Abstract

Nusa Penida, Bali was designated as a Marine Protected Area (MPA) by the Klungkung Local Government in 2010 with support from the Ministry of Marine Affairs and Fisheries, Republic of Indonesia. Mangrove forests located in Nusa Lembongan Island inside the Nusa Penida MPA jurisdiction have decreased in biomass quality and vegetation cover. It’s over the last decades due to influences from natural phenomena and human activities, which obstruct mangrove growth. Study the mangrove forest changes related to the marine protected areas implementation are important to explain the impact of the regulation and its influence on future conservation management in the region. Mangrove forest in Nusa Penida MPA can be monitored using remote sensing technology, specifically Normalized Difference Vegetation Index (NDVI) from Landsat satellite imagery combined with visual and statistical analysis. The NDVI helps in identifying the health of vegetation cover in the region across three different time frames 2003, 2010, and 2017. The results showed that the NDVI decreased slightly between 2003 and 2010. It’s also increased significantly by 2017, where a mostly positive change occurred landwards and adverse change happened in the middle of the mangrove forest towards the sea.

Abstract

The arrangement of coastal ecological space in the coastal city area aims to ensure the sustainability of the system, the availability of local natural resources, environmental health and the presence of the coastal ecosystems. The lack of discipline in the supervision and implementation of spatial regulations resulted in inconsistencies between urban spatial planning and land use facts. This study aims to see the inconsistency between spatial planning of the city with the real conditions in the field so it can be used as an evaluation material to optimize the planning of the urban space in the future. This study used satellite image interpretation, spatial analysis, and projection analysis using markov cellular automata, as well as consistency evaluation for spatial planning policy. The results show that there has been a significant increase of open spaces during 2001-2015 and physical development was relatively spreading irregularly and indicated the urban sprawl phenomenon. There has been an open area deficits for the green open space in 2015-2031, such as integrated maritime, ports, and warehousing zones. Several islands in Makassar City are predicted to have their built-up areas decreased, especially in Lanjukang Island, Langkai Island, Kodingareng Lompo Island, Bone Tambung Island, Kodingareng Keke Island and Samalona Island. Meanwhile, the increase of the built up area is predicted to occur in Lumu Island, Barrang Caddi Island, Barrang Lompo Island, Lae-lae Island, and Kayangan Island. The land cover is caused by the human activities. Many land conversions do not comply with the provision of percentage of green open space allocation in the integrated strategic areas, established in the spatial plan. Thus, have the potential of conflict in the spatial plan of marine and small islands in Makassar City.

Abstract

Development of the region by Minapolitan approach as a fisheries development concept cannot be applied partially but should be holistic developed by developing all the availability in cities to the rural areas. This study aims to understand the structure and pattern of regional economic growth and to find out the potency and competitiveness of the area as a priority for fisheries development center in Gorontalo Province. This study uses Klassen and Shift-Share (S-S) typology analysis. Area that has the better economic structure is Pohuwato Regency. This region has Gross Regional Domestic Bruto (GRDB) per capita above the provincial value, however economic development still below the provincial level (high income but low growth) or categorized as developed region but stressed category. Boalemo Regency, Pohuwato Regency and Bone Bolango Regency have almost equal fishery development value, which are 18.6%, 16.2% and 12.7% respectively. Gorontalo Regency grow only as large as 7.4 %. This is inseparable from the production of fishery sub-sector in Gorontalo Regency that only share 8% to the fisheries production.Development of the region by Minapolitan approach as a fisheries development concept cannot be applied partially but should be holistic developed by developing all the availability in cities to the rural areas.

Abstract

Calculation of carrying capacity of aquaculture area is important to optimize the coastal area utilization. The calculations of the spatial carrying capacity require the availability of accurate spatial data, and one of the best spatial data providers today is through the use of satellite imagery. This study aims to determine the ability of the pond land in support of the coastal community activities and regional development. This research covers two stages: 1) spatially identifies the pond area through the interpretation of ALOS AVNIR-2 satellite imagery with the masking technique; 2) Calculating the value of Carrying Capacity Ratio (CCR)  to know the ability of land to coastal community activities. The results show that the pond areas in Maros District identified as 9.621,60 hectares, and the CCR analysis shows a value of 2,79 or > 1. The value indicates the ability of pond land which is still relatively able to meet the needs of community activities. Bontoa sub-district is the region with the lowest CCR value (1,73), which means that the available of pond land is almost unable to fully support the communitys activities. Management strategies are needed in the form of increased productivity through the intensification patterns, and / or suppressing the population growth.

Abstract

Minawisata concept is the implementation and integration of efforts to optimize the utilization of marine and coastal resources with action to maintain the sustainability and value of sustainability. This study aimed to determine the suitability of the coastal land development in Pacitan District based on the potential of marine and coastal areas in accordance to the minawisata concept. Study area covered seven districts along the coastline of Pacitan District, East Java Province, namely Donorejo, Pringkuku, Pacitan, Kebonagung, Tulakan, Ngadirejo, and Sudimoro District. The methodology used in this study is a combination of Geographic Information Systems analysis, satellite imagery interpretation, and field data processing. This study is limited to the identification of the potential of marine and coastal area, the suitability of land use, and the suitability of coastal area development based on the minawisata concept. The results show that there are three dominant utilizations of marine and coastal areas in Pacitan District, including: Marine Aquaculture, Capture Fisheries, and Beach Tourism. Based on the analysis on suitability of the marine and coastal area, seven districts in Pacitan are suitable for fisheries and beach tourism, while only two districts were suitable for marine aquaculture with several conditions, namely Pacitan District and Ngadirejo District. The implementation of minawisata concept for coastal area suitability based on the analysis of seven identified districts is feasible for further development.

Abstract

Kestabilan dan keberlanjutan suatu sistem sosial ekologi di Kota Pesisir tergantung dari optimal dan efisiennya pemanfaatan energi sumber daya yang tersedia. Siklus autokatalitik dalam metabolisme kota pesisir memberikan gambaran nyata bagaimana energi sumber daya mengalir antara manusia dan sumberdaya alam dan bagaimana manusia mengatur dan memanfaatkan energi sumberdaya alam yang tersedia. Penelitian ini bertujuan untuk memodelkan siklus energi dan meterial dalam batas sistem kota pesisir yang mengakomodir semua sumberdaya alam yang menghasilkan energi yang dimiliki Kota Makassar dalam rentang waktu tertentu, sehingga mampu menunjukkan trend pemanfaatan dan keberlanjutan sistem dalam upaya menstabilkan diri terhadap dinamika penggunaan lahan dan pertumbuhan penduduk. Metode penelitian yang digunakan didasarkan pada konsep perhitungan aliran emergy dan indeks penilaian keberlanjutan metabolisme kota pesisir. Hasil penelitian menunjukkan bahwa total emergy yang mengalir di tahun 2001 sebesar 1,68E+21 Sej, meningkat menjadi 2,02E+21 Sej pada tahun 2015. Hasil analisis indeks keberlanjutan menunjukkan bahwa energi sumberdaya lokal sudah tidak mampu memenuhi kebutuhan energy masyarakat Kota Makassar, dan untuk memenuhi ketercukupan energi dalam sistem, input energi berupa impor sumberdaya mendominasi aliran energi dalam sistem. Tentunya diperlukan efisiensi dalam pemanfaatan energi sumberdaya, agar keberlanjutan metabolisme kota pesisir dapat terus berlangsung.

Abstract

Pengembangan wilayah dengan pendekatan minapolitan sebagai konsep pembangunan perikanan tidak bisa dilakukan secara parsial. Perikanan harus dibangun secara holisitik yaitu dengan membangun semua yang tersedia di perkotaan ke perdesaan. Penelitian ini bertujuan untuk mengetahui struktur dan pola pertumbuhan ekonomi wilayah dan mengetahui potensi dan daya saing lokasi sebagai prioritas pusat pertumbuhan perikanan di Provinsi Gorontalo. Studi ini menggunakan analisis tipologi Klassen dan Shift-Share (S-S). Wilayah yang memiliki struktur ekonomi relatif baik adalah Kabupaten Pohuwato. Daerah ini memiliki PDRB perkapita di atas nilai provinsi namun pertumbuhan ekonomi masih dibawah provinsi (high income but low growth), atau termasuk kategori daerah maju tapi tertekan. Kabupaten Gorontalo, Boalemo dan Bone Bolango termasuk dalam kategori relatif tertinggal (low growth and low income). Kabupaten Boalemo, Pohuwato dan Bone Bolango memiliki pertumbuhan subsektor perikanan yang hampir sama yaitu 18,6%, 16,2% dan 12,7%. Kabupaten Gorontalo hanya bertumbuh sebesar 7,4%. Hal ini tidak terlepas dari produksi subsektor perikanan Kabupaten Gorontalo yang hanya memiliki share 8% terhadap produksi perikanan. Untuk meningkatkan pertumbuhan ekonomi pada sektor perikanan, perlu memperhatikan hal-hal berikut: (a) menyediakan fasilitas publik, (b) pengembangan sektor perikanan secara terintegrasi, (c) pengembangan industri pengolahan hasil perikanan, (d) Pemda Kabupaten Boalemo dan Pohuwato, perlu melakukan tindakan pro aktif dan konstruktif untuk merangsang tumbuhnya minat penanaman modal disertai dengan peningkatan dan pembenahan kualitas SDM. Title: Regional Typhology Analysis for Developing of Minapolitan in the Gorontalo ProvinceRegional  development  by  using  Minapolitan  approach  is  as  a  fisheries  development  concept cannot be applied partially. Fisheries sector should be holistically developed by developing all of potency of rurals and urban areas. This study aims to: (1) understand the structure and pattern of regional economic growth, (2) find out the potency and competitiveness of the area as a priority for fisheries development center in Gorontalo Province. This study uses Klassen and Shift-Share (S-S) typology analysis. Finding of this study showed that has the better economic structure was Pohuwato Regency. This region has Gross Regional Domestic Bruto (GRDB) per capita above the provincial value. However, economic development is still below the provincial level (high income but low growth). It is categorized as developed region but they still under preasure of economy. Boalemo Regency, Pohuwato Regency and Bone Bolango Regency have almost equal fishery development value, which are 18.6%, 16.2% and 12.7% respectively. Gorontalo Regency is grow only 7.4 %. This is due to fisheries production in Gorontalo Regency is only share 8% of total fisheries production. In order to improve economic growth, is  fisheries  sector  need  to  pay  attention  to  several  important  points:  (a)  provide  public  facilities,  (b) development of an integrated fisheries sector, (c) development of processing industry, (d) Boalemo and Pohuwato regencies, need to tae action of pro-active and constructive to stimulate investor in improving quality of human resources.

Abstract

Kota Makassar merupakan sebuah sistem sosial ekologi yang kompleks dengan berbagai proses metabolisme energi di dalamnya. Penelitian ini bertujuan menggambarkan pola pemanfaatan energi secara sederhana dalam kerangka konsep metabolisme sosial di Kota Makassar. Pendekatan yang digunakan adalah Autocatalytic Feedback Loop. Hasil penelitian menunjukkan bahwa penggunaan lahan dan peningkatan konsumsi energi mengalami peningkatan seiring meningkatnya jumlah penduduk dan limbah. Di sisi lain, ketersediaan sumber daya lokal atau produksi perikanan, pertanian, dan peternakan mengalami ketidakstabilan produksi. Untuk menstabilkan sistem, sebagai suatu sistem yang selalu berusaha menstabilkan diri, Kota Makassar menstabilkan proses sistem dengan melakukan input sumber daya dari luar.Title:  The Useful Cycles of The Coastal Resources Energy By Human Activities Base on Autocatalytic Loop in Makasar CityMakassar City is a complex social ecological system with the various processes of energy metabolism in it. This study aims to describe simply the pattern of energy utilization within the framework of the concept of social metabolism in Makassar. The approach used is Autocatalytic Feedback Loop. The results showed that land use and energy consumption increased as population and waste increased.On the other hand, the availability of local resources or the production of fisheries, agriculture, and livestock have production instability. To stabilize the system, as a system that always try to stabilize itself, Makassar City stabilizes the system process by inputting external resources.
