Abstract

The objective of this study is to determine the outcomes of the requirements analysis and learning materials for electrolyte and non-electrolyte solution materials. Additionally, learning materials will be developed utilising computational chemical calculations and visualisation of the results to create learning media based on the National Education Standards Agency (BSNP) requirements. This kind of study uses the ADDIE development model and is referred to as development research. There are five steps in the current ADDIE model: analysis, design, development, implementation, and evaluation. The entire student body of one of the senior high schools in Padangsidempuan City, North Sumatera, Indonesia, served as the study's population. The participants in this research were senior high school students from Padangsidempuan City, North Sumatera, Indonesia. The use of a purposive sampling technique yields grade X as the research sample. An inquiry form derived from the National Education Standards Agency was used as the research tool. Utilising a significance level of 5%, the data analysis was conducted using the SPSS 22 for Windows software. The investigation's findings demonstrate the need for educational materials to help pupils struggling with learning. Based on 95% validation findings, the learning materials for both electrolyte and non-electrolyte solutions visualise the outcomes of computational chemical calculations.

Abstract

Ulat sagu memiliki nama yang beragam dan paling sering ditemui di daerah Kalimantan, Sulawesi, Papua dan Sumatera yang diperoleh dari batang pohon sagu yang telah tumbang dan sudah membusuk. Tujuan penelitian untuk mengetahui protein ulat sagu dengan metode Kjedhal, Spektro fotometer dan SDS-PAGE. Jenis penelitian dengan melakukan kajian literature dari buku, artikel dan jurnal sepuluh tahun terakhir dari google scholer. Hasil analisis menggunakan metode Kjedhal pada batang berduri sebesar 11,8652% yang tidak berduri sebesar 10,06988%. Penelitian lainnya yang dilakukan di hal mehera maluku utara kadar protein total sebesar 4,0575%. Hasil analisis menggunakan metode spektro fotometri dan SDS dengan pengeringan garam dan tanpa garam menunjukkan ulat sagu control memiliki protein yang lebih besar (4,93 µg/µl) daripada yang diberi perlakukan dan penggaraman konsentrasi 10% (b/b) selama 1 jam tanpa panas pita-pita protein tidak terjadi penurunan atau penipisan secara signifikan. Analisis Pengasapan dengan garam dan tanpa garam menunjukan ulat sagu control lebihbesar (4,93 µg/µl) dibandingkan dengan yang diberi perlakuan dan semakin lama waktu pengasapan maka semakin banyak pita protein yang terdenaturasi dengan berat molekul yang semakin kecil. Pengaruh penggaraman konsentrasi 10 % b/b dan pengasapan terhadap jumlah profil protein ulat sagu cenderung lebih besar dibandingkan pegaruh pengasapan saja.
