ANALISIS PENGARUH MOTIVASI KERJA DAN FAKTOR KOGNISI PEKERJA TERHADAP KEMAMPUAN KERJA SERTA DAMPAKNYA TERHADAP PERFORMANSI KERJA (STUDI KASUS DI PT. SANKEN INDONESIA-BEKASI)

Makalah ini bertujuan untuk memperkirakan berapa besar pengaruh yang diberikan dari variabel Motivasi Kerja dan Kognisi Pekerja terhadap Kemampuan Kerja serta dampaknya terhadap Performansi di PT. SANKEN INDONESIA dengan menggunakan analisis jalur (Path Analysis), dengan tujuan menerangkan akibat langsung dan tidak langsung seperangkat variabel sebagai variabel penyebab (eksogenus) terhadap seperangkat variabel lainnya yang merupakan variabel akibat (endogenus). Berdasarkan pengolahan data dengan menggunakan analisis jalur menunjukkan bahwa pengaruh antara variabel Motivasi Kerja dan Kognisi Pekerja terhadap Kemampuan Kerja memberikan kontribusi sebesar 38 %, sedangkan faktor lain diluar variabel penelitian yang tidak teridentifikasi oleh model penelitian dan dapat mempengaruhi peningkatan serta penurunan Kemampuan Kerja adalah sebesar 62%. Sedangkan pengaruh antara variabel Motivasi Kerja (X1), Kognisi Pekerja (X2) dan Kemampuan Kerja (Y) terhadap Performansi Kerja (Z) adalah sebesar 56%, sedangkan faktor lain diluar variabel penelitian yang tidak teridentifikasi oleh model penelitian dan dapat mempengaruhi peningkatan serta penurunan Performansi Kerja (Z) adalah sebesar 44 %.

New direct alcohol and hydrogen fuel cells for naval and aeronautical applications (PILCONAER)

In the current context of demand for reliable, low cost and low environmental impact energy sources, many countries and companies are mostly focused on fuel cells (FC) in fields as transportation and stationary power generation and portable devices. Lately, FCs have begun to be applied in naval and aeronautical systems due to its high efficiency, low noise and environmental advantages. These applications could range from propulsion systems to auxiliary power units(APU). The main problems associated with the use of FCs in these areas are the current high cost due to the materials used, i.e. Nafion and Pt, the lack of durability testing in these specific conditions, security issues to flammability and high H2 pressures and low availability as a fuel, or the toxicity of methanol used as a fuel, and specific parameters such as weight in aircraft applications and volume in marine applications. Currently it is working on each of these issues, and at this point the ethanol as direct fuel is considered crucial. The use of ethanol as fuel has the advantage of easy transportation, storage and refueling, and is nontoxic. Bioethanol is a promising energy source, produced from raw materials containing sugar or starch. These raw materials exists in all parts of the world and is renewable, which involves the use of local energy sources contributing to the diversification of energy supply, reducing import dependence, increasing security of supply and generating new opportunities for agriculture. The main objective of the project is the development of low power stacks (stacks) fed with methanol (DMFC)and ethanol (DEFC) based on the development of new catalysts and membranes. PILCONAER aims contributing to the development of a sustainable use technology, further commitment to the restoration of the natural environment and biodiversity conservation

Hybrid membranes with improved methanol crossover for DMFCs applications

One of the most studied types of fuel cells is the direct methanol fuel cells (DMFCs). These type of fuel cells are a suitable energy source for low power portable electronic devices as well as backup and light-duty traction applications. In fact, DMFC stack has been successfully used on board an unmanned aerial vehicle. In this work, low cost hybrid organic-inorganic membranes have been prepared via sol-gel chemistry and direct infiltration of a novel zirconia modified phosphosilicate gel (40SiO2-40P2O5-20ZrO2) within the sulfonated polystyrene blocks of sSEBS, in order to achieve an improvement in DMFC performance with respect to Nafion and pristine sSEBS by minimizing methanol crossover
