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

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

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.

Abstract

Most of the local honey production in East Kalimantan is managed traditionally, thus honeyquality, particularly its physical and chemical properties, are unknown. However, the honey analysisSURYLGHVDFRPSUHKHQVLYHFRPSRVLWLRQSUR¿OHDQGSRWHQWLDOO\JLYHVKLQWVWRLPSURYHWKHTXDOLW\RIlocal honey from East Kalimantan. This research aimed to analyse the properties of two local honeyfrom East Kalimantan. The methods used in this study were gravimetric, volumetric, spectroscopy,spectrophotometry, and chromatography. Honey A was produced by Apis cerana whereas Apis dorsataproduced honey B. The color intensities were 560±5.66 and 947.5±27.58 mAu for honey A and B,respectively. Honey A and B a had moisture content of 22.7 and 25.8% w/w, respectively. Otherproximate analysis parameters were also reported. Fructose and glucose content for honey A were30.65±2.35% w/w and 30.08±0.58% w/w, while honey B gave different pattern with fructose at28.06±1.04 and higher glucose instead at 32.74±1.13% w/w. Reducing sugar and total sugar forboth samples were higher than 60% w/w while sucrose in honey A and B were 2.8 and 1.4% w/wrespectively, thus indicating no adulteration.
