Aromatherapy is beneficial for maintaining and enhancing physical, physiological, and spiritual well-being by consuming flowers, roots, fruits, resins, bark, and other aromatic compounds from plants. In Indonesia, around 90% of the used cooking oil produced is not managed properly, leading to environmental issues and contaminating soil and water, as well as public health. To reduce its negative impact on the environment and public health, it can be processed into valuable products such as aromatherapy candles. The purpose of this study is to study the impact of using used cooking oils and its benefits for the community of Sinarsari Village so that they can utilize this waste more sustainably and efficiently. The Tim PPK Ormawa HImasiter IPB (Student Association of Nutrition and Animal Feed) plays a significant role in promoting new innovations that benefit the community, one of which is the creation of aromatic candles with the aim of learning how to recycle used oil into useful products. The results of this comprehensive evaluation will assist the implementing team in identifying the strengths, weaknesses, opportunities, and challenges of this program.

The increase in population has an impact on increasing waste, including cooking oil waste known as used cooking oil. This used cooking oil is not always thrown away, but can also be reused. However, improper disposal of waste cooking oil can cause environmental problems. Used cooking oil is a type of waste that can pollute the environment by increasing COD (Chemical Oxygen Demand) and BOD (Biological Oxygen Demand) levels in the water. Apart from that, this oil can also cause an unpleasant odor due to the biological degradation process. Currently, used cooking oil is often thrown directly into the drain. This research was conducted in Wonorejo Village, Surabaya, with data collection methods in the form of questionnaires, field observations and interviews as primary data, as well as a general description of the area and related literature as secondary data. The results of the analysis show that there are variations in views and practices in managing used cooking oil among respondents. The level of public awareness about the importance of managing used cooking oil to support the zero waste concept varies. The majority of respondents (64%) stated that the main responsibility for managing used cooking oil lies with the users themselves.

The people of Pecekelan Village, Sepuran District, Wonosobo Regency, Central Java, face a unique challenge in the form of an unpleasant odor from cattle pens adjacent to settlements, reflecting a strong agrarian life but interfering with daily comfort. In response to this situation, the Community Service Lecture (KPM) team from the University of Al-Quran Science developed an innovation in making aromatherapy candles made from used cooking oil as a natural solution to eliminate the smell of cages. This initiative not only aims to overcome the odor problem, but also to utilize household waste into useful products, create economical and environmentally friendly solutions, and improve the quality of life of village communities. This program is carried out through a series of activities including socialization, aromatherapy candle making training, product trials, and basic entrepreneurship training. Early results show effectiveness in reducing cage odors, improving home comfort, and creating a healthier environment. Furthermore, this program increases public awareness about waste management, encourages active participation in maintaining environmental cleanliness, and opens up new economic opportunities. This simple but impactful innovation has the potential to be applied in other areas with similar problems, promoting a sustainable approach in addressing environmental challenges at the household level while empowering local communities.

Used cooking oil cannot be reused due to its changed physical and chemical structure, or commonly referred to as “minyak jelantah”. Repeated use of minyak jelantah can pose a risk of various diseases. Meanwhile, “minyak jelantah” is included in waste that is difficult to decompose if it is just thrown away. The utilization of used cooking oil into candles is a solution to this problem. Based on research using observation methods in Sarimukti Village residents, and experimental research methods and documentation, minyak jelantah waste can be reduced by being utilized into aromatherapy candles. Based on the organoleptic test, the results show that the color is not suitable, while the shape and smell are suitable based on the concentration of stearic acid and telon oil added. Based on the burn time, the more telon oil added, the faster the candle runs out.
