STAA manages 15 oil palm plantations spread across four provinces - North Sumatera, South Sumatera, West Kalimantan, and Central Kalimantan. The company also manages plasma plantations in cooperation with smallholders. In line with the group’s mission, STA Resources always enacts the best agronomy practices to increase productivity and efficiency from planting to harvesting.
By the end of 2022, the group’s average annual output of fresh fruit bunches was 23.0 MT per hectare. This yield will expect to continually increase over the upcoming years with continuous operational upgrades and young palm trees entering the productive maturity stage.
Plantations
Waste Management
Palm oil mills produce large amounts of waste, such as Empty Fruit Bunch (EFB) and Palm Oil Mill Effluent (POME), which are recycled back into the fields as organic fertilizers. These effluents are rich in micronutrients and macronutrients that enrich the soil.
Integrated Pest Management (IPM)
IPM is about managing plant-destructing organisms with an ecological approach. Turnera subulata, Antigonon leptopus, and Cassia cobanensis are beneficial plants that can attract predators of nettle caterpillars and bagworms. Tyto Alba (Barn Owl) hunts on rats. Bacillus thuringiensis is a bacteria commonly used to treat bunch moths of Tirathaba species pests.
Mechanization
STAA uses mechanization systems in our operations to promote effectiveness and efficiency. We perform this system on Fresh Fruit Bunch (FFB) collection, fertilizer application, and construction and desilting process of drains.
