Abstract

The use of synthetic dyes as color enhancers or generators has caused various environmental and health problems. Plant tannin biomordants offer an alternative solution to address these issues. The sample used in this study were Cengkodok (M. malabathricum) plants that grow wild in places that get enough sunlight such as shrubs. Phytochemical screening on various parts of the cengkodok plant revealed that the highest tannin content is found in the leaf. However, until now there has been no scientific evidence that presents differences in tannin levels in cengkodok leaf with various types of solvents. This study aims to determine the yield and total tannin content of cengkodok leaf extract obtained through maceration process using methanol, ethanol, and ethyl acetate solvents. The extract yield was determined by comparing the weight of the dry extract with the powdered cengkodok leaf material. The total tannin content was analyzed using UV-Vis spectroscopy at a wavelength of 755.8 nm with Folin-Ciocalteu reagent and sodium carbonate. Tannic acid was used as a reference. The research results showed that the yield values for Cengkodok leaf extracted with methanol, ethanol, and ethyl acetate were 5.05%, 4.72%, and 1.59%, respectively. The total tannin content of cengkodok leaf extracts with methanol, ethanol, and ethyl acetate solvents was 0.47%±0.04, 0.37%±0.01, and 0.19%±0.04, respectively. Based on this research, it can be concluded that methanol is the most effective solvent in extraction and determination of total tannin content of Cengkodok leaf extracts.

Abstract

The use of metal mordants in fabric dyeing can harm the environment and health, so it is necessary to look for natural mordants that are more environmentally friendly. The utilization of Simpur Air leaves (Dillenia suffruticosa) as a biomordant is one of the efforts to produce a more environmentally friendly tannin mordant. D. suffruticosa has been reported to contain tannin compounds in all parts of the plant. However, scientific evidence of differences in the total tannin content of methanol extracts of D. suffruticosa leaves with various extraction methods have not been found so far. This study aims to determine the effect of different extraction methods on the yield value and total tannin content of methanol extracts of D.suffruticosa leaves using UV-Vis spectrophotometric method at a wavelength of 755.8 nm with Folin Ciocalteau reagent. D. suffruticosa leaves are extracted by using three methods, namely maceration, soxhletation and reflux. Tannic acid is used as a comparator. The results show that the yield value of D. suffruticosa leaves extracted by maceration, soxhletation and reflux methods were 8.35%; 12.26%; and 25.24%, respectively. The total tannin content of methanol extract of D. suffruticosa leaves with maceration method is 0.15% ± 0.007; soxhletation is 0.18% ± 0.007 and reflux is 0.21% ± 0.016.  Based on the results of the data analysis, the significance value <0.05 was obtained. It can be concluded that the extraction method affects the yield value and total tannin content of methanol extract of D. suffruticosa leaves.

Abstract

AbstractThe use of heavy-metal mordants in fabric dyeing is prohibited due to the resulting impacts such as environmental damage and public health, therefore environmentally friendly and non-toxic mordants such as tannin mordants (biomordants) are needed. Based on phytochemical screening on fern species (Pteridophyta), it is known that they contain tannins. However, scientific evidence of determining the total tannin content of various species of ferns has so far not been found. This study aims to determine the yield and total tannin content of methanol extracts of five fern species, namely paku kawat (Lycopodium cernuum), paku resam (Gleichenia linearis), paku dayak (Blechnum orientale), paku uban (Nephrolepis biserrata), paku miding (Stenochlaena palustris). Sample extraction was carried out by maceration method using methanol solvent. Extract yield was determined by weighing method. Analysis of total tannin content was carried out by UV-Vis spectrophotometric method at a wavelength of 755.8 nm using Folin-Ciocalteu reagent and sodium carbonate. The results of the research obtained the yield of methanol extracts on paku kawat, paku resam, paku dayak, paku uban, and paku miding are 11.271%; 8.389%; 4.810%; 3.615%; and 0.854%, respectively. Total tannin levels in methanol extracts of paku kawat, paku resam, paku dayak, paku uban, and paku miding were 0.024% ± 0.002; 0.256% ± 0.029; 0.272% ± 0.037; 0.143% ± 0.019; and 0.022% ± 0.012, respectively. Based on these data, it can be concluded that the methanol extract of paku kawat produces the highest yield while paku dayak produce the highest total tannin content. The results indicate that differences in fern species cause differences in tannin levels.

Abstract

Kegiatan pelatihan pembuatan tas goodie bags pada Kelompok Sadar Wisata (POKDARWIS) di Desa Teluk Makjantu bertujuan untuk memberikan pemahaman kepada POKDARWIS untuk menjaga lingkungan dengan melakukan pengelolaan sampah 3R. Sampah pelastik dipilih karena pemakaian kantong pelastik yang sudah menjadi barang yang tidak terpisahkan dari kehidupan manusia serta memiliki sifat yang sulit terdegradasi (nonbiodegradable) di lingkungan. Goodie bags berbahan dasar limbah pelastik diharapkan dapat menjadi wadah penyimpanan souvenir bagi POKDARWIS Desa Makjantu dalam melayani wisatawan. Pelatihan ini dilakukan dengan menyajikan teori dan praktek pembuatan goodie bags secara langsung, diharapkan masyarakat POKDARWIS dapat melakukan pengelolaan sampah dengan konsep 3R dan dapat membuat goodie bags dari limbah pelastik sebagai upaya pelestarian dan pengelolaan lingkungan. Pelatihan ini juga memberikan dampak terhadap keterampilan peserta dalam mengelola limbah pelastik menjadi barang yang dapat dimanfaatkan. Dengan demikian, program mengelolaan sampah dengan metode 3R dapat diterapkan. Melihat kondisi dan antusias peserta dapat dikatakan bahwa kegiatan ini sangat memberikan dampak positif bagi masyarakat Desa Teluk Majantu untuk  mendukung kegiatan pariwisata dalam hal pengelolaan sampah pelastik dengan tingkat kebermanfaatan dan keberlangsungannya sebesar 90%

Abstract

Spons laut merupakan salah satu sumber bioaktif laut yang kaya akan metabolit sekunder. Metabolit ini meliputi alkaloid, terpenoid, steroid, dan lakton, yang berpotensi sebagai senyawa antimikroba, antiinflamasi, dan antikanker. Penelitian ini bertujuan untuk mengkarakterisasi senyawa metabolit sekunder dari fraksi diklorometana spons laut yang berasal dari famili Thorectidae. Tahapan penelitian meliputi uji fitokimia, isolasi dan pemisahan serta identifikasi senyawa. Hasil uji fitokimia terhadap fraksi diklorometana spons famili thorectidae menunjukkan adanya metabolit sekunder dari golongan alkaloid, steroid dan fenolik. Karakterisasi isolat L5.T2.I2 dengan serium sulfat menunjukkan adanya golongan steroid karena terdapat pembentukan warna coklat kehitaman dan diperkuat dengan spektroskopi FTIR yang menunjukkan adanya beberapa gugus fungsi berupa OH, gugus -CH alifatik C=O karbonil, C=C aromatik, C-H alkena dan OH fenol, yang mengindikasikan kemungkinan adanya senyawa steroid.

Abstract

Erythro-carolignan E (1) has been obtained from the ethanol extract of the wood bark of Durio affinis Becc. This research was conducted in order to prove that conformational preferences of compound 1 were solvent dependent. On the basis of 1H-NMR data, the relative configuration of compound 1 was characterized by a coupling constant (3JHH) value of 3.3 Hz at H-7' in CDCl3. The coupling constant (3JHH) values of H-7' in compound 1 has changed to 4.1 Hz and 5.3 Hz in pyridine-d5 and acetonitrile-d3 respectively. As a result, the conformation of compound 1 at C7'-C8' has changed in different NMR solvents.  In conclusion, structure oferythro-carolignan E that contains a dihydroxy group at C7'-C8' is able to change in different NMR solvent.
