Pandemi Covid-19 tidak menyurutkan minat mahasiswa untuk mendapatkan layanan dari perpustakaan. Tujuan penelitian  adalah mengembangkan dan mendeskripsikan kelayakan instrument pengukuran respon mahasiswa  berdasarkan ARCS (Attention, Relevance,  Confidence, Satisfaction) terhadap layanan perpustakaan selama masa pandemi covid-19. Penelitian pengembangan dilaksanakan di UPT Perpustakaan Universitas Lambung Mangkurat Tahun Akademik 2019/2020. Tahapan penelitian model 4D dikembangkan oleh Thiagarajan. Four-D model ini terdiri dari pendefinisian (define), tahap perancangan (design), tahap pengembangan (develop), dan tahap ujicoba (disseminate). Kelayakan instrument yang digunakan dilihat dari data validitas. Validitas instrumen diukur dengan menggunakan lembar validasi kemudian ditentukan berdasarkan validasi oleh pakar yang dinyatakan dengan Valid atau tidak valid. Jika valid, akan dikategorikan kembali menjadi sangat baik, baik, cukup, kurang, dan sangat kurang baik. Proses validasi dilaksanakan oleh tiga orang validator. Kesimpulan dari artikel ini adalah instrument pengukuran respon mahasiswa  berdasarkan ARCS (Attention, Relevance,  Confidence, Satisfaction) terhadap layanan perpustakaan selama masa pandemi covid-19 layak digunakan dalam penelitian. Dengan demikian instrumen ini dapat di implementasikan untuk diuji coba lebih lanjut pada tahap diseminasi.

Pembelajaran tematik adalah metode pembelajaran yang menekankan pemberian tema khusus pilihan untuk mengajarkan beberapa konsep kurikuler Konsep integrasi beberapa subjek untuk mengajar di sekolah Indonesia, secara umum bukan hal baru dan tidak sukses pada masa lalu. Sebagai tambahan, beberapa orang menanggap pembelajaran tematik adalah satu kesempatan sementara sebagian lain memandang bahwa ini memiliki masalah. Namun, jawaban untuk bagaimana penerapan pembelajaran tematik belum dikaji secara menyeluruh. Riset ini menyusun desain pembelajaran tematik untuk membimbing siswa sekolah dasar dalam memperoleh literasi saintifik, mengggunakan pendekatan R&D model 4-D yang direduksi menjadi 3 tahap yaitu: define, design, dan develop. Luaran riset ini adalah desain pembelajaran tematik untuk membimbing siswa sekolah dasar dalam memperoleh literasi saintifik, yang keabsahan dan keandalan dalam kategori dapat digunakan.

Thematic Learning

It is requisite that each activity is necessary to have a clear purpose as it was designed to be a well applicable plan. Scientific literacy indicates that science has value outside scientific practice is hardly modern idea and reality, although we lose sight of this history. Unfortunately, PISA study at 1999-2015 and several preexist works has shows that common science teachings don’t optimally guide students to achieve scientific literacy. As matter of fact, the answer to how to guide student achieving scientific literacy has not been obtained yet. By proposing this work, I am consider that thematic learning as an alternative method to guide students on achieving scientific literacy. Thematic learning is an educational method of teaching in which emphasis is given on choosing a specific theme for teaching concepts. It is based on integrating various information and use it to demonstrate the topic. Pedagogy of thematic learning is based on its exploration of broad areas in one theme. I don’t deny that the concept of integrating subjects to teach in Indonesian schools, generally is not new and has not been very successful in the past. In addition, some people consider thematic learning as an opportunity while others view it as having problems. The answer, however, to how thematic learning education implementation has not been studied yet comprehensively. Therefore, thematic learning lesson plans is very important to be designed then implemented. This work constructs lesson plan to guide primary education student on achieving scientific literacy, using R&D approach four-D model: define, design, develop, and disseminate. It gained lesson plan completed by student worksheets also assessment tests as well, that validated by experts and practitioners nor reliability counted based exclusively on test.

Expert Validation

The lack of Biology teaching materials in senior high school in the Kerinci District has promoted this research. The purpose of this development research is to produce e-modules as teaching materials used by students in Biology subjects. The model used in developing this e-module is the 4-D model, which consists of 4 stages, namely defining, designing, developing, and disseminating. Biology e-modules on plantae and animalia material based on the potential of the Kerinci region were validated by media and material experts. The results of the media expert validation obtained the final percentage of 90% (very valid category) and the material expert validation obtained a percentage of 75% (valid category). From the results of the field test, the teacher responded that the e-modules produced were suitable for use in biology class X high school learning with a percentage of 92.5% (very good category). Furthermore, e-module trials on students obtained responses that the products produced were also proper to be used in biology learning in class X of senior high school. The small group test obtained a score of 85% (excellent category) and the large group test obtained score 78.3% (good category). The use of the developed e-modules in learning resulted in a score of 76.3% (successful category).

Systemic Arterial Tree

A distributed model of the human arterial tree including all main systemic arteries coupled to a heart model is developed. The one-dimensional (1-D) form of the momentum and continuity equations is solved numerically to obtain pressures and flows throughout the systemic arterial tree. Intimal shear is modeled using the Witzig-Womersley theory. A nonlinear viscoelastic constitutive law for the arterial wall is considered. The left ventricle is modeled using the varying elastance model. Distal vessels are terminated with three-element windkessels. Coronaries are modeled assuming a systolic flow impediment proportional to ventricular varying elastance. Arterial dimensions were taken from previous 1-D models and were extended to include a detailed description of cerebral vasculature. Elastic properties were taken from the literature. To validate model predictions, noninvasive measurements of pressure and flow were performed in young volunteers. Flow in large arteries was measured with MRI, cerebral flow with ultrasound Doppler, and pressure with tonometry. The resulting 1-D model is the most complete, because it encompasses all major segments of the arterial tree, accounts for ventricular-vascular interaction, and includes an improved description of shear stress and wall viscoelasticity. Model predictions at different arterial locations compared well with measured flow and pressure waves at the same anatomical points, reflecting the agreement in the general characteristics of the “generic 1-D model” and the “average subject” of our volunteer population. The study constitutes a first validation of the complete 1-D model using human pressure and flow data and supports the applicability of the 1-D model in the human circulation.

Abstract Extra dimensions have proven to be a very useful tool in constructing new physics models. In earlier work, we began investigating toy models for the 5-D analog of the kinetic mixing/vector portal scenario where the interactions of dark matter, taken to be, e.g., a complex scalar, with the brane-localized fields of the Standard Model (SM) are mediated by a massive U(1)D dark photon living in the bulk. These models were shown to have many novel features differentiating them from their 4-D analogs and which, in several cases, avoided some well-known 4-D model building constraints. However, these gains were obtained at the cost of the introduction of a fair amount of model complexity, e.g., dark matter Kaluza-Klein excitations. In the present paper, we consider an alternative setup wherein the dark matter and the dark Higgs, responsible for U(1)D breaking, are both localized to the ‘dark’ brane at the opposite end of the 5-D interval from where the SM fields are located with only the dark photon now being a 5-D field. The phenomenology of such a setup is explored for both flat and warped extra dimensions and compared to the previous more complex models.
