Abstract

The purpose of this research is to compare the intensity attack of G. agamemnon on monoculture and manglid agroforestry patterns, to identify G. agamemnon parasitoid and to compare the level of parasitization on monoculture and manglid agroforestry patterns. The method used is direct observation of manglid with parameters such as G. agamemnon intensity attack on monocultur and agroforestry, morphology identification of parasitoid type and parasitization level on monoculture and agroforestry. The results showed that G. agamemnon attack on monoculture pattern reached 39.25 % and 25.75 % on agroforestry pattern. The type of parasitoid that attacks G. agamemnon larvae is Diaparsis sp. Parasitization of Diaparsis sp. on monoculture and agroforestry manglid pattern were 55.00 % and 66.67%. Keywords: Diaparsis, Graphium, manglid, parasitoid, pest.

Abstract

The multisectoral, multidisciplinary, multi-stakeholder and multidimensional watersheds problems are the consequences of multifunctional watersheds.  The complexity of these problems demanding a system and management approach that appropriate with the characteristics and typology of the watershed. This study aims to analyze the characteristics and typology of Mapili watershed West Sulawesi Province. This research was conducted using surveys, primary, and secondary data collection. Application of geographic information system (GIS) with overlay maps and scoring was used. The results showed that Mapili biogeophysical characterization includes meteorology, morphology, morphometry, hydrology, watershed capability and socioeconomic, cultural and institutional characterization will influence the system of Mapili watershed management. Mapili watershed can be classified into two typology watershed, namely: typology II, which has a low total population density (97 people/km2) with high rainfall (>2500 mm/yr); and typology IV, which has a high total population density (377 people/km2) with low rainfall (<1500 mm/yr). Both typologies have different characteristics of watershed problems. Typology II is generally located in the central area and upstream Mapili and Typology IV are located in the downstream areas of Mapili watershed.Keywords: Watershed characteristic, watershed typology, GIS, Mapili watershed

Abstract

Nickel mining impact in heavy metal pollution on both soil and water. A method that is widely applied to reduce heavy metal contamination is bioremediation. Selection of bacteria that have potential reduction of heavy metal contamination in soil is very important in bioremediation process. The first step to select the potential bacteria is identification of samples. The purpose of this study is to identify existings  bacteria in pond  after nickel mining area  PT. Antam, East  Halmahera.  Methods used in this research are isolation and identification of bacteria by conventional methods includes morphological, physiologica,l and biochemical test. Identification using Bergey’s Manual Determinative.  The results showed there are  6 genera types of bacteria there are Bacillus, Esherichia, Enterococcus, Pseudomonas, Staphylococcus, dan Klebsiella, with 18 species in water of nickel post mining. Morphologically it is dominated by genus Bacillus as 50 % of the species. The identification of bacteria proved an existence of indigenous bacteria which is resistant to heavy metal stress.Keywords: bacteria, soil, water, contamination, post mining, East Halmahera

Abstract

Non-timber forest products (NTFPs) are forest resources which have comparative advantage and in direct contact with the community. Masoi (Cryptocarya masoia) is one of mainstay Papua NTFPs. This essential oil that produced through bark distillation, used as aromatic raw materials for food, medicines, perfume,s and aromatherapy. The demands of masoi oil are high for domestic and foreign market. This study aimed to formulate development strategy of masoi as non-timber forest products in Teluk Bintuni regency, Papua Barat Province, by identifying external factors (Opportunities, threats) and internal factors (strengths, weaknesses). The research applied SWOT analysis methods by identifying external factors (EFAS) and internal factors (IFAS) as strength, weaknesses, opportunities, and threats. Based on SWOT analysis which conducted by calculate score of external factors and internal factors, the suitable strategy was WO strategy which utilized opportunities to suppress the weaknesses at third quadrant. The third quadrant tended turn around by 1). Socialization and training of masoi cultivation on indigenous people, 2). Legal Counseling to increase legal awareness of the community to overcome land disputes.Keywords: strategy, development, masoi, nontimber forest products (NTFPs), SWOT

Abstract

The purpose of this study is to know the potential diversity of wild fauna (birds, butterflies, reptils, and mammals) in THAL. Inventory of mammal, reptile, and butterfly using line transect method while birds were observed by Ponctuels d'Abundance Indices method (IPA). The results showed that the potential fauna can be found in THAL as many as 49 species consisting of 36 species of birds, eight species of butterflies, three species of reptiles, and three species of mammals. From 49 fauna species at least nine species were endemic to Sulawesi and 11 species protected by Indonesian law. In the future development of THAL area, it is expected that management will conserve the condition of wildlife habitat in order to stay natural.Keywords: Diversity, fauna, Kaki Dian, Klabat, North Minahasa.

Abstract

In the forest economics literature, Faustmann formula is highly adopted for profit maximization problem in forest management, mostly in plantation forest. Stylized models of Faustmann formula to be applied in selective logging regime have also been studied extensively in multi-age and multi-species forest. In general, natural forest managers in Indonesia have not adopted the Faustmann formula in their management decisions. Sustainability aspect in natural forest management is applied based on silvicultural consideration, i.e. measuring residual stand that is able to be harvested in the next cutting cycle. This study aims to analyze the application of Faustmann formula in the current selective logging regime in Indonesia (i.e. TPTI), so that the natural forest managers may gain maximum profit and sustainable. This study is a qualitative research based on literature review. The results of this study show that under deterministic growth model (i.e. matrix transition model) and robust damage model (i.e. transition matrix with different damage proportions on each species and diameter class), the Faustmann formula can be applied for selective Logging regime in Indonesia.Keywords: Faustmann formula, selective logging, natural forest, Indonesia
