Abstract

Stunting is a chronic nutritional problem that has a serious impact on child development. This study aims to gain a deep understanding of the perceptions, knowledge, and practices of the community in Timbang Lawan Village regarding nutritional intake and stunting prevention. Through a qualitative approach using participatory observation and in-depth interviews, this study reveals the factors influencing feeding practices for toddlers, the challenges faced, and effective strategies to improve nutritional intake. The results show that low knowledge about nutrition, limited access to nutritious food, and socio-cultural factors are the main challenges in stunting prevention efforts.

Abstract

Proper monthly budget management is often a challenge for students, especially when they have to meet basic needs with limited resources. This study aims to improve monthly fund allocation for students through the use of the Big-M method in linear programming. A mathematical model is developed based on the priority of needs and limited budget, considering constraints in the form of inequalities (≥) that require surplus variables and additional variables. The Big-M method is applied in a simplex approach by giving a large penalty (M) to the additional variables to achieve an optimal solution. The findings of the study indicate that this method is effective in providing a balanced and efficient fund allocation between primary needs such as food and education, and also additional needs such as transportation and entertainment. Therefore, the Big-M method can be used as a logical and structured tool in student financial planning.

Abstract

The increasing demand for energy and the depletion of fossil fuel reserves have accelerated the development of renewable energy sources, with biomass emerging as one of the most promising candidates. Corncobs, an abundant agricultural residue with considerable energy content, represent a viable feedstock for gasification processes. This study evaluates the performance of a corncob-fueled updraft gasifier integrated with a photovoltaic (PV) solar power system as an auxiliary energy source for reactor operation. Experimental tests were conducted to assess flame characteristics, syngas composition, thermal efficiency, and overall energy potential. The influence of air flow rate (AFR) on temperature profiles across the drying, pyrolysis, oxidation, and reduction zones was systematically analyzed. The findings show that low AFR enhances heat accumulation but restricts oxygen supply, whereas excessively high AFR produces cooling effects that reduce thermal efficiency. Optimal operating conditions were achieved at intermediate AFR values (11.5–13.4 m/s), yielding stable heat distribution and high-quality syngas dominated by CO, H₂, and CH₄. Under these conditions, the system demonstrated promising thermal efficiency for small-scale applications. The 600 WP. PV system effectively supplied power to operate the blower, pump, and instrumentation, supporting operational autonomy and reducing reliance on external electricity sources. Overall, the integration of corncob gasification and solar energy offers a sustainable, environmentally friendly, and technically feasible hybrid energy solution, while promoting the utilization of agricultural waste and reducing dependence on fossil fuels in rural areas.
