Mr Wisnu Sanjaya presently holds the position of General Manager of Gunung Putri Graha Mas, having first joined the company in 2006. Mr Sanjaya’s expertise in the manufacture of fibreglass reinforced plastic products is complemented by an international approach to business developed over the course of his studies at Seattle University in the United States.

Human Resources

As a labour intensive industry, human resources play a crucial role in fiberglass product manufacturing and the ability to successfully deliver large scale, customised products. Gunung Putri Graha Mas prides itself on its workforce and their capacity to achieve high levels of productivity as well as abide by stringent quality control measures. With nearly three decades of experience in building a highly competitive team, the company has extensive expertise in understanding the cultural nuances of the Indonesian workforce and thus how to effectively build a dynamic corporate culture that harnesses maximal productivity.

Gunung Putri Graha Mas is committed to the continuous improvement of its staff’s skills through training. To keep abreast of the latest processes and technologies, the company’s staff undergo comprehensive training in Japan and the US and are able to expand upon their knowledge of FRP via access to technical support from the American Composite Manufacturers Association (ACMA). In keeping with its goal of guaranteeing the utmost level of professionalism amongst employees, GPGM also encourages the development of soft-skills such as accountability and transparency through carefully-formulated management techniques and processes.

The company’s dedication to developing human resources and strong emphasis on establishing clear channels of communication between management, engineering and production has fostered an intimate, family-like atmosphere. Reciprocated loyalty between company and human resources has ensured both low employee turnover and an on-going accumulation of technical know-how and experience amongst workers, conducive to the production of consistently high quality fibreglass reinforced plastic goods. These attributes provide the foundations for the company’s on-going progress as well as for establishing further partnerships with international fiberglass producers entering the Indonesian market.

Innovative Materials

Gunung Putri Graha Mas

Gunung Putri Graha Mas’ long-standing experience in building materials and dedication to research and development is the unifying element across the group’s various brands and product lines as well as the driving force in its innovative approach. This led to the strategic shift towards FRP products as an alternative to metallic and naturally occurring materials.

Fiberglass reinforced plastic offers greater environmental sustainability in terms of the procurement of the materials as well as in the production process. In addition, the material’s longevity and corrosion-resistance mitigates the release of harmful powdery, decomposed plastic which commonly occurs with PVA and PVC plastic products.

Gunung Putri Graha Mas’ forward-thinking approach to business encourages employees to seek out new applications for existing materials, and also sets in motion a continuous company-wide drive to refine the properties of existing applications. GPGM forecasts that FRP will soon be applied on a large scale in Indonesia in the construction of water treatment facilities, sewage systems and product transportation. Such FRP applications are already used in developed markets and will undoubtedly play a central part in the development of Indonesia’s much needed public utilities infrastructure.

With an abundance of experience in manufacturing FRP pipes and tanks for these types of projects abroad, Gunung Putri Graha Mas is primed to offer its cutting-edge fibreglass goods to the domestic market and be part of realising the national goal of environmentally sustainable development.
