Abstract

Demand for salt in Indonesia continues to increase, while local production has not kept up and therefore relies on imports. Salt production faces challenges such as weather dependency and the risk of soil mixtures that degrade product quality. This community empowerment program aims to improve the quality and quantity of hygienic salt production in business groups through the application of geomembrane technology, and increase production capacity to meet standards. The program methods include socialization, technical training on geomembrane installation, assistance in production, and evaluation. The results and impacts of the salt production process increased by 20%, salt products produced are whiter, hygienic, and meet SNI standards. In addition, the income of the business group increased by 50%. This production has successfully improved productin efficiency and the welfare of salt farmers. In the future, the group plans to expand the market, improve infrastructure, and submit products for formal certification. Geomemran technology has proven to be an effective and sustainable solution in supporting hygienic salt production.

Abstract

Leachate is a liquid waste formed due to water seepage into waste piles containing high concentrations of organic and inorganic compounds that have the potential to pollute the environment. This study aims to evaluate the effectiveness of Azolla microphylla plants in reducing leachate pollutant parameters from the Blang Bintang TPA through the phytoremediation method. Variations of treatments include plant masses of 300 and 400 grams and residence times of 7 and 14 days. The parameters analyzed include Chemical Oxygen Demand (COD), Total Suspended Solid (TSS), and Biochemical Oxygen Demand (BOD). The results showed that the best treatment was obtained at a plant mass of 400 grams with a retention time of 14 days, with the effectiveness of reducing COD by 22.95% (from 758 mg/L to 584 mg/L), TSS by 60.80% (from 523 mg/L to 205 mg/L), and BOD by 22.40% (from 424 mg/L to 329 mg/L). Although it has not met the leachate quality standards based on Permen LHK No. 59 of 2016, the use of Azolla microphylla shows potential as an environmentally friendly phytoremediation agent. It can be further developed as part of a sustainable leachate treatment system.

Abstract

This study reports the synthesis and characterization of a monolithic activated carbon adsorbent modified with alumina and chitosan (Al-Chit/OAC), derived from oil palm empty fruit bunches (OPEFB). The adsorbent was fabricated through pyrolysis, followed by alumina incorporation and chitosan impregnation. FTIR analysis confirmed the presence of functional groups including OH stretching (3640cm), CH stretching (2920cm), CN/CO stretching (10551031cm), and AlO vibrations (693, 522, 495cm), indicating successful surface modification. TGA revealed two major stages of thermal degradation, with a total mass loss of 17.4% and a final residue of 17.55%, reflecting the presence of thermally stable inorganic components. SEM imaging showed a heterogeneous and porous surface with agglomerated particles and interparticle voids, suggesting enhanced surface accessibility. Even though we didn't test how well it absorbs substances, the physical and chemical properties of the composite show it could be very useful for cleaning up acid mine drainage (AMD) in the future. Further studies are recommended to validate its adsorption performance.
