Abstract

The greenhouse plays a pivotal role in creating an ideal environment for hydroponic cultivation. The greenhouse has utilized rainwater and basin water as a source of raw water for hydroponic farming. Presently, the water quality of Leuwi Padjadjaran basin fails to meet the standards required for hydroponics due to its turbidity, sediment content, discoloration, pH levels exceeding 7, and low dissolved oxygen (DO) concentration of 2.2 mg/l. The micro/nanobubbles (MNBs) technology stands as a viable method for water treatment owing to its capacity to bind impurities via radical OH. The application of MNBs for the treatment of basin water involves the use of a hydrodynamic cavitation MNBs generator with a dual-chamber rotating flow nozzle. The parameters evaluated in this research encompass DO concentration, MNBs stability, microbubble size, and the visual response to MNBs application. MNBs treatment was conducted with three different gases: air, oxygen, and ozone. Microbubbles were measured using the particle image velocimetry (PIV) method. The DO concentration reaches 21.6 mg/l when employing oxygen-based MNBs. On the third day post-generation, MNBs stability still maintains DO concentrations above the initial levels. Thus it can be used as hydroponic raw water.  Keywords:  DO concentration, Greenhouse, Micro/nanobubbles, Water treatment.

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

Improving the quality of wastewater and river water is a critical priority for environmental conservation. Vetiver root wastewater and water from the Citepus River in the Cikamiri sub-watershed, Garut Regency, have the potential to cause pollution that affects water quality and local ecosystems. This study evaluated different gases (air, oxygen, and ozone) during the application of nanobubble technology to improve the quality of vetiver root wastewater and Citepus River water in the Cikamiri sub-watershed. Parameters measured were DO, pH, and TDS before and during 15-minute nanobubble treatment. Results showed that oxygen and ozone gases significantly increased DO content of the wastewater and river water. In addition, ozone gas improved pH in river water, and decreased TDS most effectively with ozone. It was concluded that nanobubble technology has potential for enhancing wastewater treatment and river conservation.

Abstract

Produk samping dari proses penyulingan minyak atsiri berupa aerosol sering kali tidak dimanfaatkan secara optimal dan bahkan dapat menimbulkan dampak negatif terhadap lingkungan. Penelitian ini bertujuan untuk mengembangkan dan menerapkan teknologi nanobubble sebagai metode alternatif dalam memisahkan minyak atsiri dari aerosol, serta mengurangi beban limbah biologis, kimia, dan fisik. Nanobubble dihasilkan melalui generator tipe nosel aliran berputar berbasis kavitasi hidrodinamik, menggunakan berbagai jenis gas (udara, oksigen, dan ozon). Karakterisasi dilakukan dengan mengukur konsentrasi oksigen terlarut, pH, konduktivitas, dan ukuran gelembung mikro. Hasil menunjukkan bahwa generator yang dikembangkan mampu menghasilkan nanobubble dengan ukuran rata-rata gelembung mikro 18,85 μm, serta meningkatkan efisiensi pemisahan minyak atsiri dalam aerosol serai wangi. Nanobubble ozon dan oksigen menunjukkan performa yang lebih baik dibandingkan udara biasa dalam meningkatkan konsentrasi oksigen terlarut dan perubahan parameter fisik-kimia lainnya. Teknologi ini berpotensi untuk diterapkan dalam pengolahan limbah industri minyak atsiri secara berkelanjutan.
