Uji Validitas dan Reliabilitas Instrumen Penelitian Kuantitatif

Abstract

The research instrument is a tool used to collect data or measure objects of a research variable. To obtain the correct data for the conclusion that is in accordance with the actual situation, then required a valid instrument and consistent and appropriate in providing data of research result. Instrument reliability tests to include test-retest, equivalent, and internal consistency. Internal consistency tests have several testing techniques depending on the type of instrument. Testing techniques included split half test, KR 20, KR 21, and Alfa Cronbach. The value of the validity and reliability of an instrument is influenced by the measured subject, the instrument user, and the instrument itself. Sehinggga, validity and reliability must always be tested before the instrument is used.

Accuracy Implementation of Medical Record Management Information System with Waterfall Design System and ISO 9126

“…The varia 9126 is between functionality and reliability. The validity test is used to find out how valid the questions or statements are given to respondents to get something [16] techniques used to measure validity is the Pearson Product Moment technique the significance test is carried out with the criteria using at the 0.05 significance level with a 2-sided test. If the value is positive and ℎ ≥ then the item is declared val and if ℎ < then the item is declared invalid.…”

“…Security: The ability of the software to prevent unwanted access, against intruders (hackers) and authorization to modify Interoperability: The ability of the software to interact with one or more specific systems Compliance: The ability of the software to meet standards and requirements according to applicable regulations Maturity: The ability of the software to avoid failures as a result of errors in the software Fault tolerance: The ability of the software to maintain its performance in the event of a software glitch Recoverability: The ability of the software to rebuild performance levels in the event of system failure, including data and network connections ; Article no. AJRCOS.60968 The validity test is used to find out how valid the questions or statements are given to [16]. One of the techniques used to measure validity is the Pearson Product Moment technique [17].…”

“…A validity test was used to determine whether the research instrument items were valid or not by showing the extent to which a measuring instrument measures precisely the concept to be measured [27]. Data collection in this study used questionnaires.…”

Skala Pengukuran Karakter Adil: Salah Satu Instrumen sebagai Piranti BADRANAYA (Board-game Karakter Konselor Multibudaya)

“…Uji validitas dan reliabilitas dalam sebuah penelitian penting untuk dilaksanakan, hal ini diperkuat dengan pendapat dariArifin (2017) yang mengatakan bahwa validitas, reliabilitas, tingkat kesukaran, daya pembeda dan pengecoh (distraktor) merupakan hal yang penting yang harus diperhatikan oleh peneliti agar instrumen yang dibuat menjadi baik, sehingga bisa digunakan dalam menghasilkan data yang baik pula. Selain itu, pendapat lain juga mengatakan bahwa instrumen penelitian merupakan alat yang digunakan untuk mengukur data objek dari variabel penelitian, kualitas dari sebuah instrumen dipengaruhi oleh pengukuran subjek, pengguna instrumen dan instrumen itu sendiri, sehingga uji validitas dan reliabilitas harus dilakukan sebelum instrumen itu digunakan(Yusup, 2018). Berdasarkan hasil dari penelitian dan pendapat di atas maka dapat disimpulkan bahwa uji validitas dan reliabilitas yang dilakukan pada skala pengukuran Karakter Adil adalah suatu tindakan yang tepat dalam tahap penelitian ini, karena kualitas dari skala pengukuran ini salah satunya tergantung dari hasil uji validitas dan reliabilitas instrumen.SIMPULANBerdasarkan pemaparan di atas dapat diketahui bahwa pengembangan media BK bernama BADRANAYA ini menggunakan tahapan penelitian dan pengembangan Borg & Gall 1983 yang dimodifikasi sesuai kebutuhan penelitian menjadi 6 langkah Dimana tahap penelitian saat ini memasuki tahap ketiga yaitu Pengembangan Draft Awal Produk dimana salah satunya adalah penyusunan instrumen berupa Skala Pengukuran Karakter Adil.…”
