We compared the content and quality of kayu putih oil in leaf-twig samples from Melaleuca leucadendron LINN plantations with different fanning systems in Java, Indonesia. In the monoculture plantation (Site G, Central Java) and single-crop tumpangsari (Site I, West Java), cineole content in oil was higher than in the multiple-crop tumpangsari (Site P, East Java). In the monoculture, cineole content was high in 10- to 26-year-old stands, but decreased in older stands. In the two sites with tumpangsari systems, cineole content did not decrease in older stands. Cultivation and soil tilling may mitigate soil degradation and contribute to sustaining kayu putih oil quality in plantations with tumpangsari systems as stands increase in age. Cineole content in kayu putih oil produced in the three plantations in Java Island, ranged 67 72%, indicating that under appropriate farming systems and site conditions, kayu putih oil is comparable in quality with aromatic oils from other myrtaceous species.
