Abstract

Penderita penyakit kanker payudara diketahui semakin meningkat hampir di setiap negara termasuk juga di Indonesia. Kendatipun bukan merupakan penyakit menular, penanganan kanker payudara perlu mendapatkan perhatian serius karena dapat menyebabkan kematian bagi penderita. Sosialisasi aktif kepada masyarakat mengenai pencegahan dan penanganan penyakit sejak dini merupakan salah satu upaya untuk mengurangi terjadinya kasus ini. Pemahaman mengenai pemanfaatan bahan alam yang berkhasiat dalam terapi kanker payudara juga perlu diketahui oleh masyarakat, untuk memberikan harapan dan mendukung penemuan obat kanker yang berasal dari bahan alam. Penelitian yang dilakukan di desa Ciliang Kecamatan Parigi Kabupaten Pangandaran Provinsi Jawa Barat ini bertujuan untuk mendapatkan informasi tentang pengetahuan masyarakat desa tersebut mengenai penyakit kanker payudara. Metode penelitian dalam pengumpulan data dilakukan dengan kuestioner model tes dikotomi mengenai pengenalan, gejala, faktor penyebab, pemeriksaan payudara sendiri (SADARI), pemanfaatan bahan alam untuk terapi kanker payudara. Pengolahan dan analisis data dilakukan dengan skala likert. Kegiatan penyuluhan dilakukan setelah pengumpulan data untuk memberikan informasi dan penjelasan mengenai kanker payudara dan pemanfaatan bahan alam untuk penyakit tersebut. Hasil penelitian menunjukkan bahwa masyarakat desa Ciliang telah memiliki pengetahuan yang baik mengenai kanker payudara dan pemanfaatan bahan alam untuk penyakit tersebut dengan skor rata-rata responden adalah 17,15 dan rentang nilai 14-21 dari total nilai 25, yang menunjukkan tingkat pengetahuan yang baik hingga sangat baik. Namun, sosialisasi mengenai kanker payudara tetap harus dilakukan berkala terutama mengenai cara deteksi dini melalui teknik SADARI.

Abstract

Sargassum cristaefolium is one of 782 types of seaweed/macroalgae that grows in Indonesia and is known as one of the macroalgae with bioactive compounds having an important role in the development of nutraceuticals for disease prevention and health maintenance. Sargassum cristaefolium extract (SCE) is known for its various beneficial activities such as antimigraine by reducing levels of CGRP and inhibitor of tyrosinase activity in anti-melanogenetics. Nevertheless, due to its hygroscopic viscous extract consistency and fishy odor, a suitable formulation is required to prepare a powder form of SCE and thus could be applied in a suitable dosage form. Our current study aims to develop the extract into suitable powder raw material by applying a solid dispersion technique.  The solid dispersion of SCE was initially prepared by selecting suitable carrier agents such as Aerosil, Microcrystalline cellulose (MCC) PH 101, maltodextrin, and PVP K30 with the extract in a ratio of 1:1, and continued by the combination of the carrier agents. The best powder formula was characterized by its powder characteristic, solubility and powder flow was assessed by its angle of repose, Carr’s index and Hausner ratio.  The experiment results that the optimum formulation for solid dispersion of SCE was obtained by the combination of SCE:PVP: MCC at a ratio of 1:1:3 with a less fishy smell, and excellent powder properties. The composite mixture was estimated due to the formation of hydrogen bonds between the carbonyl group of PVP and the hydroxyl group of SCE’s compound and MCC. In conclusion, solid dispersion of SCE by employing a combination of PVP and MCC can be an alternative to prepared SCE powder with optimum humidity protection and good flowability thus suitable to proceed as solid dosage form.  Keywords: Sargassum cristaefolium, solid dispersion, PVP K30, Microcrystalline                      cellulose PH101

Abstract

Multidrug-resistant (MDR) Klebsiella pneumoniaeis a critical pathogen causing severe human diseases, including pneumonia. Combating the growing threat of MDRK. pneumoniae requires innovative approaches, such as exploring plant-derived antibacterial agents. Rhizophora stylosa Griff., a mangrove species with traditional medicinal uses, is recognized for its bioactive compounds with potential antibacterial properties. However, research on its bioactive constituents remains limited. This study investigated the antibacterial activity of R. stylosa leaf extracts prepared via maceration and liquid-liquid fractionation against K. pneumoniae ATCC 700603. Using agar-well diffusion and cell leakage assays, the water fraction demonstrated moderate inhibition of K. pneumoniae, producing an average inhibition zone of 8.24 mm and a minimum inhibitory concentration (MIC) of 400 mg/ml. UV-Vis spectrophotometry revealed that the water fraction disrupted protein and nucleic acid synthesis, evidenced by leakage of cellular materials at 260 and 280 nm. Additionally, scanning electron microscopy (SEM) images of K. pneumoniae cells treated with the water fraction showed pore formation and structural damage. These results emphasize the antibacterial potential of the water fraction of R. stylosa leaves against MDRK. pneumoniae. Further investigations are necessary to isolate and identify the specific bioactive compounds responsible for these effects. Moreover, comprehensive assessments of activity and toxicity are crucial to advance R. stylosa-based antibacterial agents as promising alternatives for addressing the challenge of MDR bacterial infections.

Abstract

ABSTRACT Natural extracts have potential in the pharmaceutical industry, cosmetics, and clinical applications because they are safe, non-toxic, and have relatively low side effects. Unfavorable taste and odor and stability problems are their disadvantages. The solution to these problems is microencapsulation technology. Microencapsulation is a technology that involves covering or coating a core substance with a polymer wall layer, resulting in micro-sized particles. The benefits of microencapsulation can protect compounds from various environmental factors such as oxidation, degradation, temperature, humidity, and light, thereby extending the shelf life of the product, improving the stability of active ingredients, preventing loss of activity, masking aromatic flavors and odors, improving the stability of volatile compounds and increasing bioavailability. The purpose of this review is to gather information about the application of microencapsulation to natural extracts and what the results of microencapsulation are. The literature review was conducted through Google Scholar and PubMed databases, and the literature selection was done using the PRISMA Flow Chart. This review results in microencapsulation technology for natural extracts made by ionic gelation, spray wet microencapsulation (SWM), solvent evaporation, freeze drying, fluid bed, and spray drying. Each method has a unique way of protecting the core substance with a polymer layer, resulting in useful microcapsules such as to reduce moisture, obtain suitable physicochemical characteristics, good flow rate, retain bioactive compounds, lower hygroscopicity, improve stability, increase shelf life, increase solubility, taste masking, maintain antioxidant content and pharmacological activity of natural ingredient extracts. This means the use of microencapsulation technology promises to improve the utilization of natural extracts in various pharmaceutical industries, cosmetics, and clinical applications. Keywords: Microencapsulation, Natural extracts, Methods, Applications  ABSTRAK Ekstrak bahan alam memiliki potensi dalam industri farmasi, kosmetik dan aplikasi klinis karena aman, tidak beracun dan efek samping relative rendah. tetapi kelemahannya yaitu rasa dan bau yang tidak disukai serta  masalah stabilitas.

Abstract

Facial skin health results from a complex interaction between intrinsic biological processes and extrinsic environmental exposures, extending beyond the effects of topical skincare alone. This narrative review synthesizes evidence from original studies published between 2015 and 2025, retrieved from PubMed and Google Scholar using targeted search terms related to internal factors such as hydration status, hormonal regulation, and genetic variation, as well as external influences including ultraviolet radiation, air pollution, and light absorption. Eligible studies were full-text original articles in English or Indonesian that examined skin-active ingredients or physiological mechanisms affecting facial skin. The literature consistently identifies hydration as a fundamental determinant of skin elasticity, smoothness, and luminosity, mediated through corneocyte organization, lipid barrier integrity, and aquaporin-3–regulated water transport. Hormonal factors, particularly estrogen, play a critical role in maintaining dermal quality by stimulating collagen synthesis, enhancing skin thickness, and reducing oxidative damage. Genetic variability further contributes to individual differences in skin characteristics by influencing collagen density, antioxidant defense systems, pigmentation pathways, and inflammatory responses. External stressors significantly modulate these intrinsic processes, with ultraviolet radiation and air pollution accelerating skin aging through oxidative stress, collagen degradation, barrier disruption, and pigmentary alterations. In addition, light absorption and reflection at the skin surface, affected by sebum composition and optical properties of the stratum corneum, influence perceived skin tone and radiance. Collectively, the evidence underscores the importance of understanding how intrinsic and extrinsic factors interact to shape facial skin health. A holistic, evidence-based approach that integrates topical treatments with internal health optimization, hormonal balance, lifestyle modification, and personalized care strategies is essential for achieving and maintaining optimal facial skin condition.

Abstract

Proper skin hydration is essential for maintaining healthy skin and protecting it from environmental damage. A thorough understanding of the skin’s structure can help researchers identify its layers and components, leading to the development of effective skin hydration formulations. Emulsions are commonly used because they combine water and oil phases, along with ingredients that preserve hydration and enhance chemical penetration through the stratum corneum. Consequently, emulsions are prevalent in skincare and cosmetic products, which are often supplemented with humectants, occlusive agents, and emollients to enhance their efficacy. This study explores the mechanisms through which emulsions support skin hydration, focusing on the roles of water and oil in moisturizing and serving as a skin barrier, as well as the functions of humectants, occlusive agents, and emollients. In conclusion, the stratum corneum is critical for maintaining skin hydration by regulating the water and oil content within its cells and the lipid-rich intercellular spaces. Humectants, occlusive agents, and emollients each enhance hydration through unique mechanisms. We hope this article will assist researchers in developing highly effective, hydrating skincare and cosmetic products.
