Abstract

Masyarakat lokal memiliki akuntabilitas dan komitmen mengelola sumberdaya dengan pemanfaatan adaptif melalui kearifan lokal. Masyarakat yang hidup didalam hutan memiliki kearifan lokal dalam memanfaatkan lahan hutan khususnya penataan ruang. Pendekatan dalam pemanfaatan ruang yang optimal menggunakan metode query yang tersedia dalam software Arcgis. Metode query merupakan proses analisis yang dilakukan secara tabular karena dapat menyajikan informasi yang lebih spesifik. Dari hasil identifikasi tidak terdapat lahan kelas I. Kelas kemampuan lahan terdiri atas 6 kelas, yaitu kelas II, III, IV, VI, VII, dan VIII. Selain itu penelitiaan ini menggambarkan tentang status daya dukung wilayah berdasarkan pendekatan kebutuhan kalori, kebutuhan fisik minimum serta berdasarkan kebutuhan hidup layak. Daya dukung lahan berdasarkan kebutuhan kalori adalah sebanyak 613 orang/ha/tahun, berdasarkan kebutuhan fisik minimum adalah 5 orang/ha/tahun dan berdasarkan kebutuhan hidup layak adalah 3 orang/ha/tahun. Sehingga daya dukung berdasarkan kebutuhan hidup layak sangat baik. Berdasarkan peruntukkan kawasan hutan dan kemampuan lahan, terdapat 41.037,86 hektar atau 16,03 % dari wilayah adat Kecamatan Long Pahangai yang dapat dijadikan sebagai lahan budidaya berupa pertanian intensif, perkebunan, hutan desa, hutan kemasyarakatan dan hutan tanaman rakyat sedangkan terdapat 212.332.06 hektar atau 82,94 dari wilayah adat Kecamatan Long Pahangai yang dapat dipertahankan fungsinya sebagai kawasan lindung tetapi juga dapat dimanfaatkan hasil hutan bukan kayunya secara terbatas dengan bentuk konservasi.

Abstract

Pertumbuhan tegakan adalah pertambahan (riap) dari suatu besaran seperti tinggi, diameter, volume atau luas bidang dasar pohon dalam periode tertentu. Model pertumbuhan digunakan untuk menduga besaran produktivitas dan sangat berguna dalam perencanaan pengelolaan hutan tanaman suatu jenis pohon. Kajian model pertumbuhan jenis Eucalyptus urograndis telah di lakukan tahun 2009 di PT Toba Pulp Lestari, sektor Aek Nauli, Sumatera Utara pada rotasi 1 dan rotasi 2 dengan tujuan untuk membandingkan pertumbuhan jenis tersebut antara rotasi 1 dan rotasi 2, dan menentukan daur volume optimalnya. Kajian dilakukan dengan menggunakan data dari PSP (Permanent Sample Plots) yang diukur secara periodik dan data hasil pengukuran sesaat pada TSP (Temporary Sample Plots) dari berbagai umur tegakan. Hasil kajian mendapatkan bahwa pendugaan pertumbuhan jenis E. urograndis dapat mengikuti persamaan tinggi (H), diameter (D) dan volume (V) sebagai berikut : ln H = 3,40434 - 1,73745 (1/umur); ln D = 2,99598 - 1,56925 (1/umur); ln V = 6,300505 - 5,63547 (1/umur) dengan daur volume optimal dicapai pada tahun 5,5 tahun untuk rotasi 1 dan persamaan : ln H = 3,342944 - 1,5336 (1/umur); ln D = 2,987992 - 1,44311 (1/umur) dan ln V = 6,205122 - 5,06804 (1/umur) dengan daur volume optimal dicapai pada tahun ke 5 untuk rotasi 2. Model pertumbuhan dan teknik yang sama dapat digunakan untuk jenis E. urograndis pada kondisi lingkungan yang relatif sama.

Abstract. Gunung Leuser National Park (GLNP) in Aceh and North Sumatra, Indonesia was allocated to protect and preserve its local biodiversity. GLNP implements a national park management policy that adopts a zoning system which includes core, wilderness, rehabilitation, traditional use, utilization and other zones. Population growth causes land cover changes in GLNP and in its buffer zone. One of the approaches to assessing rapid land cover changes is by employing a remote sensing approach. The purposes of this study are: (1) to analyze land cover change between the periods of 1996, 2005 and 2014; (2) to analyze the relationship between the population pressure index and land cover changes; and (3) to propose a guidance and recommendations for a better management of land cover changes in GLNP.  The results showed that the main land cover classes at GLNP and its buffer zone in the period between 1996 and 2014 were forests, grass/shrubs, and cropland. Compared with the proposed zoning and the provincial master plan, there were land cover mismatches in 2014, especially in Southeast Aceh Regency. The land cover changes analysis indicated a significant decrease of forest land cover from 1996 to 2014. In the period between 1996 and 2005, the analysis showed the highest increase for cropland whilst in the period between 2005 and 2014, the highest increase was observed for plantations.Keywords. Gunung Leuser National Park, land use/land cover change, population pressure index.Abstrak. Fungsi utama dari Taman Nasional Gunung Leuser (GLNP), sebagai salah satu dari kawasan konservasi yang ada di Provinsi Aceh dan Provinsi Sumatera Utara, adalah untuk melindungi dan melestarikan sumberdaya keanekaragaman hayati yang terdapat di dalamnya. Sebagai Taman Nasional, GLNP memiliki kebijakan pengelolaan yang harus didasarkan pada sistem zonasi yang terdiri dari zona inti, rimba, rehabilitasi, penggunaan tradisional, pemanfaatan dan zona- zona lainnya. Peningkatan jumlah penduduk menyebabkan perubahan  penutupan lahan di kawasan GLNP dan zona penyangganya. Salah satu pendekatan yang dapat dilakukan untuk mengetahui perubahan penggunaan lahan secara cepat adalah menggunakan teknik penginderaan jauh. Untuk itu, tujuan dari penelitian ini adalah: (1) Untuk menganalisis perubahan penutupan lahan pada tahun 1996, 2005 dan 2014; (2) Untuk menganalisis hubungan antara indeks tekanan penduduk dengan perubahan penutupan lahan; dan (3) Untuk menyusun arahan dan rekomendasi pengendalian perubahan penutupan lahan yang mendukung pengelolaan GLNP. Hasil penelitian menunjukkan bahwa bentuk penutupan lahan paling besar di GLNP dan zona penyangga pada periode 1996-2014 adalah hutan, rumput/semak belukar dan pertanian lahan kering. Terdapat ketidaksesuaian penutupan lahan tahun 2014 dengan peta zonasi yang telah dibuat dan juga ketidaksesuaian penutupan lahan tahun 2014 dengan Rencana Tata Ruang Wilayah (RTRW) Provinsi Aceh dan Sumatera Utara terutama di Kabupaten Aceh Tenggara. Hasil analisis perubahan penutupan lahan menunjukkan penyusutan penutupan lahan paling tinggi terjadi pada hutan pada periode tahun 1996-2005 dan periode 2005-2014. Pada periode tahun 1996-2005 peningkatan penutupan lahan paling tinggi terjadi pada pertanian lahan kering sedangkan untuk periode tahun 2005-2014 peningkatan penutupan lahan paling tinggi terjadi pada perkebunan.Kata kunci. indeks tekanan penduduk, perubahan penutupan lahan, Taman Nasional Gunung Leuser.

Abstract

Various natural disasters such as floods and landslides that much happening at this time caused by environmental damage, esppecially upper watershed damage. Actual land use of forests in the Upper Citarum Watershed area is only 16.20%, still not meet the minimum area of forest (30%) base on UU No. 41/1999 about Forestry. Actual land use configuration in study site causes most of the region is dominated by the level of erosion hazard very heavy; total RTH covering 76.75% total study site; and approximately 58.25% of farmer households unable to meet minimum standards for decent living needs. By applying a multiple target linear optimization model Linear Goals Programming (LGP) that solved by General Algebraic Modeling System (GAMS) optimization software, recommended the optimal configuration of land use that can meet the ecological and economic objectives. These recommendations can decrease the erosion rate of 94.13% and reaching 72.97% areas that meet standards of TSL; reaching an area covering 87.39% of RTH; and increasing aggregate sector of food crops, plantations, and forestry farm household income amount 220.83%. Optimization model in this study are static models that do not pay attention to time, but this models produces marginal values and we can analyze the value of elasticity (Sensitivity Analysis) that can be known implications for optimization purposes in case of changes in conditions of objective optimization.

Abstract

The Comparison of Carbon Stocks on Some Land Cover at Paser, East Kalimantan Based on Its Soil Physical and Soil ChemicalForest has a lot of direct and indirectly benefits for life. Direct benefits of forest are timber, non timber forest products and wildlife/fauna. While, indirect benefits of forest are the environment services as the hydrology regulator, aesthetic function, producer of oxygen and carbon absorber. Forest is the largest carbon absorber (sinks) and having an important part in the global carbon cycles, however forest can also produce a carbon emission (source). Forest ecosystem has ability to absorb and store different kinds of carbon even in the natural forest, mangrove, swamp, forest plantation and at the folk’s forest. The differences of carbon sinks are influenced by number and tree density, trees species, biotic factors which consist of radiation, humidity, temperature and soil fertility which affect the rate of photosynthesis. The land fertility was determined by soil physical, soil chemical, and soil biological. Therefore, this research aims to compare carbon stocks on some land cover based on its soil physical and soil chemical.The research was performed at some lands coverings of Paser, East Kalimantan in January to July 2011. Data was processed and analyzed in the Forest Influence Laboratory, Department of silviculture, Faculty of Forestry, Bogor Agriculture University and Land Laboratory, Land Research Hall. Measurement of biomass and carbon sinks were performed by using the diameter data of stand and height in each land covering. Analysis of soil physical temper (texture and soil bulk density) and soil chemical (pH, CEC, Ratio of C/N, P, K, Ca, and Mg) were performed to disturbed and undisturbed soils. The result of research  showed that mangrove forest had the greatest carbon sinks, that was 51.5031 tons/hectares. While, the lowest carbon sinks was on the palm oil plantation for 0.1046 tons/hectares. From soil analysis result was  known that swamp forest tended to be more fertile compared with other land coverings. Whereas, palm oil plantation and agroforestry is indicated the lower of land fertility. The raising of soil physical and soil chemical’s value increase the carbon stocks on each land cover, exception of bulk density that decrease the carbon stocks. The result analysis correlation showed in insignificant value, its indicated by the value of r2 less than 99%(0,99) or 95%(0,95). Need to research about estimation carbon stocks on the other land cover, and compare the carbon stocks based on the other land characteristics, as topography and climate.
