Abstract

Di era informasi global saat ini, manusia sangat menginginkan efisiensi waktu dan tenaga dalam berbagai hal termasuk dalam berwisata. Untuk itu, teknologi komunikasi dan informasi (ICT) dapat berkembang dengan cepat karena dapat memenuhi kebutuhan pengguna tersebut. Keberadaan teknologi ICT dan banyaknya pengguna Internet menjadi peluang dan tantangan bagi pengembangan sektor pariwisata. Peluang ini telah dimanfaatkan dengan sangat baik oleh perusahaan penyedia jasa perdagangan sehingga banyak yang menjadi bagian dalam penggunaan e- commerce untuk memasarkan berbagai produk barang dan jasa termasuk pariwisata. Provinsi Banten merupakan provinsi yang terletak di ujung barat Pulau Jawa sehingga dikelilingi oleh pantai yang dapat digunakan sebagai wahana pariwisata, untuk dapat terus meningkatkan kunjungan pariwisata Banten maka pemanfaatan teknologi ICT khususnya e-commerce untuk mengembangkan potensi pariwisata di Banten harus dioptimalkan. Penelitian ini bertujuan untuk melihat pemanfaatan e-commerece di Pariwisata Banten dengan menggunakan E-Servqual yang kemudian diterjemahkan ke dalam diagram Importance-Performance Analysis (IPA). Hasil IPA menunjukkan bahwa kualitas e-commerce wisata Banten dapat dikatakan sudah cukup baik, hal ini terlihat bahwa 18 dari 28 atribut sudah berkinerja baik.

Abstract

Indonesia is a country with the third largest tuna production in the world. Fish oil as a fishery product processing waste is a potential material for making biodiesel because it has a high fat content. In this research, biodiesel was made from bio-oil from tuna waste through esterification and transesterification processes at 60°C, stirring speed 360 rpm with a reaction time of 2 hours. The purpose of this study was to determine the levels of Free Fatty Acid (FFA) contained in bio-oil from tuna waste and to determine the effect of the size of the natural zeolite catalyst in the transesterification process on the characteristics of the biodiesel produced. The variables used were the size of the zeolite catalyst 10 - 20, 30 - 40, 50 - 60, 70 - 80, 100 - 120 mesh. From the research results, it can be concluded that the smaller the zeolite catalyst size, the resulting biodiesel is closer to the biodiesel standard and the size of 100-120 mesh which is very close to the SNI 7182: 2015 biodiesel standard with a density value of 849.6 kg/m3, kinematic viscosity 3,413 cSt, moisture content. 0%, acid number 1.10 mg.KOH /gr, flash point 75 ° C, calorific value 8.240 Cal/gr.

Abstract

The increase in the population of Indonesia is proportional to the increase in the amount of waste produced. Municipal solid waste (MSW) especially organic waste, can be used as solid fuel by means of the torefaction process. Torefaction is a thermo-chemical heat treatment method for biomass conversion that takes place at a temperature of 200oC to 300oC under conditions of atmospheric pressure and in the absence of oxygen. The purpose of this study was to determine the effect of moisture content on calorific, proximate and ultimate values ​​of torefaction samples using municipal solid waste. Setting the water content in the mixed sample (30% rice + 70% wood) with variations in moisture content of 30%, 40%, and 50%; and rice and wood samples with variations in moisture content of 40% and 50%. The torefaction was carried out at a temperature of 300oC for one hour and inert gas N2. Torefaction products have been tested contain of the calorific value, proximate testing, and ultimate testing. The results obtained were the best calorific value in the rice sample, the moisture content of 40% was 6351.1 cal / g or equivalent to sub-bituminous coal. The proximate and ultimate results of the best heating value are rice samples with 40% moisture content, fixed carbon 62.95%, volatile matter 27.85%, moisture 7.06%, ash 2.14%, carbon 71.85%, hydrogen. 2.80%, nitrogen 3.17%, and sulfur 0.05%. The calorific value calculation method that is almost close to the test results is the Dulong method, with an average error percentage of 1.63%.

Abstract

Nilai kalor yang dimiliki oleh biogas sangat mempengaruhi lamanya waktu proses pembakaran. Beberapa penelitian telah dilakukan untuk meningkatkan nilai kalor yaitu dengan menurunkan kadar zat pengotor yang terkandung bersama biogas. Dalam penelitian ini dilakukan upaya peningkatan nilai kalor biogas dengan menggunakan steel wool sebagai adsorben dengan variasi massa steel wool (500 gram dan 600 gram) dan variasi laju aliran biogas (1 lpm, 2 lpm, dan 3 lpm). Peningkatan nilai kalor biogas sebelum dan sesudah pemurnian ditentukan dengan water heating test. Hasil penelitian menunjukan peningkatan nilai kalor diperoleh pada filter dengan massa adsorben 600 gr dan laju aliran biogas 1 lpm, dimana nilai kalor meningkat sebesar 36.19%. Sedangkan filter dengan 500 gr steel wool adsroben dan laju aliran biogas 3 lpm, menghasilkan peningkatan nilai kalor terendah yaitu sebesar 4.46%. Hasil eksperimen menunjukan peningkatan nilai kalor semakin tinggi jika laju aliran biogas makin rendah melalui kolom adsorben dengan massa steel wool yang semakin tinggi.

Abstract

The use of a fuel mixture of gasoline and ethanol can reduce the PM2.5 (Particulate Matter) value in the air by 0.3-0.4 µg m-3. This research aims to see the performance of a 4-stroke engine 113cc in standard conditions using a mixture of premium and ethanol. This research learns 5 types of mixture, E0, E10, E15, E20, and E25. The fuels was tested at 5 engine speed 4000, 4500, 5000, 5500, and 6000 rpm, at prony brake dynamometer to measuring performance, fuel consumption and Specific Fuel Consumption (SFC). The results of research show that the highest torque and power is the E15 mixture, that is 8.90 Nm at 5500 rpm and the power obtained is 5.529 kW at 6000 rpm. Meanwhile, the lowest fuel consumption value is found in the E10 with a value of 169.78 gr/hour at 4500 rpm. The lowest SFC value of all fuels is the E15 at 5000 rpm on 27.565 gr/kW.h. This is the lowest of any other fuel, because the Research Octane Number value is following the compression ratio of the engine, so there is no delay in ignition symptoms that occur during the combustion system. The viscosity value also contributes to the difference in data.

Abstract

Conventional cooling systems used in office buildings are one of the causes of ozone layer depletion and greenhouse effects. It requires the advancement of new technologies that are safe for the environment to be used in cooling systems in office buildings. Absorption cooling systems using solar thermal energy have many advantages by using non-destructive working fluids such as water, or in the form of saline solutions. This is a form of energy saving and safe for the environment. In order to obtain real and objective measurement data, testing is performed in two stages, namely the test equipment testing stage and the second stage is data collection when the test equipment is fully operational. The test equipment can be used in stand-alone systems or conventional air conditioners. In the test, it is known that the average percentage of solar thermal energy consumption per day is 40% of total energy so due to solar thermal energy consumption, the average COP value of this system per day is 2 and this value is greater than similar absorption cooling systems. conventional, then by knowing the value of solar energy consumption, can be seen the value of CO2 emissions reduction of 143.8 kg CO2 per day.

Abstract

This research is motivated by the increasing gas emissions produced by industrial, automotive and household activities which mostly use fossil energy as an energy source. CO2 capture is introduced to the use of gasification technology in an effort to reduce CO2 emissions which are one of the causes of the greenhouse effect. The role of microwave is also introduced as an effort to increase thermal efficiency and increase production and quality of syngas and its role in reducing tar which is known to be high in biomass gasification. The utilization of water vapor is also clearly disclosed and its effect on syngas products, especially hydrogen gas. The role of the parameters that affect the gasification process is analyzed to see which variant has the best role in improving the quality and quantity of syngas. Research development opportunities are presented by looking at research gaps and future prospects
