Abstract

Hutan rawa gambut telah diakui sebagai ekosistem yang mampu menyimpan karbon hingga jumlah besar. Riset ini membahas pengembangan model estimasi massa karbon menggunakan data penginderaan jauh aktif. Tujuan penelitian ini adalah  mendapatkan informasi hasil untuk pengembangan  model estimasi volume massa karbon dengan menggunakan penginderaan jauh aktif, data ALOS PALSAR. Model dikembangkan atas dasar hubungan antara massa karbon rata-rata dan nilai backscatter ALOS PALSAR dari HH, HV dan band sintetik  HH/HV yang berasal dari berbagai ukuran pixel, yaitu : (a) 1 x 1 pixel, (b) 3 x 3 pixel dan (c) 5 x 5 pixel. Studi ini menemukan bahwa koefisien korelasi yang baik ditunjukkan antara nilai backscatter dan stok karbon. Penelitian ini juga menunjukkan bahwa korelasi terbaik diberikan oleh HV, korelasi tersebut lebih   baik   daripada   korelasi   yang   diperoleh   dengan   menggunakan   HH   dan   HH/HV.   Studi   ini mengidentifikasi model terbaik, yaitu ŷ = -5,337HV2– 111,8HV – 480,1;  R²=0,86 dan 3 x 3 pixel

Abstract

Taman Nasional Bukit Barisan Selatan (TNBBS) memiliki ekosistem yang lengkap mulai dari hutan dataran rendahtermasuk hutan mangrove hingga hutan dataran tinggi. Taman nasional ini teridentifikasi sebagai area konservasiprioritas utama untuk harimau sumatra (Tiger Conservation Unit 1). Akan tetapi, banyak tutupan hutan yang digunduli (deforestasi). Deforestasi bukan hanya menjadi ancaman besar bagi kelestarian hutan tetapi juga terhadappopulasi harimau sumatra. Penelitian ini menghubungkan data citra satelit Landsat dengan data survei harimaumenggunakan kamera otomatis (camera traps) untuk mengetahui pola deforestasi, populasi harimau, dan implikasideforestasi terhadap populasi harimau. Hasil penelitian menunjukan sekitar 27% tutupan hutan di TNBBS telahhilang. Rata-rata laju deforestasi dalam satu dasawarsa terakhir (1998 - 2006) sebesar 18,76 km2/tahun. Jumlahharimau menurun dari 57 individu pada tahun 1998 menjadi 22 individu di tahun 2006, dan kepadatan populasinyajuga menurun dari 2,25 individu/100km2 menjadi 1.16 individu/100km2. Harimau di TNBBS memilikihabitat yang bervariasi mulai dari hutan dataran rendah termasuk mangrove ikutan hingga dataran tinggi.Kata Kunci: Deforestasi, Mangrove, Camera Trap, Citra Satelit, Harimau Sumatra, Taman Nasional Bukit BarisanSelatan

Abstract

This study describes on development of habitat suitability for Sumatran tiger in Bukit Barisan Selatan National Park (BBSNP). In this study remotely-sensed data set were linked with tiger and it prey survey using camera trap to identify the environmental and human factors that influences the tigers potential habitat, and to develop a spatial model as well as in BBSNP. All at once, the study showed that the potential model for estimating the tigers potential habitat suitability could be developed using environmental and human factors. The most significant factors that influence the tiger habitat suitability in Bukit Barisan Selatan National Park are human factors such as distance to road and distance to forest edge and the environmental factor i.e. the number of tiger prey. The verification of the model shows that the model is capable to estimate the probability of the tiger presence having accuracy of approximately 78%. The model shows that there is no significant difference between the predicted data and actual data and having mean deviation less than 10%.

Abstract

Nowadays, the quality of urban environment is a challenging problem. Urban development indicated by the increase of population as well as development in all aspects, either positive or negative. But it can degrade the environment quality. This can be indicated by for example, air pollution, which can reduce the oxygen supply and overwhelms the production of carbon dioxide as well as the increase in temperature. From the foregoing problems, the “back to nature” concept is needed to solve environment problem in urban area, by introducing the urban forest. However, constraints in available space exists, therefore, alternative solution can be employed by increasing the effectiveness of existing urban forest. This research aims at analyzing the effectiveness of urban forest in reducing the air temperature based on two parameters: forest structures and forest forms. Keywords: Urban Forest, Temperature Reduction, Forest Structure, Forest Forms, GIS Analysis. ABSTRAKKualitas lingkungan perkotaan, akhir-akhir ini, merupakan masalah yang menantang. Perkembangan perkotaan selalu mengindikasikan dengan pencemaran udara dan perkembangan di segala bidang, yang berdampak positif maupun negatif. Namun demikian, perkembangan ini dapat menurunkan kualitas lingkungan. Hal ini dapat diindikasikan misalnya polusi udara, yang dapat menurunkan jumlah oksigen dan meningkatkan jumlah karbon dioksida yang juga terindikasikan dengan naiknya suhu udara perkotaan. Dari berbagai masalah lingkungan tersebut, konsep kembali ke alam dibutuhkan untuk mengatasi masalah lingkungan perkotaan, dengan mengenalkan konsep hutan kota. Namun, banyak pembatasan-pembatasan termasuk lahan yang tersedia, sehingga solusi yang dapat meningkatkan efektivitas hutan kota dibutuhkan. Penelitian ini menganalisa efektivitas hutan kota dalam menurunkan suhu udara perkotaan berdasarkan dua parameter: struktur hutan dan bentuk hutan.Kata Kunci: Hutan Kota, Penurunan Suhu Udara, Struktur Hutan, Bentuk Hutan, Analisa SIG.

Abstract

In the last 2 decades, forest and land fires in Indonesia have become a serious problem at national, regional, and even international levels. The smoke of the fires gave a negative impact on human activities and health and in turn coused economical and social loss. In addition, the haze pollution has become a serious problem internationally. This study was conducted to establish a risk model of forest and land fire in Kapuas tengah watershed, Kalimantan Barat Province. The model was based on scoring and weighting of bio-phisycal and human activity factors. Rangking method and Composite Mapping Analysis (CMA) were used to establish the model. The result showed that the accuracy of model by ranking method to determine the risk level and zone of forest and land fire was only 62,4% in Kapuas Tengah watersheed. Therefore, the model was not good enough to represent actual condition in the field. The accuracy of model using CMA method could be used to determine risk level and zone of forest and land fire. The CMA method showed that the Kapuas Tengah watershed consisted of 1,051,029.4 ha high risk, 379,307.0 ha of moderate and 195,010.7 ha of low vulnerable. The risk map can be used for early warning system to prevent forest and land fires.Keywords: forest and land fires, composite mapping analysis, rangking method, fire risk map

Abstract

This study describes the use of multitemporal  principal component analisys (MPCA), vegetation index differencing (VIDN) and  conventional maximum likelihood classifier (MLC) for  detecting landslides.  The study found that the synthetic images derived from stable greenness, delta greenness and delta brightness of MPCA summarized the information of landslides effectively producing accuracy of 88% for Teradomari and 91% for Tochio and Shitada Mura.  The VIDN provides relatively lower accuracies than those from MPCA, i.e., only 62.5% for Teradomari and 64% for Tochio and Shitada Mura. The MLC method also provided very low user’s accuracy, i.e. 56.9% for Teradomari and 63.7% for Tochio and Shitada Mura but high producer’s accuracies, i.e. 100% for Teradomari and 98.3% for Tochio and Shitada Mura. The study also found that the landsides that could be detected should be more than the size of spatial resolution of the SPOT imagery, i.e. 10 m x 10 m. Detecting landslides using SPOT imagery is more efficient than using only ground survey, providing an efficiency of 2.7.
