Inviting someone to be able to study according to a predetermined plan is not easy, especially after the covid-19 pandemic, many children are lazy in learning, especially reading, so teaching materials are needed that can attract students' interest. For junior high school students who still want to play dominantly, the teacher must be able to provide teaching materials in which there is an element of play so that students can be motivated in learning. Based on this background, the researchers conducted a Development Research on Puzzle-based LKPD to improve the science learning outcomes of class VIII SMPN 15 Mukomuko students on the material of the Human Circulatory System. The puzzle that the researcher means is a crossword puzzle. From the results of research and testing from the validator team, researchers got a Puzzle-based worksheet that can be used after the validator team's assessment of the presentation aspect with a value of 18 on the criteria 72% is in the category of quite valid and suitable for use with minor revisions, and the content aspect with a value of 23 on the 76% criteria are in the valid category and suitable for use without revision. From this research we get a reference that can be used by science subject teachers to teach material on the human circulatory system. ABSTRAKMengajak seseorang untuk bisa belajar sesuai dengan rencana yang sudah ditetapkan bukanlah hal yang mudah, apalagi setelah pandemi covid-19, banyak anak yang malas dalam belajar terutama membaca, sehingga diperlukan bahan ajar yang dapat menarik minat siswa. untuk siswa SMP yang masih dominan ingin bermain maka guru harus dapat menyediakan bahan ajar yang didalamnya ada unsur bermain sehingga siswa dapat termotivasi dalam belajar. Berdasarkan latar belakang tersebut peneliti melakukan Penelitian Pengembangan teradap LKPD berbasis Puzzle untuk meningktkan hasil belajar IPA siswa kelas VIII SMPN 15 Mukomuko pada materi Sistem Peredaran Darah manusia. Puzzle yang peneliti maksud adalah teka-teki silang. Dari hasil penelitian dan pengujian dari tim Validator peneliti mendapatkan LKPD berbasis Puzzle yang dapat digunakan setelah penilaian dari tim validator terhadap aspek sajian dengan nilai 18 pada kriteria 72% berada pada kategori cukup valid dan layak digunakan dengan revisi kecil, dan aspek Isi dengan nilai 23 pada kriteria 76% berada pada kategori valid dan layak digunakan tanpa revisi.dari penelitian ini kita mendapatkan sebuah referensi yang dapat digunakan oleh guru mata pelajaran IPA untuk mengajarkan materi sistema peredaran darah manusia.

Microbots have been considered powerful tools in minimally invasive medicine. In the last few years, the topic has been highly studied by researchers across the globe to further develop the capabilities of microbots in medicine. One of many applications of these devices is performing surgical procedures inside the human circulatory system. It is expected that these microdevices traveling along the microvascular system can remove clots, deliver drugs, or even look for specific cells or regions to diagnose and treat. Although many studies have been published about this subject, the experimental influence of microbot morphology in hemodynamics of specific sites of the human circulatory system is yet to be explored. There are numerical studies already considering some of human physiological conditions, however, experimental validation is vital and demands further investigations. The roles of specific hemodynamic variables, the non-Newtonian behavior of blood and its particulate nature at small scales, the flow disturbances caused by the heart cycle, and the anatomy of certain arteries (i.e., bifurcations and tortuosity of vessels of some regions) in the determination of the dynamic performance of microbots are of paramount importance. This paper presents a critical analysis of the state-of-the-art literature related to pulsatile blood flow around microbots.

(1) Background: Simulation-based training (SBT) is the practice of using hands-on training to immerse learners in a risk-free and high-fidelity environment. SBT is used in various fields due to its risk-free benefits from a safety and an economic perspective. In addition, SBT provides immersive training unmatched by traditional teaching the interactive visualization needed in particular scenarios. Medical SBT is a prevalent practice as it allows for a platform for learners to learn in a risk-free and cost-effective environment, especially in critical care, as mistakes could easily cause fatalities. An essential category of care is human circulatory system care (HCSC), which includes essential-to-simulate complications such as cardiac arrest. (2) Methods: In this paper, a deeper look onto existing human circulatory system medical SBT is presented to assess and highlight the important features that should be present with a focus on extracorporeal membrane oxygenation cannulation (ECMO) simulators and cardiac catheterization. (3) Results: A list of features is also suggested for an ideal simulator to bridge the gap between medical studies and simulator engineering, followed by a case study of an ECMO SBT system design. (4) Conclusions: a collection and discussion of existing work for HCSC SBT are portrayed as a guide for researchers and practitioners to compare existing SBT and recreating them effectively.
