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, Inhibisi a-Glukosidase dan Sitotoksisitas Ekstrak dari Beberapa Aksesi Kunyit (Curcuma domestica Val.)
Abstrak: Turmeric (Curcuma domestica Val.) is a medicinal plant family Zingiberaceae with curcuminoid content of the rhizome. This study aims to determine the content of curcuminoid, α-glucosidase inhibitory activity, and cytotoxicity test curcuminoids of turmeric extracts from several accessions. Curcuminoid content analysis was performed using HPLC. Inhibition of α- glucosidase performed in vitro with the substrate p-NPG. The cytotoxicity of curcuminoid extract of turmeric using BSLT method. The highest levels of curcuminoid owned by Ngawi, followed by Ciemas, Wonogiri, and Nagrak. Levels curcuminoids Ngawi of 24.50%. Turmeric extract the highest bioactivvity as α-glucosidase inhibitor activity is Nagrak accession with IC50 values of 207.093 μg/mL. Cytotoxycity test results showed that all samples have bioactivity and accession have the best LC50 value is Karanganyar at 19.090 μg/mL. Nagrak, Wonogiri, and Ngawi, has the potential to be developed into new varieties of turmeric with high bioactivity in inhibition α-glucosidase with IC50 moderate level.

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.
