Abstract

The use of sodium compounds are sodium carbonate, sodium silicate, sodium chloride andsodium hydroxide as auxiliary agent in the malam releasing process in batik was investigated. Thisstudy aims to determine the effectiveness of these sodium compounds for the malam releasingprocess and know the factors that influence the effectiveness of the auxiliary in the process. Thisstudy used an experimental method with 5 treatments and 3 repetition that treatment A (withoutauxiliray agent), B (sodium carbonate), C (sodium silicate), D (sodium chloride), and E (sodiumhydroxide). The level of effectiveness is measured by the percentage of the malam release of thecotton fabric. The testing process is done by successively making designs on cotton fabric, then themalam sticking process, the coloring process, and the malam releasing process. The malam releasingprocess do with each using auxiliary agent sodium carbonate, sodium silicate, sodium chloride,sodium hydroxide and one sample without auxiliary substances are used as controls. The resultsshowed that the use of auxiliary from sodium compounds can simplify the malam releasing process.Sodium compounds that most effective to be used in the malam releasing process was sodiumsilicate followed by sodium carbonate, sodium chloride, and sodium hydroxide. The most effectivein the malam releasing process in batik cotton fabric was sodium silicate. This was because theamount of sodium unsure in the sodium silicate compounds most numerous and the bonding ofsodium and silicate was weakest among other sodium compounds used in this study.

Abstract

Penelitian ini bertujuan untuk menganalisis dan mensintesis berbagai temuan penelitian terkait pengembangan media pembelajaran interaktif berbasis Problem-Based Learning (PBL) dalam meningkatkan kemampuan berpikir kritis dan hasil belajar IPA siswa sekolah dasar. Dengan menggunakan metode Systematic Literature Review (SLR) berbasis protokol PRISMA dan kerangka PICOC, diperoleh 15 artikel jurnal relevan yang diterbitkan antara tahun 2020–2025. Hasil kajian menunjukkan bahwa integrasi PBL dengan media interaktif seperti e-modul, LKPD digital, multimedia, dan e-book interaktif secara konsisten mampu meningkatkan kemampuan berpikir kritis, motivasi, serta pemahaman konsep sains siswa. Penerapan pembelajaran interaktif berbasis PBL juga mendorong terciptanya pembelajaran yang aktif, kolaboratif, dan bermakna sesuai tuntutan kompetensi abad ke-21. Sebagian besar penelitian yang dianalisis menggunakan metode Research and Development (R&D) dan eksperimen, serta menunjukkan validitas dan efektivitas media yang tinggi. Simpulan dari penelitian ini menunjukkan bahwa media pembelajaran interaktif berbasis PBL merupakan strategi inovatif dan efektif untuk meningkatkan kualitas pembelajaran IPA di sekolah dasar. Penelitian selanjutnya disarankan untuk mengkaji efektivitas jangka panjang dan integrasi teknologi digital melalui model hibrida seperti STEM-PBL atau gamifikasi guna memperkuat keberlanjutan pengembangan kemampuan berpikir kritis dan hasil belajar siswa
