The increasing urgency of climate change mitigation necessitates the adoption of renewable energy sources to meet the growing demand for clean energy. Solar energy, in particular, presents a viable solution, contingent on the availability of sufficient land to optimize power generation. River land offers an alternative location for solar power plants, potentially conserving valuable land resources while providing a natural cooling medium for solar panels to enhance efficiency. This study evaluates the techno-economic feasibility of establishing a solar power plant system (PLTS) on river land in Surakarta City, Indonesia, using simulations conducted with the Hybrid Optimization Model for Electric Renewables (HOMER) software. The simulation considers both on-grid and off-grid systems, with a daily energy demand of 2,947.236 kWh projected over a 25-year period at the Tirtonadi Dam site. The On-Grid system demonstrated a total annual energy production of 885,358 kWh, significantly outperforming the off-grid system, which produced 34,400 kWh annually. The Net Present Cost (NPC) for the on-grid system was calculated to be USD 1,805,634.01, while the off-grid system's NPC was substantially lower at USD 1,970.18. The Levelized Cost of Energy (COE) for the on-grid system was found to be USD 0.09 per kWh, compared to USD 0.10 per kWh for the off-grid system, indicating favourable investment potential. The breakeven point (BEP) for the On-Grid system was achieved in the 0.54th year. The initial capital expenditure required to implement the on-grid PLTS at Tirtonadi Dam was estimated at approximately USD 47,782.10, while the off-grid system's initial cost was around USD 1,923.77. These findings suggest that the deployment of solar power plants on river land, particularly with an on-grid configuration, is a technically viable and economically advantageous approach to enhancing renewable energy capacity in Indonesia.

This study examines the influence of Arab-Islamic cultural memory on the spatial planning and design of streets within Palestinian refugee camps, with a particular focus on Nablus City. The research aims to ascertain how cultural elements, emblematic of collective memories among the camp residents, are incorporated into the urban redevelopment of these areas. A historical analysis of street design methodologies forms the basis of this inquiry, facilitating a comparative understanding of contemporary and traditional street layouts. Two case studies were selected to perform architectural surveys and field observations, illuminating commonalities between traditional and modern street designs. It was observed that the street configurations within the refugee camps not only mirror the collective memory of the Palestinian populace but also align harmoniously with the historic urban fabric of Nablus City. Contemporary street designs in these camps exhibit a plethora of architectural, visual, and cultural parallels with their traditional counterparts. These similarities include an organically developed street network, characterized by spontaneous growth and a privacy-oriented hierarchy of street types. Additionally, the serpentine nature of these streets, bending to adapt to the environment, further underscores their organic character. Privacy is a key design consideration, evident in features such as elevated windows, shaded balconies, and minimal openings in narrow passageways. The principal conclusion drawn from this study is the pivotal role historic urban models should play in guiding the development of refugee camps, particularly in the formation of street networks and patterns. It is posited that, with appropriate visual enhancements, the existing structure of many streets within these camps is well-suited to meet both social and aesthetic needs. In terms of expansion, an in-depth exploration of the socio-cultural implications of street design on community interaction and identity in these refugee camps could enrich the study. Investigating how residents perceive and interact with these spaces, and how these interactions shape community bonds and cultural identity, would provide a holistic understanding of the impact of urban design on refugee communities. Additionally, analyzing the role of contemporary urban planning policies in facilitating or hindering the preservation of cultural memory within these settings would be valuable. This could involve examining policy frameworks and their effectiveness in integrating traditional urban elements into modern planning practices.
