As a Project Manager and Engineer with BUMA and the Delta Dunia Group, I have been with the organisation (including the previous ownership of the Australian Operation) since 2013.

Starting as a casual engineer whilst finishing my engineering and business degrees I was drawn in by the positive atmosphere and extensive development opportunities; I quickly realized the value of the graduate program. This initiative allowed me to hone my technical and mining skills prior to graduation, setting a strong foundation for my career.

Valuing staff development and developing depth of experience is a key philosophy at BUMA and in my career I have been fortunate to work on site in a number of different mines and to have learnt skills like the operation of the 220t Komatsu 830E haul trucks. This hands-on experience was instrumental in my professional growth and added immensely to my development.

My career has been both challenging and rewarding. As a production supervisor, I successfully oversaw crew safety and production, reflecting the company’s commitment to rewarding hard work, loyalty, and contribution. In 2020, with the support of my colleagues, I passed the challenging QLD Site Senior Executive (SSE) exam, further enhancing my expertise.

More recently I have had the opportunity to visit Indonesia and Singapore as part of the Delta Explorer program. This high quality future looking program provides strategic understanding and leadership across the Delta Dunia business and allowed me to meet colleagues and share perspectives on our  goals and vision for the future.

Throughout my time with BUMA, I have embraced opportunities and thoroughly enjoyed the challenge. I look forward to what the future may bring.

11 years with BUMA

I've embarked on an incredible ten-year journey with Delta Dunia Group, commencing with the BUMA Management Development Program within the Engineering Department. During my seven years at the job site, I witnessed the company's unwavering commitment to safety, teamwork, and excellence.

Today, I'm an integral part of Bukit Teknologi Digital (BTech), a subsidiary dedicated to pioneering digital technology and driving the transformation of the mining industry. As a Product Manager in Asset Management, I enthusiastically undertake the role of identifying product potential, outlining specifications, and crafting delivery schedules to provide maximum value to our customers. It's an opportunity I hadn't even fathomed before

Looking ahead, I eagerly anticipate continuing to be a part of Delta Dunia Group's evolution into one of the world's leading companies. It's an inspiring journey, and I'm dedicated to helping pave the way for a brighter future in mining and digital transformation.

11 years with BUMA & BTech

BUMA has been my first and only professional home. My journey began with the BUMA Management Development Program, where I had the privilege of wearing many hats and overseeing a diverse range of projects. From crafting effective maintenance plans, providing on-site maintenance support, and developing maintenance strategies, to budgeting and meticulous asset management, I've been fortunate to contribute to various facets of our operations. Calculating Repair & Maintenance budgets for new project tenders has been both challenging and rewarding. Every task is infused with my passion for our company, its leadership, and its people. I want to keep on growing together with BUMA.

5 years with BUMA and Delta Dunia Group

At Delta Dunia Group, I've discovered a world of endless possibilities beyond my comfort zone. The turning point arrived when I joined BIRU, a subsidiary with a profound vision—a vision to create a lasting, positive impact on the environment and society through competency-based industrial education for the Indonesian generation. This transformation marked a significant shift from my previous role of 12 years in heavy equipment maintenance at BUMA.

The opportunity to contribute to both the environment and society has presented its fair share of challenges for me and my team. Together, we've embarked on the mission to ensure that through BIRU, Delta Dunia Group not only thrives but also becomes a driving force for the betterment of communities in Indonesia. I hope to witness the Delta Dunia Group evolve into a globally renowned green company, inspiring a brighter, more sustainable future.

13 years with BUMA and BIRU

In 1989, I left East Nusa Tenggara for Mamuju in search of work and found my path with BUMA, a company initially focused on plantations before entering the mining industry. I have witnessed numerous changes and growth expansion over my 34-year with BUMA, However, two things have always remained constant throughout the years: a commitment to the safety of the employees and their families, which has always been a top priority, and a deep sense of unity among us.

BUMA's evolution has brought extensive advancements to its employees through technology, facilities, and more. I hold hope that BUMA's spirit of innovation and growth will continue, not only for the company but also for the success of our extended BUMA family.
