Abstract
Thermal performances were performed as preliminary research on double pipe heat exchanger with low number of longitudinal groove. The objective of this work is to determine optimal heat transfer parameter especially logarithmic temperature difference (LMTD) as a time series function. The thermal analysis in this paper also provide total number of heat absorb in the cold fluid. The rectangular-longitudinal grooves were incised on outer surface of tube side with number of longitudinal grooves of 2. The grooves high and width were kept constant at 0.3 mm and 1 mm respectively. The tube made of aluminium with outer diameter is 20 mm. The shell is made of acrylic which has 26 mm in internal diameter. Water is used as the working fluid with counter flow scheme. The volume flowrate of cold fluid was varied from 18x10^-5 m^ 3/s up to 25x10^-5 m^ 3/s which are equal to Reynold number (Re) around 31981 to 43610. The volume flowrate of hot fluid remains constant at 25x10^-5 m^ 3/s which is equal to (Re) around 30904. The LMTD of 2 grooves double pipe heat exchanger was better compared to that of the smooth one since the thermal sectional area are increased which essentially cause larger heat transfer.

Abstract
Cooling machines have a direct contribution to environmental damage including depletion of ozone layer and global warming caused by the leakage and discharge of synthetic refrigerants (HCFC and HFC) into environment. The discharge of refrigerant into the environment is 60 percent of service sector. Some obstacles found when making a model of a refrigerant waste treatment system since it could only be used for CFC (R-12)/R-134a refrigerants. This research aims at redesigning a machine made beforehand thus it can process various refrigerant wastes used in hospitality industries which involved several components such as compressors, oil separators, filters and distillers for recycling R410A refrigerants. By having this ability, all refrigerant waste can be recycled. Result shows that the redesigned machine can recycle refrigerant waste and the signal can be reused. Calculation results on COP cooling system using pure R 410A showed 4.5, whereas by using recycled R 410A refrigerant 4.3 was obtained. COP using recycled refrigerants was lower than the one using pure refrigerants due to contamination of dirt, oil and other elements. However, with COP value of 4.3 the system performance is still good, therefore the recycled R410A refrigerant can be reused.

Abstract
The high crime rate of motor vehicle theft in urban areas requires additional safety systems installed in our vehicles. The following paper presents an embedded system for vehicle safety. A simple safety with double layer activation ensures the vehicle cannot be turned on by a burglar even though it has damaged the ignition. Utilizing a combination of the drive by touching module and the arduino uno microcontroller, the security system works automatically when the ignition is off. To activate the vehicle, it requires activation of the touch of the hand at a secret point, so that the CKP signal will be sent to the vehicle ECU. At the same time, touch activation continues the 7V voltage as a power microcontroller. Next it is necessary to pair the Bluetooth signal HC-05 module with the vehicle owner’s cellphone using the boarduino application. Commands from the cell phone in the form of signals received by the Bluetooth module, will be forwarded to the control unit to activate the actuator so that the vehicle can be turned on. The safety system that was proposed after being designed, built, and tested gave good results as expected.

Abstract
Freezer cooler (CF) is one of the cooling equipment for the storage needs of frozen food at low temperatures. CF is an indispensable tool for storing food and drinks to be durable. So, it is safe for consumption. Ice cream products, for example, are susceptible to temperature variations and are easily damaged during storage. Temperature fluctuations can cause dramatic adverse effects on the quality of frozen food, ice re-crystallization temperature in ice cream, and this can create substantial economic losses, and degrade the quality of frozen food. Maintaining a stable temperature in frozen food storage is very important. Current CF cooling technology consumes large amounts of electricity. It is essential to develop research on CF cooling engines that are energy efficient and environmentally friendly. Current technology makes it possible to add PCM to the walls of the cooling machine. During the phase change process, the temperature remains constant, and a large amount of energy can be stored or released. Refrigeration technology testing with PCM integrated on the evaporator has been carried out in this study and can reduce energy consumption by 4 percentage, increase COP by 6 percentage.
