Abstract

Hydroton is a clay-based growing medium used in hydroponic systems with variations in size 1-2.5 cm. In Indonesia, most hydrotons are still imported from other countries. The main purpose of this study was to observe the root growth and production of tomato plants grown on hydroponic systems, static aerated technique (SAT) with variations in hydroton size. This study was designed using a complete random design (CRD) with 4 hydroton size treatments (commercial hydroton as control (H0) and 3 experimental treatment with differences in hydroton size made from a mixture of clay and charcoal husk burn (H1, H2 and H3) and 6 replications in each size treatment so that there are 24 experimental units. On the observation of plant productivity showed different results on the treatment applied, while on the growth of roots did not show different results but the growth of roots on artificial hydroton better than commercial hydroton as a control based on physical roots and trend data. The amount of fruit harvested per plant obtained the best results of 25 fruits in the H3 treatment and the total weight of fruit per plant obtained the best results of 1.055,5 grams in the H3 treatment. The longest root in this study measured 96.6 cm in H0 treatment and the weight of the heaviest root in the net pot is 71,5 grams in H1 treatment while the weight of the heaviest root outside the net pot is 276,6 grams in H2 treatment. Based on the results of this study, the increase in the size of the hydroton is able to increase the production value of tomato plants compared to commercial hydroton and hydroton which are smaller in size.

Abstract

This study aims to design, manufacture, and test a drum-type tilapia smoker (Oreochromis niloticus) with smoking material in the form of coconut shell with a tool capacity of > 8 kg, which is easy to move, shorter smoking time and can save fuel as much as 50%. during the curing process. This study uses the method of design, assembly or manufacture of tools, testing the results of the design, observation, and data analysis. Tilapia smoker (Oreochromis niloticus) drum type consists of several parts, namely smoking tube, exhaust funnel and thermometer, upper and lower doors, wheels, clamp hook, tube handle, fish clamp. This smoker can make smoked tilapia in less than 4 hours with coconut shell fuel, the capacity of the tool is > 8 kg. This tool smokes fish weighing 1.441 kg and consumes fuel, namely coconut shells weighing 2.9 kg. Theoretically, this tool can save energy by 67%, compared to traditional tools and 39.1% more efficient than similar tools, namely the cabinet system.
