<![CDATA[Various types of daily necessities are available at all-round cooperatives. The Udayana University Karya Bina Sejahtera Civil Servants Cooperative. This cooperative is included as an all-round cooperative that sells various kinds of daily goods and transactions occur every day with considerable intensity. This causes the cooperative to be able to fulfill the demand for goods from the buyer and keep the items sold in good condition. So that in storing the stock of goods must be able to adjust so that the goods are not excessive in inventory or less in the inventory of goods to be sold. Seeing the problems described above, the author feels the need to build a system that can help the cooperative in determining the number of goods ordered. The recommendation system can be built with several methods. One method that can be used is to use the fuzzy logic method. Researchers want to do a study that aims to help in recommending ordering purchases of goods to be ordered based on the number of sales transactions of goods needed from existing data. To make a recommendation for the number of orders for goods, it will be calculated using the Tsukamoto Fuzzy Logic method which is considered suitable to assist in terms of recommending the number of goods purchase orders. With the calculation of this fuzzy logic, the cooperative will later be able to pay attention to the determination of the number of purchase orders for goods so as not to cause excess stock or stock shortages. The development of a system of recommendations for planning stock items can help the cooperative to provide a reference for the number of orders that must be ordered in order to reduce the occurrence of ordering errors as previously explained, such as excess stock or lack of stock]]>

<![CDATA[The design of balancing the load current on three-phase systems using a microcontroller ATMega 2560 is a tool that serves to reduce the power loss. Power loss due to the load current unbalance the current flows in the neutral phase on three-phase systems. Current flows in the neutral phase distribution transformer into a detriment to PT. PLN (Persero) for the power lost to the earth and can not be used by consumers. So that it will balanced the load current to reduce the value of neutral current. The tool is also equipped with a monitoring system that displays current magnitude of each phase including the neutral phase.The methods in making this tool is divided into two parts: first, the design of hardware consist of designing electronic components which are used by the current sensor circuits, relay, LCD (Liquid Crystal Display) etc. Second, the design of software is a tool listing program procedure including the monitoring program displays the current of each phase on LCD using the Arduino IDE. SCT013-030 current sensor used, the output of the current sensor is connected to the pin ADC (Analog to Digital Converter) microcontroller ATMega 2560. Then microcontroller process the data and generate a current value displayed on the LCD. The other result of processing current value is a command to enable or disable the relay that connects three-phase resource with single-phase loads.The result of the test design of balancing load current on three-phase system using a microcontroller ATMega 2560 succeed balancing the load current by moving the channel load of sequence number load the smallest connected to the phase with the current biggest load toward a phase that has a load current smallest when neutral current exceeds the limit is permitted. In this situation, the neutral current will not be possible be zero. In fact, the maximum current value for the neutral phase for PT. PLN (Persero) 50 amperes calibrated to 1 ampere and is used as a limit on this prototype. If the neutral current on LCD monitor exceeds 1 ampere, then there will be balancing of the load current. The current sensor measurement results are displayed on a monitoring approach measurement result using pliers ampere.]]>

<![CDATA[The quality of universities, especially study programs in Indonesia is measured based on accreditation conducted by BAN PT. According to BAN PT the quality is measured based on 7 main standards, one of them is Student and Graduate. One of the problems that still be the subject of discussion related to student failure is about the students who graduated not on time. Students graduating not on time are students who can not complete their studies in accordance with the provisions of time given. The existence of a graduate student is not timely of course cause problems and potentially drop out that affect the quality of education and accreditation. A system that predicts students' graduation is required by evaluating their learning outcomes. The timeliness of graduating students can be done with data mining techniques to find graduation patterns of students who have graduated which then used as a basis to predict students' graduation in the next year. This study showed that Naïve Bayes was able to classify the correct data testing on average by 86.16% and 13.84% error. In addition, other information obtained from the data testing used that the students who entered from the PMDK Pass graduated on time as much as 40%, other paths graduated on time by 26.7%, and pass filter exam on time 13.3%.]]>

<![CDATA[Evaluation Process performance do not match reality, and through a very complicated process. As the employees were assessed on one criterion alone but immediately get a promotion. Though these employees are not necessarily superior to the other criteria, the absence of standards or the weight of a definite value in determining the quality of its staff and the absence of a system that can provide an alternative solution to employee performance evaluation for a promotion. There needs to be a system that can facilitate the General Manager in taking decisions raise. If the decision-making process is aided by a computerized decision support system, is expected to subjectivity in decision making can be reduced and can be replaced with the implementation of all criteria for all employees, so expect employees with the ability (other considerations) the best are selected. By applying the concept of gamification is expected the decision support process becomes more attractive and employees become more motivated in their work.]]>

<![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).]]>
