Kajian keagamaan, etika kerja Islam, niat untuk kekal dan tingkah laku menyimpang pekerja beragama Islam

Deviant behavior is the behavior that violates organizational norms, thus becoming a threat and has negative impacts on employees and the organizations. This study examined the influence of religiosity and Islamic work ethics on deviant behavior in the organization, and the influence of the mediator, intention to stay, on the relationship between religiosity, Islamic work ethics and deviant behavior. 217 questionnaires were distributed to the respondents involved in this study. However, only 122 questionnaires were returned and used for further analysis. Then, factor analyses were performed on each of the variables. There are four dimensions in deviant behavior: personal aggression, sabotage and destructive action on organization, abuse of time and organization resources, and misappropriation for personal interests. Meanwhile, religiosity consists of three dimensions, namely highly religious behavior, belief and faith, and sacrifice. Islamic work ethics is divided into two dimensions known as diligent and moral responsibility. There are two dimensions such as, affective intention to stay and normative intention to stay in the variables of intention to stay. Multiple regression analysis was used to test the entire hypothesis. The findings showed that the dimensions of highly religious behavior, sacrifices and moral responsibility have significant and negative effects on several dimensions of deviant behavior. Furthermore, the findings revealed that normative intention to stay plays a partial mediator’s role in the relationship. The Theory of Planned Behavior was used as the underpinning theory for the theoretical framework. The limitations of this study were the small number of respondents and the perspectives of Islam. Therefore, it is recommended that future researchers conduct studies with a higher number of respondents and examine the relationship with other religions

Facile fabrication of superhydrophobic and superoleophilic green ceramic hollow fiber membrane derived from waste sugarcane bagasse ash for oil/water separation

Green ceramic hollow fiber membranes with superhydrophobic and superoleophilic surfaces (ss-CHFM/WSBA) were successfully fabricated via facile sol–gel process using tetraethoxysilane (TEOS) and methyltriethoxysilane (MTES) as precursors. In this work, silica solution was prepared using the modified Sto¨ber method. This process was followed by dipping the pristine membranes into the sol–gel solution at various grafting times (0–90 min), grafting cycles (0–4 cycles), and calcination temperatures (400–600⁰ͦC). The wettability, surface morphology, and chemical composition of the pristine and ss-CHFM/WSBA membranes were investigated. The results showed that increasing the grafting time has increased the wettability of ss-CHFM/WSBA with high contact angle of up to 163.9⁰. Similarly, increasing grafting cycle has enhanced the hydrophobicity of ss-CHFM/WSBA due to the formation of hierarchical structure of grafting cycle which were more than one. The optimum calcination temperature for ss-CHFM/WSBA was identified. It was found that increasing the calcination temperature has degraded the sol template on the surface of ss-CHFM/WSBA, hence decreasing the wettability. The preliminary performance tests showed that ss-CHFM/WSBA grafted at 60 min, 3 cycles, and calcined at 400 ⁰C showed excellent oil/water separation efficiency of 99.9% and oil flux of 137.2 L/m2 h

Influence of Polyethylene Glycol Additive on Performance of Polysulfone and Polyethersulfone Membrane

This paper focuses on the performance of polysulfone (PSf) and polyethersulfone (PES) ultrafiltration membranes with polyethylene glycol (PEG). The aim of this study is to determine the effect of PEG as an additive in producing PSf and PES membrane. The flat sheet membranes were prepared via a phase inversion method in which the casting dope solution consists of polysulfone and polyethersulfone separately as polymer, while N-methyl-2-pyrrolidone is used as the solvent material. PEG 400 was used as a pore forming additive in the casting dope solution. The morphology of membranes was analyzed by scanning electron microscopy. The performance of membranes was evaluated in terms of pure water flux (PWF) and humic acid rejection. The effect of different concentrations of PEG additive exhibits significant improvement on PSf and PES membrane performance. The results indicated that PES ultrafiltration membrane exhibits better performance in PWF than does PSf membrane. It was found that the pure water flux increases as the PEG concentration increases (0 to 8 wt%) in casting solution. As a result, the morphology of membranes prepared with a high concentration of PEG has a larger pore size. It can be concluded that PES ultrafiltration membrane consisting of PEG 400 yields an excellent increase in pure water flux compared to PSf membrane

Impact of primary kidney disease on the effects of empagliflozin in patients with chronic kidney disease: secondary analyses of the EMPA-KIDNEY trial

Background: The EMPA KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. Methods: EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. Findings: Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5–2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62–0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16–1·59), representing a 50% (42–58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). Interpretation: In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Effects of water as non-solvent additive on performance of polysulfone ultrafiltration membrane

In this work, polysulfone ultrafiltration membranes were prepared via simple phase inversion with distilled water as non-solvent additive. The main reason for the addition of water in polysulfone dope solution preparation was to enhance the membranes structure. In the dope, 15 wt. % of polysulfone was used and water was varied up to 6 wt. %. The effects of water on morphology, porosity and tensile properties were investigated in detail. From the porosity test, results showed that the addition of water has improved membrane porosity up to 53 %. The FESEM images revealed that membrane morphology has also been modified. However, the tensile properties of membrane decreased as water content increased which may be due to the porosity interaction between polysulfone/NMP with water

Studies on fouling by natural organic matter (NOM) on polysulfone membranes: effect of polyethylene glycol (PEG)

Polysulfone membranes were prepared via phase inversion technique by using polyethylene glycol with molecular weights of 400, 1500 and 6000 Da as pore forming agent in dope formulation. The performance of membrane was characterized using humic acid and water sample taken from Sembrong River, Johor, Malaysia was used as natural organic matter sources. Membrane properties were also characterized in terms of mean pore radius, pure water flux, humic acid rejection and fouling resistance. The results indicated that the pure water flux and mean pore radius of membranes increased with the increase of PEG content. Fourier transform infrared spectroscopy results revealed the presence of hydrophilic component in PSf/PEG blend with the significant appearance of O-H peak at 3418.78 cm(-1). Scanning electron microscopy analysis revealed the presence of finger-like structure for all membranes and the structure intensified as PEG content was increased. The results obtained from the fouling study indicated that the membrane with the lowest PEG content and molecular weight has an excellent performance in mitigating fouling
