Laksana Bodywork Focuses on City Bus Development: Introducing the Nucleus 6

Jakarta - PT Laksana Bus Manufaktur (Karoseri Laksana) launched its latest model to demonstrate its commitment to sustainable transportation in Indonesia on Tuesday (July 15, 2025). The 6th Generation Nucleus medium bus (Nucleus 6) is a bus model from Karoseri Laksana that caters to the city bus segment. Along with the launch of the Nucleus 6, Karoseri Laksana showcased its city bus products based on electric bus chassis and introduced its ongoing product Research and Development Center.

"The launch of the Nucleus 6 demonstrates our capability to produce electric buses domestically, supported by collaborations with strategic partners such as VKTR, Hyundai, Skywell, and other brands. This demonstrates that the domestic industry is capable of independently and sustainably addressing the challenges of electrifying public transportation," said Stefan Arman, Technical Director of PT Laksana Bus Manufaktur, at the launch of the Nucleus-6 electric bus in Ungaran, Semarang Regency, Central Java.

Stefan explained that Karoseri Laksana is committed to producing buses with a continuously improving Domestic Component Level (TKDN). He stated that the company is demonstrating its commitment to reducing dependence on imported components with the launch of this latest model.

Karoseri Laksana has developed a research and development center to produce bus designs that adapt to user needs. With a sleeker and more aerodynamic design, the Nucleus 6 features the latest electrical technology that supports high energy efficiency and a longer service life.

The Nucleus 6 is designed to meet the needs of services such as school buses, airport shuttles, and employee transportation. It is also designed to be accessible to passengers with disabilities, with features like ramps, priority seating, and easy-to-reach handrails. The simple design makes the bus easy to maneuver in areas with limited road access while prioritizing passenger comfort and safety.

During the launch, the Karoseri Laksana development team presented aspects of the frame design, materials, and maneuverability. Specifically for electric buses, Karoseri Laksana also considered the electrical load for the electrical system by analyzing the load and preparing electrical system diagrams.

The Laksana Carrosersi development team also explained the various structural standards for its bus bodies. These include the UN ECE R66 standard for the Rollover Test, the UN ECE R29 standard for the Impact Test, the UN ECE 93 standard for the Front Underrun Protection Device, the UN 107 standard for the Stability Test, and the UN ECE R80 standard for the Seat Accordance & Stress Test.

"We hope that with the presence of this research and development center, and strategic synergy with electric bus manufacturers in Indonesia, such as VKTR in Magelang, we will not only produce buses but also build an integrated electric vehicle ecosystem, from manufacturing, distribution, to after-sales service. This is part of our grand vision to accelerate the green transportation transformation in Indonesia, in line with the national emission reduction target," Stefan emphasized.

Laksana Carrosersi, which is celebrating its 48th anniversary this year, has produced various models of medium-sized and large buses for various needs. These include school buses, employee buses, city buses, tourist buses, and long-distance intercity and interprovincial buses.

Specifically for city buses, Karoseri Laksana has been trusted as one of the dominant suppliers for the Transjakarta bus fleet. Karoseri Laksana also exports its buses to Fiji, Timor Leste, Bangladesh, Laos, and Sri Lanka, producing 1,200-1,500 units annually.
