This study aimed to improved understand independency enhancement and critical thinking of learning students through based blended learning. This research combines classroom action research which refers to Stephen Kemmis and Robin Mc Taggart. This research subject were students of engineering information STMIK Duta Bangsa period 2017 / 2018. This research was conducted in two cycles and each cycle was done in two meetings. Every cycle consisted of 4 steps are preparation, action, observation, evaluation, analysis, and reflection. The subject of this research is the students who took Calculus 1. The technique of collecting data was done by assessing test result and observation, test instrument, observation sheet, and field notes. The data was analyzed by using quantitative-descriptive approach. The study showed that the strategy of blended learning proved to be succeeded in increasing understand independency enhancement and critical thinking of learning students through based blended learning in Calculus 1. This is based on the occurrence of (1) increasing of independency enhancement a rise in their ability college student in learning one who is an independent study prior to the adoption of blended learning is as much as 11,2 % and after the cycle of come to an end the application of blended learning was recorded at 88,8 %. (2) increasing in their ability college students to critical thinking between prior to the adoption of blended learning is as much as 12,4 % and over the course of his shift to be over the application of a notebook detailing the development strategy blended learning was recorded at 91,2 %Keywords: Blended Learning, independent learning, critical thinking

The study aimed to identify the influence of independence for the mathematicsÂ student learning in SMP Al Irsyad Surakarta. The subject of this research are all students of class 8 SMP Al Irsyad Surakarta, which consisted of 120 students and the samples chosenÂ with random sampling are 49 students in 3 class in the school year 2020/2021. SamplesÂ were taken using the Random sampling technique. The data of independence for the mathematics student learning using a questionnaire. This study using quasi experimental research. The prerequisite using the normality test and linearity test. The normality test by using Kolmogorov Smirnov and the linearity test by using Anova. When the a prerequisite fulfilled, so followed by the Linear Regression. The result showed there are significant impact study of independent learning. Independent learning have a positive influence of mathematics students, although the result is still below 50%. This may be affected by the lack of knowledge students learn about independence, so not been undertaken in full. The conclusions obtained that students could be more improve mathematics learning outcomes.Â Keywords: learning, independent learning, mathematics, learning outcomes

Abstract – One of the most frequent disasters in Indonesia is fire. There are situations where homeowners are not aware that their house is on fire, such as when the owner is not home or at night when the owner is sleeping. Lack of information regarding the condition of a house that has caught fire can result in enormous material losses or can endanger a person's life if the fire is not resolved immediately. In this case, it is necessary to have a monitoring system that can provide information regarding the presence of early fire symptoms that can be accessed anytime and anywhere. This system will later be able to display fire, smoke, and temperature values from sensor readings that have been stored in the Firebase Realtime Database which will later be displayed on Mobile Apps. If there is a fire there will be a warning in the form of a buzzer and notification on the smartphone and the system will spray water through the waterpump. The results of this study are a fire early warning monitoring system on a smart home system using Internet of Things (IoT) based NodeMcu. It is hoped that this system can reduce or minimize the occurrence of fires and losses due to fires.

The purpose of this qualitative research is to describe in detail the profile of students' self-efficacy in dealing with discrete mathematics courses. The subjects of this study were 21 students of class TI21A4 Informatics Engineering Study Program, Duta Bangsa University, Surakarta, who were taking a Discrete Mathematics course. The information gathering tool consisted of a self-efficacy questionnaire and a guide for interview sessions. Participants filled out a questionnaire related to self-efficacy. The output of the self-efficacy questionnaire showed that 5% of students showed a very high level of self-efficacy, 39% had a high level of self-efficacy, 33% had a moderate level of self-efficacy, and 23% experienced a low level of self-efficacy. After that, 6 students were selected to be research subjects, consisting of 2 students each with high, medium, and low self-efficacy levels. Students with high and medium self-efficacy in solving Discrete Mathematics questions do not give up easily, while students with low self-efficacy give up easily when solving these problems. Students with high and moderate self-efficacy have been able to learn independently, while students with low self-efficacy have not been able to learn difficult Discrete Mathematics material independently and need guidance from the lecturer. Even so, students with high, medium, and low self-efficacy were able to complete assignments and submit assignments on time. Students with low self-efficacy, their learning efforts are less than optimal for various reasons so that they have not been able to achieve the targeted learning achievements. While students with high and moderate self-efficacy are already optimal with regard to their learning efforts Keywords: self-efficacy; student; discrete mathematics

Skincare refers to skin care products. These products have different purposes depending on the user's skin type. Over time, public awareness and interest in skincare will increase, leading to a rapid growth of skincare products. Therefore, an Item-Based Collaborative Filtering (CF) method is used to develop a skincare recommendation system. This method will provide personalised recommendations by leveraging the behaviour data of other users with similar preferences and characteristics. This study uses user ratings and preferences for skincare products as data. This data is then used to build a CF model, which will be analysed to calculate user similarity patterns using the cosine similarity matrix. The application of the CF method demonstrates its effectiveness in matching user preferences, resulting in the most relevant product recommendations. This system not only increases the accuracy of recommendations but also helps users find products that meet their skin care needs, as the error rate in the system is 0.245.

Oyster mushroom cultivation demands the stability of the microenvironment, especially in the aspects of temperature and humidity in the barn space. Manual monitoring methods that are still commonly used are often less responsive and inefficient in capturing real-time changes in conditions. To answer these problems, this research designs and builds an Internet of Things (IoT)-based monitoring system integrated with the Ubidots platform as a control center and data visualization. This system is able to read and send precise temperature and humidity data using the Hypertext Transfer Protocol (HTTP) protocol. This system uses the DHT22 sensor which is more accurate than previous studies that generally use the DHT11 sensor. The test results show that the system works responsively, stably, and accurately in presenting real-time environmental data, with a temperature reading error rate of about ±0.5°C and ±5% humidity. The implementation of the system at the oyster mushroom cultivation site in Jonggrangan Village, Klaten Utara, proved its effectiveness in helping farmers monitor and maintain mushroom growth conditions remotely in an efficient and sustainable manner.Oyster mushroom cultivation demands the stability of the microenvironment, especially in the aspects of temperature and humidity in the barn space.
