The research method used was a qualitative experiment, starting with taking broken piston rings No. 2 and 3, cutting the piston rings and testing them with hardness tests and composition tests carried out at the Indonesian State Maritime Polytechnic and Undip Central Java Integrated Lab. From the results of this research, it can be concluded that the used broken ring number 3 has the highest hardness of 140.26 HB and the used ring number 2 is 131.50 HB, so it can be concluded that the piston ring that has been used and exposed to high heat causes an increase in hardness and causes it to break. The composition test results showed that the carbon content of the new ring no. 2 was the highest at 15.30% and that in the used ring no. 2 was 12.08% because the compression ring was in direct contact with the compression chamber or in contact with heat. For the used number 3 piston ring, the carbon content is 10.43 and the new one is 11.02 because it is positioned below the compression ring and is not in direct contact with heat. for the used ring no.2, the Silicon (Si) content is low, namely 2.15% compared to the new one, 2.75% because the nature of Silicium is that it is resistant to high temperatures and as a compression ring compared to ring no.3, fracture occurs because there are no Manganese or Phosphate elements. which is wear resistant, strong and elastic. The microstructure of piston ring No. 2 is broken and the new two piston rings are less dense and have rough gaps. The broken piston ring structure of No. 3 and the new one looks a bit gray and has high levels of graphite iron and carbon elements.

Fresh or rotten meat is a different matter. Damage to the meat will produce a distorted odor, mucus, discoloration in certain areas and an undesirable taste due to the formation of metabolism. The odor is described as fishy, ​​rotten, containing sulfur and like ammonia. In this research, the author discusses a system for identifying the condition of meat based on the odor that arises from meat in three states, namely odorless odor, fresh odor and rotten odor. Fresh odor is taken from meat odor that is within 1 (one) day after being cut and rotten odor is taken from meat odor that is on the 2nd day. In this study, the test sample meat was placed in a closed container at room temperature for 2 days. Data was taken for 2 days from meat odors of known type. The sensor array consists of eight sensors made of conducting polymer material. The polymer materials used are silicon DC-200, PEG-20M, 0V-101, 0V-17, DEGA, PEG-200, PEG-1540, and PEG-6000 mixed with Carbon black. A two-layer artificial neural net consisting of eight input nodes and three output neurons, was trained using the Kohonen algorithm with a training process that was completed in 4 iterations. From 20 tests, 10 times exposure to steam from fresh odor and 10 times exposure to steam from rotten odor, carried out alternately, it was found that the system failed twice. Thus, the system success percentage reached 95 percent.

Naturally, a mother hen incubates her eggs until they hatch completely. However, the success rate of natural hatching is low, and hatching can be completed with a maximum of 10 eggs. Chicken farming, more specifically the chicken egg hatching system, breeders usually use an incubator for the process of hatching chicken eggs. In the incubator, there is a lamp that has been provided which is used for the process of warming the eggs so that the eggs can hatch properly and of good quality with incandescent lamps. In general, the process of hatching eggs often encounters problems or obstacles. The obstacle that is often experienced when hatching chicken eggs is that the incubator only uses incandescent lights. Therefore, to avoid this problem, a microcontroller was designed to overcome this problem. This tool is a combination of a microcontroller with an Arduino-based temperature and humidity sensor. With this tool, after the eggs hatch, when the lights are off, the sensor can read the output in the form of the incubator temperature, which is detected by the Arduino serial display. Design methods and experimental methods were used in this research. Tool testing is divided into three types, namely temperature testing, humidity testing and egg load testing. The result of this research is an automatic egg incubator machine that uses Arduino. Several electronic components used in the incubator are Arduino,

Using a mask does not need to be marked on the patient's chest so that by using a thermoplastic mask the shift towards the target object is smaller during irradiation.

Heat transfer in diesel engines is known to affect engine efficiency and emissions. Increased heat transfer to the combustion chamber walls reduces the pressure in the cylinder and the average gas temperature, which reduces the work transferred to the piston per cycle. Therefore, the amount of heat transfer in an engine largely depends on the efficiency of the engine. Changes in gas temperature due to heat loss from the combustion chamber also affect the formation of pollutant emissions. Higher temperatures in the cylinder promote NOx emissions, while lower temperatures in the cylinder create Particulate matter in the exhaust. Engine heat transfer is important, so engine heat transfer results must be accurately estimated.

Used cooking oil is oil that has decomposed fatty acids at certain limits so that it becomes unfit for use. Used cooking oil is obtained from the process of cooking or heating food using oil repeatedly and at high temperatures. The behavior that is often carried out by the community is that after being used repeatedly, the used cooking oil will be immediately dumped into the ground, ditches, pipelines or waters. This can result in environmental pollution in the form of death of aquatic biota, organisms in the soil, closing soil pores, contaminating groundwater and even increasing COD and BOD in soil and water. This type of community service is classified as expert service, namely community service carried out by lecturers in accordance with their field of knowledge, in this case through training activities in the pursuit of waste cooking oil using practical methods. The results of this service increase knowledge of the physical characteristics of cooking oil damage, the dangers of repeated use of oil, knowledge of waste used cooking oil management, and increased knowledge of waste used cooking oil utilization
