Abstract Contemporary approaches to “non-market accounting” depend critically on methods of “monetization”, i.e. determining prices for goods outside the market. Monetization constitutes a case of economic measurement in a narrow sense that has not yet been analysed in the literature on measurement in economics. Monetization, I will argue, uses homo economicus – originally created as a model to explain existing prices – as a measuring device, one that generates new prices for goods that are not traded on markets. Homo economicus, though long contested in microeconomics, is thus enjoying a dubious revival in non-market accounting.

Abstract. Ground resistance is required for protection of electrical installations. The size of the earthing resistance value has an effect on the rapidly discharging of electrical energy. The value of grounding resistance that meets the requirements of an Electrical Installation has been determined and set by PUIL (General Requirements for Electrical Installation) 2000. Methods are performed based on circuit-designed trials and measurement results. The design of this digital ground resistance measurement is not separated from the basic circuit of current and voltage measurement, the achievement of the measurement of ground resistance is generated from the measurement of voltage and current (V / I). The test results of the tool can be seen that the measuring tool of digital grounding resistance that is designed to build this has a precision and accuracy is good enough that the average percentage error of 6.29%. This measuring instrument uses two voltage sources that is the voltage for the measuring instrument and the reference voltage that is supplied to each electrode. In the use of this measuring device must be careful because the reference voltage is high enough that it can create a shock voltage on the electrode if not installed properly.

Colorimeter is a color measuring device that is a tool that can distinguish colors based on the value of the output produced. In this study a colorimeter device was made using the OPT101 sensor, an analog sensor based light detector. OPT101 sensor has characteristics if the intensity of light received is getting brighter, the greater the sensor output value and vice versa. Because of the characteristics of the sensor like that, this sensor can be used as a measuring instrument to determine the concentration of a food coloring agent. This study aims to look at investigating the relationship between the concentration value of a dye solution to the OPT101 sensor response value contained in the colorimeter tool. The dyes used are red (metile red) and blue (brilliant blue) with 10 different variations of concentration, with a range of 0.01% -0.1%. After the measurement experiments were carried out on the sample, the results obtained were almost the same as the theory, namely the relationship between the concentration value was inversely proportional to the value of the sensor output. The inverse relationship means that the more concentrated a dye solution is, the more the light intensity penetrates the substance or dims. So that the OPT101 sensor detects a dimmer light source, the sensor output value gets smaller, because the relationship of the sensor output value is directly proportional to the intensity of the received light. Based on the measurements that have been made, the results of sensor response values are obtained for the red sample with a range of data from 276,698 decreasing to 240,762, while for the blue sample from the range 9,828 it decreases to 8.75. The value for the blue sample is much smaller because the blue sample is much thicker than the red sample.

This study aims to create an independent urine measuring instrument based on the internet of things (IoT). This study was to see the differences in uroflometric measurements using an independent urine measuring based IoT tool compared to uroflometry in the urology clinic. The sampling method used was consecutive sampling with a total of 32 respondents. Uroflometry measurements were carried out twice, first using an independent urine measuring device based on the IoT, secondly using the standard uroflometric peak flow rate examination in the urology clinic. The results of measuring the average amount of urine per second using an independent urine measuring device based on IoT 22.22 ml / second, the average peak flow rate using uroflometry in the urology clinic is 23.97 ml / second, this shows that an independent urine measuring instrument based on IoT is not significantly different from uroflometry in urology polyclinic with a p value of 0.411, which indicates Ho was accepted, meaning there was no difference between the mean amount of urine per second and the average peak flow rate using uroflometry in the urology clinic. This study therefore concludes that an independent urine measuring devise based on the IoT instrument is effective for measuring urine emission per second. Suggestion: Follow up on the patent and legality of measuring instruments   Keywords: independent urine measuring instrument, internet of things(IoT), uroflometry, urethral stricture

Blood glucose is a very important element in the human body, but if it is deficient or excessive, it can cause chronic disease that can lead to death. To prevent this, it is necessary to monitor cholesterol and blood glucose levels regularly, at this time the tool for measuring blood glucose levels is still an invasive method by taking a blood sample at the fingertip by injuring it. This study aims to develop a non-invasive blood glucose measuring device using a Photoacoustic Spectroscopy sensor in the range of values from a laser pulse source (λ = 650 nm) which can detect glucose signals in the blood. The method of developing this research is by designing a non-invasive measuring instrument and measuring blood glucose levels in male and female participants to create a linearity equation between blood glucose levels and the output voltage from the sensor, then mathematically obtained a polynominal equation to convert the voltage to values. blood glucose level. Validation of measuring instruments designed by comparing invasive measuring instruments as a reference, using the Clarke EGA to determine accuracy based on the classification of values of blood glucose and blood cholesterol levels based on reference. The results of the Clarke EGA analysis show that all measurement data is in Zone A so that the measuring instrument with a photoacoustic sensor can be accepted.
