Abstract

Hair loss is a common condition affecting both men and women and often diminishes quality of life. While synthetic agents like minoxidil are widely used to promote hair growth, their application is frequently associated with adverse side effects, highlighting the need for safer natural alternatives. This study aimed to evaluate the effectiveness of rosemary (Rosmarinus officinalis L.) extract in hair tonic preparations on hair growth and the product's physicochemical characteristics. Rosemary essential oil was extracted using steam distillation, then formulated into hair tonic at various concentrations (0%, 5%, 10%, and 15%), and compared with 2% minoxidil as a positive control. Physicochemical characterization included pH measurement, viscosity, and compound analysis using GC-MS. Hair growth activity was tested in vivo using male Wistar rats for 4 weeks, with hair length and weight as parameters. The results showed that all formulations had a pH of 4.18–4.75, corresponding to the physiological pH of the scalp. Viscosity increased with increasing rosemary extract concentration. GC-MS analysis revealed the presence of key compounds such as ?-myrcene, 1,8-cineole, and geraniol, which play a role in biological activity. In vivo testing showed that the 15% formulation produced the highest hair length (16.73 ± 1.97 mm), surpassing 2% minoxidil (10.02 ± 1.83 mm), while the 10% concentration produced the highest hair weight (87.083 ± 30.870 mg/cm²). Furthermore, no signs of irritation were observed in the rosemary group, while skin side effects were observed in the minoxidil group. It can be concluded that rosemary extract has the potential to be a natural active ingredient in an effective and safe hair tonic preparation to stimulate hair growth. A 10% concentration is recommended as the optimal formulation based on the balance between hair length and quality produced Contribution to Sustainable Development Goals (SDGs):SDG 3 – Good Health and Well-beingSDG 12 – Responsible Consumption and Production

Abstract

Palm oil-based flexible polyurethane foam has the potential to serve as a more environmentally friendly alternative material; however, further development is needed to meet consumer needs and compete with commercial products. This study aimed to evaluate the quality of palm oil-based flexible polyurethane foam using the Quality Function Deployment (QFD) method. The QFD analysis identified the foam’s ability to return to its original shape after deformation and resistance to pressure as the highest-priority consumer needs. These findings indicate that consumers expect foam with good elasticity, load-bearing capacity, and durability. The optimization of product formulation was identified as the primary technical strategy for addressing these consumer needs and improving the physical and mechanical properties of the foam. Therefore, formulation optimization is essential for enhancing the quality and competitiveness of palm oil-based flexible polyurethane foam.

Abstract

The structural integrity of agricultural machinery is essential for ensuring safe and reliable operation under service loading conditions. Although the performance of the authors' previously developed solar-powered maize sheller has been experimentally evaluated, the structural behavior of its supporting frame has not yet been investigated. Therefore, this study aims to evaluate the supporting frame's structural performance using the Finite Element Analysis (FEA) method. A three-dimensional numerical model of the frame was developed in SolidWorks Simulation based on the fabricated prototype. The supporting frame was modeled using beam elements, while commercial machine components, including the photovoltaic panel, hopper assembly, shelling cylinder assembly, electric motor, battery, inverter, and solar charge controller, were represented by equivalent static loads applied at their actual mounting locations. The finite element model considered the self-weight of the installed machine components under static operating conditions. The simulation results indicate that the maximum equivalent Von Mises stress developed in the frame is 12 MPa, which is substantially lower than the yield strength of the structural material (221 MPa). The maximum total deformation is 0.20 mm, while the minimum factor of safety reaches 19, indicating that the supporting frame possesses a considerable structural safety margin. These findings demonstrate that the proposed frame design is structurally adequate to support all installed machine components without exceeding the allowable material strength. Furthermore, the developed numerical modeling approach provides an efficient and practical framework for evaluating and optimizing the structural performance of agricultural machinery during the design stage before prototype modification or experimental structural testing.

Abstract

Peat water is a potential alternative water resource in Indonesia, particularly in the peatlands of Sumatra and Kalimantan. However, its high acidity and elevated concentrations of natural organic matter (NOM) prevent its direct use as drinking water. Since the physicochemical characteristics of peat water vary among regions, chemical dosage requirements and ionic behavior may differ under identical operating conditions. Therefore, as a preliminary optimization phase, this study comparatively evaluated the coagulation–flocculation performance of peat water collected from Sumatra and Kalimantan using the Jar Test method. Polyaluminium chloride (PAC) was employed as the primary coagulant, while burnt lime (CaO) and hydrated lime (Ca(OH)?) were evaluated as alkaline agents. Treatment performance was assessed based on initial baseline ionic responses, including pH, total dissolved solids (TDS), and electrical conductivity (EC). Statistical analyses were performed using two-way analysis of variance (ANOVA) followed by Tukey's honestly significant difference (HSD) test at a 95% confidence level. The results showed that sampling location, chemical treatment, and their interaction significantly affected all measured parameters (p < 0.001). Hydrated lime combined with PAC effectively increased pH, whereas TDS and EC responses varied according to treatment dosage and peat water origin. Among the evaluated treatments, HL200-PAC80 produced pH values closest to the Indonesian drinking water standard, whereas HL200-PAC20 applied to Kalimantan peat water resulted in the lowest residual TDS and EC. These findings demonstrate that regional variations in peat water characteristics strongly influence coagulation–flocculation performance, providing a foundational basis for site-specific dosage optimization prior to main-stage NOM and color removal processes.

Abstract

Excessive heat accumulation in photovoltaic panels increases operating temperature and reduces electrical performance, particularly in tropical regions. Shape-stabilized phase change material (SSPCM) offers a passive thermal management approach by absorbing excess heat as latent heat while maintaining dimensional stability through a supporting matrix. This study evaluates the effect of SSPCM integration on photovoltaic performance compared with a reference panel without SSPCM, and compares lauric acid- and paraffin wax-based SSPCMs using activated fly ash (AFA) as the supporting matrix. Both SSPCMs were evaluated through leakage test, Differential scanning calorimetry (DSC), and outdoor solar panel performance testing. The optimum lauric acid formulation was a 45:55 lauric acid-to-AFA ratio, with the lowest leakage rate (0.043%) and the highest latent heat (56.21 J/g). Under representative outdoor test conditions, this formulation reduced the solar panel temperature by 2.72 °C and increased efficiency by 1.76 percentage points. For the paraffin wax system, the optimum formulation was obtained at a 40:60 paraffin wax-to-AFA ratio, with a mass loss of 1.82% and a latent heat of 53.78 J/g. Under the same representative test conditions, this formulation reduced the solar panel temperature by 3.29 °C and increased efficiency by 1.88 percentage points. Across five outdoor testing sessions, LA-SSPCM and PW-SSPCM reduced the average PV temperature by 2.44 and 2.62 °C, respectively, and increased electrical efficiency by 2.53 and 1.65 percentage points, respectively. The results confirm that SSPCM integration improves photovoltaic performance. LA-SSPCM showed lower leakage rate, slightly higher latent heat, and superior electrical efficiency improvement, while PW-SSPCM provided a slightly greater average temperature reduction, although the difference in average temperature between the two SSPCMs was not statistically significant.

Abstract

Cadmium (Cd) pollution in water bodies requires effective treatment methods that utilize sustainable alternative materials. This study aims to analyse the efficiency of Cd removal using sulfur-modified activated carbon derived from wastewater treatment plant (WWTP) sludge at varying contact times and to analyse its adsorption kinetics. We converted wastewater treatment plant (WWTP) sludge into activated carbon via KOH activation and Na?S sulfurization. We conducted batch adsorption experiments at different contact times to evaluate Cd removal. Cd(II) removal reached 92.37% within 90 min (initial concentration: 20.32 mg/L, dosage: 2.5 g/L). The removal efficiency increased with contact time and remained relatively stable after 90 min, indicating that adsorption equilibrium had been achieved. Adsorption kinetics followed the pseudo-second-order model (R² = 0.9845), indicating chemisorption driven by sulfur surface sites. Sulfurization modified the chemical properties of the activated carbon surface and enhanced its affinity for Cd. These findings demonstrate the potential of sulfur-modified activated carbon derived from WWTP sludge as a sustainable adsorbent for Cd-contaminated water.

Abstract

Indonesia relies heavily on importing commercial seaweed nori, reaching 321 tons annually. To reduce import dependency and utilize local botanical resources, water clover (Marsilea crenata), an endemic bioactive-rich fern from East Java, represents a promising alternative raw material. This study aimed to characterize the physicochemical and mechanical properties of artificial nori made from water clover leaves with varying carrageenan concentrations (1%, 1.5%, and 2%). The resulting sheets were analyzed for yield, moisture, ash, protein, crude fiber, total phenolic content, antioxidant activity, tensile strength, and thickness. Results indicated that higher carrageenan concentrations increased yield, moisture, ash, crude fiber, thickness, and tensile strength due to the internal bonds between carrageenan. Conversely, total phenolic content and antioxidant activity decreased because bioactive compounds were less extractable due to entrapment within the matrix. This research requires further optimization to match the mechanical tensile strength of commercial seaweed-based nori.

Abstract

Crystal violet (CV) is a cationic dye widely used in various industrial applications, and its presence in the environment poses a potential risk to water quality. This study aimed to optimize the CV adsorption capability of a Black Soldier Fly pupae-modified avocado seed adsorbent (AS-BSF) using a Response Surface Methodology (RSM) with a Box-Behnken design (BBD). The quadratic model was statistically significant (p < 0.0001), with an R2 of 0.9070 and an adjusted R2 of 0.8139. Initial CV concentration and solution pH were significant linear factors, while all quadratic terms also showed significant effects on adsorption capacity. The optimum conditions predicted by the model were pH 7.75, initial concentration of 1522.38 mg L-1, contact time of 46.83 min, and heating adsorbent of 47.93°C, yielding a predicted adsorption capacity of 166.916 mg g-1 and a desirability value of 0.874. Experimental validation under the optimized conditions yielded an adsorption capacity of 169.114 mg g-1. These results demonstrate that RSM-BBD is effective for modeling and optimizing the CV adsorption capacity of the AS-BSF adsorbent.

Abstract

Used frying oil undergoes quality deterioration due to hydrolysis, oxidation, and polymerization during repeated heating, necessitating regeneration to improve its quality. Red ginger (Zingiber officinale var. rubrum) powder has potential as a natural bioadsorbent due to its porous structure, lignocellulosic components, and antioxidant compounds. This study aimed to evaluate the effects of red ginger powder concentration and immersion time on the physicochemical and organoleptic characteristics of regenerated palm cooking oil and to determine the best treatment. The study employed a factorial Completely Randomized Design with two factors: red ginger powder concentration (5%, 10%, and 15% w/v) and immersion time (12, 24, and 36 h), with two replications. Data were analyzed using analysis of variance (ANOVA), followed by Duncan’s multiple range test at a 95% confidence level. The results showed that red ginger powder concentration and immersion time significantly affected the observed parameters (p ? 0.05). The best treatment was obtained using 15% w/v red ginger powder with 36 h immersion, resulting in a free fatty acid content of 0.3539%, peroxide value of 2.3333 mEq O?/kg, iodine value of 20.2665 mg/g, smoke point of 183.5°C, and viscosity of 68.00 mPa·s, with improved organoleptic color and aroma characteristics. The regeneration process improved the overall quality of used frying oil; however, the resulting moisture and free fatty acid contents did not fully meet the requirements of SNI 7709:2019. The findings demonstrate the potential of red ginger powder as a natural bioadsorbent for regenerating used palm cooking oil.

Abstract

Jelly candy is a type of confectionery product that has a sweet taste and is typically consumed as a snack. The use of whole Eucheuma cottonii seaweed without added carrageenan was chosen because this study focuses on the development of functional food-based jelly candy products. This study aims to determine the effect of the proportions of E. cottonii seaweed puree and spirulina on the characteristics of the resulting jelly candy. This study used a completely randomized design (CRD) with two factors: Factor I, the proportion of E. cottonii seaweed puree (50:50, 60:40, 70:30), and Factor II, spirulina (0.5 g; 1 g; 1.5 g). The data obtained were analyzed using ANOVA, followed by a DMRT post-hoc test at the 5% significance level. The optimal formulation was achieved with a 70:30 ratio of E. cottonii seaweed puree to Spirulina platensis (1.5 g). This treatment produced jelly candy with a moisture content of 35.41%, ash content of 2.45%, crude fiber content of 1.13%, reducing sugar content of 4.16%, and a chewiness value of 52.03 N.
