Fossil fuel reserve throughout the world was projected to only last for 40 years for oil, 60 years for natural gas and 20 decades for coal. This projection has prompted alternative energy researchers to advance into renewable energy. Among most manufactured solar cells, The Dye sensitized solar cell is in the 3rd generation of the family. This paper presents the fabrication of Dye sensitized solar cell with dye from Keriang and Pucuk merah fruit. The TiO2 electrode with a thickness of 10 µm is used to immersed into the dye. The cell was tested under a solar simulator with standard test condition. The results show that the Keriang dye has the photo to electrical efficiency of 1.16 % while the Pucuk Merah dye shows 0.89%. The data shows that the bonding of anthocyanin pigment in particular the carboxyl and hydroxyl group to the TiO2 molecules were successful.

Kelingkan is an art of embroidery using metal ribbon threads coated with gold, silver embroidered on a soft fabric surface. Kelingkan requires high precision and uses the expertise of embroiders. Recall this is the handcraft led by Malay women for a long time in nature, namely Malays in Sarawak, Kelantan and Selangor. Each of these states has a different design motif identity and reflects its own state and identity through the use of flora and fauna motifs. In Kelantan, the art of embroidery is still done on a small scale although it is less well known Sarawak and Selangor but the market demand still continues due to the uniqueness of the edge decoration (kok) different between the states that are active in Kelingkan embroidery. The question is what is the origin of Kelantan embroidery and how is the decorative motif (kok) depicted in Kelantan embroidery? To answer this question, a qualitative study was conducted through field study methods, Such as observation of dry embroidery artifacts and interviews with embroidery markers. The study found that a history of embroidery kelingkan in Malaysia evolved since the existence of the trading system in Malaya. Only three states Sarawak, Selangor and Kelantan still have embroiders that are actively conducing it. The development of kelingkan embroidery in Malaysia started in the palace and developed through hereditary family relationships and incubator program while there are two side decorative motifs (kok) depicted in Kelantan kelingkan embroidery, namely 3 points and 5 points or also known as etok is shell. In conclusion, the results of this study should be seen as a continuing source for the Malay community art treasures to be preserved and maintained at the younger generation so that no time wasted. Through this study, kelingkan embroidery can also explain the variety of kelingkan available in Malaysia, Kelantan, Selangor and Sarawak which are still actively doing this embroidery in textile and clothing.

Researchers paid attention on career satisfaction as predictor of turnover intention in response to request for future study about antecedent of turnover intention. This study determined the relationship between career satisfaction and turnover intention among the Malaysian information and communication technology (ICT) employees. This study also contributed to the Social Exchange Theory (SET) literature in examining the relationship between career satisfaction and turnover intention. This study used simple random sampling approach to collect data from 214 ICT employees from several organizations in Selangor, Malaysia. SPSS 23 statistical software is used to test the formulated hypotheses. This study revealed empirical findings on negatively significant relationship between career satisfaction and turnover intention. This study offered practically guidance on managerial side in ICT organizations to pay more attention on development of new skills, promotion chances and career goal of ICT employees after understanding the predictor of turnover intention. Therefore, it is expected that turnover intention decreased as career satisfaction increased; while, lack of Malaysian ICT employees’ problem is thought out as well retaining those top performers in the industry.

This paper focuses on an experimental investigation on the dispersion stability of 60:40 water and ethylene glycol based Al2O3−CuO hybrid nanofluids. The volume and concentration of hybrid nanofluids were set to be 30 ml and 0.5%. Three different surfactants (PVP, CTAB, and SLS) with different surfactant ratios (1:10 and 5:10) were used to ensure the nanofluids remained homogenous for a longer period. Dispersion stability is studied using several methods such as sedimentation observation, zeta potential, and UV-Vis. FESEM testing is conducted to study the morphological behavior of the nanoparticles powder, including particle size and structure. Visual inspection showed that only pure Al2O3-CuO and Al2O3-CuO-PVP (1:10) remained homogenous without any visible separation layer. As for UV-Vis spectroscopy, the absorbance value for all samples was below than 1%. Thus, to further investigate the stability Al2O3-CuO hybrid nanofluid, the Zeta potential test is also conducted. Analysis of Zeta potential indicated that PVP with surfactant ratio 1:10 provided better result on the nanofluid stability. The pH value for sample with the PVP dispersant is then measured to be 7.7 which is slightly further from the IEP (pH 9.7-10)
