Thermoelectric cooler box was designed with the purpose of cooling with thermoelectric cooler (TEC) Peltier plate as a cooling medium. The objective of this project was to invent a cooler box that is suitable for outdoor activities. The thermal conductivity which is to measure the ability of the material to conduct heat in each layer inside the thermoelectric cooler box was identified for heat transfer analysis. Thermoelectric cooler box can be operated with a 12V battery or 12V DC power supply. The battery power can be charged using a 20W solar panel (if the battery power is drained out), with the condition that there should be heat radiation to generate electricity. Thus, no additional cost is needed on ice cubes whereby previously it requires more ice cubes to maintain the cold temperature inside the cooler box. By using a Peltier plate, the cooling hours inside can reach up to 100,000 hours with a maximum of 12 can of beverages stored inside the cooling box. Based on literature reviews, conduction and convection resistance between each layer of materials inside the cooler box play an important role to ensure heat is transferred inside the box. The heat sink also helps to ensure heat dissipation before flowing into the cooler box. In this design, a total of 56 kW of heat can be transferred from the box to keep the cooler box cool with the minimum temperature 15.6°C within a period of 35 minutes.

This study aims to create a prototype of an electronic key system using internet of things-based RFID with a validated monitoring system with registered data. This system is applied to the door of the Integrated Laboratory of the Department of Electrical Engineering, University of Lampung. The electronic keys that are created are very difficult to break into and also easy to change the access secret code to maintain confidentiality. The developed electronic door lock device has strong security reliability with code validation. The code validation block serves as a door unlock determinant. The validated data will produce a signal 1 which will drive the actuator, in this case the door lock solenoid, to work (lock open). The security code has 2554 combinations. To access the door from outside, the RFID tag should be registered in the database and permitted by administration and the ID number data is on the processor. The counter will count the number of people who pass through the door, if more than one person then the buzzer will sound. Then the door lock solenoid is closed and will lock the door again. From the experimental results it is found that this system can work well with a minimum delay of 1.8 s obtained at a distance between devices of 5 m.

Nowadays in Malaysia, the livestock industry has become the increasing demand over the past few years. Like agriculture, livestock is also a growing business that can help local farmers to generate their income. Thus, an economic and practical chopper machine for livestock feed is necessary to fulfil this demand. The machine is driven by an AC powered motor (1400 rpm, 1 Hp). It is divided into five major components, which are the fodder inlet, fodder outlet, power unit, cutting unit and frame stand. For safety reason, a cover made by clear acrylic Perspex were built in front of the blade to prevent any injuries. The machine structure is reasonable and practical as it is supported by four lockable wheels and handle for easy movement. Time taken to finish the chopping process will be analyzed for both methods. Three different weights of fodder will be used. For 500g, 1000g and 1500g of weight, average production time taken by machine is 15s, 33s and 42s respectively. While conventional method is 240s, 400s and 640s respectively. The percentage decrease of production time was calculated to evaluate the performance. Based on the result obtained, it shows that by using the chopper machine, it can help to reduce the production time to produce the chopped fodder compared to the conventional method. For weight 500g, it reduces the production time to 93.75%, for weight 1000g to 91.75% and lastly for weight 1500g to 93.44%. Hence, the chopper machine is practical, flexible and cost effective to use for chopping fodder.

The implementation of Patient Monitor (PM) in ICU, ICCU, PICU and NICU currently imposes a significantly high cost of investment. According to studies conducted, there are three main parameters required to be measured, which are heartrate (BPM), oxygen saturation (SPO2) and body temperature (T). These are highly needed by the medical personnel to monitor in order to determine patient’s vital state. The low-cost patient monitor prototype (named Patient Monitor 3 Parameters or PM3P) was developed using Arduino platform. In order to measure the parameters, two types of sensor modules were chosen, namely MAX30100 for gathering heartrate and oxygen saturation data and DS18B20 for gathering the body temperature data. The prototyping process also included fixation and finalization of electrical circuit on a printed circuit board (PCB). The PM3P underwent extensive validation process by comparing it to the real industrial PM made by healthcare equipment industry. The comparison was done over data gathered by both system that were conducting the same measurement runs in parallel. Results of validation indicates that the low-cost patient monitor prototype has a slight error of 0,31% for heartrate and 1,59% for oxygen saturation compared to the industrial one. Further improvements for the Arduino based PM3P are also proposed in this paper in order to enhance its reading accuracy, namely calibration.

The demand for poultry products is seen increasing from year to year. This is a good thing for local chicken entrepreneurs. But the task of plucking chicken feathers is time-consuming and tiring. The production of machines to help simplify the process of removing chicken feathers is seen as a necessity for these small and medium industrial entrepreneurs. This is why we focus on producing chicken feather retractor machines (CFRM) that are capable of processing up to five chickens at once. This machine is portable and easy to move around and supported by four wheels that can be locked to ensure stability. This machine can perform effectively to remove feathers using friction concept between the chicken and the plucker fingers rubber which attached around the drum. The machine also environmentally friendly by filtering the feather from scattered everywhere and only allow water to come out. The result shows that this machine operates under the motor powered with 115.13 rpm with the rotating plate area is 0.166 m2 and drum volume of 0.158 m3. This machine managed to remove the feathers of up to five chickens within 30 seconds to 60 seconds.
