Efisiensi Pemakaian Daya Listrik Menggunakan Kapasitor Bank

Pada umumnya beban pada jaringan listrik adalah beban induktif seperti motor listrik, heater,neon ( yang menggunakan trafo ), lampu mercury dan lain-lain, jadi beban listrik kebanyakan adalahbeban induktif yang membutuhkan daya reaktif. Jika beban rekatif ini dipikul oleh pembangkit tenagalistrik, maka arus yang mengalir dijaringan juga semakin besar yang berakibat factor dayanyamenurun dan jatuh tegangan pada ujung saluran ( ke konsumen ) meningkat.Salah satu langkah efesiensi penggunaan energi listrik di konsumen adalah dengan memasangperalatan penghemat energi listrik ( energy server ) yang digunakan baik disektor industri, bisnis /komersial maupun rumah tangga. Peralatan penghemat energy listrik tersebut adalah kapasitor bankyang berguna untuk menginjeksi daya reaktif pada titik-titik dimana terjadi tegangan jatuh, sehinggadiperoleh profil tegangan yang baik dan rugi daya yang lebih kecil.Kapasitor bank dapat memperbaiki power factor( Cos phi ) untuk meningkatkan kwalitas dayasekaligus meningkatkan effesiensi pemakaian peralatan listrik konsumen dan akhirnya effesiensienergi listrik yang disediakan oleh penyedia tenaga listrik

The Mediation Effect of Trusting Beliefs on the Relationship Between Expectation-Confirmation and Satisfaction with the Usage of Online Product Recommendation

Online Product Recommendations (OPRs) are increasingly available to onlinecustomers as a value-added self-service in evaluating and choosing a product.Research has highlighted several advantages that customers can gain from usingOPRs. However, the realization of these advantages depends on whether and towhat extent customers embrace and fully utilise them. The relatively low OPR USAgerate indicates that customers have not yet developed trust in OPRs’ performance.Past studies also have established that satisfaction is a valid measure of systemperformance and a consistent significant determinant of users’ continuous systemusage. Therefore, this study aimed to examine the mediation effect of trustingbeliefs on the relationship between expectation-confirmation and satisfaction. Theproposed research model is tested using data collected via an online survey from626 existing users of OPRs. The empirical results revealed that social-psychologicalbeliefs (perceived confirmation and trust) are significant contributors to customersatisfaction with OPRs. Additionally, trusting beliefs partially mediate the impactof perceived confirmation on customer satisfaction. Moreover, this study validatesthe extensions of the interpersonal trust construct to trust in OPRs and examinesthe nomological validity of trust in terms of competence, benevolence, andintegrity. The findings provide a number of theoretical and practical implications.&nbsp

The Significance of Introducing Culture in EFL Instruction

EFL students many times made mistakes in using the English expressions and led to misinterpretations or even acceptable message of their utterances. This is due to their lack of cultural awareness or their understanding towards L2 culture. Therefore, EFL teachers should think of how to give position to the L1 and L2 culture in their teaching and learning process of EFL instructions.To solve the problems, there are some approaches used to introduce the target language culture, by knowing the obstacles that the learners frequently made

Transformational Linguistics and the Implication Towards Second Language Learning

The essence of Chomsky's approach to language is the claim that there are linguistic universals in domain of syntax. He felt confident to show that syntax can be defined for any given language. For Chomsky, the nature of such mental representations is largely innate, so if a grammatical theory has explanatory adequacy it must be able to explain the various grammatical nuances of the languages of the world as relatively minor variations in the universal pattern of human language. In teaching English as L2, therefore knowing syntax and grammar of the language is important. Transformational Generative Grammar gives adequate elaboration in understanding them. Thus, the learners are expected to be able to avoid such ambiguity in interpreting the deep structure of a sentence since ambiguity will lead other people as the listeners or hearers of the speakers to misinterpret either consciously or unconsciously
