Abstract

Waste cooking oil is one of household waste. Waste cooking oil is usually disposed to the sewers or gardens. Utilization of waste cooking oil is by recycling it into a solid soap product. The production of solid soap from waste cooking oil is a solution to reduce waste. There are various formulas for making soap products from waste cooking oil. In order to utilize waste cooking oil becomes maximal dan useful, it is necessary to select the best formula for further development. The research begins by identifying the soap formula with a simple process. The identification results obtained six soap formulas that can be produced on a household scale. The six soap formulas were then produced and tested according to Indonesia’s national standards (SNI). The method used to select the best formula was Analytical Hierarchy Process (AHP), which involved four partisipants as experts. The result of the decision of the best soap formula is Soap 6. Meanwhile, the three priority attributes for decision-making are soap standard (SNI), cleaning power, and the ability to hold bacteria.

Abstract

Batteries are the primary component in electric motorcycle propulsion systems, playing a crucial role in storing and supplying energy. However, batteries have a limited lifespan, potentially becoming waste after their useful life. Battery waste is categorized as hazardous and toxic waste (B3) because it contains heavy metals and chemical compounds that can negatively impact human health and the environment if not managed properly. As the adoption of electric motorcycles increases in Indonesia, particularly in the Special Region of Yogyakarta (DIY), the issue of battery waste management is becoming increasingly important. Currently, there are no electric motorcycle manufacturers openly willing to manage post-life battery waste, particularly through recycling activities. This situation creates a gap that informal actors could potentially exploit. Informal actors often possess flexibility and basic technical skills, but their capacity to manage battery waste safely and sustainably still needs to be mapped and strengthened. This study focused on mapping the potential capabilities of informal actors in the Special Region of Yogyakarta by 2025. The results indicate that the potential for informal actors capable of providing battery repair services is only around 1%. This figure is very small and therefore insufficient to support future battery waste management needs. Therefore, multi-stakeholder support is needed, from the government and manufacturers to the community, to encourage capacity building among informal actors. This effort is crucial to anticipate the success of the government's 2030 target for electric vehicle conversion, while also ensuring environmental sustainability.
