Abstract

The skin is the largest organ on the human body that plays a vital role in protecting the body from environmental aggressions and maintaining internal balance, however, the natural aging process and exposure to external factors can cause various skin problems, including loss of elasticity, fine lines, and hyperpigmentation. To address these issues, the development of skincare products such as anti-aging gels is important. The aim of this study was to optimise the base of the anti-aging gel formulation by considering the selection of gelling agents with appropriate variations.The research method was conducted by obtaining five different formulas using a combination of gelling agents Carbopol and CMC Na with variations of Formula 1 which is 1% b/v carbopol with 2% b/v CMC Na, Formula 2 which is 1.25% b/v carbopol with 1.75% b/v CMC Na, Formula 3 which is 1.5% b/v carbopol with 1.5% b/v CMC Na, Formula 4 which is 1.75% b/v carbopol with 1.25% b/v CMC Na and Formula 5 which is 2% b/v carbopol with 1% b/v CMC Na . Physical testing was conducted to evaluate the formulation characteristics, including colourimetry, pH, viscosity, adhesion, and spreadability, comparisons between different formulas were conducted to determine the best base formula. The results showed that formula 5 with the ratio of gelling agent carbomer 2% b/v and CMC Na 1% b/v, is the optimal formula supported by physical testing, namely the metric choleretic test is good, homogeneous, pH 6.237 in accordance with the pH range of the skin, the Viscosity test has the highest viscosity of 148.34 d.Pas, the longest adhesion test with an adhesion time of 9.535 seconds, allowing the active substance to more easily penetrate the skin and be absorbed.

Abstract

The community empowerment program which focuses on innovation in processed fish products at the AB Banteng KKSS Palangkaraya Pool aims to overcome the problem of stunting among children by increasing nutritional intake. This initiative utilizes freshwater fish as an abundant source of local protein, by processing them into nutritious products such as nuggets, sausages and fish balls. The method used is the Asset-Based Community Development (ABCD) approach, which identifies and exploits local potential and involves the community in the entire production process. The program results show a significant reduction in the prevalence of stunting from 30% to 18%, an increase in children's daily protein intake from 35 grams to 60 grams, and an increase in average height of 2 cm. This program has also succeeded in increasing community skills and knowledge in fish processing, as well as providing economic benefits through job creation and increased income. Local government support to include processed fish products in school food programs also ensures the sustainability and expansion of program benefits. Challenges faced include changes in eating habits and environmental conditions, which are addressed through intensive nutritional education and pond management training.

Abstract

This community service activity aims to increase energy independence and agricultural productivity in the Harapan Farmer Group, Palangka Raya, through the application of solar panel-based agrivoltaic farming technology. Socialization and education were conducted to provide partners with an understanding of the agrivoltaic concept, which integrates agricultural production and renewable energy. Results showed a significant increase in partners' understanding of this technology. The selection of land for solar panel installation was based on stable sun exposure, so that the panels can function optimally without disrupting agricultural activities. The technology transfer process involved the installation of solar panels, the construction of greenhouses, and the application of supporting technologies such as sensor-based automatic irrigation systems. This technology has increased the efficiency of water and energy use, and created more stable farming conditions. Overall, the program succeeded in supporting energy security and agricultural productivity in peatlands, as well as having a positive impact on the welfare of farmers and environmental sustainability.

Abstract

Drymoglossum piloselloides is one of the epiphytic plants that is commonly found in Southeast Asia region. In this study, the ethanol extract of D. piloselloides plant has been used in the green synthesis of silver nanoparticles. The synthesized silver nanoparticles were characterized by ultraviolet-visible (UV-Vis) spectrophotometry, X-ray diffraction (XRD),Fourier-transform infrared (FTIR) spectroscopy, and transmission electron microscopy (TEM) measurements. The UV-Vis spectrum of silver nanoparticles showed a maximum wavelength at 453 nm. The XRD measurement showed the silver nanoparticles peaks at 38.38°, 44.60°, 64.76°, and 77.62°. The FTIR spectra provided evidence of the interaction between silver and chemicals in the plant extract as a weak signal at 682 cm-1. Meanwhile, TEM revealed an average size of 12.63nm. The synthesised silver nanoparticles were utilised for the reduction of 4-nitrophenol with a conversion percentage of up to 100% with a reduction reaction rate constant of 7.104 s-1. In addition, methylene blue was also successfully reduced with the synthesised silver nanoparticles as the catalyst with a reduction reaction rate constant (k) of 21.150 s-1. This study highlights the superior advantage of utilizing ethanolic extract of D. piloselloides to prepare silver nanoparticles with promising catalytic reduction purposes.

Abstract

Soothing gel is a new cosmetic preparation in society with physical properties that increase the acceptability and effectiveness of therapy. Karamunting (Melastoma malabatricum L.) is a plant that is widely known in the Central Kalimantan region. Karamunting flowers contain flavonoid, alkaloid and saponin. The flavonoid in karamunting can be used as antioxidants. The aim of this research is to formulate karamunting flower extract (Melastoma malabathricum L.) as a soothing gel and evaluate the physical properties. The formulation method used variations of carbopol and HPMC with an extract concentration of 5%. Phytochemical testing of the extract was carried out using a tube test and total flavonoid using UV-Vis. The physical properties of the gel were tested in the form of organoleptic, homogeneity, viscosity and adhesion tests. The total flavonoid yield of karamunting flower extract was 21.22% w/w. Organoleptic properties: odorless aroma, brownish red color, and cool sensation on the skin. The preparation is homogeneous and has a viscosity of 200-300 dpa's and an adhesive force of 10.50-21.24 seconds. So it can be concluded that shooting gel karamunting flower extract has good physical properties.

Abstract

Dragon scale (Drymoglossum piloselloides) leaf is a plant that contains secondary metabolites with antioxidant potential. This plant is known for its easy to grow nature and has a wide habitat distribution. The extraction method using acetone solvent has been proven effective in extracting secondary metabolites from this plant. To improve the extraction efficiency, this study used an optimization approach using the Central Composite Design (CCD) method. CCD involves three main factors in extraction experiments, namely solvent concentration, extraction time, and extraction temperature. Experiments were conducted with variations of these factors to find the optimal extraction conditions. The results of CCD method showed that the solvent concentration of 70%, extraction temperature at 52°C, and extraction time of 60 minutes. Statistical analysis showed that the model used was significant, with an F-value of 9.20 and a P-value less than 0.01159, indicating that the factors tested had a significant effect on the extraction results. The results of this study have great potential in maximizing the use of dragon scale leaves as a source of antioxidant secondary metabolites.

Abstract

This study aims to assess the effect of planting media on pakchoi (Brassica rapa L.) growth. The research was conducted at Pak Slamet's Cipta Rasa Fruit Farm in October 2024. Each treatment used different planting media, with hydroponics supplemented with AB mix nutrients and KOHE without additional nutrients. The results showed that variations in growing media and nutrient supplementation had a significant impact on plant growth. The NFT hydroponic system gave the best results, with pakcoy reaching an average plant height (6.5 cm), number of leaves (8 leaves), and leaf width (5.8 cm) at 3-4 weeks after transplanting (HST) The results of plant height, number, and width of leaves from KOHE are listed. The provision of nutrients shows that the right amount and concentration can increase the overall growth of pakcoy.
