Published: September 2019

Abstract
The EU building stock is relatively old with 40% of it built before 1960. In Albania the building sector accounts for 26, 9% of final energy consumption, offering high energy saving potentials due to the great number of old residential buildings. Intervention is not always possible and, in order to achieve significant environmental savings, the national action plans cannot rely only on the physical improvement of existing buildings. This paper proposes a probabilistic LCA and LCC evaluation model using MC simulation, for the prediction of intervention options in existing buildings. The potential environmental and economic impacts of three intervention options: standard, ambitious retrofitting and new construction during the whole life cycle of a building are analysed. A framework is defined, with the purpose of estimating the value of a building in a specific time during its life cycle. Comparing the generated values of potential environmental impacts and associating them with the changes on the buildings value enables the process of deciding upon the most desirable and/or agreed combination. The results of the SLED Study 2015 on Albanian building typology are used, while the new construction model is defined according to German EnEV2014 requirements. The GWP values from the LCA/LCC assessment of the intervention scenarios, done through the SBS tool of Fraunhofer IBP, are used to create a prediction model for future alternative solutions especially in early planning phase. Decision-making through this model can encourage a sustainability strategy for energy efficiency improvement in the building sector of Albania.

Published: September 2019

Abstract
Indonesia is an archipelagic country that has remote locations. In such areas, the price of diesel fuel might be very costly. Hence, it is very burdensome for the community because this type of fuel is needed by diesel engines to drive generator sets, agricultural and production purposes. The utilization of dual-fuel diesel-gas engine is expected as a solution to this problem. This experimental study was carried out to compare the performance and economic value of operating a small diesel engine both with B20 biodiesel fuel and B20-LPG dual-fuel, with a variation of engine operating parameters, namely engine speed, LPG fraction and engine throttle opening. The performance parameters observed were torque, power, brake specific fuel consumption and brake thermal efficiency. Experiments were carried out in the laboratory at throttle openings of 50% and 100% with an LPG fraction of 10% to 70%. It was found that the best performance of the dual-fuel engine occurred at the throttle opening of 100% and an LPG fraction of 70%. In this condition, there was a 20% reduction in BSFC maximum, and a maximum power increase of 12%, compared to a single-fuel engine. The BTE increased by 9%, and the engine torque increased by nearly 5%. It is concluded that the performance of the dual-fuel engine generally increases compared to the single file mode. Another exciting conclusion is that the use of dual-fuel B20-LPG engines reduces operating costs by up to 40%.

Abstract
The educational toy business is one of the businesses with a good prospect and is expected to continuously grow. The estimated spending of educational toys in Central Java is 757,257 units per year. However, the local manufacturers can only fulfil 27% of the total needs, while the rest are filled by other manufacturers from Daerah Istimewa Yogyakarta or even from China. This is due to the high selling price, so it is less competitive compared to other competitors—according to the Chairman of “Asosiasi Penggiat Mainan Edukatif dan Tradisional Indonesia”. This high selling price is affected by high manufacturing cost caused by waste in resources usage; or in other words, low efficiency. This paper aims to investigate the relative efficiency of manufacturers’ education toys by employing the data envelopment analysis approach. Results show that three manufacturers are categorized as inefficient. Recommendations would be given so that the manufacturers could improve their efficiencies.

Published: September 2019

Abstract
The idle and delay time in an industry is categorized as production waste that will cause problems such as production quantity below the target. In addition, the waste also leads to cost losses and eliminate opportunities for the industry to gain profit. The need of waste analysis to optimize the costs incurred due to the idle and delay time. Lean manufacturing approach can be used to minimize that production waste. Value stream mapping (VSM) is one of lean tools that can be used to identify all production activity for an industry. This study is conducted in a steel processing industry. The result shows that the dominant production waste is delay time. There are seven factors causing the main production waste, i.e. operation, mechanic, adjustment, electric, computer, instrument, and utility. These factors are the cause of production waste and production activities that do not add value to product. A maintenance improvement program is developed to reduce the production waste. Manufacturing cycle efficiency in actual condition is 68,08% while efficiency value in the future condition is 71,3% so from proposed improvement plan that can increase manufacturing cycle efficiency equal to 3,75%.
