Pengukuran Kepuasan Pengguna Situs Web Dengan Metode End User Computing Satisfaction (EUCS)

This research conducted to determine the level of user satisfaction of Universal University website so that the website administrator can get an overview of the level of user satisfaction as well as future evaluation materials. Measurement of user satisfaction used End User Computing Satisfaction (EUCS) method. Measure of user satisfaction are two methods, End User Computing Satisfaction (EUCS) and User Information Satisfaction (UIS). Based on the research of Seddon & Yip [4] who conducted a comparison between the EUCS and UIS methods it was found that the EUCS method was more useful than the UIS method. The variables in this research are content, accuracy, format, ease of use, and timeliness. The samples in this study collected from 168 respondents consisting of 3 staffs, 17 lecturers and 148 students. The data collection used a closed questionnaire consisting of 13 question for the five variables being studied. From the data obtained, concluded that the overall level of user satisfaction is in the average value of 2.64 at level 3 (neutral), which means that according to the general respondents’ perception, Universal University website not said satisfactory but also not disappointing. Variables that have assessed as good enough are accuracy and ease of use, while for content, format, and timeliness are still considered for more improvement and developed again. Keywords: user, satisfaction, eucs, websit

JENIS PENALARAN ILMIAH APA YANG DIGUNAKAN MAHASISWA DALAM MENYELESAIKAN PERMASALAHAN SUHU DAN KALOR?: STUDI PADA PRAKTIKUM FISIKA UMUM: Indonesia

ABSTRAK   Salah satu kemampuan yang harus dimiliki oleh mahasiswa calon guru adalah kemampuan penalaran ilmiah. Meskipun demikian, kemampuan ini masih belum dilatihkan. Penelitian ini bertujuan untuk menganalisis kemampuan penalaran ilmiah mahasiswa calon guru pada materi suhu dan kalor. Penelitian ini merupakan studi deskriptif dengan melibatkan 57 mahasiswa yang mengikuti perkuliahan fisika umum di UIN Syarif Hidayatullah Jakarta tahun ajaran 2021/2022 selama empat bulan. Berbeda dengan kegiatan praktikum yang biasanya verifikatif, perkuliahan ini menggunakan modul Higher Order Thinking Laboratory (HOT-LAB) yang memuat Real World Problem pada tahap pra-praktikum. Hasil penelitian menunjukkan bahwa pola penalaran ilmiah mahasiswa adalah penalaran probabilistik sebesar 84% yang terdiri dari 56% pada level 2 dimana merupakan kemampuan mahasiswa menjelaskan secara kualitatif, dan 44% pada level 3 dimana kemampuan mahasiswa menjelaskan secara kuantitatif. Sedangkan 16% pola penalaran mahasiswa adalah penalaran korelasi. Sehingga dapat disimpulkan bahwa sebagian besar pola penalaran ilmiah mahasiswa calon guru dalam menyelesaikan permasalahan yang diberikan adalah penalaran probabilistik.   Kata  kunci: Kalorimeter, Penalaran Ilmiah, Suhu dan Kalor,   ABSTRACT   The capacity for scientific reasoning is one of the talents that potential teacher candidates must possess. But this talent is still untrained. The purpose of this study is to evaluate prospective teacher students' capacity for scientific reasoning with regard to temperature and heat-related. This research is a descriptive study involving 57 students who attend general physics lectures at UIN Syarif Hidayatullah Jakarta for the academic year 2021/2022 for four months. Different from practicum activities which are usually verified, this lecture uses the Higher Order Thinking Laboratory (HOT-LAB) module which contains Real World Problems at the pre-practicum stage. The results showed that the pattern of students' scientific reasoning was probabilistic reasoning by 84%, This comprises of 44% at level 3 where the student's quantitative explanation ability is assessed, and 56% at level 2 where the student's ability to explain qualitatively is assessed. While 16% of students' reasoning patterns are correlational reasoning. Therefore, it can be stated that the majority of prospective teachers' students' scientific reasoning techniques for addressing temperature and heat-related problems are probabilistic reasoning.   Keywords: calorimeter, scientific reasoning, temperature and heat-related

Sistem Kontrol dan Monitor Kadar Salinitas Air Tambak Berbasis IoT LoRa

Pada saat ini sering terjadi kematian ikan yang disebabkan oleh kadar salinitas yang tinggi pada pembudidayaan ikan di tambak. Salinitas merupakan sebuah tingkat kadar garam yang terlarut pada air. Kadar salinitas yang tidak normal dapat membuat pertumbuhan ikan melambat. Oleh karena itu, para pembudidaya ikan perlu melakukan sebuah pengamatan di tambak agar kualitas air sesuai dengan kebutuhan ikan yang dibudidayakan. Pemantauan ini harus dilakukan setiap hari sehingga akan menyulitkan bagi pembudidaya ikan, terlebih jika jarak tambak dari perumahan yang cukup jauh. Oleh karena itu maka diperlukan suatu alat yang bisa memantau maupun mengontrol kadar salinitas dari jarak yang jauh tanpa perlu datang ke lokasi tambak. Sistem yang digunakan untuk penelitian ini berbasis IoT dimana semua pemantauan secara real time akan membutuhkan internet. IoT yang digunakan pada penelitian ini adalah IoT LoRa dan nodeMCU esp8266. Pemantauan dan pengontrolannya dilakukan dengan membaca sensor salinitas air tambak dengan menggunakan Sensor Total Dissolved Solid (TDS). Data pembacaan sensor TDS diolah oleh sebuah microcontroller Arduino Uno. LoRa Transmitter akan mengirimkan datanya ke LoRa Receiver. Setelah data diterima di receiver data dikirimkan melalui Node MCUesp8266 ke aplikasi Blynk yang ada di perangkat smartphone. Sedangkan sistem kontrolnya menggunakan kontrol Proportional Integral Derivative (PID) untuk mengatur relay. Relay ini mengatur lama bukaan valve untuk membuka atau menutup, menambah maupun mengurangi kadar salinitas pada air. Pengujian sensor salinitas dilakukan di berbagai kadar salinitas air mulai dari 0 ppt sampai 40 ppt. Dari hasil percobaan menunjukkan bahwa sensor TDS ini mampu membacanya dengan baik. Sedangkan LoRa mampu mengirimkan datanya dengan baik pada jarak kurang lebih 600 meter. Pada pengujian keseluruhan sistem di tambak didapatkan nilai standar deviasi eror ketika kondisi mulai stabil sebesar 0,24 pp

Kinetic Freeze-out and Radial Flow in 11.6 A GeV Au+Au Collisions

We study the kinetic freeze-out conditions of hadrons in Au+Au collisions at 11.6 A GeV/c using different parametrizations of an expanding thermal fireball. We take into account the available double differential momentum spectra of a variety of particle species, covering a large fraction of the total momentum space. The overall fit to the data is very good and indicates a relatively low kinetic freeze-out temperature of about 90 MeV with an average transverse expansion velocity at midrapidity of about 0.5 c.Comment: 5 pages ReVTeX, incl. 3 figures and 2 tables.

Midterm outcome of total knee arthroplasty in East Coast population of Hospital Tengku Ampuan Afzan Kuantan

Introduction: Total knee replacement (TKR) is an excellent advancement in medical treatment which gives good joint function and pain relief for degenerative diseases of joint since it was introduced in Malaysia since 1970. The purpose of this study was to evaluate the midterm functional outcome of patients undergone TKR using the NexGen LPS Flex prosthesis between January 2005 until April 2006 in primary osteoarthritis patients in our local east coast population. Materials and Methods: Forty six patients, 87% female (n=40) and 13% male (n=6), aged 54 to 81 (mean, 69±5.69) years underwent primary TKR using the hi-flex knee prosthesis (Zimmer) performed by two different surgeons were followed up for a minimal of five years. All used the same technique of surgery, medial parapatellar incision, cruciate substitute and cemented. Assesment were made based on the quality of life outcome score (SF-36) and the Oxford-12 knee scoring system questionnaires. Results: Oxford-12 revealed that patients had mild problems in terms of function and pain with the average function and pain score of 14.35±4.21 and 9.28±3.01 compared to a maximum possible score of 35 and 25 respectively. For eight health domains of SF-36, patients had the highest score (i.e. good health) for role emotional (RE), followed by mental health (MH), and social functioning (SF). This resulted in a higher score for mental component summary (MCS) than physical component summary (PCS). Since a low score of Oxford-12 indicates a better state of health compared to high score for SF-36, negative correlation between them was expected. Conclusion: The NexGen LPS-Flex TKR had good midterm functional outcome. Overall, TKR were found to be effective in terms of improvement in health-related quality-of-life dimensions
