Abstract

The increase of human population impact to more land needed for residence and has an impact on the decreasing land for agriculture, especially in urban areas. One of solution for farming in urban areas is by utilizing rooftop farming by hydroponic cultivation. The hydroponic system that used in this research is floating raft system. This study aims to determine the performance of the floating raft fertigation system which includes the amount of energy consumption, water, nutrient solution, growth uniformity and yield productivity in water spinach cultivation using floating raft fertigation system for one period of growth. This research was carried out on the rooftop of the building of the Food Industry Technology Department of Padjadjaran University with descriptive analysis method. The parameters measured in this study were the amount of water consumption, nutrition and electrical energy from the floating raft fertigation system that was used and uniformity of the results of plant growth including plant height, root length and plant weight at harvest determined in this study, 16 days after transplanting. Result showed that water consumption for one time growth period water spinach was 300,63 liters; consumption of nutrients was 3860 ml and electricity consumption was 31,816 kW. The uniformity of water spinach plant results of the study was in the category of good. The efficiency of water use was 99.6 kg/m3 and plant productivity based on research results is 72.8 kg/m2.

Abstract

Media tanam adalah salah satu faktor penting dalam budidaya tanam. Media tanam yang baik harus mampu memenuhi persyaratan karakteristik sebagai media tanam. Hidroton merupakan media tanam anorganik dari tanah liat yang dipanaskan. Tanah liat dalam menahan air dipengaruhi oleh tekstur tanah dan bahan organik. Penambahan bahan organik pada hidroton dapat mengubah karakteristik hidroton. Penelitian ini bertujuan untuk mengetahui pengaruh dan komposisi terbaik penambahan bahan organik berupa arang sekam, cocopeat dan kompos pada pembuatan hidroton terhadap karakteristik hidroton sebagai media tanam hidroponik. Percobaan disusun menggunakan Rancangan Acak Lengkap (RAL) dengan delapan perlakuan berupa kontrol dan penambahan masing-masing bahan organik dengan dosis sebesar 2,5% dan 5% sebanyak empat kali ulangan. Data dianalisis menggunakan ANOVA dan dilanjutkan dengan uji DMRT pada taraf 5%. Hasil penelitian menunjukkan bahwa penambahan bahan organik berpengaruh nyata terhadap nilai bobot isi, kadar air, tingkat kekerasan, water holding capacity (WHC), pH dan nilai EC hidroton. Perlakuan yang dianggap memberikan hasil terbaik terdapat pada perlakuan D5 (Cocopeat 5%) dengan nilai BD media 1,417 gr/cm3, kadar air 3,623%, kekerasan 38,001 N/cm2, WHC 37,453%, pH 6,175, dan EC 192,05 μS/cm.

Abstract

The hydroton planting media that is marketed has the characteristics of low water holding capacity. The addition of organic material in the form of husk charcoal, cocopeat, and compost clay can increase the water holding capacity of the hydroton so that plant productivity increases. This study aims to determine the composition of the best planting media for pakcoy plant growth in hydroponic floating raft systems. The research was carried out at the Rooftop of the Food Building of the Faculty of Agricultural Industrial Technology, Padjadjaran University. The experiment was arranged using a completely randomized design that was repeated four times and seven combinations of treatments. The composition of organic matter is added as much as 2.5% and 5% of each organic material. The variables observed were plant height, the number of leaves, root length, leaf area, wet weight, and stover weight. All data were analyzed using ANOVA followed by DMRT test at the level of 5%. The results showed that the organic matter in hydroton had a role in the parameters of growth and productivity of pakcoy plants compared to hydroton materials without comparing organic matter and the weight of root wet. The treatment of adding organic matter in the form of (husk charcoal, 5%) and (Cocopeat, 5%) is a treatment that affects the root length and weight of root wet.
