Abstract

Reservoirs play a strategic role in supporting water security, providing raw water, agricultural irrigation, and flood control in Central Java. However, over the past two decades, sedimentation has become one of the most serious problems threatening the sustainability of reservoir functions. The accumulation of sediments on the reservoir bed gradually decreases storage capacity and reduces operational effectiveness, particularly during the dry season when water demand increases. This study aims to comprehensively examine the impact of sedimentation on reservoir storage capacity through literature analysis and secondary case studies. The method employed is a systematic literature review with a comparative analysis approach of several major reservoirs in Central Java, namely Wadaslintang, Kedungombo, Sempor, and Mrica. Secondary data were obtained from previous research, official reports from the River Basin Agency (BBWS), and national scientific publications. The results show that high sedimentation rates have reduced the effective storage capacity of reservoirs by 15-40 percent of their initial capacity. The main contributing factors include soil erosion in catchment areas, land-use changes, and limited maintenance activities. Therefore, an integrated sediment management strategy is required, combining technical measures such as dredging and sabo dams with non-technical approaches based on land conservation and community participation. This study is expected to serve as a reference for sustainable reservoir management planning in Central Java.

Abstract

This study aims to analyse the manufacturing process, business model, and sustainability aspects of MuseumKu Gerabah in Kasongan, Bantul. A descriptive qualitative case study approach was employed through observation, semi-structured interviews, and document analysis. The findings reveal that the manufacturing process consists of four main stages: material preparation, forming (hand-forming, moulding, and wheel-throwing), drying, and traditional kiln firing using wood and straw. Wheel-throwing is identified as the primary training method due to its high replicability and transferable skills. The Business Model Canvas (BMC) analysis highlights strengths in cultural value, interactive experiential learning, and diversified revenue streams. However, challenges include the utilisation of traditional firing technology, limited digital integration, and ageing artisans. Thematic analysis indicates interconnected cultural, social, and environmental sustainability dimensions, although environmental performance requires improvement through greener technology adoption and digital transformation. Theoretically, this study integrates traditional manufacturing analysis, business model evaluation, and sustainable creative tourism frameworks.

Abstract

Located within the Pacific Ring of Fire, Indonesia experiences high seismic intensity, posing a risk of structural damage to bridges; thus, seismic load considerations are imperative in bridge engineering. Although bridge seismic analysis has been conducted, comparative studies of truss configurations under seismic loads remain limited. This study analyzes the influence of truss configurations, including Howe, Pratt, Warren, Quadrangular Warren, Whipple, Camel Back, Baltimore, K-Truss, and Petit Truss, under seismic loads through deflection and Demand Capacity Ratio (DCR) parameters. The analysis was performed using Midas Civil, a Finite Element Method software, while seismic loading was applied using the response spectrum method. The results show that the Camel Back Truss achieves the highest structural efficiency, yielding the lowest DCR, with a maximum of 0.064693 and 0.1503 for the mean. Regarding serviceability, Petit Truss exhibited the minimum deflection values of 0.02735 m, 0.02482 m, and 0.02493 m for Service I (TD), Service I (TT), and Extreme I, respectively. Overall, Camel Back Truss provides the best structural performance by maintaining the lowest stress ratio and the second-lowest deflection, recorded at 0.02725 m and 0.03897 m under Service I and 0.02818 m under Extreme I loads, respectively.
