Five combustible mixtures of automotive gas oil and dual purpose kerosene were obtained from a retail outlet and blended into different automotive gas oil (AGO) and dual purpose kerosene (DPK) proportions (85:15, 75: 25, 50:50, 25:75 & 15:85% (v/v)). Samples were analyzed using densitometer, hydrometer, karl fischer titrator, pour and cloud point tester based on American Standard for Testing and Materials (ASTM) with the aim of delimiting the degree to which adulteration affects the quality of the pure sample, impact on the environment as well as the effects on compression ignition engines. Results obtained from the analyses of the blended ratios show the following parameters in the ranges; density (0.858–0.827g/cm3); specific gravity@60 0F (0.859–0.828), kinematic viscosity (4.800–1.200 cSt), cloud point (7.000–2.000 oC), pour point (-15.000 – < -34.000 oC) and moisture content (500.000–1200.000 ppm). Results of the analyses showed that 85 % dual purpose kerosene in the blended mixture fell below American Standard for testing and materials (ASTM) and Department for Petroleum Resources (DPR) acceptable standard in terms of viscosity. A maximum of 15% dual purpose kerosene in the blended mixture fell within ASTM specification in terms of moisture content. Specific gravity, density, cloud point and pour point of all the bended samples were within specification. Adulterating automotive gas oil with dual purpose kerosene at (≥ 15:85 %) AGO:DPK ratio as well as the use of biomass as an alternative source of energy due to diversion of dual purpose kerosene for adulteration, results in the release of various types of harmful poly aromatic hydrocarbons to the environment through the exhaust of diesel engines and cooking respectively. It can also lead to reduction in compression ratio, power loss as well as wear and tear of engine parts.

Abstract. Chaerani N, Sudrajat DJ, Siregar IZ, Siregar UJ. 2019. Growth performance and wood quality of white jabon (Neolamarckia cadamba) progeny testing at Parung Panjang, Bogor, Indonesia. Biodiversitas 20: 2295-2301. The aim of this study was to evaluate the genetic parameters of growth and wood quality in white jabon progeny test at 54 months old in Parung Panjang, Bogor. The 105 half-sib families obtained from 12 provenances were evaluated in a randomized complete block design with five replications. Wood quality was assessed both in a non-destructive way using a pilodyn and by destructive method using wood sample taker. Results indicated that the mean value ranged from 5.10 to 10.15 m for height, 6.67 to 15.30 cm for diameter, 2.30 to 3.62 cm for pilodyn penetration, 0.66 to 0.82 g/cm3 for wood density, 0.33 to 0.50 for specific gravity, and 66 to 111 % for moisture content, respectively. There were significant differences among 105 families for all traits except moisture content. The high heritability estimate was found for height (0.4-0.69) and basic density (0.27-0.59). Applying 80% selection intensity on diameter and leaving 84 best families in each block will produce a high total genetic gain. Pilodyn penetration had negative correlation with diameter, wood density, and specific gravity.

Used Vegetable Oil

Biodiesel is a fuel produced from renewable resources; it is a clean alternative fuel, which has drawn the attention of energy researchers for the last two decades due to the disturbing effect of climate change caused by diesel fuel. This paper focuses on showcasing the qualities of biodiesel produced from used vegetable oil and the positive impact on the alarming change in climate today. This paper presents an experimental investigation on production of biodiesel from used vegetable oil (UVO) gotten from a road side bean cake (akara) seller. The oil that was intended to be thrown out was de-odoured and filtered to remove impurities. The filtered oil was then used for biodiesel production and characterized with physical and fuel properties such as density, viscosity, cloud point, refractive index, specific gravity, ash content, moisture content, flash point and cloud point. The results obtained were afterwards compared to ASTM (American Society for Testing and Materials) and EN (Europe’s) international standards. Two biodiesels samples were produced at different temperatures but the same timings. The biodiesel were produced at 700C at 40mins (biodiesel A) and 1000C at 40mins (biodiesel B) with values of specific gravity (0.98 kg/m3; 0.90 kg/m3), density (936kg/m3; 882kg/m3), kinematic viscosity (1.5mm/s2; 5.5 mm/s2), cloud point (150C; 20C), flash point (2600C min; 2000C min), moisture content (0.07%; 0.04%), refractive index (1.4609; 1.4398) and ash point (0.24%; 0.01%) respectively. On comparison, biodiesel A couldn’t match up to the international standards while biodiesel matched up to the standards given.

The production of glucose syrup from cassava starch using acid hydrolysis was carried out in this work. The analysis was based on the preservation of the produced glucose syrup using sodium bisulfite (NaHSO3). The concentration of the preservative was varied from 0.0ppm-30.0ppm (where ppm stands for amount of preservative in a million pert of sample). The ability of the preservative (sodium bisulfite) to sustain the shelf life of glucose syrup was investigated by studying its effects on the physiochemical properties (pH, moisture content, pour point, viscosity, specific gravity, and refractive index) of the glucose syrup. Four (4) different runs of experiment were performed within sixty-four (64) days, during which the physiochemical properties were closely monitored. Sample B1 which contain no sodium bisulfite could not retain the physiochemical properties. Sample B2 contain 5ppm of the preservative in the glucose syrup and shows a little stability of the physiochemical properties. The preservative ability of the sodium bisulfite on the glucose syrup was improved upon as the concentration in part per million increased (i.e from sample B3 to sample B4, from sample B4 to sample B5, in that order etc.). The optimum preservative ability was reached at sample B5 (which has 20.0ppm concentration of sodium bisulfite.) as the physiochemical properties was relatively maintained. Samples B6 and B7 (which have 25.0 and 30.0 part per million respectively) also show a stable preservative abilities. These samples that contain higher concentrations of sodium bisulfite after the optimum (that is, samples B6 andB7) which also yield stable preservative properties, should be discouraged because their intake could lead to health hazards, and the optimum preservative concentration should be encouraged.(That is, sample B5).

Trees planted from agroforestry practices can become valuable resources in meeting the wood requirements of many nations. Gliricidia sepium is an exotic species introduced to the agricultural sector in Malaysia mainly for providing shade for cocoa and coffee plantations. This study investigates its wood physical properties (specific gravity and moisture content) and fibre morphology (length, lumen diameter and cell wall thickness) of G. sepium at three intervals according to age groups ( three, five and seven years of ages). Specific gravity (0.72) was significantly higher at seven years ofage as compared to five (0.41) and three (0.35) years age group with a mean of 0.43 (p<0.05). Mean moisture content was 58.3% with no significant difference existing between the tree age groups. Fibre diameter (22.4 mm) was significantly lower (p<0.05) for the trees which were three years of age when compared to five and seven years age groups (26.6 mm and 24. 7 mm), respectively. Means of fibre length, lumen diameter and cell wall thickness were 0.83 mm, 18.3 mm, and 6.2 mm, respectively, with no significant differences detected between trees in all age groups. Further calculation on the coefficient of suppleness and runkel ratio suggest that wood from G.sepium may have the potential for insulation board manufacturing and paper making. However, future studies should experiment the utilisation of this species for these products to determine its full potential.
