Abstract

The increased number of tourists in Batu City has resulted in traffic congestion, which led to the increase of emission contributing to GHGs effect and caused global warming. According to Presidential Regulation Number 71 of 2011, each region is required to conduct a national inventory of GHGs emission, in order to determine the appropriate adaptation and mitigation strategies in reducing the GHG emission. This research aimed to reduce the GHGs emission and to determine the appropriate adaptation and mitigation strategies in Batu City especially in the transportation sector. IPCC Guidelines 2006 was used as the method to calculate GHGs emissions. Such method allowed the researchers to determine the emission level by using secondary data obtained from the relevant institution. Determination upon adaptation and mitigation strategies was on the basis of several scenarios of emission level reduction while the prioritized strategy selection was based on the Analytical Hierarchy Process method. This research revealed that the GHGs emission with business as usual scenario in 2030 contributed by transportation reached 2,072.64 Gg of CO2 while the greatest reduction of GHG emissions amounted to -6.13% taken from the scenario of Intelligent Transport System application. More importantly, the researchers figured out that the prioritized adaptation strategies should be the improvement of Urban Open Space and public transportation rejuvenation for the mitigation.

Abstract

RSUD dr. Soetomo merupakan aset sangat penting di kota Surabaya sebagai salah satu fasilitas kesehatan kota dengan skala pelayanan tingkat provinsi. Lokasi RSUD dr. Soetomo berada di pusat aktifitas kota yang sangat dekat dengan fasilitas transportasi, perdagangan, pendidikan dan fasilitas lainnya. Padatnya area sekitar terutama dari aktivitas transportasi yang melalui empat ruas jalan di sekeliling RSUD dr. Seotomo mengakibatkan potensi tingginya kebisingan pada fasilitas kesehatan ini. Mengacu pada Keputusan Menteri Lingkungan Hidup RI No. 48 tahun 1996 tentang metode pemantauan dan baku tingkat kebisingan di area rumah sakit maka dilakukan penelitian kebisingan di kawasan sekitar RSUD dr. Soetomo. Hasil penelitian ini kemudian dikorelasikan dengan nilai ambang baku mutu kebisingan sesuai dengan nilai kebisingan maksimum di area rumah sakit. Data primer tingkat kebisingan diambil di beberapa titik lokasi di jalan raya sekitar area rumah sakit. Data-data diperoleh digunakan untuk menghitung nilai intensitas kebisingan ekivalen siang hari (Ls) dan malam hari (Lm), serta intensitas rata-rata kebisingannya per hari (Lsm) didapatkan nilai 73dB(A) . Nilai Lsm diolah menjadi peta kebisingan menggunakan software surfer dan dianalisis pola penyebaran kebisingan terutama dari sumber lalu lintas..

Abstract

Dispersi polutan pada udara ambien dipengaruhi oleh ketinggian lapisan inversi yang membatasi ruang mixing height di Kota Surabaya. Ketinggian lapisan inversi dipengaruhi oleh faktor meteorologi dan kestabilan atmosfer di suatu daerah. Tujuan dari penelitian ini adalah untuk menganalisis hubungan perubahan kecepatan angin dan kekuatan radiasi terhadap ketinggian lapisan inversi dan kualitas udara ambien di Kota Surabaya. Metode yang digunakan untuk analisis korelasi dalam penelitian ini adalah metode korelasi Pearson. Data ketinggian lapisan inversi didapatkan dari profil temperatur terhadap ketinggian hasil pengukuran radiosonde BMKG Juanda pada tahun 2009 hingga 2014. Analisis korelasi yang dilakukan diasumsikan dalam keadaan normal sehingga data yang digunakan adalah data hasil pelingkupan pada pukul 00.00 WIB dan 12.00 WIB dengan nilai persentil 10% dari tahun 2009 hingga 2014. Lapisan inversi pada Kota Surabaya kemungkinan merupakan lapisan subsidence inversion. Lapisan inversi tersebut memiliki korelasi berbanding terbalik pada pukul 00.00 WIB dan korelasi berbanding lurus pada pukul 12.00 WIB terhadap kecepatan angin, sedangkan untuk kekuatan radiasi tidak berkorelasi. Korelasi ketinggian lapisan inversi dengan kualitas udara ambien SO2 berbanding terbalik, namun tidak berkorelasi dengan NO2 dan O3.

Abstract

Inventarisasi emisi dilakukan dengan mendaftar besaran polutan dari sumber pencemar dari sektor energi, yaitu transportasi on-road, transportasi off-road, dan sektor limbah yang meliputi limbah padat domestik dan limbah cair domestik. Rentang waktu invetarisasi adalah tahun 2006 hingga tahun 2016. Perhitungan menggunakan worksheet Atmospheric Brown Clouds (ABC) – Emission Inventory Manual (EIM) Excel 2013 dan worksheet IPCC 2006 Guidelines for National Greenhouse Gas Inventories (GL) Excel. Identifikasi menunjukkan NOX dan CH4 berasal dari pembakaran kurang sempurna pada transportasi on-road maupun off-road. Fluktuasi emisi sektor transportasi on-road sangat bergantung pada jenis kendaraan, sedangkan sektor transportasi off-road sangat bergantung pada tipe pesawat. Fluktuasi emisi sektor limbah padat domestik bergantung pada efisiensi pembakaran di insenerator, sedangkan faktor emisi limbah cair domestik bergantung pada bangunan pengolahan. Alternatif yang disarankan pada sektor off-road berupa menejemen LTO (kegiatan taxi). Pada transportasi on-road, yaitu realisasi pengadaan dan penggunaan kereta api.

Abstract

Communities in coastal areas use rain water and ground water to meet the needs of clean water. Precipitation occurs only during the rainy season. The ground water is brackish because of seawater intrusion. This is a problem for this community. Therefore, appropriate water treatment technology is needed especially during the dry season. This research was aimed to measure the influence of the length of long aluminium condenser pipe and the water thickness to the brackish water distillation yield. Variables which were tested were water thickness of 0.5, 1 and 1.5 cm and the length of aluminium pipe condenser of 260, 320, and 380 cm. Two types of glass roofs of were applied. One roof was flat, and the other had an of angle 600. The results showed that the sloped roof produced the highest water volume, with an average of 1045 mL/m2. The percentage of condensate volume produced from distillator with pipe lengths of 260, 320, and 380 cm were 50%, 96%, and 98.3% respectively. Water thickness of 1 cm yielded the highest water volume of 1102.1 mL/m2. The highest distillation rate was 0.167 L/m2 hour.

Abstract

One technique to eradicate SO2 contaminant is gas absorbtion system with liquid, for instance Spray Tower Absorber. The research was performed to examine changes value pH adsorber and SO2 efficiency removal within 90 minutes using solar oil 100% with initial pressure of fuel tank = 60, 80 and 100 psi; and flow, water volume, nozzle = 3,5 and 7 L/minutes. Absorber used in this experiment was 0,0006% H2O2 solution. The result shows that pressure and flow absorber affect the absorbtion efficiency for real. Initiate pressure of fuel tank that was greater within time had caused the decrease of absorbtion efficiency faster. The value of pH absorber after being used for absorbtion within 90 minutes was approximately 6,79 because of the raw water buffer originated by acidity and hardness. For efficiency more than 70%, lowest pH absorber was on range 5,59-6,25 and total recirculation for flow 3 L/minutes was maximum 17 times, flow 5 l/minutes was 34 times and for 7 l/minutes was maximum 56 times of recirculation.

Abstract

The largest emission from the petroleum production process is dominated by nitrogen oxide (NOx) gas which accounts for 60% of the total emissions. In this research, an assessment of the impacts that occur from petroleum production activities is carried out using the Life Cycle Assessment (LCA) method. In this study, the identification of environmental impacts was carried out using the SimaPro 9 application software and the midpoint-based assessment. In the midpoint assessment, 1 method is used, namely the CML-IA Baseline method. Life cycle impact assessment (LCIA) or impact assessment using midpoint assessment includes global warming, human toxicity, photochemichal oxidation, ozone layer depletion, acidification, eutrophication, abiotic depletion, and abiotic depletion (fossil fuel). Emissions analyzed include CO2, CH4, NOx and SOx. In this study, the scope of analysis used from the process system is cradle to gate. The results of the analysis resulted in the greatest impact value coming from unit A power generator. The largest impact category from the CML-IA Baseline method is acidification. The results of the sensitivity check analysis resulted in the value of both variations above 10%, namely 16% of each variation. The recommended alternative program scenario is cogeneration technology and nonselective catalytic reduction (NSCR) because it can reduce acidification by 69.81%, eutrophication 69.82% and human toxicity 69.40%.

Abstract

Climate change is a global issue that affects various sectors, including the electricity sector, with one of the impacts of climate change being the increased risk of landslides influenced by rainfall, land use, slope gradient, and soil type. This research aims to assess the landslide risk in East Kalimantan on electricity infrastructure and formulate adaptation strategies for these landslides. The research method is a quantitative analysis and spatial approach by combining historical data and climate projections up to the year 2060 using the CMIP6 dataset scenarios SSP2-4.5 and SSP5-8.5. Data processed using Geographic Information System (GIS) to produce landslide risk maps for both current conditions and projections. The determination of adaptation strategies is carried out through a combination of SWOT Analysis and Analytical Hierarchy Process (AHP) methods. This research shows that the projection of landslide risk class areas in most parts of East Kalimantan is predominantly in the moderate risk class with an area of 58.16% and the high-risk class with an area of 26.43%. The priority strategies for landslide adaptation in the development of electrical infrastructure are chosen based on the analysis of three aspects: the optimization of DPT development and other supporting technologies in a planned and integrated manner, the preparation of a roadmap for prioritizing the reduction of extreme operational risk points as part of efforts to adapt to the projected increase in landslide risk, and the utilization of evaluation results from periodic monitoring and field inspections to support risk-based electrical infrastructure development planning.
