Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

A study of the optimization of the TDY 150D/96F yarn production process parameters located at PT X has been conducted. In the process of making yarn, tenacity and filament force are some of the response variables that must be controlled to ensure the quality of the yarn meets the specified specifications. Draw ratio and temperature are input variables that will affect both response variables. Experiments were carried out using the L16 Taguchi orthogonal array with parameters, draw ratio and temperature. The draw ratio parameter uses the limits of 1: 1.23, 1: 1.30, 1: 1.40 and 1: 1.55. While the temperature parameters used are 150°C, 160°C, 170°C and 180°C. This study aims to obtain the optimum tenacity and filament force values from a combination of set process parameters. This optimization method has succeeded in improving the value of tenacity and filament force that consistently meets specifications. The highest average Tenacity value of DTY 150D/96F reaches 4.22 g/den, while the highest average filament force value of DTY 150D/96F reaches 6.55 N. For both parameters given, draw ratio is the parameter that gives the highest impact on tenacity and filament force with S/N ratio respectively 12.09 and 12.31. This result is expected to be used to develop DTY 150D/96F yarn quality in other significant aspects
In the event of natural or manmade disaster, clean water might be a very precious commodity. Commercial water treatment tablet might be able to purify water but it might also poses health hazard when consumed in large amount. This research focused on the development of naturally derived water treatment tablet formed from the leaves and oil extracted from the seeds of Moringa Oleifera and activated carbon (from coconut shells). The characterization of the activated carbon and Moringa Oleifera was carried out by Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD) and Brunauer, Emmett and Teller (BET), while the efficiency of water treatment tablet was analysed by Turbidity Meter. FTIR results shows that there are hydroxyl groups and carboxylic group in the activated carbon sample which correlates well with literatures. XRD results indicated that both activated carbon and Moringa Oleifera was amorphous in structure which might facilitates towards the dynamicity of the water treatment process. BET’s results shows that activated carbon have larger surface area compared to Moringa Oleifera leaves. The results obtained from turbidity meter analysis showed that the existence of Moringa Oleifera oil contributes toward better water treatment capability while the leaves of Moringa Oleifera on its own was less effective as water treatment agent. It can be concluded that the combination of Moringa Oleifera oil and leaves with activated carbon at a ratio of 125:50:250 (in mg) can be considered effective in removing impurities from water where 59.22% of the contaminant was successfully removed
