Mochamad Arviansyah
The controversy surrounding the halal status of the AstraZeneca COVID-19 vaccine, combined with the urgency of pandemic control efforts, has raised concerns among Muslim communities, particularly in rural settings. This study examines the effects of halal awareness, perceived emergency conditions, and religiosity on individuals’ decisions to receive the AstraZeneca vaccine in Kaliombo Village, Bojonegoro Regency. A quantitative survey involving 112 respondents was analyzed using multiple regression, t-tests, F-tests, and Moderated Regression Analysis (MRA). The results show that halal awareness has a statistically significant direct effect on vaccination decisions (t = 2.227, p = 0.028), whereas perceived emergency conditions do not (t = 1.803, p = 0.074). Together, halal awareness and emergency conditions significantly influence vaccination decisions (F = 9.253, p < 0.001), though their explanatory power remains modest (R² = 0.145). Religiosity does not moderate these relationships but functions as an independent predictor (t = 2.653, p = 0.009), increasing the explained variance to 17.5% (R² = 0.175). While statistically significant, these effects are substantively modest, indicating that behavioral decisions are shaped by multiple social and contextual factors. Overall, the findings highlight the prominent role of halal awareness and religiosity in vaccine acceptance and underscore the need to integrate religious considerations into public health communication strategies.

Women in rural areas continue to face limited access to education and economic opportunities, which prevents their potential from being fully developed. This study analyzes women’s empowerment through the local economic initiative Kelompok Usaha Bersama (KUB) Batik Sekar in Putat Village, Purwodadi District, Grobogan Regency. A qualitative descriptive design was employed, using interviews, observations, and document analysis involving 20 female participants, local stakeholders, and government representatives. The findings show that the KUB Batik Sekar program enhances women’s skills in batik production, financial management, and marketing, which subsequently led to the formation of five new batik groups. Household income increased, reflected by an average percentage rise compared to the previous year. The empowerment process also strengthened women’s confidence, independence, and decision making roles within both the family and community. The proposed empowerment model emphasizes collaboration between skills training, organizational capacity building, and marketing network support. Although challenges remain, particularly in market competition and infrastructure, government and community support helps sustain the program. These findings demonstrate that women’s involvement in the local economy can improve welfare, drive social transformation, and preserve batik cultural heritage.

Ibrahim Khaleel Muazu, Aisha Balanmalam Nasir, Albashir Tahir
Depression is a prevalent and debilitating mental disorder that significantly affects global health and quality of life. Conventional pharmacological treatments have adverse effects, necessitating the search for alternative therapies. This study aimed to evaluate the potential antidepressant activity of the ethanol leaf extract of Guiera senegalensis in Wistar rats. Phytochemical screening was performed to identify bioactive compounds in the extract. Acute toxicity was assessed following OECD guidelines, with doses up to 5000 mg/kg. The antidepressant activity was evaluated using the Forced Swim Test (FST) and Tail Suspension Test (TST). Experimental groups received extract doses of 25, 50, and 100 mg/kg, with control groups receiving normal saline and reference groups treated with imipramine (10 mg/kg). Statistical analyses were conducted using one-way ANOVA with Dunnett’s post hoc test. Phytochemical analysis revealed the presence of flavonoids, tannins, and saponins, which are known for their neuropharmacological properties. Acute toxicity testing showed no mortality at 5000 mg/kg, indicating a high safety profile. Behavioral assessments demonstrated that the extract significantly reduced immobility time in the FST and TST at doses of 50 and 100 mg/kg (p < 0.05), suggesting antidepressant activity. The ethanol leaf extract of G. senegalensis exhibits both antidepressant effects in animal models, supporting its traditional use in managing mood disorders. The presence of bioactive compounds suggests a pharmacological basis for its efficacy. Further research is needed to elucidate its mechanisms of action and assess its long-term safety.

Effectiveness of Cattle Manure Compost in Supporting Growth and Productivity of Edamame (Glycine max L. Merril)
Sahfira Sahfira, Rinaldi Rinaldi
Edamame has strong market potential in Indonesia, but its development is constrained by reliance on chemical fertilizers that increase production costs and may reduce soil quality. Organic materials such as cattle manure compost offer a sustainable solution by improving soil fertility while supplying essential nutrients. This study aimed to evaluate the effects of different cattle manure compost application rates on the growth and yield of edamame. The experiment was conducted from February to May 2023 at the Teaching and Research Farm, Faculty of Agriculture, Jambi University, using a Randomized Complete Block Design (RCBD) with five treatments: 0, 5, 10, 15, and 20 tons per hectare, each replicated five times. The application of compost significantly increased the number of filled pods per plant, fresh pod weight, and total yield, with the highest yield recorded at 20 tons per hectare, representing a 28.9 percent increase compared to the control. However, compost application did not significantly affect vegetative growth parameters such as plant height and the number of branches, likely due to moderate nutrient content and slow nutrient mineralization. Overall, cattle manure compost at 20 tons per hectare improved edamame yield and offers a sustainable alternative to chemical fertilizers for enhancing soil fertility and productivity. These findings highlight the potential of organic amendments to support more environmentally friendly and cost-efficient edamame cultivation systems.
