This study aims to compare the level of carbon monoxide (CO) air quality in Green Open Space (GOS) and Non-Green Open Space (NGOS) along the Abepura–Sentani main road in Jayapura City. The research was conducted in two locations: the Taman Makam Pahlawan Denzipur Waena (GOS) and the front area of Mega Waena (NGOS). CO levels were measured using a CO smart sensor over a period of one week, with measurements taken in the morning, noon, and afternoon at six sampling points. The findings indicate that CO concentrations are significantly lower in GOS areas compared to NGOS areas. The presence of vegetation in GOS helps reduce CO pollution by acting as a natural filter. These results highlight the importance of maintaining and developing green open spaces in urban areas as part of efforts to reduce air pollution and improve public health.

Background: Premenstrual Syndrome (PMS) is a combination of physical, emotional, and behavioral symptoms that occur cyclically before menstruation and are commonly experienced by adolescent girls. Common symptoms include fatigue, abdominal pain, headaches, anxiety, and mood disturbances, which can affect sleep quality, concentration, and academic productivity. This article provides an in-depth examination of the definition, types, prevalence, causes, impacts, and management of PMS in adolescent girls. Based on epidemiological data, the prevalence of PMS is quite high, both globally and nationally, with incidence rates in Indonesia reaching 70–90% among women of reproductive age, and most cases beginning during adolescence. There are four main types of PMS: Type A (anxiety), Type H (hyperhidrosis), Type C (food cravings), and Type D (depression), each with specific characteristics and etiologies. Causes of PMS include hormonal imbalances of estrogen and progesterone, reduced serotonin levels, poor sleep quality, psychological stress, genetic factors, and unhealthy lifestyles. The impact of PMS on adolescents is complex, including decreased academic performance, social relationship disturbances, and reduced psychological well-being. Therefore, PMS management should be approached holistically through pharmacological (such as NSAIDs, antidepressants, and diuretics) and non-pharmacological (physical exercise, relaxation, lifestyle changes, and nutritional education) interventions. Environmental support and reproductive health education are crucial to help adolescents effectively manage PMS symptoms and improve their quality of life. This study is expected to serve as a foundation for promotive and preventive interventions in adolescent health care.

This study aims to evaluate the lightfastness of organic ink formulated from purple sweet potato (Ipomoea batatas L.) pigment for screen-printing applications on 24s cotton combed fabric. The ink formulations varied the pigment amount (10, 15, and 20 grams) and solvent volume (distilled water) of 25 and 30 mL, while the binder and thickener components were kept constant. Lightfastness was assessed by measuring the change in lightness (ΔL*) before and after 24 hours of light exposure. The results showed that the formulation containing 15 g of pigment and 25 mL of solvent (P2A1) exhibited the best colorfastness, with an average ΔL* of 0.23, while the formulation with 10 g pigment and 25 mL solvent (P1A1) showed the poorest performance (average ΔL* of 1.86). A lower solvent volume resulted in higher resistance to light exposure. Moreover, using either too little or too much pigment negatively affected ink transfer and reduced lightfastness. Two-way ANOVA on log-transformed data revealed that the interaction between pigment concentration and solvent volume had a significant effect on ΔL* (p < 0.001), contributing 72.8% to the total data variation. This study confirms that achieving an optimal balance between pigment amount and solvent volume is crucial for producing organic ink with good lightfastness

Education is not only about academic knowledge, but also about the overall balance between body and mind. Amidst increasing academic demands and constant social pressures, students’ mental health is a crucial aspect that should not be ignored. Mental health literacy in a legal perspective is the foundation for academic success, healthy social interactions and overall quality of life. In the educational environment, we often talk about achievement, grades and preparation for the future, but we often forget that students’ mental health is an important foundation for achieving such success. Mental health disorders such as anxiety, depression or stress that are not addressed can interfere with concentration in learning, healthy social interactions, and even general physical health. Therefore, it is important for us to start building mental health literacy in a legal perspective among students. By knowing the symptoms that may appear, preventive measures that can be taken and available sources of support, we can help create an inclusive, caring and supportive educational environment for students’ mental well-being. Many countries have specific regulations that cover aspects of mental health literacy in the educational environment, including students’ rights related to access to services and protection from discrimination. Student mental health literacy from a legal perspective involves the application of legal principles in the context of protecting and fulfilling students' rights related to mental health in the educational environment. Mental health literacy from a legal perspective as an integral part of individual well-being is gaining increasing emphasis in the legal realm. Protection of individual mental health does not only rely on medical aspects, but is also closely intertwined with the rights and regulations that accompany it. Education, advocacy, and cross-sector collaboration are key in efforts to improve mental health protection from a legal perspective that includes interrelated social, educational, health, and legal aspects. Through a better understanding of this background, regulations and policies can be developed to better protect and support students' mental health in educational institutions.    

The processing of natural fibers as raw materials for paper has grown over the past few years. However, the use of composite paper as a printing substrate has several drawbacks. One of them is the low color reproduction quality of printed images on paper made from natural fibers, caused by the insufficient whiteness of the paper. This study aims to investigate the effect of titanium dioxide (TiO₂) addition on the color reproduction quality of composite paper based on sugarcane bagasse fiber. TiO₂ was varied at concentrations of 0%, 10%, and 20%. Printing process was carried out using an inkjet printer with standard CMYK and RGB color patches. After that, the printed results were measured using colorimeter with D65 illuminant. Color distribution analysis was processed using MATLAB software. The results showed that the addition of TiO₂ increased the whiteness of the paper, as indicated by the higher L* values. The color gamut visualization demonstrated that the gamut area expanded as the TiO₂ content increased. This result shows that the addition of TiO₂ affects the color reproduction quality of composite paper.

Background: Research of glucose detection is important in diabetes management and biosensor development. Taking into account the large amount of water retention, the biocompatibility of hydrogels makes them ideal candidates for glucose detection. The PBA groups, when grafted to hydrogel matrices, improve the glucose-related response of the hydrogels significantly. Objective: To create a novel PBA (phenylboronic acid) holographic glucose sensor, MAAm-co-4VPBA, for uninterrupted monitoring of blood glucose levels, which demonstrates the first successful glucose measurement in whole blood using PBA sensors. Methods: Methylacrylamide (MAAm) was copolymerized with 4-vinyl phenyl boronic acid (4-VPBA) by means of free radical polymerization employing 1,6-hexanedioldiacrylate (HDODA) as a crosslinker and the photoinitiator 1-hydroxycyclohexyl phenyl ketone. The responsive glucose behavior of the resulting polymer was characterized in terms of swelling dynamics, ex vivo flow tests, and error grid analysis mechanisms. Results: The MAAm-co-4VPBA polymer exhibits reversible glucose binding via PBA-diol interactions that allow complexation at different pH and concentration levels. Modulation of the responsive elements of the microcapsules by hydrophobic PBA and hydrophilic MAAm units yields maximum swelling and shrinking dynamics at 37 trail degrees. The sensor successfully detected glucose in opaque biological fluids, blood plasma, without any interference from antibiotics or other therapeutics or endogenous compounds. Ex vivo tests showed real-time glucose monitoring without hysteresis. Most importantly, this work is the first to report the use of PBA-based sensors in whole blood for measuring glucose. Conclusion: The MAAm-co-4VPBA holographic sensor possesses outstanding features such as accurate records and strong resistance to chemicals and slow response to detection, confirming its effectiveness in continuous glucose monitoring. Moreover, the ability to operate in the real world enables the aid in clinical diagnosis of diabetes.

This study aims to analyze the impact of general allocation funds, agglomeration, and human development index on regional inequality in Eastern Indonesia during the period 2019–2023. Regional inequality remains a crucial issue in Indonesia's development agenda, especially in the eastern region, which has experienced slower growth and uneven provision of public services. This study uses panel data regression analysis with secondary data. The results indicate that general allocation funds and the human development index have a significant negative impact on regional inequality, suggesting that increased fund transfers and improvements in human development can reduce inequality. Conversely, agglomeration has a significant positive impact, suggesting that economic concentration can widen disparities between regions.

Mercury is a highly toxic and bioaccumulative heavy metal. Despite its prohibition, mercury is still frequently found as a contaminant in cosmetic products, particularly in whitening products. This article aims to review and present various findings from previous studies on mercury levels in cosmetic preparations marketed in Indonesia, analyzed using the Atomic Absorption Spectrophotometry (AAS). The method employed is a literature review of scientific articles published between 2015 and 2025, selected based on their focus on mercury analysis in cosmetics use of the AAS method. The review results show that the majority of whitening creams and lotions contain mercury levels exceeding the safety limits set by the Indonesian National Agency of Drug and Food Control (BPOM RI), with some samples showing extremely high concentrations reaching thousands of ppm. In contrast, other preparations such as powders, hair dyes, and deodorants generally have low or undetectable mercury levels. These findings indicate a lack of understanding regarding mercury and its dangers, especially regarding compliance with regulations on cosmetic products, especially those sold online. The conclusion of this review emphasizes the need for enhanced regulatory enforcement, stricter supervision, and increased public education to protect consumers from the health risks posed by mercury-containing cosmetics.

This study aims to determine how nano chitosan is produced through the ionic gelation method. The process of making nano chitosan is carried out using variations in chitosan concentrations of 1%, 5%, and 10%, and using a magnetic stirrer. Morphological tests were carried out using Scanning Electron Microscopy (SEM) to observe the shape and size of the particles formed. The addition of TPP (Trisodium Tripolyphosphate) as a crosslinker and certain surfactants are used to increase particle stability. Treatment for ±2 hours showed optimal results in terms of a more homogeneous particle size distribution. Based on the results of SEM observations, it is known that increasing the concentration and time settings and the use of appropriate surfactants can reduce wrinkles in nano chitosan particles. The particle size obtained is in the range of 278–350 nm. Thus, the ionic gelation method has proven effective in producing uniform nano chitosan and has good morphology for further applications.

Red roses (Rosa damascena Mill.) are known to contain active compounds such as flavonoids, tannins, and vitamin C, which have potential antioxidant and anti-inflammatory properties. However, the utilization of rose flower waste after extraction remains limited. This study aims to formulate and evaluate gel preparations based on red rose extract and post-extraction rose flower waste as an innovation in natural-based topical formulations. This research is an experimental laboratory study using a post-test only design. Three concentration variations were formulated for both the extract (F1, F2, F3) and rose flower waste (F4, F5, F6) using HPMC as the gel base. Physical evaluations included organoleptic testing, homogeneity, pH, adhesion, spreadability, and viscosity. Data were analyzed descriptively and statistically using the Kruskal–Wallis test to determine the effect of concentration variation on physical parameters. All formulations showed good organoleptic and homogeneity results. The pH values were within the safe range for skin (4.75–5.92). Adhesion times met the criteria of >1 second, with a tendency to increase alongside higher concentrations of active ingredients. Spreadability fell within the acceptable range (3–5 cm), decreasing as viscosity increased. The viscosity values ranged from 20,150 to 20,182 cps. There was a significant effect of concentration variation on pH (p < 0.05), adhesion in extract-based gels (p = 0.021), and spreadability in waste-based gels (p = 0.024). In conclusion, gel preparations made from red rose extract and its waste can be successfully formulated with good physical stability and meet standard criteria for topical formulations. Rose flower waste has potential as an alternative active ingredient in the development of natural-based gel products.

This study analyzes the patterns and dynamics of income inequality across districts and municipalities in Aceh Province during the 2022–2024 period using data from the National Socio-Economic Survey (Susenas) published by Statistics Indonesia (BPS). A descriptive-comparative approach was employed with the Gini Ratio as the main indicator to examine spatial variations and inequality trends between urban and rural areas. The results show that Aceh’s Gini Ratio declined from 0.296 in 2022 to 0.294 in 2024, indicating a modest improvement in income distribution. The reduction in inequality mainly occurred in rural areas, while urban regions experienced a slight increase due to the concentration of economic activities among higher-income groups. Banda Aceh and Lhokseumawe recorded the highest inequality levels, whereas Aceh Tengah and Bireuen demonstrated relatively strong income equality. Overall, Aceh remains one of the provinces with low-income inequality in Indonesia but still faces challenges of structural disparities across regions. The findings highlight the need to shift policy orientation from redistributive equality toward productivity-based equality through regional economic integration, empowerment of micro and small enterprises, and the development of inclusive economic sectors to achieve equitable and sustainable growth..
