Abstract

ABSTRACTEstimation of carbon stock has direct limitations related to the speed of obtaining results, area coverage and high cost. Remote sensing can be used to estimate carbon stocks with an adequate level of accuracy. The objectives of this study are 1) to obtain the potential carbon storage of A. mangium, 2) to estimate model of carbon stocks based on a radar image (backscatter value of Alos Palsar), and 3) to map potential carbon stock distribution of A. mangium at PT. Inhutani II, South Kalimantan. The method used was a direct inventory of carbon stocks by making 69 measuring plots (0.1 ha area of each plot) spread across several age. The field inventory results were used to formulate a relationship with the polarization values of the Alos Palsar. The results showed that the potential surface carbon deposit varied from 32.03 to 46.10 tons/ha with an average value of 39.06 tons/ha. The total potential carbon stock per ha ranged from 35.48 to 51.01 tons/ha with an average of 43.24 tons/ha. The best allometric relationship between carbon stock and the polarization values HH and HV of the Alos Palsar image was Carbon Deposit = 292 + 2.00 HH2 + 27.1 HV with the R2  = 40.9%. Potential carbon storage based on Alos Palsar image ranged between 40 - 80 tons/ha. The result of Alos Palsar predicton is accurate so the technology can be used for measuring or monitoring of carbon stocks in plantation forest.ABSTRAKPendugaan persediaan karbon secara langsung mempunyai keterbatasan terkait dengan kecepatan memperoleh hasil, cakupan luasan yang terbatas dan biaya yang mahal. Penginderaan jarak jauh dapat dimanfaatkan untuk menduga persediaan karbon dengan akurasi yang cukup memadai. Tujuan penelitian ini yakni: 1) mendapatkan potensi simpanan karbon jenis A. mangium, 2) mendapatkan model penduga simpanan karbon berdasarkan citra Radar (nilai backscatter citra Alos Palsar), 3) mendapatkan peta sebaran potensi simpanan karbon jenis A. mangium di PT. Inhutani II, Kalimantan Selatan. Metode yang digunakan dengan melakukan inventarisasi persediaan karbon secara langsung yakni pembuatan plot pengukuran sebanyak 69 plot dengan luas masing-masing plot seluas 0,1 Ha tersebar pada beberapa umur. Hasil inventarisasi tersebut digunakan untuk membentuk hubungan dengan nilai polarisasi dari citra Alos Palsar. Hasil penelitian menunjukkan potensi simpanan karbon permukaan sebesar 32,03 - 46,10 ton/ha dengan rata-rata 39,06 ton/ha. Potensi simpanan karbon total per Ha berkisar antara 35,48 -51,01 ton/ha dengan rata-rata 43,24 ton/ha. Model alometrik terbaik hubungan antara simpanan karbon dan nilai polarisasi HH dan HV dari citra Alos Palsar adalah Simpanan karbon = 292 + 2,00 HH2 + 27,1 HV dengan koefisien determinasi sebesar 40,9%. Potensi sebaran simpanan karbon total terbesar berdasarkan aplikasi citra Alos Palsar yakni berkisar antara 40 - 80 ton/Ha. Penggunaan Alos Palsar untuk menduga simpanan karbon menghasilkan dugaan yang cukup akurat sehingga teknologi ini dapat digunakan untuk mengukur atau monitoring persediaan karbon pada tegakan hutan tanaman.

Abstract

The accurate information derived from high accuracy of remote sensing imagery analyses coupled with field observation data are required to develop a sound forest management. The study is mainly emphasized on assessment of the capabilities of remote sensing imageries to identify ecosystem types within the transitional  ecosystem. Since, the predominant transition ecosystems found within the study area were secondary forest, rubber jungle, rubber, oil palm plantation, and also other land cover such as mixed plantation and shrubs,  therefore,  the models developed were focused for those ecosystem types.  Prior to any further analysis, this study was initiated  to develop the biomass estimation model using 50 m resolution of ALOS PALSAR image in transition ecosystem, Jambi Province. Biomass models were developed by analyzing the relationship between  backscatter magnitude and field biomass. Backscatter magnitude from 1 polarization images, namely HH,  HV, and one additional band of  ratio of HH/HV  were analyzed simultaneously with  field biomass. The best models established are AGB = 42,069 exp (0.510 HV) and AGB = 1,610 exp (-0.02 HV²) with R² of 52.3% and 50,8%, respectively. The models are then used to map out the biomass distribution within the transition ecosystem and to identify the factors affecting the magnitude of biomass content for all transition ecosystem types.

Abstract

Kajian ini bertujuan untuk merumuskan strategi kebijakan pengembangan model gasifikasi listrik berbasis biomasa di daerah-daerah pinggiran, melalui pembangunan Hutan Tanaman Energi (HTE).  Data primer dan sekunder diolah dengan regresi logit, gap analysis dan dirangkum dalam permodelan sistem dinamis. Hasil analisis menunjukkan bahwa masyarakat sangat bergantung pada listrik dan produknya dan bersedia untuk membayar lebih akibat adanya listrik. Jika hutan tanaman dialokasikan untuk menyediakan biomasa yang akan digunakan untuk listrik maka strategi utama yang harus disiapkan adalah menjamin kepastian harga beli bahan baku biomasa sehingga menjamin kelayakan usaha pemegang ijin hutan tanaman.  Pengembangan biomasa terutama kaliandra dipandang penting karena mampu menyediakan energi primer yang berdasarkan kajian ini masih jauh antara rencana dengan realisasi.  Rasio elektrifikasi akan lebih cepat tercapai jika hutan tanaman energi dengan jenis kaliandra dikembangkan dengan serius. Untuk itu, strategi yang sesuai adalah menjamin harga bahan baku di angka Rp 400.000/ton dan pengaturan intensitas panen. Strategi pemungkin lain adalah subsidi untuk instalasi pembangkit listrik gasifikasi.

Abstract

Guludan technique becomes an alternative for mangrove rehabilitation in the disused fishponds. This technique has been implemented since 2005 on the coast of Jakarta. The wider application of this technique requires several studies in advance to see growth of the mangrove in the already planted guludan. This study aims to measure the growth of mangroves planted by guludan techniques, identify environmental factors that affect their mangrove growth, and analyze their relationship. Measurements were performed on 40 guludan samples which planted by Rhizopora mucronata in 2010 - 2013. Rhizopora mucronata grew well in the guludans, followed by Sonneratia caseolaris that grew naturally. Both were dominated by individuals in sapling phase. Meanwhile, environmental factors affecting mangrove growth were N-total, P, Mg, Ca, Na, clay texture, CEC, soil salinity, soil pH, and water level in the guludan.Keywords: guludan technique, mangrove rehabilitation, Rhizophora mucronata, Sonneratia caseolaris

Abstract

Perubahan iklim merupakan isu yang hangat saat ini dan mengakibatkan terjadinya perubahan ekosistem secara global. Daerah aliran sungai (DAS) ciliwung adalah salah satu DAS kritis di indonesia dan menjadi DAS prioritas berdasarkan Kepermenhut No.SK.328/Menhut-II/2009. DAS ciliwung rentang terhadap perubahan iklim, terutama suhu dan curah hujan. Kerentanan DAS ciliwung berpengaruh terhadap kerentanan masyarakat di DAS ciliwung , oleh karena itu, tujuan penelitian ini adalah untuk menilai kerentanan masyarakat terhadap perubahan iklim di DAS ciliwung. penilaian kerentanan masyarakat terhadap dilakukan selama hampir 9 bulan dari bulan April-desember 2009. Penilaian kerentanan masyarakat terhadap perubahan iklim menggunakan 3 karakteristik kerentanan, yaitu: singkapan, kepekaan, dan kemampuan adaptasi. Kriteria dan indikator singkapan menggunakan hasil referensi KNLH (1998) atau Indeks penggunaan air. sedangkan kepekaan dan kemampuan adaptasi mencakup selutuh aspek kehidupan sosial yang meliputi sosial, ekonomi, SM, fisik, dan alam. Penilaian kerentanan menggunakan proses hirarki analisis (AHP) dan sistem informasi geografi (SIG). Hasil penelitian menunjukan bahwa tingkat kerentanan masyarakat terhadap perubahan iklim di DAS ciliwung berbeda secara spasial. Kerentanan masyarakat di DAS ciliwung jilir termasuk ke dalam kelas medium dengan indeks 0,94. Sedangkan DAS ciliwung hulu dan tengah dikategorikan dalam kelas agak rendah dengan nilai indeks 0,16 dan 0,11. Perunahan iklim tidak bisa dicegah secara tuntas sehingga diperlukan adaptasi terhadap perubahan iklim. Strategi adaptasi terhadap perubahan ilklim dapat dilakukan dengan pengelolaan hutan secara lestari.

Abstract

The aim of this study was to identify the spatial pattern of biomass distribution in the revegetation of the post-mining area in PTVI. The nearest neighbour analysis method by comparing the distance of an individual was used to determine the spatial biomass distribution pattern in the post nickel mining revegetation area of PTVI. The nearest neighbour analysis was used to explain the distribution pattern of locations using a calculation that considers the distance, number of locations and acreage. This analysis produced a final result in the form of an index ranging from 0 until more than 1. It can be explained as NNI 1, clustered spatial pattern, NNI = 1, random spatial pattern and NNI 1 dispersed spatial pattern. This research was found that there are clustered (K1, K2, K3) and dispersed patterns (K4) of biomass spatial distribution patterns in PTVI’s post nickel mining revegetation area.Keywords: post-mining, revegetation, biomass, spatial distribution pattern

Abstract

The characteristic of land and forest fires occurred in Indonesia are varied widely, following the variation of time within a year and geographic location. This paper describes how the spatio-temporal of forest and land fire typology was developed. The main objective of this study was to develop a spatio-temporal typology of forest and land fire by considering several key indicators that directly related to the density of active fire occurrence, such as percentage of forest area (x1), population density (x2), ratio of forest area to population (x3), ratio of plantation area to population (x4), ratio of agriculture area to population (x5), GRDP (x6), population growth (x7), deforestation growth (x8), plantation growth (x9) and dry agriculture growth (x10) as well as  MODIS-based fire hotspot. The typology analysis was performed using clustering techniques with Euclidean distance dissimilarity measure, where the grouping process was drawn with single linkage method. The temporal analysis showed that the highest occurrence of the fire hotspot was mainly found in the third quarter. It was found that the forest and land fire typology could be developed into three classes using variables x6 and x7 with overall accuracy of 78.15% or x1-x6-x7 with overall accuracy of 78.8%.  No accuracy improvement was obtained when the typology was developed using five variables x1-x3-x4-x6-x7.

Abstract

Bogor, Cianjur, and Sukabumi areas of West Java Province, Indonesia, are vulnerable landslide areas. This study analyzes the landslide characteristic and the factors affecting landslides. The analysis was carried out on 148 landslides from 415 of 2018-2020 landslides, which were selected purposively by considering the heterogeneity of soil, geology, slope classes, land use type, and accessibility of landslide locations. Landslide characteristics and factors affecting landslides were analyzed using frequency analysis and binary logistic regression. The results showed that the most dominant characteristics of surface and shallow landslides were the landslides characterized by slopes >45%, Quaternary geological period, Andisol soil type, agriculture land use type, the occurrence of rain, and absence of earthquake. The dominant factors affecting surface and shallow landslides are human activities in land use, soil properties, steep-very steep slopes, Inceptisol and Entisol soil orders, young rocks (Quaternary geological period), rainfall events, and high earthquake magnitude.
