Abstract

Peatlands become one of the potential resources that could be developed as an area of rice farming to improve national food security. Agricultural cultivation in peatlands, if not managed well, will contribute to environmental destruction and land degradation, which will ultimately affect land productivity. As a first step in preparing the development of rice farming, research on the application of technology has conducted. This research included water management, which consists of:  without water management or control (A0), macak-macak water management (A1) and intermittent water management (A2). Moreover, research on pesticide application was also conducted which consist of: without pesticide application or control (P0), Paraquat herbicide application at the time of tillage (P1), Fenobucarb insecticide applications every week (P2), Fenobucarb insecticide applications every two weeks (P3), Difenoconazole fungicide applications every week (P4), Difenoconazole fungicide applications every two week (P5).  This study aims to determine the level of sustainability of rice farming in peatlands, and the dominant factors that influence by considering economic, social and environmental through a Multi Dimensional Scaling (MDS) approach. The analysis shows a quite sustainable level, with score for each dimension is 53.13 for the economic dimension, 69.49 for the ecological dimension and 61.79 for the social dimension. The dominant factors to be considered for the sustainability of rice farming in peatlands are changes in the level of decomposition of organic matter, farming purpose and outreach intensity.

Abstract

Rudrasagar lake, a Ramsar site in India offers a variety of ecosystem services. The contribution of Rudrasagar lake to the society has not been estimated so far. The preliminary study aims to provide an economic valuation of the provisional and cultural services of the Rudrasagar lake. Official records of revenue collected by the Tourism Department of Tripura and a socio- economic survey was the source of information used in the economic valuation of the lake. The main provisional services provided by the lake are food (aquatic plants and fishes), fuel wood and timber whereas, the cultural services provided were boat raiding and tourism due to its historical importance. The provisioning and cultural services provided by the Rudrasagar lake are 40810 US$ and 33929.33 US$ per year respectively during the period of 2010-2015. The main threats to the wetland identified are increasing silt loads due to deforestation, expansion of agricultural land and land conversion due to population pressure. To alleviate the anthropogenic stress on the lake, better monitoring, planning and management are essential. By proper conservation and management it will be possible to enjoy the provisional and cultural services of the lake in a sustainable way.

Abstract

Water lettuce (Pistia stratiotes) is one of the important aquatic weeds because it can cause many problems for humans and the environment. In addition, the declining quality and quantity of water is also due to the invasion of water lettuce weeds covering the surface of waters, which can lead to the increasing transpiration and destruction of plankton making the balance of the ecosystem disrupted. This study was conducted in an attempt to control P. Stratiotes by utilizing the biological control agent Spodoptera pectinicornis with mass production and its releasing applications in South Kalimantan’s waters. The study was started by taking and collecting S. pectinicornis from several places/fields. The moths were then placed in trays of water and put in a gauze cage of 75 cm x 75 cm x 75 cm in order to keep the air circulation. They were nourished in the laboratory to produce groups of eggs. The groups of eggs were then transferred to rearing ponds. When a fair number of agents were obtained, the treatment of liquid fertilizer AB Mix was carried out. The results showed that the fertilization treatment to water lettuce weeds as the food for the biological control agent S. pectinicornis did not differ from the condition when there was no fertilization treatment either on the feeding ability, weight of larvae and pupae or fitness of imago. However, its destructive ability is high that it has a big potential as a biological control of water lettuce.

Abstract

Several experiments have been carried out to elucidate the reduction in greenhouse gas emissions as effect of replacement of chemical fertilizer by biofertilizers on alluvial soils in Indonesia.  Biofertilizers “Biotara” and “Biosure” were applied along with NPK fertilizer on alluvial soil cultivated with rice.  Emissions of nitrous oxide (N2O), methane (CH4) and carbon dioxide (CO2) were monitored in biweekly basis up to the maximum vegetative growth of the rice plant. Oil palm empty fruit bunch (OP EFB) as well as grasses were composted with Bacillus brevis and Bacillus megaterium as activator. The composts were incorporated into alluvial soils cultivated to oil palm and the emissions of N2O, CH4 and CO2 were monitored in biweekly basis. The results showed that biofertilizer “Biotara” or “Biosure” combined with NPK fertilizer (¾ recommendation dose) could increase paddy growth with no significant effect on N2O, CH4 and CO2 emissions.  The emissions of N2O,  CH4 and CO2 exhibited seasonal changes as affected by inclusion of either OP EFB and weed compost along with NPK fertilizer.  Global warming potentials of each treatment for NPK, OP EFB compost and weed compost were 5.6, -5.2 and -4.9 ton CO2equ m-2 year-1, respectively. It could be concluded that the replacements of synthetic fertilizer with biofertilizer or compost did not have negative impact on the environment which could be promoted.

Abstract

ABSTRACTTalas banana (Musa paradisiaca var. sapientum L.) has a high economic value. However, because of slowly breeding, a quick way of propagation: i.e. in vitro is required.Peatlands inSouth Kalimantan are quite large and has potential to be used for planting area of Talas banana. The acclimatization of seedlings planted on the peatsrequires more fertilizers, considering the low nutrient content of the peats. This study aims to determine the chicken manure and nitrogen-phosphor-potassium (NPK) fertilizer on the growth of Talasbanana acclimatized in peatlands. This study applied a randomized block design (RBD) factorial: (1) the amount of chicken manure (K), namely: k1 = 5 t ha-1; k2 = 10 t ha-1; k3 = 15 t ha-1; k4 = 20 t ha-1, and (2) the amount of NPK fertilizers (P), namely: p1 = 200 kg ha-1; p2 = 250 kg ha-1; p3 = 300 kg ha-1. Therefore, 12 treatments. DITAMBAHKAN TERDAPAT 12 PERLAKUAN. All treatments have 3 replicates. The results of the experiment showed that there was no interaction between doses of chicken manure with NPK. The amount of chicken manure 5 t ha-1 resulted in the highest increment of plant height observed at 2nd, 4th, 6th, 8th, 10th and 12thweek after planting, increment of stem diameter, addition of leaf number, width and length of leaves.The results of experiment also revealed that the best increment of plant height observed at 8th week after planting and stem diameter observed at 4th week after planting was obtained by 250 kg ha-1of NPK fertilizer application.
