Abstract

Disposable baby diaper waste causes water and soil pollution when disposed in rivers, drains, streets, ground, and other places. This condition is triggered by the lack of awareness of disposable baby diaper waste management by the community, especially youngmothers who have toddlers. An appropriate solution is needed to overcome this problem and reduce the negative impact on the environment. This activity aims to introduce a waste management approach and determine the impact of the introduction of the approach in overcoming the waste problem at Tanjungrejo Village river, Madiun District, Madiun Regency, East Java Province. The research applied a qualitative method with observation and interview approach. The research sample was selected by using a purposive sampling method. Based on observations, each mother mostly threw two or three disposable baby diapers used by toddlers at landfills. Many mothers still do not know how to reduce the growing amount of disposable baby diaper waste. Media posters,presentation slides, and demonstrations of the process of making pots and ornamental plant media were carried out in the implementation of the socialization on July 2023 at the Tanjungrejo Village Head Office. Through this socialization, all mothers who have been interviewed express interest in trying and practicing the process of disposable baby diaper waste into pots and ornamental plant media. Therefore, this socialization activity can be a breakthrough innovation in the form of utilizing disposable babydiaper waste into pots and ornamental plant media.

Abstract

Bullying in the school environment is an emerging issue that needs to be taken care of by various parties. It will cause a negative impact on the future of both the perpetrator and the victim. Children may grow up with unstable emotions and have low empathy for others. The purpose of this activity is to introduce basic emotions and anti-bullying knowledge as an effort to increase empathetic awareness in the community in preventing bullying. Prospective comparative study with an observation and interview was carried out as the methodology, teachers, and parents. The research sample was selected using a purposive sampling method. Based on observations, it was found that there are behaviors that indicate bullying in the school environment. In addition, students were also found to have poor empathy and emotional management. The activity of introducing basic emotions and anti-bullying behavior utilized posters, mini games, and attaching stickers. This activity is targeted for grade 5 elementary school students because they are already able to recognize their emotions, and their experience will be an example for other students in another grade. Students, teachers, and parents who have been interviewed stated that this emotional recognition and anti-bullying activity was excellent and had a positive impact on children's emotional development. Students increasingly understand the meaning of basic emotions and anti-bullying, recognize self-emotions, know how to express emotions, increase empathy, and create a more comfortable school environment.

Abstract

Indonesia has the potential for large solar power plants. It has relatively constant solar radiation because it is close to the equator. Besides, solar energy includes renewable energy that is more environmentally friendly and easier to apply in office areas, especially Wonogiri. However, it turns out that the solar power plant projects that have been built are not yet fully functional, and some have even failed. A lack of responsibility and maintenance causes this carried out after the project is complete. For this reason, it is necessary to estimate the reliability of these components and determine the maintenance schedule before the project is carried out. So that later they have a picture and be better prepared when this project is already underway. The fault tree method's failure factors are expected to create a picture to maintain reliability and determine the prioritized components for maintainability. For the results obtained to be more appropriate, apart from seeing the quantitative analysis output, the fault tree also needs to be adjusted to the component manual or datasheet to determine the replacement of spare parts and their maintenance. So that the resulting schedule for maintenance and replacement of spare parts. Thus, the solar power plant project that has been built will be more reliable and can be appropriately utilized.

Abstract

The development of micro-scale renewable energy power generation systems, such as micro-hydropower (MHP), often needs more consideration for sustainability during the planning stages. Many small-scale renewable energy systems have shorter-than-expected lifespans, jeopardizing Indonesia's Net Zero Emission Target for 2060 or earlier. Despite this, only some studies have examined the long-term viability of installed renewable energy generation projects, particularly MHP plants not managed by state-owned companies or PLN (Pembangkit Listrik Negara). The primary objectives of this research are to evaluate the feasibility of retrofitting and assess the potential sustainability of a decommissioned MHP in Banjarnegara, Central Java. A cash flow analysis was performed to assess techno-economic indicators. Additionally, the social-institutional dimension was analyzed through in-depth interviews with 15 stakeholders. Sustainability was evaluated using a framework of 15 indicators across technical, economic, environmental, social, and institutional dimensions. The findings revealed that among the four sustainability aspects, the social-institutional dimension scored the lowest potential sustainability at 26.67%. In contrast, the technical and environmental dimensions showed higher potential sustainability, scoring 83.7% and 87.5%, respectively. The economic dimension was deemed feasible only when the financing model accounted solely for retrofitting costs. It is crucial to consider all dimensions comprehensively. Furthermore, engaging multiple stakeholders and fostering local community awareness is vital to ensure the long-term sustainability of decentralized energy systems. This study enhances the understanding of the sustainability potential of abandoned decentralized energy systems and explores how reusing abandoned MHP facilities can support stakeholders in revitalization efforts, contributing to an increased share of renewable energy in the overall energy mix.
