RINGKASAN Sabila Enggar Muthaharuna. 165040207111049. Pengaruh Dosis Pupuk NPK dan Biourin Kelinci terhadap Pertumbuhan dan Hasil Tanaman Selada (Lactuca sativa L.). Di bawah bimbingan Prof. Dr. Ir. Moch. Dawam Maghfoer, S.U. sebagai Pembimbing Utama. Selada merupakan salah satu tanaman sayuran yang penting dalam kategori sayuran daun. Tanaman ini memiliki sedikit rasa manis dan renyah, mengandung gizi yang cukup tinggi, dan memiliki berbagai manfaat bagi kesehatan. Oleh sebab itu selada sangat digemari oleh masyarakat. Kandungan gizi dalam seratus gram daun tanaman selada terdiri dari 96% air, 1,4 g protein, 2,2 g karbohidrat, 1,1 g serat pangan, 0,2 g lemak, dan 1,2 g abu (Noumedem et al., 2017). Saat ini kesadaran masyarakat akan pola hidup sehat dan jumlah penduduk Indonesia kian bertambah sehingga menyebabkan terjadinya peningkatan kebutuhan konsumen akan tanaman selada. Impor tanaman sayuran yang cenderung meningkat tiap tahun serta sempitnya lahan pertanian memerlukan solusi budidaya tanaman selada yang tepat dan dapat diterapkan di areal yang terbatas. Salah satunya yaitu budidaya tanaman selada di polybag yang dapat diterapkan di pekarangan rumah yang sempit. Budidaya dalam polybag perlu memperhatikan ketersediaan unsur hara dalam media tanam. Penambahan unsur hara dalam media tanam dapat dilakukan dengan beberapa cara, seperti pemberian pupuk NPK dan biourin kelinci. Berdasarkan hal tersebut, penelitian ini dilakukan untuk mendapatkan dosis pupuk NPK dan biourin kelinci yang optimum bagi pertumbuhan dan hasil tanaman selada. Penelitian dilaksanakan pada bulan Maret hingga Mei 2020 di Greenhouse Lanud Abdulrachman Saleh yang berlokasi di Kecamatan Pakis, Kabupaten Malang. Alat yang digunakan dalam penelitian ini antara lain tray persemaian, gembor, LAM (Leaf Area Meter), klorofil meter SPAD (Soil Plant Analysis Development), alat tulis, timbangan digital, kamera, meteran, jangka sorong, timba plastik, cetok, cangkul, dan gelas ukur. Bahan yang digunakan antara lain benih tanaman selada varietas Grand Rapids, polybag berukuran 30 cm x 30 cm, previcur N, air, tanah, pupuk kandang sapi, pupuk NPK mutiara (16:16:16), dan biourin kelinci. Penelitian disusun menggunakan Rancangan Acak Kelompok (RAK) faktorial dengan perlakuan yang terdiri dari lima taraf dosis pupuk NPK: 0 kg ha-1 atau 0 g tanaman-1 (P0), 225 kg ha-1 atau 1,40 g tanaman-1 (P1), 450 kg ha-1 atau 2,81 g tanaman-1 (P2), 675 kg ha-1 atau 4,21 g tanaman-1 (P3), dan 900 kg ha-1 atau 5,62 g tanaman-1 (P4) serta dua taraf penambahan biourin kelinci: tanpa penambahan biourin kelinci (K0) dan penambahan biourin kelinci 135 ml tanaman-1 (K1). Pengamatan pertumbuhan dilakukan secara non destruktif yang terdiri dari tinggi tanaman, jumlah daun, diameter batang, indeks klorofil, dan luas daun. Pengamatan panen terdiri dari panjang akar, bobot segar total, dan bobot konsumsi. Data yang diperoleh dari hasil pengamatan dianalisis dengan menggunakan Analisis Ragam dengan taraf 5%. Apabila terdapat pengaruh maka dilanjutkan dengan uji lanjut Beda Nyata Jujur (BNJ) pada taraf 5%. Hasil penelitian menunjukkan bahwa interaksi antara pupuk NPK dan biourin kelinci berpengaruh nyata terhadap pertumbuhan dan hasil tanaman selada yakni pada parameter tinggi tanaman 25 HST, luas daun 28 HST, panjang akar, bobot segar total, dan bobot segar konsumsi. Perlakuan pupuk NPK dengan dosis 675 kg ha-1 atau 4,21 g tanaman-1 yang dikombinasikan dengan biourin kelinci 135 ml ii tanaman-1 memberikan hasil yang lebih tinggi sebesar 22% dan berbeda nyata daripada perlakuan tanpa dipupuk NPK pada parameter pengamatan bobot segar total tanaman selada. Perlakuan pupuk NPK pada berbagai dosis yang diberikan pada tanaman selada dapat meningkatkan pertumbuhan dan hasil tanaman selada pada beberapa parameter pengamatan meliputi tinggi tanaman umur 28 HST, indeks klorofil umur 14 serta 28 HST, luas daun umur 14 HST, serta diameter batang umur 28 HST. Sedangkan perlakuan biourin kelinci memberikan hasil yang berpengaruh nyata pada beberapa parameter meliputi indeks klorofil umur 14 HST, luas daun umur 14 HST, dan diameter batang umur 28 HST.

SUMMARY Sabila Enggar Muthaharuna. 165040207111049. The Effect of NPK Fertilizer Dosage and Rabbit Biourine on Growth and Yield of Lettuce (Lactuca sativa L.). Supervised by Prof. Dr. Ir. Moch. Dawam Maghfoer, S.U. as The Main Supervisor. Lettuce is one of the vegetable plants which is important in the leaf vegetables category. This plant has a slightly sweet and crunchy taste, contains quite high nutrition, and has various health benefits. Therefore, lettuce is very popular in society. The nutritional content in one hundred grams of lettuce leaves consists of 96% water, 1.4 g proteins, 2.2 g carbohydrates, 1.1 g dietary fiber, 0.2 g fat, and 1.2 g ash (Noumedem et al., 2017). Nowadays the society's awareness of healthy lifestyles and the number of Indonesia's population are increasing which leads to a higher demand of lettuce consumer. The import of vegetables that tend to increase every year and the narrow agricultural land requires appropriate lettuce cultivation solutions and can be applied on the limited areas. One of the solutions is cultivation of lettuce in a polybag which can be applied in a narrow yard at home. Cultivation in polybags need to be aware of the availability of nutrients in the planting media. Addition of nutrients in the planting media can be done in several ways, for instances the addition of NPK fertilizer and rabbit biourine. This study will be conducted to get the optimum dose of NPK fertilizer and rabbit biourine on growth and yield of lettuce. The research was conducted in March until May 2020 at Greenhouse Lanud Abdulrachman Saleh which located in Pakis District, Malang. The tools that were used in this study such as seedbed trays, watering can, LAM (Leaf Area Meters), chlorophyll meter SPAD (Soil Plant Analysis Development), stationery, analytical scales, camera, ruler, gauge, caliper, plastic bucket, shovel, hoe, and measuring cup. Materials that were used such as Grand Rapids lettuce seeds, polybags 30 cm x 30 cm, previcur N, water, soil, cow manure, NPK mutiara (16:16:16) fertilizer, and rabbit biourine. The study was arranged with a factorial randomized block design in a treatment consisting of five levels of NPK fertilizer dosage: 0 kg ha-1 or 0 g plant-1 (P0), 225 kg ha-1 or 1,40 g plant-1 (P1), 450 kg ha-1 or 2,81 g plant-1 (P2), 675 kg ha-1 or 4,21 g plant-1 (P3), dan 900 kg ha-1 or 5,62 g plant-1 (P4) and two levels of rabbit biourine addition: without the addition of rabbit biourine (K0) and with the addition of rabbit biourine 135 ml plant-1 (K1). Growth observation that was observed consist of non-destructive observation variables such as plant height, number of leaves, stem diameter, chlorophyll index, and leaf area. Harvesting observation consist of root length, total fresh weight, and consumption weight. Observation datas is analyze using Analysis of Variance (F test) at 5% level. If the result is significantly different, then proceed with further testing of Honestly Significant Difference (HSD) at 5% level. The results showed that the interaction between NPK fertilizer and rabbit biourine had a significant effect on the growth and yield of lettuce, such as on the plant height 25 DAP, leaf area at 28 DAP, root length, total fresh weight, and fresh consumption weight. NPK fertilizer treatment with a dose of 675 kg ha-1 or 4,21 g plant-1 combined with rabbit biourine 135 ml plant-1 gave higher yields by 22% and significantly different from the treatment without NPK fertilizer on the total fresh weight parameter of lettuce plants. NPK fertilizer treatment at various doses given iv to lettuce plants can increase the growth and yield of lettuce plants on several observation parameters such as plant height at 28 DAP, chlorophyll index at 14 and 28 DAP, leaf area at 14 DAP, and stem diameter at 28 DAP. While the rabbit biourine treatment gave results that significantly affected several parameters such as chlorophyll index at 14 DAP, leaf area at 14 DAP, and stem diameter at 28 DAP.
