    ABSTRACT Learning is a complex process that occurs in every person throughout his life. The development of science and technology increasingly encourage renewal efforts in the utilization of technological results in the learning process of teachers required to be able to use the tools that can be provided by the school, and it is possible that these tools in accordance with the development and demands of the times. In a teaching and learning process, two very important elements are teaching methods and multimedia learning. These two aspects are interrelated. Therefore the authors do research on the use of multimedia-based learning resources in learning, especially learning Islamic religious education. The purpose of this study is to know and describe the use of multimedia-based learning resources in learning Islamic Religious Education in SMP Muhammadiyah Al-kautsar Special Program academic year 2016/2017. This research is included in field research by using qualitative descriptive method. Then the data collection method used is, observation, interview and documentation and data analysis using inductive method. Based on the results of research and data analysis, the use of multimedia in learning is very important role on the academic value of student learning, in this case can be seen from the results of student daily re-examination. Before using the multimedia values obtained by the students from the daily test, the student score varies with the lowest average value of the value of the value of 50-65 (E) 65%, 70-80 (C) 25%, 90-95 ( A) 10% while after using the learning process using multimedia result of daily value of student average student who get lowest score 70-75 (C) 65%, value 80-85 (B) 15%, value 90-95 (A) 20% so learning without using the lowest multimedia value of 50 and while the learning using multimedia the lowest value of 70. The learning time used for teaching is not wasted. This is what can make learning time to be effective, and the learning atmosphere to be efficient by using multimedia so that learning is more interesting and interactive.

    A cross-sectional study was conducted to identify the relationship between blood lead concentration and nutritional status among primary school children in Kuala Lumpur. A total of 225 Malay students, 113 male and 112 female, aged 6.3 to 9.8 were selected through a stratified random sampling method. The random blood samples were collected and blood lead concentration was measured by a Graphite Furnace Atomic Absorption Spectrophotometer. The nutrient intake was determined by the 24-hour Dietary Recall method and Food Frequency Questionnaire. An anthropometric assessment was reported according to growth indices (z-scores of weight-for-age, height-for-age, and weight-for-height). The mean blood lead concentration was low (3.4 ± 1.91 ug/dL) and was significantly different between gender. Only 14.7% of the respondents fulfilled the daily energy requirement. The protein and iron intakes were adequate for a majority of the children. However, 34.7% of the total children showed inadequate intake of calcium. The energy, protein, fat and carbohydrate intakes were significantly different by gender, that is, males had better intake than females. Majority of respondents had normal mean z-score of growth indices. Ten percent of the respondents were underweight, 2.8% wasted and 5.4% stunted. Multiple linear regression showed inverse significant relationships between blood lead concentration with children's age (β= -0.647, p<0.001) and per capita income (β=-0.001, p=0.018). There were inverse significant relationships between blood lead concentration with children's age (β=-0.877, p=0.001) and calcium intake (β= -0.011,p=0.014) and positive significant relationship with weight-for-height (β=0.326, p=0.041) among those with inadequate calcium intake. Among children with inadequate energy intake, children's age (β= -0.621, p< 0.001), per capita income (β= -0.001,p=0.025) and protein intake (β= -0.019, p=0.027) were inversely and significantly related with blood lead concentration. In conclusion, nutritional status might affect the children's absorption of lead and further investigation is required for confirmation

    A Novel RSSI Prediction Using Imperialist Competition Algorithm (ICA), Radial Basis Function (RBF) and Firefly Algorithm (FFA) in Wireless Networks

    This study aims to design a vertical handover prediction method to minimize unnecessary handovers for a mobile node (MN) during the vertical handover process. This relies on a novel method for the prediction of a received signal strength indicator (RSSI) referred to as IRBF-FFA, which is designed by utilizing the imperialist competition algorithm (ICA) to train the radial basis function (RBF), and by hybridizing with the firefly algorithm (FFA) to predict the optimal solution. The prediction accuracy of the proposed IRBF–FFA model was validated by comparing it to support vector machines (SVMs) and multilayer perceptron (MLP) models. In order to assess the model’s performance, we measured the coefficient of determination (R2), correlation coefficient (r), root mean square error (RMSE) and mean absolute percentage error (MAPE). The achieved results indicate that the IRBF–FFA model provides more precise predictions compared to different ANNs, namely, support vector machines (SVMs) and multilayer perceptron (MLP). The performance of the proposed model is analyzed through simulated and real-time RSSI measurements. The results also suggest that the IRBF–FFA model can be applied as an efficient technique for the accurate prediction of vertical handover

    Rapid seagrass meadow expansion in an Indian Ocean bright spot

    The areal extent of seagrass meadows is in rapid global decline, yet they provide highly valuable societal benefits. However, their conservation is hindered by data gaps on current and historic spatial extents. Here, we outline an approach for national-scale seagrass mapping and monitoring using an open-source platform (Google Earth Engine) and freely available satellite data (Landsat, Sentinel-2) that can be readily applied in other countries globally. Specifically, we map contemporary (2021) and historical (2000–2021; n = 10 maps) shallow water seagrass extent across the Maldives. We found contemporary Maldivian seagrass extent was ~ 105 km2 (overall accuracy = 82.04%) and, notably, that seagrass area increased threefold between 2000 and 2021 (linear model, + 4.6 km2 year−1, r2 = 0.93, p &lt; 0.001). There was a strongly significant association between seagrass and anthropogenic activity (p &lt; 0.001) that we hypothesize to be driven by nutrient loading and/or altered sediment dynamics (from large scale land reclamation), which would represent a beneficial anthropogenic influence on Maldivian seagrass meadows. National-scale tropical seagrass expansion is unique against the backdrop of global seagrass decline and we therefore highlight the Maldives as a rare global seagrass ‘bright spot’ highly worthy of increased attention across scientific, commercial, and conservation policy contexts

    The shortage of natural aggregates has compelled the developers to devote their efforts to finding alternative aggregates. On the other hand, demolition waste from old constructions creates huge land acquisition problems and environmental pollution. Both these problems can be solved by recycling waste materials. The current study aims to use recycled brick aggregates (RBA) to develop eco-friendly pervious concrete (PC) and investigate the new concrete's structural performance and pore structure distributions. Through laboratory testing and image processing techniques, the effects of replacement ratio (0%, 20%, 40%, 60%, 80%, and 100%) and particle size (4.75 mm, 9.5 mm, and 12.5 mm) on both structural performance and pore feature were analyzed. The obtained results showed that the smallest aggregate size (size = 4.75 mm) provides the best strength compared to the large sizes. The image analysis method has shown the average pore sizes of PC mixes made with smaller aggregates (size = 4.75 mm) as 1.8-2 mm, whereas the mixes prepared with an aggregate size of 9.5 mm and 12.5 mm can provide pore sizes of 2.9-3.1 mm and 3.7-4.2 mm, respectively. In summary, the results confirmed that 40-60% of the natural aggregates could be replaced with RBA without influencing both strength and pore features

    The factors that influence the reading habit among Malaysian: a systematic literature review

    Get PDF
    Reading is an action that a person does to obtain a wider knowledge through his or her experience and this process may lead that person into a very eye-opening self-discovery. In Malaysia, reading habits rate is still at a lower level, Malaysian on average read only two books per year. About 80% of Malaysian university students are reluctant readers. They can read but choose not to read. Therefore, the objective of this study is to identify the factors affecting the reading habit among Malaysia. To answer the research question of this study we performed a systematic literature review (SLR). We defined a mapping study process adapted from existing guidelines to categorize and to structure the research evidence that has been published in the area of reading habits among Malaysian and world-wide. Twenty-Four papers were used in our synthesis of evidence, and five factors were identified. The results of this SLR showed the five factors that can affect the reading habits among Malaysian: (1) Internet (2) Environmental influence (3) Lack of motivation (4) Peer pressure (5) Entertainment. The findings of this SLR would be beneficial for understanding the needs of Malaysian towards the reading habit by looking at the factors, that might be a measurement of reading habit environment in other specific scopes
