Abstract

This research investigates many factors that affect the quality of life of the elderly in Kampar Regency, Riau.  This research, with 402 people aged 60 and above, indicated that the elderly's perception of their own health is the most significant predictor of their overall health-related quality of life.  Social support—assistance from family, friends, and the community has been shown to be very impactful, highlighting the significance of social connections for well-being in later life.  Leisure activities —spanning from morning walks to engaging in religious practices or gardening—substantially enhance well-being. Interestingly, the elderly's perception of justice in healthcare services also affects their quality of life. Elderly individuals who feel that access to healthcare services is distributed fairly tend to have a better quality of life. Meanwhile, aging does show negative effects, but this emphasizes the importance of programs that specifically target the needs of the elderly across various age groups, especially the very elderly. The utilization of community-based care services also plays an important role in improving the quality of life, demonstrating the value of a local support system that is easily accessible to the elderly. These findings provide a comprehensive picture of what is truly important for the elderly in Kampar Regency, and can serve as a foundation for the development of more effective programs to enhance well-being in old age.

Abstract

Ficus rasemosa L. (FR), commonly known as a fig tree in Asia, is traditionally consumed in Lombok and recognized for its medicinal due to its phenolic compounds, as general bioactive compounds FR contain, have benefits such as being antidiabetic properties. Despite its ethnobotanical significance, limited studies have explored the development of FR fruits as a functional herbal tea, particularly concerning processing variables such as drying temperatures. This study evaluated the effects of three drying temperatures—50 oC (T1), 60 oC (T2), and 70 oC (T3)—on the total flavonoid content (TFC), total phenolic content (TPC), antioxidant activity (DPPH free radical scavenging assay), and organoleptic properties of FR herbal tea. The TFC, TPC, and DPPH assay were quantified using UV-VIS spectrophotometry. The highest TFC (1.96 g QE/g) and TPC (0.36 g GAE/g) were observed at 50 oC, while the strongest antioxidant activity with the lowest IC50 of 192.27 ppm occurred at 60 oC. Sensory evaluation showed the teas dried at 60 and 70oC were more acceptable, particularly in terms of color and overall preference. These results suggest that drying at 60 oC offers an optimal balance between phytochemical, antioxidant activity, and sensory quality, highlighting the potential of RF fruit as functional herbal tea.

Abstract

Reduced graphene oxide (rGO) has been chemically synthesized from graphite powder. Graphite powder is oxidized using a strong oxidizing compound to obtain graphite oxide, this process is called the Hummer Method. Graphite oxide is dispersed using an ultrasonic vibrator to peel off the graphite oxide layer and become graphene oxide. The epoxy group in graphite oxide is reduced using 80 wt% hydrazine compound at temperatures of 70????, 80 and 90????C to obtain reduced graphene oxide. Then rGO is characterized using Uv-Vis spectroscopy, and FTIR. The Uv-Vis spectrum shows that the absorbance of rGO decreases with increasing reduction temperature. Then the absorbance data is calculated for its optical constant using the Kramers-Kronig Method. The refractive index values ​​of the real and imaginary parts of the calculation results show that in the low energy region an increase in the optical constant value is obtained with the addition of rGO. Then rGO was used in supercapacitor fabrication using PVA as a binder, 1 M ????2????????4 electrolyte, and aluminum foil as a collector and the supercapacitor mass was obtained as much as 0.01 grams. From the cyclic voltammetry measurement, the capacitor capacitance value was obtained as much as 24.5 F/gr.

Abstract

This study aimed to evaluate the phytochemical composition and antioxidant activity of five lichen species Cladonia portentosa, Cladonia rapii, Letharia vulpina, Parmotrema hypotropum, and Usnea trichodea collected from Sicike-Cike Nature Park, North Sumatra, Indonesia. Methanol extracts were prepared from dried and powdered lichen samples. Qualitative phytochemical screening using specific reagents identified the presence of alkaloids, flavonoids, tannins, saponins, terpenoids/steroids, and glycosides in varying levels among the species. Antioxidant activity was assessed using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method, with IC50 values ranging from 42.3244 µg/mL to 86.7479 µg/mL. Parmotrema hypotropum demonstrated the strongest antioxidant activity (IC50 = 42.3244 µg/mL), categorized as moderate based on literature benchmarks. The strong activity is likely due to the presence of alkaloids, flavonoids, and saponins. In contrast, Usnea trichodea showed the weakest activity. These results suggest that certain lichens, especially Parmotrema hypotropum, may serve as promising sources of natural antioxidants. The findings support potential applications in pharmaceutical formulations and natural cosmetic products, particularly those targeting oxidative stress. Future studies should focus on isolating dominant compounds such as usnic acid or flavonoid derivatives and further exploring their bioactivity profiles.

Abstract

Coffea arabica plantations in Central Sulawesi are carried out on the Napu highland, where this area is dominated by ultisol or yellow red podzolic soils, which have problems of high soil acidity and low availability of macro nutrients. This study used a completely randomised design method consisting of four treatments namely; without organic fertilisers (control)/P0, Leucaena leucocephala leaf compost 3 Kg/tree (P1), Samanea saman leaf compost 3 Kg/tree (P2), Tithonia diversifolia leaf compost 3 Kg/tree (P3), Cow and goat manuire 3kg/tree (P4). The results showed that there were 10 species of Arbuscular Mycorrhizal Fungi (AMF) associated with Coffea arabica plants namely Glomus sp1, Glomus sp2, Glomus sp3, Glomus sp4, Acaulospora sp1, Acaulospora sp2, Acaulospora sp3, Gigaspora sp1, Gigaspora sp2 and Gigaspora sp3. Furthermore, the higher density of FMA spores was found in the treatment without organic fertiliser application/control (P0) which was 31 spores/10 g soil, compared to the treatment of Tithonia diversifolia leaf compost treatment (P3) with 11 spores/10 g soil, cow and goat manure treatment (P4) with 3 spores/10 g soil, and Samanea saman leaf compost treatment (P2) with 2 spores/10 g soil.  And in the Leucaena leucocephala leaf compost treatment (P1), no AMF spores were found. The difference in AMF spore density in the various organic fertiliser treatments mentioned above is related to the effect of improving soil chemical properties on the soil. The results of this study contribute to the understanding of the importance of soil amendments with organic fertilisers for the improvement of organic and sustainable arabica coffee production in the future.

Abstract

The lack of maximum use of learning media due to the limited ability of teachers in creating learning media resulted in students being bored and unfocused, resulting in 17 students out of 27 fourth grade students of SD Bumiayu 01 Pati Regency scoring incomplete on IPAS subjects. This is the background for researchers to create scrapbook learning media as a media tool in learning with the hope of overcoming the problems that occur. Scrapbooks are books with attractive images that are tailored to the subject matter and can be accessed flexibly. The validity test results received a score of 84% by media experts and 93% from material experts. From the results of data analysis obtained, this scrapbook learning media proved to be effective in improving learning outcomes. This statement is evidenced by the acquisition of the paired sample t-test value of 0.00 which means <0.05, meaning that there is a difference in the average pretest and posttest scores. In the N-Gain test getting a value of 0.6291 medium category. So it is concluded that there is an increase in the average IPAS score from 50.8 to 80.5 by students after using the media implemented in learning.
