Abstract

Buffer zone management is an integrated practice of managing forest and agriculture land based on biophysical nature of region and social-culture combination to obtain an optimum forest and agriculture products that support local livelihood economy. The study was to identify the community land use patterns that shapes the buffer zone of Aketajawe Lolobata National Park particularly at Aketajawe block. Sampling villages were determined by stratification based on the distance from the National Park boundary which varied between <3,3-5, and > 5 km. The purposive random sampling was chosen 82 respondents to be interviewed. Land use pattern which applied by communities were divided into six groups according to cultivated commodities i.e. community forest, mixed garden, monoculture garden, intercropping garden, horticulture and rice fields. The differences of these patterns were influenced by background and origin of communities. The indigenous people of Halmahera island used their land as mixed garden while the settler used theirs as rice field and horticulture. Based on the land cover quality, mixed garden pattern was more similar to forest vegetation than another pattern. Rice field pattern gave the largest economic contribution while community forest gave the lowest contribution to the farmer’s income.

Abstract

Most of  non timber forest product (NTFP) utilization taken from natural forests which decrease on productivity annually, including tengkawang producer species which taken from West Kalimantan natural forests. This condition needs an effort to preserve those species from natural population utilization through plantation forest development that require spesific strategy. This study was part of breeding strategy of shorea species producing tengkawang which aimed to species identify and seedling growth evaluation used genetic material from 2 (two) population from West Kalimantan. The research was arranged in 2 (two) steps, i.e.1) species identification used morphology characteristic difference, and 2) seedling growth evaluation (height,diameter,sturdiness). Seedling growth evaluation was arranged in RCBD, with 5 plot (combination of species and source population), contained 25 seedlings and 4 replications (blocks). The result showed that seedlings of shorea species producing tengkawang, i.e. S.stenoptera,  S.macrophylla, and S.gysbertsiana can be different from its stipulae morphology characteristic. Growth of 10 months shorea species producing tengkawang seedlings were significantly different on height and sturdiness. Seedlings height were 67,19 – 88,79 cm, seedlings diameter 9,65 – 10,33 mm and sturdiness 7 – 9,21 in range. The best seedling growth was S.stenoptera and S.macrophylla from Gunung Bunga, West Kalimantan.

Abstract

Tiwoho mangrove forest islocated in north coast of North Sulawesi province.This area functions as life buffer system for community and sustainability of Bunaken National Park. Due to the important and strategic roles of mangrove in protection and ecological functions, therefore, it is needed to know scientific information about mangrove population dynamics. This research aims to know the vegetation composition and structure vegetation of Tiwoho mangrove forest. Data collection used 20x20 m sample plots that were sistematically laid from the sea to the land side up to the highest tidal line. Distance between plots along 25 m. Results showed that at tree level Sonneratia alba had the highest Important Value Index (IVI) of 206,88 % and Brugueira sp of 46,06 %. Although Rhizopora apiculata value is lower than Brugueira sp. But the values of relative frequency of these species are almost similar. It means that both species are frequently found in observation plots. Rhizophora apiculata dominate at pole and sapling levels, but frequency of occurance this species is lower than Brugueira sp in pole level.

Abstract

This research purposes to identify the pathogen causing leaf spot in cempaka seedling and its control technique. Identify cause of disease is necessary to know precise technique control. Identification of disease was conducted in macroscopic appearances and microscopically to determine pathogens. Identification is done by using the determination key of fungi. The results showed that the early signs of leaf spot disease on cempaka seedlings in the nursery are streaks or spots on the leaf surface with distinct boundaries. Leaf spots are formed generally brown surrounded by darker boundaries. The result shows leaf spot disease on cempaka seedling was caused by fungal pathogen Colletotrichum sp. Techniques for controlling the disease can be done by isolating the infected seeds, reducing the intensity of canopy, and using the appropriate fungicides.

Abstract

Aketajawe-Lolobata National Park was selected as one of conservation areas in Indonesia due to its important roles to preserve wildlife natural resources and its unique ecosystem. Our research on fauna diversity was designed to identify bird species diversity that inhabited Tayawi’s watershed within the Aketajawe-Lolobata National Park in North Maluku. We explored the area by using transect method; species identification was carried out by visual and vocal encounter. Fifty five bird species were identified and they belong to 25 families. Among them, 17 species were identified as endemic to Maluku and Halmahera islands. Based on our analysis and field observation, these areas had low fauna diversity. We suspected that illegal logging and hunting might have caused a rapid decrease of the bird population in Tayawi’s watershed area. These can be a serious threat if it is not well-anticipated. Therefore, urgent need is required to discontinue the activities of illegal logging and hunting.

Abstract

Fulfillment the needs of Red Jabon (Anthocephalus macrophyllus (Roxb.) Havil) seeds on the other hand can create an unbalanced ecosystem. The availability of red Jabon seed was becoming a source of food for pests, then it causes an explosion of pests and pathogens. The disease that most often affect red Jabon seeds, both in the nursery and in the field was red leaf spot (antraknose). The initial step to control red leaf spot disease is the identification of causing. Identification method performed by observation of the symptoms in the field, followed by microscopic observation in a laboratory. Based on the identification result, it was known that the disease caused by the fungus Cercospora sp., Colletotrichum sp. and Pestalotia sp. The effect caused by those fungal pathogens was the disruption of the photosynthetic process that ultimately inhibits the growth of red Jabon seeds. The controls which have been done are arranged the watering intensity, isolated the infected seed,and  applied the chemical fungicide.
