Abstract

At the time of radiotherapy treatment in addition to cancerous tissue, normal tissue around the cancer will also be exposed to radiation doses, inappropriate radiation doses will cause normal tissue to potentially become new cancers called Organ at Risk (OARs). To minimize OARs by using a device made of soft tissue equivalent material that is placed over the surface of the skin called a bolus. The function of this material ensures an increase in surface dosage, this material is also flexible, easy to form, resistant to temperature changes. One of the materials that is easily formed, not easily deformed, flexible and durable is Alginate, because it is a natural hydrogel extracted from brown seaweed. Alginate that will be used in this research is alginate which is often used by dentists to print dentures. Alginate powder is formed by dough with distilled water, then printed in a mold measuring 11 x 11 cm with a thickness of 5, 7 and 9 mm. The characterization of this alginate gel includes electron density and an increase in surface dose percentage. Electron density is obtained by using CT-Scan to find out CT-Number which is then entered into the equation to obtain electron density, electron density from Alginate is obtained by 0.949 so Alginate can be said to be equivalent to breast tissue and fat tissue. Increasing the percentage of surface dose obtained by using the Linac device, obtained at 10 MeV energy Alginate thickness of 5 mm can increase by 0.50%, thickness of 7 mm can increase 9.97% and 9 mm can increase by 19.64%. At 12 MeV energy, 5 mm Alginate is able to increase 0.36%, 7 mm thickness increases by 6.46% and 9 mm thickness is able to increase by 15.03%. With this result Alginate is a soft tissue equivalent material and is able to increase the percentage of surface doses, so that alginate can be applied as a bolus for radiotherapy.  Keywords : Alginate, Electron Density, Percentage of Surface Doses.

Abstract

Hypothyroid or thyroid hormone deficiency is a state of hormone deficiency due to the thyroid gland not being able to produce sufficient amounts. This hypothyroid is a complication that often occurs in nephrotic syndrome, but often does not show clinical symptoms. Hypothyroid in nephrotic syndrome occurs due to the release of thyroid hormone and thyroxin-binding globulin (TBG) through urine which will reduce the concentration of free thyroid hormone and increase thyroid stimulating hormone (TSH). The purpose of writing this article is to find out how to manage hypothyroid in children with nephrotic syndrome. The method used in this paper is qualitative research with a "library research" approach, where researchers as "key instruments" read theories that are directly related to the topic of writing sourced from books, journals, proceedings and other documents (online and printed) and make it into research data which were analyzed descriptively. The results of this study suggest that the condition of hypothyroid in patients with nephrotic syndrome often does not show typical clinical symptoms. So suggestions for screening for thyroid function need to be considered. Thus it is known quickly if there is a hypothyroid condition and its possible complications, and can be normalized thyroid hormone concentration (FT 3, FT 4, TSH) by using TSH as a marker of succession replacement therapy. The conclusion is hypothyroid is a complication that can occur in nephrotic syndrome which can cause complications in the form of growth and development disorders and can increase the risk of death or mortality, so that management must be carried out which, thereby reducing mortality or mortality  Keywords : child, hypothyroid, nephrotic syndrome

Abstract

Water cooling occurs since the heat energy of water is transferred to the air. Water is placed in a thin transparant vessel can reduce the effects of heat transfer by radiation and conduction, so the most dominant heat transfer is convection. Newton's law of cooling states that the rate of cooling is directly proportional to the temperature difference between the object and room temperature. By knowing the value of constant cooling, the air convection coefficient can be calculated. This study using three different sizes of cups, each of which is filled with hot water. In each glass inserted temperature sensors that connected to the interface, recording the temperature every 60 seconds using pasco capstone 14.1. The resulting graph was analyzed by exponential regression, in order to find the value of constant cooling, from this value can be calculated the air convection coefficient. The research result shows air convection coefficient value of W/m2OC, that mean if there is an object that has an area of 1 m2 and 1OC higher than room temperature, the thermal energy of the object will be lost of 19.9 J for each second.   Keywords: Water cooling, heat transfer, air convection coefficient.
