One of the negative impacts of ICT is the stress caused by the inability to adapt to the technological environment, where the behavior can affect the mental and behavior that impact on user satisfaction and decreased performance. Technostress can generally be defined as the mental stress that employees experience because of the use of Information and Communications Technologies in the workplace. Factors of age and gender in previous studies revealed that old age tends to avoid technostress, and the male gender have high technostress level because they always want to find new things and try a new technology. Previous studies that have not yet seen the effect of differences age perceptions between cognitive age (young spirits) and chronological age (actual age) to technostress into a separate research that will be conducted by researchers. The results of this study prove empirically that the more a person has a cognitive age (young spirited) can reduce the influence of people experiencing technostress. Technostress was also proven to affect satisfaction, performance. The main factors trigger technostress from the results of this research is techno overload, techno uncertainty and techno insecurity. The results of research implications also show that technostress has a relationship to the user's intention to continue the use of technology.","PeriodicalId":165045,"journal":{"name":"2017 3rd International Conference on Science in Information Technology (ICSITech)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131590189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to proper grinding process, water temperature settings also become an important part. Grinding and brewing process must be done in a short time so that the taste of the coffee bean is not lost and the quality is maintained. A control system based on PID (Proportional Integral Derivative) is used to maintain proper water temperature. The components used is LM35 temperature sensor, Solenoid Valve, AC dimmer, and DC Motor that is connected to a Nuvoton NUC140 module that serves as the main controller of the system. Temperature control is done by adjusting the voltage of the AC dimmer circuit to heat the element with the PWM changes removed from the microcontroller. The PID parameter is determined using the Ziegler-Nichols method. The test results with Kp = 13, Ki = 116, and Kd = 29 systems have a response with a constant time of 613 seconds and the air temperature can be stable at 90 ° C with a steady state error of 1.1%. Overall, the system can process 8 grams of coffee beans for 5 minutes started from grinding the coffee beans to brewing.","PeriodicalId":165045,"journal":{"name":"2017 3rd International Conference on Science in Information Technology (ICSITech)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129981791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The increasing number of participation and the need of immediate response encourage the use of text mining to classify the complaints and proposals automatically. A classification model was built using Support Vector Machine (SVM) algorithm. This study was the first part of research on community complaint and proposals before text clustering and visualization. The result of model development for classifying documents showed that classification model with stemming and synonym recognition was the most accurate among others with 91.37% accuracy rate. Adding the number of training data would improve the accuracy. Based on classification result, the problem of flood and transportation became the most reported problems during January and February 2016.

In those communication processes, there are knowledge transfer or exchange processes that must be covered and managed to accomplish the goal of e-government application. Furthermore, knowledge, rapidly evolving, is increasingly recognized as a powerful strategic resource for efficiency by all types of organizations and institutions either public or private. As the proposed solution, those processes can be covered by Knowledge Management (KM) approach. This paper aims to deliver insight into key drivers, benefits, challenges, KM system types and critical success factors for KM implementation in e-government. A total of fourteen research papers have been reviewed by using systematic literature review method named Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA).

This limitation usually occurs in the form of actuator input saturation as the constraints of the system. To handle this input constraint, Model Predictive Control (MPC) is used as one of the popular advanced control technique in an industrial process to control a system. MPC contains quadratic objective function having constraints on the variables which must be resolved at each sampling time to produce an optimal control input to the system. This process of optimizing a certain quadratic function is called Quadratic Programming (QP). The computation of QP is usually slow and makes MPC takes a longer time to produce an optimal control input compare to other control technique especially in the online computation for real time embedded application. This problem can cause undesired result when used to control fast dynamic system such as BLDC motors. To overcome this problem, an iterative algorithm of Algorithm-3 is used as a fast QP computation solver. In this paper, MPC will be implemented to control the speed of BLDC motor using Arduino Mega 2560. Before implementation, system modeling, controller designing, and simulation are done using MATLAB. For the sake of comparison, the performance of MPC using Algorithm-3 will be compared with classic control techniques such as PID. From the results, it can be observed that MPC gives better performance than PID and it is shown that MPC capable to handle input saturation of the system better than PID.","PeriodicalId":165045,"journal":{"name":"2017 3rd International Conference on Science in Information Technology (ICSITech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129745006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
