"Skripsi ini membahas mengenai analisis pengaruh temperatur terhadap perilaku gas karena penguapan minyak isolasi transformator. Pada transformator berpendingin minyak biasanya menghasilkan gas-gas yang mudah terbakar (combustible gas) seperti hidrogen, methane, ethane, ethylane, karbon dioksida, dan karbon monoksida yang dikenal dengan istilah fault gas. Metode pengujian yang digunakan adalah Dissolved Gas Analysis (DGA) dan konsentrasi gas diukur dengan Gas Chromatograph (GC). Metode pengujian DGA akan mengidentifikasi jenis dan jumlah dari fault gas.
Dalam skripsi ini pengujiaan diutamakan pada konsentrasi gas methane karena merupakan gas yang mudah terbakar. Hasil dari uji DGA adalah data konsentrasi berbagai jenis fault gas terutama gas methane yang nantinya akan dianalisis dan diolah untuk memperoleh informasi akan adanya indikasi kegagalan-kegagalan termal dan elektris pada transformator daya.
Temperatur optimum minyak trafo yang diujikan yaitu sebesar 115°C. Pada temperatur tersebut, konsentrasi gas methane yang mudah terbakar berada dalam kondisi minimum. Tapi pada temperatur diatas 115°C konsentrasi gas methane kembali mengalami peningkatan. Hal ini dapat menyebabkan kegagalankegagalan termal dan elektris. Sehingga perlu dijaga agar temperatur minyak trafo tidak melebihi temperatur optimum dari minyak trafo tersebut yaitu sebesar 115°C.

This skripsi deals with the analysis influance temperature on the behaviour of gas due to evaporation of oil isolation transformer. The transformer oil is usually refrigerated produce gas that are flammable (compustible gas) such as hydrogen, ethane, ethylane, carbon dioxide, and carbon manoxide which is known by name fault gases. The test methode used is the Dissolved Gas Analysis (DGA) and the concentration is measured by a Gas Chromatograph (GC). The DGA testing methode will identify the type and the amount of fault gases.
In this skripsi examine take precedence on the concentration of methane gas which is flammable. The result of the test data is the DGA concentration range of fault gases primarily methane gas that will be analyzed and processed to obtain information for indication of failure from electrical and thermal power at the transformer.
The optimum temperature of the transformer oil to be tested is a 1150C. On the temperature, the concentration of methae gas which is flammable under minimum. But on the temperature above 1150C the concentration of methane has increased again. This can lead to failure of thermal and electrical. So that needs to be maintained that the temperature does not exceed the transformer oil temperature optimum of the transformer which is 115°C.

"Berdasarkan penelitian terdahulu, sektor air memegang peranan yang signifikan terhadap emisi gas rumah kaca (GRK) dengan 58% dari total emisi GRK sektor air berasal dari penggunaan akhir air. Penelitian mengenai emisi GRK dari sektor air yang telah dilakukan di negara berkembang terbatas pada area yang airnya disediakan oleh instalasi pengolahan air.
Pada penelitian ini dilakukan perhitungan terhadap emisi GRK yang diasosiasikan dengan penggunaan akhir air dari area yang menggunakan air tanah sebagai sumber air. Data dikumpulkan dari 100 rumah tangga yang terletak di kecamatan Cinere, Kota Depok, Jawa Barat menggunakan metode sampel acak. Survei kuesioner dan wawancara dilakukan untuk mendapatkan data untuk setiap penggunaan akhir air dan konsumsi energi dari pemakaian peralatan air. Emisi GRK eksisting dihitung berdasarkan data yang terkumpul dan dilakukan perbandingan antara skenario intervensi.
Didapatkan hasil yakni rata-rata konsumsi penggunaan akhir sebesar 228,2 liter per orang per hari dengan aktivitas mandi merupakan konsumsi air terbesar. Emisi GRK dari penggunaan akhir air yang dihasilkan sebesar 0,379 kg CO2/orang/hari dengan pemanasan air sebagai sumber utama. Dua skenario intervensi dilakukan untuk menurunkan emisi GRK, skenario pertama dapat mengurangi emisi GRK hingga 1% dan skenario kedua dapat menurunkan emisi GRK hingga sebesar 66%.

Previous studies showed that the water sector plays a significant role in Greenhouse Gases (GHG) emissions with household water end-uses contributes 58% of total GHG emissions. Studies on GHG emissions from the water sector in developing countries were limited to areas where the water is supplied by a water treatment plant.
We attempted to calculate GHG emissions associated with household water end-uses from the area that use groundwater as the main water source. Data were collected from 100 households in Cinere District, Depok City, West Java using random sampling technique. Questionnaire surveys and interviews were conducted to obtain the data for each water end-use consumption and energy consumption from water appliances usage. Existing GHG emissions were calculated based on the data collected and comparisons were made between existing GHG emissions and intervention scenarios.
The results showed that the average household water end-uses consumption for the study area was found to be 228,2 litres per capita per day with bathing activity consumed the largest amount of water. GHG emissions associated with household water end-uses was found to be 0,379 kg CO2 capita/day and mainly resulted from water heating. Two intervention scenarios to minimize GHG emissions were evaluated, the first scenario could reduce GHG emissions by 1% and scenario two could reduce GHG emissions up to 66%.

"The high temperatures generated in gases by shock waves give rise to physical and chemical phenomena such as molecular vibrational excitation, dissociation, ionization, chemical reactions and inherently related radiation. In continuum regime, these processes start from the wave front, so that generally the gaseous media behind shock waves may be in a thermodynamic and chemical non-equilibrium state.
This book presents the state of knowledge of these phenomena. Thus, the thermodynamic properties of high temperature gases, including the plasma state are described, as well as the kinetics of the various chemical phenomena cited above. Numerous results of measurement and computation of vibrational relaxation times, dissociation and reaction rate constants are given, and various ionization and radiative mechanisms and processes are presented. The coupling between these different phenomena is taken into account as well as their interaction with the flow-field. Particular points such as the case of rarefied flows and the inside of the shock wave itself are also examined. Examples of specific non-equilibrium flows are given, generally corresponding to those encountered during spatial missions or in shock tube experiments.

"Dalam pidato pada KTT G20 di Pittsburgh, Amerika Serikat, 25 September 2009, Presiden Susilo Bambang Yudhoyono menyatakan bahwa Indonesia secara sukarela berkomitmen untuk menurunkan emisi gas rumah kaca (GRK) sebesar 26 persen pada tahun 2020 dari tingkat business as usual (BAU) dengan usaha sendiri. Target ini bisa ditingkatkan menjadi 41 persen apabila ada bantuan luar negeri yang memadai. Tekad tersebut diutarakan di tengah ketidakpastian implementasi hasil-hasil perundingan di bawah Konvensi Kerangka Kerja Perserikatan Bangsa-Bangsa tentang Perubahan Iklim (UNFCCC).
Terkait dengan komitmen tersebut, pemerintah Indonesia telah bertekad untuk menerapkan pembangunan berkelanjutan (sustainable development). Secara domestik, prinsip pembangunan ini tidak hanya menguntungkan dari aspek lingkungan, tetapi juga ekonomi dan sosial. Penerapan pembangunan berkelanjutan berkorelasi positif dengan penurunan emisi GRK, namun juga dihadapkan dengan target pertumbuhan ekonomi. Dengan demikian, komitmen penurunan emisi GRK merupakan tantangan bagi Indonesia agar target pertumbuhan ekonomi sebesar 7 persen dapat tercapai. Sedangkan secara internasional, Indonesia berharap mampu menunjukkan kepemimpinannya dan menjadi pendorong bagi negara-negara lain, terutama negara maju untuk menurunkan emisi GRK global.
Penelitian dalam tesis ini didesain atas dasar riset kebijakan (policy research) dengan menggunakan metode kualitatif dengan teknik analisis deskriptif. Dari hasil penelitian diperoleh kesimpulan bahwa target penurunan emisi GRK nasional sebesar 26 persen berpotensi tercapai. Selain sebagai negara yang memiliki hutan terluas ketiga di dunia, upaya-upaya penurunan emisi di bidang lainnya telah mendorong pencapaian target tersebut. Kesuksesan dalam program penurunan emisi GRK ini tidak hanya menguntungkan secara domestik, tetapi juga akan menempatkan Indonesia dalam posisi penting dalam kerjasama internasional menghadapi tantangan perubahan iklim global.
Dengan komitmen penurunan emisi GRK dalam rangka pembangunan berkelanjutan di Indonesia, maka prinsip ”pemenuhan kebutuhan generasi sekarang tanpa merugikan kebutuhan generasi-generasi mendatang” menjadi pedoman dalam pelaksanaannya. Itulah sebabnya, ketika merumuskan kebijakankebijakan dalam pembangunan, perlu melibatkan perhitungan lingkungan, yang diharapkan akan mendukung terciptanya ketahanan ekonomi dan sosial yang berkelanjutan. Ketahanan ekonomi dan sosial berkontribusi bagi terciptanya ketahanan nasional yang mantap.

In a speech at the G20 Summit in Pittsburgh, the United States, September 25, 2009, President Susilo Bambang Yudhoyono said that Indonesia voluntarily committed to lowering emissions of greenhouse gases (GHG) by 26 percents by 2020 from the level of business as usual (BAU) with his own business. The target could be increased to 41 percents when there is sufficient foreign aid. The determination expressed in the midst of the uncertainty of the implementation of the results of the negotiations under the United Nations Framework Convention on climate change (UNFCCC).
Associated with that commitment, the Government of Indonesia has committed to implement sustainable development. Domestically, the principle of this development not only benefits from the environmental aspect, but also economic and social. The application of sustainable development correlates positively with decreased GHG emissions, but it also faced with a target of economic growth. Thus, the emissions reduction commitment is a challenge for Indonesia to target economic growth of 7 percents could be achieved. Meanwhile, Indonesia wished to demonstrate his leadership and became the catalyst for other countries, especially developed countries to lower the global GHG emissions.
The research in this thesis is designed on the basis of policy research using qualitative method with descriptive analysis techniques. Of the research results, obtained the conclusion that the 26 percents of national GHG emissions reduction target will be potentially achieved. Aside from being a country that has the world third largest forest, the efforts to decrease emissions in other sectors has been encouraging the achievement of the target. Success in this program of GHG emissions reduction not only benefits domestically, but will also bring Indonesia as an important country in the international cooperation in facing the global climate change.
GHG emission reduction commitment in order sustainable development in Indonesia, then the principle of fulfilment of the needs of the present generation without harming future generations needs to be guidelines in its implementation. That is why, when formulating policies in development, it is necessary to involve the environmental accounting, which is expected to endorse the creation of an economic and social security. Economic and social security contribute to thcreation of a national resilience steadily.
