Mycorrhizal symbiosis is the result of mutualistic interactions between plants and fungi. Melinjo (Gnetum gnemon) naturally associate with ectomycorrhizal Scleroderma sinnamariense and Scleroderma sp. fungi. Artificial inoculation can be applied to young seedlings (1-2 months old), before the roots contain woody material. The purpose of this study was to apply the root pruning techniques to improve gnetum mycorrhizal seedlings production. The study was conducted in a greenhouse using 7 months old seedlings. The treatments consisted of 3 root pruning levels (0, 30, and 50%) and ectomycorrhizal fungi inoculum (control, mycorrhizal seedlings, and soil inoculum). Observations were carried out for 4 months to the seedling growth and root colonization by ectomycorrhizal fungi. Height, diameter, and biomass of melinjo seedlings in all treatments were not significantly different. Thus, root pruning activities do not affect the growth of seedlings. Artificial inoculation produce mycorrhizal seedlings, whereas controls were uninfected. Root pruning increased number of root branching. Root pruning at level 50% increased mycorrhizal seedlings production, but the percentage of root colonization was not significantly difefernt at all pruning levels.

Root pruning technique may improve new lateral growth. The purposes of this research are to analyse the combined effect of root pruning and inoculum ectomycorrizal types on the growth of gnetum seedling (Gnetum gnemon). This research using split plot design. The source of ectomycorrizhal inoculum as main plot consist of 3 types: control, infected seedling of ectomycorrhizal, and soil inoculum. The root pruning level as sub plot also consist of 3 types: 0, 30, and 50%. Observation is conducted on month 5th and 6th after treatment. The result of this research indicates that root pruning technique on 7 month seedling able to enhance melinjo seedling’s growth and increase ectomycorrhizal colonization (Scleroderma spp.) after 6 months observation. The source of inoculum was able to enhance ectomyrorrhizal colonization but had no significant to gnetum seedling’s growth on month 6th after treatment. Interaction between root pruning 30% and fungal inoculation with soil inoculum source can improve gnetum seedling growth.

Aloe (Aloe vera) planted in West Borneo peat soil is well known as having the best product quality in Indonesia. Soft rot disease is one of the constraints of Aloe cultivation on peat soil. Many methods have no significant result for controlling this disease. This research objectives are to obtain Plant Growth Promoting Fungi (PGPF) for controlling Aloe bacterial soft rot in peat soil. The research was conducted in Clinical Laboratory of Plant Pathology and glass house of Faculty of Agriculture, Gadjah Mada University, Yogyakarta from October 2008 to September 2009. The methods included fungal isolation from peat land, hypovirulent and PGPF ability test, and biological control test in the glass house. Among 42 peat soil fungi tested, 28 isolates were hypovirulent and only 2 isolates i.e. SNTH001 (Penicillium sp.) and SNTH003 (Aspergillus sp.) showed the PGPF ability. Glass house trial showed that single application of SNTH001 and SNTH003 isolates were able to increase the growth of Aloe. In the biological control of Aloe soft rot disease test showed that the lowest intensity (25%) might be obtained by using SNTH001 isolate.

Aloe (Aloe vera L. Webb) planted in West Borneo peat land is well known to have the best product quality in Indonesia. Bacterial soft rot is one of the constraints on aloe cultivation on peat land. Many methods have not given significant result for controlling this disease. The research objectives were to study the application of PGPF and its combination with Pseudomonas putida Pf-20 for controlling aloe bacterial soft rot on peat land. In vitro test showed that two isolates of PGPF tested had different respons when combining with P. putida Pf-20. The bacterial P. putida Pf-20 inhibit the growth of PGPF SNTH003 (Aspergillus sp.) as 20.14% on King’s B and 7.48% on PDA, whereas SNTH001 (Penicillium sp.) as 62.4% on King’s B dan 34.39% on PDA. Glass house trial showed that root dipping in P. putida Pf-20 suspension could not promote the growth of aloe, but could reduce the disease intensity. The single application of SNTH001 and SNTH003 isolates were able to increase the growth of aloe compare with its combination each of PGPF isolates with P. putida Pf-20. Single application of SNTH003, SNTH001 and P. putida Pf-20 was able to reduce the disease intensity of bacterial soft rot, but the capability decreased when each of PGPF combined with P. putida Pf-20. However combination between SNTH003 and P. putida Pf-20 increased that disease intensity. The lowest disease intensty (25%) obtained by using SNTH001 isolate.

Fusarium wilt disease is one of disease that considerable losses to the tomato plant. This disease can cause sudden death, this is due to damage to the base of the stem or cancer. Plants infected adults are able to survive and shape but the result is very little fruit and small fruit. Besides caused by pathogens, constraints cultivation in peatsoil is a peat substrate forming the lignin and cellulose are normally difficult to decompose. This study aims to find the best fungi as biological control agents against F. oxysporum and the ability to survive in acidic conditions and was able to decipher the compound lignin and cellulose. The research was conducted at the Laboratory of Plant Diseases Faculty of Agriculture, University of Tanjungpura Pontianak, January to June 2012. Implementation of the study include the isolation of fungi from peat soils, test antagonism towards the development of F. oxysporum, hipovirulensi test, capabilities and outlines the lignin and cellulose asidofilik test. Results isolation from peat obtained 7 isolates of fungi, that is Aspegillus brevipes, A. niger, Penicillium corylophillum, P. janthillenum, Rhizopus sp, Trichoderma harzianum and T. koningii. The test results antagonistic to F. oxysporum isolates obtained 2 are able to act as antagonists and suppressed the development of F. oxysporum. Both of these isolates were T. harzianum and T. koningii. Besides being able to act as antagonists, both isolates are able to decompose lignin into simpler compounds. In describing cellulose, A. niger has a greater ability than other isolates. Almost all isolates were classified into asidofilik fungus, only A. brevipes were not included asidofilik because diameter growth at pH 3 did not reach 75% compared to pH 6. Keywords: Antagonistic fungi, acidofilic, fusarium wilt.

Oil palm supply chain gaps in the Ketungau landscape of Sintang district, West Kalimantan province. The development of oil palm plantations in Sintang Regency has been rapid in the last decade. Sintang Regency has declared to implement sustainable oil palm plantations while still considering environmental sustainability aspects. Management of the oil palm trading system to be effective and efficient is the main indicator of sustainable oil palm plantations. Gap analysis in the trading system is an important effort as a basis for making various policies. The Gap Analysis of Oil Palm Supply Chain in the Ketungau Landscape, Sintang Regency, West Kalimantan Province is aimed to identify the gaps that occur between levels of oil palm trading actors in the Ketungau Landscape, Sintang Regency. The analysis is carried out using a comparison method between the current reality and the perspectives expected by the stakeholders. The results of the analysis show that in the palm oil supply chain in the Ketungau Landscape, gaps still occur at every level of the supply chain. The gap between independent oil palm smallholders and the government is the lack of assistance programs and capacity building for smallholders and improving the quality of infrastructure. The gap between the government and companies is that the government's supervision of palm oil business actors is still not maximal. The gap between independent smallholders and companies is that there is still no understanding between the two parties, especially regarding the quality criteria for FFB. The results of this study indicate that independent oil palm farmers in the Ketungau Landscape still require policy intervention from the government and oil palm companies.
