The application of information systems with various types of convenience offered can reflect the quality of service of an organization, the quality of service can be said to be very good if the service meets the needs and expectations of users. This kind of evaluation can be done by applying a tested model but problems arise when latent variables in the method used are not fully able to identify factors that influence user satisfaction. From the results of research using the end user satisfaction model, the R-Square value is 0.653, which means that 65.3% of user satisfaction can be found through latent variables found in the EUCS model while the remaining 34.7% can be explained through external variables. This study aims to analyze external factors outside the EUCS model, one of which is by using the information system quality variables contained in the Delone and Mclane information system success model. The way to do this is to add an external variable to the EUCS model and then analyze the outer model and analyze the structural model using the structural equation model. The results showed that the independent system quality variable has a t-statistic value of 3.445 or greater than t-table 1.96 which means that the external latent variables of the Delone and Mclean model can be used to explain the satisfaction factors (from the external variable side) of the user information system on the EUCS model.
Pengembangan konsep kendaraan Low-Cost Green Car (LCGC) dan zero emission menjadi fokus penelitian pada beberapa negara. Hal ini dilatarbelakangi cadangan bahan bakar minyak yang terus menurun dan bahaya pencemaran lingkungan. Motor listrik merupakan satu – satunya penggerak utama yang dapat diaplikasikan pada mobil listrik yang mengusung kedua konsep tersebut. Pada generasi awal pengembangan mobil listrik, motor DC menjadi solusi yang paling sesuai dikarenakan kemudahan pengoperasiannya dan pengaturan kecepatannya. Setelah teknologi kontrol vektor untuk motor induksi ditemukan dan dikembangkan, motor induksi mulai dipakai oleh beberapa pabrikan mobil listrik. Pada kontrol vektor, fluks dan torsi pada motor induksi dapat dikendalikan secara terpisah sehingga pengaturan motor induksi menyerupai motor DC. PMSM merupakan satu – satunya jenis motor listrik yang mampu menyamai motor induksi sebagai penggerak mobil listrik. Namun, PMSM memiliki kekurangan yang sangat vital yaitu mudah mengalami kerusakan magnetisasi akibat panas atau reaksi armature, sehingga diperlukan penelitian lebih lanjut untuk mengaplikasikan PMSM pada mobi listrik. Motor listrik jenis SRM banyak digunakan pada mobil hybrid yang memadukan penggunaan mesin berbahan bakar minyak dengan motor listrik. SRM memiliki banyak kekurangan apabila diaplikasikan pada mobil listrik berskala kecil namun sangat sesuai untuk diaplikasikan pada mobil listrik berskala besar seperti bis.
Gardenia Plants is a similar plant to jasmine flowers with another name of gardenia jasminoides which means flowers and similar to jasmine flowers that have a very fragrant distinctive aroma. This research is aimed 1) to find out whether processed of leaves kacapiring can be used as the main ingredient of jelly making, 2) to tell the extent of the favorite and the quality of jelly, leaves kacapiring in terms of color, aroma, texture, and think, 3) for the jelly leaves kacapiring with jelly leaves cincau. This type of research used is experimental research, organoleptic test, and the comparison. The data collected from the organoleptic test to be analyzed statistically descriptive using the program of SPSS 20, 0 for Windows. The leaves of kacapiring can be processed into jelly, but not with the quality of the jelly, 2) based on the results of the hedonik, an average 3,55 of the panelists said like in terms of color, aroma, texture, and taste, 3) based on the results of the quality of hedonik get results in terms of color an average of jelly kacapiring 4, 48, very green, the smell of 3,96 a little smell, texture, stood a little chewy, and the jelly kacapiring 3,96 is bitter, 4) based on the results, the authors concluded that the cincau jelly leaves has better quality than kacapiring jelly leaves
The wind can be used as a power generator. Because of Indonesia have a huge potential of wind power made wind power generators to be one the best solution to overcome of limited energy problems. The quality of electrical power is an issue that they encountered in wind power generators. The problem can be the deviation of voltage, current and frequency can lead to failure or incorrect operation on energy consumer appliances. One of important element in the power generation system is a generator. In this research, conducted simulating and analysis the result of the controlled wind turbine induction generator. Control carried out using PI control (Proportional Integral). Optimal values obtained at kp = 10 and ki = 30 at a wind speed of 12 m / s with a settling time of 3 seconds. Keywords : proportional, integral, induction generator, wind turbine AbstrakAngin dapat dimanfaatkan sebagai salah satu sumber pembangkit tenaga listrik. Mengingat Indonesia merupakan negara yang sangat besar memiliki potensi tenaga angin menjadikan pembangkit listrik tenaga angin menjadi salah satu solusi yang tepat dalam mengatasi masalah keterbatasan energi. Kualitas daya listrik merupakan masalah yang ditemui dalam pembangkit listrik tenaga angin.Masalah tersebut dapat berupa penyimpangan tegangan, arus maupun frekuensi yang dapat menyebabkan kegagalan ataupun kesalahan operasi pada peralatan-peralatan konsumen energi listrik.Salah satu elemen yang penting dalam sistem pembangkitan listrik yaitu generator. Dalam penelitian ini dilakukan simulasi dan analisa hasil pengendalian wind turbine induction generator. Pengendalian dilakukan menggunakan kendali PI (Proportional Integral). Didapatkan nilai optimal pada kp=10 dan ki=30 pada kecepatan angin 12 m/s dengan settling time 3 sekon. Kata kunci : proportional, integral, generator induksi, turbin angin
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
