Abstract

Pesisir Aceh Barat memiliki topografi laut yang berhadapan langsung dengan Samudera Hindia dengan beragam biota-biota laut yang tersebar di pesisir dan laut. Salah satu biota laut yang terancam punah adalah penyu laut di alam. Hal ini perlu dilakukan upaya konservasi penyu yang bertujuan mempertahankan populasi hewan tersebut. Oleh karena itu, kami melaksanakan program pengabdian kepada masyarakat dengan melakukan pendampingan menggunakan metode pembelajaran Storytelling kepada siswa/siswi SMAN 1 Samatiga Aceh Barat. Tujuan pelaksanaan pengabdian kepada masyarakat adalah untuk menumbuhkan kesadaran dalam melestarikan penyu laut di pesisir Aceh Barat. Metode pelaksanaan melalui pendekatan individual dan klasikal. Pendekatan klasikal dilakukan pada saat pemberian teori tentang penyu melalui metode bercerita dan pendekatan individual dilakukan pada saat latihan dan pengisian puzzle. Adapun metode yang digunakan adalah metode pembelajaran storytelling. Hasil pelaksanaan pengabdian meliputi penyampaian materi tentang pengenalan hewan penyu dengan metode pembelajaran berbasis retelling story. Berdasarkan hasil kegiatan, dapat diidentifikasi bahwa tingkat pemahaman siswa mengenai penyu melalui metode storytelling adalah sebesar 85%. Hal ini terlihat dari output kegiatan berupa kegiatan retelling story (bercerita kembali) dan penyusunan puzzle. Siswa juga memberi tanggapan positif dan antusias dimana informasi yang disediakan memberikan wawasan mengenai penyu yang ada disekitar mereka. Selain itu, kami melakukan pemutaran video animasi penyu dengan menyajikan konten-konten tentang pola kehidupan penyu di alam dan menyisipkan pesan-pesan moral akan pentingnya melestarikan penyu laut.

Abstract

Pesisir Aceh Barat memiliki potensi sumberdaya kelautan yang tinggi untuk memenuhi kebutuhan hidup manusia. Salah satu potensi sumberdaya kelautan adalah alga laut Sargassum sp. Spesies Sargassum sp merupakan salah satu jenis rumput laut yang memiliki kandungan antioksidan dan antibakteri yang tinggi. Oleh Karena itu, Peneliti melaksanakan kegiatan pengabdian kepada masyarakat meliputi pendampingan mitra PkM dan Sosialisasi pengenalan alga laut Sargassum sp sebagai pengawet alami. Sebagian produsen mie Aceh memproduksi mie Aceh dalam skala besar sehingga mie Aceh tersebut tidak habis terjual. Hal ini menyebabkan produsen mie Aceh kadangkala menggunakan bahan kimia formalin sebagai pengawet mie Aceh. sementara, formalin merupakan bahan kimia yang berbahaya bagi kesehatan apabila dikonsumsi oleh manusia. Tujuan pelaksanaan kegiatan PkM ini adalah untuk memberikan pemahaman kepada mitra dan masyarakat tentang pemanfaatan alga laut Sargassum sp sebagai pengawet alami. Metode pelaksanaan kegiatan PkM meliputi pendampingan mitra PkM dan sosialisasi pengenalan potensi alga laut Sargassum sp sebagai pengawet alami Mie Aceh and knowledge transfer.  Tahapan pelaksanaan kegiatan pengabdian kepada masyarakat meliputi survey ketersediaan bahan baku alga cokelat di perairan Aceh Barat, persiapan alat dan bahan untuk kegiatan sosialisasi kepada masyarakat dan pendampingan mitra PkM sebagai bentuk transfer knowledge. Dalam pelaksanaan kegiatan PkM ini meliputi pendampingan mitra PkM dan sosialisasi kepada masyarakat. Pertama, peneliti melakukan pendampingan mitra dalam pembuatan mie Aceh dengan menambahkan ekstrak alga cokelat Sargassum sp sebagai pengawet alami. Kedua, peneliti melaksanakan sosialisasi potensi alga laut Sargassum sp kepada masyarakat.

Abstract

This study investigated the TOEFL benchmark policy as an exit requirement for Universitas Teuku Umar students. The research method used was survey design hereby the data from the questionnaire and students' TOEFL score were collected. Under the policy, the students have to pass the standard passing score of TOEFL to graduate. 100 non-English major students from Universitas Teuku Umar participated in this study. The results of the study revealed that the participants gave more positive responses than negative ones. The extend of approval for this policy seemed more related to their abilities, awareness of the importance of learning English, and motivation to learn English. The result from TOEFL scores taken from 2018-2019 found that as many as 58% of students failed to obtain minimum criteria (˃ 400) while only 42% of them reached 400 or above. It indicates that Universitas Teuku Umar students are not ready yet to face this policy.  On the other hand, based on the questionnaire result, most students agreed with the implementation of TOEFL as an exit requirement, however, a minimum passing score should be evaluated and a set of students' needs under the policy should be facilitated.

Abstract

Ulva lactuca is rich in bioactive compounds, which are beneficial to humans and other organisms. This study aimed to determine the tyrosinase inhibitory activity of an ethanol extract of U. lactuca seaweed in vitro. This research was carried out in stages, namely, the maceration process of U. lactuca with an ethanol solvent. The extract was liquid-liquid fractionated using n-hexane, chloroform, and water as solvents. The ethanol extracts and fractions were tested for total phenol, total flavonoid, and tyrosinase inhibitory activities. The highest total phenol and flavonoid values ​​were obtained from the n-hexane fraction with values ​​of 9.43±0.27 mgGAE/g and 9.20±0.49 mgQE/g. The highest tyrosinase inhibitory activity was obtained from the n-hexane fraction, with an IC50 value of 127.74±6.47 µg/mL. Active compounds that play an important role in tyrosinase inhibitory activity in the ethanol extract and n-hexane fraction include chalcone, ferulic acid, 4-nitrocinnamic acid, 4-aminobenzoic acid, 2TMS derivatives, 4-hydroxybenzoic acid, 4-tert-butylfenol, 1-tetradecanol, n-hexadecanoic acid methyl ester, palmitic acid, 2-(2-Aminophenyl)-1H-benzimidazole, and 5-methylsalicylic acid. Thus, the n-hexane fraction of U. lactuca could be used as a natural tyrosinase inhibitor.

Abstract

Seaweed contains various bioactive compounds rich in pharmacological potentials, such as antioxidants and anti-arthritic. This study aims to determine the antioxidant and anti-arthritic activities of the methanolic extract of Halimeda tuna. Halimeda tuna samples were extracted using the maceration method and methanol. The methanol extract was tested for antioxidant (2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP)) and anti-arthritic activity using denatured bovine serum albumin (BSA). The methanol extract was also subjected to phytochemical and Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Research results revealed that the extract yield was 0.50 ± 0.06%. Phytochemical analysis showed that H. tuna methanolic extract contained flavonoids, steroids, and alkaloids. GC-MS analysis showed that H. tuna methanolic extract contained steroids, fatty alcohols, and fatty acids. The antioxidant activity tests revealed an IC50 value of 299.98 ± 121.15 ppm and a FRAP value of 200.02 ± 8.50 M/g, categorized as a weak antioxidant. Anti-arthritic activity of H. tuna methanolic extract showed an IC50 value of 877.29 ± 209.84 ppm. The anti-arthritic activity of H. tuna methanolic extract was lower than sodium diclofenac as a standard drug. The extract of H. tuna has antioxidant and anti-arthritic activities; hence, further exploration is needed as an alternative potential in the pharmacological field.

Abstract

Ulva lactuca, a widely available green seaweed, has demonstrated promising bioactivity as a tyrosinase inhibitor. This study aimed to evaluate the tyrosinase inhibitory activity of U. lactuca extracts and identify the active compounds responsible. The seaweed was extracted using methanol via maceration, followed by partitioning with hexane, chloroform, and water. Total phenolic and flavonoid contents were determined using UV-VIS spectrophotometry, and tyrosinase inhibition was assessed in vitro. Among the tested fractions, the hexane fraction exhibited the highest tyrosinase inhibitory activity with an IC50 value of 584.34 ± 35.07 µg/mL, classifying it as an active inhibitor. Although this activity was weaker than kojic acid (IC50 = 11.07 ± 0.86 µg/mL), the hexane fraction showed relatively high phenolic (11.66 ± 0.53 mg GAE/g) and flavonoid (9.75 ± 0.30 mg QE/g) contents. Gas Chromatography-Mass Spectrometry (GC-MS) analysis identified several bioactive compounds, notably 2,4-dimethoxycinnamic acid, chalcone, and derivatives such as 2,6-dihydroxybenzoic acid and phloretin. These findings highlight the potential of U. lactuca, particularly its hexane fraction, as a source of natural tyrosinase inhibitors. This opens avenues for its application in the pharmaceutical and cosmetic industries, especially in formulations targeting hyperpigmentation and skin brightening.
