Abstract

Tujuan penelitian ini adalah untuk mengetahui kandungan unsur hara pupuk organic cair dari limbah kulit pisang. Unsur hara yang dianalisis yaitu kandungan Nitrogen (N), Fosfor (P), Kalium (K), dan Magnesium (Mg). Metode penelitian yang digunakan yaitu eksperimental laboratoris. Tahapan dari penelitian ini meliputi mencari sumber materi mengenai proses fermentasi pupuk organik cair dari limbah kulit pisang mencari penelitian sejenis, menentukan variabel, persiapan percobaan, melakukan percobaan, analisa parameter N, P,K dan Mg. Data yang diperoleh dibuat tabel dan grafik hasil analisa, dan membuat kesimpulan. Berdasarkan hasil analisa uji laboratorium pada sampel pupuk organic cair dari limbah kulit pisang menunjukkan tingkat pH yang menguntungkan nilai Nitrogen, Fosfor, Kalium dan Magnesium sehingga cocok pilihan untuk pemupukan tanaman organik. Konsentrasi Nitrogen (N) sebesar 1.3%. Konsentrasi fosfor (P) pada pupuk organik cair ini juga memiliki jumlah yang besar. Fosfor (P) kandungan dalam pupuk ini adalah 0.02%. Kalium (K) kandungan dalam pupuk ini adalah 3.01%.  Kandungan Magnesium (Mg) dalam pupuk ini adalah 0.16%.

Abstract

Green education is integrated into chemistry learning to support the green economy, as it offers numerous applications in everyday life, including waste management and sustainable reforestation programs. Based on the Merdeka Curriculum, one aspect of chemistry learning in grade 10 is green chemistry, which explores global issues and problem-solving. Science skills are closely linked to green education in chemistry learning, as students gain scientific knowledge and attitudes from the theories they learn. All these efforts are directed toward achieving the Sustainable Development Goals (SDGs). The research used a quasi-experimental Design. The study had two groups, the experimental and the control groups. The sample was SMA Negeri 1 Gunung Meria, Deli Serdang Regency students. The research instruments used were essay tests and observations. The results of the posttest t-test analysis between the control and the experimental group at a significance level of 0.05, then 0.00 <0.05, then Ho is rejected and Ha is accepted. The results of the students' entrepreneurial character scores can be seen in Figure 1, where the experimental class has an average score of 77.70 and the control class 42.85. The results of the study can be concluded that education has a significant influence on students' science process skills. Students' entrepreneurial character shows a substantial difference, in that in the experimental class, there is good development.
