Abstract

Composite membranes consist of matrix and filler. The matrices used are C and CP. Meanwhile, the filler used is MMT-CNT. The aim of this research is to improve the properties and performance of composite membranes by reviewing the effect of adding montmorillonite particle filler as a matrix and MM-Carbon as a filler. The membrane was made using the phase inversion method and solvent evaporation. The physical characterization carried out was FTIR, XRD, and SEM. Meanwhile, for characterization of membrane performance, namely swelling, methanol uptake, ion exchange capacity, methanol permeability, proton conductivity, and TGA. The results of this characterization showed that the optimum membrane was found at C 1.96 - CP 0.09/ MMT-CNT. In this membrane, methanol permeability was found to be 2.64x10-6 cm2/s, proton conductivity was 3.352x10-6 S/cm, selectivity was 1.2714 Ss/cm3, and membrane stability at a temperature of 290°C. So the optimum composition is C 1.96 grams, CP 0.09 grams, and MMT-CNT 0.129 grams.

Abstract

This community service activity was carried out by the Chemistry Study Program of Tribuana Kalabahi University (UNTRIB) in collaboration with the Altar Youth Classis, with the aim of increasing the knowledge and skills of young people in utilizing local organic materials to make bokashi-type solid fertilizer. Alor Regency has abundant natural resource potential, but the still traditional agricultural system and dependence on inorganic fertilizers are major challenges. Through this activity, young people were trained to process organic materials such as goat manure, lamtoro leaves, banana stems and other organic materials as well as household waste with the help of effective microorganism fermentation (EM4) into environmentally friendly and economically valuable bokashi fertilizer. This activity included the delivery of materials, a question and answer session about fertilizer making, and direct mentoring by lecturers and students of the UNTRIB Chemistry Study Program. The results of this activity showed an increase in the participants' understanding and skills in the fermentation process, organic waste management, and the application of chemical principles in agricultural practices. Thus, this training is expected to encourage youth independence in the agricultural sector while strengthening collaboration between universities and the community in realizing sustainable agriculture based on local wisdom.
