PENGARUH MEDIA PEMBELAJARAN MIND MAPPING TERHADAP MINAT BELAJAR PESERTA DIDIK PADA PELAJARAN EKONOMI KELAS XI IPS 1 di SMA NEGERI 27 BANDUNG

Judul penelitian ini adalah pengaruh media pembelajaran mind mapping terhadap minat belajar peserta didik pada pelajaran ekonomi kelas XI IPS 1 di SMA Negeri 27 Bandung tahun ajaran 2016-2017. Berdasarkan tinjauan langsung di SMA Negeri 27 Bandung kelas XI IPS 1, Pembelajaran konvensional (ceramah) hanya membuat peserta didik kurang aktif dan malas dalam menerima materi yang ada, karena pembelajaran hanya terpusat pada apa yang disampaikan sehingga tidak dapat dimengerti secara maksimal. Tujuan dari penelitian ini adalah: (1) Mengetahui penggunaan media mind mapping pada mata pelajaran ekonomi kelas XI IPS 1 di SMA Negeri 27 Bandung. (2) Mengetahui minat belajar peserta didik pada mata pelajaran ekonomi kelas XI IPS 1 di SMA Negeri 27 Bandung. (3) Mengetahui seberapa besar pengaruh media mind mapping terhadap minat belajar peserta didik pada mata pelajaran ekonomi kelas XI IPS 1 di SMA Negeri 27 Bandung. Metode yang digunakan dalam penelitian ini adalah survei. Teknik pengumpulan data yang digunakan yaitu observasi dan angket dengan teknik pengolahan data uji validitas, uji reliabilitas, uji normalitas data, analisis regresi linier sederhana dan koefisien determinasi, Hipotesis penelitian berbunyi “Terdapat pengaruh antara media pembelajaran mind mapping (X) terhadap minat belajar peserta didik (Y) pada mata pelajaran ekonomi. Hasil penelitian ini adalah terdapat pengaruh antara variabel X dan Variabel Y sebesar 0,336 atau 33,60%. Untuk mengetahui hubungan fungsional antara variabel X dan variabel Y maka digunakan analisis regresi linier sederhana dengan hasil perhitungan sebagai berikut : Y = 9.915 + 0.537 X artinya bahwa setiap media pembelajaran mind mapping bertambah 9,915 maka minat belajar meningkat sebesar 0,537. Untuk mengetahui seberapa besar pengaruh variabel X (media pembelajaran mind mapping) terhadap variabel Y (minat belajar), maka digunakan koefisien determinasi dengan hasil perhitungan sebesar 33,60% maka sebagian lainnya ditentukan oleh faktor lain yang tidak diteliti. Kesimpulan hipotesis penelitian dapat diterima, sebagai akhir penelitian penulis menyampaikan saran kepada guru agar sebaiknya guru menggunakan variasi media pembelajaran yang menarik berkaitan dengan materi pelajaran yang akan disampaikan, karena cara ini dapat membuat peserta didik aktif dan kreatif untuk belajar. Kepada para praktisi atau peneliti lain di bidang pendidikan dapat melakukan penelitian serupa dengan media pembelajaran dan metode yang berbeda agar diperoleh berbagai alternatif untuk peningkatan pemahaman pembelajaran pada pokok bahasan selanjutnya dan kepada pihak sekolah sebagai bahan kajian bagi sekolah dan menyarankan guru untuk menggunakan media pembelajaran yang mampu meningkatkan prestasi belajar peserta didik untuk mendukung pendekatan saintifik dan media pembelajaran yang baik. Kata Kunci : media pembelajaran mind mapping, minat Belajar

RICORS2040 : The need for collaborative research in chronic kidney disease

Chronic kidney disease (CKD) is a silent and poorly known killer. The current concept of CKD is relatively young and uptake by the public, physicians and health authorities is not widespread. Physicians still confuse CKD with chronic kidney insufficiency or failure. For the wider public and health authorities, CKD evokes kidney replacement therapy (KRT). In Spain, the prevalence of KRT is 0.13%. Thus health authorities may consider CKD a non-issue: very few persons eventually need KRT and, for those in whom kidneys fail, the problem is 'solved' by dialysis or kidney transplantation. However, KRT is the tip of the iceberg in the burden of CKD. The main burden of CKD is accelerated ageing and premature death. The cut-off points for kidney function and kidney damage indexes that define CKD also mark an increased risk for all-cause premature death. CKD is the most prevalent risk factor for lethal coronavirus disease 2019 (COVID-19) and the factor that most increases the risk of death in COVID-19, after old age. Men and women undergoing KRT still have an annual mortality that is 10- to 100-fold higher than similar-age peers, and life expectancy is shortened by ~40 years for young persons on dialysis and by 15 years for young persons with a functioning kidney graft. CKD is expected to become the fifth greatest global cause of death by 2040 and the second greatest cause of death in Spain before the end of the century, a time when one in four Spaniards will have CKD. However, by 2022, CKD will become the only top-15 global predicted cause of death that is not supported by a dedicated well-funded Centres for Biomedical Research (CIBER) network structure in Spain. Realizing the underestimation of the CKD burden of disease by health authorities, the Decade of the Kidney initiative for 2020-2030 was launched by the American Association of Kidney Patients and the European Kidney Health Alliance. Leading Spanish kidney researchers grouped in the kidney collaborative research network Red de Investigación Renal have now applied for the Redes de Investigación Cooperativa Orientadas a Resultados en Salud (RICORS) call for collaborative research in Spain with the support of the Spanish Society of Nephrology, Federación Nacional de Asociaciones para la Lucha Contra las Enfermedades del Riñón and ONT: RICORS2040 aims to prevent the dire predictions for the global 2040 burden of CKD from becoming true

About the functional test of permanent faults in distributed systems

The effects of permanent faults, arising along working life of digital electronic systems, may impact their reliability and performance. In-field test may help to detect these faults and to prevent serious effects in safety-critical applications. Distributed electronic systems introduce further complexity in this scenario, as the low observability and the lack of maintenance make difficult the detection as well as the identification of failing elements and their repairing. Functional workloads are often used for on-line tests of distributed systems to detect permanent faults. Suitable techniques for test generation and early identification of functionally untestable permanent faults are critical issues that are faced in this wor

Reducing SEU Sensitivity in LIN Networks: Selective and Collaborative Hardening Techniques

Digital electronic systems in automotive applications are in charge of different tasks, ranging from very critical control functions (e.g., airbag, ABS, ESP) to comfort services (e.g., handling of mirrors, seats, windows, wipers). Hardening these systems involves suitably trading off cost and reliability. Due to standards and regulations in the area, the reliability of subsystems involved even in the least critical applications has to be evaluated, and in most cases hardening has to be performed with very low extra cost. In this work, two approaches are proposed for hardening the LIN bus, which implements a serial communication network typically used in low-throughput and low-cost sub-systems in automotive applications. First, critical elements in LIN nodes are identified and some techniques to harden them are proposed following a selective hardening approach. Secondly, collaborative hardening techniques are proposed for reducing global sensitivity in a LIN network built with commercial devices, trying to achieve a high degree of robustness in the network with low cost solutions. We report some experimental results allowing evaluating the hardware cost and the robustness of the proposed technique
