PENGARUH MOTIVASI KERJA TERHADAP KINERJA PENDIDIK DAN TENAGA KEPENDIDIKAN DI SEKOLAH MENENGAH KEJURUAN NEGERI 1 PALEMBANG

This study uses quantitative research methods, which in processing the data in the form of numbers. In this study, the regression variable (X) of work motivation and variable (Y) of performance aims to determine whether motivation has an effect on the performance of educators and education staff at the state vocational high school 1 Palembang. Motivation at work can have an impact on the performance carried out, this motivation can affect the behavior of each individual at work to get maximum work results. In this study, the data was processed through a questionnaire with the number of respondents totaling 87 people, both from educators and education staff with civil servant and non-civil servant status at SMKN 1 Palembang. The data collection technique uses a questionnaire with a statement of 30 questions. The variables in this study are motivation as the independent variable (X) and performance as the dependent variable (Y). The data collected was then analyzed using a simple linear regression analysis technique by testing the test hypothesis (T) and the coefficient of determination (R2). To prove the decision-making using the SPSS For Windows Version 25 application. Based on the results of the study, it can be concluded that motivation affects the performance of educators and education staff at the Palembang 1 state vocational high school seen from the t-count value (2.965) which is greater than t- table (0.677742) with a significant level of 5% this means that H0 is rejected and Ha is accepted. Meanwhile, the percentage of the effect is 36.9% and the rest is influenced by other factors not examined in this study. Keywords: Work Motivation, Performance

Vitreous haemorrhage: a consequence of herpes simplex acute retinal necrosis

Acute retinal necrosis (ARN) is a rare, blinding disease that typically affects adults. However, in this case report, we highlight the diagnosis, management and outcome of herpes simplex acute retinal necrosis in a 13-year-old healthy girl, who presented with painful right eye, redness and blurring of vision for one week. Examination of the right eye showed features of granulomatous panuveitis. Optic disc was swollen and retina appeared pale. There were multiple patches of retinitis and haemorrhages at mid-periphery of the fundus with inferior serous detachment observed. Rapidly progressive inflammation in just four days along with secondary cataract that obscured fundus view, imposed greater challenge to the diagnosis and management. Intravenous acyclovir 300mg, 3 times a day was initiated promptly while vitreous fluid was sent for polymerase chain reaction, which identified Herpes Simplex Virus-1. Inflammation improved, but she developed vitreous haemorrhage secondary to proliferative retinopathy, which required panretinal photocoagulation. ARN is therefore, principally a clinical diagnosis and high index of suspicion is crucial particularly, in children for prompt diagnosis and treatment. Complications should also be addressed timely to improve the chances of preserving vision

Graphene Oxide Nanocomposite for Sustainable Pure Water by PES Membrane

The urgent concern of water shortage have promoted to the development of different sustainable technologies with the rapid evolution of nanotechnologies. Graphene oxide (GO) is a water-soluble material that can be constructed into a number of structures such as membranes, and has many applications in environmental sectors. Furthermore enhancing membrane characteristics to improve water flux performance and mitigate fouling is crucial issue for membrane separation technology. GO serves as nanofiller to overcome fouling during filtration as well as water flux improvement. This work aimed to develop PES membranes by phase inversion method and the fabricated membranes subjected to series analysis of FESEM, hydrophilicity and water flux. The results showed that the GO improved the contact angle of the pure PES membrane and the water flux increased from 13 to 16 L/m2.h. Therefore, the PES-GO membrane proved its capability to be used for various applications to reduce membrane fouling

Synthesis of iron oxide nanoparticles to enhance polysulfone ultrafiltration membrane performance for salt rejection

The main target of membrane technologies is to provide better filtration and separation of organic and inorganic substance from water as well as for longer life of the membrane. Iron oxide (α-Fe2O3) nanoparticles (NPs) were synthesised by simple sol gel method and characterised using X-ray diffraction (XRD) and transmission electron microscopy (TEM) to show the structure and particle size of the nanoparticles. The α- Fe2O3 NPs with the size of 15 ± 2 nm was blended with Polysulfone (PSf) in lower loading of 0.5 wt% to prepare ultrafiltration (UF) membrane using the wet phase inversion method. The membrane cross section, surface, EDX and mapping were analysed using field emission scanning electron microscopy (FESEM) include EDX analyser. The effect of α-Fe2O3 NPs on membrane properties was determined in terms of permeability, hydrophilicity (contact angle), porosity and pore size. The results of α-Fe2O3 NPs incorporated PSf showed good improvement in the hydrophilicity of the membrane where the contact angle was reduced from 82° to 70°. The pure water flux of α-Fe2O3 NPs-incorporated PSf membrane increased to more than three times compared to the pure PSf membrane. This enhancement of pure flux was due to lower intrinsic membrane resistance and higher pore size. The rejection of salts (sodium chloride (NaCl) and sodium sulfate (Na2SO4)) of the modified membrane was enhanced compared to pure PSf membrane under the same condition. The addition of α-Fe2O3 NPs leads to an improvement of the PSf ultrafiltration membrane properties.The authors would like to gratefully acknowledge NPRP grant # [5-1425-2-607] from the Qatar National Research Fund (a member of Qatar Foundation) and grant No. ICONIC-2013-002 from Universiti Kebangsaan Malaysia for support in this work.

Fabrications of hybrid zinc oxide nanorods -carbon nanotubes cotton

The preparation and characterization of zinc oxide (ZnO) nanostructures on green carbon nanotubes cotton (CNTC) was investigated. CNTC from waste cooking palm oil (WCPO) was synthesized via chemical vapor deposition (CVD) reactor. The CNTC is soft, fluffy, light weight and resembles cotton fiber used in textiles. ZnO nanostructures were grown on CNTC using chemical bath deposition method. It was observed that ZnO nanorods with aspect ratio of 9.32 of were successfully grown on the green CNTC. The combination of ZnO and CNTC hybrid is a promising composite that can be further explored in the application of electromagnetic absorbing material, piezoelectric nanogenerator and sensors
