Abstract

This study aims to analyze the effect of solar panel use on household electricity cost savings. The research adopts a quantitative approach involving 160 respondents who are household users of solar panel systems. Data were collected through a structured questionnaire using a Likert scale to measure respondents’ perceptions regarding solar panel utilization and its impact on electricity expenses. The collected data were analyzed using SPSS version 25, including validity testing, reliability testing, descriptive statistics, and simple linear regression analysis. The results show that solar panel use has a positive and significant effect on household electricity cost savings, with a regression coefficient of 0.705 and a significance value of 0.000, which is below the threshold of 0.05. The coefficient of determination indicates that solar panel utilization explains 37.1% of the variation in electricity cost savings, while the remaining percentage is influenced by other factors. The findings suggest that households that adopt solar energy systems tend to experience lower monthly electricity costs due to reduced dependence on conventional electricity supplied by the public power grid. In addition to financial benefits, solar energy also contributes to environmentally sustainable energy consumption. Therefore, the adoption of solar panel technology can be considered a practical solution for improving household energy efficiency and reducing electricity expenditures. The results of this study provide useful insights for policymakers, energy providers, and households in promoting the wider adoption of renewable energy technologies.

Abstract

Pintu geser otomatis berfungsi untuk membuka dan menutup secara otomatis ketika mendeteksi keberadaan seseorang di dekat pintu. Penggunaan pintu ini dapat meningkatkan kenyamanan dan keamanan. Sistem kontrol pintu geser otomatis harus dirancang dengan cermat untuk mewujudkan fungsi yang optimal. Pada penelitian ini dirancang pintu geser otomatis menggunakan metode perancangan FSM (Finite State Machine). Pengenalan wajah digunakan untuk membuka pintu. Penggerak buka tutup pintu yang digunakan adalah motor stepper. Pintu geser otomatis dikendalikan menggunakan mikrokontroler Arduino UNO dan limit switch. Sensor PIR ditambahkan sebagai fitur safety pada pintu. Hasil yang didapatkan dari pengujian sensor PIR diketahui bahwa sensor PIR dapar memdeteksi keberadaan manusia hingga 2,5 meter. Pada pengujian fungsional didapatkan bahwa setiap transisi state dari metode perancangan FSM berhasil dilakukan sehingga sistem pintu otomatis bekerja dengan baik.

Abstract

With the fast development of the digital world, the Internet of Things (IoT) has become an important element in the research domain nowadays. This research seeks to explore how the IoT literature developed from 2010 to 2026 via the bibliometric analysis of publications in Scopus databases. Using VOSviewer software to analyze co-authorship network, citation network, and keywords co-occurrence network, this study is intended to illustrate the structural features of the IoT literature in terms of its intellectural, social, and conceptual aspects. The findings indicate that IoT studies are characterized by close relations between researchers around the world, resulting in several major knowledge diffusion centers. In the context of citations analysis, the major sources not only contribute to technological development but also address issues like the sustainable environment, digital governance, and socio-economic transformations. As regards keywords co-occurrence analysis, the main groups of IoT research are smart environments, technology, engineering, and socio-technical studies. Overlay and density maps point out that there is a change in time concerning the focus of research towards more advanced concepts in the field, such as artificial intelligence in IoT, big data analysis, industry 4.0, and sustainable development. It can be concluded that IoT research is becoming more mature and multidisciplinary in nature, focusing more on addressing issues on a global scale. This paper will contribute to the existing literature on IoT research through a thorough systematic and long-term analysis of IoT studies.
