Analisis faktor dan cabaran pelaksanaan tanggungjawab sosial korporat Islam

Boheran Nudin Azlinda, Mustaffa Che Su, Ahmad Mohd Khairie,

Abstract

Dalam memastikan CSR bercirikan Islam dilaksanakan dengan sebaiknya, faktor dan cabaran menjadi indikator yang harus dipertimbangkan agar pelaksanaannya mengikut garis panduan dan prinsip Islam. Hal ini kerana, pencapaian organisasi Islam yang cemerlang juga dipengaruhi oleh perlaksanaan CSR Islam. Objektif kajian ini memberi tumpuan untuk meneroka faktor dan cabaran pelaksanaan CSR Islam di Bank Islam Malaysia Berhad (BIMB). Kajian ini menggunakan kaedah kualitatif melalui temu bual mendalam dengan sepuluh orang informan yang terdiri daripada pelaksana CSR di BIMB. Hasil kajian mendapati terdapat empat faktor yang menggalakkan BIMB melaksanakan CSR Islam iaitu kesedaran pihak pengurusan, budaya institusi Islam, etika pelaksana CSR dan memenuhi tuntutan masyarakat. Manakala cabaran yang dihadapi untuk melaksanakan CSR Islam adalah dari sudut strategi komunikasi, sumber maklumat, pengurusan sumber manusia dan kewangan..

Coordination chemistry of the benzaldehyde−(1r)−(-)−fenchone azine and derivatives fench=nn=c(h)−c6 h4 x (x = h, cl, br, ome or no2 in the meta or para positions) with palladium

Ahmad Mustaffa, Md Isa Illyas, L. Shaw Bernard, D. Perera Sarath,

Abstract

The benzaldehyde−(1R)−(-)−fenchone azine (1) and derivatives (3), (4), (5), (6) and (7) were prepared by heating the desired benzaldehyde derivatives and fenchone hydrazone in boiling ethanol solution in the presence of acetic acid as catalyst for 3 h. Treatment of the ligands (L) with Na2PdCl4H2O or [PdCl2(NCPh)2] in the ratio of 1 : 1 or 2 : 1 gave the complexes of the type PdL2Cl2 (2), (8), (9), (10), (11) and (12) of which the palladium was bonded to the nitrogen near to fenchone residue. Keywords: Fenchone azine, chiral terpene, palladium complexes..

Kesan pemukulan terhadap pemasukan magnetit (Fe3 O4) ke dalam pulpa kenaf

Ramly Rosazley, Abu Bakar Suriani, Zakaria Sarani, Abdullah Mustaffa, Ahmad Sahrim,

Abstract

Teknologi pemasukan lumen membenarkan partikel-partikel pengisi magnet dimasukkan ke dalam lumen gentian dengan tidak menjejaskan kebersihan permukaan luar daripada pelekatan sebarang pengisi. Aluminium sulfat (alum) dan polietilenamina (PEI) berperanan sebagai pembantu retensi dengan memberikan kesan positif di dalam proses pemasukan lumen. Kajian ini menumpukan kesan pemukulan terhadap pemasukan magnetit (Fe3O4) ke dalam pulpa kenaf menggunakan alat pemukul PFI Mill. Mikroskop elektron imbasan (SEM) digunakan untuk melihat pelekatan partikel pengisi di dalam lumen gentian, manakala mikroskop konfokal digunakan bagi melihat struktur morfologi pulpa pemasukan lumen. Magnetometer sampel bergetar (VSM) pula digunakan bagi pengukuran pemagnetan kertas. Proses pemukulan dapat meningkatkan kadar pemasukan pengisi ke dalam lumen gentian pada resolusi 4000 rpm. Namun begitu, pada pemukulan 8000 rpm kadar pemasukan pengisi menurun...

Syntheses and characterization of the complexes of Molybdenum, Tungsten and Palladium with 2-diacetylpyridine-(1R)-(-)_fenchone azine

Mustaffa Ahmad

Abstract

The diimine 2-diacetylpyridine-(1R)-(-)-fenchone azine {fench=NN=CMe}C5H5N (4) was prepared by heating 2-diacetylpyridine with fenchone hydrazone (3) in boiling ethanol in the presence of acetic acid as the catalyst. Treatment of [Mo(CO)4(nbd)], [Cr(CO)4(nbd)] or [W(CO)4(nbd)] (nbd = norbornadiene) with 2-diacetylpyridine-(1R)-(-)-fenchone azine {fench=NN=CMe}C5H5N (4) gave the five-membered chelated N,N bonded carbonylcomplex of (5), (6) or (7), respectively. Treatment of [PdCl2(NCPh)2] with the azine ligand (4) gave the palladium-complex (8). Treatment of (8) with LiBr or NaI gave the metathesis product of (9) or (10), respectively. Treatment of [{(_3-2-MeC3H4)PdCl2}2] with the azine ligand (4) gave the chloride salt which was then isolated as the corresponding PF6 salt (11). Keywords Molybdenum complexes, tungsten complexes, palladium complexes, bidentate N-N ligand complexes, fenchone azine ligand complexes..

Complexes of 2,6_diacetylpyridine-di-(1R)_(-)_fenchone diazine (fench=NN=CMe)2C5H5N) ligand with molybdenum, tungsten or palladium

Mustaffa Ahmad

Abstract

The Schiff_base ligand 2,6_diacetylpyridine_di_(1R)_(-)_fenchone diazine (9) was prepared by heating 2,6_diacetyl_pyridine (7) and fenchone hydrazone (8) in boiling ethanol in the presence of acetic acid as the catalyst for 28 h. Treatment of (9) with [Mo(CO)4(nbd)] or [W(CO)4(nbd)] in benzene at 80 0C gave the tetracarbonylmolybdenum(0) (10) or tetracarbonyltungsten(0) (11). The complexes (10) and (11) showed that the diazine (9) acted as a bidentate chelating ligand bonded through the pyridyl nitrogen and only one of the imino nitrogen donor atoms of the ligand involved in the bonding. However, diazine (9) acted as a planar terdentate N,N,N_donor_ligand when reacted with palladium(II) to give the cationic products of (12), (13) and (15), respectively. Keywords Molybdenum complexes, tungsten complexes, palladium complexes; bidentate- N,N ligand complexes, terdentate-N,N,N ligand complexes, fenchone azine ligand complexes..
