Fuel and chemical cargo are essential tools for national security. There is the potential for fire and environmental pollution when occurring an accident such as a collision or overturning. On the other hand, cases of cargo theft are also reported frequently. Currently, preventive efforts are carried out by attaching warnings to the vehicle body with stickers, but it is a passive method. Therefore, this article presents a design and application for monitoring vehicles in real-time with Electronic Tracking Control Systems (ETCS). If the vehicle speed is more than 60 km/hour, ETCS will send an SMS to the vehicle owner about the speed and location of the vehicle being monitored. With ETCS, vehicle accidents and misuse can be minimized by quick monitoring and communication between the owner and the driver.

The use of nanoparticle coolant fluid in the car radiator increases the rate of heat transfer and facilitates the reduction of the overall radiator size. In this study, heat transfer characteristics of tri-hybrid nanofluids-based water/EG (60:40) were analyzed experimental and compared with water/EG (60:40). Four different nanofluids concentrations were prepared by adding 0.05 to 0.3 vol.% of tri-hybrid nanofluids dispersed a mixture of water/ethylene glycol (60:40). Experiments were carried out by varying the flow rate of coolant between 2 to 12 LPM for working temperature of 70 °C, the velocity of airflow remained at an average of 4 m/s, to understand the effect of coolant flow rate on heat transfer. The results showed that the thermal performance of tri-hybrid nanofluids in a water/EG (60:40) mixture has been investigated for volume concentrations of up to 0.3% and working temperature of 70 °C. The maximum enhancement of heat transfer coefficient for air side is observed up to 23.8% at 0.05% volume concentration meanwhile for coolant side is observed at 39.7% at 0.3% volume concentration. The pressure drop and pumping power have the same pattern which increasing in volume concentrations.

The performance of an automotive air-conditioning (AAC) system is influenced by a variety of operating conditions. This can be addressed by employing optimization techniques that can suggest the appropriate parameters for the best results. In this study, the optimum operating conditions for a composite nanolubricants-fuelled AAC system were investigate using Taguchi's design of experiment approach and analysis of variance (ANOVA). The motor speed value, initial refrigerant charge, and composite nanolubricants composition ratio were chosen as operating parameters to investigate the AAC system performance, focusing on the coefficient of performance (COP) and compressor work. Orthogonal arrays (ORs) L25 (56) was selected to determine the optimum operating parameters of the AAC system. The optimum values for speed, refrigerant mass, and composition ratio were determined to be A4B1C5 (60:40, 900 rpm and 155 g), respectively. The motor speed was the significant factor influencing both COP and compressor performance by 78.13% and 89.29%. A confirmation test was conducted with the optimum levels of AAC system parameters to verify the efficiency of the Taguchi optimization method. The validation between the optimization results and the experimental results yielded a maximum error of 9.85%, indicating that the findings of this investigation were acceptable.

Some of the damage that occurs in the structure and construction of engine elements that experience dynamic loading at the time of operation is caused by fatigue (fatigue), which occurs without beginning signs so that it causes great damage and loss. Fatigue strength is the process of local changes in the structure that occur permanently in accordance with the period of time caused by conditions where stress or strain occurs which results in cracks or fractures after being subjected to repetitive loads. Surface roughness factors that affect fatigue are applied in the analysis and application of machining, which are finely grinded and rough machined. Analysis was carried out on 6063-TF aluminum alloy material which is widely used for motor vehicles. To find out the effect of the above, the fatigue strength test is carried out with a Rotary Bending Fatique Test to obtain a cycle value or fatigue age and certain neighbors so that it can make a semi-log S-N diagram with statistical calculations.

Along with the times, every human level and life will be upgraded automatically. Likewise, the company if it does not adjust to the times, it will be difficult to adjust. As with the production process, there will be differences from time to time. From time immemorial, doing work manually, and in the present era using technological tools. Lifting the car seat manually makes the operator complain of pain, due to the high production volume. To eliminate the complaints from these operators, a proposed tool design was made. The method used is Axiomatic House of Quality. In general, Axiomatic Design can help the product development process be more structured with a focus on design that fits the function of the product. The first step in this research is to collect input from customers. Then after getting input from the customer, it is converted into a customer attribute. Then, develop the concept by making several alternatives based on the combination table. Next, determine the design that will be used and carry out testing and coordinate with the user, namely the assembly operator. Finally, determine the specifications and final design of the tool for lifting a seat whose load exceeds the lifting standard. The results of this study are in the form of a design tool for lifting the seat which is expected to reduce complaints of pain to the operator. So that this design design makes the company a consideration for implementation.
