Kerusakan dan Pemulihan Pohon Pinus Akibat Penyadan pada Berbagai Ketinggian Tempat di KPH Kediri

Abstract

Tingkat kerusakan pohon pinus akibat penyadapan didasarkan pada parameter jumlah sadapan, lebar sadapan, tinggi sadapan dan kedalaman sadapan. Ketinggian tempat tumbuh pohon pinus dapat mempengaruhi pemulihan pada bidang sadapan pinus karena kondisi cuaca, suhu udara dan intensitas sinar matahari di setiap ketinggian berbeda. Penelitian ini bertujuan mengetahui kondisi pohon pinus akibat penyadapan, mengukur persentase pemulihan bidang sadapan pohon pinus dan menganalisis pengaruh ketinggian tempat terhadap pemulihan bidang sadapan. Hasil penelitian menunjukkan rata-rata kerusakan sadapan di setiap ketinggian tidak memenuhi prosedur penyadapan getah pinus yang sudah diterapkan oleh Perhutani kecuali rata-rata ketinggian sadapan. Ketinggian tempat berpengaruh terhadap pemulihan bidang sadapan. Rata-rata persentase pemulihan bidang sadapan yang paling tertinggi terdapat di ketinggian <400 m di atas permukaan laut (mdpl) dengan nilai sebesar 50.40%/sadapan dan rata-rata persentase pemulihan bidang sadapan yang paling terendah terdapat di ketinggian >1.000 mdpl dengan nilai sebesar 36.05%/sadapan.

The level of damage to pine trees due to tapping is based on parameters such as the number of taps, the width of the taps, the height of the taps, and the depth of the taps. The altitude at which pine trees grow can affect the recovery of the tapped areas because weather conditions, air temperature, and sunlight intensity vary at different altitudes. This study aims to determine the condition of pine trees due to tapping, measure the percentage of recovery of tapped areas on pine trees, and analyze the influence of altitude on the recovery of tapped areas. The results showed that the average damage from tapping at each altitude did not meet the tapping procedures established by Perhutani, except for the average height of the taps. Altitude affects the recovery of tapped areas. The highest average recovery percentage of tapped areas was found at an altitude of <400 meters above sea level (masl) with a value of 50.40% per tap, while the lowest average recovery percentage of tapped areas was found at an altitude of >1,000 masl with a value of 36.05% per tap.
