| dc.description.abstract | Pendugaan tinggi pohon sering terkendala bias alat konvensional. Penelitian ini mengevaluasi akurasi, presisi, dan efisiensi waktu klinometer dan tongkat ukur terhadap Nikon Forestry Pro pada tegakan Pinus (Pinus merkusii) dan Mahoni Uganda (Khaya anthotheca) di Tahura Djuanda. Hasil pada 80 pohon contoh menunjukkan klinometer jauh lebih andal dan konsisten dibandingkan tongkat ukur. Model koreksi klinometer terbukti paling optimal, bahkan tidak memerlukan koreksi pada tegakan Mahoni Uganda karena akurasi bawaan yang tinggi. Sebaliknya, tongkat ukur memiliki keandalan model yang lemah. Berdasarkan aspek waktu, Nikon Forestry Pro menjadi yang tercepat (14,26–15,45 detik/pohon), diikuti tongkat ukur (33,85–34,94 detik/pohon), dan klinometer (39,05–41,81 detik/pohon). Klinometer direkomendasikan sebagai alat konvensional paling optimal karena keakuratan datanya. | |
| dc.description.abstract | Tree height estimation is often hindered by conventional tool bias. This study evaluated the accuracy, precision, and time efficiency of the clinometer and walking stick against Nikon Forestry Pro in Pine (Pinus merkusii) and Uganda Mahogany (Khaya anthotheca) stands at Tahura Djuanda. Results from 80 sample trees showed the clinometer is significantly more reliable and consistent than the walking stick. The clinometer's correction model is most optimal, requiring no correction in Uganda Mahogany stands due to high inherent accuracy. Conversely, the walking stick has weak model reliability. Nikon Forestry Pro is the fastest (14.26–15.45 s/tree), followed by the walking stick (33.85–34.94 s/tree), and clinometer (39.05–41.81 s/tree). The clinometer is recommended as the most optimal conventional tool due to its data accuracy. | |
