Abstract

The intertidal zone of Iboih Beach in Sukakarya District, Sabang, has significant macroalgae diversity with different substrate variations. This study examined the diversity, distribution, and ecological significance of macroalgae using the quadrat method with purposive sampling technique on three plots measuring 2 2 m (coral, sand, and rock substrates), each replicated three times. Measurements of environmental parameters including temperature (using a thermometer), salinity (refractometer), and depth (Secchi disk) were carried out prior to sampling to ensure that environmental conditions were recorded. The results showed Galaxaura rugosa as the dominant species (INP 63.22), followed by Halimeda opuntia (38.42) and Chaetomorpha crassa (35.27), which showed a preference for hard substrates rich in nutrients. In contrast, Caulerpa sp. had the lowest INP (9.33), indicating specific habitat adaptation. The Shannon-Wiener diversity index (H=1.57) was in the moderate category, with an average INP of 28.575 reflecting a diverse community occupying different ecological niches. The coral substrate supported the highest abundance due to its stability and nutrient availability. This finding confirms the crucial role of substrate characteristics in the structure of intertidal macroalgal communities.Keywords:DiversityMacroalgaeIntertidal zoneSubstrateIboih Beach

Abstract

 A well-prepared community service activity introduces beneficial knowledge to the target community while contributing to students' scientific literacy. This activity aimed to train students at Pesantren Al-Manar, Aceh Besar, in making ecoprint as an alternative natural dyeing technique and to improve their scientific literacy. Ecoprint is a fabric-printing technique that transfers natural pigments from leaves and flowers onto cloth through direct contact, commonly applied using the pounding (hapazome) or steaming method. The activity was carried out for five days, from 26 to 30 May 2023, at Pesantren Modern Al-Manar, Lampermai Village, Aceh Besar, and involved 20 seventh-grade students of MTs Al-Manar. The methods used were lectures, demonstrations, group discussions, and presentations, in which students practiced applying leaves and flowers onto plain white fabric and tote bags. The results showed that the training ran smoothly and was well received, giving students new knowledge about ecoprint as an environmentally friendly, natural alternative to synthetic dyes, while also fostering their creativity and entrepreneurial spirit.
