Abstract

Hand soap is one of the means to clean hands from dirt, germs and other things that make hands dirty. To kill bacteria, some hand soaps contain active substances that can have a negative effect on humans who have sensitive skin, which can cause irritation. Some synthetic active ingredients that are harmful to human skin health are diethanolamine (DEA), Sodium Lauryl Sulfate (SLS), and triclosan which functions as an antibacterial. This study aims to obtain the composition of basil leaf extract with the right maceration time as an antibacterial and can produce liquid hand soap products that are in accordance with the quality of SNI 2588:2017 by varying the composition of the basil leaf extract and varying the maceration time. Variations in the composition of basil leaf extract are 3%, 6%, and 9% as well as variations in maceration time of 3 days and 7 days. Analysis of liquid hand soap products includes pH, insoluble in ethanol, free fatty acid content, surface tension, organoleptics, and bacteria. Based on the results of the analysis, all samples met the quality of SNI, but the sample with the best formulation of liquid hand soap was obtained at a composition of 9% extract (9 ml of basil leaf extract in 100 ml of soap volume) with a maceration time of 7 days. The results of the analysis showed that the resulting pH value is 8, the material is insoluble in ethanol 0.46%, free fatty acids 0.32% and the surface tension of soap is 13.52 dyne/cm.

Abstract

Various types of bacteria, viruses and fungi will be easier to stick to and thrive on unclean hands. Making people use products that contain antiseptics such as soap and hand sanitizer. However, in general, the basic ingredient for making antiseptics comes from alcohol. The development of antiseptic products can be done with natural ingredients such as using sweet orange peel (Citrus sinensis (L.)). It is known that sweet orange peel (Citrus sinensis (L.)) contains saponin, flavonoid, and tannin compounds which act as antibacterial so that it can be a natural antiseptic ingredient for making hand sanitizer gel. This study aims to determine the effect of maceration time and composition of sweet orange peel extract on antiseptic power in hand sanitizer gel preparations and can produce hand sanitizer products that are in accordance with SNI quality by varying the maceration time of the extract, namely 3 days, 5 days and 7 days the amount of sweet orange peel extract 5%, 10% and 15%. The product analysis of hand sanitizer gel includes organoleptic, homogeneity, pH, density, viscosity, dispersibility and bacteria. Based on the results of the analysis, all samples met the quality of SNI, but the best sample was 15% composition with a maceration time of 7 days. The results of the analysis showed that the pH value was 6, the density was 1.0470 gr/cm3, the viscosity was 578.08 cP, the dispersion was 8.3 cm.

Abstract

Used cooking oil (UCO) from institutional kitchens poses environmental and health risks if improperly disposed of. This community programme, jointly organised by Politeknik Negeri Sriwijaya and Politeknik Malaysia Merlimau, aimed to introduce a simple method for converting UCO into solid soap, an eco-friendly and economically valuable product. The activity employed an applied mixed-methods design, comprising pre-assessment, technical training, hands-on practice, and post-evaluation. Participants learned about UCO purification, saponification, and safe handling of NaOH. Results indicate a substantial increase in participants’ knowledge and awareness, with 100% of respondents demonstrating improved understanding of UCO hazards and soap-making procedures. Practical implementation was successful, yielding approximately 150 bars of solid soap during the workshop. All participants expressed willingness to continue soap production independently due to its low cost, environmental benefits, and potential for micro-enterprise. The programme demonstrates that simple, community-based technical interventions can effectively enhance practical competence and promote sustainable waste valorisation. This model shows strong potential for replication in similar educational and community settings.

Abstract

Limbah cair Printed Circuit Board (PCB) mengandung ion logam berat Fe yang berpotensi mencemari lingkungan sehingga memerlukan metode pengolahan yang efektif. Penelitian ini bertujuan mengidentifikasi gugus fungsi dan morfologi komposit silika–kitosan berbasis abu ampas tebu, menganalisis pengaruh variasi massa adsorben dan waktu kontak terhadap efisiensi serta kapasitas adsorpsi ion Fe, serta menentukan model isoterm adsorpsi yang paling sesuai. Silika hasil sintesis dimodifikasi dengan kitosan untuk meningkatkan jumlah situs aktif adsorben. Karakterisasi FTIR menunjukkan keberadaan gugus –OH (3384,4 cm⁻¹), –NH₂ (1640 cm⁻¹), serta Si–O–Si dan Si–O (1051,1; 790,2; dan 708,2 cm⁻¹) yang mengonfirmasi terbentuknya komposit silika–kitosan. Analisis SEM menunjukkan permukaan menjadi lebih kasar dan granular setelah modifikasi. Pengujian adsorpsi dilakukan menggunakan variasi massa adsorben 0,1; 0,2; dan 0,3 g serta waktu kontak 40–120 menit dengan analisis AAS. Hasil menunjukkan kapasitas adsorpsi menurun seiring peningkatan massa adsorben. Kapasitas adsorpsi tertinggi sebesar 16,2 mg/g diperoleh pada massa 0,1 g selama 120 menit, sedangkan efisiensi tertinggi sebesar 82,5% diperoleh pada massa 0,2 g selama 60 menit. Model Langmuir memberikan nilai R² lebih tinggi (0,9924–0,9995), menunjukkan adsorpsi berlangsung secara monolayer pada permukaan homogen. Komposit silika–kitosan berpotensi sebagai adsorben ramah lingkungan untuk pengolahan limbah cair PCB.
