Abstract

This community service program aimed to develop environmentally friendly pottery technology through collaboration between Universitas Mataram, Indonesia, and Dong Thap Community College, Vietnam. The activities were conducted in Penujak and Banyumulek Villages, Lombok, focusing on the application of composite technology using combustion ash waste and the utilization of natural dyes. The methods included socialization, focus group discussions (FGDs), and hands-on practice with local artisans. The results indicated a significant increase in participants’ knowledge regarding composite technology concepts, alternative material utilization, and combustion ash processing techniques, with an average improvement ranging from 45% to 70%. Furthermore, the practical application of natural dyes, such as sappan wood, tegeran, jolawe, indigosfera, meranti wood, and areca nut, was successfully demonstrated in pottery products. A satisfaction survey revealed that most participants were satisfied to highly satisfied with the training and were motivated to continue developing composite pottery with eco-friendly dyes. Overall, the program effectively enhanced artisans’ knowledge, skills, and motivation, while supporting the diversification of pottery products toward more innovative and globally market-oriented outcomes.

Abstract

Black cumin seed extract (Nigella sativa) is effective to control ASTM A36 steel corrosion in 1 M HCl solution. This study analyzed black cumin seed (BCS) extract as a corrosion inhibitor (0 to 500 ppm) by electrochemical method including Potentiodynamic Polarization (PDP) and Electrochemical Impedance Spectroscopy (EIS). The results revealed that with the PDP method the highest inhibition efficiency (IE) was 84.26% at the concentration of 500 ppm, and with the EIS method the IE value was 77.77% at the same concentration. The components of the extract were analyzed by GCMS and obtained major compounds are linoleic acid (22.12%), methyl linoleate (22.70%), 4-cyclopentene-1,3-dione,4-3-methyl-2-butenyl) (7.64%), methyl palmitate (6.66%), and palmitic acid (5.14%). A theoretical approach with computation was also carried out to investigate the performance and interaction of the major compounds in the BCS extract that a significant role as inhibitor. This was using Density Functional Theory (DFT) method and Monte Carlo simulation. The results showed that methyl linoleate compound as the most significant role.

Abstract

Experimental corrosion tests and theoretical calculation were conduct to investigate the corrosion inhibition mechanism of black cumin seed extract for copper in 1 M H2SO4 solution. Electrochemical testing using electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP) method showed that BCS adsorbed to form a protective layer on the copper surface with high inhibition efficiency at 500 ppm concentration (73,35%). Increasing the BCS concentration up to 500 ppm causes the charge transfer resistance increase in the EIS measurement, while the corrosion current density measured by PDP decreases. The values of charge transfer resistance and corrosion current density at 500 ppm BCS are respectively 3687 .cm2 and 2.86 μA.cm-2. The BCS is a mixed inhibitor (anodic and cathodic) that adsorbs physically on the copper surface and obey the Langmuir isothermal adsorption model. Quantum chemical calculation and molecular dynamic simulation show that the studied BCS molecules adsorb strongly on the copper surface with parallel orientation mode. The methyl linoleate (MLIN) molecules from BCS produce the most stable adsorption energy of the other studied compound molecules as a result of molecular dynamic simulation.

Abstract

This community development program was motivated by the large amount of broken pottery waste generated during the firing process that remains unutilized in the traditional pottery industry of Banyumulek Village. The clay waste has significant potential as an innovative additive in the production of natural soap. The purpose of this activity was to enhance community awareness and skills, particularly among members of KSL Rinjani Lombok, in processing waste into environmentally friendly and economically valuable products. The implementation methods included socialization and training. The socialization stage provided understanding of the potential of clay waste and opportunities for developing natural soap products, while the training stage was conducted through hands-on practice covering material preparation, mixing with soap base ingredients, and soap molding techniques. The results of the activity showed an increase in participants’ knowledge and skills in utilizing clay waste, with the highest improvement reaching 85%. Community partners were able to produce natural soap with good quality and market potential. In addition, the program successfully achieved its objectives by empowering the community through innovative utilization of pottery waste, while fostering the creation of competitive and eco-friendly product.

Abstract

Industri batik tradisional di Kampung Batik Giriloyo, Yogyakarta, tidak hanya berfungsi sebagai pusat warisan budaya tetapi juga sebagai penggerak vital perekonomian lokal. Namun, proses produksinya yang tradisional, terutama penggunaan lilin dan pewarna sintetis, berpotensi menimbulkan risiko lingkungan. Studi berbasis kegiatan masyarakat ini menyelidiki bagaimana limbah yang dihasilkan dari produksi batik dikelola dan mengevaluasi efektivitas serta dampak keberlanjutan dari praktik yang ada. Melalui international community service 2025, observasi lapangan dan wawancara semi-terstruktur dengan perajin batik dan tokoh masyarakat mengungkapkan bahwa Giriloyo telah membangun sistem pengolahan limbah lokal dengan prosedur operasi standar yang jelas. Meskipun tidak ada keluhan lingkungan yang signifikan dari masyarakat di sekitarnya, studi ini mengidentifikasi area-area kunci yang perlu ditingkatkan, terutama rendahnya efisiensi penggunaan kembali lilin (di bawah 10%) dan tidak adanya tahapan pengolahan pewarna yang berkelanjutan. Berlandaskan pada prinsip-prinsip kimia hijau, terutama pencegahan, bahan pengganti yang lebih aman, dan pengurangan limbah. Studi ini merekomendasikan peningkatan teknologi yang terjangkau dan kemitraan strategis untuk meningkatkan kinerja lingkungan. Temuan ini menawarkan model yang dapat direplikasi untuk industri kerajinan yang berakar pada budaya dan sadar lingkungan di pedesaan. Makalah ini berkontribusi pada wacana yang berkembang tentang ekonomi warisan berkelanjutan dan menyoroti potensi inovasi lokal dalam mencapai ketahanan ekonomi dan pengelolaan lingkungan.
