Abstract

This research aims to determine the influence of organic stimulants and stimulant concentrations on pine resin production, to obtain alternative stimulants that are safe for the environment and can also increase pine resin production. The research design used a Completely Randomized Design (CRD), with a factorial experiment consisting of two factors, namely the organic stimulant type factor which consisted of 3 levels, namely the stimulant extract of shallots, ginger and galangal and the stimulant concentration, which consisted of 3 levels, namely 100% concentration. , 75% and 50% plus control, so there are 9 treatment combinations. Replication was carried out 6 times so that 54 tree samples were obtained plus 6 control trees, or a total of 60 tree samples. The results of the research showed that the average production of pine resin in the stimulant treatment types of onion, ginger, galangal and control extracts was 76, 28 grams, 76.28 grams, 140.06 grams and 21.23 grams, respectively. The results of the variance analysis show that the type of stimulant shows a very real influence, while the concentration of the organic stimulant shows an insignificant influence. Further test results showed that the organic stimulant galangal extract had a significant difference from the organic stimulants of ginger and shallots, while the organic stimulants of shallots and ginger showed no significant differences. The research results also showed that the sap production of the onion and ginger extract stimulant treatment showed sap production that was not significantly different from the control, however, the galangal extract stimulant treatment showed a significant difference.

Abstract

Pine resin is a non-timber forest product, which has the potential to be developed in Indonesia. One of the pine resin products is gondorukem which has a very wide market. The purpose of this study was to determine the best tapping method, in order to obtain optimal production of pine resin tapping in three age classes of pine trees, namely age classes III, IV and V. The results showed that the average yield of pine resin tapping with the quare method was 18 ,88 gr and drill method 17,77 gr. Meanwhile, the highest average production of sap in age class III was 26.11 g and the lowest was in age class V of 10.21 g. The results also showed that along with the increase in the age class of the plant, the production of tapping sap also decreased significantly, both for tapping pine sap using the drill method, and tapping pine sap using the quare method. The results also showed that as the age class of the plant increased, the use of the quare method gave a higher average yield of 18.88 gr than the drill method of 17.77 gr. Keywords : Age class; tapping method; pine resin production

Abstract

The development of modern industries has demanded ever-increasing usage requirements for wood products. The use of wood will be more effective and efficient if the properties of wood are known beforehand. This study aims to determine the anatomical diversity of sengon wood and its possible use as a raw material for furniture. This study used a randomized block design with Tukey's follow-up test. The factor used consisted of the radial direction of wood (wood near the skin and wood near the heart). Parameters observed were the proportion of fiber cells (%), the proportion of vessel cells (%), the proportion of parenchyma cells (%), and the proportion of radius cells (%). The results showed that the wood near the skin and near the heart of sengon had variations in the proportion of fiber cells, the proportion of vessel cells, the proportion of parenchyma cells and the proportion of radius cells. The average value of the anatomical diversity of sengon wood in the radial direction is the proportion of fiber cells 49.02 - 50.24 %, the proportion of vessel cells 23.22 - 24.23 %, the proportion of parenchyma cells 13.47 - 14.57 %, the proportion of finger cells finger 11.53 - 13.39 % and . Sengon wood can be used as furniture material for light buildings or for artificial boards because it has a high proportion of fibers.

Abstract

Aek Natonang Arboretum Ecotourism in Samosir Regency, North Sumatra Province has natural beauty that can be used as a tourist attraction for every visitor. The natural beauty that is owned in reality is not calculated into economic value or market value, so it is important to do economic valuation. By doing this research, it can be known the characteristics of visitors, the amount of economic value of Aek Natonang Arboretum ecotourism based on the travel cost method and find out the factors that influence the intensity of visits. The economic valuation method used is the travel cost method. The travel cost method is applied to estimate the economic value of Aek Natonang Arboretum ecotourism by calculating the cost of travel expenses. Data on travel costs and the number of visits were collected through interviews using questionnaires to visitors within a certain period of time. Then proceed with multiple linear regression analysis to determine the factors that affect the intensity of ecotourism visits to Aek Natonang Arboretum. The results of economic valuation with the travel cost method obtained an average value of Rp238.170,00/visit and the economic value of Aek Natonang Arboretum ecotourism is Rp2.358.359.340,00/year. Factors that influence the intensity of visits are distance, length of travel and travel costs.
