Economic Improvement

Villagers of Delo and Raekore have a traditional eucalyptus refining business by boiling the eucalyptus leaves for aromatic oils. Eucalyptus oil produced quite well, it's just a long distillation process that is 5 to 6 hours so it requires a lot of wood. While the availability of firewood in the forest is currently quite difficult, so people often cut down trees in the forest. So need to find a solution by changing the way of boiling by steam method and using charcoal  fuel made from coconut shell, because it has a higher calorific value than the shell is burned directly. Traditional refined eucalyptus oil products, ranging from 2 to 3 beer bottles   (1 bottle of beer = 350 ml) per day, so that through the activities of IbM can apply the appropriate technology products that is the installation of wood crude oil refinery by steam method and the using of briquette fuel. The steamed container produced has a volume of 160 liters while the charcoal briquette printing device is capable of printing 8 charcoal briquettes in one print. The using of refinery installations by steam method and charcoal charcoal fuel, can increase the production capacity of eucalyptus oil  to encourage economic improvement of Delo and Raekore villagers. The eucalyptus refining oil refinery has a production capacity of 4 to 5 bottles of beer (1 bottle of beer = 350 ml) per day and charcoal briquette presses have a production capacity of 8 charcoal briquettes.

Energy is an expensive basic need for human life, especially energy from fossils, such as crude oil, gas, and coal. In an oil refinery factory or electrical generator unit, where heat is most dominantly utilized, the boiler is used to generate steam. The main problem in a boiler is its uncompleted combustion process because of the incomplete ratio of air–fuel. This problem is caused by the addition of deposits or sealing inside and outside of the tube fire heater which will reduce the performance of fired heater. The objective of this research is to study the effect of steam flow variation on burner and tubing for increasing heat and temperature as well as the quality of steam. This research used a package boiler B&W series 1986 model which can be seen at an oil refinery factory or steam power electrical generator unit in Indonesia. This package boiler has 50kg/hours steam production capacity, qualified superheated steam, maximum pressure and temperature at 7kgs/cms2 and 700oC. Quantitatively, the achievable heat efficiency which corresponded to the temperature increase caused by the steam injection is 41.25% and the specific enthalpy is 12.07%.

Abstract Energy willow as a species with broad adaptation possibilities, large production capacity and a wide range of applications, takes a special place among the plants grown for energy production. In this work an analysis was conducted in respect of the usefulness of this type of wood from experimental plantations as a clean source of energy generated in the combustion process. The heat of combustion and net calorific value of dry matter of energy willow wood, including selected sorts and classes of thickness were determined. Energy willow has a natural ability to accumulate heavy metals which are oxidized during the combustion process or remain in the ash, and consequently repollute the environment. In order to determine the environmental impact the content of heavy metals was examined in energy willow wood and in the soil of the experimental plantation. Metal concentrations were determined by the Atomic Absorption Spectrometry method (AAS). Results of the tests confirmed a close relationship between the heat of combustion, calorific value and wood thickness as well as its location in the tree structure. Furthermore, very large differences were found in the content of heavy metals in the samples of both willow wood and soil. The levels of heavy metal content in the wood of energy willow determine the agricultural use of ashes produced during combustion.

Process Plants

Process plants are vulnerable to natural hazards and, in particular, to earthquakes. Nevertheless, the quantitative assessment of seismic risk of process plants is a complex task because available methodologies developed in the field of civil and nuclear engineering are not readily applicable to process plants, while technical standards and regulations do not establish any procedure for the overall seismic risk assessment of industrial process plants located in earthquake-prone areas. This paper details the results of a case study performing a seismic risk assessment of an Italian refinery having a 85,000 barrels per day production capacity, and a storage capacity of over 1,500,000 m3. The analysis has been carried out resorting to a novel quantitative methodology developed in the framework of a European Union research program (INDUSE 2 SAFETY). The method is able to systematically generate potential starting scenarios, deriving from simultaneous interactions of the earthquake with each separate equipment, and to account for propagation of effects between distinct equipment (i.e. Domino effects) keeping track of multiple simultaneous and possibly interacting chains of accidents. In the paper the methodology, already described elsewhere, is briefly resumed, and numerical results are presented showing relevant accident chains and expected economic loss, demonstrating the capabilities of the developed tool.

Production Practices

<p><em>Tempeh had been recognized worldwide as a superfood. In Pengkok Village, Kedawung Sub-district, Sragen Regency, there were several traditional tempeh producers which supply fresh tempeh around Kedawung Sub-district. Tempeh produced in this area was also used as raw material for brownies production. "BROWNIESTA" is a Small Medium Enterprise (SME) which produces brownies made from tempeh. The demand of tempeh brownies was high, but it was difficult for SME "BROWNIESTA" to fulfill the demand due to the lack number of ovens. In addition, packaging, labels and the quality of the products had been unstable due to limited understanding of Good Manufacturing Practices (GMP) concept in food production. This community service introduced appropriate technology for SME "BROWNIESTA" in the form of: 1) introduction of gas-fired ovens, 2) introduction of packaging and labels and 3) GMP training according to BPOM guidelines. Partners actively participated in providing materials for the introduced oven trials, providing materials and tools for evaluation of product sensory quality improvement and facilitating the implementation of GMP training. Based on the evaluation results, the sensory quality of brownies produced using the introduced oven had increased as indicated by its softer texture and smoother crust that is not caramelized. The product was also packaged properly with product information on the label attached to the packaging. Oven introduction also increased the production capacity up to 150%. SME “BROWNIESTA” implemented better food production practices after completing GMP training. Therefore, it could be concluded that the introduction of appropriate technology in SME "BROWNIESTA" increase the capacity and quality of the tempeh brownies products</em><em>.</em></p>

Hot-mix asphalt used in pavement layers is produced by asphalt plants. In Brazil, despite the fact that these industrial units produce greenhouse gases, no control or measurement protocol has yet been established. This study aims to quantify emissions in different asphalt plants, in terms of carbon dioxide equivalent (CO2eq) and energy consumption. Asphalt plants were selected according to their type (batch or drum mix); production capacity (80 to 340 t/h), and whether mobile or fixed. In each plant, emissions were quantified and the energy consumption spent on drying and heating aggregates in the dryer drum was evaluated. The fuels used in the drier drum such as low pour point (LPP) oil, liquefied petroleum gas (LPG), and natural gas (NG) were evaluated and compared. The methodology consisted of surveying the thermal power of the dryer drum specified on the suppliers' catalog to calculate the volume of fuel required per ton of asphalt mixture produced. Based on the criterion of the lower calorific value of each fuel, the volume of fuel used was calculated according to the production of the asphalt plants. Through the GHC protocol tool, the quantification of emissions of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) gases was obtained, and then transformed into CO2eq emissions. As a result, lower energy consumption was observed in the mobile batch plants and higher consumption in the mobile counterflow drum mix plants. On average, 27.69% less energy per ton of processed aggregate was needed compared to the mobile counterflow plants. The use of natural gas in the dryer drum and for all plant models was the least emissive fuel. The results showed that for the mobile batch type with a capacity of 140 t/h, the emission was 13.62 kg of CO2eq / t. On the other hand, with the mobile counterflow type with a capacity of 200 t/h, 13.64 kg of CO2eq/t was produced. Finally, with the fixed counterflow type with a production capacity of 240 t/h and 300 t/h, emissions of 13.67 kg of CO2eq/t were obtained. Through this study, the mobile batch plant with a capacity of 140 t/h using natural gas showed the least environmental impact. When natural gas was used, this model obtained energy consumption and emissions 54.5% lower than the mobile counterflow model with a capacity of 50 t/h which showed the worst environmental performance.
