ABSTRACTThis study aims to determine the yield of Chlorella sp. powder extracted using different solventsbased on the degree of polarity. In extraction process, there were 3 solvents used, namely polar solvent (methanol 70%), semi-polar (ethyl acetate 80%), and non-polar (n-hexane 80%) with ratio sample:solvent 1:2 (w/v). The result showed that Chlorella powder extracted using polar solvent (methanol 70%) obtained the highest yield (30,17%), among other solvents ethyl acetate 17,31%, and n hexane 4,21%. Therefore, polar solvent (methanol 70%) is more optimal to extract Chlorella sp. powder. Keywords: Extraction, yield of Chlorella sp. Different solvents.

In waste management, the general practice in many villages still focuses on landfilling waste which is then thrown into final disposal sites. Apart from that, burning waste is often used as an alternative to reduce the volume of existing waste. However, this method causes negative environmental impacts such as increased air pollution and soil damage around village areas. This article, with the title "Optimizing Waste Through Biopori Technology in Kota Besi Hilir Subdistrict", will explain how biopori technology can be an effective solution in dealing with waste management issues in this subdistrict. Biopori technology works by speeding up the process of decomposing waste and turning it into compost that is useful for farmers and local communities. The approach applied in this project consists of two phases: first, a persuasive approach, which involves outreach to increase public awareness and interest regarding biopore holes; second, a practical approach, where students are directly involved in the process of making biopore holes. From the results of this activity, a biopore hole has been installed as an example that can be adopted and further developed by the community. Apart from that, solid organic fertilizer is produced that can be used by farmers, and there has been a change in mindset in the way people manage their waste.

Islamic Religious Education (PAI) plays an important role in forming the character and morals of students in Indonesia. However, its implementation often encounters various obstacles which cause PAI learning to be less than optimal. This research aims to analyze the obstacles that exist in implementing PAI in Indonesian schools, with a focus on aspects of learning that are not optimal. This research uses a qualitative approach with a case study method in several schools in Indonesia, which involves interviews with PAI teachers, students, and school officials, as well as direct observation of the learning process. The research results show that there are several significant obstacles in implementing PAI, including the lack of competence of PAI teachers, limited educational resources, and a lack of appropriate learning support facilities. Apart from that, low student motivation factors, the influence of the family and social environment, and limited time allocated for PAI in the curriculum also contribute to less-than-optimal learning. This research reveals that although PAI has a strategic role in education, external and internal factors in schools need to receive more attention so that the learning process can run effectively. Therefore, this research recommends increasing training for PAI teachers, providing adequate facilities, and strengthening the role of parents and the community in supporting religious learning in schools.

This study aims to examine the strengthening of Islamic-based character education through a literature study approach, by tracing the relationship between Islamic values and the Islamic psychology approach in shaping students' personalities. The method used is descriptive qualitative with content analysis techniques on scientific literature published in 2018–2025. The results of the study found ten main themes that underlie the formation of Islamic character, including the values of monotheism, the morals of the Prophet Muhammad, purification of the soul (tazkiyatun nafs), habituation of worship, spiritual balance, and teacher role models. Character in Islam is seen as a manifestation of spiritual, moral, and emotional integrity, not just normative behavior. This study concludes that the success of character education is largely determined by the synergy between the roles of teachers, families, and curriculum that are integrated and relevant to the challenges of the digital era. Therefore, an adaptive education strategy is needed but still rooted in Islamic values, as well as training for teachers and parents as moral role models. This study confirms that the Islamic-based character education approach can be a conceptual solution in addressing the moral crisis among the younger generation.

Penelitian ini bertujuan untuk mendeskripsikan peran pojok baca dalam meningkatkan kemampuan membaca siswa di SD Negeri 027950 Binjai. Latar belakang penelitian ini dilandasi oleh rendahnya minat baca siswa sekolah dasar dan perlunya inovasi dalam penyediaan sarana literasi yang mendukung proses belajar. Pojok baca dipandang sebagai alternatif strategis dalam menciptakan lingkungan literasi yang menyenangkan dan efektif. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan teknik pengumpulan data berupa wawancara mendalam, observasi partisipatif, dan dokumentasi. Subjek penelitian terdiri dari guru kelas dan siswa kelas III dan IV. Hasil penelitian menunjukkan bahwa implementasi pojok baca memberikan dampak positif terhadap peningkatan minat dan kemampuan membaca siswa. Siswa menjadi lebih tertarik membaca karena suasana pojok baca yang menarik dan ketersediaan buku yang sesuai dengan tingkat perkembangan mereka. Selain itu, frekuensi dan durasi membaca siswa meningkat secara signifikan, dan siswa menunjukkan pemahaman bacaan yang lebih baik. Guru juga memiliki peran penting dalam mendampingi kegiatan membaca dan memfasilitasi diskusi pasca membaca. Namun demikian, ditemukan pula beberapa faktor penghambat, seperti keterbatasan jumlah buku, waktu pengelolaan yang terbatas oleh guru, serta kurangnya keterlibatan orang tua dalam mendukung kebiasaan membaca di rumah. Penelitian ini menyimpulkan bahwa pojok baca merupakan media literasi yang efektif apabila dikelola dengan baik dan mendapat dukungan dari semua pihak. Rekomendasi diberikan untuk penguatan koleksi bacaan, peningkatan peran guru, dan kolaborasi dengan orang tua guna memperkuat budaya literasi siswa.

Film merupakan salah satu alat komunikasi massa yang berfungsi menyampaikan pesan kepada khalayak. Penelitian ini menganalisis resepsi audiens terhadap kontroversi film Laura yang diangkat dari kisah nyata influencer Laura Anna. Film ini menggambarkan perjuangan Laura melawan ketidakadilan setelah mengalami kecelakaan tragis. Gaya hidup Laura sebelum kecelakaan, termasuk kehidupan malam dan hubungan intim dengan pacarnya, memicu beragam reaksi publik. Penelitian menggunakan metode deskriptif kualitatif dan teori resepsi Stuart Hall untuk mengkaji bagaimana penonton menafsirkan pesan film melalui tiga posisi: hegemonik dominan, negosiasi, dan oposisi. Data dikumpulkan melalui wawancara mendalam dengan lima informan yang telah menonton film. Hasil penelitian menunjukkan bahwa satu informan berada pada posisi hegemonik dominan dan menganggap Laura sebagai sosok inspiratif. Tiga informan berada pada posisi negosiasi, mengakui pesan utama film tetap tersampaikan meski disertai kontroversi. Satu informan berada pada posisi oposisi, menilai film ini hanya mengeksploitasi tragedi tanpa memberikan solusi jelas. Temuan ini menegaskan bahwa penafsiran pesan media sangat bergantung pada latar belakang dan perspektif audiens.
