Abstract

This study aims to determine the effect of NaOH concentration and the ratio of monocloro acetic acid with chitosan used in the synthesis process to the degree of substitution and solubility in water. Preparation of carboxymethyl chitosan (CMCts) was carried out by various concentration of NaOH and ratio of monochloro acetic acid with chitosan. The concentration of NaOH used in the alkalination process were 10, 20, 30, 40, and 50% (w/v). The ratio of chitosan: monochloro acetic acid used for etherification were 1:0,5; 1:1; 1:1,5; and 1:2 (w/w). Etherification was carried out at a temperature of 60°C for 2 hours. The results showed that the NaOH concentration of 10-30% (w/v) increased the substitution degree and solubility of produced CMCts. But at concentrations above 30% (w/v) the substitution degree and solubility were decreased. The ratio of chitosan : monochloro acetic acid also affect to substitution degree and the solubility of synthesized CMCts. The higher amount of monochloro acetic acid added to chitosan, the higher is substitution degree and the solubility of carboxymethyl chitosan synthesized in water. The best result was obtained when the ratio of chitosan : monochloro acetic acid were 1:2 (w/w). Within this ratio a 92.05% of yield was resulted with a solubility of 28.05 g/L and a substitution degree of 0.72.

Abstract

In recent years, the search for new anticancer drugs from local plants in Indonesia has become an interesting topic for research. One of the typical Indonesian local plants that have been used by the community as an anticancer traditional medicine (jamu) is Spatholobus littoralis Hassk (SLH) or better known as Bajakah. The native Dayak people of Kalimantan have used it for years for the treatment of breast cancer. In this study, the separation of single compounds from the ethyl acetate fraction of SLH stems was carried out, their molecular structure was analyzed, and anticancer bioactivity was tested. The isolation used the preparative HPLC method. The elucidation of the isolates from the ethyl acetat fraction used LCMS-MS, FTIR, and NMR. Anticancer bioactivity was determined using the MTT bioassay. The result is the acquisition of two isolates; it has been predicted that both are pseudobaptinin. The anticancer IC50 of the pseudobaptinin was 62.85 ppm, and Pseudobaptinin with impurities was 145.60 ppm.

Abstract

Uncaria gambir Roxb (URG) is one of the plants from West Kalimantan predicted to contain antioxidant and anti-breast cancer. This study aims to test the antioxidant and anti-breast cancer potential. UGR leaves were extracted by infusion method using water for 15 minutes with 4 repetitions at a temperature 70oC. A thick extract of 96.2351 grams (29.979%) was obtained from a sample weight of 321 grams of dried UGR leaves. In vitro antioxidant assay of the extract was investigated using 2,2-diphenylpicrylhydrazyl (DPPH) with positive control using quercetin and ascorbic acid, and the Ferric Reducing Antioxidant Power (FRAP) method. In silico screening showed that the biological agents in UGR had the potential as TP53 expression enhancer, antioxidant, anticarcinogenic, chemopreventive, and free radical scavenger. The antioxidant bioassay results showed IC50 values of 81.21 μg/mL, 73.39 μg/mL, and 9.17 μg/mL in DPPH for extract samples with positive control quercetin, sample extracts with positive control Vitamin C and Vitamin C with positive control quercetin, respectively. Meanwhile, the antioxidant activity of extract samples with the FRAP method showed value of 66,05 μg/mL. Anticancer bioassay result showed that UGR leaves extract with water solvent had the stron potentgial to inhibit 4T1 cells with IC50  87.72 μg/mL.

Abstract

Ganoderma sp. is a pathogenic fungus that causes basal stem rot in oil palms, leading to significant yield losses. This study explores the antifungal potential of Uncaria gambir Roxb. extract against Ganoderma sp. using in silico and in vitro methods. In silico analysis from the KNApSAcK and PASS Online databases identified 18 secondary metabolites with probability activity (Pa) values ranging from 0.5 to 0.7, indicating high potential. Cinchonain Ia, an alkaloid with the highest Pa value of 0.638, has poor solubility. In vitro tests on U. gambir extract at various concentrations (0%, 1.5%, 2%, 2.5%, and 3%) showed that the extract was ineffective in inhibiting the growth of Ganoderma sp. Further research with variations in solvents, extraction methods, and formulations is needed to optimize the antifungal activity of this extract.

Abstract

Dewasa ini dunia perfilman bukan hanya persoalan bagaimana menghibur penonton melainkan penyampaian pesan-pesan moral yang terdapat dalam kandungan film. Tidak hanya film-film yang dijumpai di bioskop dan televisi saja, kini film juga berkembang jenisnya seperti film pendek. Dari sekian banyaknya film-film yang bermunculan, film pendek “jendela” karya Randi Pratama merupakan salah satu film yang penuh akan muatan moral. Sang sutradara menggarap film Jendela berdasarkan pengalaman hidupnya, tentang bagaimana hubungan anak laki-laki dan seorang ayah yang mempunyai rasa canggung dalam berinteraksi satu sama lain. Penelitian ini menggunakan metode ilmu Semiotika versi Rolland Barthes yang mencari tanda, makna serta dialog yang mempunyai catatan moral yang kemudian ditafsirkan dengan makna denotasi dan konotasi. Metodologi yang digunakan dalam penelitian ini adalah library research. Upaya analisis pesan moral film “Jendela” menemukan sedikitnya empat pesan moral  yang terungkap dalam film berdurasi 30 menit yang ditampilkan melalui makna denotasi dan konotasi yaitu, pertama menghargai makanan selaku wujud rasa syukur atas rezeki yang diberikan oleh sang pencipta Allah S.W.T. Pesan moral kedua adalah bersabar ketika menghadapi ujian dan masalah. Ketiga. Pengorbanan besar sosok ayah dalam menuju jalan kesuksesan dan kebahagian anak. Dan yang keempat, adalah anak yang berbakti kepada orang tua. Konklusi dari penelitian ini bahwa film Jendela memberikan pesan moral yang disampaikan melalui adegan dan narasi yang tercipta. Peneliti menyadari bahwa dalam penelitian yang diteliti pasti terdapat kekurangan dan banyaknya kelemahan seperti masih banyaknya pesan-pesan moral yang belum terungkap dalam analisa film ini dan teori yang belum sempurna. Maka peneliti memberikan saran selanjutnya kepada peneliti kedepannya untuk terus menambah literasi demi mempertajam analisa pada objek yang diteliiti.
