Cotton candy is one of Indonesia's traditional foods which was quite popular in its time. Cotton candy is made from sugar that is given food coloring, cotton candy is made using a special tool that rotates and produces refined sugar fibers. Most cotton candy consists of air cotton candy feels sweet and sticky. Even though it looks like wool yarn ... The design of this cotton candy maker uses an arduino uno microcontroller, equipped with a temperature sensor, 3 push buttons and a heating stove as a heating container for the sugar container design of this tool. All Arduino Uno microcontroller working systems have been programmed using the C program language on the Arduino Uno microcontroller. Using a dose of 1/2 spoonful sugar, the average initial temperature (54.5 ° C) and the average final temperature (64.8 ° C) were obtained. Measuring one (1) spoonful of sugar, the initial heating temperature with an average (68.8oC) average final temperature (74.2oC). The dose of sugar 1 1/2 spoon, the initial temperature of the heater with an average (70.4 ° C) the average temperature of the final heater (77.4). This tool takes time to heat the heating stove in approximately 2 minutes to reach ambient temperature (54oC). Testing to find out the exact time of each dose of sugar. as in the dose of half a sugar (1/2) a spoon an average of about 120 seconds is obtained, a dose of sugar (one) spoon is obtained an average time of about 150 seconds and in a sugar one and a half (1½) spoon an average time is obtained about 180 seconds. ABSTRAK:Permen kapas adalah salah satu makanan tradisional khas Indonesia yang cukup populer pada masanya. Permen kapas dibuat dari gula yang diberi pewarna makanan, permen kapas dibuat menggunakan sebuah alat khusus yang berputar  dan menghasilkan serat – serat gula yang halus.

Fuel shortage is a common problem in Indonesia. This prompted many cases of vehicle fuel theft. As a solution to this problem, an Arduino-based vehicle fuel theft detector system is implemented. Arduino-based vehicle fuel theft detector system is a prototype that uses Arduino UNO as a microcontroller, IComSat v1.1 SIM900 GSM/GPRS Shield to communicate with mobile phone, fuel level sensor as a volume detector, and push button as a detector to check whether the fuel tank’s lid is open or closed. The working principle of this system is to detect the state of the fuel tank lid. When the lid is open, the system will make a phone call. Then, the system will keep track of fuel volume. If there is a drastic decrease in volume, the system will send information about the decreasing volume in the form of a short message to the owner of the vehicle. The success rate of the communication system between Arduino UNO and other electronic devices is 100%. Accuracy of fuel level sensor is 90%. Success rate of push button switch in detecting the state of fuel tank’s lid is 100%. Success rate of GSM Shield communication is 90%.

The objective of this work was to evaluate the yield of sawn wood and the operational efficiency in the sawing of Hovenia dulcis logs in a portable sawmill, as well as to evaluate the behavior of the wood in conventional kiln drying. For this purpose, five trees were selected, from which 14 logs of 1.8  meters in length were obtained to determine the volume, the yield of two diametric classes (20 to 24 and 24.1 to 28 cm) and the operational efficiency during the sawing of the logs. For the drying process, the parameters of initial temperature, final temperature and drying potential were obtained from the drastic drying method at 100ºC. The yield results showed that there were no statistical differences between the two diametric grades. For operational efficiency, the highest diameter class (1.00m³/worker/day) was higher than the lower diameter class (0.70m²/worker/day). For the drying of Hovenia dulcis wood, it is possible to consider this species as a difficult drying type according to the parameters found for the elaboration of the drying programs. In addition, the moisture loss of the wood occurred slowly due to its low permeability.

The effect of neutrino cooling of possible primary regions filled by hot matter is discussed. Such regions could be obtained from the primordial density inhomogeneities and survive up to the modern epoch. The inhomogeneities could be caused by a symmetry breaking during the inflationary stage. We show that the final temperature of such region should be ∼10 keV provided that the initial temperature is within the interval 10 keV ÷ 100 MeV. The cooling is realized due to the weak nuclear reactions containing n−p transition. The lower limit 10keV is accounted for by suppression of the reactions rates because of the threshold effect and particle concentration decrease.

This investigation is concerned with the cooling of 4-gal batches of custards and puddings from an initial temperature of 140°F to a final temperature of 60°F, using a rotating cold tube agitator. Variables were: (a) level of egg, (b) level of cornstarch, (c) level of sugar, and (d) rate of cold-tube agitation. Total cooling time decreased as the rate of agitation increased. All but one of the forty-eight mixtures cooled within 3 hr when agitated at 18 rev/min; all but five cooled within 5½ hr. when agitated at 6 rev/min. As the level of egg in the mixture increased the total cooling time decreased. As the level of sugar increased the total cooling time also increased, but the increase in total time was not in proportion to the increase in the level of sugar. In each instance, agitation at 18 rev/min produced a greater increase in radius of spread. Cornstarch was the most significant factor influencing the change in density of the mixtures. There was a greater increase in density value in the mixtures made with the high level of cornstarch than in the mixtures made with the low level of cornstarch. As the level of egg in the mixtures increased, the differences in density value also increased.

The isolation failure of cement-formation interface is an important and urgent problem in oil production, while an effective way to solve it is to realize the integrated solidification and cementation of cement-formation interface (ISCCFI). In order to study the kinetics of ISCCFI with MTA (Mud Cake to Agglomerated Cake) method, the Diamond Differential Scanning Calorimetry Analyzer is adopted for experiments with dynamic method and isothermal method. The results show that there is a linear relationship between the solidification reaction temperature and the heating rate of ISCCFI with MTA method. For the first exothermic peak, the initial temperature, peak tip temperature and final temperature are 53 °C, 69 °C and 83 °C respectively, and the apparent activation energy of solidification reaction is 44.39×10-3 kJ.;mol-1, the natural logarithm of preexponential factor is 7.26, the solidification reaction order is 0.88. For the second exothermic peak, the initial temperature, peak tip temperature and final temperature are 83 °C, 92 °C and 114 °C respectively, and the apparent activation energy of solidification reaction is 99.14×10-3 kJ.;mol-1, the natural logarithm of preexponential factor is 24.77, the solidification reaction order is 0.94. The maximum solidification reaction rates at 50 °C, 75 °C and 90 °C are 0.09×10-3 s-1, 0.27×10-3 s-1 and 0.51×10-3 s-1 respectively. The kinetic models of ISCCFI with MTA method under different temperatures are established. It provides a theoretical and technical support for the isolation improvement of cement-formation interface.

We investigate the inverse problem in the heat equation involving the recovery of the initial temperature from measurements of the final temperature. This problem is extremely ill-posed and it is believed that only information in the first few modes can be recovered by classical methods. We will consider this problem with a regularizing parameter which approximates and regularizes the heat conduction model.
