Berlian Group, Inc., operating through its Bukit Berlian division, is a palm oil producer managing over 38,700 hectares of plantations across multiple provinces, including Palu, Gorontalo, Manado, and Maluku Utara. The private company is based in San Marcos, CA. The company holds permits for more than 85,000 hectares and focuses on sustainable development that balances economic and social benefits for local communities while minimizing environmental impact. Bukit Berlian emphasizes good agricultural practices, transparency, accountability, and quality improvement. The company sources palm oil seeds from domestic and international gardens, cultivates seedlings in nurseries, and provides intensive care during the early years to ensure optimal yields over a 25-year production cycle. Harvesting targets fresh fruit bunches at peak ripeness, with nearby mills processing the fruit within 24 hours to maintain oil quality and efficiency. Milling operations extract crude palm oil and palm kernel while recycling waste as fertilizer, and capacity is monitored to support production growth.
