| Judul Artikel | PLIKASI ELECTRICAL CONDUCTIVITY (EC) LARUTAN NUTRISI DAN VARIETAS TERHADAP PERTUMBUHAN SERTA KUALITAS BUAH STROBERI (Fragaria × ananassa) PADA SISTEM HIDROPONIK NUTRIENT FILM TECHNIQUE (NFT) |
| Abstrak (Bhs. Indonesia) | Stroberi (Fragaria × ananassa) merupakan komoditas hortikultura bernilai ekonomi tinggi yang memiliki prospek dikembangkan di Indonesia. Permintaan stroberi yang tinggi belum sepenuhnya diimbangi dengan ketersediaan produksi. Produksi stroberi di dataran tinggi masih menghadapi fluktuasi akibat kondisi lingkungan lahan terbuka, degradasi lahan, serta gangguan hama dan penyakit. Budidaya stroberi di dataran rendah menghadapi kendala suhu lingkungan yang tinggi sehingga pertumbuhan, hasil, dan kualitas buah belum optimal. Sistem hidroponik Nutrient Film Technique (NFT) di dalam greenhouse dapat menciptakan lingkungan tumbuh yang lebih terkendali. Electrical Conductivity (EC) larutan nutrisi merupakan salah satu indikator kepekatan larutan yang menentukan ketersediaan unsur hara bagi tanaman, sehingga pengaturan EC menjadi bagian penting dalam budidaya stroberi. Penelitian ini bertujuan menganalisis pengaruh variasi EC terhadap pertumbuhan dan hasil tanaman stroberi, mendapatkan respons tiga varietas stroberi terhadap perlakuan EC, serta mengkaji interaksi antara EC dan varietas pada sistem hidroponik NFT di greenhouse dataran rendah. Penelitian dilaksanakan di Experimental Farm Fakultas Pertanian Universitas Jenderal Soedirman, Purwokerto, pada ketinggian 105–110 m dpl pada Desember 2025–Juni 2026. Penelitian menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan perlakuan EC 1,5; 2,5; dan 3,5 mS/cm serta varietas Mencir, Red Giant, dan California. Setiap kombinasi perlakuan diulang tiga kali sehingga diperoleh 27 unit percobaan dengan total 81 tanaman. Parameter yang diamati meliputi iklim mikro greenhouse, pH larutan nutrisi, tinggi tanaman, jumlah daun, jumlah buah, berat buah total, berat rata-rata buah, diameter buah, dan total padatan terlarut (°Brix). Data iklim mikro dianalisis secara deskriptif, sedangkan data pertumbuhan dan hasil dianalisis menggunakan analisis ragam (ANOVA) pada taraf 5% dan dilanjutkan dengan Duncan’s Multiple Range Test (DMRT) pada taraf 5% apabila terdapat pengaruh nyata. Hasil pengamatan menunjukkan bahwa suhu udara di dalam greenhouse lebih tinggi dibandingkan dengan suhu udara di luar greenhouse, dengan rata-rata masing-masing sebesar 32,4°C dan 28,0°C. RH di dalam greenhouse berkisar 47,2–72,4%, intensitas cahaya berkisar 1.565–20.885 lux, dan pH larutan nutrisi relatif stabil pada kisaran 6,55–6,59. Perlakuan EC berpengaruh terhadap tinggi tanaman, jumlah daun, jumlah buah, berat buah total, berat rata-rata buah, dan total padatan terlarut (°Brix), tetapi tidak berpengaruh nyata terhadap diameter buah. EC 2,5 mS/cm menghasilkan tinggi tanaman tertinggi sebesar 20,02 cm dan jumlah daun tertinggi sebesar 8,74 helai. EC 1,5 mS/cm menghasilkan jumlah buah tertinggi sebesar 1,19 buah/tanaman, berat buah total tertinggi sebesar 6,67 g/tanaman, berat rata-rata buah tertinggi sebesar 5,44 g/buah, dan total padatan terlarut tertinggi sebesar 8,97 °Brix. Varietas berpengaruh nyata terhadap tinggi tanaman, jumlah daun, dan diameter buah, tetapi tidak berpengaruh nyata terhadap jumlah buah, berat buah total, berat rata-rata buah, dan total padatan terlarut. Red Giant menghasilkan tinggi tanaman tertinggi sebesar 15,08 cm, jumlah daun tertinggi sebesar 7,56 helai, dan diameter buah terbesar sebesar 22,25 mm. California menghasilkan diameter buah sebesar 21,95 mm, sedangkan Mencir menghasilkan diameter buah sebesar 20,21 mm. Interaksi antara EC dan varietas tidak berpengaruh nyata terhadap seluruh parameter pengamatan. Hasil penelitian menunjukkan bahwa pengaturan EC perlu disesuaikan dengan respons pertumbuhan dan hasil tanaman untuk mendukung budidaya stroberi pada sistem hidroponik NFT di greenhouse dataran rendah. |
| Abtrak (Bhs. Inggris) | Strawberry (Fragaria × ananassa) is a high-value horticultural commodity with good potential for development in Indonesia. High demand for strawberries has not been fully matched by adequate production. Strawberry production in highland areas remains subject to fluctuations due to open-field environmental conditions, land degradation, and pest and disease disturbances. Strawberry cultivation in lowland areas faces the challenge of high ambient temperatures, which limit plant growth, yield, and fruit quality. The hydroponic Nutrient Film Technique (NFT) system inside a greenhouse can provide a more controlled growing environment. Electrical Conductivity (EC) of the nutrient solution is an indicator of nutrient solution concentration that determines nutrient availability to plants; therefore, appropriate EC management is important for strawberry cultivation. This study aimed to analyze the effects of different EC levels on strawberry growth and yield, evaluate the responses of three strawberry varieties to EC treatments, and examine the interaction between EC and variety in an NFT hydroponic system in a lowland greenhouse. The study was conducted at the Experimental Farm, Faculty of Agriculture, Universitas Jenderal Soedirman, Purwokerto, at an elevation of 105–110 m above sea level from December 2025 to June 2026. The study used a factorial Completely Randomized Design (CRD) with three EC levels of 1.5, 2.5, and 3.5 mS/cm and three strawberry varieties, namely Mencir, Red Giant, and California. Each treatment combination was replicated three times, resulting in 27 experimental units containing a total of 81 plants. The observed parameters included greenhouse microclimate, nutrient solution pH, plant height, number of leaves, number of fruits, total fruit weight, average fruit weight, fruit diameter, and total soluble solids (°Brix). Microclimate data were analyzed descriptively, whereas growth and yield data were analyzed using analysis of variance (ANOVA) at the 5% significance level, followed by Duncan’s Multiple Range Test (DMRT) at the 5% significance level when significant treatment effects were detected. The results showed that the air temperature inside the greenhouse was higher than that outside the greenhouse, with average temperatures of 32.4°C and 28.0°C, respectively. Relative humidity (RH) inside the greenhouse ranged from 47.2–72.4%, light intensity ranged from 1,565–20,885 lux, and the nutrient solution pH remained relatively stable at 6.55–6.59. EC significantly affected plant height, number of leaves, number of fruits, total fruit weight, average fruit weight, and total soluble solids (°Brix), but did not significantly affect fruit diameter. An EC of 2.5 mS/cm produced the highest plant height of 20.02 cm and the highest number of leaves of 8.74 leaves. An EC of 1.5 mS/cm produced the highest number of fruits at 1.19 fruits/plant, total fruit weight at 6.67 g/plant, average fruit weight at 5.44 g/fruit, and total soluble solids at 8.97 °Brix. Variety significantly affected plant height, number of leaves, and fruit diameter, but did not significantly affect number of fruits, total fruit weight, average fruit weight, or total soluble solids. Red Giant produced the highest plant height of 15.08 cm, the highest number of leaves of 7.56 leaves, and the largest fruit diameter of 22.25 mm. California produced a fruit diameter of 21.95 mm, whereas Mencir produced a fruit diameter of 20.21 mm. The interaction between EC and variety did not significantly affect any of the observed parameters. The results indicate that EC management should be adjusted according to plant growth and yield responses to support strawberry cultivation in an NFT hydroponic system in a lowland greenhouse. |
