Abstract

The cultivation and marketing assistance program for Siam oranges in Air Talas Village, Rambang Niru District, Muara Enim Regency, South Sumatra, aims to increase the production and marketing of Siam oranges and diversify the product range. This program involves training in the use of organic fertilizers, plant disease control, and the development of derivative products such as jam, pie, and orange syrup. Additionally, the program also includes innovation development through the use of the Trichoderma fungicide to address the current threat of Citrus Vein Phloem Degeneration (CVPD) disease. The program is expected to enhance farmers' income, strengthen the local economy, and empower the community of Air Talas Village.

Abstract

PT Pertamina EP Pendopo Field, within the GEMILANG (Movement for Women to Preserve Nature through Areca Nut Conservation) program, has successfully empowered the women of Sukakarya Village by promoting the cultivation and utilization of the abundant areca nut trees in the area. As beneficiaries of the GEMILANG program, the Melati Women's Farming Group (KWT Melati) has successfully produced health products from areca nuts, such as ginger areca nut tonic (bandrek) and areca nut juice. Since the program's inception in 2020, KWT Melati has become more productive, engaging in vegetable cultivation and organic fertilizer production using areca nut waste. As the program has grown, GEMILANG has become increasingly inclusive, involving more women from Sukakarya Village. New initiatives under GEMILANG now include the development of areca nuts as a corrosion inhibitor for the industrial sector, using areca nut waste in fabric production through eco-printing techniques, and exporting areca nuts.

Abstract

Water pollution from heavy metal contamination is a global issue; finding low-cost and sustainable solutions is challenging. Among various methods, biomass adsorption is a practical approach for treating heavy metal contamination in agricultural water. This study explored the use of betel nut peel as a biosorbent to remove Mg(II), Ca(II), and Fe(III) ions from agricultural water. The adsorbent contained active groups like −OH, C=O, and C=C, indicating cellulose, lignin, and hemicellulose compounds. Mature betel nut peels showed higher adsorption capacities than immature ones due to their larger surface area and more active sites. The optimal adsorption occurred at an initial adsorbate concentration of 100 mg L−1 for 1 h, with 5 mg of biosorbent. The biosorbent followed the Langmuir isotherm and a pseudo-second-order kinetic model (R2 = 0.99), indicating chemisorption. When applied to agricultural water from South Sumatra, the biosorbent removed up to 90% of Fe(III) ions. These findings suggest that betel nut peel powder has strong potential as a biosorbent for heavy metals, with promising applications in water treatment and environmental remediation. It also shows potential as a biofertilizer, particularly for soils rich in Fe(III).
