Budidaya sayuran hidroponik dapat dijadikan salah satu alternatif dalam meningkatkan penghasilan karena memberikan keuntungan yang relatif besar dengan pasar potensial yang terus berkembang. Namun, budidaya sayuran hidroponik membutuhkan ketelitian, keterampilan khusus dan biaya produksi yang relatif tinggi. Penelitian ini bertujuan untuk menganalisis keuntungan budidaya sayuran hidroponik berdasarkan sistem budidaya hidroponik yang digunakan dan jenis sayuran yang dibudidayakan. Tiga unit instalasi hidroponik DFT dengan ukuran 2 m x 1 m x 2 m digunakan untuk membudidayakan sayuran pakcoy, caisim dan kangkung. Berdasarkan analisis efisiensi usahatani, maka budidaya sayuran hidroponik dengan sistem DFT layak diusahakan dengan rasio (B/C) untuk budidaya pakcoy sebesar 1,5, rasio (B/C) untuk budidaya caisim sebesar 1,1 dan rasio (B/C) untuk budidaya kangkung  sebesar 1,4.

The Effect of Addition of Ca(NO3)2 to the Results of Lettuce (Lactuca sativa L.) in the Hydroponic System of Deep Flow Technique (DFT). Plants, in general, require composition, concentration, and volume of nutrient solutions which different depends on the type and phase of plant growth. Leaf vegetable crops such as lettuce (Lactuca sativa L.) require higher Nitrogen (N) nutrients than other vegetable crops, but the problem we faced at the moment is the hydroponic nutrients that are traded only in the general form of nutrient, therefore the addition of N nutrients in the form of calcium nitrate (Ca(NO3)2) needs to be done to meet the needs of lettuce plants. This study was aimed to determine the effect of the addition of Ca(NO3)2 and to find the optimum dosage of the addition of Ca(NO3)2 to the general hydroponic nutrition of vegetables on lettuce use DFT hydroponic system. The treatments consisted of five levels which are nutrition AB Mix general vegetable as a control, and nutrition AB Mix with the addition of 30 g, 60 g, 90 g, and 120 g Ca(NO3)2.  The results of the observation showed that the treatment of the addition of Ca(NO3)2 fertilizer had a very significant effect on all observed variables, except for the diameter of the lettuce plant. The optimum addition of Ca(NO3)2 for lettuce was found at 90.04 g with a maximum yield of 207.92 g.

Hydroponic Systems

Lettuce (Lactuca sativa L.) is one of the vegetables that are commonly cultivated by using hydroponic systems. Some hydroponic systems require high current expenses in particular for the electricity in order to circulate nutrient solution e.g. in the water culture system – deep flow technique (DFT) -. Electricity costs can be reduced by changing from continuous nutrient flow to intermittent nutrient flow. The aim of this research was to investigate the effect of interval nutrient flow on growth and yield of lettuce. The experiment was conducted in Cirebon from February to April 2018. The experiment was arranged by using randomized complete block design with four treatments: (i) continuous nutrient flow (control), intermittent nutrient flow (nutrient flow during (ii) 15 minutes, (iii) 30 minutes, and (iv) 45 minutes). For each intermittent treatment, the nutrient flow was interrupted for 60 minutes. Each treatment was repeated four times. The result showed nutrient flow interval affected to plant height, shoot diameter, and leaf area at 35 days after planting (DAP). Meanwhile, leaves number, root volume, and fresh weight of harvested crops were not significantly different in all nutrient interval treatments. The highest plant height and shoot diameter were detected in the treatment (ii) nutrient flow during 15 minutes and interruption for 60 minutes, the results were not significantly different to the control – continuous flow treatment. It can be concluded the interval nutrient flow can be used as an alternative of the continuous flow of nutrient solution in hydroponically DFT.

Maraknya pengalihan fungsi lahan pertanian menjadi pemukiman dan perindustrian di Indonesia cukup tinggi. Namun peningkatan pengalihan lahan pertanian tidak diikuti dengan penurunan kebutuhan pangan, dimana kebutuhan pangan terus meningkat setiap tahunnya. Hal ini mendorong suatu inovasi dalam bidang pertanian dengan mengubah pertanian konvensional menjadi pertanian modern guna efektifitas pertanian di lahan sempit. Salah satunya adalah dengan berhidroponik, yaitu budidaya menanam dengan memanfaatkan air tanpa menggunakan tanah dan menekankan pada pemenuhan kebutuhan nutrisi bagi tanaman. Namun, demi kemudahan proses budidaya di era digital ini, maka dilakukanlah penelitian untuk membuat sistem digitalisasi pada pertanian hidroponik yang terintegrasi dengan Internet of Things (IoT) menggunakan Iot MQTT Panel berbasis Andorid. Penelitian ini dilakukan melalui 4 tahapan yaitu studi pustaka, perancangan sistem, pembuatan sistem, dan pengujian sistem smart farming. Penelitian ini bertujuan untuk memudahkan pengontrolan jarak jauh dalam pertanian hidroponik dengan membuat sistem digitalisasi monitoring dan controlling menggunakan sebuah aplikasi tanpa si pemilik berada di lokasi hidroponik. Dalam penelitian ini digunakan Sensor pH, DHT11, Soil Moisture, dan Solenoid Valve untuk pemantauan serta pengelolaan nutrisi pada tanaman hidroponik khususnya pada tanaman cabai dan selada. Smart farming telah berhasil dibuat dan siap pakai untuk dapat memonitoring nutrisi, cahaya, suhu serta kelembapan pada tanaman hidroponik dan mengendalikan sirkulasi air pada tanaman hidroponik.
