Abstract

A researched 10 clones of Eucalypts were done in Toba Pulp Forest in 2 sectors of Aek Nauli and Tele as the representative plots. The main objective of the study was to determine the relationship between the number of trees and the average diameter, average branch-free height and average volume of 10 IND clones currently cultivated. in the plantation forest area of PT Toba Pulp Lestari Tbk and compared the volume of wood from 10 IND clones and determined the 3 candidate species recommended for cultivation in the next period. Research method of inventory of stand by circle radius plot of 11.28 m (0.04 ha) with 3 replications summarized plot broaded about 1.2 ha. Based on the wood analysis volume analysis can be resumed that 3 IND eucalypts clones are recommended for planting the next period, namely IND 61, IND 60 and IND 11.

RETRACTED: Pengaruh jumlah pohon, produktivitas dan upah pekerja penyadapan getah pinus terhadap penerimaan negara di Kabupaten SimalungunSihombing, B. H., & Purba, T. (2023). Pengaruh jumlah pohon, produktivitas dan upah pekerja penyadapan getah pinus terhadap penerimaan negara di Kabupaten Simalungun. Jppi (Jurnal Penelitian Pendidikan Indonesia), 9(4), 205-214.Based on the author's request to change the affiliation from Universitas Lancang Kuning to Universitas Simalungun, made on September 6, 2024, this is not permissible as the journal has already been published for one year, and the author is only now requesting the change.The norm is to list the institution where the work was conducted and to indicate the new corresponding address or email in a footnote (or if there is already a footnote, the new affiliation/contact should immediately follow). It appears that minimal work (if any) was conducted at the new institution, so the affiliation should reflect where the work was originally done. Politically, the new institution may want to claim the new publication, and the author might want to assist with this. However, since the work was completed at the prior institution on their salary, the resulting article should maintain that affiliation, with a note providing the author’s new address.
