Abstract: An isolation and identification of phenolic compounds from Halban Leaves (Vitex pinnata Linn), a traditional medicinal plant in Aceh, has been done. Halban leaves were extracted through methanol maceration followed by isolation. The methanol extract went into n-hexane and ethyl acetate partition consecutively resulting in 3 different fractions of ethyl acetate and n-hexane extract. The ethyl acetate fraction demonstrated the most promising antioxidant and cytotoxic activity. Therefore, purification of ethyl acetate fraction was done by column chromatography [SiO2; (i) n-hexane-ethyl acetate 10:1, 1:1 ; (ii) n-hexane-ethyl acetate = 2 : 1); (iii) n-hexane-acetone = 1:1]. The pure isolate as identified by using UV, IR, NMR, and MS spectra afforded 2 phenolic compounds, namely (1) 4-hydroxymethyl benzoate and (2) p-hydroxymethyl benzoic acid (PHBA). The antioxidant activity of compound 1 and cytotoxicity activity of 2 expressed in IC50 and LD50 was 41.08 ppm and 59.41 ppm, respectively.Abstrak: Isolasi dan identifikasi senyawa fenolik dari Daun Halban (Vite xpinnata Linn) tanaman obat tradisional asal Aceh telah dilakukan. Isolasi ini dilakukan dengan cara mengekstraksi daun halban dengan cara maserasi menggunakan pelarut metanol, Ekstrak metanol kemudian dipartiisi dengan n-heksan dan etilasetat secara berturut-turut sehingga diperoleh tiga ekstrak yaitu ekstrak etil asetat, n-heksan dan air. Ekstrak etil asetat memiliki bioaktivitas sebagai antioksidan dan juga toksisitas. Pemurnian dilanjutkan dengan cara kromatografi kolom [SiO2; (i) n-heksan-etilasetat 10:1, 1:1 ; (ii) n-heksan-etilasetat = 2 : 1); (iii) n-heksan-aseton = 1:1] dan diperoleh isolat murni. Isolat murni tersebut diidentifikasi berdasarkan interpretasi data spektra UV, IR, NMR dan MS. Hasil interpretasi data menunjukkan daun halban (V. pinnata Linn) mengandung dua senyawa fenolik yaitu (1) 4-hidroksi metil benzoat dan (2) asam para hidroksi benzoat (PHBA). Senyawa 1 memiliki aktivitas antioksidan dengan nilai IC50 = 41,08bpj dan senyawa 2 memiliki aktivitas toksisitas dengan nilai LC50 = 59,41.

Abstract: Mercury is a dangerous contaminant for aquatic organisms. Seurukan fish (Osteochilus vittatus) is a type of fish in the Krueng Sabee river that is vulnerable to mercury exposure. The study's purposes were to investigate the effect of mercury on the biometric conditions of Seurukan Fish in the Krueng Sabee River, Aceh Jaya Regency. A total of 90 Seurukan fish consisting of 50 males and 40 females were collected from 3 research stations. The research stations represent the upstream area (Station 1), median river bodies (Station 2), and the downstream area (Station 3). Fish samples were taken from July to August 2019. The main parameters observed included class interval, sex ratio, length-weight relationship, condition factors, mercury concentration in sediment and liver, and hepatosomatic index. The results showed that the mercury content in the sediments of the Krung Sabee River was increased both spatially and temporally. Station 1, located in the upstream area, has the highest mercury content in the sediment was 6.278 ± 0.987 mg/kg. Mercury content in liver of Seurukan Fish ranged from 0.182 ± 0.100 mg/kg to 0.198±0.152 mg/kg. Mercury contamination in the Krueng Sabee river caused a decrease in biometric conditions of Seurukan Fish. Seurukan Fish exposed to mercury tended to have smaller size, an unbalanced sex ratio, low hepatosomatic index value, and negative allometric growth pattern.Abstrak: Merkuri merupakan salah satu jenis kontaminan berbahaya bagi organisme akuatik. Ikan seurukan (Osteochilus vittatus) merupakan salah satu jenis ikan di sungai Krueng Sabee yang rentan terpapar merkuri.

Abstract: Past observations during a disaster identify that when children are separated from parents, they suffer due to the inability to comprehend disaster mitigation concepts. This study proposes a process from the existing framework K-Nearest Neighbor (KNN) and Term Frequency - Inverse Document Frequency (TF-IDF) for extracting a large body of knowledge in the form of documents into simple words. Those simple words can be arranged into contextual lyrics utilizing an Artificial Intelligence lyrics generator and then orchestrated into a song using a music generator. The piece, which is the output of the proposed process, is utilized to transfer the knowledge about earthquake disaster mitigation to children. A quantitative analysis of questionnaires on students aged 9-10 in Banda Aceh shows the song's highly significant effect in transferring the knowledge about earthquake disaster mitigation to children.
