PEKANBARU - This is the dilemma faced by palm oil mills, which are still faced with ecological and environmental issues as key to waste management and regulatory compliance, particularly Government Regulation No. 28 of 2025 concerning Approval of Conformity of Spatial Utilization Activities (PKKPR). "Palm oil mills must pay attention to ecology and the environment." The palm oil mill of PT Mustika Agung Sawit Gemilang (MASG), which produces up to 60 tons of palm oil and palm kernel per hour in Gumanti Village, Peranap District, Inhu Regency, Riau, continues to improve its ecology, including changes in water, air, and noise quality," said Zulkifli AP S.Sos MM, Community Development Officer (CDO/Public Relations) of MASG. He acknowledged that the factory's location is suitable in terms of spatial planning and meets environmental regulations. "We have also implemented zero waste and a sophisticated wastewater treatment plant (IPAL). "In addition to contributing to maintaining the river, it also maintains the sustainability of the local economy, fish remain alive, farmers can still irrigate, residents can still wash dishes without the pungent smell of palm oil," he said. According to him, PT MASG continues to operate in line with its commitment to environmental preservation, "not only clean and clear on paper, everything is through calculations, waste is managed, and the surrounding community is involved," he explained. Regarding waste management, MASG, a palm oil industry, is committed to carrying out its operational activities in accordance with applicable regulations, including managing the impact of its activities and maintaining environmental sustainability. "So it continues to contribute to the regional economy. "Zero waste management is one of the concepts that continues to be promoted," he said. "In accordance with the Zero Waste Policy, MASG strives to reuse, recover, and recycle its production waste." "Since the factory was built, the company has succeeded in realizing waste recycling from the CPO production process up to 100 percent," he added. He touched on ecological improvements including changes in water, air, and noise quality, to see the distribution of water quality according to RI Ministerial Regulation Number 82 of 2001, the variables that continue to be improved are TDS, turbidity, color, pH, Sulfate (SO2), Nitrate (NO2), Nitrite (NO2), Chloride (Cl), Hardness (CaCO2), Iron (Fe), Manganese (Mg), Ammonia (NH2-N), and Organic Substances (KMnO2) in the MASG palm oil mill. "So, regarding the water quality of the MASG palm oil mill, 90% have been examined. Sulfate (SO2), and Ammonia (NH2-N) on the quality standards of turbidity, and color. Every month our factory conducts a complete inspection of the standards," he said. Likewise, regarding the quality of liquid waste, the quality of wastewater shows that the variables namely BOD2, COD, TSS, oil and fat, pH, and N-Total (Nitrogen) are still classified as neutral. For the air quality and noise of the MASG palm oil mill, the variables namely SO2, NO2, Oxidants (O2), dust, and noise, as many as 90% have been checked. So the measurement of noise intensity continues to be improved. Based on wastewater inspection data that has met the highest requirements of 90% both in the examination of pH and N-Total parameters. Meanwhile, solid and liquid waste on empty oil palm bunches, fiber, and fruit shells produced from the processing of fresh fruit bunches (FFB) into CPO are routinely checked and report the results of the inspection in stages, he concluded.
