Abstract

Extract of Snake Plant (Sansevieria sp.) As a Reducer of Indoor Air Pollution, Volatile Organic Compounds (VOC) -Benzene. The quality of the indoor environment has become a health concern, as city dwellers spend 80-90% of their time indoors, where outdoor air pollution is several times higher. Indoor potted plants can remove airborne contaminants such as volatile organic compounds (VOCs), more than 300 of which have been identified in indoor air. and a very wide range of light, and is resistant to pollutants. This plant is also able to absorb more than 107 harmful pollutants in the air, this is due to Sansevieria sp. contains the active ingredient Pregnane glycosides. These active ingredients function to reduce pollutants into organic acids, sugars and amino acids so that these pollutants are no longer harmful to humans3. This study aims to see the extract of the tongue-in-law in reducing Volatile Organic Compounds (VOCs) in the room. The method used in this research is true experimental design with pre and post-test design without control design. Based on the results of the study, the decrease in benzene levels was done by using the sansevieria extract concentration with the average reduction proportions, namely: 10 ppm concentration; 98.24%, 20 ppm; 98.47%; 30 ppm; 98.73%. The results of statistical tests using the Mann Whitney U test showed that the results were 0.000 <0.05 so that there was a relationship, namely that there was a difference in the concentration of the extract of Sansevieria sp. against decreased levels of benzene. The most effective level of Sansevieria extract in reducing benzene levels in the air was 30 ppm with an average reduction proportion of 98.73%.

Abstract

Lingkungan tempat kerja terdapat banyak bahaya dan risiko terhadap kesehatan pekerja itu sendiri, paparan kebisingan akan berdamapak keselamatan dan kesehatan seperti kebisingan yang berasal dari compressorKebisingan yang tinggi depatdilakukanpengendalian dengan merekayasa lingkungan atau mendesain pengendalian dari sumber suara dengan penambahan lapisan yang dapat untuk mereduksi kebisingan. Tujuan penelitian ini adalah untuk mengetahui perbedaan berbagai variasi ketebalan serbuk kayu dan papan telur sebagai media peredam kebisingan. Penelitian ini menggunakan true experimental design dengan pre-post test only design dan data dianalisis menggunakan uji Kruskal-Wallis. Untuk menentukan perbedaan serbuk gergaji dan papan telur sebagai pereduksikebisingan. Hasil penelitian menunjukkan nilai intensitas kebisingan sebelum dilakukan perlakuan berada pada rerata 101 dB(A). Nilai intensitas kebisingan ketebalan 1 cm rata-rata persentase penurunan sebesar 38,89%. Ketebalan 2 cm rata-rata persentase penurunan sebesar 39,48% dan Pada ketebalan 3 cm rata-rata persentase penurunan sebesar 38,48%. Kesimpulan penelitian ini terdapat perbedaan yang signifikan antara pengunaan serbuk gergaji dan papan telur dengan ketebalan 1 cm, 2 cm dan 3 cm terhadap penurunan kebisingan pada mesin compressor. Perlu dilakukan penelitian lanjutan terkait ketebalan noise barrier yang efektif.
