Abstract

Sources of activity in Dorei Bay come from the Sanggeng market, the Wosi market, the port, the PLTD (Diesel Power Plant), hospitals, hotels, and residential areas. The seagrass system has a function as a food provider, as primary productivity in waters, dampers the arrival of waves, a place for growth and development of biota and sediment traps. Research and information on the accumulation of heavy metals in seagrass, especially Cymodocea rotundata are still very limited, especially in Doreri Bay. This study aims to describe the accumulation of heavy metals in seagrass Cymodocea rotundata, including leaves, roots, and rhizome, comparing the accumulation of heavy metals in seagrass Cymodocea rotundata each location as well as knowing the pollution index of each location. The research was conducted in Doreri Bay, Manokwari, West Papua in August 2018. The sampling locations for Cymodocea rotundata seagrass were around the waters of Pelayaran, Wosi, Yankarwar, Anggrem, and Nusmapi Island. The results showed that the highest Cu concentrations were described from each location, which ranged from 18.75 to 28.64 (mg.kg-1), followed by heavy metal Pb ranging from 0.46-19.31 (mg.kg-1), then logm weight of Cd ranged from 1.11-4.97 (mg.kg-1) and the lowest Cr6 + concentration in each location ranged from 0.20 -0.52 (mg.kg-1). The percentage of metal concentrations in the roots and rhizomes is 50%, it can even reach 82.64%, namely Pb metal at Yankarwar Beach. Meanwhile, the metal concentration in the leaf area ranged between 17.36-50.00% and the highest proportion was found in Pb metal at the Pelayaran location and Cr6 + metal at the Wosi location. The calculation results of the Metal poluttion Index (MPI) for heavy metals Pb, Cd, Cu, and Cr6 + show that the highest heavy metal index of 5 locations is on Anggrem Beach and the lowest is at Pelayaran Beach

Abstract

The potential area of Lombok seaweed cultivation is 5490 Ha. The area utilized is 2039.63 Ha. The purpose of this paper is to review the diversity, cultivation activities, production and potential of seaweed to be developed, specifically focusing on aspects of cultivation and production on the island of Lombok, Indonesia. Macroalgae that have been cultivated on Lombok are Kappaphycus alvarezii morphotype brown and green and Gracilaria verucosa. The decline and the amount of uncertainty in production were caused by several problems in seaweed cultivation, weather changes, limited capital for production and decreased quality of seaweed seeds. The species that have the potential to be developed are Sargassum aquifolium, Caulerpa sp., Ulva sp., Eucheuma spinosum, and Gelidium sp. Development Locations are located throughout the waters in the shape of a bay and are by the stipulated water utilization spatial plan. Developing seaweed aqua tourism and institutional arrangements related to seaweed production is necessary.

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, and 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

Arthrospira platensis culture requires macro and micronutrients. The nutrients needed by Arthrospira platensis according to Agustina and Herman (2021) are macronutrients consisting of nitrogen (N), phosphorus (P), potassium (K), sulfur (S), iron (Fe), magnesium (Mg), silicon (Si), and calcium (Ca). Micronutrients consist of zinc (Zn), cobalt (Co), molybdenum (Mo), boron (B), and copper (Cu). Rice-washing wastewater contains macro and micronutrients needed for the growth of Arthrospira platensis. Almost all of the nutrients needed by Arthrospira platensis are found in the wastewater, except for Co. Previous studies have shown that rice-washing wastewater can be used for Arthrospira platensis culture, but the growth rate is still higher than Walne fertilizer 0.5 ml/L. Zarrouk fertilizer as a standard growth medium for Arthrospira platensis shows that this fertilizer has better growth results than Urea and NPK fertilizers. This research was conducted to determine the effect of rice-washing wastewater as a nutrient source for culture media or a combination of Zarrouk fertilizer and rice-washing wastewater so that it can be used to increase the biomass and carotenoid pigments of Arthrospira platensis. This research used a Factorial Completely Randomized Design (CRD) with 12 treatments and 3 replications. Arthrospira platensis quality test was carried out by testing dry biomass and carotenoid content. The ANOVA test results showed that this study's treatment had a significant effect on the carotenoid content and biomass of Arthrospira platensis. The treatment with the highest effect of biomass and carotenoids was obtained in the treatment of 1.5 ml/L of rice-washing wastewater
