Abstract
Palm oil is one of the plantation commodities that has an important role in the economy in Indonesia. Indonesia is one of the largest palm oil producing countries in the world. In Indonesia, almost 75% of the provinces have oil palm plantations. The 5 provinces with the most production are Riau, Central Kalimantan, North Sumatra, West Kalimantan, and East Kalimantan. Production results in 2020 reached 1931.88 thousand tons with a maximum production of 9984.3 thousand tons. The distribution of oil palm production can be modeled spatially using several anisotropic semivariogram models, namely exponential, spherical, and Gaussian. The best model is obtained by selecting the sum of the least squares of errors. Through the best model, it is found that the greatest intensity is the island of Borneo. The potential for production development can be increased for the provinces located on the islands of Sumatra and Sulawesi.
