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.

Abstract

Bugel Village has great potential for rice farming; however, the low level of mechanization in the harvesting process results in reduced efficiency and productivity, as most farmers still harvest rice manually. This program aimed to introduce and train farmers in the use of a paddy mower, which offers advantages in mobility, labor reduction, and time efficiency. This community service activity was carried out in January 2025 in Bugel Village, Tomo District, Sumedang Regency, West Java, where rice cultivation serves as the primary economic activity. The training was conducted through socialization and hands-on practice with 30 farmers as participants, resulting in increased knowledge and skills. Evaluation results showed a significant improvement in understanding and motivation to adopt this technology, with the paddy mower achieving a 12.09% higher work speed compared to manual processes. Overall, the activity received positive responses from farmers, who acknowledged the benefits of mechanization in enhancing work efficiency and the quality of rice harvesting.Desa Bugel memiliki potensi yang besar dalam pertanian padi, namun rendahnya tingkat mekanisasi dalam proses panen menyebabkan efisiensi dan produktivitas rendah. Hal ini disebabkan karena sebagian besar petani masih memanen padi secara manual. Kegiatan ini bertujuan untuk mengenalkan dan melatih petani dalam penggunaan mesin pemanen padi paddy mower, yang menawarkan keuntungan dalam mobilitas, pengurangan tenaga kerja, dan efisiensi waktu. Kegiatan pengabdian masyarakat ini dilaksanakan pada bulan Januari 2025 di Desa Bugel, Kecamatan Tomo, Kabupaten Sumedang, Jawa Barat, yang mempunyai mata pencaharian utama menanam padi sebagai aktivitas ekonomi utama. Pelatihan dilakukan dengan sosialisasi dan praktik langsung, yang menghasilkan peningkatan pengetahuan dan keterampilan yang dihadiri oleh 30 petani. Hasil evaluasi menunjukkan peningkatan signifikan dalam pemahaman dan motivasi untuk mengadopsi teknologi ini, dimana mesin paddy mower mempunyai kecepatan kerja lebih tinggi 12.09% dibandingkan dengan proses manual. Kegiatan ini mendapatkan respon positif dari petani, setelah terlihat manfaat mekanisasi dalam meningkatkan efisiensi kerja dan kualitas panen padi.
