The dependence on imports of feed ingredients for ration composer are increasingly expensive and availability of limited and unsustainable local feed, causing the low level of production and reproduction of local Indonesian cattle. This study aims to exploit the potential of plantation waste as an alternative feed of beef cattle, increase the nutrient value and digestibility of waste of palms and leaves and to know the optimal use of inoculums (Trichoderma sp.) through fermentation in improving the digestibility and nutritional value of the feed. The research method used was a complete randomized design (RAL) with five treatments and three replications, with 14 days fermentation. The research treatment includes: PD 0 (without Trichoderma/control), PD 1 (fermentation using Trichoderma viride 3 ml), PD 2 (fermentation using Trichoderma viride 6 ml), PD 3 (fermentation using Trichoderma harzianum 3 ml), PD 4 (fermentation using Trichoderma harzianum 6 ml).O Observation parameters observed included dry matter (DM), crude protein (CP), ash content (AC), coarse fat (CF), organic matter (OM), and total digestible nutrient (TDN). The data obtained were analyzed using variance analysis. The results showed that the best treatment was found in PD 1, had a significant effect on control in increasing total digestible nutrient (TDN) 51.62% and crude fiber decline by 39.14%, although an increase in CP (5.34%) was not equal to the treatment of the PD 4 (5.35%). While the best increase of CP content was found in the treatment of PD 4 of 3.35%. While the best CP content found in the treatment of PD 4 of 5.35%. It was concluded that the use of Trichoderma viride and Trichoderma harzianum can improve the quality of waste nutrient and palm oil leaves by fermentation and the optimal inoculums dose used to produce the best fermentation is the use of Trichoderma sp. 3 ml in 3kg of material.

<p class="Abstract">Basal plate rot is a major disease on shallot caused by <em>Fusarium oxysporum</em>. Endophytic fungi is promising to use as antagonist agent to the pathogen. Endophyte is microbes that are living in plant cells and have an asymptomatic characteristic. Nowadays, fungal endophyte is believed to produce antimicrobial substances similar with their plant host's natural product. <em>Jatropha curcas</em> is one of the plants containing secondary metabolites that have antifungal activities. The research aimed to study the ability of endophyte from <em>Jatropha curcas</em> to inhibit the growth of <em>Fusarium oxysporum</em>. The dual culture method was used in this research and the data were analyzed by SPSS software. This antagonism test was conducted by 9 isolates endophyte and each plate consisted of 3 replicates. The result revealed endophyte fungal obtaining 9 isolates with the radial growth of 4,5 cm/2 days. Endophytes of <em>Jatropha curcas</em> L. were able to inhibit the growth of <em>Fusarium oxysporum</em> C2. The percentage of inhibition of <em>Fusarium oxysporum </em>causing of root blight diseases was controlled by up 38.27 - 74.48%. The highest percentage of inhibition is gained by B4b and the lowest of it is A2b. Our observations showed that each endophyte has a consistent linear trend. B4b still leaded as the highest strength to inhibit the growth of pathogen on the monitoring of 3, 5, and 7 days. Moreover, the ability of fungi endophyte from <em>Jatropha curcas</em> as antagonist agent to <em>Fusarium oxysporum</em> needs to be further examined by the in vivo method.</p>

landing aircraft must have a negative impact on the environment. therefore, necessary to assess the role of the community using the willingness to pay towards the implementation of eco-airport Syamsudin Noor Airport in Banjarmasin. The purpose of this study is to identify the condition of the airport now to the application of the concept of eco-airport underway, estimate what the public is willing to pay for environmental improvements, analyze the factors that affect the implementation of this concept. Selection of sample is purposive sampling. The study is divided into three groups of workers, the public and passengers. Workers 23 respondents, 12 respondents community, and passengers 57 respondents. Most respondents rate Syamsudin Noor Airport Banjarmasin quite clean, quite beautiful, quite noisy, quite, quite comfortable and does not know the concept of eco-airport. A total of 53 respondents are willing to pay an average willingness to pay Rp. 11.320,75 per person per flight. Variable cleanliness and beauty affect the value of willingness to pay by 10%.
