<p>Tujuan penelitian ini untuk mengetahui penggunaan Media Pembelajaran Corong Hitung berpengaruh terhadap hasil belajar siswa. Jenis penelitian ini adalah eksperimen, Populasi dalam penelitian ini adalah seluruh siswa kelas II SDN Jatiroto 01 Kayen. Sampel dalam penelitian ini adalah kelas II yang berjumlah 20 siswa dengan menggunakan sampel jenuh. Desain penelitian eksperimen menggunakan <em>Pre Experimental Design</em> yang digunakan adalah <em>One Group</em> <em>Pretest-Posttest Design</em>. Berdasarkan hasil analisis data normalitas tahap awal <em>pretest </em>diperoleh L<sub>0 </sub>= 0,129 < L<sub>tabel </sub>= 0,190 maka H<sub>0</sub> diterima dan data berasal dari distribusi normal. Begitupula dengan hasil analisis data normalitas tahap akhir <em>posttest </em>diperoleh L<sub>0 </sub>= 0,140 < L<sub>tabel </sub>= 0,190 maka H<sub>0</sub> diterima dan data berasal dari distribusi normal. Selanjutnya perhitungan uji t terhadap hasil belajar diperoleh t <sub>hitung </sub> = 9,372 > t <sub>tabel </sub>= 1,729. Maka H<sub>i</sub> diterima. Hal ini berarti hasil belajar Matematika Siswa kelas II SDN Jatiroto 01 Kayen mencapai KKM 65 dan hasil perhitungan ketuntasan belajar siswa di kelas mencapai 85 %. Media Pembelajaran Corong Hitung berpengaruh terhadap hasil belajar Matematika materi Perkalian siswa kelas II SDN Jatiroto 01.</p><p> </p><p>Kata kunci : media pembelajaran corong hitung, hasil belajar matmatika</p>
Septic Tank is a shelter for solid materials of human waste (faeces) which will quickly fill up when there is no decomposition process by bacteria decomposers. The amount of bacterial decomposers in a septic tank is generally less compared to the accumulation rate, so it is necessary to supply bacteria decomposers. The addition of these microorganisms is very cheap when compared to the cost of desludging or drying beside being practical, healthy and environmentally friendly. The decomposing bacteria (microorganisms) will decompose the solid materials in the septic tank into water (H2O) and some gas (CO2).Microorganisms that can decompose or degrade human faeces are PAOs (polyphosphate accumulating organisms) by degrading the polyphosphate into phosphate. Microorganisms that play a role in the decrease of phosphates are bacteria and fungi. Aerobic bacteria such as Pseudomonas sp. is one of the phosphate-degrading microorganisms. This research used the Pour Plate and gram staining method for microscopic observation to find the morphology of Pseudomonas sp.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
