Latar belakang: Identifikasi dan deteksi dini keterlambatan perkembangan anak sampai usia 3 tahun membutuhkan alat uji penapisan yang sahih dan andal serta mudah diaplikasikan orangtua. Kesahihan dan keandalan ASQ-3 belum teruji di Indonesia sehingga ASQ-3 belum digunakan secara luas sebagai alat uji penapisan perkembangan anak. Tujuan: Mengetahui kesahihan dan keandalan ASQ-3 bahasa Indonesia sebagai alat uji penapisan keterlambatan perkembangan anak usia 24-36 bulan. Metode: Penelitian potong lintang ini dibagi menjadi 2 tahap. Tahap pertama yaitu adaptasi transkultural, modifikasi dan tranlasi kuesioner ASQ-3 versi orginal ke bahasa Indonesia. Tahap kedua, kuesioner bahasa Indonesia yang sudah final, diuji ke 30 subyek dari 5 kelompok umur (24,27,30,33,36 bulan). Uji kesahihan dengan menggunakan koefisien korelasi, uji keandalan dengan konsistensi internal dan keandalan inter-rater. Hasil: Uji kesahihan dengan koefisien korelasi kuat di domain komunikasi usia 24 bulan (0,908), domain motor kasar usia 24 bulan (0,860), domain motor kasar usia 36 bulan (0,865). Uji keandalan dengan Alpha Cronbach ialah baik (0,673-0,825) dengan keandalan inter-rater yang sangat baik (0,916). Kesimpulan: ASQ-3 bahasa Indonesia sahih dan andal sebagai alat uji penapisan keterlambatan perkembangan anak usia 24-36 bulan. ......Background: Identification of children with developmental disabilities is critical step in providing early intervention services. Ages and Stages Questionnaires third edition (ASQ-3), a parent-report questionnaires has been proven to be a valid and reliable screening test and good psychometric properties. This test has not been validated and standardized before in Indonesia. Aim: To provide the validated and reliability form of the Indonesian version of the Ages and Stages Questionnaires as an appropriate developmental screening tool for evaluation of 24-36 months Indonesian children's development. Method: Cross sectional study divided into two parts. First part included the adaptation, transcultural, and translation ASQ-3 original version to Indonesian version. Second part, final form of Indonesian ASQ-3 was performed for 30 children from 5 age groups (24,27,30,33,36 months). In order to determine validity of the questionnaires using correlation coefficient, and reliability was measured using internal consistency and intraclass correlation coefficient. Results: The validity determined by correlation coefficient was very good in communication area at 24 months age (0.908), gross motor at 24 months age (0.860), and gross motor at 36 months age (0.865). The reliability, determined by cronbach's alpha ranged from 0.673-0.825 and the inter-rater reliability was 0.916. Conclusion: The Indonesian version of the ASQ has appropriate validity and reliability for screening developmental disorders in 24 -36 months children in Indonesia.

Pasar e-commerce diproyeksikan akan terus bertumbuh hingga tahun 2020, pasar Indonesia termasuk didalamnya. Pertumbuhan tersebut dipicu oleh meningkatnya jumlah pengguna internet baik di dunia maupun di Indonesia. Namun seiring dengan meningkatnya pasar e-commerce di Indonesia, hal ini diikuti dengan menurunnya arus kunjungan ke toko ritel secara langsung. Pomona merupakan sebuah perusahaan adtech di Indonesia yang mencoba untuk mengembalikan arus kunjungan ke toko ritel tersebut. Pomona menggunakan platform mobile application sebagai alat untuk menjalankan bisnisnya. Akan tetapi menurut studi pendahuluan yang dilakukan pada penelitian ini, 75% responden mengatakan masih mengalami kendala ketika menggunakan aplikasi tersebut. Oleh karena itu diperlukan uji usability terhadap aplikasi ini untuk mengetahui seberapa mudah aplikasi mobile Pomona digu nakan. Penelitian ini menggunakan metode usability testing dengan menggunakan think aloud, after scenario questionnaire (ASQ), system usability scale (SUS), dan questionnaire for user interface satisfaction (QUIS) dalam mengolah data. Setelah mendapatkan hasil usability dari aplikasi Pomona, penelitian ini dilanjutkan dengan melakukan perbaikan rancangan user interface pada aplikasi tersebut dengan menggunakan pendekatan user centered design dan menggunakan 10 usability heuristics for user interface design serta Material Design sebagai literatur dalam melakukan perbaikan. ......The e-commerce market is projected to grow until 2020, including in Indonesian. This growth was triggered by the increasing number of internet users both in the world and in Indonesia. But along with the increasing e-commerce market in Indonesia, this was followed by a decline in the number of visits to the retail store. Pomona is an ad tech company in Indonesia that tries to increase the number of visits to the retail store. Pomona uses the mobile application platform to run its business. However, according to a preliminary study, 75% of respondents said they were still having problems when using the application. Therefore we need usability testing for this application to find out how easily the Pomona mobile application is used. This study uses the usability testing method with think aloud, after scenario questionnaire (ASQ), system usability scale (SUS), and questionnaire for user interface satisfaction (QUIS). After gathered the usability results from the Pomona application, this research was continued by making improvements to the user interface design of the application using the user-centered design approach and using 10 usability heuristics for user interface design and Material Design as literature in the making of usability improvements.
