Published: October 2022

ABSTRACT Jelutung kapur (Dyera lowii Hock) and jelutung sanaman (Dyera costulata) are species that grow well at the peat swamp forest in Canal of Taruna, Kalampangan, Palangka Raya City. Aim of this research was to compare the latex yield between jelutung kapur (Dyera lowii Hock) and jelutung sanaman (Dyera costulata) at the peat swamp forest in Kalampangan. The research was done using factorial design with two factors, i.e. peat thickness (4 m and 5 m) and diameter class of the trees. Variables of the research were diameter (dbh) and height of 24 jelutung kapur and 18 jelutung sanaman. Data were collected each month as long as 11 months with considering the weather condition, i.e. precipitation and temperature. Research result show that there is irreversibility between precipitation vs temperature to latex yield. The more of precipitation so the higher of temperature that cause the reduction of latex yield. According BNT test, the highest latex yield is gotten from jelutung kapur with diameter class of >24 cm that grow at the site with the thickness of 4 m, meanwhile the lowest latex yield is gotten from jelutung sanaman with diameter class of < 24 cm that grow at the site with the thickness of 5 m. Average latex yield of jelutung kapur is 363,63 ml/extract/tree/month.

The existence of the wood needs to be considered so that the use of wood for a particular use needs to pay attention to the quality of wood, both for wood for building materials, furniture, panels, crafts and so on. The weakness of wood compared to substitutes such as metal and concrete is its hygroscopic nature. The aim of this study was to determinethe effect of wood parts treatment on axial direction and sticker thickness on natural drying time on changes in the physical properties of gerunggang wood (Cratoxylon arborescens Bl.). While the expected benefits are as information material for the wood processing industry and wood users to be able to dry the wood properly. The research was conducted at the Forest Products Technology Laboratory for 3 months. Cutting is done by dividing the length of the stem into 3 (three) equal parts in the axial position, namely the base (a1), middle (a2) and end (a3), each cut length ± 2 m for the board (example drying test) ) with ± 2 cm thick and ± 15 cm long for example test of moisture content, specific gravity and shrinkage. The results showed that the average value of fresh water content, saturated point moisture content, and air dry water content had a tendency to decrease in value from the base to the end of the stem. The natural dryingtime has an average tendency to dry more quickly from the base to the end of the stem, with drying times ranging from 28-40 days or an average of 33 days. The end of the wood with a thickness of 3,5 cm sticker dries faster (25 days) with a defect 1 broken edge. Parts of wood with a sticker thickness of 3,5 cm dries faster than the thickness of the stickers 2,5 cm and 1,5 cm. The results of measurements of (BJ) density of gerunggang wood averaged 0,55 including the medium group (BJ 0,4-0,6). Specific gravity has a tendency to increase in value from the base to the end of the rod with an uneven pattern including type 3. The tangential and radial direction shrinkage ratio of 1,88 is included in the medium classification, then gerunggang wood can be used for boards and lightweight construction under the roof, crates, furniture, plywood andconcrete molds. It is recommended to conduct further research on the possibility of using gerunggang wood for artificial boards.Keywords: drying, wood parts, physical properties, gerunggang.

Strong winds that occur can damage the Eucalyptus pellita plant thereby reducing wood production at the end of the rotation. Biometric characteristics are very important to predict the criteria for trees that are at risk of damage due to wind. This study aims to determine the biometric characteristics that play a role in the risk of trees being damaged by wind. The study was conducted on Eucalyptus pellita aged 5 years. The biometric characteristics studied consisted of diameter at breast height (DBH), total height (H) and crown length (CL) as well as the ratio of H/DBH (slenderness inde)x and CL/H (percentage of  crown). Binary logistic regression analysis was used to analyized  the probability of tree damage due to wind. The results showed that the regression model with the independent variable H/DBH was a suitable model. The H/DBH ratio or tree slenderness index is a biometric characteristic that contributes 11,4% to explain the risk of wind damage.

Organizations from all sectors are in a constant struggle to survive and face changes in the globalized and complex environment. Where variables related to human resources that improve performance become relevant to adapt. Under this scenario, the purpose of this document is to identify the relationship between organizational learning and performance, through a systematic review of the literature where selection and inclusion criteria were established, as well as a research strategy. Among the primary findings, it stands out that countries belonging to Asia have been more focused on these issues, since most of the articles reviewed come from there and most of them have a quantitative approach. Furthermore, some researches added variables such as knowledge management, innovation, transformational leadership, among others. It was concluded that these are important subjects, which have been studied very little, and that the qualitative and mixed approach were studied to a lower extent. Therefore, an investigation of both variables has the potential to be innovative and interesting for academy, as well as for entrepreneurs and managers who wish to increase performance.
