Abstract

Kappaphycus alvarezii is used in industry as a food ingredient, a source of hydrocolloids, cosmetics, food additives, animal feed, fertilizers, biofuels, and medicinal ingredients. K.alvarezii is cultivated in several areas in Indonesia, including on the island of Lombok. The production of K.alvarezii is related to its growth and it is related to its phytohormones. K.alvarezii cultivated in Lombok is currently not known for its composition and amount of phytohormones. The content of phytohormones at different planting ages is of course different. The purpose of this study was to determine the number of phytohormones in seaweed K. alvarezii at different planting ages. This study was conducted in Ekas Bay, Lombok, Nusa Tenggara Barat from June to December 2020. The study used experimental methods and descriptive data analysis. The results of this study explain that currently cultivated K. alvarezii contains cytokinins, auxins, and gibberellins. Cytokinins obtained on the 9th day of planting were 11.62 ppm and increased on the 18th day to 12.34 ppm. At the next planting age, it continued to decrease on the 27th day to 11.43 ppm and at harvest time, the 45th day of 10.69 ppm. Auxin detected in the seeds used was 644.93 ppm, on the 27th day of 14.27 ppm, on the 36th day of 1078.25 ppm. Giberilin was detected on the 9th day at 0.49 ppm. This study concluded that K. alvarezii at different planting ages had different phytohormones content.

Abstract

Kappaphycus alvarezii is an important red algae and can be used as one of the primary raw materials in fisheries. It is widely cultivated because of its relatively cheap production technology, and post-harvest handling is simple and easy. This algae has excellent economic value for carrageenan producers. Carrageenan is used as a food ingredient, cosmetics, and medicine. The success of cultivating K. alvarezii seaweed can be achieved if a suitable environment for its growth supports it. One of the environmental aspects that influence the growth of K. alvarezii seaweed is the bottom substrate of the waters. This research aims to analyze the best substrate for cultivating green K.alvarezii seaweed on a laboratory scale. This research used an experimental method with a Completely Randomized Design (CRD) consisting of 4 treatments and three repetitions, resulting in 12 experimental units. The treatments tested were different substrates: a coral substrate, a sand substrate, a volcanic rock substrate, and a coral sand substrate. The results of this study showed that the average survival rate in various substrate treatments ranged from 7.16% to 39%, final weight ranged from 1.43 g to 7.8 g, specific loss rate ranged from -3.157%/day to -5.124%/day, carrageenan yield ranged from 6.8% to 18.4%, and thallus tissue showed that all treatments still showed the presence of cortex and medullary tissue with varying shapes and structures

Abstract

Gerupuk Hamlet, which is 100 m from the sea, is at great risk of natural disasters, especially tsunamis. Therefore, the Gerupuk Hamlet community's understanding of inclusive disaster mitigation is a necessity. Therefore, the Sengkol II Village KKN Team and TSBD conducted outreach regarding disaster recognition, prevention, disaster mitigation (evacuation routes and safe points), and disaster preparedness. This socialization was carried out with the aim of increasing the knowledge and understanding of the Gerupuk Hamlet community regarding disaster mitigation so that the community becomes more responsive to the disaster risks they face. The socialization method used is presentation of material and practice of making evacuation route maps along with disaster safe points. The socialization was considered successful because the participants who attended exceeded the target, namely 37 people. Apart from that, the people of Gerupuk Hamlet are increasingly aware of disaster mitigation through the outreach carried out. This is proven by the community's ability to create maps of evacuation routes and disaster safe points after presenting the material.

Abstract

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.
