Abstract

Metabolomics has emerged as a critical field in understanding biological processes and disease mechanisms, necessitating advancements in analytical techniques to handle complex biological samples. This review explores the global landscape of metabolomics, with a focus on the use of spectroscopy and spectrometry. Techniques such as UV-Vis and Fourier Transform InfraRed (FTIR) spectroscopy offer fast and cost-effective metabolite tracing but are limited by their sensitivity, particularly for low-abundance metabolites. Nuclear Magnetic Resonance (NMR) spectroscopy, despite being less sensitive than mass spectrometry (MS), provides unparalleled structural information, distinguishing metabolites with similar mass-to-charge ratios. NMR's capability to detect metabolites in the 1-10 µM range highlights its effectiveness in metabolomics. This review categorizes advancements in these techniques, starting with global contributions to spectroscopy, followed by detailed discussions on FTIR strategies for metabolite tracing, and concluding with NMR's qualitative and quantitative applications in metabolomics and disease diagnostics. The review underscores the continuous development in sample preparation and data integration, enhancing the accuracy and applicability of these techniques, positioning NMR and FTIR as essential tools in modern metabolomic research.

Abstract

Bajakah plants (Spatholobus suberectus) have been widely used by Dayak tribes in Kalimantan with various properties that are believed and have also been studied for various tests of phytochemical compound content and pharmacological tests. Secondary metabolite compounds from bajakah (Spatholobus suberectus) have potential as psychostimulant compounds. The purpose of this study was to investigate the psychostimulant activity of bajakah plants (Spatholobus suberectus) through analysis of the interaction between bajakah secondary metabolite compounds and the 4M48-Dopamine Transporter receptor (PDB: 4M48), which is one of the dopamine transporter proteins. Ligand and receptor interactions were analyzed using molecular docking method with Autodock Vina 4 application with nortriptyline compound as native ligand and 15 secondary metabolite compounds for testing. The results of docking analysis showed that the standard ligand nortriptyline compound has an affinity value of -10.2 kcal/mol. There are 3 compounds from bajakah that have affinity values close to the standard compounds plathymenin, butein and eriodictyol with affinity values of -9.7 kcal/mol, -9.4 kcal/mol and -9.2 kcal/mol respectively. Based on the analysis conducted, it can be concluded that bajakah plants (Spatholobus suberectus) have the potential to be developed as psychostimulant therapy.

Abstract

Kurkumin merupakan senyawa aktif yang ditemukan pada kunir, berupa polifenol dengan rumus kimia C21H20O6. Kurkumin memiliki dua bentuk tautomer yaitu keto dan enol. Senyawa-senyawa kurkuminoid terdapat dalam berbagai jenis turunannya. Maka dari itu digunakan sebanyak 25 jenis turunan dari kurkuminoid untuk dilakukan analisa secara komputasi. Analisa ini akan dilakukan dengan menggunakan tiga metode yaitu metode semi empirik AM1, PM3 dan RM1. Hasil yang didapat bentuk keto memiliki energi yang lebih rendah dari pada bentuk enol, hal ini dibuktikan dengan nilai tetapan kesetimbangan yang 21 dari 25 senyawa turunan kurkuminoid memiliki nilai kurang dari satu. Sehingga terlihat bahwa bentuk keto lah yang paling disukai dalam kesetimbangan. Pada saat bentuk keto panjang ikatan rantai karbon memiliki panjang rerata 1.419-1.53435 Å. Sedangkan dalam bentuk enol panjang ikatan karbonnya berkurang dengan rerata 1.3814-1.50251 Å.

Abstract

Tuwung Village, located in the Kahayan Tengah District, Pulang Pisau Regency, Central Kalimantan, has significant potential in managing social forestry land to support food security. The local community, organized in the Social Forestry Business Group (KUPS), has successfully cultivated 120 hives of stingless bees (Trigona sp.), with monthly production capacity of up to 350 mL per hive. Although honey production is abundant, its sales remain very limited due to a marketing strategy that relies solely on word-of-mouth promotion. Therefore, this community service activity was introduced to provide guidance to KUPS Madu Kelulut on branding, product packaging, and digital marketing. With an attractive brand, high-quality packaging, and the right marketing strategy, it is hoped that the stingless bee honey business can become more competitive in a market already saturated with similar products. This community service program involved several stages, including preparation, implementation, and evaluation. The activity was carried out on July 9, 2024, with 40 participants. The evaluation results indicated an 81.25% increase in participants' understanding of branding, product packaging, and digital marketing. Furthermore, the participants successfully created the brand "Madu Kelulut Nyai Hapu," with an appealing packaging design and effective promotional content shared through social media and e-commerce platforms.

Abstract

This study aims to monitor the impact of sulfur dioxide (SO2), a significant contributor to atmospheric corrosion and associated with air pollution, in urban and industrial areas through empirical models of spatial distribution and temporal estimation in Medan. Datasets of Sentinel 5P NRTI are worth using to monitor the formation of sulfate aerosols or SO2 emissions from natural sources and anthropogenic origin in near real-time from 2019 until 2023 on the local scale, Medan. The source dataset covers 1,11 km of spatial image resolution on orbital in daily revisit time with a spectral bound between the ultraviolet and the shortwave infrared. The measurement of atmospheric SO2 concentrations is generated by enumerating the SO2 vertical column density technique at the soil surface with the cloud-based platform The Earth Engine (EE) Code Editor to handle large data sizes and produce interactive mapping. Based on the availability of auxiliary results, the number of spreading SO2 concentrations fell from 0,92 mmol/m2 in 2019 to 0,41 mmol/m2 in 2023, a reduction of 49.98 percent. The average of SO2 concentrations has decreased substantially over the years. Consequently, these pollutants have recorded long-term health and meteorological parameters impact that substances can rise or reduce acid rain.Keywords: Air pollution, Meteorological parameters, Sentinel 5P NRTI, SO2
