There are around 9 -12 types of essential oil that is being developed and one of them is cananga oil, which is available through distillation process of the flowers. The research aims to investigate the ability of cananga to be propagated trough shoot cuttings method, to discover the effects of growing media and plant growth regulators toward the shoot cuttings’ growth and to determine the suitable growth media and plant growth regulators for the cuttings’ development. The collected data were survival rate in percentage, root growth in percentage, height growth, numbers of developed leaf, numbers of developed primary and secondary roots, and also the length of primary roots. The addition of plant growth regulators gave a significant effect toward survival rate (in percentage), height growth and the numbers of developed leaf of the species whereas the addition of growing media and the interaction between the treatments did not give significant effect on the observed traits. All type of media options could be used for cananga shoot cuttings method and the best growth regulator identified in live percentage parameters, high growth and number of leaves on cananga shoot cutting is Rotoone-F. However, in case of rooting, the best growth regulator is found in addition of Rapid root.</em></p> <p><em>Keywords: Cuttings, Cananga, Media, Plant Gowth Regulator</em></p> Irdika Mansur Taufan Nugraha Copyright (c) 2022 Irdika Mansur, Taufan Nugraha 2022-08-24 2022-08-24 13 02 95 102 10.29244/j-siltrop.13.02.95-102 Kesesuaian Lahan Jenis Tanaman Kehutanan Pada Areal Lahan Terbuka Di Kawasan Hutan Pendidikan Gunung Walat (Hpgw), Sukabumi Jawa Barat <p><em>Gunung Walat Education Forest is a Special Purpose Forest for Education.

Land suitability by looking at topography, soil and climate factors needs to be done to find out the type of forestry plant that is suitable for planting on the open areas. Stages of land suitability, is consisted of image processing, visual interpretation of satellite imagery, ground checks, soil and litter observations, data collection on soil physical and chemical properties and climate, land characteristic observations, and matching processes. The results of matching with Liebeg's minimum law and scoring system showed that eucalypt (E. grandis), sengon (F. moluccana), caliandra (C. calothyrsus), mahagoni (S. mahagoni), pine (P. merkusii), lamtoro (F. moluccana), cajuput (M. leucadendron), damar (A. loranthifolia), acacia (A. auriculiformis), and rasamala (A. excelsa) are suitable for planting in open areas in the Gunung Walat Education Forest (GWEF).

The results of this study indicate that sengon in the 6 months after planting is not affected by pathway treatment, but line planting treatment has a significant effect on upland rice productivity results.

This study aims to examine the efforts and role of the community in controlling forest fires at KPH Cepu, Central Java. The highest incidence of forest fires occurred in 2015 with a frequency of 40 times with a total area of land that burned 140.0 Ha. Forest fires in 2015 were the largest forest fires in the Cepu KPH, costing Rp38.292.909. The form of control carried out by the KPH Cepu itself is through counseling or socialization related to fire and how to deal with it in the event of a fire. The form of direct counseling is given to the LMDH community association, RT association, and other unspecified associations.
