    ABSTRACT Rawapening Reservoir is part of the watershed Tuntang, which began to show the failure of its function as a support system of water resources in support of life. It is seen causing various water-use conflicts, particularly between upstream and downstream watershed Tuntang, so the incidence of floods and droughts are becoming more frequent and declining agricultural production, fish and hydroelectric increasingly felt. Watershed management requires coordination and in addition quite a long time, the necessary financing is also very large. One alternative financing watershed management is the Environmental Services payment of the service users, one of which is Jelok and Timo hydroelectric. The second hydropower received environmental services such as water availibility to rotate turbine. When environmental conditions are degraded, services rendered either degraded, uneven distribution of water availability and floods and droughts are becoming more frequent. Above conditions and make Jelok and Timo Hydroelectric losses (production target is not reached), the loss of electivity production due to the loss of environmental services tahat can be enjoyed. To cover the shortage of electricity production, PLN would be cost to turn the other energy sources, the cost is equivalent to the loss environmental services. Hence, in the environmental services can still be enjoyed at its optimum, the costs incurred by PLN, to supply production targets can be referred to as the cost of environmental services, this concept is known as the concept of replacement cost. Results for power production Jelok and Timo hydroelectric analyses, known to occur at the optimum production on Mart 32.99. While the value of environmental services that have been enjoyed in the 0ne years12.321 M. Keywords: environmental services, Jelok hydropower, Timo hydropower, Rawapening Resevoir, Watershed Tuntan

    ABSTRACT The increasing incidence of floods and droughts from year to year, indicating the destruction of water catchment areas. To the rescue of the catchment area should be done immediately. Preparation of spatial plans must accommodate the rescue catchment areas purpose, with no opening forests in the region. Opening of the forest to the wake region will be lead to increase floods and droughts in the downstream region. From year to year the condition persists, so the level of water availability has declined and losses due to floods has increased. Water crisis increasingly felt, not only in Indonesia, even this is global crisis, the longerof the water crisis is getting worse and leads to a disaster that the solution must be done immediately. Evaluation characteristics of the catchment area as a manufacturers producing surface water and groundwater needs to be done, to assess changes in the characteristics of the catchment area, towards the conservation of water resources can be focused and on target. Because it is associatednwith water results, then evaluation characteristics of the catchment area is done with the approach flow parameters in rainfall models. One of the popular models used rain flow, especially in the Java is FJ.Mock models, this model was developed from research in several watersheds in Java. From the research to changes in catchment characteristics with Mock model approach to Rawapening Reservoir catchment, from year to year decreased infiltration parameter values, whereas the direct flow increased. Refers to changes in the characteristics of the DTA, conservation activities to be done is to increase the infiltration capacity and reduce flow area directly. While the analysis of land use change, forest area declined from year to year and the areas of increased impermeable. Keywords: catchment areas, direct flow, Mock, and Infiltratio

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    The increasing global demand for sustainable food production necessitates the adoption of low-carbon and efficient agricultural practices. This study explores the application of smart farming technologies to chili cultivation, particularly in Indonesia, a region where chili farming significantly contributes to the agricultural economy but faces challenges of resource inefficiency and greenhouse gas (GHG) emissions. Smart farming integrates Internet of Things (IoT) devices, automated irrigation, and precision agriculture to optimize water, fertilizer, and energy use, reducing the carbon footprint of chili production. The research, conducted through a systematic literature review, identifies strategies such as IoT-enabled soil moisture sensors, precision irrigation systems, and targeted fertilization techniques. These approaches collectively enhance resource efficiency and mitigate environmental impacts. When integrated with renewable energy solutions, such as solar-powered irrigation, these technologies further reduce reliance on fossil fuels, promoting both economic viability and environmental sustainability. Key findings reveal that precision agriculture not only mitigates GHG emissions but also improves crop resilience and profitability by reducing input costs and enhancing yields. The integration of renewable energy further aligns chili farming with Indonesia’s climate action goals, promoting a model for sustainable agricultural development. This study underscores the importance of adopting low-carbon smart farming practices to achieve greater agricultural resilience, food security, and environmental stewardship in the face of climate change

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Dispelling the Myths Behind First-author Citation Counts

    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods
