dc.description.abstractDalam mencapai pengelolaan hutan lestari di Papua Barat, diperlukan data riap yang akurat untuk menentukan dasar kebijakan manajemen hutan. Namun, perangkat penduga riap yang andal dan praktis belum banyak tersedia. Penelitian ini bertujuan untuk menghitung riap diameter berbagai spesies pohon di hutan alam bekas tebangan dan riap diameter di berbagai kondisi topografi (lembah, lereng, dan bukit), menganalisis perbedaaan riap di antara kelompok jenis (merbau, komersial, dan nonkomersial), serta menyusun model penduga riap diameter berdasarkan kelompok jenis. Penelitian dilakukan pada 9 Petak Ukur Permanen (PUP) PT Wijaya Sentosa di Papua Barat. Riap diameter dimodelkan menggunakan metode linear dan GNLS menggunakan software R. Hasil penelitian menunjukkan bahwa merbau memiliki riap diameter rata-rata tertinggi. Secara topografi, lembah menunjukkan riap tertinggi dibandingkan topografi lainnya. Perbedaan signifikan dalam riap diameter tidak ditemukan di antara kelompok spesies. Model terbaik bervariasi menurut kelompok: M2 untuk Merbau, M8 untuk spesies komersial dan seluruh jenis, serta M13 untuk nonkomersial.-
dc.description.abstractTo achieve sustainable forest management in West Papua, accurate increment data is needed to determine the basis for forest management policies. However, reliable and practical increment estimation tools are not widely available. This study aims to calculate the diameter increment of various tree species in logged-over natural forests and the diameter increment in various topographic conditions (valleys, slopes, and hills), analyze the differences in increment among species groups (merbau, commercial, and non-commercial), and develop a diameter increment estimation model based on species groups. The study was conducted on 9 Permanent Sample Plots (PSPs) of PT Wijaya Sentosa in West Papua. The diameter increment was modeled using the linear method and GNLS using R. The results showed that merbau had the highest average diameter increment. Topographically, valleys showed the highest increment compared to other topographies. No significant differences in diameter increment were found among species groups. The best model varied by group: M2 for Merbau, M8 for commercial species and all species, and M13 for non-commercial.-
