Abstract

Perkembangan teknologi web semakin pesat baik teknologi web berbasis klien ataupun server. Perkembangan tersebut tidak lain bertujuan untuk meningkatkan mutu informasi yang dikelolanya. Web semantik adalah salah satu solusi untuk meningkatkan mutu informasi dari sebuah web. Karena dengan konsep ini informasi disajikan dalam bentuk struktur orisinil sehingga informasi dapat dipahami oleh manusia dan mesin. Yang dimaksud dengan informasi dapat dipahami oleh manusia dan mesin adalah bahwa keduanya dapat memahami arti semantik dari informasi yang dikandung di dalamnya. Pada penelitian yang dilakukan oleh Yinghui Huang dijelaskan bahwa metoda penyimpanan dibagi menjadi tiga, yaitu: metoda berbasis memori; metoda berbasis file; dan metoda berbasis relasi basis data. Namun pada penelitian tersebut hanya menitikberatkan pada definisi, model dan metoda penyimpanan saja. Pada penelitian ini peneliti akan mengimplementasikan bagaimana melakukan proses penyimpanan dan pengambilan ontologi menggunakan metoda berbasis file. Penelitian ini dibagi menjadi tiga tahap yaitu: perancangan ontologi; proses render, dan penyimpanan dan pengambilan Triple; dan evaluasi. Luaran yang diharapkan dari penelitian ini adalah menghasilkan cara atau metoda untuk mengimplementasikan proses penyimpanan dan pengambilan ontologi berbasis file menggunakan Java dan Jena.

Abstract

A total of 92% of diesel fuel consumption in Jakarta is dominated by public transportation, particularly medium-sized bus. Based on emission factor and distance value, the amount of emission from vehicle use is 17.078,27 tons of NO2, 15.786,63 tons of CO, 2.009,21 tons of PM10, and 1.334,69 tons of SO2, which give high risk to community’s health. The objectives of this research are: (1) to estimate air pollution loss value from diesel-fueled public transportation’s emission, and (2) to estimate tax value of diesel-fueled vehicle in Jakarta to internalize air pollution loss. The research method used was economic valuation analysis and internalization of economic loss. The estimation of economic loss from air pollution from Metro Mini emission based on pollutant cost is IDR 2,17 billion/year, while based on community’s health cost is IDR 12,45 billion/year. The estimation of tax value which internalized the loss from air pollution is IDR 1.301.955/vehicle/year (based on pollutant cost) or IDR 4.617.119/vehicle/year (based on community’s health cost).

Abstract

This paper explores the implementation of refinement theory in questions composition for semantic webbased Arabic Learning game. The refinement theory is used to assess the degree of sophistication of the game, while semantic web is a concept that improves web document into web data. In this paper, a simple ontology about game questions composition is developed by implementing refinement theory to distinguish the difficulty of each level. This, hopefully, will motivate players to continue playing their game into the next level. This research conclude that the relation between value of R and question complexity is a negative correlation. The higher the value of R, the lower the question complexity.

Abstract

Industrial activities are sources of air pollution. Pollutants dispersion in air influenced by meteorological condition, such as wind speed, wind direction, air temperarture, air turbulence and atmospheric stability. Air quality monitoring is important in controling the worst condition of pollutants concentration. Air quality monitoring is not easy to do, because it is time consuming, costly and need technology, so that air quality model is developed as an alternative air quality monitoring. This research used gaussian model, a model for predicting pollutant concentrations in downwind area. This model is applied in cement industry, focusing on major pollutants of the cement industry. Sources of pollutants consist of dust, SO2 and NOx. The modeling results showed maximum ground level concentration of dust, SO2 and NOx occur at night (7-10 PM). The maximum ground level concentration of dust, SO2 and NOx at night respectively were 13.16 μg / Nm3, 32.69 μg / Nm3, 100.21 μg / Nm3 (N1 stack) and 14.65 μg / Nm3, 36.65 μg / Nm3, 128.10 μg / Nm3 (N2 stack) based from downwind scenarios at night when atmospheric condition was stable. The distance where the maximum ground level concentration occured has a strong correlation with wind speed (-0.82 ≤ r ≤ -1). Based on gaussian model output, air quality monitoring should be executed at night time (stable atmospheric condition) and located at ground level where maximum concentration occured. Increasing 50m of stack can decrease 57% pollutant concentrations in stable condition.

Abstract

Ca-bentonit adalah jenis bentonit dengan sifat penyerapan yang baik. Sifat tersebut dapat ditingkatkan dengan mengaktifkannya melalui penambahan asam, tetapi asam apapun yang dipilih memiliki potensi untuk mencemari lingkungan. Penelitian ini mengkaji pengelolaan air limbah bentonit dengan 98% H2SO4 sebagai aktivator. Karena produksi yang besar, berkelanjutan dan  metode trial and error dalam mencari solusi akan membutuhkan waktu yang lama, diusulkan pemodelan sistem dinamik. Pemodelan menggunakan software Powersim Studio 7 mengacu pada data konsentrasi H+ dan jumlah bahan penetral. Model simulasi menghasilkan ilustrasi bahwa pengolahan air limbah yang efektif dan efisien adalah mengganti metode pengenceran air limbah menjadi 126 m3 / 3 ton bentonit dan penambahan campuran NaOH-kapur yang diatur secara bertahap. Netralisasi optimum didapatkan pada penambahan 961,9 kg NaOH untuk meningkatkan pH air limbah hingga pH 3 kemudian diikuti dengan penambahan 40,31 kg kapur hingga pH 6,5  sehingga perubahan pH dan waktu pengerjaan tetap terkontrol. Biaya total pengolahan optimum membutuhkan biaya total Rp 44.100.716/3 ton bentonit yang diproses.

Abstract

Indonesia as one of the developing countries has a high dependence on petroleum fuels derived from petroleum refinery as the main energy source. the use of foil in Indonesia is dominated to meet the needs of transportation vehicles. Fuel oil as a source of energy into the spotlight in the world lately because of the impact of environmental degradation that arise from the utilization. The industrial activity of fuel oil production in refineries is inseparable from the environmental impacts. The oil processing process at the refinery is the second highest emission contributor after the use of fuel oil itself during its product life cycle. In this research LCA analysis is conducted for the production of gasoline (bensin) and gasoil (diesel) vehicle fuels during processing at the refinery to compare the environmental impact of each type of fuel. From the result of LCA analysis, it is known that from two types of vehicle fuel, to produce 1 kilo litter of gasoline (bensin) type more energy and produce higher emission compared to diesel type gas (gasoil) fuel production. The gasoline fuel produced in the platformer unit is the product that has the highest emission contribution in its production process with greenhouse gas emissions of 1 Ton CO-2eq and the acid gas emissions of 0.001 Ton SO-2eq per 1 kilo litter of the resulting product.

Abstract

This paper proposes an online game design that has resources with interoperability. Interoperability means the resources can share, re-used, and interlinked with another Unified Resources Identifier (URI). The game design is constructed by utilizing Linked Data concept where the resources are developed in the form of ontology. The resources are developed by both creating manually using Protégé and re-using from another URI’s. To get the resources from another URI’s SPARQL can be used through Apache Jena Fuseki server. SPARQL is a query used for Resource Description Framework (RDF) or Web Ontology Language (OWL). The result shows that retrieval data/information process by using SPARQL works well. The resources from another URI’s can be used and integrated with local resources. It means the quality of information knowledge is increasing in interoperability, where the resources can be shared, re-used, and interlinked.

Abstract

Cement production was a process that requires huge thermal energy and produces high greenhouse gas emissions. Co-processing or utilising alternative materials and alternative fuels for the combustion process in kiln was a solution to meet energy needs and reduce greenhouse gas emissions in the cement industry. This study aimed to analyze input, output, environmental impacts of cement production and calculate CO2-eq reduction from the system used alternative fuels on co-processing. The method used to determine differences and calculate CO2-eq reduction due to co-processing was life cycle assessment (LCA) and system approach. Based on the results of the LCA, the case 1 that used 100% coal energy required 3.50 GJ/ton-cement, 126 kWh/ton-cement, 2.19 L-diesel-oil/ton of cement and emited 0.84 ton-CO2-eq/ton-cement. Case 2 that had been substituted alternative fuels (saw dust) required 3.03 GJ per ton of cement, 118 kWh per ton of cement, 1.44 L diesel oil per ton of cement and emited 0.92 ton-CO2-eq per ton of cement. The results of global warming impact of  case 2 was higher than case 1. The assumption of  climate neutral made reduction global warming impact of case 2 by 14.65% and decrease CO2 emissions annually in plant by 71,601 tons CO2/year.  This result show that utilization of saw dust as biomass of climate neutral can be applied as an input for overall company specific emissions calculation to meet government regulation.
