    Banana stem is a known alternative to wood for the production of pulp and paper. During the production of paper, it is extremely important to save costs and time while at the same time enhancing the quality of produced paper. In the present study, the paper was developed from banana stem fiber by optimizing its density. Response surface methodology (RSM) using Box-Behnken design (BBD) was used to determine the optimum blending parameters of the developed papers. The influence of banana stem fiber amount (250-1000 g), water amount (1-2 litres), and blending time (5-10 min) on paper density was analyzed using the software Stat-Ease 360, Version 13. The optimum conditions of banana stem fiber amount, water amount, and blending time to achieve a density of 675.75 g/m3 were determined as 461.83 g, 1.31 liters, and 8.53 min, respectively. ANOVA results revealed that the quadratic model best fits the density response, with blending time and banana stem fiber amount as the most significant model terms. Linear effects were more predominant than quadratic and interaction effects. The developed density model was in close agreement with experimental findings with an R2 value of 0.9748. The developed paper had cellulosic contents, with volatiles as high as 82.11%wb and 2.11%wb ash composition. Future works on the thermal properties of paper are encouraged.

    When the guns stopped roaring: Acholi ngec ma gwoko lobo

    This article calls attention to the responsibility of universities to transform, through partnership, the community in which they are embedded. The authors suggest that, to find solutions to the various community challenges and achieve the UN Sustainable Development Goals (SDGs), universities need to engage in partnerships of knowledge co-creation with the community in ways that value local knowledge and experience. The article elaborates on the efforts of Gulu University Centre for Community Based Participatory Research and Lifelong Learning, located in Northern Uganda, to show the potential of co-constructing knowledge for community transformation. The centre is part of the Knowledge for Change (K4C) global consortium, which is a growing network for community-based research. The authors share three research stories of community-based research that reflect distinct challenges faced in Northern Uganda and effective community-engaged solutions. Through an exploration of the Acholi ontology and epistemology of interconnection, the authors demonstrate that local communities have the knowledge and experience to define and address local problem.
