UNS – Through the funding of the Independent Learning Grant and Campus Merdeka Learning (MBKM), the Baskara Team from Universitas Sebelas Maret (UNS) Surakarta has successfully created a charging dock station for electric scooters. Previously, the Baskara Team also innovated technology through MBKM grant funding. This technological innovation was an electric scooter equipped with a Global Positioning System (GPS) and Radio Frequency Identification (RFID) tag system.

The Baskara Team was guided by Agus Ramelan, S.Pd., M.T., and consisted of 10 other students. Hammam Al-Choiri from the Department of Electrical Engineering, Faculty of Engineering (FT), served as the team leader. The other nine members were Adhitya Fajar Rachmadi, Asri Aziziyah, Bagas Setyawan, Dian Eka Febriyanti Adz Zahra, Hendrawan Purnomoaji, Immanuel Satrio Putro Sulistyoaji, Mario Alfandi Wirawan, Muhammad Sandya Rafiyatna, and Muhammad Iksan Bima Aria Pratama. The Baskara Team designed the Smart Solar Change Controller Solar Panel System and Internet of Things (IoT)-based Charger Dock system for the electric scooter they created.

The scooter, which has a conventional charging system, is named ESCOMAR. To charge the ESCOMAR's battery, users only need to plug the charger into the power port of the scooter. To make the charging process more environmentally friendly, the Baskara Team also designed a dedicated Charger Dock, making ESCOMAR an emission-free vehicle. The Charger Dock also offers a unique advantage: scooter users do not need to connect the charging cable to initiate battery charging. They only need to place the scooter on the Charger Dock and press the on button to start the charging process.

In the MBKM Grant program for the period of September 2022 to January 2023, 100 selected titles were chosen. These selected titles were eligible to receive MBKM grant funding. It is hoped that through this MBKM Grant program, all outstanding innovations from study programs (prodi) and students can be realized. This also serves as evidence of the implementation of support from the UNS Directorate of Academic Reputation and Student Affairs for independent learning activities through MBKM grant funding.

"The details of this charger dock use a 100 Wp PV with an output of 12V/5A and storage in a 12V/44Ah battery pack. These specifications make the charger dock environmentally friendly," said Agus Ramelan, as quoted from elektro.ft.uns.ac.id, on Tuesday (2/7/2023).

The power of the battery charging on the scooter uses a 12V supply with an output current of 5A from the battery supply. The charging power will be increased to 43V with an input of 3A to the scooter's battery.
