Cabaran pelajar antarabangsa di Kolej Kediaman UTHM

Setiap pelajar mempunyai pelbagai cabaran tersendiri semasa mereka mengikuti pengajian di peringkat universiti. Cabaran ini terpaksa dilalui oleh mereka dan besar kemungkinan ianya akan mempengaruhi pencapaian akademik pelajar. Oleh sebab itu, kajian ini dilakukan untuk mengenal pasti masalah dominan yang dihadapi oleh pelajar antarabangsa yang tinggal di Kolej Kediaman UTHM. Masalah penyesuaian yang dikaji meliputi akademik, sosial dan peribadi-emosi. Selain itu, kajian ini dijalankan untuk mengenal pasti tahap keselesaan interaksi dalam kalangan pelajar antarabangsa. Perbezaan antara masalah yang dihadapi dengan ciri-ciri demografi juga turut dikaji. Kajian berbentuk tinjauan deskriptif dan inferensi ini menggunakan borang soal selidik sebagai instrumen di mana ia melibatkan 98 orang pelajar antarabangsa yang tinggal di Kolej Kediaman UTHM. Data yang diperoleh telah dianalisis menggunakan pendekatan Rasch Model melalui perisian Winstep versi 3.69. Hasil kajian mendapati (i) masalah penyesuaian sosial dilihat sebagai masalah dominan yang dihadapi oleh pelajar antarabangsa dengan nilai mean measure 0.18 logit; (ii) tahap keselesaan interaksi dalam kalangan pelajar antarabangsa pula berada pada tahap sederhana dengan nilai skor min 2.70; (iii) tiada perbezaan yang signifikan antara masalah penyesuaian akademik dengan CPA; (iv) tiada perbezaan yang signifikan antara masalah penyesuaian sosial dengan CPA; (v) tiada perbezaan yang signifikan antara masalah penyesuaian peribadi-emosi dengan CPA; (vi) tiada perbezaan yang signifikan antara masalah penyesuaian akademik dengan negara; (vii) tiada perbezaan yang signifikan antara masalah penyesuaian sosial dengan negara; (viii) terdapat perbezaan yang signifikan antara masalah penyesuaian peribadi-emosi dengan negara. Diharap maklumat daripada tulisan ini akan memberikan kesedaran dan manfaat bagi semua mengenai isu berkaitan dengan cabaran pelajar antarabangsa untuk kesejahteraan warga dan organisasi

Electro-oxidation of Ethanol on Carbon Supported PtSn and PtSnNi Catalysts

Even though platinum is known as an active electro-catalyst for ethanol oxidation at low temperatures (< 100 oC), choosing the electrode material for ethanol electro-oxidation is a crucial issue. It is due to its property which easily poisoned by a strong adsorbed species such as CO. PtSn-based electro-catalysts have been identified as better catalysts for ethanol electro-oxidation. The third material is supposed to improved binary catalysts performance. This work presents a study of the ethanol electro-oxidation on carbon supported Pt-Sn and Pt-Sn-Ni catalysts. These catalysts were prepared by alcohol reduction. Nano-particles with diameters between 2.5-5.0 nm were obtained. The peak of (220) crystalline face centred cubic (fcc) Pt phase for PtSn and PtSnNi alloys was repositioned due to the presence of Sn and/or Ni in the alloy. Furthermore, the modification of Pt with Sn and SnNi improved ethanol and CO electro-oxidation. Copyright © 2016 BCREC GROUP.
