze adaptability of plants from its genetic effects of turmeric towards curcuminoids and starch content of turmeric simplicia from several accession to acquire best accession with high curcuminoids and low starch. The accession that were used such as BPTO, Ciemas, Nagrak, Ngawi, Wonogiri, and the last two from Balitro Bogor best varieties i.e. Turina-1 and Turina-2. Starch measurement used Luff-schoorl methods. Curcuminoids were measured using HPLC. Starch content of all sample is 2.361-3.421%. Turina-1 have lowest starch content is 2.361% and followed by accession of Ciemas is 2.565%. Curcuminoids contents of all sample is 4.776-5.793%. Accession of Ciemas have highest curcuminoids content 5.793%. Accecions from Ciemas selected for best accecions because it has high curcuminoids and low starch content.

Judul: Kandungan Kurkuminoid dan Daya Antioksidan Aksesi Temulawak (Curcuma xanthorrhiza Roxb.) asal Sukabumi
Abstrak: Curcuma xanthoriza Roxb. is one kind of curcums which useful as medicine plants. It containts curcuminoid which has antioxidant bioactivity. This study aimed to measure curcuminoids content and antioxidant bioactivity of Ciemas (Sukabumi) accessions compared with varieties of Kursina 3 from Bogor. HPLC method were used to determined curcuminoid content. The antioxidant bioactivity of both samples were evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical method. Percent yield ethanol 70 % extract of Curcuma xanthoriza Roxb. were 15.85 % (Kursina 3) and 19.94 % (accession). The curcuminoid content of Kursina 3 and acccession were 0.79 % and 0.99 %, respectively. The result of IC50 were 82.8 ppm (Kursina 3) and 47.97 ppm (accession) respectively. Based on the result of the study, Sukabumi promising lines curcuma has the potential to be further researched and developed as new varieties.

Abstrak: Remotely Operated Vehicle (ROV) is an underwater robotic vehicle that able to perform the underwater movement controlled from the surface via thetered cable and connected to the control system. The purpose of ROV is to observe and work underwater in accordance with the function of making of the robot itself. The ROV V. 2014 is improvement of the previous ROV developed by the Department of Marine Sciences and Technology, Bogor Agricultural University. The ROV V. 2014 has improved power supply system, thrust system, ballast system, and gripper systems. The making of a ROV is divide into four parts : design, programming, electronics, and mechanical/hardware. This new generation of underwater vehicle has dimensions of 65x35x40 cm, total weight ± 19kg, a system of ballasts with ballast tank 14.879 dm3 volume of space, a wide opening claw gripper with a maximum diameter of 8 cm, and 5 thrusters to move the robot horizontally and vertically, thetered cable of the 28 meter long to the surface and joystick to control the maneuver of the vehicle.
