Abstract

The imbalance between the nutritional intake of pregnant women to meet the needs and energy expenditure must always be monitored, because the imbalance itself can result in Chronic Energy Deficiency both in mother and fetus in the womb. Therefore it needs an appropriate food composition to meet the nutrients and energy for pregnant women, so it can help them to determine their own food. The problem of food composition for pregnant women can be solved by hybrid genetic algorithm and Simulated Annealing. The purpose of combining this method is to produce a better solution than using a genetic algorithm alone. This problem solving process have used crossover method is one-cut point, mutation using reciprocal exchange method, selection using elitsm, and Simulated Annealing. Based on the results of the test of the parameters used in the optimization system of food composition that using genetic algorithm hybrid and Simulated Annealing, was obtained the best parameter values ​​are: population number = 2900, Cr = 0.4, Mr = 0.6, T0 = 1, alpha = 0.7 and the number of generations = 220. So the results of the system is in the form of food composition recommendation using hybrid genetic algorithm and Simulated Annealing that can meet the tolerance limit set by the nutritionists at ± 10%.

Abstract

Coal is a fossil fuel that is often used by industrial companies as a source of energy and power as a raw material for steelmaking. Coal is obtained by industrial companies through a sale and purchase transactions conducted with coal mining companies. Price is a major factor in the transaction process, because industrial companies need to design an expenditure budget every month before making a transaction. Budget design is done to maximize the company's money to meet all the needs of the company. Therefore, the prediction of coal price will be very beneficial for industrial companies that will buy coal products to know the estimated price in the future. The method used to make the prediction process is the method of Extreme Learning Machine (ELM). ELM has the advantage of fast computing time and small error rate, so ELM does not require a long time in the learning process. Based on the result of research, the best Means Absolute Percentage Error (MAPE) score is 3,926804% for training process and 7,360343% for testing process.

But, in its implementation is still not optimal and there are constraints on the delivery and support of IT services such as the lack of references and of procedures in several processes that causes the process is not running optimally, the existing human resources are still inadequate in terms of skills and numbers. Diskominfo Tulungagung has never evaluated IT governance before. Therefore, an evaluation of information technology governance is needed using the COBIT 4.1 platform of Deliver and Support (DS) domains. The purpose of this study is to obtain the maturity level that obtained from the results of questionnaires and interviews with correspondents based on RACI Chart. The gap value is calculated between the current maturity level and what is expected by diskominfo. Based on previous calculations, recommendations is produced. From the results of the maturity level calculation, the average result of the DS domain is 1.50 and the gap value is 1.00 until 3.00. To achieve the expected maturity level, researchers provide recommendations in the form of suggestions that are doing good planning, formally documenting and making a Standard Operating Procedure (SOP) document for each DS domain process. These are recommendations are expected to be implemented by field of E-Government Organization to achieve goals in better management of IT services.
