There are two methods of road assessment, ie, visually and using tools. Visual assessment makes use of the PCI (Pavement Condition Index), while assessment with the Roadroid app can be used to obtain the value of IRI (International Roughness Index) with less cost. Functional assessment of roads in the field more use of visual methods. This method is influenced by the subjectivity of surveyors. Therefore, the assessment using the visual method should be correlated with the assessment method using tools, in order to reduce the subjectivity of road assessment. The research location used is Magetan District Road consisting of 5 road segments. The result shows that the r road assessment using the PCI method has a very good condition, and using IRI Roadroid has a Medium condition. There is a negative (r) correlation between PCI and IRI Roadroid, valued at -0.23. The negative correlation shows that both judgments reversed. Comparison of PCI assessment with IRI Roadroid has a low correlation value and with ttest, yields no comparison of correlation. This result is because the PCI and IRI equally assess the pavement, using different methods.
<p>Genangan pada saat musim penghujan menyebabkan kerugian di berbagai aspek. Agar penanganan dapat dilakukan secara efektif maka diperlukan analisis sistem drainase secara menyeluruh yang kemudian akan digunakan sebagai dasar penetuan penanganan genangan. Untuk menganalisis kapasitas sistem drainase eksisting dalam menampung debit hujan digunakan simulasi dengan <em>software</em> SWMM (<em>Storm Water Management Model)</em>. Pemilihan konsep penanganan didapatkan melalui simulasi ulang kapasitas saluran drainase agar dapat menampung debit rencana. Berdasarkan hasil simulasi menunjukkan kapasitas saluran drainase eksisting cukup baik namum terdapat 5 saluran yang melebihi daya tampung debit aliran yaitu C01, C09, C25, C26 dan C38. Kelima saluran tersebut mengalami kelebihan kapasitas selama 1 jam pada saat puncak debit yang terjadi pada jam ke 2. Konsep perbaikan yang dilakukan berupa penambahan kapasitas saluran drainase dengan cara penambahan lebar dan kedalaman saluran. Konsekuensi dari penambahan kapasitas pada saluran C25 dan C26 menyebabkan meluapnya saluran C27. Sehingga terdapat 6 saluran yang memerlukan penambahan kapasitas saluran</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
