Abstract

To achieve the real time data warehouse is strongly influenced by the process in the data warehouse known as Extract, Tranform, Loading (ETL). One way to optimize the ETL process is processing only data that undergoes changes on the On Line Transaction Processing (OLTP) system. This technique is known as Change Data Capture (CDC) which is designed to maximize the efficiency of the ETL process. In this research middleware was built as a place where the ETL process will be carried out, transaction data from the OLTP system will be captured and sent directly to the middleware for further processing. The method used to capture changes in OLTP systems is Change Data Capture (CDC) based on Event Driven Programming, where this technique relies on events that occur in OLTP in capturing data changes. Functional testing is done by making a simulation of the insert and update processes in test applications namely OLTP CRM system.The results of the research obtained are (1) Change Data Capture (CDC) based on Event Driven Programming can capture changes in data that occur in OLTP CRM database;(2) ETL process to load data from Normalized Data Store (NDS ) to data warehouse with Timestamp technique can load data that only undergoes changes that are processed to be loaded in Data Warehouse;(3) An increase in the amount of data that is processed has an effect on increasing processing time. Other factors that affect the value of process time are execution plan and cache memory

Abstract

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.

Abstract

Although many methods for optimizing DGplacement and its size in a network with the target of reducingsystem power losses and voltage profile have already beencommended, they still lack from several weaknesses. As a resultmuch can be done about to happen with new algorithms. Theproposed algorithms commonly have stressed their formulationson real power losses only and ignored the reactive power losses.Power systems reactive power injection plays an important rolein voltage stability control, thus the reactive power losses need tobe incorporated in optimizing DG allocation considering theirvoltage profile improvement. Whereas Particle SwarmOptimization (PSO) approach was proposed for finding theoptimal size of DG. This study work intended to apply both realand reactive power flow, power loss sensitivity factors and PSOmethod in finding the candidate buses for DG placement and itssize on Bali’s 150 kV transmission networks. The experimentalresults show that the proposed algorithm is indeed capable ofobtaining a good quality solution efficiently
