Abstract

The kapok seed oil is non-edible oil so it is very profitable as a raw material for making biodiesel. However, the kapok seedoil is dominated by long chain and unsaturated fatty acids. These types of fatty acids tend to reduce the quality of biodiesel, namelythe low cetane number and trigger polymerization reactions during combustion. Ozonation could be applied to shorten the carbonchain and the number of double bonds in fatty acids from kapok seed oil. This research aims to study the effect of time of ozonationat preparation stage of kapok seed oil on biodiesel characteristics of esterification stage with the assistance of ultrasonic waves. Theozonation time was varied for 60, 90, and 120 minutes. The results showed that the longer the time of ozonation the kapok seedoil produced with the increased acid number. The greater acid number of the kapok seed oil was verified by the fatty acid compositionof Gas Chromatography-Mass Spectroscopy analysis, showed that the fatty acid structure of the kapok seed oil became simpler.The esterification for 120 minutes to ozonated kapok seed oil which has been ozonized produces oil phase with an acid number of10.6 mg KOH/g, a saponification number of 112 mg KOH/g, and a density of 903 kg/m3.

Abstract

Flavonoid compounds obtained from natural products could reduce the risk of cancer. Akway plants (Drimys beccariana, Gibbs) are endemic plants in the Papuan highlands, especially in Manokwari. D. beccariana has been widely used in traditional medicine in West Papua. This study aims to determine the cytotoxic activity of flavonoid from D. beccariana bark against T47D breast cancer cells. Pure compound form isolation was characterized using UV and IR spectrophotometers, and tested cytotoxic activity against T47D breast cancer cell using the Sulforodamine B. method. The D. beccariana stem bark (2.5 kg) was extracted with methanol solvent which was then partitioned with n-hexane and ethyl acetate solvents. Ethyl acetate fraction was separated and purified by column chromatography method to yield pure compound (7.1 mg). The UV-Vis spectrum of pure compound showed two bands at λmax 287 (I) and 205 nm (II), as well as the addition of AlCl3 shifting reagents with the addition of 7 and 5nm wavelengths, specific to the -OH and C=O groups in flavonoid compound. The infrared spectrum of pure compound (KBr) showed the presence of –OH stretch (3422 cm-1), C=O (1659 cm-1), C= C aryl (1463 cm-1), and C-O (1060 cm-1) which is typical for flavonoid. The pure flavonoid compound obtained from the of D. beccariana bark showed cytotoxic activity against T47D breast cancer cells with IC50 values of 3.2 µg/mL. D. beccariana is a promising source of breast anticancer agents.

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

A designer needs to simplify the bamboo cross-section shape variation to the closest standard geometry so a structural analysisof bamboo construction can be carried out. Bamboo culm’s cross-sectional geometrics vary and may be similar to conic such as acircle, ellipse, or egg-shape ring. The best-fit conic section, which is the most similar to the actual geometric shape of the bambooculm’s cross-section, should be considered. This study formulates mathematical equations for calculating the bamboo culm’s crosssectional properties (including the area, the first moment of area, the centroid, and the moment of inertia), which are fitted by acircle, ellipse, and egg-shaped ring. The thickness, diameter, major axis, and minor axis of four bamboo species (i.e., Gigantochloaapus, Bambusa vulgaris, Gigantochloa pseudoarundinacea, and Gigantochloa robusta) were measured, and thosevalues were substituted into the equations to produce the range of cross-sectional properties of each species.

Abstract

Electrical storage and distribution devices become important in next generation to help integrate more renewable energy intothe electricity grid. Supercapacitor technology is considered the most promising alternative to Li-ion batteries, which have limitedLithium material. However, the low energy density is a weakness of supercapacitors, even though they have a high-power density.Activated carbon-based supercapacitor electrodes have ideal potential for development. The inherent attributes of activated carbon,pore properties, and functional groups, are responsible for improving the performance of supercapacitors. The main challenge for theresearchers is the pore size distribution, micro (<2nm), meso (2–50 nm), and macro (>50 nm), which varied in activated carbon.Micro pores have an impact on increasing the value of specific capacitance values which will encourage an increase in energy density.Meso pores have an impact on the overall accessibility of the electrode surface by electrolyte ions. Future studies will emphasize oncarbonization and activated carbon activation techniques to improve the surface quality of activated carbon.

Abstract

The traditional society's need for natural honey cannot easily be met with the many alternatives to commercial honey today,but the consistency of traditional methods in determining the authenticity of natural honey has not been scientifically confirmed. Thissimple research aims to study the relationship between the boiling point and mass percentage of some dilute natural honey based onthe basic idea of the colligative properties of the solution and its comparison with some commercial honey samples. Each honeysample (six samples of natural honey and six samples of commercial honey) was diluted with distilled water in various weightpercentages of 2.5–15.0% (w/w), then the boiling points were determined in ambient temperature and pressure. By using polynomialregression of degree 3, it was found that all-natural honey solutions had a pattern of increasing boiling point with increasing weightpercentage, with different curvature patterns approaching linear (R3Lin), logarithmic (R3Log), exponential (R3Exp), and sigmoid(R3Sig) like patterns. The results of the comparison with six commercial honey solutions, there are only two samples that have anincreasing regularity pattern, the rest are like fluctuates and/or has no relationship. Based on these results, the natural honeysolution still has a close consistency with the colligative properties of the concentrated solutions so that it can be recommended as anew method in determining the authenticity of honey that has not undergone further processing, remains simple, easy, and inexpensivefor testing.

Abstract

Properties and quality of fibreboard products are much influenced by quality of the fiber materials, pressing process, and the amount and type of the used adhesive. The use of malic acid adhesives in the manufacture of medium density fibreboards (MDF) from mahang wood has low mechanical properties, especially modulus of static value. This paper studies on the effect of adding long fibers of pine wood and petung bamboo to improve the properties of MDF mahang wood with malic acid adhesives. The compositions ratio of mahang wood, pine wood, and petung bamboo fiber are 100/0/0, 90/10/0, 80/20/0, 90/0/10, 80/0/20, and 80/10/0, malic acid content of 25 wt % based on dry weight fibers and hot pressing at 180ºC for 10 minutes. Physical and mechanical tests were accomplished according to JIS 5905-2003 testing standard. Result shows the addition of long fibers of pine wood and petung bamboo increased the mechanical value of MDF from mahang wood. The best mixture of fiber is 90% mahang wood fiber and 10% petung bamboo, with value internal bonding 0.7 MPa, modulus of rupture 9.11 Mpa, and modulus of elasticity 2.5 GPa.
