Abstract

ZnO dan Graphene Oxide merupakan material yang sangat menjanjikan dalam aplikasi solar cell. Kombinasi antara ZnO/Graphene Oxide memiliki kemampuan dalam mentranspor elektron dengan baik dibandingkan dengan ZnO atau Graphene Oxide saja. Namun, solar cell berbasis ZnO mudah terjadi rekombinasi pembawa muatan secara cepat karena energi band gap yang besar. Oleh karena itu, pembuatan komposit ZnO/Graphene Oxide yang diberi pengotor (doped) berupa urea dilakukan. Tujuan penelitian ini adalah untuk mengetahui pengaruh variasi jumlah doping urea pada komposit ZnO/Graphene Oxide terhadap karakteristik berupa struktur dan ukuran pada kristal dan partikel serta energi band gap yang nantinya akan dijadikan sebagai katalis solar cell. Tiga variasi jumlah doping yang diselidiki dalam penelitian ini: 0,11 gr, 0,22 gr, dan 0,33 gr dengan metode yang digunakan adalah metode sol-gel. Dari hasil analisis dapat dilihat bahwa dengan bertambahnya jumlah doping urea menunjukkan peningkatan pada ukuran partikel dari 107,86 nm menjadi 121,18 nm sedangkan pada ukuran kristal mengalami penurunan dari 46,39 nm menjadi 43 nm. Variasi jumlah doping urea juga mempengaruhi nilai energi band gap komposit ZnO/Graphene Oxide dengan nilai yang semakin menurun seiring bertambahnya jumlah doping yaitu dari 2,63 eV menjadi 2,57 eV, mengindikasikan peningkatan konduktivitas elektronik. Hasil ini menunjukkan bahwa komposit ZnO/Graphene Oxide dengan doping urea berpotensi sebagai katalis dalam aplikasi solar cell.

Abstract

Dadih or curd is a traditional product typical of West Sumatra which is made through natural fermentation using the lactobacillus plantarum bacteria in bamboo. Each region in West Sumatra makes curd in various ways that affect its quality. This study aims to determine the amino acid profile and antioxidant activity of curd from various regions in West Sumatra. The study was conducted by testing curd from 4 main curd center regions, namely Bukittinggi, Payakumbuh, Batusangkar and Alahan Panjang. Certain tests were applied to assess the protein content using the Kjedahl method, amino acids content using the HPLC method and antioxidant activity using the DPPH method. The test results showed that curd from Payakumbuh had a higher protein and amino acid content compared to other regions. Furthermore, such curd had the highest level of antioxidant activity towards free radicals compared to other regions, with an IC50 value of 95.11 ± 0.40 mg/kg, which was included in the strong category. There was a significant relationship between amino acid content and antioxidant activity of curd. It can be concluded that curd from Payakumbuh had the best amino acid content and antioxidant activity compared to other regions in West Sumatra.

Abstract

Art performances in schools can be carried out as an intracurricular part of cultural arts learning. On the other hand, art performances are also a forum for student creativity in various multi-event extracurricular activities with various targets. Of the many art performances that have been performed by students of SMA Negeri 1 Harau, both in music, dance, theater, and so on, the results of the performances achieved also vary in quality. However, the discussion of the quality of the performance results is more concentrated on the material issues of music, dance, theater, and so on. Even though the problem of the absence of performance room arrangement and audio equipment systems that meet the acoustic standards of art performances, is also a determining factor for the quality or not of art performances in schools. The results of monitoring since the survey, it is suspected that teachers do not have knowledge and technical skills about this problem, so the burden of the risk of art performances that are of low audio and acoustic quality, and have damaged the performance material itself, ultimately falls on students and audio/soundsystem equipment providers. The implication is that the quality of art performances in schools is not comparable to the waste of school budgets that have been provided for the procurement of an art performance.

Abstract

Background: Psychobiotics, including probiotics, prebiotics, and synbiotics, have been proposed to improve mental health through modulation of the gut–brain axis. However, findings from randomized controlled trials (RCTs) remain inconsistent, Objectives: To systematically review and synthesize evidence on the effects of probiotics, prebiotics, and synbiotics on depression, stress, and mood in adult populations. Methods: A comprehensive search was conducted in PubMed, yielding 531 articles, of which 14 RCTs met the inclusion criteria. Risk of bias was assessed using the Cochrane Risk of Bias Tool. Meta-analyses were performed using both fixed- and random-effects models in RevMan. The study protocol was registered in PROSPERO (CRD420251103338). Discussions: Ten RCTs (n = 881) assessing depression did not show consistent benefits (SMD = –0.72; 95% CI: –1.42 to –0.01; p-value = 0.05; I² = 96%). Six RCTs (n = 444) evaluating stress also showed non-significant effects (MD = –1.35; 95% CI: –3.70 to 1.01; p-value = 0.26; I² = 73%). Conversely, six RCTs (n = 376) demonstrated significant improvements in mood (MD = 0.73; 95% CI: 0.25 to 1.20; p-value = 0.003; I² = 75%). Meta-regression indicated that larger sample sizes were associated with more consistent improvements in mood (p-value = 0.04). Sensitivity analyses confirmed the stability of the findings, and no evidence of publication bias was detected. Conclusions: Probiotic, prebiotic, and synbiotic supplementation may provide beneficial effects on mood and could serve as a potential nutritional intervention to enhance psychological health. However, effects on depression and stress inconsistent.

Abstract

Pumpkin bars are practical functional food products; however, their distribution is often hampered by a lack of data on quality degradation kinetics in the tripos environment. This study aimed to estimate the shelf life of pumpkin bars using the Accelerated Shelf Life Test (ASLT) method with the Arrhenius approach and to evaluate the effectiveness of aluminum foil packaging in maintaining product quality. This study used an experimental design conducted at the Food Laboratory of the Riau Ministry of Health Polytechnic and SIG Laboratory from January to October 2025. Samples were stored at 35, 40, and 45°C, and a control temperature of 18°C for 30 days, with observations every 7 days. The parameters observed included moisture content, water activity (Aw), and the presence of mold and yeast. Data analysis used the Arrhenius kinetic model to calculate the reaction rate constant and estimate the shelf life. The results showed that the product was stable in terms of mold and yeast <10 colonies/g. Increased moisture content (8.5–14%) and Aw (0.52–0.67) were the main limiting factors for the growth of these Based on Arrhenius calculations, the shelf life of the product was estimated to be 23–35 days at 35–45°C. Moisture content and sensory degradation were the main determinants of the shelf life of pumpkin bars in aluminum foil packaging.

Abstract

This study aims to strengthen evidence-based policymaking for stunting reduction in Pasaman Barat District, Indonesia, through a collaborative model linking academic institutions and with local government. A situation analysis was conducted to assess program coverage, implementation challenges, and multisectoral support related to stunting prevention. Quantitative data from 20 primary health centers showed that most specific nutrition intervention indicators below the national minimum target of 80%. A pilot strengthening program was then implemented, focusing on improving cadre capacity, service supervision, community engagement, and data management. Post-intervention results demonstrated statistically significant improvements in growth monitoring (54.49%±27.19 to 97.43%±5.26; p = 0.00), exclusive breastfeeding (19.04%±28.47 to 59.28%±37.38; p = 0.00), and iron–folic acid supplementation among pregnant women (22.28%±16.96 to 85.28%±24.62; p = 0.00). Other indicators, including complementary feeding practices, antenatal care visits, and adolescent anemia screening, showed numerical but non-significant changes. Qualitative findings further revealed challenges related to limited cadre skills, inadequate facilities, insufficient intersectoral coordination, low community participation, and inconsistent data quality. The developed collaboration model facilitated closer integration of research evidence into local decision-making and supported the formulation of strategic policy recommendations. Overall, the study highlights that institutionalized academic–government partnerships, combined with continuous monitoring and strengthened health system capacity, are essential to accelerate meaningful and sustained reductions in stunting in Pasaman Barat.
