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.

Radiotherapy is a treatment for cancer using high-energy radiation, usually X-rays. The type and amount of radiation received is calculated by oncologists and medical physicists to destroy cancer cells, these cells are abnormal cells. This stops the cancer cells from dividing properly and as a result the cancer cells are destroyed. This treatment is planned to protect healthy tissue as much as possible from radiation which has destructive properties, however some healthy tissue can be affected which will later cause side effects. Radiotherapy uses a Linear Accelerato (LINAC) device in its treatment. The LINAC can produce two beams, namely photons and electrons. Photon beams are usually used to illuminate tumors in deeper tissue in the body, for example breast cancer, cervical cancer and nasopharyngeal cancer, while electron beams are used for cancer therapy in surface tumors. The role of radiotherapy in the treatment of breast cancer has a long and controversial history. One of the first clinical trials ever conducted, it began in 1949, and remains the subject of new trials still being initiated today. Early trials clearly showed that radiotherapy reduced local recurrence, with a relative risk reduction now known to be approximately 70%, but a reduction in recurrence rates did not translate into a reduction in mortality. Theories explaining this difference are numerous, including the detrimental effects of radiotherapy on immune function.

Indonesia is expected to enter the Demographic Bonus era, a condition where the population of productive age is greater than that of non-productive age. This dominant generation of productive age can also be called the Millennial Generation. According to data held by BPS regarding the increase in Indonesia's population in 2015, the percentage of the working age population was around 70%. The Demographic Bonus has the potential to spur Indonesia's economic growth. However, this condition has requirements, namely the need to provide housing facilities that can accommodate the percentage of the working age population in the range of 70%. The Demographic Bonus has the potential to spur Indonesia's economic growth so that it is hoped that it can improve the welfare of the Indonesian people. However, this condition has requirements, namely the need to provide housing facilities that can accommodate these millennials. Moreover, the current urbanization trend is encouraging the millennial generation to work in big cities in Indonesia. Providing housing facilities in areas supported by adequate transportation facilities or transit/TOD-based housing development can increase the work productivity of millennials. However, the challenges faced in housing services in TOD areas are land issues and ownership status owned by private parties because strategic locations have higher value from an economic perspective. If this happens, then residences in TOD areas will become typical residences intended for people with high incomes. On the other hand, not all millennials are high-income people. In terms of age, most millennials are still in the middle and lower category because they are still at the stage of starting their careers, so providing housing facilities for millennials does not only pay attention to location, but also to economic aspects. In this article, we discuss affordable housing in TOD areas as fulfilling housing needs for millennials along with concepts from an architectural perspective that have been implemented in Indonesia and in several countries in the world as a comparison so that they can be input for special development of affordable housing in TOD areas for millennials in Indonesia.

Along with the development of the times, the need for electricity is very necessary. Electrical energy is one of the energy that is needed in using equipment that is related to electrical energy such as household, office and commercial industrial equipment that requires electrical energy. Bawean Island is one of the islands that requires a large amount of electricity due to the growing development of these sectors. With the rapid development of large-scale developments, the need for electricity needs to be increased in order to meet people's demands related to electricity needs. Technical losses are losses that occur for technical reasons where energy is reduced by turning into heat or heat energy. Basically technical losses occur based on energy losses in components caused by errors in the components themselves. Technical losses that occur in distribution transformers are common. In principle, losses always occur because efficiency cannot be 100%. Energy is lost along with distribution from upstream to downstream of distribution transformers. Based on the formulation of the problem taken, the researchers calculated losses at neutral currents, copper losses, total losses, output power and total losses in the form of prices. From the results of the conclusions above, it can be seen that the greater the current in the neutral of the transformer, the more losses that occur in the transformer.

Degenerative disease is a health condition of an organ or related tissue whose condition can deteriorate over time due to changes in body cells that affect organ function as a whole. The factor is due to unhealthy life changes such as lack of activity and frequent exposure to harmful substances into the body. Degenerative diseases include hypertension, diabetes, cholesterol, cancer, and death. Harmful substances or free radicals can be inhibited by antioxidants. One drug that has antioxidant activity is ascorbic acid (Vitamin C) which functions as an immune booster and is used by the public because it is effective as an antioxidant and health therapy but there are side effects in the form of gastrointestinal. The research aimed to find candidate drug ingredients from compounds contained in black pepper seeds (Piper nigrum L.) as in silico antioxidants. The methods used are molecular docking and molecular dynamics. The results showed BLH19 had better toxicity than the comparator drug and had hydrogen interactions that could be stabilized by the amino acid Gln139. The results of molecular dynamic calculations for BLH19 have an RMSD value of 1.5 Å with a ΔGTotal of -33.50 Kcal/mol. While the comparator drug has an RMSD value of 1.6 Å with ΔGTotal -3.39 Kcal/mol. The results showed that the affinity level of ascorbic acid compared to BLH19 for the 4RP9 receptor was predicted to be a candidate for a new antioxidant drug.

CV Dafista Mulia is a drinking water producer company located in Lamongan Regency. The problem that is often faced by companies is the amount of waste that occurs in the process of producing bottled drinking water. The most critical percentage of waste in the bottled water production process (AMDK) is waste overproduction with a weighting percentage of 25.4%; waste defet with a weighting percentage of 16.2%; waste inventory with a weighting percentage of 14.9%; waste unnecessary motion with a weighting percentage of 14.1%; waste transportation with a weighting percentage of 11.7%; waste waiting with a weighting percentage of 9%; and waste excess processing with a weighting percentage of 8.7%. The initial activity time before the repair was 466 minutes (7 Hours 46 Minutes) and after the repair was reduced to 416 minutes (6 Hours 51 Minutes). Based on the Failure Mode and Effect Analysis (FMEA), it is known that the root cause of the problem with the highest waste is Overproduction, namely production planning that is not quite right with a Risk Priority Number (RPN) score of 396. Recommendations for improvements that can be proposed are to carry out production planning using data - historical data that exists and is adjusted to balance the purchasing of raw materials with orders from consumers so that the results of the Overproduction can become a safety stock so that the Overproduction can function in the next consumer order.
