Abstract

Peat land in the east coast of Sumatera (Riau, Jambi, South Sumatera) and Kalimantan (South Kalimantan, Central Kalimantan and West Kalimantan) has being used for agricultural crops such as rice field, palm oil and coffee plantation. land preparation practiced is slash and burn method. Smoke haze that produce from peat fires were caused by these method. To determine the impact of such practice to atmospheric quality, a study was conducted at Pelalawan Province Riau. Four plots on peat land were prepared at sapric and hemic, each plot was 20 m x 20 m (0,04 ha). Before burning vegetation was cleared off, then the plots were circularly burned (ring fire) and greenhouse gases emitted were measured. The average of greenhouse gases emitted from sapric plot burning were 273 ppm CH[4], 10.395 ppm C0[2] and 1.223 ppm CO. Greenhouse gasses emitted from hemic plot burning were 306 ppm CH[4], 10.678 ppm C02 and 2176 ppm CO. The high CO emission from peat burning indicate there has been an incomplete burning at the fuel, due to high fuel moisture. The largest single atmospheric emission from peat burning was C0[2] and the smallest was CH[4] • The increase of greenhouse gases emission will contribute to global climate change, especially the global temperature increase through greenhouse effect of the gases.

Abstract

Land changes become oil palm plantations accused of contributing greenhouse gas emissions (GHG) included in the mineral soil, therefore it is very important to gather information in mineral soil CO2 emissions to support mitigation and adaption to climate change. This purpose of this research determine the CO2 emissions in the oil palm plantations planted crops in the vegetative stage and generative phase, as well as to determine the ratio of CO2 emissions in the oil palm plantations planted crops in the vegetative stage and generative phase. This research was conducted in November 2015 to February 2016 in Subdistrict of Tambang, District of Kampar, Province Riau. The method used in this research was Random Block Design with four treatments and replications. The treatments were oil palm-bera, oil palm-corn, oil palm-soy bean, oil palm-intercropping corn soy bean. The research showed that CO2 emissions in the oil palm plantation intercropped with crops (corn and soybeans) in the vegetative phase showed no significantly different. Comparison large of CO2 emissions indicated oil palm-corn vegetative phase.

Abstract

Peat land conversion into oil palm plantations leads was increased emissions of carbon dioxide (CO2). Plants on peat land and environmental conditions believed to be factors in the emission of carbon dioxide (CO2). The porpuse of this research was determined the emissions of carbon dioxide (CO2) in oil palm plantations are intercropped with cropping crop on peat land and the influence of environmental factors on the emission of carbon dioxide (CO2). This research was conducted in September 2015 until April 2016 in Rimbo Panjang village, Subdiscrict Tambang, District of Kampar, Province of Riau. Cropping crop used were corn and soybeans. The method used in this study was a Random Block Design with four treatments and four replications. The treatments were palm - berau, palm oil - corn, palm oil - soybean, palm oil – intercropping (soybean – maize). Parameters measured were carbon dioxide (CO2), soil temperature, air temperature, the temperature of the lid, the depth of the water table and soil pH. The results showed that carbon dioxide emissions (CO2) in oil palm plantations are intercropped with cropping crop (corn and soybeans) were not significantly different. The influence of air temperature, soil temperature, the temperature of the lid, and the depth of the ground water level were inversely and  insignificant to the emission of carbon dioxide (CO2). As for getting nearly neutral pH, the emission of carbon dioxide (CO2) is increasing, but insignificant.

Abstract

Rice paddy (Oryza sativa L.) is important and main food plant in Indonesia. The problems field cultivation rice paddy in wetland is declining ground water availabity and uncertain climate change. The research was carried out with the aim to get the rice paddy local from the Kuok district, regency Kampar that is resistant to the condition of the grasp of drought in the phase of germination. The research was conducted in November-December 2016 at Pathology, Enthomology and Microbiology laboratorium and experimental field State Islamic University of Sultan Syarif Kasim Riau. Experiments were prepared using a completely randomized design factorial the first factor were 10 genotypes rice paddy local and the second factor was solution PEG concentration 6000 0% and 20%. Parameters observed that the germination (%), vigor index, crown length increment (cm), root length of wax coating (cm), and the number of penetrating root of wax coating. Based on result analysis of tolerance index recapitulation from five variables observation parameters there are nine genotypes that are tolerant to drought stress and one genotype susciptible to drought stress
