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 kaya senyawa bioaktif yang bermanfaat bagi manusia dan organisme lainnya. Tujuan penelitian ini adalah untuk menentukan aktivitas inhibisi tirosinase pada ekstrak etanol rumput laut U. lactuca secara in vitro. Penelitian ini dilakukan secara bertahap, yaitu proses maserasi U. lactuca dengan pelarut etanol. Ekstrak difraksinasi cair-cair dengan pelarut n-heksana, kloroform, dan air. Ekstrak etanol dan fraksi diuji total fenol, total flavonoid, dan aktivitas inhibisi tirosinase. Nilai total fenol dan flavonoid tertinggi didapatkan dari fraksi n-heksana dengan nilai 9,43±0,27 mgGAE/g dan 9,20±0,49 mgQE/g. Aktivitas inhibisi tirosinase tertinggi diperoleh dari fraksi n-heksan dengan nilai IC50 127,74±6,47 µg/mL. Senyawa aktif yang berperan penting dalam aktivitas inhibisi tirosinase pada ekstrak etanol dan fraksi n-heksana meliputi kalkon, asam ferulat, asam 4-nitrocinamat, asam 4-aminobenzoat, derivat 2TMS, asam 4-hidroksibenzoat, 4-tert-butylfenol, 1-tetradekanol, ester metil asam n-heksadekanoat, asam palmitat, 2-(2-Aminofenil)-1H-benzimidazol, dan asam 5-metilsalisilat. Fraksi n-heksana U. lactuca dapat digunakan sebagai inhibitor tirosinase alami.

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.

Abstract

In Indonesia, plastic waste is the main source of the build up of garbage in landfill sites. It is also kinds of garbage that pollutes the environment because it is difficult to decompose in natural process. The problems occur in the society now is that they are unable to manage their waste effectively. If the problem is not managed properly, it will bring negative effects for the environment. This community services activity was held in Cot Seumeureng Village, West Aceh. The aim of this community service activity is to increase the society awareness on the importance of protecting and taking care of the environment in order to be clean and healthy and free of plastic waste. The methods used in this activity are the ecobrick management training and recycle it to be household appliances. The result of this activity is the increasing awareness of the society in managing the waste and recycle it using ecobrick and also to support the economy of the society in the area. Therefore, it can be concluded that plastic waste can help the community’s income by the use of plastic waste to be ecobricks and protect the environment from plastic waste.
