Abstract

Nowadays, Smart Home technology has been widely reached by society and utilized by most people, from the upper to the middle class, with various brands and products including its features. Smart Home Universitas Pendidikan Indonesia (SH-UPI) is a commercial smart home platform, a new player in this technology business. UPI Academics developed the SH-UPI platform; they successfully commercialized a smart LED Bulb (RGB lamp). The product is managed by a particular Android application, i.e., SH-UPI Apps; it can be downloaded on the Play Store or the official website. However, based on information from the developer, this application has yet to consider good UI/UX aspects during production. Therefore, it is highly necessary to redesign the SH-UPI application to give users a more comfortable (user-friendly) and is competitive against other competitors. The SH-UPI Apps was redesigned using the Design Thinking framework. This method comprises five stages: Empathize, Define, Ideate, Prototype, and Test. This preliminary study focuses on the Empathize, Define, Ideate, and Prototype stages. The results reveal that the Emphatize stage has been carried out well, which concludes that the application needs to be redesigned to improve the user experience’s quality. A mock-up for the new SH-UPI Apps version has been introduced in the Define to Ideate stages. The results of this study can be used as a reference for developing SH-UPI Apps with much better UI/UX. Afterward, the study will continue to further stages: Test.

Abstract

Rangkaian jembatan Wheatstone merupakan salah satu konfigurasi rangkaian resistor yang berfungsi untuk mengukur perubahan resistansi (hambatan) yang sangat kecil, dan telah banyak digunakan pada rangkaian sensor. Rangkaian ini disusun seperti belah ketupat, sedikitnya empat buah resistor (R1, R2, R3, R4), dimana salah satunya merupakan resistor tidak tetap (R3) yang biasanya menggunakan variable Resistor. Kemudian, salah satunya lagi merupakan resistor yang dicari nilai resistansinya (R4). Penelitian ini bertujuan untuk mengeksplorasi rangkaian jembatan Wheatstone dengan tiga skenario. Pertama, yaitu pencarian salah satu nilai resistor (R4) yang tepat saat keadaan balance, atau saat arus yang mengalir di titik AB sama dengan Nol (IAB sama dengan 0 A). Kedua, mengukur tegangan jembatan Wheatstone (VAB) dengan nilai resistor yang bervariasi. Ketiga, mencari salah satu nilai resistor (R4), nilai hambatan pengganti dari semua hambatan (REq) saat keadaan balance, dan arus total yang mengalir (ITotal) pada rangkaian jembatan Wheatstone ketika VAB sama dengan 0 Volt. Analisis memanfaatkan tiga buah simulator offline, yaitu Circuit Wizard v.1.15, Proteus v.8.5, dan Multisim v.14.0. Kemudian hasil simulasi ketiganya dibandingkan dengan perhitungan teoretis. Hasil simulasi dari ketiga simulator tersebut membuktikan bahwa nilai arus dan tegangan pada rangkaian Wheatstone telah sesuai dengan perhitungan teori, dimana IAB sama dengan 0A dan VAB sama dengan 0 V apabila keadaan seimbang. Dalam keadaan tidak setimbang, maka akan ada arus yang mengalir dari titik A ke titik B sehingga terdapat beda potensial, dimana nilai beda potensial ini sama dengan VA - VB. Artikel ini juga mengkaji performansi dan trade-off dari ketiga simulator tersebut saat eksperimen menggunakan rangkaian jembatan Wheatstone berdasarkan pengalaman (experience) langsung dalam sudut pandang peneliti.

Abstract

Software Define Networking (SDN) adalah salah satu perkembangan teknologi di bidang jaringan yang memisahkan control plane dengan data plane. SDN dapat diterapkan diberbagai topologi. Penelitian ini bertujuan untuk mengetahui dan menganalisis performa berbagai topologi jaringan berbasis SDN dengan Controller POX. Penelitian ini mengunakan metode Research and Development, yang diujikan dengan skala terbatas. Parameter pengujian yang dilakukan adalah delay, dan jitter. Dari hasil penelitian didapatkan hasil bahwa topologi linear, dan star memiliki performa yang sama.Akan tetapi topologi linear menjadi model topologi yang ideal dan lebih efisien karena memiliki jitter yang lebih kecil atau rendah dari semua topologi yang ada dari data penelitian ini. Diharapkan dari hasil penelitian ini bisa menjadikan gambaran bagi pembaca ataupun teknisi dalam memilih topologi saat membangun jaringan yang akan d rancang

Abstract

The rise of smart home technology has significantly impacted people’s behavior and lifestyle, especially when controlling household electronics remotely. Smart homes have become increasingly commoditized in the last decades, resulting in several vendors offering various commercial products and their variants. Universitas Pendidikan Indonesia (UPI) has created the smart home platform “SH-UPI,” which includes the Smart LED Bulb RGB. The platform’s mobile app can be downloaded from the Play Store or the official website (www.sh-upi.com). The SH-UPI is one of Indonesia's leading smart homes that adopted Internet-of-Things (IoT). However, customers have reported issues with the app’s user interface (UI) and user experience (UX), prompting a redesign to address these concerns and stay competitive. This study employs the design thinking method of empathizing, defining, imagining, prototyping, and testing. The define stage to prototype stage resulted in a newly designed prototype for the SH-UPI app. Testing involved evaluating the prototype using metrics like the User Experience Questionnaire (UEQ) and System Usability Scale (SUS). The test results showed an increase in the UEQ parameter value, exceeding the initial average scores of -0.8 to 0.8. Additionally, there was an improvement compared to benchmark scores, which initially ranged from below average to poor but now range from above average to excellent. The SUS score also improved, rising from 59.75 (grade D) to 83.625 (grade A). The findings of this study can be a valuable resource for developing SH-UPI apps with significantly enhanced UI/UX.
