| dc.description.abstract | Biokonversi limbah pangan larva BSF berpotensi mengurangi timbulan sampah, namun sering terkendala akibat emisi bau. Penelitian ini bertujuan mengevaluasi arang tempurung kelapa sebagai media biofilter reduksi kebauan. Media diinokulasi dengan kompos selama 3 minggu, menghasilkan pertumbuhan mikroorganisme bakteri 1,4 × 10^7 CFU/g dan Bacillus sp. 2,8 × 10^6 CFU/g. Selama pengujian, suhu dan kelembapan relatif berada pada 28–31 °C dan 83-95%, mendukung kinerja biofilter. Biofiltrasi mampu mereduksi H2S hingga 100% dari konsentrasi tertinggi 8 ppm menjadi 0 ppm, sedangkan NH3 tetap bernilai < 0,1 ppm baik sebelum maupun setelah biofiltrasi. Skala hedonisme limbah biokonversi BSF berkisar antara -1,8 hingga -2,5, lebih tinggi dibandingkan limbah tanpa perlakuan pada rentang -2,1 hingga -3,8. Efisiensi reduksi mencapai 100% setelah proses biofiltrasi, dengan nilai standar deviasi mendekati nol menunjukkan kesepakatan panelis terhadap hilangnya kebauan. Peningkatan konsentrasi H2S berkorelasi cukup kuat dengan penurunan skala hedonisme, dengan R^2 bernilai 0,72 (tanpa perlakuan) dan 0,80 (biokonversi BSF). Biofilter berbasis arang tempurung kelapa efektif dalam mereduksi kebauan selama tujuh hari pengujian. | - |
| dc.description.sponsorship | Bioconversion of food waste with BSF has the potential to reduce waste generation, but is often constrained by odor emissions. This study evaluates coconut shell charcoal as a biofilter medium for odor reduction. The media was inoculated with compost for 3 weeks, resulting in the growth of bacterial microorganisms of 1.4 × 10^7 CFU/g and Bacillus sp. 0.8 × 10^6 CFU/g. During testing, the temperature and relative humidity were 28–31 °C and 83–95%, supporting the performance of the biofilter. Biofiltration was able to reduce H2S by 100% from a maximum concentration of 8 ppm to 0 ppm, while NH3 remained at <0.1 ppm both before and after biofiltration. The hedonic scale of BSF bioconversion waste ranged from -1.8 to -2.5, higher than untreated waste in the range of -2.1 to -3.8. Reduction efficiency reached 100% after the biofiltration process, with a standard deviation value close to zero indicating the panelists agreement on the elimination of odor. The increase in H2S concentration correlated strongly with a decrease in the hedonic scale, with R^2 of 0.72 (untreated) and 0.80 (BSF bioconversion). The coconut shell charcoal based biofilter was effective in reducing odor during the seven days test. | - |
