Abstract

Limbah cair yang dihasilkan dari tempat pembuangan akhir (TPA) sering kali mengandung logam berat seperti seng (Zn), yang menimbulkan risiko signifikan terhadap lingkungan dan kesehatan manusia. Berdasarkan hasil analisis AAS terhadap konsentrasi Zn di TPA Antang, didapatkan konsentrasi Zn sebesar 0,1015 mg/L. Nilai tersebut tidak memenuhi ketentuan yang ditetapkan dalam Peraturan Pemerintah Republik Indonesia Nomor 22 Tahun 2021 tentang Penyelenggaraan Perlindungan Lingkungan Hidup dan Pengelolaan Baku Mutu Air Nasional, khususnya mengenai baku mutu air limbah Zn sebesar 0,05 mg/L. Salah satu metode alternatif untuk menurunkan konsentrasi Zn tersebut adalah melalui proses adsorpsi dengan arang aktif ampas kopi. Aktivasi secara kimia menggunakan HCI untuk meningkatkan sifat adsorpsi. Ampas kopi dapat diubah menjadi arang aktif karena kandungan karbon yang dapat menyerap logam. Variasi yang digunakan waktu kontak selama 90 menit, 120 menit, 150 menit, dan 180 menit. Temuan penelitian mengungkapkan bahwa arang aktif dapat menurunkan konsentrasi Zn pada limbah cair TPA Antang. Pada waktu kontak 90 menit konsentrasi logam Zn sebesar 0,0170 mg/L pada waktu kontak 120-150 menit kandungan logam Zn sebanyak 0,0146 mg/L, dan waktu kontak 180 menit sebanyak 0,0135 mg/L.

Abstract

Extracurricular activities are a vital component in the educational process that supports holistic student development, encompassing intellectual, emotional, and social growth. This study aims to analyze the management of extracurricular activities at SMA Negeri 10 Luwu Utara and its impact on student motivation and achievement. Using a qualitative research design, data collection was conducted through observations, interviews, and documentation involving extracurricular supervisors, school officials, and students. The findings reveal that the management process follows four main stages: planning, organizing, implementing, and evaluating. The structured management approach significantly enhances student skills, fosters leadership, and boosts student engagement. However, several challenges were identified, including overlapping schedules, limited funding, and time constraints, which hinder the optimal execution of extracurricular programs. The study emphasizes that innovative management strategies, supported by the active role of teachers, school officials, and parents, are essential to maximize the benefits of extracurricular activities. Furthermore, the research highlights that effective extracurricular management not only improves student motivation but also enhances academic performance and character development. By addressing the existing challenges and strengthening collaboration among stakeholders, extracurricular activities can serve as a powerful tool to support student achievement and personal growth. This study provides valuable insights for educational institutions in developing more effective strategies to manage extracurricular programs and create a supportive learning environment that nurtures student potential in both academic and non-academic aspects.
