This study aims to investigate the effects of tamarind leaf extract (Tamarindus indica L.) on neuropharmacological activity in mice using calculated percentages of responses based on the parameters PSM, SSSP, DSSP, SL, RO, SM, PSL, and ANA. This research was conducted as a laboratory experiment using a completely randomized design (CRD) with three treatment concentrations: 1%, 2%, and 4%. Observations were performed to assess the percentage of activity produced by each sample concentration, followed by descriptive–quantitative analysis to determine the dose–response pattern. The results showed that tamarind leaf extract produced varying responses across concentrations. The SSSP, ANA, and RO effects demonstrated increased activity at the 2% concentration, whereas other parameters (PSM, PSL, SM, SL, and DSSP) showed decreased activity. Interestingly, the SSSP parameter exhibited a positive dose–response pattern with the highest activity of 55.84% at 2%. Overall, the effectiveness of tamarind leaf extract depends on the concentration level. The 2% concentration appears to be the optimal dose for several neuropharmacological effects, while the 4% concentration was most effective only for SSSP. These findings highlight the importance of multi-concentration testing to determine effective dosing of natural products for biological applications and the need for further investigation.

Global economic developments show the acceleration of the adoption of circular business models, where resource efficiency and waste reduction are the main focuses to answer sustainability demands and SDGs targets. Although this trend is strengthening globally, MSMEs, especially those based on family businesses, are still lagging behind in their implementation, even though digitalization is increasingly opening up opportunities for operational optimization and innovation. The urgency of this research arises from the need to understand how the digital mindset and transformation of family business management can accelerate the readiness of MSMEs in implementing circular business practices. The novelty of this research lies in the integration of the three strategic concepts into a single analytical framework through the Systematic Literature Review (SLR), a perspective that has rarely been combined in previous studies. With the SLR method based on the PRISMA protocol, this study shows that MSMEs already have a strong foundation in the digital mindset, including technology readiness, innovation orientation, and adaptation of digital business models. Family business values have also been proven to support business continuity through knowledge transfer and long-term investment. However, the implementation of circular business practices is still weak, especially in resource cycle management, sustainable product design, and environmental impact measurement. The implication is that the synergy of digital mindset and family business governance can strengthen the transition of MSMEs to a circular economy that directly supports the achievement of the SDGs, especially in the areas of sustainable consumption-production and industrial innovation.

Food loss and food waste (FLW) constitute systemic challenges in modern food systems, with direct implications for resource efficiency, environmental sustainability, and food security, particularly in developing countries where horticultural food loss persists upstream while food waste increases in downstream tourism sectors. This review synthesizes literature from 2015 to 2025 on horticultural food loss, tourism-related food waste, and the role of universities in cross-sectoral FLW reduction, using Sembalun, West Nusa Tenggara, as an illustrative agrarian–tourism landscape. The review is based on a multi-database search of academic sources (ScienceDirect/Elsevier, SpringerLink, Wiley Online Library, Taylor & Francis Online, MDPI, and Emerald Insight), complemented by key policy documents from FAO, UNEP, and UNWTO. Thematic synthesis indicates that upstream food loss and downstream food waste reflect structural mismatches between local production systems, tourism consumption patterns, and food governance, and therefore cannot be effectively addressed through isolated sectoral or technical interventions. The review highlights universities as strategic knowledge brokers that facilitate penta-helix collaboration, generate empirical evidence, and support the design of integrated interventions. This study underscores the need to strengthen universities' role in bridging agriculture, tourism, and policy to advance FLW reduction and support sustainable tourism development in rural destinations such as Sembalun, West Nusa Tenggara.

The proposed alternative layout is expected to achieve a safer, more hygienic, and more productive spatial arrangement by establishing a clear separation between the production zone, administrative zone, and supporting areas.

The main issues identified in this study include mistargeting of beneficiaries, weak inter-agency coordination, low community participation in the verification process, and a tendency among recipients to rely on cash assistance in a consumptive manner. This research analyzes the scenario planning of the Cash Transfer Program (BLT) in reducing poverty in Surabaya City, particularly in Krembangan District. The program is implemented based on Surabaya Mayor Regulation Number 130 of 2023, which serves as the legal foundation for the regional BLT scheme. Using the Scenario Planning TAIDA model (Tracking, Analysing, Imaging, Deciding, and Acting) by Mats Lindgren and Bandhold (2003) as the analytical framework, this study examines the extent to which planning, decision-making, and implementation processes are able to respond to the socio-economic dynamics of the community. Employing a descriptive qualitative method, data were collected through interviews, observations, and documentation. The findings indicate that BLT plays a significant role in supporting low-income households and reducing poverty rates; however, challenges persist, including limited community engagement, weak inter-agency coordination, and non-productive use of assistance. The scenario planning approach is considered effective in helping the government design more adaptive, participatory, and sustainable policy strategies. It is expected that the BLT program will not only serve as a short-term intervention but also become a strategic instrument in promoting independence and improving the welfare of poor communities in Surabaya.

The study aims to improve the passion fruit syrup production system at Harisma Home Industry, which has been hindered by an inefficient facility layout and complicated raw material flow. These issues lead to longer processing time, higher operator workload, and reduced production capacity. To solve this, the research uses the Activity Relationship Chart (ARC) and Total Closeness Rating (TCR) to evaluate and redesign the layout. TCR results show that the Raw Material Warehouse has the highest priority with a score of 119, requiring an Absolutely Important (A) relationship with the Production Room. The Parking Area and Waiting Room also fall into the Absolutely Important category, as they support smooth movements of materials and visitors. Meanwhile, the Toilet has a Very Important (E) relationship with the Waiting Room due to comfort and accessibility needs. Based on these proximity requirements, a new layout was designed by placing the Raw Material Warehouse next to the Production Room to create a faster and more efficient material flow. Other facilities were rearranged to minimize unnecessary movement. This new layout is expected to streamline processes, reduce congestion, and enhance overall capacity and operational performance.
