Description
ABSTRAK. Proses tertahannya curah hujan di atas tajuk vegetasi dikenal dengan istilah intersepsi. Penelitian ini bertujuan untuk melakukan pengukuran intersepsi, air lolos (throughfall), dan aliran batang (stemflow) pada tegakan pohon pinus (Casuarina cunninghamia) pada kelas umur 7, 15 dan 30 tahun. Penelitian ini dilaksanakan di kawasan Taman Hutan Raya, Seulawah, Kabupaten Aceh Besar. Bahan dan alat yang digunakan pada penelitian ini adalah alat penakar curah, gelas ukur, pita ukur, klinometer, dan perangkat lunak Microsoft Excel. Berdasarkan hasil penelitian diperoleh bahwa umur pohon berpengaruh secara signifikan terhadap besarnya jumlah air lolos (throughfall) dan aliran batang (stemflow). Diameter pohon berpengaruh secara signifikan untuk besarnya jumlah air lolos (throughfall) dan aliran batang (stemflow). Umur pohon sangat mempengaruhi tingkat kepadatan tajuk dimana semakin lebat tajuk pohon maka intersepsi semakin besar. Bentuk daun pinus yang berbentuk jarum yang tumbuh dengan rapat juga mempengaruhi intersepsi.Rainfall Interception On The Stands of Pine Tree (Casuarina cunninghamia)ABSTRACT. The process of rainfall retention above the canopy of vegetation is known as interception. This study aimed to measure interception, throughfall, and stemflow on pine trees (Casuarina cunninghamia) at different ages 7, 15 and 30 years old, respectively. This research was conducted in the area of Taman Hutan Raya, Seulawah, Aceh Besar. Materials and tools used in this study were an automatic raingauge, measuring cups, measuring tape, clinometer, and Microsoft Excel software. Based on the research, the results showed that the age of the tree had significantly influenced the throughfall and stemflow. The tree’s diameter had significant influence on the large amount of throughfall and stemflow. The tree’s age greatly affected the density of tree canopy. The more dense the tree canopy, then the greater interception the tree had. The pine needle-shaped leaves densely grew that influenced the interception.
