Abstract

Mode kompensasi yang berbeda memiliki sensitivitas berbeda terhadap perubahan koefisien kopling sistem wirelss power transfer (WPT). Nilai puncak arus kumparan transmisi berdasarkan mode kompensasi double LCC berubah relatif sedikit ketika beban berubah. Rangkaian double LCC memiliki efek penyaringan dan kehilangan siaga yang rendah saat dinamis sehingga mampu memberikan toleransi misalignment dan meningkatkan efisiensi transfer daya. Perancangan driver wirelss power transfer menggunakan topologi kompensasi induktor-kapasitor-kapasitor (LCC) yang diterapkan pada sisi transmitter dan receiver. Nilai induktor dan kapasitor dianalisa untuk mendapatkan komponen yang sesuai. Kumparan pemancar dan penerima dengan nilai induktansi dan resistansi yang beragam diuji dan dianalisa untuk mendapatkan output daya serta efisiensi yang optimal. Frekuensi 20 kHz digunakan untuk membangkitkan arus bolak balik pada rangkaian inverter. Pada jarak kumparan terdekat 0 cm dengan suplai tegangan 12 V DC mampu mentransmisikan tegangan sebesar 7,55 V DC dan arus sebesar 0,67 mA. Daya yang dihasilkan sebesar 5,06 watt. Efisiensi daya yang dihasilkan dengan menggunakan kompensasi LCC sebesar 44,15 %. Kumparan Tx dan Rx memiliki jumlah lilitan yang sama yaitu 100 dengan bentuk spiral persegi.

Abstract

Jakarta Kini (JAKI) is a digital service innovation initiated by the Provincial Government of Jakarta through the Jakarta Smart City program as an effort to apply information and communication technology in public administration. This study aims to analyze public perceptions of the effectiveness of JAKI in improving the quality and accessibility of public services in Jakarta. The research employs a descriptive qualitative approach with secondary document analysis derived from official reports, academic publications, and application performance data. JAKI is positioned as a regional model of smart governance that integrates multiple public services into a single digital platform. Unlike previous studies that mainly focused on technological aspects or user satisfaction, this study highlights the interconnection between government digital innovation and citizen participation within a data-driven public service ecosystem. The findings indicate that JAKI plays a substantial role in accelerating citizen reporting, expanding service accessibility, and strengthening participatory governance in digital administration. Early features such as JakLapor, JakRespons, JakPantau, and JakWarta serve as key foundations for two-way communication between the government and citizens. Meanwhile, new developments such as the Health Facility Queue Service, JKN Mobile Integration, Early Warning Notifications, and JakCare further enhance the platform’s role as an integrated digital service hub. Nevertheless, JAKI’s implementation remains suboptimal due to challenges related to uneven digital literacy, limited technological infrastructure, and data protection issues.
