<![CDATA[Providing the right student scholarships will produce graduates who are permanent and reliable. Scholarships are usually given in the form of financial assistance, both education money and even pocket money (living expenses). This research classifies the accuracy of awarding student scholarships, where in the research conducted the number of scholarship recipients was not on target, resulting in the scholarship recipients not being serious about attending lectures and even dropping out of studies. The research method, namely the survey research method, is a research method that is carried out using surveys or data collection through research respondents. The algorithm used in analyzing the data is the KNN algorithm. The purpose of this study was to apply data mining using the KNN algorithm to find out the classification results of the accuracy of awarding student scholarships. The results of this study make a classification of scholarships, namely 19 students are eligible to receive scholarships and 49 students are not eligible to receive scholarships.]]>

<![CDATA[PT INALUM Power Plant is a company that operates a hydropower plant consisting of the Siguragura (SGP) and Tangga (TNP) power stations. So that requires it to continue to optimize its maintenance policy. Even though maintenance activities have been carried out, the frequency of damage to each unit still occurs frequently. As a result, the unit trips (experiencing termination), namely forced outage, which affects the amount of downtime. To overcome this problem, in this study the method used to determine the performance of the power plant is the Generating Availability Data System (GADS), then to determine the reliability and rate of failure using an exponential distribution. Meanwhile, to repair damage to turbines & generators using FMEA analysis. MTR bushings were repaired routinely for 51.306 hours (±2 days) or 102.612 hours (±4 days). 46% and in the Ladder Hydroelectric Power Plant it occurred in the T/Ge3 unit of 2.80%. The appropriate evaluation action is to carry out maintenance with the type of periodic maintenance and preventive maintenance. Particularly T/Ge1 PLTA Siguragura on the air cooler & metal cooling tube component and T/Ge3 PLTA Tangga on the MTR Bushing component. The right maintenance strategy to minimize forced outage is to review planned maintenance on the air cooler & metal cooling tube for routine flushing for 35,287 hours (±1 day) or 70,574 hours (±3 days).]]>

<![CDATA[The toddler period is a golden period that must be put to good use by parents. The golden period is a determinant for the growth and development of children. Malnutrition in children can lead to various diseases that can hinder the growth and development of children. Posyandu Desa Tanjung Garbus Kampung is an integrated service center that provides public health services. Lack of knowledge and experience of Posyandu health workers in Tanjung Garbus Village Village is one of the problems in diagnosing malnutrition in toddlers because it is only based on the toddler's weight and height. The dempster shafer method is a method in expert systems that applies a mathematical theory for proof based on a function of belief and reasonable reasoning (belief function and reasonable thinking), which is used to combine separate pieces of information (evidence) to calculate the likelihood of an event. With this system, it is expected to be able to diagnose malnutrition in toddlers quickly and efficiently.]]>

<![CDATA[The development of information systems and technology including expert systems that use facts, techniques and knowledge and reasoning in solving problems. The expert system that is currently developing is a system that adopts the knowledge of an expert in a particular field. In everyday life, we often encounter problems faced by humans, including disease problems in the human body, so we need to consult an expert in the health sector to solve these problems. However, sometimes patients with disease cannot consult an expert due to the large number of patients as well as time and cost issues. In light of these existing problems, it is necessary to develop a system that can help these patients, namely by developing an Expert System model for diagnosing Polycystic Ovary Syndrome (PCOS) using the Naïve Bayes method. The Naïve Bayes method will assist in diagnosing the disease.]]>

<![CDATA[Analysis using a fuzzy approach is a solution to the problem of differences in the units of variables to be calculated correlation patterns. Almost all conventional analysis is approached with fuzzy methods. This results in calculations that are closer to the field situation. The Sugeno method is one of several methods in fuzzy analysis used in this study. Satisfaction is a situation where consumers are positive about a service or producer (service/product provider), in economics to find out this, several studies have been conducted. However, in the study, calculations were carried out using a firm set (crisp). While in this study, calculations were carried out using the Sugeno method. The results obtained in this study are the calculation of student satisfaction levels using the Sugeno method consists of several stages, namely: 1. Formation of fuzzy sets of product quality variables, 2. Formation of fuzzy rules that may occur where there are 42 rules, 3. Defuzzification (affirmation) using the weighted average calculation method which produces a defuzzification value of 67.47. Furthermore, research can be developed again using other parameters in determining the level of student loyalty until college graduation.]]>
