Abstract

Currently, timber trade requires that wood products must come from legally and responsibly managed forests. In Indonesia, to prove that wood products are legal if they are equipped with Legitimate Certificate of Forest Product, V-legal mark and electronic label in the form of Barcode. One method of proving wood origin in timber harvesting is log tracking method through labeling. This study examines the accuracy of log tracking in a Timber Forest Product Enterprise of Natural Forest (IUPHHK-HA) PT. Sumalindo Lestari Jaya II in Mahakam Ulu District, East Kalimantan Province. The log tracking was accomplished by tracking the comformity between wood documents in production result report (LHP), the numbered tree label attached on the stump till the cruising result report (LHC) document. Methods of sampling of LHP wood documents were conducted purposively through sample plots in three different felling sites. Results showed that timber traceability based on the LHP document to the tree number label attached on the tree stump wae 100%. However the level of log traceability from LHP documents to LHC documents ranges from 85.7–100% with average of 96.2%. Mismatch information between timber documents on LHP, the stump and LHC was mainly caused by wrong group of wood species and tree diameter classes.

Abstract

The surface color of bamboo stem changes naturally due to surrounding conditions. This paper studies the changesin bamboo surfaces color due to room temperature drying (KU) and oven drying (KO) at 60±2 °C. The color changesof four bamboo species: mayan (Gigantochloa robusta Kurz.), ater (Gigantochloa atter (Hassk) Kurz. Ex.Munro), ampel kuning (Bambusa vulgaris var. striata), and wulung (Gigantochloa atroviolacea Widjaja) werestudied together with their correlation to water loss. Color measurements were conducted based on CIE-Lab system,while water content related to weight loss and thickness shrinkage during KU and KO. The result showed that therewas a close relationship between water loss and discolouration of bamboo culms. The water loss of mayan, ater, andwulung showed a positive linear correlation to change of bamboo surfaces color, where the higher water loss affect greatervalue of color change too. Oppositely, in ampel kuning, higher water loss, affect smaller color change value (negativelycorrelated). This was because the natural color of ampel kuning in fresh conditions is not much different from colorafter drying. KU treatments, biggest thickness shrinkage was mayan = 46.03%; biggest weight reduction was ampelkuning = 28.52%; and biggest color changes (ΔE*) was ater = 15.51%. KO treatments, biggest thickness shrinkagewas mayan = 52.4%; biggest weight reduction was yellow ampel = 31.19%; and biggest color changes (ΔE*) wasater = 18.8%.

Abstract

Timber utilization is mostly affected by wood chemical composition and its natural durability in certain condition. This paper studies chemical composition and under shade natural durability of eight wood species originated from Banten and West Java Provinces. Chemical composition was tested based on Norman and Jenkins’ methods, SNI 140492-1989 and SNI 14-1032-1989 and the wood natural durability test was conducted outdoor under the shade. Result shows that in general wood chemical composition of eight wood species tested is approximately in average of those in broad leaf trees. Among the wood samples studied, the highest holocellulose content was recorded from baros wood (Michelia champaca L.) which was about 75.64% and the lowest holocellulose content was recorded from pasang taritih wood (Lithocarpus elegans Blume Hatus ex Supadmo) which was about 60.19%. In term of lignin content, the highest percentage was recorded from pasang taritih wood, which was about 35.14% and it is comparable with those of ki hiyang (Albizia procera (Roxb.) Benth.) wood, which was about 25.35%. The greatest extractive content was recorded from tarisi wood (Albizia lebbeck (L) Benth), which was about 7.9%, while extractive content nemely tangkalang wood (Litsea roxburghii Hassk) falled into 1.54%. Under the shade durability test showed pasang taritih wood performed second class durability (class II), while the other seven wood species of tarisi, ki hiyang, hanja, cerei, tangkalang, baros, and kapinango were extremly non durable (class V).

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

Oil palm trunk is lower in dimensional stability, density, physical, and mechanical properties than other wood species. Efforts to overcome the weakness of the oil palm trunk properties could be conducted through densification with hot pressing and chemical adhesive addition. This paper studies optimum composition of Tannin Resorcinol Formaldehyde (TRF) in its application for improving the quality of oil palm trunk. The tannins were water extracted at 75°C and further copolymerized with resorcinol and formaldehyde. TRF was studied through functional group analysis using infrared spectroscopy and cristallinity test using X-ray diffraction. The TRF adhesive was applied through compregnation process. Results showed that reactivity of tannins in bark of Acacia mangium was 65.82%, the optimum adhesive composition of TRF (v/v) was = 1:0.05:0.05 with solid content of 8.33%, 0.09% free formaldehyde, and the degree of crystallinity was 10.92%. Tannin extract has a specific character on the wave number corresponding to the characteristics possessed by the imported tannin acacia standard. The presence of new functional groups and an increase in absorbance intensity of uptake at several wave numbers through infrared spectroscopy analysis on TRF as well as compregnated oil palm trunk indicate the occurrence bonds attributted by ether and methylene bridges to TRF and chemical compound on oil palm trunk. Oil palm trunk after compregnation significantly increased its density by 104.61%, hardness became 6 fold, and decreased the thickness swell to 85.98%. The oil palm trunk after compregnation also increased in quality from a wood strength class V to a wood strength class III, then, its potential for manufacturing exterior products.

Abstract

Various sawmilling industries of high, medium and small enterprises operate in Indonesia. During log conversion into sawn timber, wood waste occurs in the form of left over cut and sawdust. Small cut waste is lignocellulose material which is potentially used for bioethanol production. This paper studies the possibility of bioethanol production from sengon sawmill waste. High loading substrate method was applied by hydrolyzing high concentration substrate, i.e 15, 25 and 35% and two concentrations of enzymes (12.5 and 15 FPU/g substrate). Result showed that the treatment of 25% substrate concentration and 15 FPU/g cellulase substrate produced the highest reducing sugar of 248.3 mg/mL, while the substrate concentration of 35% generated the highest ethanol content i.e 17.7% and recovery about 38.4%. It can be concluded that the high loading substrate method could increase the ethanol concentration made from sengon wood waste.

Abstract

The quality of the cement board depends on the compatibility between cement and particles fromlignocellulosic biomass. The purpose of this study was to determine the compatibility between cementand particles from four tropical wood namely mangium (Acacia mangium Willd), teak (Tectona grandisLinn. F.), gelam (Melaleuca leucadendron (L.), dadap (Erythrina variegata L.), and sago stem (Metroxylonsago Rottb.), and to determine the physical and mechanical properties of the mangium cement boardproduced by adding magnesium chloride (MgCl2) as an accelerator. This research was conducted intwo steps. The first step consisted of measuring the hydration temperature of a mixture of cement with particles from the four wood species and sago stems by adding magnesium chloride (MgCl2),with variations of 0%, 2.5%, 5%, and 7.5% based on the cement weight. Two types of mixturesfrom the first step were then used in the second step, namely the manufacture of cement board. The cement board was made using a weight ratio of mangium particles:cement:water of 1:2.7:1.35. Theboard is made with a target density of 1.2 g/cm3. Physical and mechanical testing refers to the ISO8335-1987 standard. The results of the hydration temperature showed that all of the mixtures wereclassified into “low inhibition”, except for mixture between cement and mangium particles without a catalyst which was included in the classification of “moderate inhibition”. While the results of cement board tests indicate that the cement boards made from mangium wood particles with 5%MgCl2addition had better properties compared to mangium cement boards without catalysts.

Abstract

The minimum requirement of bioethanol utilization (E100) as a mixture of fuel oil is required as much as 20%,of the total needs in January 2025 as stated in the Regulation of the Minister of Energy and Mineral Resourcesnumber 12 in 2015. Indonesia is a country that has many potential raw materials for the development of bioethanolas renewable energy, such as sea pandanus plants (Pandanus tectorius) and food industry wastes such as thewheat industry. Sea pandanus plants are commonly found throughout the Indonesian archipelago and are availableendemically. While wheat industrial waste is available in industrial areas such as in Banten Province, which has so farnot been utilized as a source of biofuels. The purpose of this research is to get bioethanol product from new sources basedon natural materials and industrial waste. The stages of research began with raw materials preparation, proximateanalysis, gelatinization, liquefaction, pre-saccharification, fermentation, distillation process, and quantitative analysisusing instruments. The results showed that the sea pandanus leaf had the potential for bioethanol synthesis with thehighest amount of recovery and efficiency were 309 mL and 0.62 mL/g respectively, whereas based on the results ofgas chromatography (GC) analysis, the bioethanol product which had the highest purity was from wheat bran waste witha purity level of 97.64%.

Abstract

Currently, Ganoderma lucidum, Pleurotus ostreatus, and P. sajor-caju are prospective fungi for decomposition of pulp and paper industry’s waste. This paper studies the possible utilization of rotting fungi spent compost for decomposition of mangium sludge. Initially, the fungi were cultivated for three months on medium prepared from sengon (Falcataria moluccana) wood sawdust. The rotting fungi spent compost was then used for degrader activator by inoculating them into the Acacia mangium sludge, then, incubated for six months. Results revealed that after three month incubation the values of the Biological Conversion Efficiency (BCE) of sengon reached 13.41% (G. lucidum), 47.11% (P. ostreatus), and 38.06% (P. sajor-caju). Fungal inoculation into the sludge improved the C/N ratio as much as 71.59%. The usage of higher concentration of G. lucidum inoculums increased the C/N ratio value. After six months incubation, some sludge contents reduced by 48.76% (N), 35.42% (P) and 25% (K), except for Ca and Mg, which increased by 112.9% and 6.67%, respectively. Mineral content of the untreated sludge decreased by about 66.12% (Ca), 68.75% (P) and 4.17% (Mg), except for K and Ca which were increased by 2.08% and 64.52%, respectively. Cation exchange capacity (CEC) value of the sludge after incubation increased by about 3.85% (control) and 56.8% (treated).

Abstract

Over the last five years (2013−2017) there has been a deficit of ± 23.2 million m3year of wood raw materials,while the facts in the field of timber harvesting are still wasteful with leaving logging waste reaching an average of 17%of the annual production quota target of 9.1 million m3/year. The trial of zero waste-based and environmentallytimber harvesting method (ZWL) is important to strengthen the tree length logging methods. This research aimed toobtain data and technical information related to the efficiency of wood utilization and the potential of timber loggingwaste. The trial results showed that zero waste and environmentally timber harvesting methods could improve woodutilization efficiency by 9%, from an average of 82.9% to an average of 91.9%, and reduce the potential for clearbole (BBC) logging waste from an average of 12% (0.863 m3/ tree) to only 8.1% (0.418 m3/tree). In addition, itwas able to save the potential of logging waste from stems above the branch (BAC) ranging from 2.8−11.2% with anaverage of 6.4% (0.418 m3/tree). However, ecologically it could not reduce damage to residual stands which reached37.7% while conventional methods amounted to 38.8%. Potential logging waste both BBC and BAC were mostlydefective (50.5−58.3%), and some were still good (14.4−26.3%) while those with broken conditions were still quitehigh (22.6-27.3% ). Until now, the potency of timber harvesting waste has not been utilized due to the considerationof the high cost of Non-Tax Government Income (PNBP) levies, uncertainty in the application of the Minister ofEnvironment and Forestry Regulation Number: P.1/Menlhk/Setjen/Kum.1/1/2019, and the ZWL method hasnot been informed yet to minimize the cost of logging waste extraction. In order to reduce timber harvesting waste andresidual stand damage, the forest management refresh logging and skidding techniques to improve the skills of thechainsaw and the tractor operators.
