ANTONIUS JUMADI SIHOTANG, NIM. 2010241856, Plant Performance and Quality Analysis of Fresh Fruit Bunches of Oil Palm on Acid Sulfate Land with Different Hydrotopographic Classes. Superviced by Nelvia dan M. Amrul. Khoiri.
Indonesian palm oil agribusiness is faced with limited fertile land, pushing plant cultivation to marginal lands. Acid sulfate soil is marginal land that has the potential to be developed because it has a very large area. Generally, acid sulfate land is located in areas affected by sea/river overflows. This overflow causes acid sulfate land to be grouped into types A, B, C and D. Oil palm planted on acid sulfate land is still classified as having low productivity. In addition to being influenced by the pyrite layer, irrigation factors are one of the limiting factors in oil palm cultivation on acid sulfate land.
This study aims to examine plant performance and FFB quality on acid sulfate land with different hydrotopographic classes in Pehubungan District, Rokan Hilir Regency. Observation parameters in this study include: leaf stalk length, number of leaves, average bunch weight, mesocarp thickness, mesocarp water content and oil content per bunch.
The observation results showed that oil palm planted on type D land showed the highest observation parameters with an average frond length of 573 cm, an average number of leaves of 317.3 strands, an average bunch weight of 17.5 kg/bunch, a mesocarp thickness of 4.4 mm, a mesocarp water content of 31.3% and an oil content per bunch of 14.5%.
Key words: acid sulfate land, oil palm, quality of fresh fruit bunches
