Abstract

Hydroponic model SWU-01 is a new hydroponic system innovation that regulates watering automatically and independently by utilizing gravity and Archimedes' law. Dissolved oxygen concentration in SWU-01 is only around 3-4.2 mg/L. DO values can be increased by applying nanobubble technology. Ultrafine bubble or nanobubble is a gas bubble in a liquid that has a diameter of <200 nm. The purpose of this study was to determine the effect of nanobubble on dissolved oxygen concentration and growth of lettuce plants cultivated with SWU-01 hydroponics. The experiment used a one-factor randomized complete block design, namely intermittent administration of nanobubble for 15 min every 3 day (P1) and 7 days (P2), and without nanobubble (P0l). The results obtained based on the ANOVA test at the 5% level with the Least Significant Difference (LSD) follow-up test, namely the parameters of fresh weight and number of leaves of lettuce P1 significantly different from P0 and P2, and no significant differences were found in root length, canopy width, and plant height. The P1 treatment is more effective in increasing dissolved oxygen concentration, leaf count, and fresh weight of lettuce produced in lettuce cultivation using the SWU-01 hydroponic system. Keywords: Dissolved oxygen, Hydroponics, Lettuce, Nanobubbles, Plant growth.

Abstract

This study examines the high rate of poverty in Indonesia, particularly among Muslims, which is often associated with a misconceived understanding of simplicity in Islamic teachings. Simplicity is frequently interpreted as passive acceptance of deprivation and even regarded as a sign of piety, reinforcing structural poverty and social injustice. This research aims to deconstruct and reconstruct the Qur’anic concept of simplicity by emphasizing a liberative interpretation that promotes social justice rather than resignation. The study employs a qualitative approach through discourse analysis and thematic interpretation. It focuses on Qur’anic verses related to poverty and simplicity, while analyzing the social discourse shaped by their interpretations. This research is a library study, drawing on primary sources such as the Qur’an and classical as well as contemporary tafsir works, alongside relevant scholarly references. The theoretical framework combines Al-Farmawi’s thematic tafsir method and Anthony Giddens’ structuration theory to explain how individuals can critically engage with and transform oppressive social structures through reflexive action. The findings from QS. Al-Furqan: 67, QS. Al-A’raf: 29, and QS. An-Nisa: 79 indicate that simplicity in Islam is closely related to justice, self-restraint, and social responsibility in controlling consumerism. These results demonstrate that Islam does not legitimize poverty but calls for justice and resistance against oppressive structures.
