Abstract

Rambutan hitam atau maritam (Nephelium ramboutan-ake) merupakan tumbuhan tropis khas Kalimantan Timur. Tumbuhan ini tumbuh liar dihutan-hutan Kalimantan. Secara empiris, masyarakat setempat menggunakan buah rambutan hitam untuk pengobatan kanker. Namun demikian, penelitian ilmiah mengenai rambutan hitam masih sangat terbatas. Oleh karenanya, penelitian ini bertujuan untuk menganalisis aktivitas antioksidan dari buah rambutan hitam dengan menggunakan metode DPPH, ABTS, dan FRAP. Analisis aktivitas antioksidan dilakukan secara kolorimetri menggunakan spektrofotometer UV-Vis pada panjang gelombang tertentu. Hasil penelitian ini mengungkapkan bahwa ekstrak etanol daging buah rambutan hitam memiliki aktivitas antioksidan dengan kategori kuat baik dianalisis menggunakan metode DPPH (IC50 = 32,51 ± 0,21 mg/L), ABTS (IC50 = 30,04 ± 0,31 mg/L), dan FRAP (EC50 = 34,22 ± 0,17 mg/L). Aktivitas antioksidan yang kuat dari rambutan hitam menggambarkan potensi yang besar dari rambutan hitam dalam mengurangi dampak negatif radikal bebas. Adapun aktivitas antioksidan buah rambutan hitam dilaporkan pertama kali pada tulisan ini.

Abstract

A workshop on making gummy candy based on stingless bee honey was held in Bangun Rejo Village, Kutai Kartanegara Regency, as an effort to empower the community through innovation in locally processed food products. The aim of this activity was to improve the skills of MSME actors and village residents in producing stingless honey gummy candy, and to elevate the added value of local honey. The methods used included a short theoretical session about the composition of stingless bee honey and the technical process of gummy candy production, a live demonstration, group practice among participants, as well as evaluation via pre-test and post-test on understanding and skills. The workshop was attended by 50 participants from various MSMEs and community groups. Results showed that after training there was an increase in participant understanding by approximately 75% compared to before the training. Furthermore, participants succeeded in making gummy candy with a chewy texture, the natural sweetness of stingless bee honey, and a distinctive aroma that was well accepted in organoleptic tests. This workshop made a tangible contribution to local product diversification, increasing production capacity, and the potential enhancement of village income through signature products based on stingless bee.

Abstract

Exploration the antibacterial activity of S.trifasciata Prain. is still limited, therefore this study aims to assess the antibacterial activity of extracts and ethyl acetate fractions of Sansevieria trifasciata Prain. The S.trifasciata leaves was macerated with ethanol 96%, then fractionated using the trituration method with ethyl acetate. The treatment group was divided into positive control group (PC) using ciprofloxacin, negative control (NC) using DMSO, extract, ethyl acetate fraction 5% (ET5%), 10% (ET10%), 20% (ET20%), 40% (ET40 %). Data were analyzed statistically by ANOVA and chemometrically with PCA. The inhibition zone for S.aureus bacteria in each sample is 26.69; 1.40; 23.32;2.82; 6.23; 11.11; 20.15 mm, respectively, E.coli is 26.65;0.63;22.65;3.61;7.11;11.44;21.15 mm respectively, P. aeruginosa is 27.40; 0.00; 23.23; 2.74;7.03;11.69;21.36 mm respectively. Percent inhibition of extract, ET5%, ET10%, ET20%, ET40% on S. aureus bacteria is 82.16; 5.31; 18.12; 36.39; 70.38% respectively, E.coli is 82.67; 11.13; 24.31; 40.56; 76.99% respectively, P. aeruginosa 84.85; 10.01; 25.65; 42.68; 77.98% respectively. Extract and ethyl acetate fraction have significant potential as antibacterial (p<0.05). The results of PCA chemometric analysis showed that the extract and ET40% had similar inhibition zone area to the positive control ciprofloxacin. The extract and the ethyl acetate fraction 40% are promising for development as antibacterials. Keywords:          Sansevieria trifasciata Prain., chemometric, bacterial

Abstract

Air freshener gel is a semi-solid fragrance product that uses carrageenan and pectin as gel-forming components to overcome unpleasant odors when in a room with high temperatures. The purpose of this study was to determine the composition of carrageenan and pectin as gel-forming materials for air fresheners and the composition of the aroma comparison of mint oil (Mentha piperita L.) and lemon (Citrus limon (L) Burm F). The gel base was made with a ratio of carrageenan: pectin concentration of 1: 2; 1.8: 1.2; 2.5: 0.5 then the base was evaluated including organoleptic examination, stability test and gel hardness. The best base was then added with mint oil and lemon with a ratio of 1: 1.5; 1.25: 1.25; 1.5: 1 and the gel preparation was evaluated with organoleptic parameters, gel stability, gel hardness, liquid evaporation, fragrance resistance and hedonic test. The results of the study showed that the best base preparation after the evaluation of the base was a ratio of carrageenan: pectin concentration of 25: 0.5. Evaluation of the preparation with the addition of mint leaf oil (Mentha piperita L.) and lemon (Citrus limon (L) Burm F) to the base showed a value that was not too significant in the evaluation results. In the hedonic test, the formula with the addition of 2.5%: 2.5% mint leaf oil (Mentha piperita L.) and lemon (Citrus limon (L) Burm F) was the formula preferred by the panelists. So it can be concluded that the carrageenan and pectin combination room freshener gel with a concentration ratio of 2.5: 0.5% can be formulated as a base for room freshener gel preparations, namely producing a chewy and elastic gel base. The formulation of the most preferred combination of mint leaf essential oil and lemon oil as a gel fragrance is with a concentration of 2.5: 2.5%, because it produces a refreshing aroma
