Abstract

Gasification of biomass can be used to produce fuel gas that could potentially be used as a powersource for the sustainable development. The main aim of this study is to determine the effect of lignin,cellulose, proximate and ultimate of ramie wood chip biomass and shell coffee to produce gas and thepotential for regional electricity generated. Research carried out by the analysis of lignin and cellulose,proximate and ultimate, calorific value, gasification, composition gases and energy potential. From theresearch results, the waste of coffee shells and ramie wood chips were used as a new energy source toproduce syngas by means of the gasification process. The highest lignin content was for 45.10% coffeeshell and the lowest for flax wood chips was 18.26. Meanwhile, the highest cellulose content was hempwood chips 44.82% and the lowest was coffee skin shell 17.93%. The potential energy produced fromgasified gas provides a correlation with levels of lignin and cellulose.

Abstract

Economists argue that the growth of GDP per capita in a country is greatly influenced by the growth inelectricity consumption in that country. The meaning of this statement is that if you want to increaseGDP per capita, the important thing that needs to be done is to increase the electricity supply capacity.Empirical data shows that every 1 kWh (kilowatt-hour) of electricity consumption contributes about $ 4 -$ 5 to GDP. Another study also states that every 1000 MW of installed capacity will contribute to a GDPof around $ 16 billion or equivalent to Rp. 200 trillion. Therefore, if Indonesia wants to become a countrywith the fifth-largest economy in the world with a GDP of $ 5.420 trillion in 2030, then one way that canbe taken is to increase the capacity of electricity resources to a minimum of 120,000 MW in 2025(RUEN, 2017). This background underlies the analysis of the relationship between the growth of theelectricity sector and the growth of the national economy. The analysis method that will be used is theanalysis of the economic impact with the Input-Output (I-O) method. Furthermore, the I-O table usedfor analysis is the 2014 creative economy I-O table. Based on the results of the study analysis, it isstated that the sub-sector that has high leverage is the sub-sector for electricity supply. However, tohave an impact on the national economy caused by the growth of the electricity sector, it is alsonecessary to develop the five sub-sectors holistically. The results of this study are expected to provideinput for stakeholders in formulating policies for the development of the electricity sector as an effort toachieve the target of advanced Indonesia in 2030.

Abstract

The development of technology for the use of natural resources as fuel is increasing. One of them is theresearch of third generation biodisel. This technology utilizes microalgae as an environmentallyfriendly raw material which is also a renewable energy source for oil. Biodiesel from microalgaeespecially Spirulina sp. is one of the energy sources that can replace conventional diesel fuel whichhas potential for high lipid content. This study aims to develop a microalgae cultivation technology in anairlift photobioreactor by adjusting the light intensity of the LED lamp to obtain an optimal growth rateand increase the biomass production of Spirulina sp. The research was conducted on an intermediatescale using an airlift type photobioreactor with varying light intensity, namely 1600 lux, 2200 lux, and3200 lux. Each treatment was carried out three times for 14 days. Measurement of biomass weight wascalculated using the gravimetric method, by taking samples every 7 days. Based on the data obtained,the application of different light intensities to the spirulina sp. cultivation system will have an effect onthe final result in harvesting day 14th, specifically the weight of the biomass produced. The averageyield of biomass on day 14th with the best results was obtained at light intensity of 1600 as much as 623mg / 100 ml.

Abstract

Conversion processes that involve large amounts of energy include processes in furnace reformers inthe steel industry. The reformer unit used to convert the process gas, namely a mixture of gas andsteam into CO and H2 gas with the help of a nickel catalyst. The heat energy used in the process is theresult of combustion from natural gas using combustion located above the furnace. The most importantthing in the conversion process is the radiative heat transfer in the combustion chamber to the reactionpipe wall so that enough energy is obtained to carry out the conversion process. One way to determinethe heat distribution of the reformer combustion chamber is to know the temperature profile along thereaction pipe, including the pipe wall temperature, the process gas temperature, and the temperatureof the combustion gas used as energy for the process in the reformer furnace. The performanceevaluation of the reformer furnace uses a mathematical model for combustion in the furnace which canlater be developed by knowing the fitting composition of the conversion results. The type of reformerstudied is the top-fired reformer. The results of modeling using data from the steel industry obtained thehighest temperature from the combustion of gas from the burner which is in the reaction pipe at aposition 3-4 meters from the upper end of the reformer around 1300 oC and the temperature of naturalgas-steam in the pipe reaches 860 oC at the end of the pipe. reaction. The pipe wall heating with naturalo ogas fuels provides a maximum temperature ranging from 890 C - 895 C on the outer wall of thereaction pipe, and the pressure inside the reaction pipe ranges from 8.0-8.5 atm.

Abstract

Indonesia has various types of energy sources, either from conventional energy sources or from newand renewable energy sources. Currently, Indonesia has a program to construct of 35 GW of coal-firedpower plant, as well as an intensive development of Geothermal power plant, since it's reserve isabundant. The construction of these types of power plants has a potency to increase Green House Gas(GHG) production, and therefore it necessarily needs to be anticipated. In 2018, there was 543 millionton of CO2 produced in Indonesia and about a half sourced from power generation sectors. Referring tothe ratio of 1 to 1.5 of CO2 converted with the process of hydrogenation, this indicates a promisingamount of methanol can be obtained. However, there are some challenges need to be overcome toachieve this beneficiary. This paper encloses a description of each challenge, with the main descriptionis on the potency of implementation in Indonesia. Some models from existing development aredescribed, to identify the process of development. This information can be used as a consideration forthe implementation in Indonesia.Keywords: CO2 utilization, Metanol formation, Hydrogen, Green House Gas, Geothermal power plant,Gas power plant

Abstract

Indonesia is the largest palm oil producer in the world. In the process of its processing into Crude PalmOil (CPO), the palm oil processing industry produces various types of waste, including liquid wasteknown as Palm Oil Mill Effluent (POME). POME contains organic matter that is high enough so it mustbe processed before being discarded into the environment. During this time, POME is treated usinganaerobic ponds which are quite large and produce metana gas. Metanae gas has a high level ofemissions, but it potential to become an energy source if it is utilized. Therefore, BPPT in collaborationwith PT. Perkebunan Nusantara 5 built a biogas production pilot plant from POME equivalent to 700kWfor boiler fuel at PKS Sei Pagar, Kampar Regency, Riau Province. The process of converting POMEinto biogas uses Continuous Stirred Tank Reactor (CSTR) technology. The research aims to choosethe best roof tank design for CSTR. The method used is the Pahl and Beitz method and the House ofQuality. The result of the study are the best specification planning data, which is 1400 mm in diameterand the construction site position at a height of 15350 mm from the bottom of the reactor, with use aninternal support column, with the best variant chosen is the fixed roof type with dome shape.

Abstract

Governmental policies that promote biofuels such as biodiesel have led to the generation a largeamounts of glycerol waste as a low-cost raw material. The purpose of this paper is to present a technoeconomic study on the production of biomass-based propylene glycol via glycerol hydrogenolysis,considering hydrogen feeds that partially or fully utilize renewable sources. For analysis andcalculation, computer simulations are carried out using the Aspen Hysys V11 simulator. The technoeconomic analysis is performed by modelling the propylene glycol synthesis process from glycerol,which is then used to calculate the facility capital cost and estimate operating costs to obtain an annualreturn on investment. Sensitivity analysis is also conducted for several parameters on a 36,000ton/year propylene glycol plant. The results showed the production cost was 0.76 USD/kg or 10,802IDR/kg when the hydrogen is generated from the natural gas steam-methane reforming (SMR)process. If the hydrogen is produced from the glycerol steam reforming process, which is fullyrenewable, the plant is not feasible, as indicated by a negative net present value (NPV).
