Abstract

Carotenoids are pigments with a range of red, orange and yellow colors. In carotenoid and chlorophyll plants are located in chloroplasts which undergo photosynthesis as well as photosynthetic bacteria and fungi. Carotenoid compounds have antioxidant activity, anticancer, as precursors of vitamin A and can enhance immunity. Crustaceans like crabs Grapsus sp. have carotenoid pigments, visible red, orange, and yellow are scattered in the carapace. Pigments found in crustaceans as well as crabs of Grapsus sp. generally sourced from food eaten by the crab. To determine the process of carotenoid pigment metabolism, each crab organ of Grapsus sp. isolated using thin layer chromatography separation method and column chromatography to determine the type of pigment contained therein. Pigment types identified in the crabs of Grapsus sp. males using the TLC method: β-carotene, Astasen type, Cantasantin, Astasantin, and Adonirubin. Pigment types identified in the crabs of Grapsus sp. males using the CC method: β-carotene, Astasen, β-cryptosanthine, Zeaxantine, and Cryptosanthine. Keywords : Grapsus sp., Thin Layer Chromatography, Column Chromatography, Carotenoids Pigments.             Karotenoid merupakan pigmen dengan kisaran warna merah, orange dan kuning. Pada tumbuhan karotenoid dan klorofil terletak pada kloroplas yang mengalami proses fotosintesis seperti juga pada bakteri fotosintetik dan fungi. Senyawa karotenoid memiliki aktivitas antioksidan, antikanker, sebagai prekursor vitamin A dan dapat meningkatkan imunitas. Krustasea seperti kepiting Grapsus sp. mempunyai pigmen karotenoid, terlihat warna merah, jingga, dan kuning yang tersebar pada karapas. Pigmen yang terdapat pada krustasea demikian juga pada kepiting Grapsus sp. umumnya bersumber dari makanan yang dimakan oleh kepiting tersebut. Untuk mengetahui proses metabolisme pigmen karotenoid maka masing-masing organ kepiting Grapsus sp. diisolasi dengan menggunakan metode pemisahan kromatografi lapis tipis dan kromatografi kolom untuk mengetahui jenis pigmen yang terkandung didalamnya. Jenis pigmen yang teridentifikasi pada kepiting Grapsus sp. jantan dengan metode KLT yaitu : β- karoten, Tipe Astasen, Kantasantin, Astasantin, dan Adonirubin. Jenis pigmen yang teridentifikasi pada kepiting Grapsus sp. jantan dengan metode KK  yaitu : β- karoten, Astasen, β-kriptosantin, Zeaxantin, dan Kriptosantin. Kata Kunci : Grapsus sp., Kromatografi Lapis Tipis, Kromatografi Kolom, Pigmen Karotenoid.

Abstract

Heavy metal is a very dangerous pollutant waste for it cannot be destroyed (non-degradable) and over time it will accumulate in the ocean. This study aims to determine the lead content in sediment, water and algal thallus as well as to determine the algae growth that has been treated with lead. The research method used was a completely randomized design (CRD) which consisted of 3 treatments, using different treatments for each sample. The highest metal content obtained in the sediment was 5,124 ppm, in the water was 0.120 ppm, and in the algae thallus was 4,816 ppm respectively. The results showed that Halimeda opuntia algae can grow even in an environment contaminated with lead heavy metal and can become a bioremediation agent by absorbing lead heavy metal. Keywords: Halimeda opuntia, Lead Heavy Metal, Algae Culture, Bioremediation             Logam berat merupakan salah satu limbah pencemar yang sangat berbahaya karena tidak dapat dihancurkan (non degradable) dan dapat terakumulasi di perairan laut. Penelitian ini bertujuan untuk mengetahui kandungan timbal pada sedimen, air dan thallus alga yang dikultur serta mengetahui pertumbuhan alga yang telah diberi perlakuan timbal. Metode penelitian mengunakan metode Rancangan Acak Lengkap (RAL) yang terdiri dari 3 perlakuan, dengan menggunakan perlakuan yang berbeda pada tiap sampel dan kontrol. Kandungan logam tertinggi yang didapatkan pada sedimen yaitu sebesar 5,124 ppm, pada air sebesar 0,120 ppm, dan pada thallus alga sebesar 4,816 ppm. Hasil yang diperoleh yaitu alga Halimeda opuntia dapat bertumbuh walaupun dalam lingkungan yang tercemar logam berat timbal serta mampu menjadi agen bioremediasi dengan menyerap logam berat timbal. Kata kunci: Halimeda opuntia, Logam BeratTimbal, Kultur Alga, Bioremediasi

Abstract

Microalgae are organisms that contain chlorophyll and other pigments so they can carry out photosynthesis. Microalgae are widespread in nature and can be found in any environment exposed to sunlight. Microalgae are micro-sized biota with a diameter of less than 2 µm. The benefits of microalgae for other living things, especially humans, are numerous, including as a source of food and ingredients in the manufacture of medicines. Dunaliella sp. is a group of green algae that contains protein, fat and carbohydrates as a good source of food. Growth rate and density of microalgae Dunaliella sp. and the effect of lead acetate with different concentrations was observed using a microscope, starting from the lag phase, the logarithmic phase, the stationary phase and the declination phase. Dunaliella sp. Experiencing an exponential phase in the observation before treatment, namely on the 9th day and then doing the treatment. Treatment with lead acetate with concentrations of 10 ppm, 50 ppm and 80 ppm is very influential in the growth of microalgae. The result is that lead acetate contains toxins that can kill microalgae cells in both low and high concentrations.Keywords: Microalgae, Dunaliella sp., Lead Acetate, Concentration

Abstract

Kappaphycus alvarezii is one species algae that is very widely developed in the tropical waters, especially in Indonesia. The potential in these waters may decrease due to heavy metal pollution that accumulates in algae and sediments. Analyzing the content of heavy metal arsenic (As), using the SNI 01-2896-1998 test method, namely the metal contamination test method in food. The results obtained from this study were samples of brown and green Kapapphycus alvarezii taken from week I-V detected containing heavy metal arsenic (As) ranging from 0.17 - 0.42 ppm for green algae and 0.12 - 0.37 ppm for brown algae. This As concentration does not exceed the maximum heavy metal limit, which is 1.0 ppm for the maximum limit for heavy metal contamination in food. The concentration of heavy metal in sediments is 1.12 ppm, not exceeding the quality standard in the Environmental Protection Agency (EPA), the maximum heavy metal limit for arsenic in sediment is below 10 mg/kg
