Hutan (Studi Kasus: PT. Kallista Alam)
Abstrak: Penilaian ekosistem akibat kerusakan lingkungan hidup merupakan hal yang penting bagi ilmu pengetahuan dan perumusan kebijakan. Masalah utama yang menjadi kelemahan penilaian ekosistem adalah double counting dan relevansi item. Double counting adalah perhitungan yang dilakukan dua kali. Relevansi adalah keterkaitan atau hubungan pokok masalah dengan solusi yang dihadapi. Perhitungan seperti ini menyebabkan pembengkakan nilai dari nilai yang seharusnya. Kelemahan penilaian kerugian ekosistem di Indonesia terjadi pada Peraturan Menteri Lingkungan Hidup Nomor 13 Tahun 2011. Kasus kebakaran hutan lahan gambut yang terjadi di areal PT. Kallista Alam tahun 2014 seluas 1000 ha merupakan salah satu contoh kasus yang cukup merugikan. Penerapan peraturan penilaian ekosistem pada kasus kebakaran di areal PT. Kallista Alam mengandung kelemahan, seperti double counting dan irrelevant item yang disebabkan oleh kompleksitas ekosistem, jasa ekosistem yang saling melengkapi, dan sistem klasifikasi jasa ekosistem yang tidak konsisten. Sebaiknya dalam penilaian ekosistem lebih mengenal ekosistem dan layanan ekosistem agar terhindar dari double counting dan irrelevant item., Ecosystem assessment due to environmental damage is important for science and policy formulation. The main problem that becomes the weakness of ecosystem assessment is double counting and item relevance. Double counting is a calculation that is done twice. Relevance is the relationship between the main problem and the solution. This kind of miscalculations causes the value becomes bigger than it should be. The weakness on assessing ecosystem loss in Indonesia occurs in the Minister of Environment Regulation No. 13 of 2011. The case of peatland forest fire that happened on the 1000 hectares area of PT. Kallista Alam is an example of case that is quite detrimental. The application of the ecosystem assessment at the PT. Kallista Alam’s case has several weaknesses such as double counting and irrelevant item that caused by ecocystem complexity, ecosystem service that complete each other, and inconsistent classification of ecosystem services. The ecosystem assesement would be better if it can avoid the double counting and irrelevant item by knowing more about the ecosystem and its services.

Abstrak: Uncontrolled land and forest fires have caused an enormous environmental losses in terms of economical, ecological and political aspects. The main objective of this study is to formulate and evaluate the method of economic valuation of environmental damage caused by land and forest fires. The study was conducted in the National Park of Bukit Baka (230 ha), Natural Recreation Park of Baning (59.5 ha), Industrial Forest Plantation of Finantara Intiga (15 ha), Industrial Forest Plantation of Inhutani III (12,452 ha), TCSDP Plantation of Nanga Pinoh (76 ha) and community plantation (91.20 ha) with the sample of 42 ha and 250 respondents. The data analysis used were the approach of market price, productivity, shadow price, replacement cost, income losses, health costs, transfer benefit, contingent valuation method, canonical correlation, structural equation model and system analyses. The study showed that land and forest fires give different impacts. Therefore, the choice of methods should be in accordance with criteria and stages of valuation. The total economical losses caused by fires in 1997 was 53.91 billion rupiahs which was 175 million rupiahs in the sample area or of 4.17 million rupiahs/ha in the average. It was an increasing of 69.64% in the year of 2003. The biggest loss occurred in the forest area with conservation and natural preservation functions. On the other hand, in terms of the benefit, the biggest loss was in the direct benefit. It is because not all indirect benefit was valuated in this study. The declining of people’s health was the biggest loss in terms of haze from land and forest fires. However, those fire impact did not disturbed the cooperation with other countries but only the transaction costs. Both of the natural and human factor influence of land and forest fire simultaneously with ã = -0.192 and ã = -0.462. Rainfall, temperature, humidity, the using of fire, attention and involving of the community toward fire and mitigation effort showed the most significant effect on forest fire (á = 0.05) with 73% of model validity level. Therefore, the alternatives of policy to prevent land and forest fires are the implementation of optimistic scenario by preventing the using of fire, the improvement of fire mitigation efforts, ratification of AATHP and strengthening the cooperation with other countries in controlling land and forest fires.
