Sustainability assessments of marine protected areas (MPAs) are essential for improving the effectiveness of management efforts. Since sustainability is closely related to the concept of intergenerational well-being, measuring and tracking it through time is crucial. Therefore, this study will use the system dynamics approach applied at Pieh marine park as the study site. A system dynamics model was built comprising four sub-models: fish population dynamics, coral reef coverage, tourism, and pollution. The goodness-of-fit test of the model indicated low and unsystematic model error. The sustainability assessment was conducted using the three principles of sustainability proposed by Herman Daly, which define sustainability for resource management based on the change in the amount of renewable resources, non-renewable resources, and pollution. The sustainability assessment determined that Pieh marine park cannot sustain economic activities in its area, indicated by decreasing renewable resource indicators in the form of fish population dynamics, coral reef coverage, and increasing pollution levels. Several management interventions can be applied to improve sustainability, including lowering the total allowable catch, coral transplantation, and improved waste management.

Smart village merupakan sebuah konsep yang baru berkembang di dunia dan menjadi fenomena baru digunakan untuk menyelesaikan berbagai permasalahan di desa. Desa Ketapang merupakan salah satu desa di kabupaten Banyuwangi yang telah berhasil mengadopsi konsep ini untuk dikembangkan di wilayah mereka. Dalam penerapannya berhasil digunakan untuk mengatasi berbagai permasalahan yang terjadi di desa. Untuk itu perlu dilakukan penelitian untuk menjelasakan tahapan pengembangan dan faktor-faktor apa saja yang berpengaruh dalam pengembangan konsep ini sehingga berhasil. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi kasus eksploratif berbekal sedikit teori dan mengeksplorasi kasus dilapangan. Hasil dari penelitian ini, tahapan perkembangan smart village terdiri dari empat tahap yaitu tahapan persiapan (2011-2015), tahapan pelaksanaan (Akhir 2015-2016), tahap pengembangan (2017-2018) dan tahap monitoring dan evaluasi. Program kegiatan yang dilakukan dalam tahap persiapan terdiri dari pembangunan infrastruktur TIK dan pengembangan aplikasi layanan, penyiapan sumber daya aparatur pemerintah dan pengembangan komunitas masyarakat.Faktor-faktor yang berpengaruh dalam tahapan pengembangan smart kampung antara lain faktor kepemimpinan, teknologi, dukungan warga dan alokasi anggaran. Abstract: Smart village is a concept that has just developed in the world and has become a new phenomenon used to solve various problems in the village. Ketapang Village is one of the villages in Banyuwangi district that has successfully adopted this concept to be developed in their area. In its implementation, it was successfully used to overcome various problems that occurred in the village. For this reason, research is needed to explain the stages of development and what factors are influential in developing this concept so that it works. This study uses a qualitative approach with explorative case study methods armed with little theory and explores cases in the field. The results of this study, the stages of development of smart village consist of four stages, namely the preparation stage (2011-2015), the implementation stage (End of 2015-2016), the development stage (2017-2018) and the monitoring and evaluation stages. Factors that influence the stages of smart village development include leadership, technology, citizen support, and budget allocations.The phases of the village smart development of Ketapang consist of the preparation stage (2011- 2015), the stage of implementation (2015-2016), the development stage (2017-2018), and the Monitoring and evaluation stage (in each year). The Program activities conducted in the preparatory phase consist of ICT infrastructure development and Service application development, government apparatus resource preparation and community development.

Yogyakarta is one of city in Indonesia which experience urban agglomeration called by Yogyakarta Urbanized Area (YUA). In this paper, identified the characters of each part of YUA by examining its urban form unit. This paper assesses the characteristics of urban forms distributed within YUA. Quantitative measurements were proposed for classifying the urban form typologies. Density, diversity, and accessibility were used to represent the urban form characteristic., the typologies are classified into three groups which are low compact, middle compact, and high compact. The result shows that the majority areas in YUA are grouped into middle compact typology where most of them are located in the city of Yogyakarta administrative area. Meanwhile, the areas, categorized as low compact typology, are in the hinterland area of Yogyakarta. High compact typology are concentrated in the centre of YUA where it has the highest activity concentration for the whole urban structure context. This study discovers that characterizing the urban growth patterns using quantitative method can distinguish urban form. At the end, this paper provides an important note about the distribution of urban form typology in the agglomeration area and, in the future, can be used to design urban policies, especially in the utilization of urban space.

Social structure is one of the important elements in development. Elements in the social structure will form relationships and form joint actions on the program.
