“…Hal ini disebabkan keadaan lingkungan menyebabkan suhu larutan nutrisi meningkat. Sumarni et al (2016) menyebutkan suhu tinggi pada daerah perakaran diikuti respirasi akar meningkat dan kecepatan pertumbuhan berkurang. Rata-rata panjang akar dan biomassa yang dihasilkan adalah 29,6-36,3 cm dan 4,41-5,06 g. Bagian akar yang terendam nutrisi berwarna coklat, berbeda dengan bagian atas yang tidak terendam.…”

<p style="text-align: justify;">Cauliflower has a high consumption level but its production is limited to its region in the highlands and the planting season. An effort to increase its production outside the highland in all seasons is using hydroponics on tolerant varieties. Selection of varieties and giving the right amounts of nutrients will optimize the production of lowland cauliflower. This study aims to determine the types of varieties and concentration of nutrient solution suitable for the cultivation of hydroponic cauliflower in the lowlands. This research uses a Completely Randomized Design (CRD) which consists of 2 factors namely varieties and nutrient solution concentration level with 9 combination treatments and each treatment consisted of 4 plants. The results showed that variety of Mona and PM 126 are better than the Diamond in the hydroponic cultivation of cauliflower in the lowlands. Concentrations of the nutrient solution did not improve growth and show no significant results, so nutrient solution from EC 2.2 to 2.4 mS/cm is better in the hydroponic cultivation of cauliflower in the lowlands.</p>

“…Teknik ini juga telah berhasil digunakan untuk produksi benih kentang dibeberapa negara di dunia (Otazu, 2010;Farran and Castel, 2008;Corea et al 2008). Penanaman kentang di dataran rendah tropika sebagai usaha mengurangi dampak buruk penanaman di dataran tinggi seperti erosi, hama dan penyakit tanaman juga telah dilakukan dan berhasil diperoleh umbi (Sumarni et al 2013abc;Sumarni et al 2016). Produksi benih kentang dengan sistem aeroponik dan modifikasi iklim di lingkungan perakaran (root zone cooling) pada ketinggian 250 m dpl diperoleh umbi 10-14 umbi/tanaman.…”

“…Namun ketika suhu udara yang akan diturunkan/dikehendaki terlalu rendah dan tidak dapat dilakukan dengan desain ventilasi maka dapat dilakukan dengan pengendalian mekanik. Pendinginan daerah perakaran dapat digunakan sebagai alternatif menurunkan suhu di daerah perakaran (Sumarni et al 2013a,b,c;2016).…”

“…Produksi benih kentang dengan sistem aeroponik aplikasi root zone cooling pada ketinggian < 125 m dpl diperoleh kurang dari 5 umbi/tanaman. Suhu udara yang dipertahankan di daerah perakaran untuk menghasilkan umbi pada teknik tersebut adalah 10°C (Sumarni et al 2013a;Sumarni et al 2016). Namun upaya mempertahankan suhu 10 °C di daerah perakaran pada sistem aeroponik memerlukan energi yang cukup besar dan dilakukan secara mekanik.…”

Planting potatoes in the tropical lowlands as an effort to reduce the adverse effects of planting in the highlands such as erosion, pests and plant diseases has been carried out and the tubers have been successfully obtained. Planting of potato seeds was carried out with an aeroponic system and climate modification in the root zone cooling environment. Climate modification is carried out at an altitude of 250 m asl and <125 m asl. The stability of the temperature in the aeroponic chamber can be maintained by regulating the time of spraying cold nutrients through the nozzles to the root area. However, the importance of the time to provide nutrition in order to maintain the optimal temperature of the root area in aeroponic systems in the lowlands has not been widely reported scientifically. The purpose of this study was to obtain the appropriate time for nutrition in order to maintain optimal chamber temperature and to have an effect on the growth and yield of potato seeds. The research was conducted in the greenhouse of the Faculty of Agriculture, Jenderal Soedirman University, Purwokerto, Central Java, Indonesia. Height of place <125 m above sea level. The study was conducted from July to September 2017. The factors that were tried in the study were as follows: 1. Length of time for nutrition (T): T1: 2.5 minutes OFF and 15 minutes ON; T2: 5 minutes OFF, 15 minutes ON, T3: 10 minutes OFF, 15 minutes ON, T4: 15 minutes OFF, 15 minutes ON, 2. Varieties (V): V1 (Atlantic), V2 (Granola). Growth parameters observed: plant height, number of leaves, number of tubers, tuber weight. Experiment using a randomized block design with 3 replications. The data were analyzed by F test and continued with Duncan’s Multiple Range Testof 5% level.The results showed that the duration of nutrient administration by setting a timer gave different results on the growth and development of aeroponic plants of potato seeds in the lowlands 125 m above sea level. The duration of nutrition administration 2.5 minutes OFF gave the highest number of tubers and tuber weight compared to the duration of nutrition 5 minutes, 10 minutes and 15 minutes OFF. The number of tubers obtained is 7.3 tubers / plant with boto an average of 2 mg. The duration of nutrition is 5 minutes, 10 minutes and 15 minutes OFF does not produce tubers.

“…Various studies to increase the G0 seed production have been undertaken (Dianawati et al, 2019;Dianawati et al, 2013;Sumarni et al, 2016;Waluyo & Karyadi, 2017). However, research regarding G0 seed production management conducted by the breeder / potato farmers in Indonesia is very limited.…”

The availability of Indonesian potato seed and production of potato for consumption depends on the availability and quality of Generation 0 (G0) potato seed. This study aims to observe G0 potato seed production management in Indonesia. Data were collected through Focus Group Discussion (FGD) and survey. Thirty-seven G0 potato seed producers participated in the survey. Data were analyzed descriptively, while the feasibility of the farm budget of G0 potato production was calculated using the enterprise budget method. The results showed that the producers had challenges on capital to broaden the screen house to extend the production scale and limited plantlet availability. Meanwhile, they did not have any problems with other production aspects, such as controlling pests and diseases and the marketing of the G0 seed. Government supports to provide screen houses to fulfil producers' necessity and delegate the legality of potato plantlets are needed to create a better Indonesia's potato seed system.
