“…This is especially the case with the growth of plant roots, which has a great effect on the adsorption of various chemicals and DO, since the plant roots have an important function in reducing nitrogen and increasing DO. The roots form habitats for microbes, which cause nitrification/denitrification and also nutrient absorption in the hydroponic plant [ 47 ]. Thus, it can be expected that the level of ammonia, nitrite, and turbidity would be substantially lower in an efficient aquaponic system and an aquaponic system supplemented with activated carbon due to the continual uptake or adsorption and in filtering by the plant roots and activated carbon.…”

The effects of hydrothermal treatment, 0–5% KMnO4 content, and 300–400 °C pyrolysis temperature, were studied for activated carbon preparation from sugar cane leaves in comparison with non-hydrothermal treatment. The percent yield of activated carbon prepared by the hydrothermal method (20.33–36.23%) was higher than that prepared by the non-hydrothermal method (16.40–36.50%) and was higher with conditions employing the same content of KMnO4 (22.08–42.14%). The hydrothermal and pyrolysis temperatures have the effect of increasing the carbon content and aromatic nature of the synthesized activated carbons. In addition, KMnO4 utilization increased the O/C ratio and the content of C-O, Mn-OH, O-Mn-O, and Mn-O surface functional groups. KMnO4 also decreases zeta potential values throughout the pH range of 3 to 11 and the surface area and porosity of the pre-hydrothermal activated carbons. The use of the pre-hydrothermal activated carbon prepared with 3% KMnO4 and pyrolyzed at 350 °C as a filter in an aquaponic system could improve the quality of water with pH of 7.2–7.4, DO of 9.6–13.3 mg/L, and the turbidity of 2.35–2.90 NTU. It could also reduce the content of ammonia, nitrite, and phosphate with relative removal rates of 86.84%, 73.17%, and 53.33%, respectively. These results promoted a good growth of catfish and red oak lettuce.

“…The basic idea behind the operation of aquaponics is the simultaneous cultivation of aquaculture and plants, where both are mutually dependent on each other for survival (Paudel, 2020), with the relationship maintained by the efficient establishment of the nitrogen cycle. Our results indicate that the aquaponic environment encourages the accumulation of biomass, which is reflected in the higher weights of C. gariepinus raised in the system compared to those raised in the conventional pond.…”

Recirculating aquaponics integrate aquaculture and hydroponics with the aid of microorganisms to ensure a sustainable supply of fish and vegetables. In this study, we designed and constructed a flood-and-drain aquaponic system with Clarias gariepinus as the aquaculture and Celosia argentea, Corchorus olitorius, and Ocimum gratissimum as plant components. Nitrogenous waste from the aquaculture unit was circulated to the plant growth beds, which served as bio-oxidizers of toxic ammonia to nitrate and returned less toxic water back to the aquaculture unit. An evaluation of the growth parameters of C. gariepinus in aquaponics and control fish tanks revealed that aquaponics-raised C. gariepinus gained an additional 205.6% of their initial mean weight, whereas those grown in the control fish tank gained an additional 182.2% of their initial mean weight. The majority (37.5%) of aquaponics-raised C. gariepinus weighed 750 g -1 kg, whereas the highest percentage of C. gariepinus raised in the control fish tank (23.4%) weighed 500 g -700 g. C. gariepinus raised in aquaponics had significantly higher gross feed conversion efficiency and protein efficiency ratio than those raised in the control tank. The mortality rate in the aquaponic fish tank was 0% compared to the 11.43% mortality rate in the control fish tank. There was no significant difference in the nutritional composition of C. gariepinus raised in either tank; however, the aquaponic fish tank had a higher nitrogen retention rate. This study showed that C. gariepinus raised in aquaponics had better biomass accumulation than those raised in conventional fishponds.

“…An organic crop is produced by the recirculating system in aquaponics and preventing nitrogen losses via infiltration and surface leaching, which are the main problem for nitrogen losses in soilbased agriculture [11]. Aquaponics also engaged in measuring the polymerase chain reactions and next-generation sequencing to analyze the bacterial communities and their links to transform nitrogen [12]. There is also research where people are more willing to pay similarly for both aquaponics and soil-grown lettuce with some amount of money [13].…”

This research presents project development on smart farm and agriculture. The surge in global population is compelling a shift towards smart farm and agriculture practices. This coupled with the diminishing natural resources increase in unpredictable weather conditions makes food security a major concern for most countries. As a result, the use of the internet of things (IoT) and data analytics (DA) are employed to enhance the operational efficiency and productivity in the farm and agriculture sector. The objective is to design a prototype that used the internet of things on the farm and agriculture. Next is to have a monitoring and controlling or automation system that will benefit the farmer. Then collect all the data to be analyses on the rainfall, temperature, humidity, and light intensity. The methodology comprised of hardware, software, programming, sensors such as water sensor, light depending resistor sensor, temperature, and humidity sensor, and weight sensor for collected data. The result presents a prototype on aquaponics and goat stall that implement the concepts of the internet of things for monitoring, controlling, or automation system while data analytics is presented from all the sensors. Analytic data on the temperature, light intensity, humidity, and rainfall rate are analyzed. Surrounding temperatures are important for both plants and fish because if it too hot, they can die easily. The optimum light is needed by the plant for their photosynthesis process. Thus, by monitoring and collecting these parameters, data can be used for analyzing purposes. This project can benefit the agriculture and farm sectors in a larger or small scale.
