Perubahan Sifat Fisika Tanah akibat Penumpukan Tandan Kosong Kelapa Sawit di Perkebunan Kelapa Sawit di Kecamatan Juli Kabupaten Bireuen

Abstract

Abstrak. Tandan kosong kelapa sawit merupakan limbah terbesar yang dihasilkan oleh perkebunan kelapa sawit. Sifat fisika tanah merupakan faktor lingkungan yang sangat mempengaruhi ketersediaam air dan udara dalam tanah dan secara tidak langsung mempengaruhi ketersediaan unsur hara bagi tanaman. Memperbaiki sifat fisik tanah antara lain : permeabilitas tanah, porositas tanah dan air tersedia tanah. Penelitian ini menggunakan metode survey deskriptif berupa tahap persiapan, pengambilan sampel di lapangan dengan menggunakan ring sample, pengambilan sampel dilakukan sebanyak 20 sampel tanah. Titik pengambilan sampelnya adalah tanpa pemberian tandan kosong kelapa sawit dan diberikan tandan kosong kelapa sawit. Setiap titik pengamatan dilakukan pengambilan sampel sebanyak lima kali. Titik pengambilan sampel tanah diambil secara zigzag  pada blok yang sudah ditentukan di kebun kelapa sawit. Dilakukan uji statistika dengan menggunakan uji-T satu sampel. Lalu sampel tanah tersebut dianalisis di Laboratorium Fisika Tanah Fakultas Pertanian Universitas Syiah Kuala. Hasil penelitian menggunakan data SPSS dimana masing-masing parameter ada yang menggunakan tanpa diberikan tandan kosong kelapa sawit dan diberikan tandan kosong kelapa sawit. Dari data output SPSS yang diberikan tandan kosong kelapa sawit yang berbeda tidak nyata adalah permeabilitas tanah, porositas tanah, dan air tersedia tanah.

Changes in Soil Physical of the Soil due to the Accumulation of Empty Palm oil Bunches in Palm Oil Plantations in Juli District Bireuen Regency

Abstract. Empty oil palm bunches are the largest waste produced by oil palm plantations. Soil physical properties are environmental factors that greatly influence the availability of water and air in the soil and indirectly influence the availability of nutrients for plants. Improving the physical properties of the soil include: soil permeability, soil porosity and available soil water. This research used a descriptive survey method in the form of a preparation stage, sampling in the field using a ring sample, sampling was carried out on 20 soil samples. The sampling point was without empty oil palm bunches and empty oil palm bunches were given. Each observation point was sampled five times. Soil sampling points were taken in a zigzag manner from a block in the oil palm plantation. Statistical tests were carried out using the one-sample T-test. Then the soil samples were analyzed at the Soil Physics Laboratory Faculty of Agriculture Syiah Kuala University. The results of the research used SPSS data where each parameter was used without being given empty palm oil bunches and given empty palm oil bunches. From the SPSS output data provided by empty palm oil bunches, the differences that are not significant are soil permeability, soil porosity, and available soil water.
