“…Kualitas air menentukan dalam pembuatan nutrisi. Menurut Eikbuikwem et al (2020) bahwa kekurangan nutrisi dan ketidakseimbangan dalam perlakuan sirkulasi air berkontribusi pada perkembangan yang buruk untuk aliran air tanaman. Nilai ppm air yang baik untuk larutan nutrisi yang terbentuk berada di atas 800 ppm.…”

The purpose of this activity is to provide knowledge and skills for prospective entrepreneurs affected by the Covid-19 Pandemic in qualified hydroponic cultivation techniques. The method of implementing the activity is in the form of indoor training on the concepts and techniques of hydroponic cultivation. In addition, outdoor technical guidance is also carried out regarding the construction of hydroponic installations and cultivation practices, starting from making nutrition, sowing seeds, planting to harvesting. The method of field visits to successful hydroponic entrepreneurs is also carried out. Participants can properly follow the training materials and technical guidance on assembling installations and practicing hydroponic cultivation. The benefits and level of satisfaction of participants in participating in this activity reached a score of 8.75. This activity increases the interest of the training participants for hydroponic entrepreneurship. The condition of the harvested plants has not yielded the expected results, with yields still around 50% of the achievable potential. To ensure the sustainability of the activity and have a wider impact, the Konda Village Party should facilitate so that the participants of this activity can become tutors for other people who want to do hydroponic entrepreneurship.

“…In addition, it is the first paper (at the national and international level) which tries to ascertain the impacts of the reuse of graywater on income and sustainability of agricultural production for family farmers. Previous research usually addressed the reuse of water for irrigation in three main approaches: i) risk factors (biological, chemical, sanitary, soil salinization, eutrophication) (Toze, 2006;Moretti et al, 2019;Egbuikwem, Mierzwa and Saroj , 2020), ii) technical aspects (Dolar et al, 2019;Rizzo et al, 2019), and iii) regulations (Helmecke, Fries and Schulte, 2020;Mukherjee and Jensen, 2020). Ricart and Rico (2019) draw attention to the role of social scientists in the elaboration of studies capable of offering subsidies to decisions makers in the elaboration of strategies which may provide sustainability of agricultural production and an increase in the income of family farmers.…”

The semi-arid region of Ceará is a Brazilian area that is exposed to long and frequent periods of drought. Water scarcity is a threat to the population’s well-being and agricultural activities. We evaluated the effects of graywater reuse for agriculture on income and sustainability of agricultural production in the municipality of Iguatu, located in the semiarid region of the state of Ceará. It is an important research because it deals with a strategy that aims to reduce farmers’ vulnerability to the lack of water. There are no studies that assess the impacts of water reuse in the region. The propensity score matching technique was applied, and primary data were obtained by interviewing beneficiaries (treated group) and non-beneficiaries (control group). The results showed that the program has effects on sustainable agricultural production of small farmers because of the use of non-aggressive agricultural practices. In the group of beneficiaries, the income is 21.9% higher than of that in the group of non-beneficiaries. In addition, families that adopt water reuse have 26.8% higher levels of sustainability than those that do not adopt this strategy of living with drought.

“…The energy and chemical requirements of AOPs are high. Moreover, textile wastewaters are brackish wastewater and a desalination process is required for reuse [12,13]. Membrane processes such as reverse osmosis (RO) and electrodialysis (ED) are the only known practical desalination methods to reuse textile wastewater.…”

Desalination and Detoxification of Textile Wastewater by Novel Photocatalytic Electrolysis Membrane Reactor for Ecosafe Hydroponic Farming

et al. 2021

In this study, a novel photoelectrocatalytic membrane (PECM) reactor was tested as an option for the desalination, disinfection, and detoxification of biologically treated textile wastewater (BTTWW), with the aim to reuse it in hydroponic farming. The anionic ion exchange (IEX) process was used before PECM treatment to remove toxic residual dyes. The toxicity evaluation for every effluent was carried out using the Vibrio fischeri, Microtox® test protocol. The disinfection effect of the PECM reactor was studied against E. coli. After PECM treatment, the 78.7% toxicity level of the BTTWW was reduced to 14.6%. However, photocatalytic desalination during treatment was found to be slow (2.5 mg L−1 min−1 at 1 V potential). The reactor demonstrated approximately 52% COD and 63% TOC removal efficiency. The effects of wastewater reuse on hydroponic production were comparatively investigated by following the growth of the lettuce plant. A detrimental effect was observed on the lettuce plant by the reuse of BTTWW, while no negative impact was reported using the PECM treated textile wastewater. In addition, all macro/micronutrient elements in the PECM treated textile wastewater were recovered by hydroponic farming, and the PECM treatment may be an eco-safe wastewater reuse method for crop irrigation.
