This study aims to analyze the teaching materials for grade X physics from two important perspectives, namely the ESD (Education for Sustainable Development) pillar and the Science, Technology, Engineering, Art, and Mathematics (STEAM) approach. The research method uses descriptive qualitative research. The population in this study was teaching materials for grade X physics used by teachers in Rembang Regency. The research instrument was a checklist of analysis instruments based on indicators of the Education for Sustainable Development pillars and STEAM components to obtain data. The results of the study found that the teaching materials used had implemented the ESD and STEAM pillars with an average percentage of occurrence of 12% for the socio-cultural pillar, 36% for the environmental pillar, 16% for the economic pillar, 87% in the Science component, 50% in the technology component, 57% in the engineering component, 77% in art, and 40% in the mathematics component. The results show that the implementation of the pillars of ESD and STEAM pillars in teaching books was still low.

The quality of rivers and coastal is gradually deteriorating along with rapid population and socio-economic growth in the watershed to the estuary. Sampling was conducted in Semarang city rivers and Demak district rivers, Central Java Province, Indonesia, at four different stations according to geography and designation: river basins, estuaries, and rivers affected by industrial and domestic waste. Research time is August - October 2023 during the dry season. The research method uses descriptive analysis to determine the variables to be studied based on the research results in the field. River and coastal pollution levels are measured using the Heavy Metal Pollution Index method, with several water quality parameters measured, such as BOD, COD, Ammonia, TDS, TSS, and Total Coliform. In contrast, the heavy metal parameters measured are Cd, Ni, Zn, Cu, and Pb. The heavy metals and water quality parameters analyzed guided by Government Regulation of the Republic of Indonesia Number 22 of 2021 class 2. Water quality and heavy metal analysis use the Heavy Metals Pollution Index (HPI). HPI is an assessment method that shows the influence of individual heavy metal compounds on overall water quality. The results show that the status of non-metal water quality in terms of HPI analysis shows that Sampling Station (SS) 1 is 224.30 (unsuitable for drinking), SS 2 is 645.98 (unsuitable for drinking), SS 3 is 320.09 (unsuitable for drinking), SS 4 is 252.09 (unsuitable for drinking), and metal parameters in terms of HPI analysis show that SS1 is 26.43 (good), SS2 is 2345.84 (unsuitable for drinking), SS3 is 26.43 (good), and SS4 is 12.64 (excellent). The conclusions from these four research areas indicate that the status of water quality, according to the HPI is unsuitable for drinking, however, indications of heavy metals in 2 areas are still tolerable, namely good and excellent. The decline in water quality in the research area is caused by domestic and industrial waste polluting the waters. In conclusion, this river area requires further management from the collaboration of various stakeholders.Keywords:Water QualityHeavy MetalCoastalWatershed

Papaya leaves (Carica papaya L.) are known to contain bioactive compounds such as flavonoids, alkaloids, tannins, and saponins, which exhibit antiseptic, anti-inflammatory, antifungal, and antibacterial properties, making them promising for topical pharmaceutical preparations. However, achieving optimal physical characteristics in cream formulations requires careful selection and proportioning of emulsifiers. This study investigates the effect of varying ratios of stearic acid and triethanolamine on the physical properties of creams containing ethanol-extracted papaya leaf extract. The extract was obtained via maceration using 96% ethanol and confirmed to contain active compounds through phytochemical screening and thin-layer chromatography. Eight formulations were developed using a Simplex Lattice Design (SLD) with stearic acid concentrations ranging from 15–17% and triethanolamine from 2–4%. Physical evaluations included tests for pH, viscosity, adhesion, and spreadability. All formulations met standard of cream quality requirements, but the optimal formula was identified at 15.20% stearic acid and 3.79% triethanolamine, offering the most desirable physical characteristics. This formulation strategy demonstrates the potential for producing effective and stable papaya leaf creams, with implications for natural-based dermatological product development.

Many things from the life sector have used the existence of technology. Where a technology is able to help various problems in various fields such as livestock and agriculture. Computers have been included in it as a tool to do a job or identify existing problems. However, sometimes as a practitioner in the field of animal husbandry, especially qurban animals, they come to the conclusion that it is often found that sacrificial animals in the market that want to be sacrificed do not meet the requirements both in syari ah (law) and health. With the application of determining the feasibility of sacrificial animals according to the Syariah using the web-based Simple Additive Weighting (SAW) method. This system is later expected to be able to determine whether or not a sacrificial animal will be sacrificed so that the community or people who sacrifice are not harmed and the reward for the sacrifice is perfect.

Patchouli leaves (Pogostemon cablin) are known to contain flavonoid compounds with potential antioxidant properties. However, comparative data on flavonoid content and antioxidant activity across different extract fractions of patchouli leaves remain limited. To address this gap, the present study was conducted to analyze the total flavonoid content and evaluate the antioxidant activity of the ethanol extract and three solvent fractions—n-hexane, ethyl acetate, and wáter using the DPPH method as an indicator of free radical scavenging activity. The extraction was carried out through maceration, followed by fractionation. The determination of flavonoid content employed a colorimetric method based on the aluminum chloride reaction, while antioxidant activity was assessed using the DPPH assay. The results revealed that the ethyl acetate fraction contained the highest flavonoid concentration (1.615 ± 0.0591%) and exhibited very strong antioxidant activity, with an IC₅₀ value of 17.3909 ± 0.1327 μg/mL. These findings suggest that the ethyl acetate fraction holds significant potential as a natural antioxidant agent, with possible applications in the pharmaceutical field or nutraceutical-based health products.

Spirulina platensis is a blue-green microalga known for its antibacterial properties, offering potential as a natural alternative in acne treatment. Acne vulgaris, often caused by Staphylococcus epidermidis, requires effective topical solutions. Gels are favored for their non-greasy texture, ease of application, and good skin absorption. This study aimed to formulate and evaluate anti-acne gels containing 25% Spirulina extract with varying Carbopol concentrations (0.5%, 1%, 1.5%). Each formulation was assessed for physical properties, stability over 21 days, and antibacterial activity against S. epidermidis. All gel formulations met quality standards for pH, homogeneity, viscosity, spreadability, and adhesiveness. The gel with 0.5% Carbopol (FI) showed the best spreadability, ideal viscosity, and good adhesiveness, along with the highest antibacterial activity, exhibiting an inhibition zone of 16.5 mm—comparable to tetracycline. In conclusion, Spirulina-based gel with 0.5% Carbopol offers an effective, stable, and natural anti-acne option. These findings highlight the potential of Spirulina as a bioactive agent in topical formulations and encourage further research for clinical applications in acne management.
