Abstract

Penelitian ini bertujuan mengevaluasi respons pertumbuhan dan hasil jagung terhadap pemberian pupuk organik di lahan kering masam Kabupaten Boalemo, Provinsi Gorontalo. Tujuan spesifiknya adalah: (1) menentukan dosis pupuk organik optimal, (2) mengidentifikasi varietas jagung terbaik, dan (3) menemukan kombinasi optimal antara dosis pupuk dan varietas. Penelitian dilaksanakan dengan rancangan faktorial dua faktor menggunakan Rancangan Petak Terpisah (RPT), melibatkan tiga varietas jagung (Jakarin, NK 212, Pulut Uri 1) dan tiga dosis pupuk organik (O1=0 g/tanaman; O2=200 g/tanaman; O3=300 g/tanaman). Analisis data dilakukan melalui sidik ragam (ANOVA) dan uji lanjut DMRT (α=5%). Hasil penelitian menunjukkan bahwa dosis pupuk organik O2 memberikan respons terbaik pada tinggi tanaman (201,51 cm), jumlah daun (10,07 helai), diameter batang (18,42 mm), panjang tongkol (17,89 cm), bobot 100 butir (38,13 g), dan produksi per hektar (13,68 ton/ha). Varietas NK 212 dan Jakarin unggul dalam parameter agronomi dibandingkan Pulut Uri 1, dengan NK 212 mencatatkan hasil tertinggi pada kombinasi dengan O2. Interaksi antara varietas dan dosis pupuk tidak selalu signifikan, tetapi pemilihan varietas tetap menjadi faktor kritis untuk adaptasi di lahan masam. Pupuk organik dosis O2 efektif meningkatkan pH tanah, mengurangi toksisitas Al³⁺, serta meningkatkan ketersediaan hara N, P, dan K. Rekomendasi utama adalah penggunaan varietas NK 212 bersama pupuk organik O2 sebagai strategi optimal untuk produktivitas jagung di lahan kering masam. Penelitian ini memberikan basis teknologi budidaya jagung ramah lingkungan yang dapat diterapkan di wilayah dengan kondisi serupa.

Abstract

Ideally in the learning process students are expressed interest if students make their learning as an interest, because interest will make students learn seriously. The reality is that students are lacking in enthusiasm or not motivated to learn well, so it needs a method that can increase students' learning interest in the material in question. This study has obtained results that the use of team quiz methods can improve student learning outcomes. This can be seen from the results of the analysis in cycle I and cycle II, showing an increase in student learning completeness from cycle I to cycle II. This result is clearly seen from the average student learning outcomes in the first cycle with a percentage of 74.40% while in the second cycle the percentage is 89.20%. This proves that student learning completeness has increased in cycle II. This proves that learning has a classical improvement. The use of team quiz method can increase students 'interest in learning can be seen based on students' interest in the use of team quiz method in learning PAI reaches 92.4% of the total number of students. This percentage is included in the very high category. So it was concluded that there was an increase in students' learning interest in PAI learning by using the team quiz method. Students are more active and have an interest in learning because the material presented is easy to remember and understand.
