Abstract

Mutation is a process of change in genetic structure of particular organisme. Genetic changes due to mutation can produce new characteristic and increase genetic diversity, which will be utilized for improvement program. Several artificial mutation programs have proved to produce new superior individual. One common artificial mutation used is gamma radiation. This study aimed to characterize 9 years old gamma irradiated sengon trees, with doses 0, 5, 10, and 15 krad based on its morphological characters, wood density, resistant to diseases. The observed parameters were tree diameter, height, volume, clear bole height, stem straightness, permanent branch, number of branches, canopy length, wood density and resistance to gall rust disease. Average values of all parameters of mutant lines does not differ significantly from control trees, however some individuals have better morphological characters than others. Mutant lines with 5 krad dose have close association with permanent branch and stem straightness, 15 krad dose with volume, diameter, height and crown length, while 10 krad with number of branches. Average wood density of mutant lines did not differ significantly from control either, with highest value belonged to 10 krad dose. Selected superior tree candidates were individuals with number 5.07, K1, 15.27, and 15 NN.Key word: breeding, characterization, mutation, sengon.

Abstract

The area of mangrove forests in Indonesia is currently only spanning as much as 3.4 milion acres, so there is a need for the participation of the government and community to maintain its sustainability. South Halmahera is the district with the largest mangrove area in the North Maluku Province. One of the mangrove areas in the District of South Halmahera is located at Sayoang Village, East Bacan Subdistrict Up until its eleventh founding anniversary, this district have never conducted an inventorizing of its mangroves, both ecological and social studies in the field of public. This study aims to analyze the compotition of mangrove species in Sayoang Village, East Bacan Subdistrict, South Halmahera, and identify the knowledge of surrounding communities of mangrove areas as protected areas. Data were retrieved using sampling method with applications terraced paths, and analyzed by calculating its important value index (INP) and its index value diversity (IVD). The public social data were taken using in-depth interviews and questionnaires. Results obtained from this study show that the mangrove forest in Sayoang Village, East Bacan District, Halmahera, consists of major mangrove species with as many as eleven species belonging to families Rhizophoraceae, Sonneratiaceae, Avicenniaceae, Meliaceae and Myrtaceae, and as many as three species of minor mangrove belonging to families of Loranthaceae, Acanthaceae, and Pteridaceae. The mangrove's species diversity and richness is and low, but it has high evenness. The results showed that 60% of total respondents know the benefit of mangrove as fish habitat, while for mangrove area as conserving areas, 50% of total respondent don't know the status of the area. The cutting problems happened in mangrove areas, 90% of total respondent know the activity and 85% of total respondent think that the logging activities in mangrove area is still allowed. The management activity of mangrove area in Sayoang village hasn't been conducted, either by the community or by local Dinas Kehutanan, and 53% of total respondent still wishing the mangrove can give more benefit economically.Key words: Mangrove forest, mangrove protected areas, community knowledge

Abstract

Logging activity is one of the factors which changes the structure of forest stand. The objective of this study was to determine the species composition and development of forest stand structure in the IUPHHK-HA area of PT. Barito Putera, Central Kalimantan, especially on the logged over area (LOA) of year 2002, 2007, 2012, and also on the pre-logged area of year 2014 as a comparison (primary forest). Based on observations which have been made, species Shorea leprosula were dominant with different rates of growth in each observation area. Growth development of the stand on logged over area can be said to be normal, because it is in the process toward a normal forest conditions. Potency of the stand before felling in 2014 was 103 trees/ha for the nucleus trees, and 49 trees/ha with volume of 317.25 m3/ha of mature timber (ready to be harvested). On LOA of year 2012, the number of core trees was 77 trees/ha, and 51 trees/ha for mature timber (ready to harvested) with a volume of 584.84 m3/ha. LOA in 2007 exhibited the nucleus trees as many as 93 trees/ha and 53 trees/ha of mature timber (ready to be harvested) with a volume of 427.95 m3/ha. LOA in 2002 exhibited nucleus trees as many as 75 trees/ha and 59 trees/ha of mature timber (ready to harvested) with a volume of 442.41 m3/ha. The differences of growth development in the observation area were probably caused by illegal logging activities that occur in the forest area, and the damage of residual stand (including nucleus trees) as a result of logging and log transportation activities. Logged over forest conditions can be said to be in balance because there were more than 25 nucleus trees/ha remaining, appropriate to the Selective Cutting and Line Planting (TPTJ) regulations, which indicates that the logged over forest can be utilized in subsequent cutting rotation.Key words: composition, Dipterocarp forest, logged-over area, core tree, stand structure.

Abstract

One of the most important pest that attacks sengon stands is boktor (Xystrocera festiva). Boktor attacks tree stem and causing high damage in term of biological, physiological and economical side. The aim of this study was to analyze damage percentage and damage level on sengon stand in terms of age, diameter and height. The result shows that boktor is starting to attack when the sengon stands are 3 years old with damage percentage and damage level were 20.26 % and 13.32%, respectively. It increased along with the increasing of age, diameter, and height. The highest percentage of damage and level of damage found in 5 years old of sengon stand i.e. 53.71% and 38.07%, respectively. The enhancement of percentage and level of damage caused by the abundant source of food, insect behavior and pest management. Boktor mostly attacks sengon stands in the range of 15.5-18.5 cm in diameter (frequency = 30 trees/ha) and 18.5-21.5 m (frequency = 40 trees/ha) in total height.Key words: boktor, damage percentage, damage level, sengon, tree age

Abstract

Mutation breeding is a powerful tool to provide novel trait in plants. However their applications in forestry are still limited. Acacia mangium is a major commercial plantation species in Indonesia and other Southeast Asia countries. Therefore, we were trying to improve its productivity. In 2008, 1200 A. mangium seeds had been irradiated by gamma ray 137Cs. There were 98 trees of M1 generations of 7 years old plantations that survive. Most of them are sterile with high clear bole and natural pruning, small branch with good growth angle,and almost straight cylindrical stem form. Based on growth performance, there were at least 29 M1 superior trees. During the observations, unexpected diversity in the bark colours with high and positive correlation to growth performance were discovered. Using microsatellite markers, the use of irradiations techniques provide surplus of heterozygosity with high value of Shannon’s Information Index. Dendrogram showed that almost all of M1 generation formed separate cluster from M0 generation with 0.71 genetic distance .Key words: mutation breeding, Acacia mangium, microsatellite

Abstract

Leda (Eucalyptus deglupta) is one of fast growing species that prospecting for revegetation in post mined area. Leda is able to grow in poorly soil nutrient. The aim of this research is to analyze the effectiveness of AMF and P fertilizer on growth and P uptake of leda seedling. This research was conducted in split plot in Completely Randomize Design (CRD). The application AMF as a main plot consisted of 5 levels, namely M0 (control), M1(AMF from rubber plantation), M2 (AMF from primary forest), M3 (AMF from oil palm plantation), and M4 (AMF from natural rubber). The rock phosphate as subplot, consisted of three levels, such as 0 g P (P0), 2 g P (P1), and 5 g P (P2). The result showed that interaction between AMF from rubber plantation and 2 g of rock phosphate significantly gave the best effect for height and diameter of Leda while interaction between AMF-primary forest (M2) and P1 (2 g of rock phosphate) reach the best of the total dry weight. Both AMF from primary forest and oil palm plantation that combined with 2 g of rock phosphate give the best effect but was not significantly different for P uptake and P uptake efficiency.Key words: amf, growth, miychorrhiza, leda, p uptake, p efficiency

Abstract

Invasion of Botryodiplodia theobromae as a dieback fungus on jabon merah (Anthocephalus macrophyllus) seedlings is a crucial issues. This pathogenic fungus needs to be controlled precisely. Phytochemical compounds of plant material is one alternative fungicides. Crude extracts of picung (Pangium edule) leaf in water and methanol solvent known to have antifungal potential. However, its activity against B. theobromae need to be revealed. In vitro assay aimed to measuring antifungal activity of water and methanol extracts of picung leaf on controlling growth of B. theobromae pathogenic fungus. Hot water extraction and maceration in methanol was conducted to obtain crude extract materials. In-vitro antifungal assay of water and methanol extracts of picung leaf was conducted by food poisoning method on Potato Dextrose Agar media. The results showed that water and methanol extracts of pangi leaf be able to suppress the growth of B. theobromae on the first day of observation, with the highest antifungal index reached 100% at concentration of 25mg/mL and 50mg/mL, respectively. This indicates that water and methanol extracts of picung leaf have antifungal activity. Generally, there was a trend of decrease in antifungal index over time.Key words: antifungal activity, Botryodiplodia theobromae, jabon merah, picung
