| Summary: | <p class="IsiAbstract"><span lang="IN">The research aimed to seek factors causing ineffectiveness of Polder Tawang; the loss due to rob, the need, and the priority scale program in optimizing the polder. Its locus was Semarang city, especially areas located nearby the polder affected by rob such as Johar, Jurnatan, and Tawan station. Data was gathered by conducting interview, observation, and documentation. To analyze the data, description and </span>Analysis Hierarchy Process (AHP)<span lang="IN"> were employed. The result revealed that there were barriers in the management of Tawang Polder. The internal barriers were the broken water pump, leaking pump, unwaterproof polder, and polder which has less capacity over the water, and area which has less capacity to obsorb the water. The external factors were conflict areas, unwell managed infrastructure and rubbish, and inappropiate drainage system. These conditions led to some losses. They were the two working hours loss, and 11-15% downfall of turnover. Hence, there is a need to manage Tawang Polder either internally or externally. The internal ones are draining pump, waterproof pond, and absorption area determination. The external ones are independent polder management enabling the focus of the work, the involvement of consultant, monitoring , and better participation to optimize the polder. The priority programs resulted from AHP analysis were found to be government policy, infrastructure aspect, social and technical management aspect. </span></p><p class="IsiAbstract">Penelitian ini bertujuan mengetahui faktor-faktor penyebab belum efektifnya Polder Tawang <span lang="IN">meliputi</span> bentuk dan nilai kerugian yang diderita akibat rob,<span lang="IN">k</span>ebutuhan yang diperlukan, skala prioritas optimalisasi.
