Abstract

The calculation of the added value of using a foaming agent based on sodium lauric and potassium palmitate for palm oil as a peatland fire suppression needs to be studied. This was to determine prospects for further development because it is predicted that peatland fires will continue to recur every year during the dry season. The Hayami method used to analyze the added value of sodium lauric and potassium palmitate as the primary raw materials for foaming agents. The results showed that the production of foaming agents for peatland firefighting applications made from sodium laurate and potassium palmitate of palm oil provided added value with positive criteria, i.e. the ratio of value-added criteria was 80.87% (> 0). In addition to that, the business also provided high-profit categories because the added value category ratio was 80.87% (> 40%). From the analysis of remuneration, it was produced that the foaming agent production business was a capital-intensive since the contribution of the labour income value was 0.89%, other expenses contributed 3.73% and the profit from the entrepreneur as the owner capital of 95.37% which was the largest contribution in providing profit margins. However, the development of a foaming agent production business based on palm oil fatty acids will add new jobs and create new economic impacts in the area of the business locations as well as to increase the amount of palm oil derivative products. Keywords: added value, foaming agent, sodium lauric, potassium palmitate, palm oil

Abstract

Fire is one of the most effective tools in disappearing vegetation community, where it was depend on the characteristics of burning itself and also the performance of the site being burnt. Previous research in mineral soils showed that repeated burning occurred at the same place trend to clean the vegetation which finally leads to have the land with lower number and quality of species left, while in peat land it was not fully understood. The research objective is to understand the vegetation dynamics following peat fires in the fibric peat type at the land preparation area using fire belong to the local community located in the Pelalawan district, Riau province, Indonesia during the dry season in the year 2001. Before slashing and drying, /0 tree species and 4 species of under storey vegetationfound. The site was dominated by Uncaria glabrata at seedling stage, Garcinia rostrata at sapling stage, Shorea macrophylla at pole stage and Pandanus immersus at understorey. After slashing and followed by 4 weeks drying then continued by burning with high flame temperature range from 8750(; to 900°C, it had been found that 3-months follOWing burning the site was dominated by Garcinia-rostrata at seedling stage and Cyperus halpan at understorey, while 6-months following burning the site was dominated by Eugenia jambos at seedling stage and Cyperus hal pan at understorey. Three months following burning species left to be only 4 species with 115 individuaVha (3 species from original and 1 new species emerge), and at 6 months following burning still 4 species left with 250 individuaVha.Meanwhile in understorey vegetation, 3 months following burning the species increased to be 7 species with 746 individuaVha (3 species left unchanged, I species disappeared and 4 new species emerge) and 6 months following burning the species left still 7 species with 1235 individuaVha. This means thatfire stimulate the increasing number of under storey vegetation.

Abstract

Biosekuestrasi atau penyerapan karbondioksida oleh vegetasi merupakan salah satu pengelolaan cadangan karbon yang penting untuk digarisbawahi dalam setiap pertemuan internasional, tetapi ketersediaan data tersebut masih kurang lengkap dan tersebar. Data cadangan karbon dari vegetasi dan tanah gambut sangat penting untuk mengurangi variasi pendugaan stok karbon di hutan gambut. Tujuan penelitian ini adalah untuk memformulasikan persamaan alometrik dalam pendugaan biomassa pohon di hutan gambut primer dan bekas kebakaran serta untuk menganalisis cadangan karbon vegetasi di hutan gambut primer dan bekas kebakaran. Penelitian dilakukan di hutan gambut primer (HGP), hutan gambut bekas terbakar berulang tiap tahun (HG1), hutan gambut bekas terbakar setelah tiga tahun (HG3), dan hutan gambut bekas terbakar setelah delapan tahun (HG8). Klaster plot dibuat di setiap hutan gambut primer dan bekas kebakaran yang mewakili periode kondisi setelah kebakaran dan hutan gambut tidak terganggu. Setiap klaster terdiri dari empat subplot lingkaran (jari-jari 7,32 m) dan empat annular lingkaran (jari-jari 17,95 m). Jumlah total adalah 16 subplot lingkaran serta 16 annular lingkaran. Data cadangan biomassa karbon dikumpulkan dalam plot-plot tersebut.  Hasil penelitian menunjukkan bahwa untuk menduga biomassa total pada keseluruhan klaster, maka persamaan alometrik yang paling tepat adalah Y = 0,061 (DBHxρxT)1,464. Persamaan alometrik umum keseluruhan klaster tersebut digunakan untuk pengguna di lapangan dalam menghitung cadangan biomassa karbon tegakan.  Persamaan umum ini dapat digunakan karena semua klaster penelitian memiliki wilayah zona iklim curah hujan sebesar 2.621-3.339 mm/tahun yang termasuk dalam zona iklim moist 1.500-4.000 mm/tahun (Brown et al., 1989).  Masing-masing persamaan alometrik tiap klaster yang diperoleh dari hasil penelitian ini digunakan untuk menduga cadangan biomassa karbon tegakan tiap klaster.  Persamaan alometrik terpilih penduga biomassa total untuk hutan gambut primer adalah Y = 0,040 (DBHxρxT)1,524; untuk hutan gambut bekas terbakar berulang tiap tahun adalah Y = 0,098 (DBH)2,350; untuk hutan gambut bekas terbakar setelah tiga tahun adalah Y = 0,084 (DBHxρxT)1,376; untuk hutan gambut bekas terbakar setelah delapan tahun adalah  Y = 0,024 (DBHxρxT)1,667. Cadangan karbon total yang merupakan jumlah dari tumbuhan bawah, semai, pancang, tiang, dan pohon adalah sebesar 73,08 tonC/ha di HGP; 4,93 tonC/ha di HG1; 13,64 tonC/ha di HG3; dan 26,13 tonC/ha di HG8.

Abstract

Kebakaran hutan masih menjadi faktor penyebab kerusakan hutan dan lahan di Indonesia. Kejadian kebakaran tidak hanya terjadi di Pulau Kalimantan dan Pulau Sumatera akan tetapi juga terjadi di Pulau Jawa, seperti di Jawa Timur. Penelitian ini bertujuan untuk mengetahui pola sebaran hotspot kebakaran hutan di Taman Hutan Raya Raden Soerjo (Tahura R. Soerjo) Jawa Timur. Metode yang digunakan adalah analisis time series untuk mendapatkan informasi kejadian kebakaran di Tahura R. Soerjo dari tahun 2011- 2015. Hasil penelitian ini menunjukan bahwa hotspot muncul pada bulan Juni sampai November dan mengalami kenaikan pada bulan Agustus. Pola sebaran hotspot pada tahun 2011-2015 dipengaruhi oleh curah hujan dengan nilai R2 9% dan P-value 0,0169. Nilai tersebut menandakan bahwa terdapat hubungan negatif antara curah hujan dan hostpot. Sebaran hotspot didonimasi pada kondisi lereng landai dengan kemiringan 8-15%. Sebaran hotspot terendah ditemukan pada kondisi lereng curam dengan kemiringan 25-45%.

Abstract

Forest is unvaluable resourses which there in have biodiversity as germplas resources, forest product such as wood and non-wood, regulator of the water system, preventing flooding and erosion. Disruption of forest resources is still continues, even it’s increasing in a year to year. That damage caused by forest fires is one part of disruption are becoming more frequent. The negative impact caused by large fires is large enough to covering ecological damage, reduced biodiversity, reduced the economic value of forest and soil productivity, and also global climate change. This study aims to determine the development of natural succession after fires at secondary forest.

Abstract

Land  cover  changes will affect the ecological condition of  the watershed.  Currently, the  conversion of  natural forests into agricultural land has been one of  the main  causes of  deforestation  in  Indonesia. The  changes  could  give impact to  erosion,  increased  run off  and  sedimentation,  loss of  biodiversity,  change of micro  climate,  the release of carbon and Green House Gas (GHG) into the air, etc. This problem has been going on in Watershed Ciliwung.  Forest area, as sources of carbon deposits and carbon absorbents, has limited area along with increasing extents of build up areas. Therefore, it’s estimated the ecological changes will be extended, then will affect the amount of carbon  stocks in Watershed Ciliwung. The objectives of research are  to determine  land cover changes during  the  last twenty years,  to analyze actual carbon stocks in watershed Ciliwung, and to analyze the effect of land cover changes in over twenty years of greenhouse gases, especially CO2. This research used three samples plot on each of the existing land cover. Biomass approach was used in order to estimate carbon stock. Changes in carbon stocks were calculated by using interpolation based on  the actual  carbon  stocks  in 2011. The  research  results  showed  that build up areas was  increased  153,36% during twenty years. The highest potencial carbon stocks was  found in pines forests, which is 144,99 tons/ha. Over the last twenty years, carbon stocks in watershed Ciliwung is declined 42.329,75 tons carbon or 155.350,182 tons CO2e.

Abstract

Land and forest fire can release carbon emissions into the air, for example happened in Central Kalimantan. Especially from land use conversion. Land and forest fire area can be predicted by using hotspot data. Carbon emissions measured by the potential of burnt area on every land covers. This research show that an increase in the number of hotspot from 2000 to 2009. The highest number of hotspot in 2006 reached 22,505 spot. The increasing number of hotspot form 2000 to 2009 is in line with the increasing of burned area on every land covers. Swamp shrub has the highest potential of burned area that reached 113,608.66 ha. Shrub converted to palm oil plantation released the highest carbon emission (801,764 ton). The highest carbondioxide emission on mineral land in Central Kalimantan was released from shrub in 2005 (459,427 ton). While on peat land, the highest carbondioxide emission was released from secondary swamp forest in 2005 (80,851 ton) and primary swamp forest in 2009 (180,531 ton).
