Technological developments can help human in their work. National Standardization Agency of Indonesia often gives awards for each employee based on the achievements of an employee. With the award given, it is expected that employees will motivated to provide the best work results for the company. The current rating system for National Standardization Agency of Indonesia employees is still by distributing questionnaires, then the results of the questionnaire are recapitulated and ranked based on the highest score to the lowest value. The assessment process currently take a long time so the information obtained is not fast. With the existing problems, we need a system that can help the company in determining the best employees with predetermined criteria. Based on the problems that occur, it need decision support system that can help the company to choose the best employee. The method used in decision making is Simple Additive Weighting (SAW). Decision making with Simple Additive Weighting method is used for decision making using the weighted addition method. Calculations in employee evaluations are carried out directly by superiors with prescribed considerations. The system developed can determine the employees who have the best performance, and helpful for decision maker to make final decision.

The culinary business is now increasingly developing and competition is increasing, so it requires a strategy to market the products to be sold. In the business sector, the results of the implementation of FP-Growth algorithm data mining can help business people find opportunities from consumption trends so that culinary business people can find out what types of products currently have the highest rating in the community so that managers can provide menu recommendations so they can increase sales turnover. The data required is a certain period of transaction data which is analyzed to produce product recommendations by the association rules. The design of this application uses HTML as the base system used in making websites, PHP as a means to develop websites, and SQL as a medium for data storage and processing. The testing process begins with the login process, then determines the support and confidence parameters, and determines the transaction time period. From the conclusion, managers can determine marketing strategies by increasing the stock of raw materials in beverage products that have the highest itemset value. Then the product with the lowest itemset value can provide promos or discounts on the purchase of goods to attract consumer buying interest.

Equitable development is always encouraged by both the central and regional governments. However, in practice it is not easy and goes through a fairly long process. Likewise, the efforts of the government, especially the province of Lampung, are trying to carry out development through equal distribution of electrical energy to areas where the National Cross Border Center (PLBN) is located, such as Mesuji Regency, although it is still unstable and uneven throughout the village. The condition of the lack of electricity supply causes blackouts to occur frequently and in a relatively long period of time. This greatly affects community activities and is no exception in terms of education or at school, especially in the use of technology-based learning media and school administrative matters, such as filling out report cards and so on. Nowadays, filling out report cards must be done through technology-based applications that require electronic equipment such as laptops to use them. The design of the School Solar Panel System (SSPS) is intended in an effort to increase the availability of electricity in supporting teacher professionalism in carrying out learning activities. So that with the design of the School Solar Panel System which will be implemented later, the electricity supply remains available even though there is a power outage.

Short-circuit often occur in electricity sub-station SP-2 Tanah Miring, Merauke -Papua which caused by malfuction of Over Current Relay (OCR) and Ground Fault Relay (GFR). In enhancing the performance, it takes analysis of relay coordination using ETAP. At maximum load of feeder SP-9 (917 A) an OCR setting is 4.5 A with TMS 0.46 seconds, GFR setting is 4.58 A with TMS 0.17 seconds. At minimum load (324 A) OCR setting is 1.62 A with TMS 0.29 seconds as for the GFR setting is 1.62 A with TMS 0.22 seconds. At the maximum load of feeder Kebun Cokelat (995 A) an OCR setting is 4.97 A with TMS 0.46 seconds as for GFR set is 4.97 A with TMS 0.17 seconds. At minimum load 100 A, OCR setting is 0.5 A with TMS 0.43 seconds while GFR setting is 0.5 A with TMS 0.35 seconds. Furthermore, if the minimum load reach 98 A then the coordination time of GFR and OCR is 0,5 seconds. This analysis found that relay prohibited to operate above 1100 A (maximum) and below 98 (minimum) due to if it working out of the load range then the coordination time would not meet the manual standard.

Drug abuse has become so paramount among members of society. Although, the initial decision to take drugs is typically voluntary among victims. As drugs are constantly been used, the ability to exert self-control on them is relatively impaired. Thus, abuse is witnessed in different age groups, gender, and celebrities from all walks of life. While addicts become such owing to several factors of curiosity and peer pressure, recreational purpose, source of inspiration, and more, the effect of these drugs can lead to depression, brain stimulation, and hallucination. Managing drug abuse through behavioral or pharmacological means is intended to help addicts stop habitual drug use. Oftentimes, rehab is not effective because the desired change is absent while a proper technological-driven approach to track sobriety and relapse in compulsive drug seeking and usage is also missing. Consequently, in this research, user-friendly and interactive sobriety and relapse predictive management application is developed. Here, addicts' behavioral and demographics with major relapse monitoring factors were clustered to predict the likelihood of relapse. The relapse predictive system using cognitive behavioral patterns, adopts the logistic regression algorithm of the Bayesian network for both training and testing. The essence is to ascertain users’ addiction level, analyze and track sobriety and relapse in order to uncover drug addiction patterns, discover the probability of relapse occurrence towards recommending sustainable rehabilitation decision support
