Abstract

Sago bark waste (uyung) is abundant in Sungai Tohor Village, Kepulauan Meranti Regency, but has not been optimally utilized, causing environmental problems. Research conducted by the Environmental Engineering Study Program, Universitas Riau, has developed charcoal briquettes from sago bark, which are then implemented in the community to provide real impacts on improving quality of life and supporting the impactful campus program. This community service aims to assist local communities and businesses in improving the quality of sago bark charcoal briquettes to meet export standards and support village energy transition. The methods included counseling, Focus Group Discussions (FGD), technical training on briquette production, quality testing, and business management strengthening. The FGD held in Selat Panjang (September 18–21, 2025) involved 20 participants from strategic partners including the Meranti Regency Department of Industry and Trade, Department of Housing and Environment, Sago Center, Village-Owned Enterprises (BUMDes), and export practitioners from Ecotohor Solution. The results showed increased community understanding of export briquette standards with characteristics such as high calorific value, low moisture content, good density, and stable combustion. This technology implementation strengthens the potential of sago bark charcoal briquettes as a village flagship product for the global market while promoting energy transition and sustainable economy.

Abstract

PT Pindad, as a strategic state-owned enterprise, plays a crucial role in supporting Indonesia’s national defense industry. This study aims to analyze the company’s financial distress condition using the Altman Z-Score method and to forecast its 2024 financial position through time-series linear regression analysis conducted in Microsoft Excel. The analysis is based on financial statement data covering the period from 2019 to 2023.The findings reveal that PT Pindad consistently remained in the distress zone throughout the observation period, as indicated by its Z-Score results. Forecasting analysis further suggests a continued decline in financial performance in 2024 if no corrective measures are implemented. The Altman Z-Score model demonstrated an estimated predictive accuracy of 80% when compared with actual financial indicators, indicating that the model is relatively reliable in identifying potential financial distress conditions.However, this study is limited to a single company case study, which restricts the generalizability of the findings. Future research is recommended to conduct comparative analyses across multiple firms within the defense industry to provide broader insights. To improve long-term financial sustainability, recommended recovery strategies include debt restructuring, stricter capital expenditure control, operational cost efficiency, and optimization of marketing strategies and asset utilization.

Abstract

The demand for renewable energy continues to grow as fossil fuel reserves decline and global energy needs increase. One promising alternative is the vortex turbine, which can operate effectively in low-head regions. This study investigates the effect of blade geometry variations on the performance of a vortex turbine, with a particular focus on curved blades enhanced with spiral-shaped fins inspired by biomimetics. The research was conducted experimentally using three blade types: flat blades, curved blades, and curved blades with additional spiral-shaped fins resembling a snail shell structure. Tests were performed on a laboratory-scale vortex turbine prototype, measuring torque, power, and efficiency. The results showed that the flat blades produced the lowest efficiency (17.6%), the curved blades achieved a moderate efficiency (21.0%), whereas the curved blades with additional spiral-shaped fins reached the highest efficiency (33.01%). The significant improvement observed in the biomimetic blades is attributed to the spiral geometry, which effectively directs the flow, reduces separation, and enhances momentum transfer from the fluid to the blades. These findings demonstrate that the biomimetic approach contributes positively to improving the performance of small-scale vortex turbines, making it a promising solution for renewable energy generation in low-head regions
