Abstract

Global warming that caused by increasing of C02 in atmosphere effects many aspect on organism lives, including insects-plants interactions. The effect of CO2 increased will more complex when interact with another environment factors such as Nitrogen increased and atmosphere temperature increased. Global warming effects on physiology, phenology, distribution, adaptation, and interaction among species. Increasing of C02 gases in atmosphere potentially to rise attack of herbivory insects and effects on their natural enemy. Eventhough, the effect is very species spesific  and specific system on insects-plants interactions. It is needed  holistic understanding to build the strategy for herbivory insects controlled. In the other side, C02 increasing is a ecological issue that caused and effects to human life. It is need proactive attitude and communication to handle this problem together.

Abstract

The aim of this research was to know the diversity of amphibians in Lore Lindu National Park. The research was used survey methods which was located at the conservation area of Kulawi section in the Lore Lindu National Park Central Sulawesi. The result of the research showed that there were five (5) species of amphibians collected which were found and belonged order Anura. These species were Bufo melanostictus, Bufo celebensis, Fejervarya cancrivora, Rana (Hylarana) erythraea, and Kaloula baleata Muller.

Abstract

This research aimed to determine pattern of agroforestry system and agroforestry spesies’s structure and composition of mixed garden practiced by farmer community at various land tenure area. This research was conducted in October to December 2005 in village of Pattalikang, district of Manuju, Regency of Gowa. It was decided to establish four categories of land tenure area based on the preliminary survey and field orientation namely > 0.5 ha, 0.5-1.5 ha, 1.1-1.5 ha, and < 1.5 ha. Method used to set up those categories was Purposive Sampling in which there were 10 plots established for measurement in each type of land tenure area. The size of plot was 20 x 50 m or 0.1 ha. Tree height was measured and species name was recorded to identify the structure and composition of plant species. Herbarium was made for those plant species that have not identified. The research showed that pattern of agroforestry practiced by farmer community was agrisilviculture with irregular plant pattern. Structure and species composition of mixed agroforestry garden at different land tenure area was relatively similar one of each other. The vertical structure consisted of 3 stratum while the species composition were 28 species at land tenure area of < 0.5 ha, 25 species at land tenure area of 0.5-1.0 ha, 26 species at land tenure area of 1.0 ha -1, 5 ha, and 25 species at land tenure area of > 1, 5 ha.

Abstract

This research was aimed to know contribution of forestry sector to Local Government Revenue (Pendapatan Asli Daerah, PAD) at district of Muna in regional autonomy era. The research result is expected to contribute in evaluating and compiling Regional Budget and Expenditure Plan. The result is also intended as an evaluation of forest product restribution policy. This research was carried out in Muna district. Data collected with purpossive sampling using observation technique/survey, interview and discussion with related stakeholders. The data than processed, tabulated and clasified base on with research aim, and analysed descriptively. The results show that the contribution of forestry sector to PAD to Muna district during 2000-2004 in average was 38,88% of PAD in total.

Abstract

Oxidation reaction has been done oxidation on ά-pinena (2,6,6-trimetil bisiklo[3.1.1]hept-2-ena) utilizing oxygen gas flow and NaX zeolite as catalyst. The aim of the research is to study both the application of oxygen flow as oxidant and zeolite NaX as catalyst to produce the oxidation product that can be controlled by regioselektif. The Reaction product and The progress of oxidation reaction was observed using Chromatography gas (GC), Infra red Spectrofotometry and gas chromatography gas – mass spectrograph (GC-MS). The result showed that the main reaction product was 2,6,6-trimetil bisiklo[3.1.1]hept-1-en-3-on. The temperature Condition and the concentration of Zeolite were 110oC and 4% (m/v) respectively. The reaction mechanism for formation 2,6,6-trimetil bisiklo [3.1.1]hept-1-en-3-was estimated conduct through transition state 2,6,6-trimetil bisiklo[3.1.1]hept-1-en-2-hidroperoksida free one molecule of water to form keton carbonil compound.

Abstract

This research aim to to know influence of -ray irradiation sprout of pollen, and also effect to percentage of efficacy of impregnation of hot pepper plant. Result of research indicate that hot pepper plant (LV-2319, LV-2323 have pollen higher viabel generally than hot pepper plant (CK-L, CK-C). This result energy of sprout of pollen and mount impregnation efficacy also become high, that is reach 36,20% (LV-2323) and 28,60% (LV-2319).
