Abstract

Program Pengabdian kepada Masyarakat (PKM) ini bertujuan untuk memberikan keterampilan praktis sekaligus meningkatkan pemahaman mengenai konservasi energi bagi penghuni Panti Asuhan Nursiamatu di Kota Makassar. Konsumsi listrik yang tinggi pada malam hari seringkali menjadi beban operasional bagi lembaga sosial. Metode yang digunakan dalam kegiatan ini adalah lokakarya partisipatif, yang terdiri dari pemaparan teori dasar fisika pembakaran dan praktik langsung pembuatan lilin dengan bahan yang mudah didapat. Peserta dilatih untuk memformulasi lilin yang tahan lama sebagai sumber penerangan alternatif saat pemadaman listrik atau penggunaan terbatas di malam hari. Hasil kegiatan menunjukkan peningkatan signifikan pada keterampilan peserta (85%) dan kesadaran yang lebih baik terhadap efisiensi energi. Inisiatif ini tidak hanya menawarkan solusi teknis untuk penerangan, tetapi juga menumbuhkan semangat kewirausahaan dan kemandirian bagi anak-anak panti asuhan.

Abstract

Clean water treatment technology continues to develop in response to increasing water pollution problems caused by turbidity, organic pollutants, microorganisms, and dissolved contaminants. One of the most widely applied treatment methods is filtration using various media such as silica sand, activated carbon, zeolite, and biosand filters. This study aims to analyze the effectiveness of several filtration media in improving water quality based on previous research findings. The method used was a literature review with a descriptive analysis approach, examining ten scientific articles from national and international journals published between 2018 and 2025. The results indicate that silica sand is effective in reducing turbidity and suspended particles, activated carbon demonstrates strong adsorption capability for odor, color, and organic compounds, while zeolite effectively reduces heavy metals and ammonia through ion exchange mechanisms. Biosand filters show good performance in reducing microorganisms in household-scale water treatment. Furthermore, combinations of filtration media provide higher effectiveness than single media by simultaneously optimizing physical, chemical, and biological filtration processes. Therefore, selecting appropriate filtration media combinations is important to improve clean water treatment efficiency.
