Kualiti dan keberkesanan bimbingan manasik bagi jemaah haji Daerah Bintan Kepulauan Riau Indonesia

Ibadah haji merupakan rukun kelima dalam rukun Islam yang menjadi kewajiban keatas umat Islam yang mampu mengerjakannya. Namun, didapati sebahagian dari bakal jemaah tidak dapat memahami modul bimbingan akibat dari pada tenaga pengajar yang kurang berkelayakan. Oleh itu kajian ini adalah untuk menilai sistem bimbingan yang berkesan untuk jemaah haji dan mencadangkan kerangka bimbingan yang berkualiti dan berkesan. Kajian ini merupakan reka bentuk Exploratory sequential iaitu reka bentuk pembangunan instrument dan kerangka. Tujuan reka bentuk ini adalah untuk meramalkan penemuan kualitatif kepada sampel yang lebih besar.Ia mendapatkan 8 orang pakar temu bual dan 120 orang responden. Hasil kajian menunjuk sistem bimbingan manasik haji sedia ada berada pada tahap sederhana. Kajian ini telah mencadangkan satu kerangka bimbingan yang berkualiti dan berkesan bagi memastikan ibadah haji tersebut mencapai matlamat yang ditetapkan syariat. Implikasi kajian menunjukkan kerangka bimbingan manasik haji yang dihasilkan dapat membantu kepada pembimbing manasik dan bakal jemaah dalam meningkatkan tahap kefahaman dalam melaksanakan ibadah ini

Green tea polyphenol-reduced graphene oxide: derivatisation, reduction efficiency, reduction mechanism and cytotoxicity

This paper reports on the derivatisation, reduction efficiency, reduction mechanism and cytotoxicity of green tea polyphenol-reduced graphene oxide (GTP-RGO). The reduction of graphene oxide (GO) at 90°C using a weight ratio (WR) of GTP/GO=1 resulted in the production of a stable GTP-RGO dispersion in aqueous media, as indicated by the results of ultravioletvisible (UV-Vis) spectroscopy, Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA) and the measurement of zeta potential and electrophoretic mobility. In addition, the results from UV-Vis spectroscopy and X-ray photoelectron spectroscopy (XPS) analysis indicated the comparable reduction ability of GTP relative to the standard reducing agent, hydrazine (N2H4). The removal mechanism of epoxy group from GO via reduction reaction with GTP was investigated by implementing hybrid functional method of Becke-3-parameters-Lee-Yang-Parr (B3LYP)using Gaussian 09 software. The energy and frequency calculations showed that the GO reduction using GTP was more spontaneous and relatively took place faster than the reduction using N2H4, as evidenced by higher entropy change (ΔS) (0.039 kcal/mol·K) and lower Gibbs free energy (ΔG) barrier (58.880 kcal/mol).The cytotoxicities of GO and GTP-RGO samples were evaluated against human colonic fibroblasts cells (CCD-18Co). The GO sample was determined to be toxic even at low concentration (6.25 μg/mL), while the GTP-RGO sample possesses notably low toxicity at the same concentration. The cell culture experiments revealed that the incorporation of GTP led to a decrease in the toxicity of GTP-RGO samples

Distortion of Infall Regions in Redshift Space-I

We show that spherical infall models (SIMs) can better describe some galaxy clusters in redshift slice space than in traditional axially-convolved projection space. This is because in SIM, the presence of transverse motion between cluster and observer, and/or shear flow about the cluster (such as rotation), causes the infall artifact to tilt, obscuring the characteristic two-trumpet profile; and some clusters resemble such tilted artifacts. We illustrate the disadvantages of applying SIM to convolved data and, as an alternative, introduce a method fitting a tilted 2D envelope to determine a 3D envelope. We also introduce a fitting algorithm and test it on toy SIM simulations as well as three clusters (Virgo, A1459, and A1066). We derive relations useful for using the tilt and width-to-length ratio of the fitted envelopes to analyze peculiar velocities. We apply them to our three clusters as a demonstration. We find that transverse motion between cluster and observer can be ruled out as sole cause of the observed tilts, and that a multi-cluster study could be a feasible way to find our infall toward Virgo cluster

Magnetic-field effects on photon-induced quantum transport in a single dot-cavity system

In this study, we show how a static magnetic field can control photon-induced electron transport through a quantum dot system coupled to a photon cavity. The quantum dot system is connected to two electron reservoirs and exposed to an external perpendicular static magnetic field. The propagation of electrons through the system is thus influenced by the static magnetic and the dynamic photon fields. It is observed that the photon cavity forms photon replica states controlling electron transport in the system. IF the photon field has more energy than the cyclotron energy, then the photon field is dominant in the electron transport. Consequently, the electron transport is enhanced due to activation of photon replica states. By contrast, the electron transport is suppressed in the system when the photon energy is smaller than the cyclotron energy.Comment: 5 Figures, 6 Page

Redesigning Power Strip With Case Study: Security Information Use Of Products

There are 212 cases of fire from 2015-2018 that have occurred by electricity failure in Bandung City, those failures happen because of power strip misused by users. The power strip has a certain maximum electric current input from electric devices, misused happen when the electric devices that connect have exceeded the electrical current of the power strip. This situation can cause a fire because of the power strip overheat. From 50 user 68% of users do not know the maximum electric current that can be delivered by a certain power strip and 32% of users knowing the maximum electric current but do not know how to use it for everyday use. These research aims are to redesign security of use certain power strip, focus on user habit and user interface information. Keywords Product Development, Power Strip, Security of Us

Model of Empowerment to Improve Autonomy Directly Observed Treatment (DOT) Tuberculosis Patients

Empowerment as not yet optimal health promotion efforts done to enhance the autonomy of Directly Observed Treatment (DOT), which affect the success of the recovery of patients with pulmonary tuberculosis. The purpose of research was to develop a model empowerment based on Health Promotion and Health Literacy with approach to nursing intervention in an effort enhance the autonomy of the DOT - pulmonary TB patients. The method was an observational analytic with cross sectional approach. Multistage random sampling was DOT-pulmonary TB patients to decide the district and simple random sampling was assigned to choose the participants, a total of 253 DOT- pulmonary TB patients new case with acid resistant bacilli positive on the advanced phase in this study. The study conducted in five districts in Surabaya City (center, north, south, east and west). Data were collected by questionnaire on variables namely personal, cognitive and affective, nursing intervention, commitment, family supports, health literacy and DOT- autonomy. Structural Equation Modeling (SEM) with LISREL is used for constructing predictive model. Result : This study found a new model which was developed based on combination of Health Promotion Model (HPM) and Health Literacy (HL). Statistical result confirm that personal, cognitive and affective, health literacy and family support considered as important factors in improving DOT-autonomy. Conclusion : DOT- autonomy will improve by considering four main factors, personal, cognitive and affective, health literacy, family support. This model can be adapted by District Health Office Surabaya City as the main actor regional health development. In addition, this model may become a reference for other district in improving their nursing intervention in community setting
