Abstract

Fungi is natural resources that has many potencies to be developed to fill the human’s need. One of useful fungal species is Xylaria sp. as a decomposer which play an important role in the process of returning nutrients in to the soil. This reasearch aims to examine the effect of medium pH, medium movement, and sawdust of Sengon (Falcataria molucana) & Afrika wood (Maesopsis eminii) addition in medium on the growth of Xylaria sp. Each experiment used Completely Randomized Design with 3 replications. The result showed that best Xylaria sp. colony on PDA attained at pH 8; at pH 2 the fungi did not grow. Highest mycelial dry weight of Xylaria sp. in PDB medium with pH treatment was achieved at pH 6. Highest mycelial dry weight of Xylaria sp. in PDB with shaking was achieved at a speed of 100 rpm. The addition of sawdust in MEA medium did not significantly affect the growth of mycelial diameter of Xylaria sp.Key words: africa wood, medium movement, pH, sengon, Xylaria sp

Abstract

Botryodiplodia sp. is causes dieback disease of jabon (Anthocephalus cadamba (Roxb.) Miq). Dieback disease causes a decrease in the quality and economic value of jabon seedlings in the nursery. Research on control of the disease is still rare. Control of the disease is divided into three ways, namely chemical, physical, and biological. One biological control can be biological agents. Biological agents are used in this study is Trichoderma harzianum and Gliocladium sp. on in vitro test. The test results showed that T. harzianum antagonism with the direct method able to inhibit the growth of Botryodiplodia sp. with the average 52.53% and 35.99% respectively on PDA and Czapex Agar, while Gliocladium sp. able to inhibit the growth of Botryodiplodia sp. Average 46.46% and 28.51% respectively on the PDA and Czapex Agar for 7 days of observation. Results of antagonist test with indirect methods showed that the filtrate of T. harzianum and Gliocladium sp. has the ability to inhibit the growth of Botryodiplodia sp. at 13.42% and 10.25% PDB media significantly different from controls. T. harzianum and Gliocladium sp. have ability to inhibit the growth of Botryodiplodia sp. greatly.Key words : Botryodiplodia sp., Gliocladium sp., in vitro test, Trichoderma harzianum

Abstract

Mangrove forests have an important role in reducing the effects of global warming. This study aims to analyze vegetation and estimate carbon stock in mangrove stands in the Mangrove Island of Petengoran Mangrove Ecotourism Area, Gebang Village, Lampung. The forest vegetation analysis method used is the plotted path method. Paths and plots were taken systematically with tree observation plots made measuring 20 m x 20 m. Carbon estimation was carried out by non-destructive sampling method using the allometric formula for Rhizophora apiculata log BBA= -1.315 + 2.614 log D. The results showed that the mangrove island zone was dominated by Rhizophora apiculata vegetation with a density of 325 ind/Ha. The research location has a silty clay loam soil texture with a temperature range of 25°C-32°C which is very suitable for the vegetation of R. apiculata. The estimated carbon stored in the vegetation was obtained from 46% of the standing biomass of R. apiculata, which was 86,283 tons C/Ha.KEYWORDSBiomass, Carbon, Mangroves, Petengoran, Vegetation

Abstract

Abstract Community Service entitled "Empowering Forest Communities through the Application of the Sonokeling Tree Barcoding System as an Effort for Forestry Social Disaster Management in Wan Abdul Rahman Forest Park, Lampung Province" is motivated by the condition of the Tahura Wan Abdul Rahman area which is vulnerable to illegal logging, especially the Sonokeling (Dalbergia latifolia). Illegal logging is one of the social disasters of forestry and threatens the sustainability of forests and the various resources in them. This is also faced with the limited personnel of related institutions in dealing with social disasters. Therefore, the PkM team consisting of ITERA lecturers from the Forestry Engineering Study Program assisted in gathering information regarding the potential of sonokeling stands in Tahura WAR and developing a barcoding system (QR Code) that would facilitate monitoring and securing rosewood stands from the threat of illegal logging. The barcoding system application is also expected to be able to support the Tahura WAR foster tree program which will be initiated later to increase community empowerment in maintaining forest sustainability. Keywords: foster tree, WAR Forest Park, QR Code
