Potential and Superior Commodities of Peat Hydrology Area (PHA) of Ogan Komering Ilir Regency South Sumatra (Case Study : PHA Saleh River – Sugihan River)

oai:ojs.pps.unsri.ac.id:article/217Non-timber forest products (NTFPs) are a great potential in the forest, one of which is in the Saleh-Sugihan River Peat Hydrology Area (PHA). More optimal utilization of NTFPs is obtained with more diverse types of NTFPs, so it is important to know the diversity and potential of commodities in peatland areas for further development based on NTFPs. The research had been conducted from May to July 2018 in the PHA area of the Saleh-Sugihan Rivers, choosing Pangkalan Lampam District, Ogan Komering Ilir Regency, South Sumatra. Research sites include the villages of Air Rumbai, Deling, Lirik, Pangkalan Lampam, Rambai and Sukaraja. The research method is used by sampling, observation and interview methods. Determination of selected commodities uses analysis of Non-Timber Forest Products / NTFPs (Regulation of the Minister of Forestry of the Republic of Indonesia, 2009). Based on the results of the research that has been carried out, it is concluded that the leading commodity from the Peat Hydrology Area is swallow, paddy and fish, while the main commodity in Pangkalan Lampam sub-district is buffalo and purun. Leading commodity types of swallow, paddy, fish become NTFPs which are prioritized to be developed at the PHA River Saleh-Sugihan location, so that their development will be more focused and directed, in order to improve the regional economy

Normalized Alignment of Dependency Trees for Detecting Textual Entailment

In this paper, we investigate the usefulness of normalized alignment of dependency trees for entailment prediction. Overall, our approach yields an accuracy of 60% on the RTE2 test set, which is a significant improvement over the baseline. Results vary substantially across the different subsets, with a peak performance on the summarization data. We conclude that normalized alignment is useful for detecting textual entailments, but a robust approach will probably need to include additional sources of information

Optimum Population Size of Indigenous P-solubilizing Bacteria to Correct P Availability in Acid Soils

Indonesian acid soils were used to determine an optimum population size of indigenous P-solubilizing bacteria (PSB) for solubilizating fixed P. The experiment consisted of two sub-experiments. Sub-experiment I was to isolate the indigenous PSB from Ultisols, Fresh-water lowland Inceptisols, and tidal-swamp Inceptisols. Subexpriment II was to study the capacity of the isolated PSB to correct P availability in acid soils by inoculating the isolated PSB into the tested soils at 0, 105, 1010, and 1015 cells. The population of the indigenous PSB in the tested soils increased as a result of the inoculation. Both Al-P and Fe-P content in the three tested soils decreased as compared with the initial content. The increases of available P were significantly correlated with the decreases both in Al-P (r2 = 0.68 for the Ultisols; r2 = 0.51 for the fresh-water Inceptisols; and r2 = 0.35 for the tidal-swamp Inceptisols) and in Fe-P (r2 = 0.91 for the Ultisols; r2 = 0.45 for the fresh-water lowland Inceptisols; and r2 = 0.78 for the tidal-swamp Inceptisols). The increases of available P were significantly correlated with the increases of thepopulation of the PSB (r2 = 0.60 for the Ultisols; r2 = 0.55 for the fresh-water lowland Inceptisols; and r2 = 0.69 for the tidal-swamp Inceptisols). The available P in the three tested soils sharply increased if the population size of the PSB was about 1 × 109 cfu g-1 of soil

Mott transition in Cr-doped V2O3 studied by ultrafast reflectivity: electron correlation effects on the transient response

The ultrafast response of the prototype Mott-Hubbard system (V1-xCrx)2O3 was systematically studied with fs pump-probe reflectivity, allowing us to clearly identify the effects of the metal-insulator transition on the transient response. The isostructural nature of the phase transition in this material made it possible to follow across the phase diagram the behaviour of the detected coherent acoustic wave, whose average value and lifetime depend on the thermodynamic phase and on the correlated electron density of states. It is also shown how coherent lattice oscillations can play an important role in some changes affecting the ultrafast electronic peak relaxation at the phase transition, changes which should not be mistakenly attributed to genuine electronic effects. These results clearly show that a thorough understanding of the ultrafast response of the material over several tenths of ps is necessary to correctly interpret its sub-ps excitation and relaxation regime, and appear to be of general interest also for other strongly correlated materials.Comment: 6 pages, 3 figures.

Special Autonomy Papua: Compliance Against Applicable Rules/Guidelines (Case Study in Jayapura City)

The main purpose of this study is to identify and analyze the implementation of activities financed by the Special Autonomy Fund whether it is in accordance with existing rules/guidelines, whether it is seen from the routine activities, the funds used in each activity, the leverage of the implementation of activity towards the achievement the vision and mission of the regional head, the involvement of the Papuans in the activities, and the influence of the implementation of the activities towards solving the problems of the Local people. Methods used include: Quantitative descriptive statistics in the form of concentration measures, and crosstab analysis. Based on the results of this study it can be concluded that: 1) During the period of 2008-2014 the implementation of programs/activities classified routinely carried out all almost been implemented with reference to the rules / guidelines of the implementation of Special Autonomy in Papua Province; 2) Development Programs /Activities implemented through the use of Special Autonomy funds, indicating the amount of activities that use substantial amount of funds and the implementation is in accordance with the rules/guidelines of the implementation of Special Autonomy in Papua Province; 3) Implementation of development activities using Special Autonomy funds in Jayapura City has been able to play a role in improving the achievement of vision and mission of regional head, whose implementation has been in accordance with existing rules/guidelines; 4) The results of this study indicate that many programs/activities involving the implementation of many Orang Asli Papua, whose implementation has been in accordance with existing rules/guidelines; 5) Implementation of Special Autonomy policy in Papua Province is expected to solve the problems faced by Orang Asli Papua.

P Use Efficiency by Corn (Zea Mays L.) in Ultisol Due to Application of Coal Fly Ash-chicken Manure Mixture

Low P availability is the main constraint for crops on acidic soil such as an Ultisols due to high soil P sorption. The objective of current research was to determine the effect of coal fly ash-chicken manure mixture application on P use efficiency by corn (Zea mays L.) in Ultisols. The research were arranged according to Factorial Completely Randomized Design with three replicates. The treatments tested were the rates of FA-CM mixture (w/w of 1:1) that consisted of 0, 15, 30, 45 and 60 tons ha-1, and P fertilizer rates that consisted of 0, 0.5, 1.0, 1.5 and 2.0 times of P requirement to achieve of 0.2 μg P mL-1 in soil solution (equivalence to 0, 87, 174, 261 and 348 kg P2O5 ha-1). Results of current research showed that P use efficiency by corn on Ultisols had been increased through the addition of FA-CM in combination with P fertilization at the rate of 87 kg P2O5 ha-1. The optimum rate of FA-CM in combination with P fertilizer at the rate of 87 kg P2O5 ha-1 is 28.60 tons ha-1, with P uptake efficiency of 42.41 % and agronomic P efficiency of 82.53 mg shoot dry weight/mg P from fertilizer
