Abstract

ZnO/NiFe2O4 nanoparticles were synthesized by chemical co-precipitation method and were calcied at 500 0C for 5 h. The Composites synthesis within ratios of zinc oxide to nickel ferrite of 1:0,1, 2:0,1 and 3:0,1. The adsorption and photocatalytic activity of The removal of ZnO/NiFe2O4 were systematically investigated using Rhodamine B and waste water pulp and paper indsutry solution as a model contaminant. Rhodamine B (10 mg/L) and waste water pulp and paper indsutry solution by ZnO/NiFe2O4 (2:0.1) after 2 h reached 98,71% under LED lamp and 91,85% under solar light irradiation for Rh, and after 3 h reached 28,03% under LED lamp for lignin . •OH and h+ play important roles in the decolorization of RhB solution by NiFe2O4/ZnO under simulated LED lamp and solar light irradiation. The adsorption kinetics pattern under conditions of LED lamp and sunlight follows first order kinetic adsorptions.

Abstract

Henti jantung sering kali terjadi secara mendadak tanpa tanda-tanda sebelumnya. Kondisi ini, apabila tidak segera ditangani dengan tepat, dapat berujung pada dampak buruk hingga kematian. Menganalisis Tingkat Pengetahuan Pegawai UP3 PLN Banjarmasin tentang Bantuan Hidup Dasar. Penelitian ini menggunakan desain penelitian deskritif kuantitatif. Populasi dalam penelitian ini adalah pegawai UP3 PLN Banjarmasin dengan jumlah sampel 40 orang. Analisis statistik menggunakan analisis deskritif. Tingkat pengetahuan responden tentang BHD hampir seluruhnya 90% berada pada kategori cukup dengan jumlah 36 orang. Setiap orang perlu memberikan pertolongan pertama pada saat keadaan gawat darurat.
