Abstract

The rubber  agroforests  (RAF)  of Indonesia provide  a dynamic interface  between natural  processes  of forest  regeneration and  human’s management   targeting  the harvesting  of latex  with  minimum investment  of time  and financial  resources.  The composition  and species richness  of higher  plants  across an intensification gradient from forest to monocultures of tree crops have been investigated  in six land use types (viz. secondary forest, RAF, rubber monoculture, oil palm plantation, cassava field and Imperata grassland)  in Bungo,  Jambi  Province,  Indonesia.  We emphasize  comparison of four different  strata  (understory, seedling,  sapling  and tree) of vegetation  between forest and RAF,  with  specific interest  in plant  dependence  on ectomycorrhiza fungi. Species richness  and species accumulation curves for seedling  and sapling  stages were similar  between forest and RAF,  but in the tree stratum  (trees > 10 cm dbh) selective thinning by farmers was evident in a reduction  of species diversity and an increase in the proportion of trees with edible parts. Very few trees dependent on ectomycorrhiza fungi were encountered  in the RAF. However, the relative distribution of early and late successional species as evident from the wood density distribution showed no difference between RAF and forest.

Abstract

Population growth leads to water scarcity in terms of both quality and quantity. Agricultural and urban watersheds potentially produce more pollutantsthan forested area. It is considered that forested area has potential in storing and protecting water supply in such a way that water distribution and quality can be guaranteed. The objective of  the study was to determine the relationship between the percentages of forested area in a watershed with the water quality. Thestudy was conducted in 2010in GrojokanSewu Sub-watershed, Karanganyar District, Central Java. Using GIS (Geographic Information System), this sub-watershedwas divided into four sub-sub-watershedswith different percentages of forested areas. Water samples were collected in each sub-sub-watershedto find out the relationship between the forested area and the total dissolvedsolids, turbidity, sodium, nitrite, nitrate, sulfate and organic matters. The statistical analysis indicates relationships in quadratic form between sodium, nitrite, TDS, sulfate and organic matters with the percentage of  forested area (R2=0.99, R2=0.99, R2=0.98, R2=0.95 and R2=0.77, respectively). The relationships are different from those of turbidity and nitrate that have low R2 (R2=0.28 and R2=0.36) values. It implies that the forested area is capable to reduce sodium, nitrite, TDS, sulfate and organic matters, and thus water pollutants can be reduced by forest formation as it can filter water through retention of sediments and nutrients.

Abstract

Bamboo-based agroforestry is suitable for soils which are poor in nutrient. The characteristics of bamboo and the rapid closure of  its canopy improve soil cover, soil nutrient availability and soil moisture  content,  and  prevent  erosion  by reducing surface runoff. The  research was aimed at determining the factors that influenced surface runoff and the availability of soil organic matter (SOM) in the bamboo-based agroforestry in East Lombok. Research was done from March 2010 to March 2011 in Lenek Daya village, Aikmel sub-district, East Lombok district. The research plots were located on slopes of 0-15o, 30-45o, and 45-65o; with bamboo canopy closures of 0-25%, 25-50%, 50-75%, and over 75%. The research involving 12 plots, each in 4 x 12 m size. Measurements included surface runoff, bamboo canopy closure, weeds and bamboo leaves litter weight, rainfall depth and duration, dissolved sediment, and soil physical and chemical properties as well as SOM. Correlation and multiple linear regression tests were used in data analysis. The results of the regression tests showed a change in surface runoff which was influenced by changes in bamboo canopy closure, rain duration, rain intensity and soil sand fraction, each by -0.019, 0.418, 0.049 and -0.065 respectively. Rain duration was the highest influencing variable, whereas bamboo canopy closure significantly decreased surface runoff. Bamboo canopy closure had no correlation with the increase of SOM. But, the increase of SOM had correlation with the increase of  soil cation exchange capacity (CEC). The positive impact of  bamboo canopy closure  on  Regosol soil fertility in  bamboo-based  agroforestry land  was determined  by  land management intensity which could increase the availability of SOM and decrease phosphorus element loss due to leaching of nutrient.

Abstract

The purpose of this study was to formulate effective and efficient institutions of Revolving Fund Loans for Community Forest Plantation development (RFL CFP) in accordance with variation of field conditions. Benchmarking techniques were used to formulate the institution of RFL CFP. For that purpose, Independent of Direct Assistance Rural Agribusiness Development (IDA RAD) from the Ministry of Agriculture was selected as a benchmark as it was good in performance. The study was conducted in three provinces, i.e. Riau, South Kalimantan (November 2008 to April 2009) and West Java (May 2009 to February 2011). Comparative study was used to analyze the institutions based on the agency theory. The results showed that the institutional of RFL CFP have not accomodated the differences in characteristics, perceptions and capacities of the parties. As a result, the institutions have not been able to overcome the risk of moral hazard, adverse selection and high transaction costs. On the other hand, the institution of IDA RADhas a positive impact on agency relationship. High repayments by IDA RADagent and the increasing number of agents each year have proved the impact.

Abstract

Hoya multiflora is one of the valuable germplasm in Indonesia that has been utilized as ornamental and medicinal plant. This epiphytic plant faces problems in decreasing habitat. As a means for developing a habitat framework for describing the distributions and ecological relations of H.multiflora at Gunung Gede Pangrango National Park, Bogor, Indonesia, ecological study of this species was established over the ranges of altitudes and characteristic vegetation structural types (primary and secondary forest, and plantation) present in the Park. Recognizing the fact that such study requires multidisciplinar y data, this paper explores the evidences from both herbarium sheets and field observations. The result of the study showed that the population of this species was only found at the Bodogol Research Station at elevation of 700 - 900 m above sea level (a.s.l.). Thus, the facts contradict with the evidence from the herbarium sheets of the Herbarium Bogoriense which have presumed that this species has a wide variation of altitudinal range from 20 to 1500 m a.s.l. (Indonesia) or 200 - 1400 m a.s.l. ( Java). The Bodogol’s population showed the clumped type of dispersion (Morisita’s Index = 1.35), which indicated such environment that was characterized by patchy resources. Direction and speed of wind coupled with the topography are ecological factors that affect to the distribution of this parachute typed seeds of the H.multiflora.

Abstract

Following the results of the comprehensive tree improvement programs for Acacia mangium, it is necessary to estimate the real amount of genetic improvement and to develop an improved seed deployment strategy.  This study was aimed to verify realized genetic gain on stand volume productivity attained by the first-generation Seedling Seed Orchards (SSO) of A. mangium and to identify the magnitude of seed sources x site interaction as a basis for improved seed deployment. Seeds from five SSOs were tested together with seeds from seed stand in genetic gain trials which were established in South Kalimantan and Central Java. Realized gains were calculated from the percentage improvement of respective SSOs compared with seed stand at two and four years of age. Seed source x site interaction was investigated through analysis across the two sites.  Results of the study showed that trees derived from the five SSOs produced better stand volume than those from seed stand. At four years of age, stand volume of the best SSO reached around 127 m3/ha in South Kalimantan and 84 m3/ha in Central Java.  Realized genetic gain were around 66% at two years and 59% at four years in South Kalimantan, and around 136% at two years and 81% at four years in Central Java.  Seed source x site interaction was not significantly different indicating superiority of improved seed were consistent across the two sites with the average realized gain ranging from 18% to 79% and 24% to 62%  at two and four years, respectively. The best three SSOs were SSO-1 located in Pleihari-South Kalimantan, SSO-2 in Pendopo-South Sumatra and SSO-5 in Wonogiri-Central Java, all of which  originated from Papua New Guinea provenances. Improved seed from the orchards could be used at plantation sites without any significant change of the order in their superiority for stand volume productivity.

Abstract

Wood anatomy of Shorea mujongensis P.S. Ashton was investigated in order to ensure this species belongs to yellow meranti group. Such study is very important since this species is already listed in the red list of IUCN and classified as critically endangered species. The microscopic slides were prepared according to the Johansens method, while the anatomical features observed according to the IAWA  List. The results show that S. mujongensis wood exhibit brown heartwood, light brown sapwood, rough texture, straight grain sometimes interlocked and somewhat rough. The main microscopic characters are growth rings indistinct; vessel diffuse, mostly solitary, rounded to oval; simple perforation plate and alternate intervessel pits; parenchyma scanty paratracheal to thin vasicentric; axial intercellular canals in long tangential line, radial intercellular canal and vasicentric tracheids present; rays uniseriate and multiseriate, prismatic crystal in procumbent cells; fiber length 1,294 µm, diameter 26 µm and wall thickness 4µm. Macroscopic and microscopic observation of S. mujongensis wood confirms the species belongs to yellow meranti group. The assesment on fiber dimensions and derived values of the wood fibers classified the wood into class quality II. It indicates that this species is moderately favorable as raw material for pulp and paper manufacture.

Abstract

This study was conducted to provide basis information of the 25 local specific wood species indigenous from Java treated by copper bichromated boron (CCB). The full-cell process for 2 hours and 150 psi during the pressure-keeping period was employed. The IUFRO method was applied for the determination of wood treatability class. The treated and untreated wood specimens were tied together using plastic cord, arranged into a raft like assembly, and then exposed for 3, 6, and 12 months to the brackish water situated at Rambut Island’s coastal area. The Nordic Wood Preservation Council (NWPC) standard No.1.4.2.2/75 was used to determine the intensity of marine borer infestation. The results revealed that 19 out of those 25 species were classified as easy to be preser ved, four species as moderate, and the remaining two were difficult to be preser ved. Those 19 species, i.e. Tamarindus indica L., Diplodiscus sp., Ficus variegate R .Br., Ehretia acuminata R .Br., Meliocope lunu-ankenda (Gaertn) T.G. Hartley, Colona javanica B.L., Pouteria duclitanBachni., Stercularia oblongata R .Br., Ficus vasculosa Wall ex Miq., Callophyllum grandiflorum JJS., Turpinia sphaerocarpa Hassk., Neolitsea triplinervia Merr., Acer niveum Bl., Sloanea sigun Szysz., Castanopsis acuminatissima A.DC., Cinnamomum iners Reinw. Ex Blume., Litsea angulata Bl., Ficus nervosa Heyne., and Horsfieldia glabra Warb. were more permeable implying that the CCB retention and penetration were greater and deeper. Hymeneaecarboril.L., LitseaodoriferaVal., Gironniera subasqualisPlanch., and LinderapolyanthaBoerl. were moderately permeable. Castanopsis tunggurut A.DC. and Azadirachta indica Juss. were the least permeable judging that the CCB retention and penetration were lowest and shallowest. The treated wood specimens in this regard were able to prevent marine borers attack. Meanwhile, the untreated specimens were susceptible to marine borers attack, except Azadirachta indica. The attacking borers consecutively are MartesiastriataLinne that belongs to the Pholadidae family ; and Teredo bartschi Clapp., Dicyathifer manni Wright., and Bankia cieba Clench. to the Terdinidae family.

Abstract

Stigma  receptivity based on seed set and pollen  tubes growth  following controlled pollination of flowers  of different  ages was examined  in Melaleuca alternifolia. The stigma secretion during 10 days after anthesis and pollen viability under three different temperatures and five storage times were also observed. These series of research were undertaken because successful controlled pollination of M. alternifolia depends on the application of viable pollen to the receptive compatible  stigma. The objective of this research was therefore to determine the stigma receptivity and pollen viability of M. alternifolia. Results showed that the stigma receptivity began to develop  on day  one and finished  on day  seven after anthesis,  peak receptivity occurred from day three to day six. The stigma receptivity also coincides with the appearance of secretion in the stigma, occurring  from day three to day seven after anthesis. Therefore,  the time for pollination of M. alternifolia appeared to extend for  approximately 7 days after anthesis. Data for M. alternifolia showed that regardless of storage temperature, pollen  was still  viable  after 26 weeks  of storage;  results also demonstrated  that the lowest temperature  (-18oC) was the best regime for long term storage.
