Abstract
Land changes become oil palm plantations accused of contributing greenhouse gas emissions (GHG) included in the mineral soil, therefore it is very important to gather information in mineral soil CO2 emissions to support mitigation and adaption to climate change. This purpose of this research determine the CO2 emissions in the oil palm plantations planted crops in the vegetative stage and generative phase, as well as to determine the ratio of CO2 emissions in the oil palm plantations planted crops in the vegetative stage and generative phase. This research was conducted in November 2015 to February 2016 in Subdistrict of Tambang, District of Kampar, Province Riau. The method used in this research was Random Block Design with four treatments and replications. The treatments were oil palm-bera, oil palm-corn, oil palm-soy bean, oil palm-intercropping corn soy bean. The research showed that CO2 emissions in the oil palm plantation intercropped with crops (corn and soybeans) in the vegetative phase showed no significantly different. Comparison large of CO2 emissions indicated oil palm-corn vegetative phase.

Summary
Penelitian dilaksanakan pada bulan November 2015 hingga Februari 2016 di kebun kelapa sawit masyarakat yang terletak di Kelurahan Kualu, Kecamatan Tambang, Kabupaten Kampar terletak pada titik koordinat 101o 17’ 22” BT dan 0o 26’ 56” LU. Peralatan utama yang digunakan dalam penelitian ini yaitu: Infra Red Gas Analyzer (IRGA) tipe LI-820, sungkup gas dari pipa PVC berdiameter 25.5 cm dan tinggi 25 cm. Pengukuran IRGA dilengkapi alat penunjang seperti baterai 12 V, pompa udara 12 V, filter udara, manometer, data logger atau laptop, selang, meteran, kipas, thermometer, parang, dan tali rapia. Metode yang digunakan pada adalah Rancangan Acak Kelompok (RAK) yang terdiri dari empat perlakuan dan empat kelompok sehingga didapat 16 ulangan, emisi gas CO2 tanpa tanaman (bera), emisi gas CO2 pada tanaman jagung, emisi gas CO2 pada tanaman kedelai, emisi gas CO2 pada tanaman jagung dan kedelai di sela kelapa sawit. Pengukuran emisi gas rumah CO2 dilaksanakan pada minggu kelima (fase vegetatif) dan minggu kedelapan (fase generatif) atau dua minggu sebelum panen monokultur jagung, monokultur kedelai dan tumpangsari jagung kedelai
