AbstractThe paper analyses the role of control and monitoring of electro-energetic equipment in order to reduce operational costs, increase profits and reduce carbon emissions. The role of SCADA and EcoStruxure Power systems is presented and analysed taking into account the energy consumption and its savings. The paper presents practical and modern solutions to reduce energy consumption by up to 53%, mass by up to 47% and increase the life of the equipment by adjusting the electrical parameters. The Integrated Navigation System has allowed an automatic control and an efficient management. For ships, the implementation of an energy efficiency design index and new technologies was required for the GREEN SHIP project.

Transesterification Method

In this study, production of biodiesel from new and used palm and soybean oils was carried out using a transesterification method. The effect of catalyst amount used towards the percentage yield, soap content and heat of combustion of the biodiesel produced was investigated. The soap content and heat combustion of the biodiesel were determined using titration (AOCS Cc-95) and heat calorimeter bomb (ASTM D240-09), respectively. The results showed that catalyst concentration of 0.5 w/w% gave the best result in terms of yield of biodiesel produced from both palm and soybean oils. However, the quality of biodiesel (i.e. soap content and heat of combustion) produced from palm and soybean oils behaved differently towards catalyst concentration. Overall, both oils (palm and soybean), either new or used oil apparently showed no significant difference in term of yield or qualities of biodiesel produced. This indicates that the used oil has high potential as an economical and practical future source of biodiesel.

Treatment Parameter

Acid treatment is one of the cheapest techniques and least applicable processes in the recycling of used lubricating oils. In this work, the performance of sulphuric acid in the treatment used oil was studied. The effects of the critical treatment parameters (acid volume, concentration of the acid, treatment temperature, stirring time and treatment time) were investigated by varying one treatment parameter at a time and analysing metal content in the sample of the treated oil using atomic absorption spectrometry (ASS). Thereafter, an optimal solution was determined by the combination of the optimum values of each treatment parameters. The original conventional treatment parameter values, resulted in 13.2 ppm and thereafter was optimised to 11 ppm this showed a definite improvement in efficiency. This result is also comparable to other data obtained in previously studied work which employed the same conventional treatment parameters. The optimal solution is within 10% variation as compared the standard individual metal content which ranges 0-10 ppm.

Long Time

The author's research is that first, the practice of buying and selling oil that has been used before has occurred in Nagari Saruaso, Tanjung Emas sub-district, has been going on for a long time, that used oil from consumers is not used anymore or is no longer needed by consumers, so the used oil is left in the workshop. then the motorcycle repair shop collects used oil in a container or drum. The used oil is resold by the workshop to used oil collectors. Second, from the Sharia Economic Law review that the activity of buying and selling used oil at a motorcycle repair shop in Jorong Saruaso Barat, Nagari Saruaso is declared invalid, because the owner of the workshop is not the legal owner of the used oil, but it can be legal if there are pillars of buying and selling, namely ijab (an expression of buying from a buyer) and qabul (an expression of selling and selling).

Percentage Conversion

In this study, production of biodiesel from waste cooking oil (WCO) was carried out via ultrasonic-assisted transesterification method. Calcium oxide (CaO) was used as a catalyst. The effects of methanol to oil molar ratio, reaction temperature and the catalyst amount towards the percentage conversion of oil to biodiesel were investigated. The biodiesel produced was analyzed using GC-FID method. The results obtained showed that 82 % of oil was successfully converted into biodiesel. This indicates that the used oil (WCO) has the potential to be the future source of biodiesel. Catalyst concentration of 3 w/w%, methanol to oil molar ratio of 15:1 and temperature of 65°C are the best condition for the conversion of oil to biodiesel. The result obtained was found out that, methanol to oil molar ratio and catalyst amount has given significant effect on the conversion of oil. However, temperature ranged from (35 to 75) °C apparently, showed no significant effect on percentage conversion of oil.
