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.

This study explores the effectiveness of STEM education in developing spatial thinking skills in elementary school students. The study employs a quasi-experimental design involving two groups: an experimental group that received STEM intervention and a control group following the standard curriculum. The results indicate that the experimental group experienced significant improvements in visualization, spatial relationship understanding, and spatial object manipulation compared to the control group. These improvements are primarily to technology, such as 3D simulations and design software, which help students comprehend complex spatial concepts. Further statistical analysis supports these findings, showing significant differences between the experimental and control groups. These findings underscore the importance of integrating STEM education into the curriculum to enhance students' spatial skills, which are critical in various science and technology disciplines. However, challenges in implementation, such as a need for more resources and teacher training, must be addressed to ensure the program's effectiveness across different educational contexts.

The principal's leadership is an important component in the school, because it sets various policies and rules that will guide the school. One of the determinants of the progress of an educational institution is the leadership of the school principal. Effective school principal leadership must be able to carry out the vision and policies of the government and those that have been determined together. However, in reality in the field, subordinates (teachers and administrative staff) do not easily accept and implement the government's vision and policies or school policies that have been mutually agreed upon. The proof is that there are still many schools that have not been able to implement the vision in the form of action, sometimes the decisions taken do not involve subordinates, communication between leaders and subordinates is not good so that recognizing each member/subordinate will be difficult, so that leadership will not bring influence or change to the community. the institution. Basically, all input, policies and new breakthroughs are more easily accepted if they are conveyed using an approach based on the local customs/wisdom of the East Sumba community. This is caused by the culture or local wisdom of the East Sumba people which is still very influential in all aspects of life. A leader must be able to carry out policies that continue to be determined by the government by paying attention to the local wisdom of the community which has been embedded and become a guideline for social life before there is a government policy. So that culture and local wisdom can be implemented simultaneously, when policies are unable to solve a problem, that's where the leader will take an approach based on the local wisdom of the community. Vice versa, when local wisdom cannot solve a problem, then government policy will be used to solve the problem. This research topic is divided into two, namely, leadership and local wisdom. The aim of this research is to analyze the relationship between leadership and local wisdom of East Sumba, describe the characteristics of leadership based on local wisdom of East Sumba, and analyze the effectiveness of the leadership of school principals based on local wisdom of East Sumba at SMA Negeri 1 Pandawai
