MEMBANGKITKAN KOMPETENSI IR 4.0. PADA GURU SEKOLAH DASAR MELALUI PELATIHAN SINGKAT PEMANFAATAN DIGITAL

The digital age drives change in many sectors of life. In this age, correspondence between two continents happens immediately, and knowledge is exchanged and expended rapidly. Teachers as a focal figure in the realm of instruction are required to redress and even decipher these progressions as a methods for facilitating students to secure the 21st century capabilities. In any case, actually, a large number of teachers are hesitant to connect with these changes, particularly those related with the utilization of innovation in instruction and learning. In some developing countries, for example, Indonesia, a great deal of teachers are frustrated with the digital gap, less expertise in applying technology, limited supporting infrastructure, and students’ age variation. This article investigates the impact of short training on digital technology use in education to 29 primary teachers in Jakarta, Indonesia. The training course includes the introduction of the materials on digital learning, followed by assignment of looking for learning resources on the web, and an essay writing as the assessment to finish of the program. The observations and interviews with 7 respondents showed that the activity of the training improved the teachers’ digital literacy, especially in the utilization of technology in education. Era digital menyebabkan perubahan yang signifikan disetiap lini kehidupan. Pada masa ini komunikasi antar dua benua terjadi seketika, realitas dimodifikasi dan dikonsumsi secara cepat. Guru sebagai sosok sentral dalam dunia pendidikan dituntut untuk mengimbangi bahkan menerjemahkan perubahan tersebut sebagai sarana menghasilkan peserta didik yang memiliki kompetensi abad 21. Namun pada kenyataanya banyak guru yang segan bersinggungan dengan perubahan ini, khususnya yang berkaitan dengan pemanfaatan teknologi dalam pembelajaran. Di beberapa Negara berkembang seperti Indonesia banyak guru yang frustasi karena adanya jurang digital yakni kurang terampil dalam mangaplikasikan teknologi, terbatasnya sarana-prasarana yang mendukung, dan adanya perbedaan usia dengan para peserta didik. Artikel ini mengeksplorasi implikasi dari pelatihan dan pengembangan keterampilan menggunakan teknologi digital yang diberikan kepada 29 guru sekolah dasar di Jakarta, Indonesia. Pelatihan dilaksanakan selama 2 hari pada bulan Juni 2019, diawali dengan penyajian materi, praktik mencari sumber pembelajaran melalui internet kemudian dilanjutkan dengan pemberian evaluasi berupa soal uraian. Berdasarkan hasil observasi dan wawancara dengan 7 orang guru diketahui bahwa pelatihan yang diberikan berdayaguna dalam meningkatkan literasi digital guru untuk memanfaatkan teknologi dalam pendidikan

Peran Mahasiswa dalam Menanamkan Nilai-Nilai Moderasi Beragama di Lingkungan Kampus

Indonesia merupakan sebuah negara kepulauan yang masyarakatnya memiliki beraneka ragam budaya meliputi perbedaan budaya, agama, ras, bahasa, suku, tradisi, dan lain-lain. Sehingga menyikapi hal ini diperlukan toleransi dalam memahami semua perbedaan yang ada. Oleh karena itu, moderasi beragama sangat tepat digunakan dalam kehidupan berbangsa dan bernegara terutama pada kalangan mahasiswa. Moderasi beragama merupakan jalan tengah dalam menghadapi perbedaan baik kelompok ekstrim maupun fundamental. Peran mahasiswa dengan keilmuan yang dimiliki, diharapkan dapat menjunjung tinggi nilai toleransi serta sebagai pelopor untuk mengedukasi masyarakat terkait moderasi beragama. Mahasiswa sangat diperlukan untuk mensosialisasikan dan mengembangkan moderasi beragama masyarakat guna mewujudkan kerukunan dan kedamaian. Untuk mewujudkan moderasi beragama dapat dilakukan dengan saling merangkul dan mengedepankan nilai-nilai toleransi antar umat beragama. Moderasi beragama merupakan kunci terpeliharanya toleransi dan kerukunan, baik tingkat lokal, nasional maupun global. Menolak ekstremisme dan liberalisme dalam beragama adalah kunci keseimbangan, demi terpeliharanya peradaban dan terciptanya perdamaian. Dengan cara inilah masing-masing umat beragama dapat saling menghormati, menerima perbedaan, serta hidup bersama dalam damai dan harmoni. Penelitian ini dilakukan karena penyebaran paham-paham ekstrem, liberal, serta intoleran tidak hanya mengarah pada masyarakat umum saja, melainkan kalangan pelajar serta mahasiswa juga menjadi sasaran empuk dalam penyebarannya. Dikarenakan mahasiswa yang berusia relatif muda yang masih dalam tahap mencari jati diri, dan rendahnya pengetahuan keagamaan mahasiswa sehingga mudah terpengaruh terhadap paham-paham tersebut. Penelitian ini merupakan penelitian dengan pendekatan kualitatif. Teknik pengumpulan data menggunakan metode observasi, wawancara, dan dokumentasi. Dari hasil analisis peneliti maka diperoleh kesimpulan bahwa upaya yang dilakukan dalam membentuk sikap moderasi beragama mahasiswa di kampus yakni dengan cara memberikan pendalaman pengetahuan agama, selektif terhadap tenaga pengajar, dan akomodatif terhadap budaya lokal. Hal ini sesuai dengan hasil wawancara serta observasi peneliti terkait kegiatan-kegiatan yang dilakukan

Effects of the size of cosmological N-Body simulations on physical quantities -- I: Mass Function

N-Body simulations are a very important tool in the study of formation of large scale structures. Much of the progress in understanding the physics of galaxy formation and comparison with observations would not have been possible without N-Body simulations. Given the importance of this tool, it is essential to understand its limitations as ignoring these can easily lead to interesting but unreliable results. In this paper we study the limitations due to the finite size of the simulation volume. We explicitly construct the correction term arising due to a finite box size and study its generic features for clustering of matter and also on mass functions. We show that the correction to mass function is maximum near the scale of non-linearity, as a corollary we show that the correction to the number density of haloes of a given mass changes sign at this scale; the number of haloes at small masses is over estimated in simulations. This over estimate results from a delay in mergers that lead to formation of more massive haloes. The same technique can be used to study corrections to other physical quantities. The corrections are typically small if the scale of non-linearity is much smaller than the box-size. However, there are some cases of physical interest in which the relative correction term is of order unity even though a simulation box much larger than the scale of non-linearity is used. Within the context of the concordance model, our analysis suggests that it is very difficult for present day simulations to resolve mass scales smaller than 100 solar masses accurately and the level of difficulty increases as we go to even smaller masses, though this constraint does not apply to multi-scale simulations.Comment: 10 pages, 6 figure, MNRAS format.

Shape Optimisation of Curved Interconnecting Ducts

Practical ducting layout in process plants needs to satisfy a number of on-site constraints. The search for an optimal flow path around the obstructions is a multi-parameter problem and is computationally prohibitively expensive. In this study, authors proposed a rapid and efficient methodology for the optimal linkage of arbitrarily oriented fluid flow ducts using a single-parameter quadratic/cubic Bézier curves in two/three dimensions to describe the centreline of the curved duct. A smooth interconnecting duct can then be generated by extruding the duct face along the curve. By varying the parameter either along the angular bisector or along the axes of the ducts, a family of Bézier curves is generated. Computational fluid dynamics simulations show that the relationship between pressure drop and the adjustable parameter is a unimodal curve and the optimal connecting duct is the one which has the least pressure drop while satisfying on-site constraints can be used for linking the ducts. The efficacy of the method is demonstrated by applying it to some cases of practical interest.Defence Science Journal, Vol. 65, No. 4, July 2015, pp. 300-306, DOI: http://dx.doi.org/10.14429/dsj.65.8353

Deactivation and regeneration of Ni catalyst during steam reforming of model biogas: An experimental investigation

his paper presents detailed study of biogas reforming. Model biogas with different levels of H2S is subjected to reforming reaction over supported Ni catalyst in a fixed bed reactor at 700 °C and 800 °C. In order to understand the poisoning effects of H2S the reactions have been initially carried out without H2S in the feed stream. Three different H2S concentrations (20, 50 and 100 ppm) have been considered in the study. The H2O to CH4 ratio is maintained in such as way that CO2 also participates in the reforming reaction. After performing the poisoning studies, regeneration of the catalyst has been studied using three different techniques i) removal of H2S from the feed stream ii) temperature enhancement and iii) steam treatment. Poisoning at low temperature is not recoverable just by removal of H 2S from the feed stream. However, poisoning at high temperature is easily reversed just by removal of H2S from the feed stream. Unlike some previous reports by Li et al. (2010) and Rostrup-nielsen (1971) [1,2], catalyst regeneration is achieved in shorter time frames for all the regeneration techniques attempte
