The main priority of providing education during Covid-19 pandemic to prioritize health and safety of students, educators, education staff, families, and the community in general, as well as considering the growth of the students and their psycho social conditions. The continuity of teaching and learning process that is not carried out in the school has potential to have a long lasting negative impact. Anticipating the negative consequences and issues of distance learning, SMA Negeri 1 Kota Depok, according to government guidelines, has implemented two new policies for limited Face-to-face learning and an emergency curriculum ( under special conditions). During the Covid-19 pandemic, online and offline learning must be done side by side. On the other hand the student learning outcomes are expected have good final result. The writer conducted Classroom Action Research as an effort to improve students' learning outcomes during the Covid-19 pandemic by using Blended Learning method which combine Face-to face learning method with distance learning. Based on the cycle 1 and cycle 2, there were found that Blended learning can improve students' learning outcomes in Mathematics subject for 12 graders of Science subject at SMAN 1 Kota Depok.
ABSTRAKPrioritas utama penyelenggaraan pendidikan pada masa pandemi Covid–19 adalah untuk mengutamakan kesehatan dan keselamatan peserta didik, pendidik, tenaga kependidikan, keluarga, dan masyarakat secara umum, serta mempertimbangkan tumbuh kembang peserta didik dan kondisi psikososial. Kelangsungan belajar mengajar yang tidak dilakukan di sekolah berpotensi menimbulkan dampak negatif yang berkepanjangan.

Abstract. This paper presents a new sampling head design and the method used to evaluate it. The elemental composition of aerosols collected by two different
sampling devices in a semi-arid region of Tunisia is compared by means of compositional perturbation vectors and biplots. This set of underused
mathematical tools belongs to a family of statistics created specifically to deal with compositional data. The two sampling devices operate at a
flow rate in the range of 1 m3 h−1, with a cut-off diameter of 10 µm. The first device is a low-cost
laboratory-made system, where the largest particles are removed by gravitational settling in a vertical tube. This new system will be compared to
the second device, a brand-new standard commercial PM10 sampling head, where size segregation is achieved by particle impaction on a metal
surface. A total of 44 elements (including rare earth elements, REEs, together with Al, As, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na,
Ni, P, Pb, Rb, S, Sc, Se, Sr, Ti, Tl, U, V, Zn, and Zr) were analysed in 16 paired samples, collected during a 2-week field campaign in
Tunisian dry lands, close to source areas, with high levels of large particles. The contrasting meteorological conditions encountered during the
field campaign allowed a broad range of aerosol compositions to be collected, with very different aerosol mass concentrations. The compositional data analysis (CoDA) tools show
that no compositional differences were observed between samples collected simultaneously by the two devices. The mass concentration of the particles
collected was estimated through chemical analysis. Results for the two sampling devices were very similar to those obtained from an online aerosol
weighing system, TEOM (tapered element oscillating microbalance), installed next to them. These results suggest that the commercial PM10
impactor head can therefore be replaced by the decanter, without any measurable bias, for the determination of chemical composition and for further
assessment of PM10 concentrations in source regions.
