Seaweed is macro algae that it one of export commodity at Indonesia. In addition to having economic value, macroalgae also have an important role in aquatic ecosystems. macroalgae play a role as primary producers because of their ability to photosynthesize, produce organic matter, and oxygen in the aquatic environment. Waters on Lombok Island that are overgrown with seaweed include Batu Layar beach. Batu Layar sub-district is part of the tourism area located in the coastal area. Batu Layar sub-district includes a cultivation area consisting of a variety of land uses ranging from agriculture, livestock, fishing and so on. This study aimed to analyze the diversity of seaweed species in the coastal waters of Batulayar, Senggigi, West Lombok Regency along with antioxidant and chlorophyll-a content. The research was conducted in November 2023 in the waters of Batu Layar, Senggigi, West Lombok Regency. The research methods used in this study were survey methods and method explanation of antioxidant content and chlorophyll was carried out in the laboratory, by taking random samples based on the boundaries of the predetermined area as many as 4 stations. The result of this research are identified species of seaweed including Sargassum sp., Padina, Caulerpa, Galaxaura, Ulva, Gelidium, Acanthophora, Iaxaura, Halimeda, Boergesenia forbesii, Corallina, and Turbinaria. Padina antioxidant levels reached 81,31% and chlorophyll 14,35 mg/l. It can be concluded that there are 12 types of seaweed that grow wild consisting of four species each of green, brown, and red alga. Padina has the highest antioxidant content of 81,31%.Keywords:AquacultureAntioxidantChlorophyllSeaweedSargassum.

Caulepa racemosa is a type of sea grape from the group of green algae (Chlorophyceae) that can be found in Indonesian waters. Coastal communities use this species as a source of daily food. Besides being a food ingredient, C. racemosa can be used for medical purposes because it contains antioxidants. The distribution of C. racemosa and its density in waters depends on the type of substrate and season. The substrate in the cultivation container is an essential factor in cultivating C. racemosa. Various substrates have different characteristics and influence the growth of C. racemosa. This research aims to analyze the best substrate for the survival of seaweed on a laboratory scale. This research used an experimental method using a Completely Randomized Design (CRD) consisting of 4 treatments, namely different substrates of sand, coral, volcanic rock, and coral sand. The results of this research are that different types of substrates have a real influence on the survival rate of C. racemosa cultivated on a laboratory scale. Sand substrate gave the best results: a survival rate of 112.83%, a final weight of 22.56 g, and the highest antioxidant content on volcanic rock substrate of 83.19%. This research concludes that differences in substrate directly influence the survival rate and final weight of C.racemosa. The substrate that provided the best survival rate of 112.83% was sand substrate.

Kuliah Kerja Nyata (KKN) is a real manifestation of lecturers and students in implementing Tri Dharma Perguruan Tinggi specially the aspect of service. Through community service activities on Pulau Maringkik Village, synergy can be established between the University of Mataram and the people of Maringkik Island as a form of knowledge democracy. The purpose of this service is to provide an understanding to the community about optimizing the promotion of Maringkik Island weaving through a website and based on digital marketing in order to help the government and the local community to develop UMKM to support the village's economy, as well as address socio-economic issues in the region. Methods of implementing activities include (1) preparation of advocacy and preparation of proposals, (2) planning includes the activities of designing a website prototype and making an activity roadmap, (3) the implementation stage of the website creation program, website launching, and technical guidance on website management, (4) monitoring is carried out to ensure the spread of the website Maringik Island woven fabrics in the community, and (5) An evaluation was carried out to see the number of website visitors and the number of sales during the presence of the website.
