Abstract
Kangkung merupakan salah satu jenis sayuran yang banyak digemari oleh masyarakat karena memiliki kandungan gizi serta mudah dalam pembudidayaanya. Permintaan konsumsi kangkung yang meningkat, terutama jenis kangkung darat menyebabkan kegiatan budidaya kangkung perlu dioptimalkan. Salah satu upaya yang dapat dilakukan adalah melakukan optimalisasi pada media tanam yang diimbangi dengan mengatur jumlah tanaman kangkung per petak tanam. Penambahan pupuk kompos sebagai bahan campuran untuk media tanam kangkung dapat menjadi pilihan yang tepat, sebab kompos merupakan hasil fermentasi bahanbahan organik yang kaya akan unsur hara. Pengaturan jumlah tanaman juga mampu mengurangi kompetisi penyerapan unsur hara, cahaya, dan air antar tanaman. Oleh karena itu, penelitian kemudian dilakukan dengan memberikan kombinasi media tanam dan kerapatan tanaman yang berbeda pada tanaman kangkung darat. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh perlakuan, serta memperoleh pertumbuhan dan hasil tanaman kangkung darat, dengan hipotesis bahwa kombinasi media tanam tanah 600g dan kompos 300g/ polybag + 4 biji/ lubang tanam, mampu memberikan pengaruh terbaik pada pertumbuhan dan hasil tanaman kangkung darat. Penelitian dilaksanakan pada bulan September - November 2022, di Desa Pandanrejo, Kecamatan Bumiaji, Kota Batu. Alat yang akan digunakan antara lain sekop, ember, penggaris, meteran, label, alat tulis, timbangan analitik digital, dan kamera, dengan bahan penelitian yang meliputi pupuk organik, tanah, polybag ukuran 30 cm x 30 cm, air, insektisida berbahan aktif sipermetrin, pupuk majemuk NPK (16:16:16), dan benih kangkung darat tipe Bangkok LP-1. Metode yang digunakan dalam penelitian ini yaitu RAK (Rancangan Acak Kelompok) yang terdiri dari 9 perlakuan diantaranya A1 = tanah + 2 biji/ lubang tanam, A2 = tanah + 4 biji/ lubang tanam, A3 = tanah + 6 biji/ lubang tanam, A4 = 5 : 1 tanah dan kompos + 2 biji/ lubang tanam, A5 = 5 : 1 tanah dan kompos + 4 biji/ lubang tanam, A6 = 5 : 1 tanah dan kompos + 6 biji/ lubang tanam, A7 = 2 : 1 tanah dan kompos + 2 biji/ lubang tanam, A8 = 2 : 1 tanah dan kompos + 4 biji/ lubang tanam, dan A9 = 2 : 1 tanah dan kompos + 6 biji/ lubang tanam. Pada 9 perlakuan, dilakukan 3 kali ulangan sehingga diperoleh 27 satuan percobaan. Parameter pertumbuhan dan hasil yang diamati antara lain tinggi tanaman, jumlah daun, luas daun, kandungan klorofil, bobot segar total tanaman, bobot segar konsumsi tanaman, bobot segar akar, dan panjang akar tanaman kangkung darat. Data yang diperoleh kemudian dianalisis dengan menggunakan analisis ragam (uji F dengan taraf 5%) untuk mengetahui adanya pengaruh perlakuan yang diberikan dan dilanjutkan dengan uji BNJ taraf 5%. Berdasarkan hasil pengamatan dan análisis data yang telah dilakukan, diperoleh hasil bahwa perlakuan terbaik ditunjukkan pada kombinasi 2 : 1 tanah dan kompos + 4 biji/ lubang tanam, yang dibuktikan pada parameter tinggi tanaman i (33,50 cm), jumlah daun/ tanaman (86,67 helai), luas daun/ tanaman (2195,37 cm2 ), bobot segar total tanaman (446,33 g/ polybag), bobot segar konsumsi tanaman (357,67 g/ polybag), bobot segar akar (56 g), dan panjang akar (38 cm)
English Abstract
Water spinach is a type of vegetable that is widely enjoyed by the public because it has nutritional content and is easy to cultivate. The increasing demand for water spinach consumption, especially for land-grown water spinach, has led to the need for optimization of water spinach farming. One of the efforts that can be taken is to optimize the planting media while also regulating the number of water spinach plants by the planting area. The addition of compost as a mixture for the planting media can be a good option because compost is the result of the fermentation of organic materials that are rich in nutrients. Regulating the number of plants can also reduce competition for the absorption of nutrients, light, and water among plants. Therefore, the research is then carried out by giving different combinations of planting media and plant density to land-grown water spinach. The aim of this study is to determine the effect of the treatment and to obtain the best combination of treatment that can provide the best effect on the growth and yield of land-grown water spinach, with the hypothesis that the combination of 600g of soil planting media and 300g/polybag of compost + 4 seeds/planting hole can provide the best effect on the growth and yield of land-grown water spinach. The research was conducted in September - November 2022, in Pandanrejo Village, Bumiaji District, Batu City. The tools used include a shovel, bucket, ruler, meter, label, writing tools, digital analytical scale, and camera, with research materials including organic fertilizer, soil, 30 cm x 30 cm polybag, water, Insecticide with active ingredients of cypermethrin, NPK (16:16:16) compound fertilizer, and land-grown water spinach seeds variety Bangkok LP-1. The method used in this research is RAK (Randomized Block Design) consisting of 9 treatments, namely A1 = soil + 2 seeds/ planting hole, A2 = soil + 4 seeds/ planting hole, A3 = soil + 6 seeds/ planting hole, A4 = 5 : 1 soil and compost + 2 seeds/ planting hole, A5 = 5 : 1 soil and compost + 4 seeds/ planting hole, A6 = 5 : 1 soil and compost + 6 seeds/ planting hole, A7 = 2 : 1 soil and compost + 2 seeds/ planting hole, A8 = 2 : 1 soil and compost + 4 seeds/ planting hole, and A9 = 2 : 1 soil and compost + 6 seeds/ planting hole. In the 9 treatments, 3 repetitions were carried out, resulting in 27 experimental units. The growth and yield parameters observed include plant height, the number of leaves, leaf area, chlorophyll content,fresh weight of total plant, fresh weight of plant consumption, root fresh weight, and root length of land-grown water spinach plants. The data obtained were then analyzed using analysis of variance (F test at 5%) to determine the effect of the treatments given and followed by BNJ test at 5%. Based on the observations and data analysis that have been carried out, it was found that the treatment of combining soil planting media with compost as well as regulating the number of seeds planted, provides a significant effect on the growth and yield of land-grown waterspinach plants. The best treatment was shown iii in the combination of 2 : 1 soil and compost + 4 seeds/planting hole, which was proven in the parameters of plant height (33,50 cm), the number of leaves/ plant (86,67 helai), leaf area/ plant (2195,37 cm2 ), fresh weight of total plant (446,33 g/ polybag), fresh weight of plant consumption (357,67 g/ polybag), root fresh weight (56 g), and root length (38 cm).
