Abstract. Ruminant-oil palm plantation integration is one of agricultural practices, which commonly applied in Indonesia since the introduction of a "Sistem Integrasi Sapi - Kelapa Sawit" (SISKA) or "System Integration Cattle --Oil Palm Plantations" in 2011. In this production system, grasses species in oil palm plantation are potential forage source for development of cattle production in Indonesia. There are around 12 million ha of oil palm plantations in Indonesia divided into three parts: (1) private plantation enterprise (52%), (2) small-holder's plantation enterprise (41.42%) and (3) state-own plantation enterprise (6.72%) owned by foreign companies.
Oil palm plantation has been spread out in 25 provinces of Indonesia, but mostly in Sumatera and Kalimantan with a total CPO production of 33.5 million tons. In addition to producing CPO as the mainstay, the oil palm plantation produces several forage grasses and legumes for cattle grazing as well as oil palm industry produces types of by-products potential to be used as animal feed, namely palm press fiber (PPF), mud palm sludge (PS), oil palm frond (OPF) and palm oil trunk (POS) obtained from palm oil plantations.
