Abstract

Merak Port Berth VII is exposed to wave action, seismic loading, and soft-soil conditions, while retrofit works must be planned under limited marine access and a constrained schedule. This study verifies a hybrid wave-damping system comprising a platform-mounted wavescreen and a causeway revetment to improve multi-hazard resilience. Wind data from 2010–2022 were used for wave hindcasting to derive return-period wave conditions, while seismic actions and structural checks were evaluated using Indonesian and international port design criteria. Platform performance was assessed at the ultimate and serviceability limit states, and revetment stability was analyzed using the Morgenstern–Price method. Under the 500-year design combination, the platform satisfied strength and serviceability requirements, with vertical bearing safety factors of 3.40 and 3.53 based on SNI and UFC combinations, respectively, and deformations within operational limits. The revetment achieved a factor of safety of 1.49 under the same demand but became inadequate under the 1,000-year scenario, indicating the need for strengthening when higher reliability is required. The estimated construction cost is IDR 132,205,000,000, with an estimated duration of approximately 216 working days. This verification framework is transferable to brownfield Indonesian ports exposed to combined coastal and seismic hazards.

Abstract

Limited access to adequate bathing, washing, and toilet facilities (MCK) remains a significant problem for residents of RT-03/RW-10, Polaman Sub-Village, Kalirejo Village, Lawang District, Malang Regency, so that some residents still use the river to meet their basic sanitation needs, potentially reducing their health and environmental quality. This Community Service Activity aims to provide simple WASH facilities that meet sanitation standards while promoting behavioral changes toward clean and healthy living through community participation. The implementation methods included an initial survey and interviews to identify the socio-cultural and environmental conditions, discussions to develop solutions with the RT administrators and residents, socialization with the PKK women's group, the construction of the MCK through the self-help efforts of students, donors, and the community during July-October 2025, and an evaluation in November 2025 through field observations, interviews, and documentation. The results of the activity include the construction of a simple, functional, and easy-to-operate toilet two units with a layout that meets comfort standards and better manages wastewater flow; increased community understanding of the importance of sanitation and environmental conservation; and a stronger spirit of cooperation in maintaining shared facilities. Overall, this program was deemed effective by residents and neighborhood association administrators in improving access to basic sanitation, reducing dependence on rivers as a means of sanitation, and supporting the creation of a cleaner, healthier, and more sustainable residential environment, while also providing a model for simple sanitation facilities that can be replicated in similar areas.
