RINGKASAN
VISTER EFRAIM AMONIO GULO.Karakterisasi Asam Amino dan Asam lemak Rumput Laut Padina sp. Di Malang Rapat, Kabupaten Bintan. Dibimbing oleh JUMSURIZAL dan AIDIL FADLI ILHAMDY.
Rumput laut merupakan salah satu komoditas unggulan yang kaya nutrisi dan senyawa bioaktif potensial untuk kesehatan manusia (Brown et al., 2014).
Rumput laut Padina sp. Masuk dalam kelas Phaeophyceae ( rumput laut coklat).
Habitat rumput laut padina biasanya hidup pada karang mati, ataupun merambat di bagian-bagian karang. Rumput laut dan tumbuhan pada umumnya menyimpan cadangan makanannya dalam bentuk karbohidrat terutama polisakarida, serta mengandung sedikit lemak (Handayani et al., 2004).
Rumput laut Padina sp. hanya dimanfaatkan dalam bentuk kering dan di jual dalam bentuk kering. Masih belum ada produk turunannya yang diolah oleh industri-industri pengolahan rumput laut yang ada di Indonesia. Tujuan peneliti melakukan uji asam amino dan asam lemak pada rumput laut Padina sp. untuk mengetahui nilai nutrisi yang terkandung di dalam rumput laut padina sp.
sehingga mempermudah masyarakat, pelajar, para peneliti, dan pemerintah dalam memperoleh informasi tentang nutrisi yang terkandung di dalam rumput laut Padina sp. sehingga dapat memaksimalkan pemanfaatan rumput laut Padina sp yang ada di Malang Rapat Kabupaten Bintan.
Penelitian ini dilaksanakan pada bulan desember 2021. Sampel rumput laut Padina sp. Diperoleh dari perairan laut Malang Rapat Kabupaten Bintan. Uji asam amino, asam lemak, dan proksimat dilaksanakan di SIG Kantor Pusat &
Laboratorium, PT. Saraswanti Indo Genetech, Bogor. Alat dan bahan yang digunakan pada pengujian ialah High Performance Liquid Chromatography (HPLC), spatula, pisau, saringan, kertas bebas nitrogen, cawan porselen, elenmeyer, alat destruksi kjeldahl, peralatan destilator uap, timbangan analitik, pemanas listrik, penyangga, kondensor, ekstraktor soxhlet.
Hasil pengujian asam amino pada penelitian ini ada 18jenis asam amino.
Analisis asam lemak pada penelitian ini meliputi 51 jenis asam lemak. Hasil analisis proksimat rumput laut coklat Padina sp. berdasarkan pengujian yang sudah dilakukan dapat dilihat bahwa kadar abu yang terdapat dalam rumput laut coklat Padina sp. adalah sebanyak 39,41%. Kadar lemaknya 2,67%. Untuk kadar airnya sebanyak 13,87%. Kadar karbohidratnya sebanyak 38,12% serta kadar proteinnya sebanyak 5,94%.

SUMMARY
VISTER EFRAIM AMONIO GULO. Characterization of Amino Acids and Fatty Acids of Padina sp. Seaweed. In Malang Rapat, Bintan Regency. Supervised by JUMSURIZAL and AIDIL FADLI ILHAMDY.
Seaweed is one of the leading commodities rich in nutrients and potential bioactive compounds for human health (Brown et al., 2014). Padina sp. seaweed.
Enter the class Phaeophyceae (brown seaweed). Padina seaweed habitat usually lives on dead coral or propagates in parts of the coral. Seaweed and plants generally store their food reserves in the form of carbohydrates, especially polysaccharides, and contain little fat (Handayani et al., 2004).
Padina sp. seaweed. is only used in dry form and sold in dry form. There are still no derivative products processed by seaweed processing industries in Indonesia. The researchers aimed to test amino acids and fatty acids in Padina sp.
seaweed. to determine the nutritional value contained in Padina sp. making it easier for the public, students, researchers, and the government to obtain information about the nutrition contained in Padina sp. seaweed. to maximize the utilization of Padina sp seaweed in Malang Rapat, Bintan Regency.
This research was conducted in December 2021. Samples of Padina sp.
Obtained from the sea waters of Malang Rapat, Bintan Regency. Amino acid, fatty acid, and proximate tests were carried out at the Central Office &
Laboratory, PT. SIG Saraswanti Indo Genetech, Bogor. The tools and materials used in the test were High Performance Liquid Chromatography (HPLC), spatulas, knives, filters, nitrogen-free paper, porcelain cups, elenmeyer, kjeldahl destruction tools, steam distillation equipment, analytical scales, electric heaters, buffers, condensers, extractors soxhlet.
The results of testing the amino acids in this study were 18 types of amino acids. The analysis of fatty acids in this study included 51 types of fatty acids.
Proximate analysis results of brown seaweed Padina sp. based on the tests that have been carried out, it can be seen that the ash content contained in the brown seaweed Padina sp. is as much as 39.41%. The fat content is 2.67%. For water content as much as 13.87%. The carbohydrate content is 38.12% and the protein content is 5.94%.
