"Kanker paru merupakan salah satu kanker yang memiliki angka mortalitas yang tinggi di Indonesia. Sargassum polycystum merupakan salah satu spesies rumput laut yang banyak ditemui di perairan laut Indonesia dan memiliki potensi sebagai agen antikanker namun belum banyak diteliti. Penelitian ini bertujuan untuk mengetahui kandungan metabolit sekunder dan aktivitas sitotoksik dari ekstrak Sargassum polycystum terhadap sel kanker paru A-549. Sargassum polycystum diekstraksi menggunakan empat jenis pelarut, sehingga menghasilkan empat jenis ekstrak Sargassum polycystum, yaitu ekstrak n-heksana, ekstrak etil asetat, ekstrak kloroform, dan ekstrak etanol. Uji fitokimia pada keempat ekstrak Sargassum polycystum menunjukkan metabolit sekunder berupa flavonoid, tannin, glikosida, alkaloid, triterpenoid, dan steroid. Pada uji KLT menunjukkan bahwa ekstrak Sargassum polycystum memiliki tiga hingga empat senyawa kimia. Uji in vitro aktivitas sitotoksik keempat ekstrak Sargassum polycystum terhadap sel kanker paru A549 menggunakan metode MTT assay pada panjang gelombang 492 nm dengan 5 variasi konsentrasi, yaitu 3,125 g/mL; 6,25 g/mL; 12,5 g/mL; 25 g/mL; dan 50 g/mL. Data yang diperoleh dianalisis dengan menggunakan microsoft excel sehingga diperoleh nilai IC50. Berdasarkan nilai IC50 yang diperoleh, semua ekstrak memiliki nilai IC500,05. Hal ini menunjukkan ekstrak n-heksana memiliki aktivitas sitotoksik paling kuat terhadap sel kanker paru A-549 dibandingkan ekstrak lainnya, sehingga ekstrak n-heksana Sargassum polycystum berpotensi dikembangkan sebagai agen antikanker paru.

Lung cancer is one of cancer that has high mortality rate in Indonesia. Sargassum polycystum is one of macroalgae species that commonly found in Indonesian marine and can be developed as anticancer agent but has not been widely studied. Objective of this research is to know second metabolites compounds and cytotoxic activity of extract Sargassum polycyctum on A 549 lung cancer cell. Sargassum polycystum was extracted using four solvent to produce four extract, there are n hexane extract, ethyl acetate extract, chloroform extract, and ethanol extract.

Penelitian ini telah dilakukan pada bulan Maret--Mei 2018, dengan tujuanuntuk mengetahui seberapa besar perbedaan potensi penyerapan dan penyimpanankarbon pada makroalga Gracilaria verrucosa dan Halimeda opuntia di MuaraBinuangeun, Banten. Hasil penelitian yang didapatkan yaitu rata-rata potensipenyerapan karbon G. verrucosa dan H. opuntia berturut-turut adalah sebesar 228,73gC/m2/hari dan 1500,57 gC/m2/hari, sedangkan rata-rata potensi penyimpanan karbonG. verrucosa dan H. opuntia berturut-turut adalah sebesar 135,29 gC/m2/hari dan217,01 gC/m2/hari. Kandungan karbon pada G. verrucosa adalah sebesar 4,47 sedangkan H. opuntia sebesar 4,64 . Berdasarkan analisis hasil uji T, potensipenyerapan karbon H. opuntia secara signifikan lebih tinggi dari G. verrucosa danpenyimpanan karbon H. opuntia lebih tinggi dari G. verrucosa namun tidak signifikan.Selain itu, kadar abu pada H. opuntia lebih tinggi daripada G. verrucosa dan kadar airH. opuntia lebih rendah daripada G. verrucosa. Hal tersebut dikarenakan H. opuntialebih banyak menyimpan karbon dalam bentuk zat kapur. Oleh karena itu, usahakonservasi dapat dilakukan pada makroalga yang berpotensi tinggi dalam penyerap danpenyimpan karbon seperti H. opuntia untuk mengurangi emisi karbon dari atmosfer.

Efforts to mitigate climate change by utilizing marine vegetation as a blue carbonabsorber are currently being intensified, one of which is macroalgae vegetation. MuaraBinuangeun, Banten, which is located on the coast of Java, is a potential area as a CO2absorber and is inhabited by various types of macroalgae, including Gracilariaverrucosa which is the macroalgae with the highest attendance frequency and Halimedaopuntia, known as calcareous macroalgae, whose nutrient content have been studied inMuara Binuangeun before. This research was conducted in March May 2018, with theaim to know how much the difference of the carbon absorption and storage potentialbetween Gracilaria verrucosa and Halimeda opuntia in Muara Binuangeun, Banten.The result showed that the average carbon absorption potential of G. verrucosa and H.opuntia was 228.73 gC m2 day and 1500.57 gC m2 day, respectively, while the averagecarbon storage potential of G. verrucosa and H. opuntia were respectively 135.29gC m2 day and 217.01 gC m2 day. The carbon content of G. verrucosa was 4.47 whileH. opuntia was 4.64. Based on the analysis of T test results, the potential of H.opuntia carbon absorption was significantly higher than G. verrucosa and the carbonstorage of H. opuntia was higher than G. verrucosa but not significant. In addition, ashcontent in H. opuntia is higher than G. verrucosa while H. opuntia water content islower than G. verrucosa. It is because H. opuntia stores more carbon in the form ofcalcium carbonate. Therefore, conservation efforts can be done on high potential macroalgaein carbon sinks and storage such as H. opuntia to reduce carbon emissions fromthe atmosphere.

"Sekuestrasi karbon pada makroalga melalui fotosintesis dapat berkontribusi terhadap permasalahan perubahan iklim. Penelitian ini bertujuan untuk menganalisis potensi sekuestrasi karbon pada makroalga Kappaphycus striatum dengan umur pemeliharaan yang berbeda; usia bibit (25 hari) dan usia panen (60 hari). Sampel diambil secara acak pada sistem budidaya lepas dasar, di Desa Alaang, Pulau Alor, Nusa Tenggara Timur. Parameter yang diamati ialah kadar karbon melalui analisis gravimetri. Pengukuran laju pertumbuhan dan eksperimen botol gelap-terang juga dilakukan untuk dianalisis lebih lanjut. Hasil penelitian menunjukkan bahwa potensi sekuestrasi karbon pada lahan budidaya rumput laut seluas 1,552 m2 ialah sebesar 13.28 ton C/siklus tanam untuk makroalga usia bibit dan 26.23 ton C/siklus tanam untuk makroalga usia panen. Nilai ini secara berturut-turut setara dengan 66.07 ton C/ha/siklus tanam dan 125.51 ton C/ha/siklus tanam. Berdasarkan hal ini, potensi sekuestrasi karbon pada makrolaga usia panen 32.78 % lebih besar daripada makroalga usia bibit. Hasil juga menunjukkan bahwa potensi sekuestrasi karbon dapat dipengaruhi oleh laju pertumbuhan dan produktivitas primer. Selanjutnya, manajemen kawasan budidaya rumput laut dengan mengintegrasikan nilai ekologi dan nilai ekonomi, dapat berpotensi untuk menyediakan berbagai manfaat baik bagi masyarakat maupun lingkungan.

Carbon sequestration on macroalgae through photosynthesis can contribute to the mitigation of climate change problem. This research aimed to analyse carbon sequestration potential on macroalgae Kappaphycus striatum with different harvested ages; i.e. young (25 days) and adult (60 days). Samples were collected randomly from off-bottom seaweed aquaculture system, at Alaang Village, Alor Island, East Nusa Tenggara. The parameter observed was carbon content determined by using gravimetric analysis. Growth rate measurement and light-dark bottle experiment were also conducted to be further analysed. Results showed that total area of seaweed aquaculture in Alaang Village was 1,552 m2. According to our analysis, it was estimated that the carbon sequestration potential of macroalgae Kappaphycus striatum was 13.28 tonnes C/cycle for young and 26.63 tonnes C/cycle for adult. These results were equal to 66.07 tonnes C/ha/cycle and 125.51 tonnes C/ha/cycle, respectively. Therefore, the carbon sequestration potential of adult was higher about 32.78% than that of young. It can be concluded that the carbon sequestration potential was influenced by growth rate and primary productivity. Further study on sustainable management of seaweed aquaculture sites, by considering ecological and economic values, could potentially provide multiple
functions both for human and ecosystem.
