Abstract

Azadirachta indica A. Juss (Apocynaceae) is a large tree of the lowland tropical rain forest of Southeast Asia that occurs in Thailand, the Malay Peninsula, on the island of Java (East Java) and Lesser Sunda Islands. Its economic value was in its wood (timber), and as medicinal plant. The information on genetic diversity of the species is very limited. Hence studies were initiated and genetic diversity estimated using RAPD markers in 27 accessions of A.indica procured from three geographical regions of TN Baluran and Balai Litbang Kehutanan. Seven selected Operon primers (10 mer) generated a total of 133 consistent amplification products ranging from 132 bp to 5.6 Kb. The cluster analysis separated the 27 individuals into 2 clusters. The range of genetic dissimilarityvalue among samples was from 0.07 to 0.33, while genetic distance among populations was from 0.04 to 0.10. These values showed that A. indica from TN Baluran was not genetically diverse population. Key words: Azadirachta indica, genetic diversity, RAPD

Abstract

Maluku province is also famous as a producer of cajeput oil in Indonesia’s number one, but its potential until now have not been optimally utilized in accordance with the carrying capacity of land for public welfare. Melaleuca Cajeputi Roxb have not managed intensively as industrial plants, consequently low production. Based on the results of land suitability assessment, pewilayahan eucalyptus trees on the island of Buru include areas that are not so large, that is 188,743 ha or 20.60% of the total area of the island of Buru, with the details:Land is very suitable (S1) covering 54,832 hectares, or 6 percent of the total land area,mainly scattered in the northern part of Buru District, the floodplain physiography. Enough suitable land class (S2) on Buru Island reached a total area of 45,404 hectares of territory, with the main limiting factor is the rainfall and slope. Class marginal land suitable (S3) with severe limiting factor on regional conditions and slope roots reach a total area of 88,507 hectares.Class of land not available for this moment (N1) reached 513,937 hectares with a very heavy barrier so that if the current efforts will be made to harm the environment or very costly. Spread primarily on physiography tectonics with sloping hills more than 25 percent and its height more than 400 m above sea level. Land Not Available forever (N2) are lands that have very severe limiting factor, so for good both physically and economically impossible to be undertaken.Keywords: capability, suitability, land, cajuput oil

Abstract

Global warming has become an increasingly important issue around the world today due to the rise of anthropogenic greenhouse gases emission, which gives several negative impacts on human life. There are some techniques have been studied and assessed i.e. physical mechanism by injected CO2 to the geological formations, chemical mechanism with artificial tree technology and biological mechanism by increasing the primary production through iron enrichment in high nutrient-low chlorophyll (HNLC) waters as well as mixing of water column below the sea surface. Those technologies, which are well known as Carbon Capture Storage ‘(CCS) technology, are expected to be applied to reduce the oncentration of anthropogenic CO2 in the atmosphere and to minimize the global warming. The Center of Environmental Technology, Agency for the Assessment and Application of Technology (BPPT) will carry out a research concerning CO2 reduction by a phytoplankton culture in a photobioreactor in three years. The main objective of this research is to assess the CO2 uptake capability of tropical phytoplankton. In this paper, we would showed the creteria and design to assembly a photobioreactor esspesially a air lift photobioreactor. To improve performance photobioreaktor, the materials included design criteria and the dynamics of fluids in fotobioreaktor have to considered propoerly. Other the hand, the selection of the most productive species and selection of appropriate media and economically also important to be done. Keywords: global warming, creteria and design, greenhouse gas, air lift photobioreactor

Abstract

After ratifying the Kyoto Protocol, Indonesia has obligation to make report on National GHGs emission for UNFCCC. There are some studies at national level related to GHGs inventory. In this study we calculated GHG (CO2 and CH4) emissions from 5 (five) sectors i.e forestry, energy, industry, agriculture and waste. Calculation use 2006 IPCC method with local values for verification or enhanced the Tier of method. The local values are, forestry allometric equation, emission factor of paddy field, generation and composition of municipal solid waste, solid waste management as well. Calculation result of GHGs emission in this study is 827,058 Gg/year in the term of CO2 equivalent. This numbers isestimated arround 60% of the realistic numbers due to the accuracy of the transportation data and unaccounted peat fire data in the study. Carbon emission from peat fire is the biggest emission. From all sector has calculated, forestry sector is the biggest CO2e emmitor with contribute arround 58%, follow energy sector (25%), agriculture (8% ),industry sector (6%), and waste sector (3%). The proportion of distribution each sector can change if the data more broad the calculation include more detail in sub sectors.Key words : GHGs Emissions, Local Values, Sector Contribution

Abstract

Cassava peels is one of agriculture waste having potency as feed for poultry. Cassava peels represent waste product from cassava industry with amount 1,998 million ton in the year 2006 in Indonesia (10 percentage of corm of yielded cassava). The weakness of cassava peels are low crude protein content, less palatable for ruminant and have voluminous characteristic. One of the effort to increase usefulness of cassava peels is by using cassava peels as fibre source in pellet complete ration for poultry. The aim of this research was to know best level from utilization of cassava peels as physic quality in poultry complete ration. This study used Completely Randomized Design that consistsof three treatments and three replications. The treatments were: 1). Control feeds + 0% cassava peels (R1), 2). Control feeds + 30% dry matter cassava peels (R2), 3). Control feeds + 30% boiling matter cassava peels (R3). Data was analysed with ANOVA and continued with Duncan Test. The result indicated that effect of water content pellet ration with moisture tool is higher than using infrared tool. Pellet rations with dry matter and boiling matter control treatment before saving have physic qualities that still meet the quality standar of poultry ration. Eventhough, on treatment after saving, the physic qualities decrease and relatively less meet the quality standar of poultry rationKey word: waste, cassava peels, poultry ration, pellet complete.
