Abstract

Saharjo BH, Sudo S, Yonemura S, Tsuruta H (2010) Fuel characteristics and trace gases produced through biomass burning. Biodiversitas 11: 40-45. Indonesian 1997/1998 forest fires resulted in forest destruction totally 10 million ha with cost damaged about US$ 10 billion, where more than 1 Gt CO2 has been released during the fire episode and elevating Indonesia to one of the largest polluters of carbon in the world where 22% of world’s carbon dioxide produced. It has been found that 80-90% of the fire comes from estate crops and industrial forest plantation area belongs to the companies which using fire illegally for the land preparation. Because using fire is cheap, easy and quick and also support the companies purpose in achieving yearly planted area target. Forest managementand land use practices in Sumatra and Kalimantan have evolved very rapidly over the past three decades. Poor logging practices resulted in large amounts of waste will left in the forest, greatly elevating fire hazard. Failure by the government and concessionaires to protect logged forests and close old logging roads led to and invasion of the forest by agricultural settlers whose land clearances practices increased the risk of fire. Several field experiments had been done in order to know the quality and the quantity of trace produced during biomass burning in peat grass, peat soil and alang-alang grassland located in South Sumatra, Indonesia. Result of research show that different characteristics of fuel burned will have the different level also in trace gasses produced. Peat grass with higher fuel load burned produce more trace gasses compared to alang-alang grassland and peat soil.Key words: peat soil, peat grass, alang-alang, biomass burning, trace gas.

Abstract

Biomass burning is the burning of the world’s living and dead vegetation, including grasslands, forests and agricultural lands following the harvest for land clearing and land-use change. One of the important information needed following this biomass burning is how long the burnt forest or land can be recovered, and how worst the changing occurred. Repeated burning occurred at the same place trend to clean the vegetation which leads to have the land with lower number and quality of species left. The research objective is to understand the vegetation changing following peat fires in the sapric peat type at the land preparation using belong to the local community located in the Pelalawan district, Riau province, Indonesia during the dry season in the year 2001. Before burning, logging, slashing, drying and burning the site was dominated by Uncaria glabrata at seedling stage, Ficus sundaica at sapling stage, Ficus sundaica at pole stage and Stenochlaena palustris at understorey. After logging, slashing and followed by 4 weeks drying then continued by burning with high flame temperature range from 900-1100oC, it had been found that 3-months following burning the site was dominated by Uncaria glabrata at seedling stage and Nephrolepis flaccigera at understorey while 6-months following burning the site was dominated by Parastemon uruphyllus at seedling stage and Erechites valeriantifolia at understorey stage. © 2006 Jurusan Biologi FMIPA UNS Surakarta Key words: peat fires, peat type, flame, natural regeneration, human.

Abstract

During dry season it is easily recognized that smoke will emerge at certain place both in Sumatra and Kalimantan that is in peatland. The worst situation occurred when fire burnt buried log in the logged over area where the fire fighter did not have any experience and knowledge on how to work with fire in peatland. Finally it had been found that one of the reasons why firefighter failed to fight fire in peatland is because they do not have any knowledge and experience on it. In order to know the fire behavior characteristics in different level of peat decomposition for fire management and sustainable management of the land for the community, research done in Pelalawan area, Riau Province, Indonesia, during dry season 2001. Three level of peat decomposition named Sapric, Hemic, and Fibric used. To conduct the research, two 400 m2 of plot each was established in every level of the peat decomposition. Burning done three weeks following slashing, cutting and drying at different time using circle method. During burning, flame length, rate of the spread of fire, flame temperature and following burning fuel left and the depth of peat destruction were measured. Results of research shown that in sapric site where sapric 2 has fuel load 9 ton ha-1 less than sapric 1, fire behavior was significantly different while peat destructed was deepest in sapric 2 with 31.87 cm. In hemic site where hemic 2 has fuel load 12.3 ton ha-1 more than hemic 1, fire behavior was significantly different and peat destructed deeper than hemic 1 that was 12.6 cm. In fibric site where fibric 1 has fuel load 3.5 ton ha-1 more than fibric 1, fire behavior was significantly different that has no burnt peat found. This results found that the different fuel characteristics (potency, moisture, bed depth, and type) at the same level of peat decomposition will have significantly different fire behavior as it happened also on the depth of peat destruction except fibric. The same condition occurred in the fire behavior at different level of peat decomposition. Key words: Fire, fuel, peat, sapric, hemic, fibric, Pelalawan.

Abstract

Thoha AS, Saharjo BH, Boer R, Ardiansyah M. 2019. Characteristics and causes of forest and land fires in Kapuas District, Central Kalimantan Province, Indonesia. Biodiversitas 20: 110-117. Forest and land fire occurs almost every year in Indonesia. Its impact is very harmful for human and environment. Developing a program in fire management requires identification of forest and land fire characteristics and its causes. The aim of this research was to evaluate the characteristics and causes of forest and land fire in Kapuas District Central Kalimantan Province. Spatial analysis of hotspots with rainfall was used to determine temporal distribution of fire. Spatial distribution between hotspot and causative factors was determined to identify spatial characteristics of fires. Increasing number of hotspots occurs when monthly rainfall decreases. Most high fire activities are located in peatland, swamp shrubs, close to road, close to river and far away from villages. Fire causes from human activities mostly originated from swamp shrub burning and land clearing for farming. Hotspot density has various relationship with peat depth, land cover, accessibility, and human activities.

Abstract. Wasis B, Saharjo BH, Putra EI. 2019. Impacts of peat fire on soil flora and fauna, soil properties and environmental damage in Riau Province, Indonesia. Biodiversitas 20: 1770-1775. Land fires set by communities can result in the death of flora and fauna, damage the soil, and cause smoke disasters. In this study, we focused on the burnt community land in Riau Province, where we conducted a soil analysis through purposive sampling to highlight the effect of the fires on the environment. Our findings showed that fires caused a decrease of peat soil thickness of 10-15 cm, and resulted in 100% mortality of soil flora and fauna. We found a significant increase in the Ca and soil pH after a fire, but total microorganisms, total fungi, and soil respiration are found decreased. Our results strongly showed that the soil and environmental damage of burnt peat soil on community land exceeded the minimum criteria to be classified as "environmental damage" as defined by Indonesian Government Regulation No. 4/2001 (PP No 4/2001) for the parameters of bulk density, porosity, pH, organic C, N, total microorganisms, total fungi, and respiration.

Abstract. Saharjo BH, Hadiwijoyo E. 2019. Short Communication: Land cover changes from 2005 to 2015 in Mantangai area of Dayak Ngaju, Central Kalimantan, Indonesia. Biodiversitas 20: 2596-2602. Forest and land fires in Indonesia are well recognized, directly or indirectly, as the main contributors to deforestation and greenhouse gas emission related to the global climate change. Usually, local peoples are blamed for those fires especially when negative impact occurred. Fortunately, not all of the local peoples do the same thing as it is shown by Dayak Ngaju in Block A of ex-Mega Rice Project (Ex-MRP) Project area located in Mantangai sub-district Kapuas district, Central Kalimantan Province, Indonesia, where this research was conducted. The objective of this study was to know land the cover changes related to the use of fire for land preparation, and how the Dayak Ngaju people implement their knowledge and experience in the field. This objective was achieved by analyzing satellite images of Landsat 7 and 8 for a period of time starting from 2005 to 2015. Results of the research showed that the local people started clearing the land with fire at the end of September (dry season) or early October (the rainy season) yearly, as it could be seen from the changes of the land cover from secondary swamp forest into swamp shrub and from secondary swamp forest into fields. Meanwhile, at the protected area where peat was dominant, land cover change occurred due to land rights conflicts, and not to the use of fire for land preparation using fire by Dayak Ngaju communities, because they found that the results were not good and the planted rice would die three months after planting..

Abstract. Silviana SH, Saharjo BH, Sutikno S. 2019. Effect of wildfires on tropical peatland vegetation in Meranti Islands District, Riau Province, Indonesia. Biodiversitas 20: 3056-3062. Wildfires are one of the main causes of forest destruction, disturbing forest sustainability. Wildfires are mainly caused by human activities, such as land clearing, wood harvesting, draining, etc. Wildfires could induce the loss of vegetation. This study was aimed at assessing the effect of wildfires on both vegetation biomass and necromass on coastal peatland ecosystems in Sungaitohor Village, Tebing Tinggi Timur Sub-district, Meranti Islands District, Riau Province, Indonesia. Analysis of vegetation and both above and below the ground biomass composition were performed. The approach used a paired sample with 4 replications (n = 4 burnt, n=4 unburnt). The variables observed in every research sites was analyzed using Student-T test. Models were generated and then validated to understand the effect of fires on biomass. The results showed that there was a significant difference in the studied parameters between the unburned area and burned area (P <0.01). Wildfires affected the quantity of living plants (biomass) which was indicated by the fact that biomass is unburnt and burnt areas were in the ratio of 2.67 : 1. The quantity of dead plants (necromass) was greater in the burned plots than in the unburnt plots. All these findings suggest that high intensity of forest fires had occurred in the study sites.

Abstract. Silviana SH, Saharjo BH, Sutikno S. 2021. Distribution of carbon stocks in drainage areas on peatlands of Sungai Tohor Village, Meranti Islands District, Indonesia. Biodiversitas 22: 5106-5114. Peatland ecosystems provide a variety of environmental services and biodiversity with their ability to store and absorb carbon. The increase of land clearing followed by the construction of drainage or canal has resulted in the degradation of peatlands and is prone to fire incidences. Canal construction, whether we realize it or not, has a negative ecological impact on the in situ (local) environment, namely land degradation and subsidence, as well as a wider (global) impact in the form of loss of carbon stocks, increased GHG emissions that can trigger global warming. This study aims to identify the distribution of carbon in the area where drainage is made where the distribution of carbon stock in starting at a distance of 10 m, 50 m, 100 m, 250 m, and 350 m from the canal. The study was conducted on the community plantations including unburned areas (rubber plantations and secondary forests) and burned areas. The influence of land use and drainage development on carbon stock distribution is rarely known. The results showed a decrease in C-Stock with a decrease in drainage distance. The quantity of carbon stock in secondary forests ranged from 13.275 ton ha-1 - 24.839 ton ha-1, Burnt Area-1 ranged from 6.995 ton ha-1 - 11.59 ton ha-1, and Burnt Area 2 ranged from 4.677 ton ha-1 - 12.580 ton ha-1. In contrast, rubber plantations had higher C-stock in the initial observation distance, around 9.064 ton ha-1 - 11.805 ton ha-1, which may be due to intensive land use near the canal.
