Abstract

The utilization of the pulai darat tree (Alstonia angustiloba Miq.) is not only for wood but also for sap. The potency ofpulai darat in KHDTK Kemampos is relatively abundant and its sap has not been utilized optimally. This paper observes thetapping techniques and an additional stimulants for enhancing sap production. This study aimed to explore the optimum tappingtechniques and the use of stimulants to improve pulai darat sap production. The combination of two tapping techniques and threestimulants were observed in this study. Result shows that the V-shape tapping produced more sap than half spiral-shape tappingtype and organic stimulants could improve sap production compared to those without stimulants. In this study, wood vinegarstimulants produced the highest sap followed by lime with an average production of 16.75 g and 12.40 g, respectively. Therefore,further tapping innovation is necessary to develop an efficient and effective stem wounding process and stimulants application.

Abstract

Pine resin is one kind of non wood forest products (NWFP) that has passably potency and Indonesia occupies thirdrank in the world as a producer pine resin after China and Brazil. The good market opportunity of gondorukem pushedmanagement of forest to increase pine resin production. This paper aims to give information about harvesting of pine resinusing three tapping techniques. The tapping techniques depends on tapping tool is used, namely mujitech, drill and kedukul.The results showed that the highest production of resin was obtained from the technique using kedukul, 18.0g/quare/collection whereas from Mujitech dan drill was 11.5 g/quare/collection and 11.2 g/quare/collectionrespectively. From visual observation, resin obtained by drill technique was cleaner than Mujitech and kedukul techniques.The content of impurities in pine resin that produced by drill technique was 4% on average. Nevertheless, drill tappingtechnique is not preferred by farmers to apply as less effective.The application of tapping techniques at a certain location were influenced by the customs of the local communities.And those customs were not easy to be changed with new technique although that can produce the tapping more thanmanually technique.

Abstract

The increased demand of pine resin both for domestic and overseas markets has necessitated efforts to enhance pine-sapproduction. The use of strong acid-based conventional stimulants has been long employed by Perum Perhutani, butquestions arise regarding the environment effect as well as growth survival of the tapped pine trees. Consequently, the use ofbiostimulant deserves thorough consideration, since not only will assure friendly-environmental effects but also securing thesustainability of the pine trees. An experiment was conducted to look into the effect of using biostimulants on theproduction of sap (exudates) from the tapped pine trees. Three tapping techniques were employed, i.e. mujitech, boring andkedukul. The biostimulant consisted of three kinds (lengkuas, kencur, and red onion), each with three concentration levels(50%, 75%, and 100%).It turned out different tapping techniques seemed not affecting the pine-sap production, nor did the effect of biostimulantconcentrations (50-100%). However, different kinds of biostimulants did so, whereby lengkuas afforded the sap-yieldincrease the highest (268%) compared to the control (without biostimulants), followed in order by kencur (206%) and redonion (180%). Use of the second and third caused no significant difference. Economically, the use ofbiostimulant at 50% concetration was effective enough. Further attempts are neseccary to find other alternativebiostimulants.

Abstract

The use of trucks in log hauling has many advantages, however tire slip can pose serious problem. Tire slip is not onlyloss in term of log production efficiency, but also damaging the soil road surfaces. Tire chain is one of alternative method toavoid tire slip. This paper studies to find out the slip and the effect of the use of tire chain into the soil damage. The resultsshowed that the use of tire chain was able to reduce the average of tire slip by 95.98%. The average tire slip in normal tirewas 24.85% in the 82.82% moisture content, while the slip in chain added tire was 12.68% in the 84.63% moisturecontent. The use of tire chain can reduce slip and the depth of tire tracks significantly

Abstract

Currently, timber production and biodiversity of natural forest are decreasing. The Ministry of Forestry has put an effort to improve timber production by applying silviculture system namely as Indonesian Intensive Selective Cutting (TPTII) which includes felling technique, land preparation and tree planting. This paper studies productivity, efficiency and felling cost based on TPTII system applied in one of logging company at East Kalimantan by comparing conventional technique and reduced impact felling technique. Results revealed that felling productivity of the conventional technique ranged from 33.74 – 39.87 m3/hour with an average of 36.24 m3/hour which were higher than those of reduced impact felling technique with variation of 28.30 – 36.23 m3/hour and average of 32.8 m3/hour. Felling efficiency of the conventional technique ranged from 84.03 – 88.2% with an average of 86.56%, which were lower than those of the reduced impact felling with variation of 88.75–90.12%, average of 89.36%. Felling cost of the conventional felling technique ranged from Rp1,712 – Rp2,023/m3 with an average of Rp1,8936/m3, lower than those of reduced impact felling technique which varied from Rp1,884 – Rp2,412/m3, and average of Rp2,104/m3. The reduced impact felling technique caused lower felling productivity, however it also improved felling cost and increased felling efficiency. The reduced impact felling could increase benefit as much as Rp321.57 million in a year.

Abstract

Timber hauling has a main goal to remove timber from forestland to the wood processing industry or directly to consumers. The hauling should be managed efficiently, so that the smooth running of transport should be prioritized. Slip is a serious obstacle that must be anticipated when hauling using trucks. It can reduce labor productivity and increase cost of hauling. The experiment was conducted in April 2014 in the RPH Cijogon, BKPH Tanggeung, Cianjur KPH Perhutani Unit III West Java and Banten. The purpose of research is to find out the use of auxiliary tools for reducing road slip in teak land hauling. The auxiliary tools were designed and manufactured in the workshop. The tools were then applied on the truck wheels in various slopes of slip. Results showed that: the average slip on slope class 0-8%, 9-15% and 16-25 % respectively 3.24 %, 6.11% and 7.58 % with each traction coefficient of 0.59, 0.44 and 0.36. The productivity of teak logs using the tools on slope class 0-8 %, 9-15% and 16-25% respectively 92.02 m³/km/hour, 89.07 m³/km/hour and 83.59 m³/km/hour and production, costs of corresponding teak logs are Rp 2640.01/m³/km, Rp 2737.92/m³/km and Rp 2917.27/m³/km.

Abstract

For the formulation of policy strategies on the use of environmentally friendly stimulant in the production of pine resin, the study of innovation stimulant is a necessity. This study aimed to identify the use of stimulants made from a strong acid (inorganic), ETRAT and wood vinegar on pine tapping. Research results revealed that the use of stimulants could increase resin flux and extend. Inorganic stimulant produced resin more than ETRAT and wood vinegar per collection in area with elevation above 500 ASL and below 500 ASL. The use of inorganic stimulant, however, caused the change of wood colour that will be dark brown to reddish even that going into as far as to the pith of wood. Meanwhile, the use of organic stimulant doesn't cause the change of colour in wood significantly. Therefore the use of stimulants on tapping pine needs to consider the negative effects of trees's health, workers and the environment.The economic aspect that should be persued to achieve the financial target, is not the main factor only but the ecological and sosial aspects to achieve a yield sustainability and tree producing are requared.
