Pengaruh Elemen Bentuk Perkotaan Terhadap Perilaku Pergerakan Non-Motor Di Up Tunjungan, Kota Surabaya
Get PDFBentuk Perkotaan dan mobilitas masyarakat merupakan dua hal yang tidak dapat dipisahkan dalam mengamati pola perkembangan tata ruang kota. Dalam konteks yang lebih mikro, bentuk perkotaan lebih spesifik dikaji berdasarkan elemen pembentuknya. Elemen bentuk perkotaan pada dasarnya mempengaruhi bagaimana pola mobilitas masyarakat khususnya mobilitas NMT. Hal ini ditunjukkan pada kondisi eksisting dibeberapa kota besar khususnya Kota Surabaya. Penyediaan fasilitas NMT telah gencar diimplementasikan, namun fungsinya belum optimal. Hal ini tentunya menimbulkan pertanyaan mengapa hal tersebut dapat terjadi sementara fasilitas NMT merupakan salah satu elemen bentuk perkotaan dari beberapa elemen lainnya. Dari hal tersebut, sekiranya perlu dikaji bagaimana elemen bentuk perkotaan mempengaruhi perilaku pergerakan NMT di Kota Surabaya khususnya pada UP Tunjungan.
Dengan menggunakan analisis multivariat kluster dan uji manova, penelitian ini menggunakan sampel KK sebagai objek penelitian. Dengan menggunakan random sampling pada setiap tipologi elemen bentuk perkotaan, penelitian ini menyajikan data-data terkait elemen bentuk perkotaan dan pola perilaku pergerakan NMT Masyarakat disetiap tipologi lokasinya.
Hasil dari penelitian ini menemukan adanya perbedaan jarak pergerakan NMT di UP Tunjungan Kota Surabaya karena adanya perbedaan tipologi elemen bentuk perkotaan terutama dari sisi jumlah persimpangan. Sementara salah satu elemen penting

Urban form and mobility of the people are two things that can not be separated in observing the pattern of urban spatial development. In the context of a more micro level, more specific urban form assessed by its constituent elements. Elements of urban form basically affect how people's mobility patterns, especially on mobility NMT. This is show in the existing condition in several major cities, especially in Surabaya. Provision of facilities for NMT has aggressively implemented, but its function hasn’t been optimal yet. The question of this problem is why it happened while NMT facility is one of the elements of urban form of some other elements. From this, is necessary to study how urban form elements influencing the behavior of the NMT movement in Surabaya, especially in UP Tunjungan.
By using multivariate analysis cluster and MANOVA test, this study used a sample of households as the research object. By using random sampling in each typology of urban form elements, this study presents the relevant data elements of urban form and behavior of community NMT movement patterns in each typology of location.
Results of this study found no difference in the UP Tunjungan NMT movement distance Surabaya due to the different typologies of urban form element especially in terms of the number of intersections. While one important element in the concept of the NMT NMT pathways did not affect the distance of movement in line with the magnitude of NMT. NMT movement distance on the

typology which has a higher number of intersections and low road density greater than the distance of movement in the location with the typology vice versa. As for some of the research findings indicate differences in perceptions about the near absence of distance in making the movement of NMT. 80.74% of samples given reasons do NMT movement because of their perceived close distance. The next indication is that the presence of a high number of intersections, affecting differences in these perceptions
How effective crowdsourced data during crisis emergency? A case of the 2018 Palu-Donggala earthquake
No full textIn disaster situations, updated geographic data is crucial for disaster relief efforts. OpenStreetMap (OSM) has demonstrated significant value in disaster response scenarios due to its capacity for rapid data collection and dissemination, since the 2010 Haiti earthquake. This study investigates the quality of OSM data during the 2018 Palu-Donggala earthquake, focusing on how contributor expertise affects data reliability and how effectively OSM data supports decision-making in emergencies. The research highlights the critical role of OSM in providing timely geospatial information, with 205 contributors mapping roads and buildings in Palu City and Donggala Regency within just three days of the earthquake. Our findings show that while road data exhibited substantial topological errors—7,085 errors primarily due to overshoots—building data had considerably fewer errors, with only 76 recorded. This disparity suggests that OSM data for buildings was of higher quality during the crisis. The preference of eight out of nine mapper types for building data over road data further underscores the value of OSM in emergencies, as experienced mappers tended to focus on features that were less error-prone. The study also evaluates contributor behavior, revealing that while a significant portion of contributors were inactive, a majority of experienced contributors remained engaged. This finding indicates the potential for inactive expert mappers to return and contribute in future crises. Additionally, the study assesses the rapid collection of data by OSM and its impact on decision-making. The National Disaster Management Agency of Indonesia (BNPB) and the ASEAN Coordinating Centre for Humanitarian Assistance (AHA Centre) effectively utilized the data to provide updates on fatalities, injuries, and displacement, facilitating a swift and equitable distribution of aid
Spatial Disparities in Jakarta’s Health and Education Infrastructures: An OpenStreetMap-Based Analysis
Get PDFJakarta, as Indonesia’s most populous megacity, had a population of 11.14 million in 2024. Covering an area of 661 square kilometers, it is also the country’s most densely populated city, with over 16,500 individuals per square kilometer. High population density brings challenges, particularly in access to essential public services like education and healthcare, which are crucial for sustainable urban development. This study examines spatial disparities in the distribution of health and educational infrastructures in Jakarta concerning population density. Through overlay analysis, two models were developed: the Educational Facilities Gaps Map and the Health Facilities Gaps Map, categorizing areas as well-served, moderately served, or underserved. The findings highlight significant disparities across Jakarta’s administrative regions. Central Jakarta has the highest accessibility, with 57.43% of its area well-served for education and 65.06% for healthcare. Conversely, North Jakarta and Kepulauan Seribu experience the most severe service gaps, with 51.92% and 100% of their areas underserved in education, and 50.20% and 85.92% in healthcare, respectively. East, South, and West Jakarta exhibit moderate service coverage, though underserved zones remain. These results emphasize the importance of strategic urban planning to improve equitable access to public services. By incorporating geospatial analysis into policymaking, decision-makers can optimize facility distribution and infrastructure development, reducing service disparities, especially in underserved areas

Disturbance tolerance of arbuscular mycorrhizal fungi : characterization of life-history strategies along a disturbance gradient in a coastal dune ecosystem
No full textPurposeArbuscular mycorrhizal fungi that regenerate rapidly after disturbance play a significant role in vegetation resilience. We employed the fungi inhabiting a coastal dune ecosystem to characterize their strategies for survival and regeneration after disturbance.MethodsRoot-soil samples were collected from the seaward and landward slopes that differ in disturbance severity. The native grass Miscanthus sinensis (donor plants) were grown in the soil samples for two months, and from a half of the plants, disturbance-tolerant fungi that regenerate from spores and extraradical hyphae (soil propagule-mediated regenerators, SP) and those that regenerate from the colonized roots (root-direct regenerators, RD) were trapped separately with new seedlings (assessment plants). The other half of the donor plants were further grown without destruction for four months together with assessment plants, during which the fungi trapped by the plants were categorized as disturbance-sensitive slow regenerators (SL). DNA was extracted from the assessment plants for identification based on LSU rDNA sequences.ResultsAll the fungi that occurred widely in the seaward samples belonged to the Glomeraceae and Paraglomeraceae and preferred the RD strategy to the SP strategy. In the landward samples diverse taxa that employed diverse strategies occurred, and among them, Gigasporaceae fungi showed a distinct preference for the SP strategy.ConclusionThese observations suggest that not only soil-borne propagules but also colonized roots play a key role in the rapid regeneration of the fungi after disturbance, providing a new insight into the life-history strategies of AM fungi in frequently disturbed environments
Cross-Functional Collaboration in Sustainability Contexts: Exploratory Studies in Remanufacturing Companies
No full textAbstractA plethora of remanufacturing research investigates production planning and control; however, there remains a lack of understanding regarding managerial and organisational issues in remanufacturing, in particular how the different functions of remanufacturing companies collaborate. In a conventional manufacturing context, cross-functional collaborations have not been much investigated, while in a remanufacturing context the lack of understanding of this topic is even worse. Motivated by this research gap, this study attempts to investigate cross-functional collaborations in remanufacturing companies. To do this, the author presents a review of current literature to identify gaps, and thereafter proposes a set of research questions. The research design and methods are discussed, as well as a justification of why they were chosen. The main contributions of this study are twofold; first, it identifies areas within remanufacturing companies that require cross-functional collaboration. These collaborations are unique and cannot be found in conventional manufacturing companies. Second, the study describes how these collaborations work. Some differences between these collaborations and those within conventional manufacturing are also discussed. In the last section, the author concludes and summarises the contribution to knowledge, the implication for practical fields and potential limitations of this study that can be addressed in future investigations
