<![CDATA[Natural dyes are economically and environmentally superior to ruthenium-based dyes because they are cheap and non-toxic. In this study, natural dyes were extracted from mangosteen peel waste. Color extraction was carried out with three types of solvents (distilled water, methanol and ethanol) which had been acidified with 10% citric acid and with a ratio of material: solvent (1: 4, 1: 6, 1: 8 w / v). The photochemical properties are studied by UV-Vis spectrophotometer and FTIR spectroscopy. The absorption peak of the three types of solvent occurs at different wavelengths. The presence of carbonyl (C = O) and hydroxyl (OH) groups contained in anthocyanins can attach coloring to the surface of TiO2. Ethanol solvents with a ratio of 1: 8 produce the lowest photon energy at wavelength and absorption coefficient of 539.00 nm and 2,008 km-1 respectively. The lowest band gap of the dye helps electrons move rapidly from the valence band to the conduction band and only requires less energy for electron recombination which will increase the performance of the DSSC.]]>

<![CDATA[Efficient and effective IT resource management is needed to create solutions and minimize the risk of implementing Information Technology (IT) in organizations. The COBIT 5 framework helps in the information technology audit process because it covers all elements of the information technology used. Training Institute X is an institution to obtain certification from Tourism courses/training. Currently Training Institute X is developing information technology utilization in improving the quality of business processes in IT systems according to the vision, mission and purposes of the Training Institute X set. The need for an audit is because in its implementation there is still the use of information technology that has not been properly managed and alignment in the information technology process and business processes that have not yet been evaluated. In this paper the method to be used is COBIT 5 by using 3 domains that have been mapped according to the company's objectives, namely EDM, DSS and APO. Capability level measurement results in each domain of IT governance audit use COBIT 5 on the EDM and APO domains on level 2 (Managed process) and DSS on level 1 (Performed process).]]>
