Penerapan Pembelajaran Biologi Berbasis Macromedia Flash Dan Implikasinya Terhadap Keterampilan Metakognitif Dan Penguasaan Konsep Siswa Kelas VIII SMPN 6 Mataram

: Generally in school, the concept delivery in learning process still relies on verbal language, as the result, student's thinking skills and learning outcome become low. Therefore, audiovisual-based learning is needed to improve student's metacognitive and learning outcome aspects, for example by using Macromedia Flash. This research is aimed to differentiate student's metacognitive skills and concept mastery at grade VIII in SMPN 6 Mataram between students who are taught by Macromedia Flash and students who are taught without using Macromedia Flash. This research is included into pre-experimental and the design was the static-group comparison design. The results of this research showed that: 1) students who were taught by Macromedia Flash had average values for metacognitive skils higher than students who were taught without Macromedia Flash, that were 85.84 and 66.80 respectively. From t-test obtained that there was difference of metacognitive skills between both sample groups; 2) the average values of student's concept mastery in control group was higher than students in experimental group, that were 85.44 and 84.79 respectively. T-test analysis indicated that there was no difference of concept mastery between students who were taught by Macromedia Flash and students who were taught without Macromedia Flash

Factors associated with body weight status among students in infrastructure University Kuala Lumpur (IUKL), Kuala Lumpur, Malaysia

The occurrence of obesity and overweight status in the population has caught public attention. This is in line with the World Health Organization's concern (2013). The present study aimed to determine factors associated with body weight status among students in Infrastructure University Kuala Lumpur (IUKL), Kuala Lumpur, Malaysia. A cross-sectional study was conducted to asses physical activity level, environmental factors affecting physical activity level and their association with body weight status among 280 students in Infrastructure University Kuala Lumpur (IUKL), Kuala Lumpur, Malaysia. The mean of respondent’s total physical activity per week was 3988.50 ± 6758.45 METs minute/week. This was significantly higher (t = 3.020, p = 0.003) among male respondents (5496.37 ± 7860.26 METs minute/week) compared to females (3032.93 ± 5779.55 METs minutes/week). The overall environmental supports for physical activity among the respondents were at moderate level (2.17 ± 0.72), although the total environmental supports for physical activity among female is slightly higher compared to male (2.17 ± 0.77 vs 2.15 ± 0.63), no significant different was observed (t = - 0.25; p = 0.805). In general over weight / obese status was highly prevalent among those with low involvement with neighbourhood environment for physical activity (28%) (the lowest quartile). Although adjusted crude analysis of support to neighbourhood environment for physical activity showed reverse associations with overweight / obese status, no significant trend was observed

Kajian Eksperimen Viscous Form Factor pada Hambatan Kapal Katamaran

Kapal katamaran saat ini banyak menarik perhatian karena memiliki tingkat efisiensi dan performansi hidrodinamika yang lebih baik dibandingkan dengan kapal konvensional (bentuk monohull). Salah satu tantangan yang dihadapi oleh para pakar perkapalan adalah memprediksi secara akurat karakteristik hidrodinamika hambatannya. Makalah ini mengkaji secara eksperimental di kolam tarik (towing tank) untuk mendapatkan nilai viscous form factor pada lambung kapal katamaran pada beberapa variasi kecepatan. Viscous form factor merupakan komponen hambatan yamg penting dalam menghitung hambatan viskos kapal. Model uji adalah katamaran simetris dengan beberapa bervariasi jarak antara lambung. Hasil pengujian di towing tank dibandingkan dengan hasil uji di terowongan angin (wind tunnel). Hasil uji model disajikan dalam bentuk tabel dan grafik dan didiskusikan dengan beberapa hasil kajian para pakar lainnya. Pada penelitian eksperimental ini, hasil yang diperoleh menunjukkan bahwa viscous form factor pada lambung katamaran adalah lebih besar dibandingkan demihull. Fenomena ini menunjukkan adanya efek interaksi hambatan yang ditimbulkan oleh jarak antara lambung. Disamping itu, semakin besar jarak antara lambung maka semakin kecil nilai viscous form factor-nya. Fenomena ini dapat dijadikan masukan bagi para designer dalam memprediksi total hambatan kapal dan selanjutnya menentukan besar daya mesin kapal katamaran secara akurat dan rasiona

Construction Risk Taxonomy: An International Convergence of Academic and Industry Perspectives

Risk management is a topic heavily researched and important for industry professionals. Both academic and industry perspectives are critical to advancing this field, especially in risk identification and taxonomy. A unique comparison and convergence of these perspectives is developed in order to understand the most relevant risks for projects and to ensure they are addressed in the risk management process. This comparison is created via a content analysis of the relevant literature and a survey to industry professionals. The differences and similarities among risks are analyzed, revealing that both perspectives emphasize financial/economic risks. The literature tends to focus on political; acts of God classified risks, whereas the industry places emphasis on regulatory risks. An elaboration of variations is performed aiming to improve the literature-based taxonomy taking into account the industry perspective to ensure its risk management process responds to these risks and provides a clearer focus towards future research

The performance of modified jatropha-based nanofluid during turning process

The industry's extensive use of petroleum-based metalworking fluid (MWF) harms the environment and humans. The production of bio-based MWF, especially from crude jatropha oil (CJO), has therefore taken numerous initiatives. This aimed to formulate newly modified jatropha oil (MJO) with the addition of 0.05wt.% hBN and 0.05wt.% MoS2 as the nanofluid for MWF. The performance of the nanofluids was determined through the turning process in terms of cutting temperature, workpiece surface roughness, tool life and tool wear of the tool lubricated by the nanofluids. The performance of the nanofluid samples was compared with the synthetic ester (SE). From the results, after conducted 100mm axial cutting length MJO+hBN+MoS2 recorded the lowest in cutting temperature and surface roughness compared to all samples. The result shows that MJO+hBN+MoS2 has longer tool life (6500mm) compared to SE (6000mm). Abrasion and adhesion were observed as the dominant tool wear mechanism. In conclusion, MJO+hBN+MoS2 shows better machining performance and has the potential to be an environmentally friendly metalworking fluid
