Abstract

Sandblasting waste from the shipbuilding industry and fly ash waste from industry and electric steam power plants in Indonesia are relatively high in quantity, are B3, and can potentially cause serious environmental pollution. This research aims to utilize this waste as material for ferrocement concrete, where the SiO2 and Al2O3 content from fly ash replaces some of the cement, silica sand from sandblasting waste replaces sand, and additional wire mesh as reinforcement. The method used is a quantitative experiment, where the material to be used is tested for gradation and TCLP. The finished ferrocement concrete is tested for flexural strength. The test results show that the raw material meets the gradation standards in SNI 03 2834 2000, as well the TCLP test results which show that the B3 heavy metal content is Barium, Zinc, and Copper in the sandblasting waste value is below the quality standards of PP No. 22 of 2021 Appendix XI so that all materials can be used for mix designs. The mix design created has a composition ratio of 1S:1.5PB, 1S:1.5PB:50AT, 1S:2PB, and 1S:1PB:50AT. The 1S:2PB ratio composition has the highest average flexural strength, namely 17.46 MPa, which is suitable for light vertical load construction work

Abstract

Pelatihan digital marketing pada dua puluh lima ibu rumah tangga anggota paguyuban Pos Pendidikan Anak Usia Dini (PAUD) Terpadu (PPT) Tunas Mulia Keputih Surabaya perlu dievaluasi untuk melihat tingkat pemahaman peserta setelah diberikan pelatihan. Tujuan penelitian ini untuk melihat perubahan tingkat pemahaman peserta terhadap materi pelatihan setelah diberikan pelatihan serta melihat perbedaan rerata dari nilai pre-test dan post-test. Peserta diberikan pre-test dan post-test sebagai langkah awal untuk melihat efektivitas pelatihan. Nilai pre-test dan post-test diuji dengan wilcoxon signed rank test untuk melihat perbedaan rerata setelah sebelumnya dilakukan uji normalitas. Berdasarkan uji normalitas dengan shapiro wilk, diperoleh nilai p-value kurang dari 0.05 sehingga disimpulkan nilai pre-test dan post-test tidak berdistribusi normal. Nilai rata-rata post-test mengalami kenaikan sebesar 5.11% dari nilai rata-rata pre-test yang mengindikasikan ada peningkatan pemahaman peserta setelah diberikan pelatihan. Berdasarkan uji wilcoxon signed rank test memberikan hasil bahwa nilai p-value lebih dari 0.05 sehingga disimpulkan tidak terdapat perbedaan signifikan terhadap nilai rerata peserta baik sebelum dan setelah diberikan pelatihan.
