| dc.description.abstract | Informasi potensi biomassa pohon sangat berkaitan dengan kemampuan vegetasi dalam menyerap CO2 yang merupakan salah satu polutan yang dapat menyebabkan terjadinya efek rumah kaca. Eukaliptus merupakan salah satu jenis pohon yang diusahakan di hutan tanaman industri di Indonesia dengan periode rotasi yang relatif singkat (3–5 tahun) dan dapat berperan sebagai penyerap karbon dioksida. Penelitian ini bertujuan memperoleh model alometrik untuk menduga biomassa total pohon eukaliptus hibrida di unit pengelolaan hutan tanaman di Sumatra Utara. Pohon contoh yang digunakan dalam penelitian ini meliputi 75 pohon dengan sebaran diameter 1.46 hingga 17.52 cm. Model alometrik disusun menggunakan CurveExpert Basic 2.2.3 dan RStudio 4.4.0 yang menghasilkan 5 model terpilih, yaitu power (M1), eksponensial (M2), polinomial (M3), rasional (M4), dan Hoerl (M5). Selanjutnya, kelima model tersebut dilakukan validasi yang juga melibatkan dua model alometrik yang sebelumnya sudah ada di tempat yang sama dan menghasilkan model M1 (W = 0.08378*D^2.49572) sebagai model terbaik, yaitu model yang menunjukkan akurasi lebih baik dibandingkan dengan model alometrik lainnya untuk pendugaan biomassa pohon eukaliptus hibrida. | - |
| dc.description.abstract | Information on tree biomass potential is closely related to vegetation’s ability to absorb CO2, which is one of the pollutants that can cause the greenhouse effect. Eucalyptus is one of the tree species that cultivated in industrial forest plantations in Indonesia with a relatively short rotation period (3–5 years) and can act as a carbon dioxide sink. This research aimed to obtain allometric models to estimate the total biomass of eucalyptus hybrid trees in a forest plantation management unit in North Sumatra. The sample trees used in this research included 75 trees with a diameter distribution of 1.46 to 17.52 cm. The allometric models were developed using CurveExpert Basic 2.2.3 and RStudio 4.4.0 resulting in 5 selected models, namely power (M1), exponential (M2), polynomial (M3), rational (M4), and Hoerl (M5). Furthermore, model validation was carried out on the five models, which also involved two other allometric models that previously developed in the same place, and resulted in model M1 (W = 0.08378*D^2.49572) being the best model, which showed better accuracy compared to other allometric models for estimating the biomass of eucalyptus hybrid trees. | - |
