Judul: Aktivitas Antioksidan Nanokurkuminoid Temulawak Lokal Ciemas Pada Tikus Sprague-Dawley Betina
Abstrak: Java turmeric (Curcuma xanthorrhiza) is a typical Indonesian plants that have antioxidant activity. Clinical testing showed that curcumin safe at high doses (12 g/day) but has low bioavailability. Delivery systems by making of solid lipid nanoparticles made to improve bioavailability of curcuminoids. This study aims to measure antioxidant activity of nanocurcuminoid coated solid lipid in female rat induced by CCl4. Analysis of antioxidant activity by measuring Malondialdehyde (MDA) levels and activity of superoxide dismutase (SOD), gluthatione peroxidase (GPX) and peroxidase (POX). Nanocurcuminoids size that obtained was 114.4±33.8 nm with polydispersity index 0.218 and adsorption efficiency 79%. The results showed that administration of nanokurkuminoid dose of 1500 mg/kg in female rats induced by CCl4 were able to reduce levels of MDA (4.34 nmol/mL) and increasing the activity of SOD (64.70 %), GPx (3208.02 mU/mL) and POX (3.13 mU/mL). These results indicate nanokurkuminoid have antioxidant activity.

Judul: Status Antioksidan Tikus Sprague-Dawley Betina dengan Pemberian Nanopartikel Kurkuminoid Temulawak Balittro
Abstrak: Curcuma (Curcuma xanthorrhiza) is an Indonesian herbs plant with antioxidant activity. This research aimed to measure the increasing of curcuminoids bioavaibility through the efectivity of nanoparticle curcuminoids as antioxidant for carbon tetrachloride (CCl4) induced rats. Nanoparticle curcuminoids was produced by homogenization-ultrasonication method showed results particle size of curcuminoids nanoparticle was 141.85±38.82 nm with polidispersity index was 0.233 and entrapment efficiency was 71%. During the treatment, rat’s body weight was increased. Clinical symptoms of rats (behavior and feces) was normal. Nanoparticle curcuminoids can decrease malondialdehide concentrations and increase peroxide, glutation peroxide, and superoxide dismutase activity.

Judul: 3D model reconstruction using aerial photo to measure object height
Abstrak: 3D reconstruction, especially for height extraction, using digital aerial photos taken from a non-metric camera and Unmanned Aerial Vehicle (UAV) is a challenging study. The purposes of the study are to determine the factors affect the accuracy of an object’s height reveal from a 3D model and establish procedures to deliver the optimal result. Two or more overlapping aerial photos can be constructed into the 3D model by applying the principles of collinearity and epipolar geometry using 3D reconstruction algorithm. Due to the instability of non-metric digital camera, the camera must be calibrated before 3D reconstruction is processed, in that way the quality of spatial extraction can be then measured. The study is conducted using 24 megapixels resolution Sony NEX7 digital camera and Hexacopter UAV. UAV was flown to a height of 50 m, 60 m and 70 m and placed at a certain position in order to get some height variations of camera. Camera Calibration Toolbox is utilized to calculate intrinsik parameters of the camera and a specific program is developed using MATLAB in order to build the 3D model and to obtain the object’s height. The result validation is done by comparing the height from 3D model with that one measured using Electronic Total Station. The accuracy of the object’s height up to 1 mm successfully achieved, with the largest height prediction error reaches 15.2 cm at 70 m flying height above ground level and average percentage error 4.07 for 20 objects.
