Abstract

System evaluation is carried out with the aim of knowing system weaknesses that hinder users from implementing them. Inventory application users in Badung Regency, based on interviews conducted, had never been evaluated and there were several records collected regarding complaints from users. This study aims to evaluate the value of the success and speed of doing tasks with Performance Measurement, RTA and SUS Techniques. Based on the results of processing the data obtained with the performance measurement technique, it shows that pages are generally quite effective because they function properly, even though there was an error in one of the tests in carrying out the task by the respondent. This is due to a period mismatch caused by the user's own error, namely forgetting to change the period. Efficiency when viewed from the results of the data obtained with performance measurement techniques, it is generally known that inventory applications are quite efficient. For user satisfaction, the score for the respondent's questionnaire is 61.18 which is obtained, this means that the score is smaller than the SUS standard score, which is 68. So it can be said that respondents are not satisfied using the Inventory Application. The results obtained from the usability testing process show that the Inventory Application page which is the object of research still does not meet the criteria for a product with good usability. This can be seen in the assessment of the level of effectiveness, efficiency, and user satisfaction. This inventory application is not able to meet the good criteria for these three aspects.

Abstract

Mother's Milk (ASI) is nutritious food for babies up to 6 months, but it is also recommended that breast milk be given to babies up to 2 years old. The benefits of breastfeeding include for antibodies in infants, avoiding allergic diseases, avoiding the risk of diseases of the respiratory tract, reducing diarrhea, reducing diabetes, and others. The problems that occur in Indonesia are several things, namely the limitations of exclusive breastfeeding due to the lack of knowledge of mothers about breast care and the lack of use of breast care in breast care for breastfeeding mothers. This can have a negative impact from not doing breast care or breast care which can have a negative impact, one of which is mastitis or tissue problems in the breast. One of the efforts to get sufficient milk production is that mothers must routinely carry out breast care, namely the use of a Breast Care tool design for the lactation process. Breast massage device or Breast Care for the lactation process can be used when mothers experience breastfeeding problems, with vibrations generated from servo motors and control motors on the device so that it can produce 3 types of vibrations that nursing mothers can use during breastfeeding.

Abstract

In the era of digitalization, business organizations are competing to improve the quality of their services by utilizing information technology. Reliable information technology applications can be used to help the company's operations become better, while improper application of information technology can slow down the process. The process of establishing information technology through IT governance audits will optimize the application of information technology in a business. The implementation of an IT audit generates plenty of data that must be appropriately managed. Audits conducted using traditional systems frequently encounter issues such as difficulties maintaining audit indicator data, manually keeping of evidence at risk of getting damaged or lost, the process for generating reports is quite long, the audit monitoring operations are ineffective, and because there are numerous types of standards with different indicators, multiple tools are required while performing audits. In order to answer these issues, this study implemented a multi standard information technology governance audit tool that capable of managing audit activity data from many standards in a single system. The PHP and javascript programming languages, MySQL database, as well as the Laravel and VueJS Frameworks, will be used in the construction of this audit tool. The SDLC method was applied in this study, with numerous stages including planning to maintenance. Through blackbox testing on the various functions contained in the developed multi-standard audit tool, it is shown that the system can function as expected or intended. As well as through the usability testing questionnaire, it was concluded that the multi-standard audit tool developed had fulfilled the usability aspects.

Abstract

Development of a recommendation system to determine recipients of Direct Cash Assistance (BLT) using the C4.5 algorithm hybrid method and decision tree. In the current era of digitalization, the BLT program is a solution for the Indonesian government to help people affected by the COVID-19 pandemic. In this study, we propose a recommendation system that combines the C4.5 algorithm and a decision tree to increase accuracy and efficiency in determining BLT beneficiaries. Primary data was obtained through interviews and observations, while secondary data was obtained from the village administration, written reports, journals, theses and previous research. The results showed that the C4.5 algorithm and decision tree hybrid method gave good performance in determining BLT recipients. The C4.5 algorithm is used to calculate the accuracy of the training data and testing data with a ratio of 80% : 20%, while the decision tree is used to create a decision tree that classifies prospective BLT recipients. This research fills in the previous research gap regarding the recommendation system for determining BLT beneficiaries. The results of this study are expected to provide useful information for the government in making decisions regarding the BLT program, especially at the village or sub-district level. With an accurate and efficient recommendation system, financial assistance can be provided to those who really need it, helping to meet the basic daily needs of affected communities.

Abstract

Keeping ornamental fish, especially guppies, is a type of ornamental fish that is widely kept because it has a very beautiful color pattern. The growth of guppies is influenced by environmental factors, including water temperature, water pH, and water turbidity. Fish feed is also a very important factor in the survival of fish. In general, the ideal temperature that can make guppies develop well between the range of 23-27 °C, the pH of the water is in the range of 6-8 pH. and the turbidity of guppy water requires a water turbidity level of 0-25 NTU. The purpose of this study is to design and create a water quality monitoring system in guupies using LoRa and automatic feeding according to realtime. The hardware used is Arduino Uno as a microcontroller, LoRa SX1278 as long-distance communication, Turbidity Sensor, DS18B20 temperature sensor, water pH sensor as LCD 16x4, RTC, Relay, Water pump. The system created can monitor the water temperature, water turbidity level, and Ph of aquarium water automatically. Testing is carried out by detecting the quality of aquarium water with all sensors simultaneously to determine the condition of the water which will later be monitored using LoRa. The test results determine if the water state is cloudy with a range of >2000 NTU, the water pump will automatically turn on until the water state reaches the range of <2000 NTU.
