Analisis Dampak Keterbatasan Persediaan Bahan Pangan di Pasar MMTC : Perspektif Konsumen
No full textThis research aims to analyze the impact of limited food supplies in the MMTC market. Pasar Raya Medan Mega Trade Center (MMTC) is a market located on Jalan Memori Baru, Percut Sei Tuan District, Deli Serdang. This market looks increasingly busy, especially at night from midnight. 11.00 until morning. The hustle and bustle of loading and unloading of goods from various regions with their respective buyers. Pasar Raya Medan Mega Trade Center (MMTC) is one of the largest traditional markets in Medan, North Sumatra, Indonesia. This market is famous for its various kinds of fresh products, including foodstuffs. However, in recent years, there has been increasing concern about limited food supplies in this market. This has led to negative impacts on consumers, such as higher prices, fewer choices and lower quality
INTEGRATING SPATIAL MAPPING AND SOCIO-CULTURAL DYNAMICS FOR SUSTAINABLE ECOTOURISM MANAGEMENT AT GOA ERGENDANG: A GEO-ANTHROPOLOGICAL STUDY IN DELI SERDANG REGENCY
No full textGoa Ergendang, a unique geo-cultural site in Deli Serdang, Indonesia, possesses significant ecotourism potential, including natural hot springs, stalactites, and rich local folklore (the Umang mythos). However, its development is severely hindered by informal community self-management, poor infrastructure, and a critical lack of spatial information for visitors. This research aims to (1) identify the fundamental challenges in its sustainable management and (2) formulate an integrated management model based on a geo-anthropological approach. This study employed a mixed-method design, integrating quantitative spatial analysis (GIS) with qualitative socio-cultural analysis. Methods included GIS mapping for accessibility, topography, and potential zoning, combined with in-depth interviews with local managers, stakeholders, and visitors. The findings reveal four primary challenges: (1) weak institutional capacity due to informal management, leading to resource limitations and poor heritage protection (e.g., the destruction of the "sacred drum stone"); (2) severe infrastructural barriers, particularly damaged access roads; (3) a critical spatial information gap, evidenced by 16 hidden pools remaining unknown to visitors due to a lack of maps; and (4) high physical vulnerability from steep topography and corrosive acidic water. This research proposes a sustainable management model based on Community-Based Ecotourism (CBT) supported by GIS planning. In this model, GIS functions as the objective physical planning tool for conservation zoning and visitor navigation, while a formalized community institution (e.g., BUMDes/Village-Owned Enterprise) acts as the socio-cultural manager, responsible for revitalizing local culture (Ergendang and Umang myths) as a core attraction. This integrated geo-anthropological model provides a clear pathway to optimize the area's unique potential sustainably
Venetian cardinals at the Papal Court during the pontificates of Sixtus IV and Innocent VIII : 1471-1492
No full textThe histories of particular cities and states within that myriad-faceted
slice of civilisation, the Renaissance in Italy, have received
more scholarly attention than have the diplomatic, ecclesiastical and
cultural connections between them. This study is part of a balance-redressing
process. Senior clerics traversed frontiers, owing
allegiance to their native state, their benefices and, above all, to
the Papacy. The purpose of this exploration of the curial careers of
four later quattrocento Venetian cardinals is essentially twofold : to
account for relations between Venice and the Papacy with reference to
individuals who were at once Venetian patricians and princes of the
Church; and to examine the cardinals' responses to this situation in
terms of political, ecclesiastical and cultural patronage. Where did
their loyalty lie? To Venice, with its perennial suspicion of the
Church and peculiar notion of the characteristics of a Venetian
cardinal? Or to the Pope, expressing overt hostility towards the
Republic in the War of Ferrara and placing it under an interdict?
Chapter one sets Merco Barbo, Pietro Foscari, Giovanni Michiel and
Giovanni Battista Zeno in a Venetian context. Chapters two and three
chart relations between the two powers, from the exposure of Cardinal
Zeno's involvement in a scheme to transmit Venetian state secrets to
Rome in exchange for ecclesiastical preferment, through to Ermolao
Barbaro's controversial appointment to the patriarchate of Aquileia,
via the short-lived Papal-Venetian league negotiated by Cardinal
Foscari in 1480. The fourth chapter considers their proximity to the
Supreme Pontiff and how their material fortunes varied under popes
Sixtus and Innocent, after which an assessment of the nature, extent
and effectiveness of their patronage is divided between chapters five
and six, focussing pa.rticularly on Venetian connections. Despite
diverging careers, it is concluded that all were bound by variations
of the Venetian inheritance

No full textAmazonia's floodplain system is the largest and most biodiverse on Earth. Although forests are crucial to the ecological integrity of floodplains, our understanding of their species composition and how this may differ from surrounding forest types is still far too limited, particularly as changing inundation regimes begin to reshape floodplain tree communities and the critical ecosystem functions they underpin. Here we address this gap by taking a spatially explicit look at Amazonia-wide patterns of tree-species turnover and ecological specialization of the region's floodplain forests. We show that the majority of Amazonian tree species can inhabit floodplains, and about a sixth of Amazonian tree diversity is ecologically specialized on floodplains. The degree of specialization in floodplain communities is driven by regional flood patterns, with the most compositionally differentiated floodplain forests located centrally within the fluvial network and contingent on the most extraordinary flood magnitudes regionally. Our results provide a spatially explicit view of ecological specialization of floodplain forest communities and expose the need for whole-basin hydrological integrity to protect the Amazon's tree diversity and its function.
