Abstract

Osteoporosis or bone loss is a chronic disease characterized by low bone mass accompanied by changes in micro-architecture of the bone and a decrease in the quality of bone tissue that can cause bone fragility, so that bones are easily cracked or even fractured. Osteoporosis is diagnosed by measuring bone mineral density using DXA (dual-energy X-rayabsorptiometry). Treatment with device this expensive and not widely available. So it is necessary to find an alternative method of detecting a cheap one. This study aims as an initial study to find an alternative way of early detection of osteoporosis by looking for the texture characteristics of the human bone. Sample in This study took 19 people with inclusion criteria including postmenopausal women who declared healthy, not broken bone and has no skeletal abnormalities since birth. Sample measured density mineral bone(BMD) or the degree of osteoporosis with DXA. Then an X-ray is done to get bone image. The stages of the research are: 1) preprocessing X-ray image of the human bone; 2) determine the value of the texture of the human bone image with gray level method co-occurrence matrix 3) test connection between the value of the human bone texture image with BMD lumbar spine. The results of the correlation test show that there is correlation between the value of human bone texture and BMD of the lumbar spine to characterize variance and significantly statistics (P0.05).

Abstract

Phototherapy is a technology used for therapy in infants who suffer from hyperbilirubinemia or jaundice, this disease is due to the accumulation of bilirubin in the blood which is marked by the skin or the whites of the eyes turning yellow, babies who suffer from this disease are usually called yellow babies or icterus. This Phototherapy tool works by giving a blue light to the baby's skin directly for a certain period of time (depending on the level of bilirubin in the baby). The baby will be exposed to blue light which has a wavelength in the range of 450-490 nm for a certain period of time until the level of bilirubin in the baby's body drops to a safe level. With the advancement of technology, we want to add a little innovation by applying the use of a microcontroller to the phototherapy tool, in this case we add the time and temperature sensor DS18B20 as an indicator that will be displayed on the LCD screen so that it can make it easier for the user to turn off the tool and automatically and can notify the temperature of the baby who is getting sick. is doing this blue light therapy. In this case the time can be set according to user needs. From this research, it was concluded that phototherapy tools can be used to treat bilirubin babies. Advantages of this tool that users can monitor the baby's temperature and turn off the device automatically because we added a temperature sensor and timer to the phototherapy tools

Abstract

Biodiesel is a very potential material used as a substitute for diesel fuel derived from petroleum. In manufacture of biodiesel was used waste cooking oil with FFA levels obtained which is 3.1%, so that the transesterification process is directly carried out. This study aims to find out the physical characteristics of biodiesel produced from waste cooking oil with a molar ratio of waste cooking oil to methanol 5:1 and 4:1. Method that used in this research is experiment and analytic of physical characteristics of biodiesel products made from used cooking oil. The results of the physical characteristic test of biodiesel with a ratio of 5:1 and 4:1 showed that the biodiesel density of waste cooking oil had met SNI 04-7182-2012. Viscosity test results showed that biodiesel from waste cooking oil has not met SNI 04-7182-2012. The results of flash point tests showed that biodiesel from waste cooking oil has not met SNI 04-7182-2012. Freezing point test results showed that biodiesel from waste cooking oil had met SNI 04-7182-2012. The results of the heat value test showed that biodiesel from waste cooking oil has not met SNI 04-7182-2012. And the yield shows that biodiesel from waste cooking oil has not produced a significant biodiesel yield.

Abstract

This study aims to analyze the effect of the type of electrode in the electrolysis of seawater for the production of hydrogen gas. The methods used include two types of electrodes, namely copper and aluminum and also design tools for electrolysis of seawater. Data collection is carried out every 20 minutes, the electrolysis process takes place at a constant voltage of 12 volts. The results obtained showed that the copper electrode produced 732 ml of hydrogen gas and a lifetime of 820 minutes with an average rate of 0.893 ml/minute and the highest hydrogen yield of 3.83% at 400 to 440 minutes while the aluminum electrode produced 693 ml of hydrogen gas. and a lifetime of 680 minutes with an average rate of 1.019 ml/minute and the highest hydrogen yield of 5.92% at 120 minutes.

Abstract

Indonesia is an archipelago, so many settlements close to the beach or sea. People living in the area are still many who lack clean water. One way to get clean water is sea water by distillation. Distillation is a liquid changes into steam and the steam is cooled back into a liquid. The process of designing and manufacturing distillation in this paper serves to make sea water into fresh water and also to stabilize the temperature during heating. Given these problems required temperature control system. Application of fuzzy logic controllers are expected to solve the problem of temperature stability in sea water distillation equipment. The sensor used is LM 35 sensors as readers seawater temperature is used as a reference to maintain a temperature in the range of 80° -100°C. Fuzzy logic rules are applied has a 9, which is obtained from the membership functions of 3 error and 3 delta error membership functions. Application of Fuzzy Logic Controller When the set point temperature of 85°C temperature response curve is obtained which has a performance controller Error Steady-state = 0.35%, Max Overshoot = 0, settling time = 103 minutes, peak time = 0, rise time = 37 minutes. With the set point of 75°C -99°C then obtained a qualified water quality water temperature of 100°C is worth to drink and has a good time efficiency for distillation temperature.
