ABSTRACT

14 hectare landfill expansion in productive palm plantations pose a threat to the environment, with the first construction area of 4 hectares entirely environmental problems have not been optimal. The research objective to analyze the characteristics, the concentration of leachate in the landfill, as well as forecast the distribution of impacts based on the ebb and flow velocity Results of research on the quality of leachate is more than the limit specified under Regulation 82 of 2013. Biota water and pressure changes caused leachate concentrations relatively poor. Acus Synedra plankton distribution groups and Nitzchia palaea commonly found when tides dry,While Nitzchia palaea and Nitzchia curvula in pairs rainy. The discovery of organisms oligosaprobic and α -mesosaprobic shows the leachate polluted condition of mild to severe. Distribution deployment with the material impact of sediment and plankton drifting tide reaches 103.680 meters dry, wet tide 136.020 meters, 35.640 meters dry ebb, ebb rainy 74.520 meters at point 2 pairs of dry 1.Titik 64800 meter, plug the rainy 132.840 meters, 32.400 meters drought recede , receding rainy 38.880 meters.Need manufacture WWTP, and continuous monitoring of the quality of leachate.

Keywords: leachate, saprobic, distribution, ups and downs.

ABSTRACT

Increased productivity of rice through proper cultivation techniques such as the application of SRI method is proven to increase rice production. If there is no yield losses due to pests and diseases that high productivity can be maintained so that food security will be realized. Control of potential techniques developed is to use microorganisms ryzobacteria indigenus P. fluorescent, B. thuringiensis, and S. marcescens which is better known as biocontrol agents for control of pests and also has the potential to control seed borne diseases. Ryzobacteria is a bacteria that lives in the soil and are semi anaerobic, allowing these bacteria to live and breed in rice paddies with SRI method of cultivation. Research germination test done Payakumbuh Politani biology laboratory from February to July 2015. Tests conducted on seed germination infected with the pathogen H. oryzae then treated with ryzobacteria. Once it is planted in the home screen and the observed intensity of the brown spot disease. Seed treatment with ryzobacteria on rice seeds infected with brown spot disease caused by the fungus H. oryzae can increase the percentage of germination when compared without giving ryzobacteria and significantly different according DNMRT test at 5% level, there is no interaction between giving ryzobacteria and infection ryzobacteria seed against the percentage of seed germination . Seed treatment with ryzobacteria on rice seeds infected with brown spot disease caused by the fungus H. oryzae can reduce the intensity of the brown spot disease when compared without giving ryzobacteria and significantly different according DNMRT test at 5% level, there is no interaction between giving ryzobacteria and infection ryzobacteria seed the intensity of brown spot disease.

Keywords : S. marcecens, P. fluorescent, B. thuringiensis. H. oryzae, SRI method of paddy.

ABSTRACT

Milk industry faced several problems. In the downstream, the problems were lack of feeder cattle, low of productivity, the feed price was high, small-scale industry and un-skilled labour. In the middle-process, the problems were recording system was low, traditional technology, grazing area was limited, lack of working capital and managerial problem. Further, the problem in the upstream were price of feeder cattle was fluctuated and price of milk was low. Because of very complicated problems that mention above, the progress of milk industry is very slow and they only fulfilled 27% of national demand. The goals of this research were 1) To understand the characteristic of dairy cow industry in East Java, 2) to identify and map the main actors involved in the core processes of milk commodity chain in East Java, 3) to observe the principal function of the actors as well as the interaction among the actor. and 4) To analyse the strategy for strengthening dairy cow commodity chain. The research was conducted in Pasuruan and Probolinggo Residence. The number of respondent was 81 persons that consist of input supplier, farmer, trader and processor. The analytical tools were descriptive, actor network analysis, and commodity chain analysis.The results of the research were: 1) During 2006-2013, average dairy cow population in East Java increased 10% per year, 2) The core processes in dairy farming system are input provision, raising, milking, transportation and marketing, 3) the bargaining position  of input supplier and farmer were less than the trader and processor. The recommendations were: 1) it was needed to improve the bargaining position of input supplier and farmer through revitalization of the commodity chain in milk industry, 2) the government should force the farmer institution through improving of the farmer cooperatives.

Keywords: dairy, commodity chain, core processes, value-added

ABSTRACT

One of the efforts to reduce the negative impact of leachate waste in the environment uses adaptive plants with waste in constructed wetlands (CWs), because the method does not require high operating costs and environmentally friendly.The purpose of this study is to examine the influence of the thickness of sand media and the density of Typha angustifolia L against the COD content of waste leachate pollutants removal efficiency in CWs. This research method uses a split plot design at laboratory scale. A statistical test uses linear additive of variance analysis for a randomized group with two factors and one dependent variable. The results of the study of the average influent COD content at the level of between 495.5 mg/L to 598.56 mg/L after experiencing sequential time (7, 9, 11 and 13) days in CWs decrease to 21.83 mg/L to 68.74 mg/L. There is not a significantly (p = 0.158> 0.05) influence the thickness of sand media to the COD removal. The COD removal efficiency is significantly (p = 0.00 <0.05) influenced by the density of Typha angustifolia L plant.  The highest removal efficiency is selected on density 36 plants/m2, occurring in the thickness of sand media of 55 cm with the removal at the level of between 88.99 % to 95.96 %.

Keywords: constructed wetlands, leachate, COD, sand media, T.angustifolia L.
