Introduction: Noise is unwanted sound which comes from various working tools that can cause hearing loss on workers expressed in decibels (dB). The ambient noise value in the workplace is 85 dBA. Ambient temperature in the workplace that is too hot is dangerous for the health of individual workers because it can result in various mental and physical health disorders. Methods: This research was conducted at one of the Ship Production Companies in Indonesia in March to June 2018. This type of research was descriptive and the design of this study was cross-sectional. The variables of this research were technical control, administrative control, and PPE control. The purpose of this study was to describe the efforts of controlling one of the Ship Production Companies in Indonesia in controlling heat stress and noise. The data used were primary data and secondary data. Result: One of the Ship Production Companies in Indonesia still had high heat and noise pressure. Three control efforts have been made including administrative control, technical control, and the use of PPE. The results shown in terms of technical control still did not meet the requirements because not all technical efforts were made. Meanwhile, administrative control and PPE control have met the requirements. Conclusion: Among the three control efforts that have not met the requirements yet are technical licensing while those that have met the requirements are administrative control requirements and the use of PPE.Keywords: heat radiation, noise, ship production

Printed Circuit

Recently, the development of electronic devices, such as smartphones, has meant that printed circuit boards (PCBs) have become complex multi-layer ones to provide both multiple functions and be compact. Blind via holes (BVHs) connecting the layers of the multi-layer board are processed by using a CO2 laser. The many benefits of direct processing by CO2 laser include a lower disconnect of the hole position as a result of the base drilling process in the inner layer circuit pattern. Also, efficiently dissipating heat from components improves the quality of the product as digital home appliances are increasingly compact, lightweight, and thinner. Using PCBs raises the radiation performance by the addition of alumina filler at the insulated layer. However, adding alumina filler means that laser processing is difficult, processing efficiency is reduced, and debris on the surface around the drilled hole increases. We consider what causes the changes in the processing hole by changes in the alumina filler content on the basis of data on drilling phenomena gathered with a high-speed camera. We found that the insulating layer material didn’t effect the diameter of the drill hole per laser spot diameter. The cross-section processing is done in a cone initially, and the truncated cone is then processed. And, we found that the hole depth and processing overhang was reduced, and the amount of scattering increased with the amount of alumina content filler.

Recently, some studies have addressed the use of a folded substrate to realize stretchable electronic devices including stretchable thermoelectric generators (TEGs). However, the utilization of the folded substrate as a heat radiation fin has not been achieved. Herein, we have proposed the construction of a TEG with an origami-like folded structure substrate called an “origami-fin” that can achieve a high heat radiation performance and is also highly stretchable. The origami-fin increases the stretchability of the TEG by bending a non-stretchable material into a folded shape, and it also works as a heat radiator because of its large surface area compared to that of a flat structure. We evaluated the heat radiation performance of the origami-fin and the stability of the performance when it was stretched. The results demonstrate that the origami-fin works as a heat radiator and enhances the output of the TEG, while also exhibiting a high stretchability with only a slight output reduction.

The article discusses the design and construction of industrial facilities and civil buildings in hot and dry climate on the territory of The South of Russia. In the design of buildings in these areas must consider the flow of heat radiation from the Sun, especially in summer. When you create a comfortable environment in these regions the preference is for air conditioning and ventilation. To achieve comfort, it is important to reduce the number of Windows and skylights. To avoid overheating, it is necessary to have knowledge about the characteristics of building materials. Choice of construction material should be based on its thermal properties, and consequently on the time lag of the heat flux. Dense heavy materials such as clay, brick and stone, have a very high heat-storage capacity: heating and cooling occurs slowly, therefore, in hot climates they have a big advantage, providing coolness in the room. The income source of heat and heat loss, which is often ignored by designers, are also large areas of glazing in buildings. Widespread use of large areas of glazing in buildings for dry hot climate led to the development of different types of sun protection devices.
