ABSTRACT Oil palm (Elaeis guineensis Jacq.) is one of Indonesia's prime crops. The Riau Province Plantation Office (2013) noted that in 2013 the area of oil palm plantations on peatland had reached around 1.2 million hectares. Of the total peatland area of oil palm plantations in Riau Province, there are different peat depths. The depth of peat determines the level of peatland production, because it greatly affects the fertility of peat soil and the availability of nutrients. Shallow peat has a higher fertility level than medium peat, deep peat and very deep peat. There have not been many studies and data collected on oil palm in peatlands at various depths, and the differences in the performance and production of oil palm plants at various depths of peat have not been studied. The research was conducted using a survey method, and the location was determined using purposive sampling. The sampling points were determined using the Stratified Random Sampling method where the strata were grouped based on the depth of the peat, namely shallow peat, medium peat, deep peat and very deep peat. Sampling was repeated as many as 5 samples. Observations of oil palm plant growth were made by taking data on the size of the plant height, number of leaves and stem circumference as many as 3 replicates. So that the total sampling unit of oil palm plants is 60 units. Parameters carried out are plant height, number of leaves, stem circumference, production yield and average basket weight of oil palm. The data obtained were analyzed using the analysis of variance (ANOVA) method and to determine differences between treatment averages were analyzed using Duncan multiple range test (DNMRT) at the 5% significant level. The results showed that different depths of peat caused differences in the peatlad characteristic, performance and production of oil palm plants. As the depth of the peat increases, bulk density (BD), water level, pH, C-organic, N-Total and P-Total decrease, while the total pore space (TRP) and permeability increase. In shallow and medium peat, there was no significant difference in the performance and production of oil palms, however, from medium peat to deep peat and very deep peat, there was a decrease in the performance and production of oil palms.

ABSTRAK
Kelapa sawit (Elaeis guineensis Jacq.) merupakan salah satu tanaman unggulan Indonesia. Dinas Perkebunan Provinsi Riau (2013) mencatat pada tahun 2013 luas perkebunan kelapa sawit di lahan gambut telah mencapai sekitar 1,2 juta hektar. Dari total luas lahan gambut perkebunan kelapa sawit di Provinsi Riau, terdapat perbedaan kedalaman gambut. Kedalaman gambut menentukan tingkat produksi lahan gambut, karena sangat mempengaruhi kesuburan tanah gambut dan ketersediaan unsur hara. Gambut dangkal memiliki tingkat kesuburan yang lebih tinggi dibandingkan dengan gambut sedang, gambut dalam, dan gambut sangat dalam. Belum banyak penelitian dan pengumpulan data tentang kelapa sawit di lahan gambut pada berbagai kedalaman, dan perbedaan performa dan produksi tanaman kelapa sawit pada berbagai kedalaman gambut belum banyak diteliti. Penelitian dilakukan dengan metode survei, dan penentuan lokasi dilakukan secara purposive sampling. Titik pengambilan sampel ditentukan dengan metode Stratified Random Sampling dimana strata dikelompokkan berdasarkan kedalaman gambut yaitu gambut dangkal, gambut sedang, gambut dalam dan gambut sangat dalam. Pengambilan sampel diulang sebanyak 5 sampel. Pengamatan pertumbuhan tanaman kelapa sawit dilakukan dengan mengambil data ukuran tinggi tanaman, jumlah daun dan lingkar batang sebanyak 3 ulangan. Sehingga total sampling unit tanaman kelapa sawit adalah 60 unit. Parameter yang dilakukan adalah tinggi tanaman, jumlah daun, lingkar batang, hasil produksi dan rata-rata bobot keranjang kelapa sawit. Data yang diperoleh dianalisis dengan menggunakan metode analysis of variance (ANOVA) dan untuk mengetahui perbedaan rata-rata perlakuan dianalisis dengan menggunakan Duncan multiple range test (DNMRT) pada taraf nyata 5%. Hasil penelitian menunjukkan bahwa kedalaman gambut yang berbeda menyebabkan perbedaan karakteristik lahan gambut, penampilan dan produksi tanaman kelapa sawit. Dengan bertambahnya kedalaman gambut, kerapatan curah (BD), tinggi muka air, pH, C-organik, N-Total dan P-Total menurun, sedangkan ruang pori total (TRP) dan permeabilitas meningkat. Pada gambut dangkal dan sedang tidak terdapat perbedaan yang nyata pada kinerja dan produksi kelapa sawit, namun dari gambut sedang ke gambut dalam dan gambut sangat dalam terjadi penurunan kinerja dan produksi kelapa sawit.
