Differences Between TKBT 1 and TKBT 2: A Complete Comparison of Competence, Responsibilities, and Incentives

According to data from the Indonesian Ministry of Manpower, about 30% of fatal workplace accidents in Indonesia are caused by falls from height, with approximately 850 cases reported in 2024. The High-Rise Building Worker (TKBT) certification, regulated under Ministry of Manpower Regulation No. 9 of 2016, is key to minimizing these risks.

TKBT training has two certification levels that reflect differences in competence and responsibility. This article explores in depth the distinctions between TKBT 1 and TKBT 2, covering skills, responsibilities, safety standards, salaries, and training.

What Is TKBT?

High-Rise Building Worker (TKBT) refers to workers who perform tasks at height in construction, building maintenance, or other industries involving work above ground level with inherent risks. The TKBT certification aims to ensure that workers have adequate competence to work safely at height, in accordance with established safety standards.

This certification is important for reducing accident risks and improving compliance with Occupational Safety and Health (OSH) regulations. It also equips workers with relevant technical skills and understanding of safety procedures, use of personal protective equipment (PPE), and proper work techniques under various high-altitude conditions.

Comparison with International Standards

The TKBT certification corresponds to several international standards, although it emphasizes the conditions and regulations in Indonesia. Below is a brief comparison with international benchmarks:

Differences Between TKBT 1 and TKBT 2

Participant Requirements and Criteria

According to SKKNI KEP.351/MEN/XII/2015 on Professional, Scientific, and Technical Services, TKBT certification has two levels with different requirements:

TKBT 1

TKBT 1 is intended for workers using temporary work platforms such as gondolas or scaffolding. General requirements include:

• Education & Age: Minimum junior high school (SMP) or equivalent, at least 18 years old.
• Health: Physically fit, with a medical clearance stating no conditions that impair working at height.
• Supporting Documents: Valid ID, passport-style photo, and educational certificate.
• Work Experience: Not required—TKBT 1 is designed for those starting a career in height-safety work.

TKBT 2

TKBT 2 is for workers on fixed elevated platforms, such as roofs or permanent structures. In addition to all TKBT 1 criteria, requirements include:

• Work Experience: At least one year of relevant height-safety experience or successful completion of TKBT 1.
• Additional Documentation: Proof of experience (company letter or work log).
• Advanced Technical Skills: Ability to manage more complex risks and advanced safety procedures.

TKBT 1 focuses on fundamental height-safety principles, while TKBT 2 covers deeper theoretical content and more complex techniques. The two-level system aligns worker competence with risk and task complexity, ensuring each individual meets appropriate safety standards.

Comparison by Major Aspects

The differences between TKBT 1 and TKBT 2 go beyond skill level to include job responsibilities, safety standards, career paths, and incentives. Key comparisons include:

Skill and Competence Levels

• TKBT 1 (Basic Level): Workers gain foundational knowledge of safety and technical skills for height work, including PPE use, basic equipment procedures, and hazard identification.
• TKBT 2 (Advanced Level): Workers develop more complex skills to manage higher-risk tasks and understand advanced safety protocols for working at height.

Responsibilities and Scope of Work

• TKBT 1: Responsible for basic operational tasks such as erecting scaffolding, using gondolas, and maintaining height-work equipment.
• TKBT 2: In addition to operational duties, oversees safety procedures, instructs team members, and enforces stricter OSH regulations.

Safety Standards

• TKBT 1: Standard safety requirements include correct PPE use, basic risk control, and emergency evacuation procedures.
• TKBT 2: Implements stricter standards, including detailed risk mitigation, advanced fall‐protection systems, and equipment inspection and maintenance.

Salary and Incentives

• TKBT 1: Entry-level compensation within industry norms for technical workers.
• TKBT 2: Higher compensation, including allowances and bonuses tied to supervisory and technical responsibilities.

Certification and Training

• TKBT 1: Certification via basic training covering theory and practical height-safety techniques and equipment use.
• TKBT 2: Requires more intensive training and prior experience. Evaluation includes theory exams, practical assessments, and on-site competency checks to ensure readiness for complex tasks.

Case Studies and Testimonials

Industry Implementation

TKBT 1 and TKBT 2 certifications are widely adopted in construction, building maintenance, and other high-altitude work. For example, in skyscraper projects, TKBT 1 workers install and maintain scaffolding, while TKBT 2 workers handle safety system installations on roofs and permanent structures.

Major construction firms now strictly require TKBT certification to ensure every worker has adequate safety knowledge before engaging in high-risk work.

Worker & Company Testimonials

Many TKBT participants report significant improvements in safety and skills:

Budi Santoso – Gondola Technician
“Before TKBT 1, I followed senior workers’ habits without fully understanding safety standards. I thought wearing a safety belt was enough. After the training, I learned correct PPE use, safe anchor points, and self‐rescue techniques. Now, I feel prepared and confident every time I ride the gondola—not just relying on experience but on proper knowledge.”

Andi Pratama – Scaffolding Worker
“I used to see colleagues erect scaffolding haphazardly. I didn’t know if my work met standards. TKBT 1 taught me that small mistakes can be fatal. Now I assemble scaffolding safely, secure my work area, and identify hazards. I even correct coworkers who skip procedures—this training truly saves lives.”

TKBT 2 Participant Testimonials

Rizky Maulana – Construction Supervisor
“As a supervisor, I relied on experience and instinct. TKBT 2 opened my eyes to technical details: risk assessments on permanent structures, PPE inspections, and emergency rope‐access rescue. Now I enforce safety standards rigorously, and there are no more unprotected workers. My team’s safety is top priority.”

Ratno Bayu – Roof Technician
“Roof work is risky, especially in bad weather. TKBT 2 taught me proper lifeline use, vulnerable roof‐structure identification, and colleague rescue techniques. The emergency rescue simulation was unforgettable—I now check every piece of equipment before climbing. This training changed how I work and boosted my confidence.”

Companies also see benefits: one major contractor reported a significant drop in accident rates after mandating TKBT certification. Compliance with safety regulations increased, making the company more competitive for large-scale projects.

Conclusion

Clear, structured certification standards aim to continuously improve safety in high-rise environments, reducing accidents and raising the quality of the workforce in construction and related industries.
