Abstract

Nowadays, Energy comsumption in the world tend to depend on fossil fuels. Alternative energy is still less developed. Indonesia has potential to develop alternative energy, especially biomass. One of this biomass is dried leaf that can be done to be briquettes. Dried leaf briquettes can be as an alternative fuel may be a solution for energy crisis. Economically that briquetting of the dried leaf could be a very promising business. Briquetting of dry leaf can be done with the simplest of techniques. It’s necessary doing techno economic analysis of charcoal briquettes of dried leaf. This research was done by using two types of adhesives briquettes  namely tapioca flour and sago with a weight percentage of 30% by weight of dry leaf briquette. The result of this research is the best briquette adhesive is tapioca flour because it produces water content of 25%, ash content of 13.85%, carbon content 61.15% and calorific value is 7100.23 calories. If this compare with adhesive sago are the water content is 23.08%, ash content of 10.5%, carbon content 69.41% and calorific value is 6325.66 calories. When compared with the comparative quality of briquettes SNI no.1 / 6235/200, only the carbon content of which has not reached for both types of the adhesive. The results of the calculation of the cost of production, to produce briquettes with a capacity of 15,000 kg of briquettes per year is Rp 42,312,600.00 while the cost of production Rp 2820.00/kg and selling price that can be offered to consumers are Rp 4,300/Kg. In this economic calculation values obtained BEP (kg) is 15008.75 kg and BEP in rupiah at Rp 42,324,675.00. While its payback period is for 90 days.

Abstract

The energy demand of the world is foreseen to be increased due to improvements on the living standard of developing countries and the development of global economy. The increase in sustainability of energy supply must be considered as a must to avoid spoiling natural resources for the next human generations and more dramatic effects such as global atmospheric warming. The utilization of CO2-free energy sources, as renewable energy, is one of the most promising way. Nevertheless, massive energy production with such energy sources are far from being practically feasible in short-medium term and an innovative solution should be put implemented CO2. This general assumption is also applicable to any energy carrier such as hydrogen or electricity. In this paper, analysis of the hydrogen production processes conducted and the discussion of the need to develop a CO2- free production scheme like methane cracking is shown

Abstract

Coronary artery disease (CAD) is a disease that most cause mortality in Indonesia. CAD is caused by cholesterol-containing deposit (plaque) that make the coronary artery become narrow and can cause a heart attack. Stent implantation is the most common treatment to opens or alleviates the narrowing coronary artery. A preliminary study has done to simulate the expansion of coronary stent with negligible balloon method. The negligible balloon is less accurate and far from realistic condition because it neglects the presence of the balloon. This study has proposed another method to simulate the stent expansion. Hyper-elastic balloon method is used to investigate the stress distribution, outer diameter change, and dogboning phenomena of the stent.

Abstract

Global warming caused by greenhouse gas emissions, e.g. carbon dioxide (CO2), in the atmosphere is now becoming a very serious problem facing the world community. Carbon dioxide emission increase from year to year, thus a necessary effort to reduce CO2 is required. Amine-based absorption is one of the methods for post-combustion capture. Monoethanolamine (MEA) is commonly used for CO2 capture solvent. This study aims to measure protonation constant (pKa) of MEA from 30 to 60°C using the potentiometric titration method. The results show that the pKa values of MEA are in general agree with the literature data. For instance, the pKa value of MEA at 30°C is 9.83 and that obtained from the literature is 9.80. Comparison between those two values gives a deviation of 0.22%.
