Kepulauan Riau merupakan provinsi yang terdiri dari beberapa pulau diantaranya Pulau Batam, Pulau Bintan dan Pulau Karimun. Modal sosial merupakan serangkaian nilai dan norma informal yang dimiliki oleh kelompok masyarat dalam membagun kerjasamanya. Lingkup penelitian pada pembahasan ini adalah terfokus pada pengaruh modal sosial terhadap perkembangan pariwisata di Kepulauan Riau dalam hal ini Pulau Batam, Pulau Bintan, dan Pulau Karimun. Metode penelitian yang digunakan dalam penelitian ini adalah penelitian deskriptif kualitatif. Penelitian ini dikondisikan sebagai penelitian kualitatif melalui strategi studi kasus. Sistem pendekatan yang digunakan juga merupakan pendekatan deskriptif analitik. Melakukan pengamatan langsung, mengumpulkan data-data kemudian menghubungkannya dengan kajian teori yang digunakan. Lokus penelitian ini terdapat di Kepulauan Riau dengan melihat pengaruh modal sosial pada perkembangan pariwisata di ketiga pulau yaitu Pulau Batam, Pulau Bintan dan Pulau Karimun. Berdasarkan hasil survey yang saya lakukan di Kepulauan Riau, terutama pada ketiga pulau yaitu Pulau Batam, Pulau Bintan, dan Pulau Karimun, dari ketiga pulau tersebut ternyata pada Pulau Karimun perkembangan pariwisatanya tidak terlalu berkembang karena masyarakat yang tidak menerima adanya wisatawan terutama wisatawan mancanegara. Riau Islands is a province consisting of several islands including Batam Island, Bintan Island and Karimun Island. Social capital is a set of informal values ​​and norms that are owned by community groups in building cooperation. The scope of research in this discussion is focused on the influence of social capital on the development of tourism in the Riau Islands, in this case Batam Island, Bintan Island, and Karimun Island. The research method used in this research is descriptive qualitative research. This research is conditioned as qualitative research through a case study strategy. The system approach used is also a descriptive analytic approach. Make direct observations, collect data and then relate it to the study of the theories used. The locus of this research is in the Riau Islands by looking at the influence of social capital on the development of tourism in the three islands, namely Batam Island, Bintan Island and Karimun Island. Based on the results of a survey I conducted in the Riau Islands, especially on the three islands, namely Batam Island, Bintan Island, and Karimun Island, of the three islands, it turns out that on Karimun Island the development of tourism is not very developed because people do not accept tourists, especially foreign tourists.

The Impact

Recently, electric vehicles (EV) have gained much attention as a potential enabling technology to support CO2 emissions reduction targets. Relative to their internal combustion vehicle counterparts, EVs consume less energy per unit distance, and add the benefit of not emitting any carbon dioxide in operation and instead shift their emissions to the existing local fleet of power generation. However, the true success of EVs depends on their successful integration with the supporting infrastructure systems. Building upon the recently published methodology for the same purpose, this paper presents a “systems-of-systems” case study assessing the impacts of EVs on these three systems in the context of Abu Dhabi. For the physical transportation system, a microscopic discrete-time traffic operations simulator is used to predict the kinematic state of the EV fleet over the duration of one day. For the impact on the intelligent transportation system (ITS), the integration of EVs into Abu Dhabi is studied using a multi-domain matrix (MDM) of the Abu Dhabi Department of Transportation ITS. Finally, for the impact on the electric power system, the EV traffic flow patterns from the CMS are used to calculate the timing and magnitude of charging loads. The paper concludes with the need for an intelligent transportation-energy system (ITES) which would coordinate traffic and energy management functionality.

AbstractMountains provide a timely opportunity to examine the potential effects of climate change on biodiversity. However, nature conservation in mountain areas have mostly focused on the observed part of biodiversity, not revealing the suitable but absent species—dark diversity. Dark diversity allows calculating the community completeness, indicating whether sites should be restored (low completeness) or conserved (high completeness). Functional traits can be added, showing what groups should be focused on. Here we assessed changes in taxonomic and functional observed and dark diversity of epiphytic lichens along elevational transects in Northern Italy spruce forests. Eight transects (900–1900 m) were selected, resulting in 48 plots and 240 trees, in which lichens were sampled using four quadrats per tree (10 × 50 cm). Dark diversity was estimated based on species co-occurrence (Beals index). We considered functional traits related to growth form, photobiont type and reproductive strategy. Linear and Dirichlet regressions were used to examine changes in taxonomic metrics and functional traits along gradient. Our results showed that all taxonomic metrics increased with elevation and functional traits of lichens differed between observed and dark diversity. At low elevations, due to low completeness and harsh conditions, both restoration and conservation activities are needed, focusing on crustose species. Towards high elevations, conservation is more important to prevent species pool losses, focusing on macrolichens, lichens with Trentepohlia and sexual reproduction. Finally, dark diversity and functional traits provide a novel tool to enhance nature conservation, indicating particular threatened groups, creating windows of opportunities to protect species from both local and regional extinctions.

Change Mitigation

This paper proposes the use of decomposition analysis to assess the effect of local energy-related actions towards climate change mitigation, and thus improve policy evaluation and planning at the local level. The assessment of the impact of local actions has been a challenge, even from a strictly technical perspective. This happens because the total change observed is the result of multiple factors influencing local energy-related greenhouse gas (GHG) emissions, many of them not even influenced by local authorities. A methodology was developed, based on a recently developed decomposition model, that disaggregates the total observed changes in the local energy system into multiple causes/effects (including local socio-economic evolution, technology evolution, higher-level governance frame and local actions). The proposed methodology, including the quantification of the specific effect associated with local actions, is demonstrated with the case study of the municipality of Malmö (Sweden) in the timeframe between 1990 and 2015.

Photovoltaic Panels

Alternative energy resources have a significant function in the performance and decarbonization of power engendering schemes in the building application domain. Additionally, “green buildings” play a special role in reducing energy consumption and minimizing CO2 emissions in the building sector. This research article analyzes the performance of alternative primary energy sources (sun and hydrogen) integrated into a hybrid photovoltaic panel/fuel cell system, and their optimal synergy to provide green energy for a green building. The study addresses the future hydrogen-based economy, which involves the supply of hydrogen as the fuel needed to provide fuel cell energy through a power distribution infrastructure. The objective of this research is to use fuel cells in this field and to investigate their use as a green building energy supply through a hybrid electricity generation system, which also uses photovoltaic panels to convert solar energy. The fuel cell hydrogen is supplied through a distribution network in which hydrogen production is outsourced and independent of the power generation system. The case study creates virtual operating conditions for this type of hybrid energy system and simulates its operation over a one-year period. The goal is to demonstrate the role and utility of fuel cells in virtual conditions by analyzing energy and economic performance indicators, as well as carbon dioxide emissions. The case study analyzes the optimal synergy between photovoltaic panels and fuel cells for the power supply of a green building. In the simulation, an optimally configured hybrid system supplies 100% of the energy to the green building while generating carbon dioxide emissions equal to 11.72% of the average value calculated for a conventional energy system providing similar energy to a standard residential building. Photovoltaic panels account for 32% of the required annual electricity production, and the fuel cells generate 68% of the total annual energy output of the system.
