Abstract

Penggunaan tanaman jagung yang toleran terhadap salinitas merupakan langkah praktis dan ekonomis, sehingga perlu perakitan varietas jagung toleran salinitas dan berdaya hasil tinggi.Penelitian ini bertujuan untuk mengetahui respon beberapa genotipe jagung respon beberapa genotipe jagung tahap perkecambahan dan pertumbuhan awal terhadap salinitas. Penelitian ini di laksanakan di Tarakan, mulai bulan Oktober sampai dengan Desember 2012, menggunakan Rancangan Acak Kelompok 2 faktor yaitu faktor genotip jagung (G) dan faktor  konsentrasi NaCl (K). Faktor Genotipe jagung (G) terdiri dari 4 aras yaitu : G1 (hasil persilangan varietas NK 33 x Bisi 12), G2 (hasil persilangan varietas NK 33 x DK 979), G3 (hasil persilangan P3 x Bisi 12), G4 (hasil persilangan DK 979 x Bisi 12). Faktor  Konsentrasi NaCl (K) yang terdiri dari 4 aras yaitu : K0 (NaCl 0 ppm), K1 (NaCl 500 ppm), K2 (NaCl  1000 ppm), K3 (NaCl 1500 ppm).Hasil penelitian menunjukkan bahwa perlakuan salinitas (kosentrasi NaC) dan perbedaan genotip berpengaruh tidak nyata terhadap parameter laju perkecambahan (hari), persentase perkecambahan benih (%), dan tinggi bibit (cm). Perlakuan salinitas (kosentrasi NaCl) berpengaruh nyata terhadap parameter tinggi bibit (cm) dan panjang akar utama bibit (cm), tetapi perbedaan genotip berpengaruh tidak nyata.

Abstract

The Strengthening Pancasila Student Profile Project (P5) is part of the implementation of the Merdeka Belajar Curriculum, which encourages students to think critically and contribute positively to society. This community service activity aimed to improve students' knowledge and skills in preparing planting materials for urban farming systems and to provide hands-on experience that supports the implementation of P5 at SMP Muhammadiyah 2 Tarakan, North Kalimantan. The participants were 60 students from classes 8A and 8B of SMP Muhammadiyah 2 Tarakan. The activities consisted of classroom socialization, training, and mentoring through hands-on practice on the school grounds, covering planting materials, growing media, seed sowing, preparation of hydroponic nutrient solution, and transplanting. The activity was evaluated descriptively through direct observation of students' participation, interest, enthusiasm, and ability to perform the practical stages. The evaluation showed that all planned stages of the activity (100%) were completed successfully. Students demonstrated high interest and enthusiasm and showed improved knowledge, understanding, and practical skills, particularly in preparing planting materials and carrying out cultivation practices in urban farming systems. The activity also supported students' awareness of food sustainability issues and the development of entrepreneurial insight
