<![CDATA[Cervical cancer is one of the cancers that is of global concern because of the high mortality rate in women. Preventive measures such as early detection are needed so that patients can get treatment more quickly. Fortunately, this disease can be prevented with the role of technology to help doctors in early detection of various types of cancer. The technology developed by the researchers is using machine learning algorithms. Therefore, in this study using the C4.5 algorithm to classify cervical cancer. This algorithm aims to classify 2 classes: people who have cervical cancer, people who are healthy. The results of the experiment obtained from the C4.5 algorithm are getting an accuracy of 98.61%, precision of 98.08%, and recall of 95.24% ROC curve shows 0.982%.]]>

<![CDATA[Thermal comfort is a necessity for an activity in a room, one of the parameters is wind speed. Wind speed is the speed of air flowing horizontally and vertically at an altitude above the ground. Wind speed is influenced by differences in temperature and air pressure as well as the characteristics of the surface on which it passes. Meanwhile, air that does not move in a closed room will cause the room user to feel uncomfortable. In this study, the object used is the Siti Walidah building, which is the main building, and is one of the service buildings belonging to the Muhammadiyah University of Surakarta. The object selection is based on the circular mosque shape, which is thought to affect the wind movement pattern. The purpose of this study was to determine the wind speed and the level of comfort of building users to the wind speed on each floor, especially in non-ac areas. The research method used is a quantitative approach with measurement and qualitative descriptive analysis, namely the interpretation of data because of observations, analysis with the surfer mapping program and interviews. This study also uses the SNI 03-6572-2001 reference. The results showed that the maximum comfort for users was felt only on the second floor with an average wind speed of 0.630 m/s in the morning and 1.139 m/s during the day. While the other floors have an average wind speed of below 0.25 m/s, which indicates that the wind category cannot be felt by the user.]]>

<![CDATA[The tooling department is a department that is engaged in manufacturing dies, namely the manufacture of printing equipment to make a component / pressed part which is made according to the desired design and processed on a press machine, dies are ordered from the customer, namely the sole agent of the brand (ATPM). Manufacturing dies including project work, one of the dies manufacturing projects is the 640A dies drawing part number 53711/12 project with the current machining program time being efficient at 47.29%, but to improve service to the sole agent of the brand holder and to reduce the cost of manufacturing dies, it is necessary to increase efficiency by eliminating one ball nose cutter. This research was conducted with the aim of obtaining a more efficient machining program by conducting technical analysis on the machining program dies drawing 53711/12. Technical analysis was carried out on the 12 mm ball nose cutter and 10 mm ball nose cutter by calculating the path length, cutter load and cutter life so as to obtain elimination results on the 10 mm ball nose cutter because the cutter was less effective. The result of the elimination of one cutter is that the percentage of machining program efficiency increases to 48.72% and affects the efficiency of purchasing cutters by 4.15% and efficiency in manufacturing costs for dies drawing part number 53711/12 increased from 5.44% to 5.71%, an increase of 0.27% or Rp 1,833. 893.06]]>

<![CDATA[One of the efforts to reduce the transmission of Corona Virus Disease-19 (Covid-19) is by detecting body temperature and disinfection. Detection of body temperature is carried out as an effort to identify sufferers of Covid-19 so it is necessary to prevent them to get together with other people. Manual temperature measurement may cause burnout of staff doing this task and reduced accuracy. Therefore it is necessary to develop an automatic temperature measurement system and display the data be easily observed. Apart from measuring body temperature, another effort to prevent Covid-19 infection is to disinfect the hands. The disinfection process can be done by automatically spraying the disinfectant gel on the hands. The two processes are carried out sequentially, after the body temperature is measured and does not exceed the limit, then the disinfection process is carried out. This procedure is implemented in a gate equipped with two blades with the first blade opening when the body temperature does not exceed the limit, followed by the opening of the second blade after the automatic disinfection of the hand. The procedures are done automatically without touch to minimize physical contact. For the development of the system, an Arduino Mega 2560 microcontroller is needed, 3 MLX90614, 3 HC-SR04 sensors, 3 e18-d80nk, 1 relay, 1 DC motor pump and 2 DC blade actuator motors. The allowable body temperature limit can be determined by manual setting. Operationally this system has been tested and demonstrated the ability to work as desired, including spraying disinfectant gel. For verification of temperature measurements, there was an average deviation of 0.018% from the measurement by the sensor to the temperature measured with thermogun.]]>

<![CDATA[Introduction: In previous studies a chronotype questionnaire has been compiled using a prayer time benchmark as a measure to determine whether a person's waking or sleeping behavior is categorized as early or late. The use of questionnaires based on patient answers regarding the question of how many hours from the evening prayer time (definitive night) and dawn time (the dawn twilight) does not rule out the possibility of recall bias. Therefore, it is necessary to develop a chronotype measuring tool based on the Google Prayer Schedule application, to calculate how long from the critical point the correspondence of a sundial with a person's waking time. Purpose: Develop a sundial based chronotype measuring tool from the google application for local prayer schedules. Method: Use of a questionnaire containing waking hours, hours of sleep on weekdays and holidays, to then calculate the difference from the critical time of the sun, namely the difference with the time of sunrise and the definitive hour of the night from the google application local prayer schedule where the respondent lives. Definitively, as in previous studies, 7 items were developed, relating to these habits. Respondents filled out via google form for questions from the questionnaire. Calculation of the difference between waking/sleeping hours and definitive sunrise/night hours by researchers. The research was conducted in the period November - December 2020. Results: There were 795 respondents who participated in this study. Analysis of the 6 questions, the results of the item-total correlation were sequentially with the value of r, 0.759; 0.690; 0.883; 0.761; 0.740; 0.908 with an overall p value of 0.000. Cronbach's alpha value = 0.877. Conclusion: the chronotype questionnaire based on the distance between the hours of sleep/wake up and the midpoint of sleep relative to the rising time, curfew, midnight point, is concluded to be valid and reliable.]]>
