Abstract

The purpose of this study was to design and implement a duck egg incubator. An egg incubator is a machine that functions to take over the incubation task of a duck mother in incubating fertilized eggs from the result of crossing or mating with a male. The existing incubators work in temperature control, reversing the egg racks, but do not use an egg informing system that has been hatched. In designing this duck egg incubator based on Arduino as a controller. The temperature used must be measured by the resistance of the space or the approximate resistance of the eggs to hatch. The microcontroller used is the ATMega328 integrated on the Arduino Uno, temperature sensor, humidity sensor, humidity control system and other supporting components using Arduino. The test was carried out by comparing the DS18B20 temperature sensor with a Thermometer with an error difference of 0.15. The result of this research is the device can control the temperature not exceeding 39 ° C for hatching eggs. The device has 2 usage buttons, namely a start button (green) to perform hatching day calculations and a reset button (red) to stop hatching day calculations. The day variable that has been running is still stored in the microcontroller EEPROM (Electrically Erasable Programmable Read-Only Memory) so that if there is a disconnection or loss of a voltage power source such as a power failure and so on. The 12VDC fan on the device turns on every 30 minutes and goes out for the next 30 minutes

Abstract

The advancement of information technology has had a tremendous impact in assisting executives in making decisions. The executive information system is one of the best methods to help the leader or executive to make decisions effectively and efficiently. Not all work and procurement of goods is carried out by employees or staff of PT. Pelindo I, however, was carried out through an auction process. So far, the data collection process has been done using Microsoft Excel. Many weaknesses that occur, namely the data is not realtime and the leader cannot see the information directly and the data displayed cannot help the leader make decisions quickly. Therefore, an Executive Information System is needed so that the leadership can see directly the status of the existing auction at PT. Pelindo I. The purpose of this research is to design and build an executive information system at PT. Pelindo I with the iconix process method to display the status of the auction. The stages in designing an application using the Iconix Process method consist of nine stages, namely the process of requirements analysis, preparation of a domain model, GUI storyboard, use case diagrams, robustness diagrams, sequence diagrams, domain updates model, class diagram, implementation. The result of this research is to produce an application that displays a report on the status of the existing auction at PT. Pelindo in 2019 which is more efficient by using the iconix process method. The report that is displayed is in the form of data on contract completion, still in process, failed and returned.

Abstract

In modern-day Indonesia, having access to various forms of technology is regarded as crucial. This is because the IT skills gap will only grow worse if the government does not act swiftly to make technology more accessible to the general public. PISA suggests that schools may gain much more from incorporating IT into their curriculum if they did so. The goal of this research is to establish whether or not there are notable variations in the level of knowledge in information technology across the different provinces in Indonesia. Official data from the Central Statistics Agency for 2019-2021, including information on the number of adolescents and adults aged 15-59 with abilities in the field of ICT at the provincial level, is used in the clustering calculation. The K-means algorithm is one unsupervised learning technique for clustering data into collections with other instances that share similar properties. The results showed that the seventh cluster had the lowest DBI value of the three examined, coming in at -0.357. Cluster 0 has the lowest average percentage of the population with IT skills, at 29.32%. Only in Papua Province will you find this particular zero cluster.
