This article explored the potential of using palm fruit shells to make briquettes as an alternative fuel for both domestic and industrial use. This will significantly reduce the problem of deforestation and excessive dependence on fossil fuels and reduce the impact of greenhouse gas emissions generated by trees as a fuel for wood. Cassava starch was used in an amount of 100:15 by weight and the burning properties of the produced palm fruit briquettes were determined. The combustion characteristics of the palm fruit briquettes produced are 7.56% average moisture, 17.45% average volatiles, 6.68% average ash, 68.28% average bound carbon and 9717.74 kcal /kg of average calorific value. These results, compared with the literature, showed that briquettes made from palm husks have good combustion properties, which makes them suitable for domestic applications and small industries.

Optimization mathematical model of the V-belt drive was constructed. The power output of the belt drive was modeled and optimized by the Response Surface Methodology (RSM). Analysis of variance was used to evaluate the extent of influence of each independent variables on the power output response of the belt drive. A RSM optimization process was proposed to calculate optimal power output for V-belt drive given a set of pulley diameter for the drive employed in a tilling machine. The analysis showed that optimum power output of the drive for workshop light operation machinery could be obtained at driving and driven pulley radius range of 550-900 mm and 250-500 mm. An optimum power output of 1418.76 kW was obtained at driving and driven pulley radius of 846 and 486 mm respectively for a farm tilling machine.

The system equation of motion is analyzed to determine the main body velocities used for the system variables without introducing rotational coordinates or the turning effect of the system follower on the beater. Discontinuities in the velocity are observed when an impact force results from the beat-up action of the beater on the weft-yarn. Formulation between the velocity jump and displacement is presented for the system response. The impact phenomenon is characterized by the rise in the system velocity resulting from the vibration propagation through the system. The velocity is observed to increase as the system displacement response increases. This is typical of a high speed mechanism of this type mostly used in the textile industry if not controlled.

The process and machine capability indices were measured to determine the process and machine adequacy for industrial application. The tolerance limits were obtained from the given nominal size of the shaft, using the basic hole system and 90 sample shafts were turned on the lathe machine to specification for varying spindle speed and feed rate of the lathe. Three (3) samples were randomly selected for the turning process of a combination of the spindle speed and feed rate as a subgroup size for a total subgroup of thirty (30). The diameters (representing the quality characteristics) were used to generate control charts and capability histogram for the process. The process is within statistical control but found incapable of meeting up to specification because the capability index (Cp) measured was less than 1 and the machine capability for industrial application is not adequate.
