Implementation of Problem-Based Learning: What is the Influence on Students' Reasoning Ability in Elementary Schools?

This study aimed to determine the effect of applying the PBL learning model on the reasoning abilities of fourth-grade elementary school students Muhammadiyah 1 Krian. Types of experimental research and using one group pre-test-post-test design method. The population in this study were 23 fifth-grade students at SD Muhammadiyah 1 Krian. The researcher used a saturated sampling technique because population sizes were small. Reasoning ability data was obtained from essay tests before and after the application of PBL. Then the study results were analyzed using descriptive statistical techniques and the N-Gain test using the SPSS version 26 software. The results of this analysis indicate the reasoning ability of the pre-test post-test results showed a significant difference between the average value of the pre-test (63.26) and post-test (82.74), and. those using the N-Gain test obtained an average of 0.52 which indicates the moderate category, so using this PBL learning model can affect the reasoning abilities of elementary school students

The purpose of this study was to determine the effect of applying the PBL learning model on the reasoning abilities of fourth grade students at SD Muhammadiyah 1 Krian. This type of experimental research and using the one group pretest-posttest design method. Data on reasoning ability (reasoning) was obtained from essay tests before and after implementing PBL. The results of this analysis show that the reasoning ability of the pretest posttest results is significant between the average pretest (63.26) and posttest (82.74) and those using the N-Gain test are obtained with an average of 0.52 which indicates the moderate category, then using this PBL learning model can influence reasoning abilities elementary school students

Potensi Limbah Kulit Nanas (Ananas comsus) dan Kemangi (Ocimum basilicum) sebagai Bahan Dasar Hand sanitizer

Kulit nanas dan daun kemangi memiliki potensi untuk dijadikan hand sanitizer di Era Pandemi covid-19 saat ini mengandung senyawa flavonoid yang bersifat desinfektan yang mampu menghambat pertumbuhan bakteri. Bentuk sediaan yang dibuat adalah hand sanitizer spray. Tujuan penelitian ini yaitu untuk mengetahui tahapan pembuatan hand sanitizer berbahan dasar ekstrak limbah kulit nanas dan daun kemangi serta mengetahui hasil uji pH, uji iritasi kulit, uji bakteri, dan uji homogenitas. Pada produk hand sanitizer ekstrak limbah kulit nanas dan daun kemangi diperoleh dengan metode penyaringan biasa dan penambahan etanol 96% untuk menetralisasikan pH hand sanitizer agar aman untuk kulit serta penambahan ocean fresh fragfrance untuk mengurangi bau dari ekstrak kulit nanas. Hand sanitizer ini diformulasikan dengan konsentrasi limbah kulit nanas : daun kemangi : etanol (1:1:3, 1:2:5, 1:3:6). Berdasarkan hasil penelitian didapatkan bahwa sampel pH berada pada range 4,5-4,76 yang masih aman untuk kulit sesuai SNI. Campuran tersebut setiap sampel yaitu homogen dan tidak menyebabkan iritasi kulit. Efektivitas yang paling baik dalam menghambat pertumbuhan bakteri yaitu konsentrasi 1:3:6 dengan 86,4%. Ekstrak limbah kulit nanas dan daun kemangi dapat dijadikan produk yang ramah lingkungan serta ekonomis
