Abstract

Undergrowth vegetation analysis in the old coconut stands in the Pari Island wasundertaken, to determine the structure and floristic composition in relation with their habitat characteristics. Physiognomically, the undergrowth vegetation typified by grasses community with Ischaemum muticum (Importance Value: 122.94%) and Imperata ylindrica (Importance Value:  5.45%) to be a dominant and co-dominant species,respectively. Floristically, the grasses community consists of 27 families along with their 56 genera and 58 species. Amongst those, only 15 species belong to a weed component and can be classified as principal and common weed species in the agricultural land in Indonesia. The grasses community has four common families in term of their highestnumber of species, viz Compositae, Euphorbiaceae, Leguminosae and Poaceae.Based on the ordination technique of Principal Component Analysis (PCA) three distinct groups of the vegetation component can be recognized as (i) pes-caprae formation, (ii)Calophyllum formation and (iii) transition community zone. The spatial distribution of prevalent species in relation with their habitat characters was discussed. Generally, the grasses community can be classified into secondary vegetation of the small island.Keywords : Vegetasi bawah, pohon kelapa, kenanekaragaman jenis, mitigasi,pengelolaan terpadu pesisir dan laut, Pulau Pari, Teluk Jakarta

Abstract

The application of high technology (hitech) for solid waste management andtreatment in Singapore is one of examples of solving the municipal solid waste problem. Singapore with more than 4 million inhabitants produced 7676 ton wastes per day in 2001. Now, all the combustible solid wastes goes to the incinerator plant that can convert the heat into electricity. The ash from incinerator and the incombustible solid wastes are transported via waste harbour in Tuas to the Semakau off shore landfill. Also, before incinerating in the plant, the activities of collecting and transporting of munocipal solid wastes are suported by such kind of new technologies for example pneumatic refuse transport system. The typical of the high tecnology is need high cost for building, operating and maintaining and should be operated by high skill staff. Singapore has all the need and also has a strong political will in combating the solid waste problems. So that, Singapore is one of the cleanest metropolitan cities in the world.

Abstract

Artificial (electric) and direct lighting technologies available today have thepotential to greatly reduce the growth rate of electricity consumed through lightingworldwide. While electric lighting has been inefficient throughout much of itshistory, direct (natural) lighting is nearly free and often plentifully supplied by thesun. However, electric lighting systems are necessary when solar lighting is notadequate and these technologies are being greatly improved.One relatively new method of lighting a building’s interior combines both artificialand direct lighting to maximize efficiency is accomplished through the use of aparaboloidal, mirrored dish which actively tracks the sun to concentrate sunlightinto an array of fiber optics.

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

The level of environmental quality is indicated by how much the pollutants enter into and stay in it, that is whether they are still below or already above the regulated pollutants standard. In knowing pollutant concentration in the environment, pollutantmeasurement must be done by employing appropriate instrument and using qualified/ certified operator. Therefore, the role of environmental laboratory is crucial in preparing instrumentation, operator, as well as standard operating procedure (SOP) in order for sampling and analysis of pollutants to work properly and result qualified data. This type of laboratory is strongly determined by how the laboratory is operated with the standard mechanism, called good laboratory practice (GLP). GLP will be met by the laboratory that owns the current state of the art instrumentation, capability and experience of the operator/analyst in conducting sampling and analysis, availability of SOP, capability to control thequality (Quality Control) and to assure the quality (Quality Assurance) of its work and the results. Some of laboratory in Indonesia has received certification from National Committee on Acreditation (KAN). However, the granted certification from the KAN must be first checked whether it is for all or part of the laboratory capabilities. Second, whether during the analysis it is already checked the accuracy and preciseness of the instrument employed. Unlike in developed countries, this type of such check has not so far been done in Indonesia. In term of QualityAssurance, the institution that grants the laboratory certification, for example KAN in Indonesia, will send blind samples to targeted laboratory to analyze how much the concentration of certain pollutants detected by this laboratory. Third, whether the operators have strongly followed the existing SOP. Thus, in order to operate laboratory in a right procedure and accuracy, a lot of work must be done carefully in order to result a qualified data. This paper is going to describe and to evaluate how the environmental laboratory is operated and how their condition in Indonesia.

Abstract

ABSTRACTHigh population growth rate has stimulated the increase of energy consumption. Therefore, the use of renewable energy sources such as methane gas from landfill has also been encouraged. It is necessary that landfill methane gas is purified to increase its concentration. Common method to purify methane gas is water scrubber method. The aim of this research was to evaluate the effectiveness of landfill methane gas purification using a spray water scrubber (water scrubber method), a water column scrubber (bubbling methods) and the combination of both methods to increase the content of landfill methane. The experiment was conducted in the dry season and rainy season. Results of the study concluded that water scrubber was the most effective method for increasing methane gas concentration. The average increase of methane gas in the dry season were 33.32% (water scrubber) and 23.79% (combination of bubbling and water scrubber), and in the rainy season 8.89% (water bubbling) and 2.75% (combination of water scrubber and water bubbling). The increase in methane gas was due to a decrease in CO2 gas. In addition, there was an increase of H2O content in biogas from landfill after the purification process.Keywords: Landfill, methane gas, purification, water scrubberABSTRAKTingginya laju pertumbuhan penduduk telah memacu konsumsi energi yang terus meningkat. Oleh karena itu diperlukan upaya pemanfaatan sumber energi terbarukan, yang salah satunya adalah gas metana yang berasal dari TPA sampah. Keinginan untuk meningkatkan kandungan gas metana TPA diperlukan upaya purifikasi, menggunakan metode water scrubber. Penelitian ini dilakukan dengan tujuan mengetahui efektivitas purifikasi gas metana TPA dengan menggunakan metode pengaliran gas dalam percikan air (water scrubber) dan metode pengaliran gas dalam air atau water bubbling (serta kombinasi keduanya) untuk meningkatkan kandungan gas metana TPA, yang dilakukan pada musim kemarau dan musim penghujan. Hasil penelitian menyimpulkan bahwa water scrubber merupakan metoda yang paling efektif untuk meningkatkan kandungan gas metana. Rata-rata peningkatan gas metana pada musim kemarau dan musim penghujan, berturut-turut sebesar 33,32% (water scrubber), 23,79 (kombinasi water bubbling dan water scrubber), 8,89% (water bubbling) dan 2,75% (kombinasi water scrubber dan water bubbling). Peningkatan gas metana tersebut terjadi karena adanya penurunan gas CO2. Selain itu, terjadi peningkatan kandungan H2O pada biogas dari TPA setelah proses purifikasi.Kata kunci: TPA, gas metana, purifikasi, water scrubber.
