“…Strong economic pressures have also been shown to shift traditional subsistence economic values towards beliefs consistent with the money economy [36]. So to ensure economic sustainability and social change, it is necessary to emphasize the state towards a more balanced development [37].…”

Aims: This study aims to analyze the social changes that have taken place in Kampung Sejahtera, Medan City, Indonesia. This social change was motivated by the community's desire to change the bad stigma attached to this area which is synonymous with drug trafficking, prostitution, gambling and other criminal acts into a village that is safe, comfortable, beautiful, prosperous and livable. Place and Duration of Study: This study was conducted in Kampung Sejahtera, Medan City, Indonesia. The research started from May 2022 to July 2023 Methodology: This study uses a qualitative approach. This qualitative approach was chosen to find out how social changes have occurred in the people living in the Prosperous Village of Medan City. The type of study used in this study is a case study. In simple terms, the case study in this study is defined as a process of in-depth and detailed investigation or examination of social change events that occurred in the Prosperous Village of Medan City. Results: Social change in Kampung Sejahtera, Medan City, Indonesia occurs through demographic processes, economic processes, ideas and social movements that have been going on for a long time. Conclusion: The social change that occurred in Kampung Sejahtera, Medan City was motivated by the people's desire to change the reputation of Kampung Kubur as a slum village and drug den inhabited by criminals to become a Prosperous Village that is safe, comfortable and conducive. The social changes that occurred in Kampung Sejahtera were generally initiated by figures from the community, government figures and the Police. The social changes that have occurred have changed the social structure that has occurred for the better. This can be seen in the reduction in drug trafficking and abuse, the creation of a better, beautiful and comfortable social environment as well as changes in the outside community's assessment of the bad reputation that was previously popular from Kampung Kubur to Kampung Sejahtera.

“…Biomassa é um termo utilizado para representar uma série de materiais orgânicos, como os resíduos agrícolas, que podem ser direta ou indiretamente empregados para a geração de combustí-veis, como etanol, metanol, biogás, carvão vegetal e óleos etc 6 . Pretende-se indicar qual ou quais destes materiais utilizados como adsorventes terão melhor aplicação no processo de adsorção para tratamento de efluentes contaminados com compostos orgânicos provenientes das etapas de extração e produção de petróleo.…”

Removal of hydrocarbons from aqueous effluents using biosorbents was investigated. The effluent was simulated by a dispersion of gasoline (simple hydrocarbons) in water. Corn-cob, wood powder, coconut mesocarp and sugar-cane bagasse were used as adsorbents and their performance verified by means of batch experiments performed in an agitated vessel. The influence of input variables such as hydrocarbon concentration, mass of biomass and agitation level on the adsorbents' capacity was studied by means of factorial design. The results indicated that, among the materials studied, coconut mesocarp and sugar-cane bagasse can be considered promising biomasses for treating aqueous effluents contaminated by hydrocarbons.Keywords: factorial design; petroleum; sugar-cane bagasse. INTRODUÇÃOA água é um dos recursos naturais mais intensamente utilizados. É fundamental para a existência e manutenção da vida e, para isso, deve estar presente no ambiente em quantidade e qualidade adequadas. O homem tem usado a água não só para suprir suas necessidades metabólicas, mas também para outros fins, como abastecimento industrial, irrigação, geração de energia, navegação, diluição de despejos e exploração e produção de petróleo 1 . Atualmente existe, em todo o mundo, uma grande preocupação com a água, não só por causa de sua escassez em algumas regiões, mas também por causa de processos constantes de poluição, principalmente em países ditos desenvolvidos.Os produtos orgânicos provenientes dos processos de extração e produção de petróleo são bastante prejudiciais ao homem e ao meio ambiente, pois causam sérios problemas de poluição à vida aquática em rios e lagos; por isso, as empresas de petróleo já procuram reduzir ao máximo este impacto ao meio ambiente.Mesmo em pequenas quantidades, os contaminantes orgânicos são difíceis de serem removidos, pois são estáveis à luz, ao calor e biologicamente não degradáveis; diminuem a área de contato entre a superfície da água e o ar atmosférico impedindo, assim, a transferência de oxigênio da atmosfera para a água, além de apresentarem problemas estéticos, produzindo a rejeição do efluente 2 . Por isso, vários processos de separação já são empregados pelas indústrias de produção de petróleo e refinarias. Dentre os processos de separação utilizados, a adsorção tem despertado bastante o interesse de pesquisadores e técnicos, por ser um processo eficaz para tratamento de efluentes orgânicos e metais pesados, utilizando materiais sintéticos, como as zeólitas 3 . Vários materiais adsorventes têm sido utilizados para a adsorção de contaminantes orgânicos e metais pesados, provenientes do petró-leo. O carvão ativo tem sido um dos mais empregados, principalmente por apresentar grande capacidade de adsorção. Possui, contudo, um elevado custo industrial, abrindo espaço para novas pesquisas 2,4,5 . A fim de reduzir o alto custo dos processos de separação por adsorção, principalmente devido ao elevado valor de alguns adsorventes, vários métodos alternativos têm sido estudados; entre estes, pode-se citar a bioa...

“…With foresight, people can minimize further biodiversity loss due to human activity. One important tool is biodiversity gap analysis, which has been developed by geographers and biologists to map distributions of vertebrate species and vegetation communities and identify gaps in their protection (McKendry andMachlis 1991, Scott et al 1993). This coarse filter approach can be used for conservation planning at the ecosystem level (Noss 1987).…”

Abstract. The semi-arid grasslands of the Colorado Plateau are productive, diverse, and extensive ecosystems. The majority of these ecosystems have been altered by human land use, primarily through the grazing of domestic livestock, yielding a plethora of environmental and social consequences that are tightly interconnected. From an agroecological perspective, untangling these issues requires both an understanding of the role of livestock grazing in bioregional food production and the effect of that grazing on ecological sustainability. To address the former, we discuss the importance of cattle ranching as a bioregional food source, including estimates of meat production and water use in Arizona. To address the latter, we present data from a long-term project addressing changes in native plant community composition, under a range of alternative livestock management strategies. Our study site near Flagstaff, AZ includes four different management treatments: (1) conventional low-intensity, long-duration grazing rotations; (2) high-intensity, short-duration rotations; (3) very high-impact, very short-duration grazing (to simulate herd impact); and, ( 4) livestock ex closure. Preliminary results suggest belowground properties are responding more quickly to grazing treatments than aboveground properties. Particular Email: MatthewR. Loeser, matthew.loeser@nau.edu 3 4 REFRAMINGTHEGRAZINGDEBATE response variables, such as cyanobacteria and diatoms, show a marked short-term response to very high-impact, short-duration grazing, but long-term implications are as yet unknown.
