Abstract

To remain competitive, the soap manufacturing industry must understand consumer preferences. This study uses the Kansei Engineering method to explore consumer desires for bar soap, which links user impressions and emotions (Kansei) to product design elements. Thirteen Kansei words were identified and translated into five design items, each with multiple categories. Using orthogonal design in SPSS 24.0, 16 stimuli were generated. Conjoint analysis was then applied to examine the relationship between Kansei words and product attributes. Results revealed the most preferred combination: round shape, white colour, medium size (85g), moisturizing function, and long-lasting fragrance. These findings guide designing bar soap products that better match consumer expectations.

Abstract

This Community Service activity addresses sheep manure waste issues at Umroh Farm, Patumbak Village, Deli Serdang. Waste buildup causes odor and environmental pollution despite its potential as biogas material. The solution was implementing appropriate technology by constructing a household-scale biogas reactor. Activities included participatory training, equipment assembly, and field trials. The digester, with a ±200-liter capacity, was made from plastic drums and equipped with input-output, cleaning, and gas collection lines. The implementation produced an average of 0.015 m³ of biogas per hour, with fire ignition lasting 1–2 seconds. The program reduced livestock waste, improved farmers’ awareness and skills and supported clean energy and climate change mitigation goals. Its success shows that simple biogas technology can provide an integrated solution for environmental management and community empowerment.
