Abstract

The 2022 Indonesian Ministry of Health's Nutrition Status Survey (SSGI) revealed four prevalent child malnutrition issues in Indonesia: stunting (27.7%), wasting (7.7%), underweight (17.1%), and overweight (3.5%). One source of nutritious food can be obtained from “air serbat,” presenting an entrepreneurial opportunity for students through the Chemistry Education Student Association (HIMDIKIM). This "air serbat" serves as the base ingredient for an ice cream innovation named “Serbato ice cream,” packaged in 50 mL cups. Following entrepreneur recruitment, the community service initiative proceeded with workshops on production and packaging. Test marketing was conducted five times, including one in Sebuyau, Sarawak, Malaysia. Organoleptic test results indicated positive responses towards color, aroma, and sweetness, with the substitution of packaged coconut milk improving smoothness and consistency. Serbato ice cream has obtained HAKI certificate No. EC00202366602, and its sales have generated a profit of 29.6% for HIMDIKIM.

Abstract

This research aims to profile the active antioxidant compounds from leaf extracts of Buas-buas (Premna serratifolia) growing in Pontianak of West Kalimantan (Indonesia) through a metabolomics approach and their activity as anti-COVID-19 candidates by molecular docking. In this study, P. serratifolia leaves were macerated and fractionated using solvents with different polarities. The extracts were then tested for antioxidant activity using the DPPH method, determined the total phenolic content (TPC), flavonoids (TFC), and steroids (TSC), and analyzed antioxidant the functional groups and compounds by Fourier Transform Infrared spectroscopy (FTIR) and Ultra High-Performance Chromatography UHPLC-Q-Orbitrap HRMS. The functional groups on antioxidant activity were determined by Principal Component Analysis (PCA) and Partial Least Square (PLS) regression. Based on a metabolomics approach, the PCA and PLS analysis shows that hydroxyl was the most active antioxidant from P. serratifolia leaves. UHPLC-Q-Orbitrap HRMS analysis showed the presence of scopoletin, esculetin, 7-hydroxycoumarine, matairesinol, hymecromone, and hexylresorcinol in the water fraction of P. serratifolia leaves. Molecular docking with 4YE6, 1OG5, and 3NRZ shows that matairesinol had the most potential as an antioxidant. Mataresinol and hexyresorcinol are phenolic compounds that have great potential as a COVID-19 inhibitor based on molecular docking with 5R81, 7CMD, and 6M2N.

Abstract

The leaves of Buas-buas or Premna serratifolia (P. serratifolia) have been used in Asian countries to treat inflammation, respiratory disorders, and postnatal recovery. Previous studies have demonstrated its anticancer activity against HT-29 and DLD-1 colon cancer cell lines; however, the isolation approach was selective and did not detect the range of active compounds or their functional groups. This study aims to identify functional groups and active compounds using Ultra High Performance Liquid Chromatography–High Resolution Mass Spectrometry (UHPLC-HRMS) and Fourier Transform Infrared Spectroscopy (FTIR) without isolation, and to evaluate cytotoxicity against WiDr cells. The research included ethanol extraction of P. serratifolia leaves, fractionation with n-hexane, ethyl acetate, and water, phytochemical, in vitro cytotoxicity assays, and FTIR and UHPLC-HRMS analyses. Phytochemical screening indicated the presence of flavonoids, tannins, saponins, and steroids. Aside from the ethanol extract, all three fractions showed moderate cytotoxic activity, with the ethyl acetate fraction (IC₅₀ = 49.12 μg/mL) selected for further analysis. FTIR spectra revealed functional groups including –OH, C–H, C=O, C=C, –CH₃, C–O, and =C–H. UHPLC-HRMS identified compounds such as luteolin, quercetin, apigenin, kaempferide, aurantioobtusin, isorhamnetin, scrofulein, and 5,7-dihydroxy-6-methoxy-3-phenyl-4H-chromen-4-one in the ethyl acetate fraction, with mass accuracy ranging from –0.53558 to 3.07641 ppm.

Abstract

The lack of innovation and standardization in Serbato Ice Cream presents a major challenge to product development and market competitiveness. This community engagement program aimed to enhance product value through recipe modification, new variant creation, product standardization, and packaging redesign. The innovation included replacing the red coloring from serbat water with the natural blue pigment of butterfly pea flowers, adjusting the recipe for a smoother texture, and conducting tests on fat, protein, and microbiological content. Repackaging involved adding nutritional information, halal certification, and expiration dates. The results revealed that Bulato Ice Cream contained higher protein (12.45%) than Serbato Ice Cream (2.70%), while Serbato Ice Cream had a higher fat content (2.70%) than Bulato (2.34%). Microbiological analysis confirmed both products were free of bacterial contamination. Sensory tests showed that Bulato Ice Cream was preferred for its color, sweetness, and flavor, while Serbato Ice Cream was favored for its aroma and texture. These innovations not only improved product quality and safety but also contributed economically to HIMDIKIM through the commercialization of attractive, standardized local ice cream products

Abstract

The implementation of the Merdeka Curriculum at the senior high school (SMA) level emphasizes the execution of the Pancasila Student Profile Strengthening Project (P5), which instills character values and local wisdom. However, the learning modules utilized in P5 typically draw inspiration from online sources and frequently neglect to incorporate local potential. On the other hand, the increasing prevalence of diabetes in Indonesia has become an urgent public health issue, while the use of local medicinal plants such as kesum (Polygonum minus) has not been widely integrated into contextual learning in schools. This study aimed to develop a research-based e-module on the medicinal plant Kesum (Polygonum minus) as an antidiabetic, integrated with the Projek Penguatan Profil Pelajar Pancasila (P5). The development followed the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. Data were collected through teacher interviews and validation by nine experts in content, media, and language. Validation results indicated that the e-module was highly valid for use, with an average score of 86.82%. The practicality of the e-module was tested in a small group trial (1students), yielding a score of 80.75% (practical category), and in a large group trial (60 students), resulting in a score of 82.45% (highly practical category). The e-module was designed to support project-based learning by addressing local issues, strengthening students’ scientific literacy, and promoting local wisdom values. Therefore, this e-module is considered suitable as a contextual learning resource for implementing P5 in senior high schools.

Abstract

The secondary metabolites in plants such as Premna serratifolia (P. serratifolia) are influenced by their growing locations, which in turn affects their bioactivity. This study aimed to compare the antioxidant activity and α-glucosidase inhibition of P. serratifolia leaf extracts from the Sintang, Kapuas Hulu, and Sambas districts in West Kalimantan. Antioxidant capacity was evaluated using the DPPH method, while the reduction of α-glucosidase activity was assessed using the PNPG method. Functional groups and active compounds were identified using FTIR and UHPLC-Q-Orbitrap HRMS. The findings indicated that the extract from Kapuas Hulu, obtained through maceration (KHM), exhibited the highest antioxidant activity (IC₅₀ 18.39) and contained the most total phenolic content (TPC). The best α-glucosidase inhibition activity (IC₅₀ 4194.14) was found in the extract from Sambas obtained through Soxhlet extraction (SSI), which had the highest total flavonoid content (TFC). Principal Component Analysis (PCA) revealed that the functional groups and active compounds of P. serratifolia from Kapuas Hulu and Sintang were similar, as both regions are located in eastern West Kalimantan. Additionally, Partial Least Squares (PLS) analysis revealed that the C-H alkane, O-H, and isoferulic acid were the most influential compounds in determining antioxidant activity. At the same time, the C=O group and NP-000308 predominantly influenced α-glucosidase inhibition.
