Sistem Pembelajaran Berbasis Terknologi Informasi dan Komunikasi

Sistem pembelajaran yang terorganisir merupakan perpaduan yang meliputi unsur manusia, materi, fasilitas, peralatan, dan prosedur yang berinteraksi untuk mencapai suatu tujuan. Elemen manusia dalam sistem pembelajarannya adalah mahasiswa, guru, dosen, pustakawan, laboratoriun, administrasi personal serta pihak-pihak yang mendukung keberhasilan proses pembelajaran. Informasi dan teknologi komunikasi merupakan hasil rekayasa manusia terhadap proses informasi dan proses penyampaian pesan(gagasan) dari satu pihak ke pihak yang lain yang mengakibatkan dalam distribusi yang lebih cepat, lebih luas, dan penyimpanan yang lebih lama. Untuk dapat memanfaatkan TIK untuk meningkatkan kualitas pembelajaran, ada tiga hal yang harus di wujudkan yaitu : (1) siswa dan guru harus memiliki akses keteknologi digital dan internet dikelas, sekolah, dan lembaga pendidikan guru. (2) harus tersedia materi kualitas, dukungan bermakna dan budaya bagi siswa dan guru. (3) guru harus memiliki pengertahuan dan keterampilan dalam menggunakan alat dan sumber daya digital untuk membantu siswa mencapai standar akademik. Tuntutan pembelajaran kedepan harus terbuka, dua arah, beragam, multi disiplin dan terkait dengan produktivitas kerja``pada saat itu`` dan kompetitif. Teknologi informasi dan komunikasi yang murah dan mudah akan menghilangkan keterbatasan ruang dan waktu yang selama ini membatasi dunia pendidikan. Pada saat ini banyak dampak yang terjadi akibat perkembangan IT jika disikapi secara positif mampu memberikan dampak positif, namun jika ditanggapi negatif dan mungkin akan terpengaruh secara negatif

Effect of Different Levels of Nano-selenium on Performance, Blood Parameters, Immunity and Carcass Characteristics of BroilerChickens

The aim of the present study was to test the hypothesis that nano- seleniuminclusion in broilers’ diets can improve productivity and metabolic functions of broilers.Feed and water were provided ad libitum. A total of 180 one-day old male Ross 308 chicks were randomly assigned to six groups based on a completely randomized design, each with three replicates of 10 birds. One of the groups served as the control (CON) and was given a basal diet without further dietary supplementation, whereas the other five groups were offered the same starterandgrower diets further supplemented with dietary nano-selenium (NS) at 0.1 mg/kg of feed (NS1), 0.2 mg/kg of feed (NS2), 0.3 mg/kg of feed (NS3), 0.4 mg/kg of feed (NS4), and 0.5 mg/kg of feed (NS5). Nano-selenium dietary supplementation significantly improved weight gain and feed conversion ratio in starter (1st-21st day), grower (22nd-42nd day) and whole (1st-42nd) periods of experiment (P0.05). While, albumin levels in blood were decreased and anti-Newcastle disease hemagglutination-inhibition titer was increased after the dietary supplementation with the nano-selenium (P< 0.05). As conclusion, the current study demonstrated that the supplementation of nano-selenium in broiler diets could improve growth performance, carcass components and immune function, without negative effects on internal organs, and other carcass parameters and gastrointestinal parts

Marketing Communications for Tourism Development in Ecoethno Leadcamp Site

Tourism is a critical sector for national, regional, and rural development, providing job opportunities and increasing income for communities, governments, and private sectors. The success of tourism development requires integrated marketing communications that showcase the natural and socio-economic potential of the region, including its tourist attractions. This study examines the marketing communications strategy of Ecoethno Leadcampsite, a camping ground-based tourist spot in Pangalengan, Bandung Regency, West Java Province. The study used a qualitative case study method with data collected through direct observation, interviews, Focus Group Discussions (FGD), and documentation. The results reveal that Ecoethno Leadcampsite's marketing communications strategy for tourism development is successful in establishing public relations by empowering the surrounding community to become partners, direct marketing, personal selling, and sales promotion with Word of Mouth to fellow tourists and partners, including the use of social media. The study also suggests that Ecoethno Leadcampsite can increase collaboration with educational institutions by developing educational-based tourism or tourism locations in nature conservation, socio-economic, culture, and character building that is creative, productive, and innovative

The Incremental Cooperative Design of Preventive Healthcare Networks

This document is the Accepted Manuscript version of the following article: Soheil Davari, 'The incremental cooperative design of preventive healthcare networks', Annals of Operations Research, first published online 27 June 2017. Under embargo. Embargo end date: 27 June 2018. The final publication is available at Springer via http://dx.doi.org/10.1007/s10479-017-2569-1.In the Preventive Healthcare Network Design Problem (PHNDP), one seeks to locate facilities in a way that the uptake of services is maximised given certain constraints such as congestion considerations. We introduce the incremental and cooperative version of the problem, IC-PHNDP for short, in which facilities are added incrementally to the network (one at a time), contributing to the service levels. We first develop a general non-linear model of this problem and then present a method to make it linear. As the problem is of a combinatorial nature, an efficient Variable Neighbourhood Search (VNS) algorithm is proposed to solve it. In order to gain insight into the problem, the computational studies were performed with randomly generated instances of different settings. Results clearly show that VNS performs well in solving IC-PHNDP with errors not more than 1.54%.Peer reviewe

Sleep patterns and habits in high school students in Iran

<p>Abstract</p> <p>Background</p> <p>Sleep patterns and habits in high school students in Iran have not been well studied to date. This paper aims to re-address this balance and analyse sleep patterns and habits in Iranian children of high school age.</p> <p>Methods</p> <p>The subjects were 1,420 high school students randomly selected by stratified cluster sampling. This was a self-report study using a questionnaire which included items about usual sleep/wake behaviours over the previous month, such as sleep schedule, falling asleep in class, difficulty falling asleep, tiredness or sleepiness during the day, difficulty getting up in the morning, nightmares, and taking sleeping pills.</p> <p>Results</p> <p>The mean duration of night sleep was 7.7 h, with no difference between girls, boys, and school year (grade). The mean time of waking in the morning was not different between genders. About 9.9% of the girls and 4.6% of the boys perceived their quality of sleep as being bad, and 58% of them reported sleepiness during the day. About 4.2% of the subjects had used medication to enhance sleep. The time of going to bed was associated with grade level and gender. Sleep latency was not associated with gender and grade leve, l and 1.4% experienced bruxism more than four times a week.</p> <p>Conclusion</p> <p>Our results are in contrast with that of previous studies that concluded sleep duration is shorter in Asia than in Europe, that boys woke-up significantly later than girls, and that the frequency of sleep latency category was associated with gender and grade level. The magnitude of the daytime sleepiness, daytime sleepiness during classes, sleep latency, and incidences of waking up at night represent major public health concerns for Iran.</p

Past Achievements and Future Challenges in 3D Photonic Metamaterials

Photonic metamaterials are man-made structures composed of tailored micro- or nanostructured metallo-dielectric sub-wavelength building blocks that are densely packed into an effective material. This deceptively simple, yet powerful, truly revolutionary concept allows for achieving novel, unusual, and sometimes even unheard-of optical properties, such as magnetism at optical frequencies, negative refractive indices, large positive refractive indices, zero reflection via impedance matching, perfect absorption, giant circular dichroism, or enhanced nonlinear optical properties. Possible applications of metamaterials comprise ultrahigh-resolution imaging systems, compact polarization optics, and cloaking devices. This review describes the experimental progress recently made fabricating three-dimensional metamaterial structures and discusses some remaining future challenges
