Abstract

The Bima Brebes, variety of shallots, was in high demand, which led to mixing with other varieties. Derivative spectrophotometric fingerprinting combined with chemometrics was used to distinguish between authentic and adulterated shallot varieties. The objective of this study was to identify the original spectra and their derivative spectrophotometric fingerprinting, as well as classify and differentiate between shallot varieties using chemometrics. UV-Visible (UV-Vis) spectrophotometry was used to test essential oil samples from three shallot varieties and their mixtures, followed by spectral derivatization. The spectral data revealed distinct patterns for each sample, including individual varieties and mixtures, and was then analyzed using Principal Component Analysis (PCA) and Partial Least Square-Discriminant Analysis (PLS-DA). The original spectra and their derivatives showed similarities across the samples. PCA and PLS-DA results indicated that the second-order derivative data provided the greatest separation, with a total Principal Component 1 (PC1) and Principal Component 2 (PC2) value of 62.2%, a total component 1 and 2 value of 60.1%, and the highest Variable Importance in the Projection (VIP) score wavelength of 225 nm. The PLS-DA results were validated to ensure that the model was not overfit, as evidenced by a satisfactory cross-validation quality (Q2/R2) value of 0.693 and a significant permutation test. The combination of derivative spectrophotometry fingerprinting and a chemometric approach effectively classified different samples, allowing for the determination of the authenticity of a specific shallot variety.

Abstract

Stabilitas oksidatif digunakan untuk mengukur perubahan kualitas minyak seiring dengan cara, suhu dan lama waktu simpan. Stabilitas oksidatif dapat diukur menggunakan bilangan peroksida. Dalam penelitian ini telah diteliti mengenai pengaruh cara, suhu, lama waktu penyimpanan terhadap stabilitas oksidatif minyak hati ikan cucut botol. Bilangan peroksida diukur menggunakan titrasi iodimetri. Data dianalisis menggunakan statistik deskriptif dan Anova yang diikuti dengan uji Tukey untuk mengetahui perbedaan antar kelompok perlakuan. Kelompok dengan suhu 25 0C dengan wadah semi transparan dan transparan menunjukkan kenaikan bilangan peroksida yang cukup tajam dibandingkan dengan kelompok dengan wadah gelap dan pada kelompok dengan suhu -28 0C dan 5 0C. Wadah gelap dapat melindungi dari cahaya matahari (sinar uv) sehingga dapat meminimalisir terjadinya oksidasi. Suhu -28 0C dan 50C dapat melindungi minyak hati ikan cucut botol dari oksidasi dan tidak tergantung pada wadah yang digunakan.

Abstract

Chalcones, a class of naturally occurring compounds, exhibit a broad spectrum of biological activities, including anticancer properties. In this study, a series of methoxylated chalcones were synthesized via Claisen-Schmidt condensation and evaluated for cytotoxic activity against breast cancer MCF-7 and prostate cancer DU-145 cell lines. The synthetic route involved Claisen-Schmidt condensation, leading to various methoxy-substituted chalcone derivatives. The structures of the synthesized chalcones were confirmed through NMR and mass spectrometry. Cytotoxicity was assessed using the PrestoBlue assay, with 4-bromochalcone (compound 2) displaying the highest cytotoxic activity against MCF-7 cancer cell lines (IC50 = 26.99 µM). These results indicate that methoxylated chalcones hold promise as potential lead compounds for the development of new anticancer agents targeting breast and prostate cancer.

Abstract

Pemberdayaan kelompok PKK Desa Welahan Wetan merupakan upaya strategis dalam meningkatkan kesejahteraan masyarakat melalui penguatan ekonomi lokal berbasis potensi alam. Sebelum program dilaksanakan, komunitas sasaran menghadapi sejumlah tantangan, antara lain keterbatasan ekonomi rumah tangga, rendahnya keterampilan teknis dalam budidaya tanaman obat, serta belum optimalnya pemanfaatan lahan pekarangan yang relatif sempit. Hasil identifikasi awal menunjukkan bahwa lebih dari 60 persen anggota PKK belum memiliki pengetahuan standar mengenai budidaya Tanaman Obat Keluarga (TOGA), dan sekitar 70 persen pekarangan rumah belum dimanfaatkan secara produktif. Program ini berfokus pada pemanfaatan TOGA dan lahan pekarangan produktif dalam pot (TOGA-LAMPOT) sebagai basis pengembangan produk unggulan berbasis ekonomi lokal. Metode pelaksanaan menggunakan pendekatan partisipatif yang melibatkan anggota PKK secara aktif melalui pemetaan kebutuhan mitra, penyuluhan potensi ekonomi TOGA-LAMPOT, serta pelatihan budidaya dan pengolahan di pekarangan rumah. Hasil kegiatan menunjukkan peningkatan keterampilan teknis peserta, ditandai dengan keberhasilan sekitar 70% anggota PKK dalam mempertahankan minimal tiga jenis tanaman obat hingga akhir program, serta terbentuknya inisiatif pembentukan Kelompok Usaha Bersama (KUB) TOGA-LAMPOT. Pemberdayaan kelompok PKK melalui integrasi TOGA-LAMPOT dan penguatan ekonomi lokal terbukti efektif dalam mengoptimalkan lahan terbatas menjadi sumber daya produktif, sekaligus melestarikan pengetahuan tradisional tentang tanaman obat. Program ini direkomendasikan sebagai model pemberdayaan ekonomi komunitas berbasis produk alam di wilayah pedesaan dengan keterbatasan lahan dan sumber daya. Empowerment of the PKK Group in Welahan Wetan Village through Strengthening the Local Economy Based on Natural Products: TOGA-LAMPOT Abstraks The empowerment of the PKK women’s group in Welahan Wetan Village represents a strategic effort to improve community welfare through strengthening the local economy based on natural resources. Prior to program implementation, the target community faced several challenges, including limited household economic capacity, low technical skills in medicinal plant cultivation, and suboptimal utilization of relatively small home gardens. The initial needs assessment indicated that more than 60 percent of PKK members lacked standardized knowledge of Family Medicinal Plant (TOGA) cultivation, while approximately 70 percent of household yards had not been used productively. This program focused on utilizing TOGA and productive home-garden cultivation in pots (TOGA-LAMPOT) as a foundation for developing value-added local products. A participatory approach was employed, actively involving PKK members through partner needs mapping, education on the economic potential of TOGA-LAMPOT, and hands-on training in home-garden cultivation and processing. The results demonstrated an improvement in participants’ technical skills, as evidenced by approximately 70 percent of PKK members successfully maintaining at least three types of medicinal plants until the end of the program, as well as the initiation of plans to establish a TOGA-LAMPOT Joint Business Group (Kelompok Usaha Bersama). The empowerment of the PKK group through the integration of TOGA-LAMPOT and local economic strengthening proved effective in optimizing limited land into productive resources while preserving traditional knowledge of medicinal plants. This program is recommended as a replicable model for community-based economic empowerment using natural products in rural areas with limited land and resources.

Abstract

Clove Essential Oil (CEO) has extensive benefits for health, cosmetics, and food. Low extraction yield (<1%) causes relatively high production costs. This becomes an opportunity for deliberate adulteration to gain greater business profits. This study developed a combination of UV-Vis spectrophotometry with chemometrics to separate pure CEO and adulterated CEO. The adulterants used included Corn Oil (CO) and Olive Oil (OO) at several adulteration levels to see their spectrum and absorption profiles using UV-Vis spectrophotometry. The data were analyzed using PCA and HCA chemometric techniques through R Studio 4.3.3 software. The results of UV-Vis spectrophotometry measurements on CEO adulteration showed similarities in the spectrum profiles of pure CEO and adulterated CEO. Data analysis with PCA can separate pure CEO from adultered CEO with a percentage of cumulative variance of the resulting spectrum of 98.2%. The more similar the composition of a particular oil in a sample, the closer the position of the sample to the oil on the score plot of PCA. HCA analysis can cluster pure CEO separately from adultered CEO. Cluster I in the dendogram consists of samples with large CO concentrations, while samples with large CEO and OO concentrations will be included in Cluster II. The combination of UV-Vis spectrophotometry and chemometrics can be used as a method to separate pure CEO from adultered CEO.

Abstract

Skin aging is a complex biological process caused by intrinsic and extrinsic factors. There are various approaches to preventing skin aging, one of which is using herbal nanocosmetics. This narrative review aims to determine the natural ingredients, type of nanoformulations, and its effects of herbal nanocosmetics to prevent skin aging. The method used in this study was searching for articles related to herbal nanocosmetics to avoid aging skin through Google Scholar, PubMed, and Science Direct with the keywords herbal plants, anti-aging, herbal cosmetics, cosmetics, nanocosmetics, nanoformulations, nanoparticles, nanomaterials, and topical delivery. The inclusion criteria were research articles or review articles about herbal plants made into herbal nanocosmetics to prevent skin aging with the topical route of administration published between 2010-2021 in full text. The articles that have been obtained are then selected, reviewed, and analyzed. Herbal plants made into herbal nanocosmetics contain phenolic compounds for nanoformulations used, namely silver nanoparticles, solid lipid nanoparticles (SLN), nanostructured lipid carriers (NLC), nanoemulsions, liposomes, niosomes, ethosomes, and transfersomes. These nanocosmetics herbs affect skin aging, including UV protection, preventing wrinkles and dark spots, moisturizing and brightening the skin. The herbal nanocosmetics prevent the effects of skin aging through some mechanisms such as anti-oxidant, photoprotective agents, modulators of collagen or elastin synthesis, and inhibitors of melanin synthesis.
