The plastic waste problem in Indonesia has reached a severe level. Data from the National Waste Management Information System shows that Indonesia produces around 17 million tons of plastic waste yearly. However, only approximately 66.47% of this plastic waste undergoes recycling, with the remainder ending up in landfills or polluting the sea. This condition places Indonesia in second place in the world after China in terms of the amount of plastic waste produced, making it a country with a plastic waste emergency. This article discusses the development of plastic recycling machine technology as a solution to overcome the plastic waste problem in Indonesia. With a production of around 17 million tons of plastic waste per year, Indonesia faces significant challenges in plastic waste management. Low efficiency often constrains the effectiveness of plastic recycling as a solution. Therefore, this study aims to design and improve the efficiency of a plastic shredder machine. This machine uses specially designed rotating blade technology to produce high-precision plastic flakes. Additionally, we have updated the transmission system to reduce vibration and implemented other innovations to enhance the machine's capacity to shred various types of plastic. We expect this machine to decrease greenhouse gas emissions from the recycling process and lower operational costs. This study shows that the developed plastic shredder machine can work effectively and efficiently, meeting the research objectives of producing plastic flakes quickly. Thus, we expect this machine to significantly reduce plastic waste in Indonesia and support environmental conservation efforts.

The Ministry of Education, Culture, Research, and Technology (Kemdikbudristek) issued an Independent Learning policy in order to achieve quality education for all Indonesian people. Quality education focuses on developing basic competencies and character to ensure students progress in learning so that they are more competent and have character. One of the Independent Learning policies that have been launched is the Educational Report platform. The Educational Report Platform that was launched, is a platform that provides data on reports on the results of the evaluation of the education system as an improvement on previous quality report platform. This research is a descriptive qualitative study to examine how the newly launched Indonesian Educational Report platform can be utilized in data-based education planning so that the planning carried out can be more targeted and the quality of education can be improved. The results of the study have shown that the use of Educational Report in data-based planning is a tool and a way to identify root causes, reflect on educational achievements, and become a material for constructive discussions with various education stakeholders to improve the quality of education.

Management of the relationship between educational institutions and the community is essential in the development of the educational institution itself; school branding is also essential in developing educational institutions to create a good image in the eyes of the community. Therefore, the authors researched this matter at Madrasah Ibtidaiyah (MI). ) Muhammadiyah 1 Simo, Ponorogo to analyze how the madrasah public relations (PR) strategy is used and how the school branding is. This study uses a qualitative approach with interviews and observation methods to gather information. The results of this research were: 1) Simo 1 Madrasah Ibtidaiyah Muhammadiyah (MIM), Ponorogo used a strategy by creating harmonious relations between madrasahs and the community so that later both parties cared for each other and could work together in improving the quality of education. The form of concern given by the community to them includes the provision of student classrooms in residents' homes, considering that classrooms at schools are still limited, community service activities in school construction routinely every month, donations of infaq money for school facilities, and the community's willingness to assist school activities. 2) The net result is that in school branding in this industrial era, the institution has a strategy of providing good services and facilities that will create a good image of the madrasa and make people interested in the madrasa based on the school's website to inform the wider community, the programs provided among others: a) tahfidz program, b) madrasah adiwiyata, c) reading the Qur'an ummi method, d) student shuttle car, e) extracurriculars: drum-band, futsal, and badminton. In improving the school's image, its implementation requires the cooperation of all school members, parents of students and the surrounding community through the print media, namely the distribution of banners, brochures and calendars. Technology media is also used for school branding activities, such as publications on the school's official social media, WhatsApp, Facebook, tick-tock, Instagram and the school's website.
