No full text
Komodo (Varanus komodoensis) dengan kehidupan liarnya hanya ada satu-satunya di dunia, yaitu di Taman Nasional Komodo (TNK), Nusa Tenggara Timur, Indonesia. Upaya konservasi dilakukan dengan mempertimbangkan daya dukung dan daya tampung agar tetap sejalan dengan prinsip pengelolaan wisata berkelanjutan. Penelitian ini bertujuan untuk menganalisis daya dukung daya tampung (DDDT) kunjungan di Pulau Komodo dan Pulau Padar. Metode yang digunakan dalam penelitian ini adalah analisis sistem dinamik. Jumlah satwa Komodo pada tahun 2045 diperkirakan meningkat menjadi 4.000-4.500 ekor di TNK atau sekitar 2.500 ekor di Pulau Komodo dan Pulau Padar, hal ini dikarenakan jumlah prey yang juga masih cukup tersedia pada luasan habitatnya. Tetapi apabila tanpa penerapan net zero emission akan ada tekanan terhadap populasinya yang dapat turun mencapai 800-900 ekor di Pulau Komodo dan Pulau Padar. Peningkatan suhu terjadi hingga tahun 2045 mencapai 0,8°C. Pada sisi jumlah kunjungan di Pulau Komodo yang ideal berdasarkan hitungan DDDT sebanyak 219.000 kunjungan/tahun, pada Pulau Padar jumlah kunjungan yang ideal sebanyak 39.420 kunjungan/tahun dan dapat ditingkatkan hingga 2-2,5 kali.Komodo (Varanus komodoensis) with its wildlife is the only one in the world that lives in the Komodo National Park (KNP), East Nusa Tenggara, Indonesia. The conservation efforts are carried out by considering the carrying capacity to remain in line with the principles of sustainable tourism management. This study aims to analyze the carrying capacity of the visits carrying capacity on Komodo Island and Padar Island. The method used in this research is system dynamics analysis. The number of Komodo dragons in 2045 is estimated to increase to 4000-4500 Komodo dragons in KNP or around 2500 Komodo dragons in Komodo Island and Padar Island since the number of preys is still quite available in their habitat. However, without the implementation of low carbon development, there will be pressure on its population, which can drop to 800-900 Komodo dragons both on Komodo Island and Padar Island. Meanwhile, the temperature increase occurs until the year 2045 which reaches 0.8°C. In terms of the ideal number of visits on Komodo Island based on the carrying capacity calculation of 219,000 visits/year, on Padar Island the ideal number of visits is 39,420 visits/year and it can be still increased up to 2-2.5 time
The analyze of green space need in Surabaya City using Gerarkis Method for 2010–2020
Get PDFKota Surabaya merupakan kota terbesar kedua di Indonesia dengan penduduk terbanyak sehingga mengalami perkembangan dalam tata kota. Efek dari adanya perkembangan wilayah perkotaan adalah meningkatnya perkembangan sosial ekonomi dan demografi peri-urban namun seringkali mengambil alih lahan atau ruang terbuka hijau sehingga tidak terhindarkan dari kemungkinan pencemaran udara karena tidak seimbangnya produsen oksigen dengan pengguna oksigen yang ada. Sehingga diperlukan perhitungan prediksi kebutuhan ruang terbuka hijau menggunakan Metode Gerarkis yang merupakan metode untuk memprediksi ruang terbuka hijau berdasarkan kebutuhan oksigen dengan menggunakan jumlah penduduk, kendaraan bermotor, hewan ternak, pabrik industri, dan hotel. Melalui Metode Gerarkis, prediksi kebutuhan ruang terbuka hijau yang dibutuhkan Kota Surabaya pada tahun 2010 – 2020 sebanyak 22.088,89 Hektar sampai dengan 31.950,84 dengan mayoritas kenaikan luasan kecuali tahun 2015 dan 2020 dikarenakan adanya penurunan jumlah pengguna. Hal ini membuktikan bahwa kebutuhan oksigen yang diproduksi dari tanaman semakin meningkat sehingga membutuhkan lebih banyak lagi ruang terbuka hijau untuk menjadikan Kota Surabaya menjadi kota yang nyaman untuk ditinggali.Surabaya City is the second-largest city based on the population in Indonesia that is affected by the development of urban planning in the city. The development of the urban areas affected the increase of socio-economic development and peri-urban demographics but often took over land or green open spaces. It is an unavoidable possibility of air pollution due to the imbalance between oxygen producers and existing oxygen users. It is necessary to calculate the prediction of green open space requirements using the Gerarkis Method, which predicts green open spaces based on oxygen demand by using the number of residents, motor vehicles, livestock, industrial factories, and hotels. With the Gerarkis Method, the prediction of the need for green open space in Surabaya City for 2010–2020 is 22,088.89 hectares to 31,950.84 with the increased majority value in the area, except in 2015 and 2020, due to decreased users. This method proves that the need for oxygen produced from plants is increasing, making Surabaya City needs more green open space to make Surabaya City livable
Changes in land use impacted air temperature in Bekasi Regency
Get PDFIndonesia is experiencing dynamic land change. One area in Indonesia that has experienced high land use change is Central Cikarang District. Landsat 9 image sensing and land cover data from the Ministry ofEnvironment and Forestry show the increased temperature in the Central Cikarang District area since 2004. Based on the NDVI analysis, the residential area has increased, and the area of green vegetation hasdecreased. Analysis of temperature changes using satellite imagery also shows a wider distribution of hot temperatures in the 2004–2022 range. From the two data analyses that were carried out, a regression test was carried out to determine the correlation between air temperature and vegetation density. The results of the regression test obtained an R2 value of 7.2%. It is also known that the value of the regression coefficient is negative, which means that the correlation of the two data is inversely proportional. So this research analyzes changes in land cover to changes in temperature. 
Ecological Adaptation as a Form of SDG\u27s Achievement Attempts for The Community in Conflict Areas through Poverty Alleviation
No full textThe effect of the conflict in Poso on the community agricultural activity is significant. The objective of this research is to observe the community adaptive behaviour in responding to the environmental changes. The research was carried out in three villages in Poso. The data was collected through interview, and the analysis carried out through cybernatic analysis. The research result waspresented that most of the community was pro-actively adapted, to adjusted of the plantation agriculture pattern to the basic crop agriculture. The factors that influenced the community adaption strategy were the activities in the program, education, and social status. The adaption behaviour had also a high corelation with the level of independency, whereas the higher the level of indepedency people, the more adaptive the behaviour is. There are relation between the village durability index with the village typology, whereas a village with a typology of mountainous areas and far from urban areas, its environmental tenacity index is very good. While villages with a typology of community diversity are high, have a good social tenacity index. With regard to SDG\u27s achievements, the empowerment program in Poso has achieved SDG\u271, 5, 10 and SDG\u27s 16

SPECIES COMPOSITION, STRUCTURE, AND MANAGEMENT IN GAYO COFFEE-BASED AGROFORESTRY SYSTEM: The Case of Mude Nosar Village, Central Aceh Regency
Get PDFGayo coffee has many benefits in terms of the environment, economy, and socio-cultural aspects, especially for the Gayo tribe. Recently, Gayo coffee has been the main commodity for the plant cultivation of the Gayo tribe, including the Mude Nosar as local farmers. One of the ways to cultivate Gayo coffee is through an agroforestry system. However, limited reports on the tree species composition and its management in Gayo coffee-based agroforestry needs to be explored. This study aims i) to identify the tree species composition and structure, as well as 2) to analyze the management of Gayo coffee-based agroforestry system in Mude Nosar Village. The study method used plot establishment for vegetation analysis, and interviewed the Gayo coffee farmers. The results showed that the number of tree species at all growth stages was 26 species. The highest Important Value Index (IVI) at the understory and sapling level in order was rumput kerbau (Paspalum conjugatum) and Gayo coffee (Coffea arabica), while at the seedling, pole, and tree levels were dominated by lamtoro (Leucaena leucocephala). The local farmers often use lamtoro as a shade tree for Gayo coffee in agroforestry system. The species diversity index (H\u27) showed low values at all growth levels, except for understory plants with moderate values. The horizontal structure of the tree stand showed an inverted J curve, meaning that the regeneration rate is normal. The vertical structure of the tree stand belongs to strata C and D. The local farmers have applied good Gayo coffee management practices through an agroforestry system including land and seed preparation, planting, maintenance, and harvesting techniques. Coffee seeds and seedlings are from natural regeneration. Plant maintenance techniques are carried out by weeding, pruning, organic fertilization, and controlling pests and diseases. The harvest coffee season is generally twice a year. The management of Gayo coffee using an agroforestry system impacts the ecological, economic, and social aspects.

Waduk Jatigede, sebagaimana waduk umunnya, secara horizontal terbagi atas tiga wilayah, yaitu riverin, transisi, dan lakustrin. Perbedaan karakteristik setiap zona juga berdampak pada komposisi dan komunitas fitoplankton, status trofik, dan kandungan karbon. Penelitian ini bertujuan untuk mengalkulasi seberapa besar kandungan karbon pada fitoplankton di perairan Waduk Jatigede pada setiap zona dengan komposisi dan komunitas fitoplankton pada status trofik tertentu. Stasiun penelitian dipilih menggunakan purposive sampling dengan pemilihan stasiun berdasarkan zona dalam waduk, yaitu riverin, transisi, dan lakustrin. Analisis status trofik dan kandungan karbon digunakan untuk mengetahui kondisi dan keberadaan karbon di Waduk Jatiged. Status trofik Waduk Jatigede berdasarkan Indeks Nygaard dan TSI (Tropic State Index) dikategorikan ke dalam tingkat kesuburan eutrofik. Jenis-jenis dari Kelas Cyanophyceae memiliki kelimpahan tertinggi, tetapi kandungan karbon tertinggi berada di kelas Dinophyceae. Zonasi riverin, transisi, dan lakustrin memiliki status kesuburan yang sama, tetapi memiliki komposisi dan komunitas fitoplankton yang berbeda. Berdasarkan hasil penelitian, diperoleh kandungan karbon fitoplankton relatif tinggi di zona riverin dan lakustrin, dan rendah di zona transisi.
Jatigede Reservoir is stagnant inland water formed from the damming of the Cimanuk river. Jatigede Reservoir, like any other reservoir, is horizontally divided into three areas, namely riverine, transition, and lacustrine. The different characteristics of each zone also impact the composition and community of phytoplankton, trophic status, and carbon content. This study aims to calculate the carbon content of phytoplankton in the waters of the Jatigede Reservoir in each zone with the composition and community of phytoplankton at a certain trophic status. The research stations were selected using purposive sampling with station selection based on the site in the reservoir, namely riverine, transition, and lacustrine. Analysis of trophic status and carbon content was used to determine the condition and presence of carbon in the Jatiged Reservoir. The trophic position of the Jatigede Reservoir based on the Nygaard Index and TSI (Tropic State Index) is categorized into the eutrophic level. Species from the Cyanophyceae class tend to have high abundances, but the higher carbon content is in the Dinophyceae class. Riverin, transitional, and lacustrine zoning have the same trophic status but have different compositions and phytoplankton communities. Based on the study results, the carbon content of phytoplankton was relatively high in the riverine and lacustrine zones and low in the transition zone.
