Abstract

Sebagai upaya untuk meningkatkan kualitas dan kompetensi peserta didik maka diperlukan suatu perencanaan agar pelaksanaan pembelajaran berjalan optimal. Salah satu wujud dari kompetensi guru dalam perencanaan, yaitu guru mampu membuat bahan ajar yang dapat memotivasi peserta didik dalam pemecahan suatu masalah. Perencanaan tersebut dapat tertuang pada lembar kerja peserta didik (LKPD) berbasis masalah (PBL). Berdasarkan hasil data pendahuluan terhadap kegiatan pembelajaran yang dilakukan oleh guru–guru IPA Kota Pagaralam, didapatkan hasil bahwa 78% guru–guru biologi IPA menggunakan metode ceramah melalui media conference seperti zoom meeting. Penggunaan model pembelajaran berbasis masalah jarang dilakukan mengingat saat ini masih berada di kondisi pandemi covid-19. Selain itu sebagian besar guru–guru IPA kota Pagaralam menggunakan LKPD yang terdapat di buku saja. Hal ini kurang sesuai dengan kondisi nyata yang ada lingkungan peserta didik sehingga peserta didik kurang memiliki kemampuan dalam pemecahan masalah. Oleh karena itu, upaya yang harus dilakukan, yaitu melakukan perencanaan dengan mendesain LKPD berbasis PBL yang dirancang secara digital menjadi E-LKPD Berbasis PBL. Tujuan pelatihan ini: (1) guru dapat mengurutkan langkah–langkah pembelajaran PBL (Problem Based Learning); (2) guru dapat merancang E-LKPD berbasis pembelajaran PBL; (3) guru dapat menghasilkan E-LKPD berbasis pembelajaran PBL. Model kegiatan yang akan dilaksanakan yaitu model pendampingan yang ditujukan kepada guru IPA MGMP kota Pagaralam, berjumlah 20 orang yang berasal dari beberapa SMP Negeri dan Swasta di kota Pagaralam.  Berdasarkan hasil Evaluasi PreTest dan Posttest menunjukkan peningkatan pemahaman guru dalam pembuatan E-LKPD berbasis PBL setelah mengikuti pelatihan. Peningkatan pemahaman terlihat melalui peningkatan nilai rata–rata hasil tes awal dan tes akhir sebesar 47,44%. Berkaitan dengan hal tersebut, setelah kegiatan pelatihan ini diharapkan adanya kegiatan lanjutan berupa integrasi E-LKPD dalam rancangan pelaksanaan pembelajaran (RPP)

Abstract

This study aims to develop indigenous knowledge-based teaching materials on water cycle topics under basic competencies 3.10 and 4.10 in junior high schools. The method used in this research is the type II developmental research of Richey & Klein consisting of the exploration and evaluation stages (trial). This research was conducted in two cycles of evaluation. The results of the development of teaching materials were tested for validity by 5 validators, readability was tested to sixteen students using the gap test. Based on the research results, the validation value for the development of the teaching materials was 4.36 which falls into the very valid category. The readability test results were 91.17% and when converted using Bormuth criteria, it means that the product is easy to understand. In conclusion, this teaching material applies to junior high school students, particularly the water cycle topic.

Abstract

This study was conducted to analyze the effect of post-production storage time on antioxidant activity in soy milk. Antioxidants are compounds that can ward off free radicals, so it is important to know their stability over time. The storage time used in this study was 1, 4, 7, 10, and 13 hours post-production. Antioxidant activity testing was carried out using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. Qualitatively, the color change of the DPPH solution was observed from purple to light yellow, while quantitatively the absorbance value was measured using UV-Vis Spectrophotometry. The inhibition value and IC50 were calculated to determine the strength of antioxidant activity in soy milk. The results showed that soy milk with a storage time of 1 hour had the best antioxidant activity with an IC50 value of 28.19 μg/ml which was classified as very strong. At 4 hours of storage time, the IC50 value of 37.28 μg/ml is classified as moderate, while at 7 hours and 10 hours the IC50 values ​​were 146.95 μg/ml and 119.38 μg/ml, respectively, which are also classified as moderate. At 13 hours, the antioxidant activity decreased drastically with an IC50 value of 228.90 μg/ml, which is classified as very weak. The antioxidant activity of soy milk decreased with increasing storage time. Factors such as temperature, light, and components of soy milk contribute to the degradation of antioxidant activity. Therefore, consumption of soy milk should be done within a shorter time after production to obtain optimal antioxidant benefits.
