The study aims to identify the effect of learning motivation and self-regulated learning on learning achievement in “Derivative” learning materials in Trigonometry Functions. The study was field research using the ex-post facto design and quantitative approach during the Covid-19 Pandemic. The population was all grade XII students of a state Islamic senior high school in South Kalimantan, Indonesia. The samples of 24 students were selected using the purposive sampling technique. The data were gathered using a questionnaire and test and through documentation and interview. The data were analysed using the descriptive statistics and the inferential statistics consisting of normality test, linearity test, multicollinearity test, heteroscedasticity test, and multiple linear regression. The result shows that there is an effect of motivation and learning independence during the Covid-19 pandemic, which contributed 90.9% in increasing mathematics learning outcomes, and the rest was affected by other variables. This result is based on the results of F-test (Fcount = 104.948 Ftable =3.47) at the significance level of 5% with a multiple linear regression model Ῠ= 13.557+0.435 X1+0.395 X2 + ɛ.

This study aims to describe the difference in creativity and mathematics achievement between gifted students who were taught by Treffinger's learning and those who thought by the expository learning in trigonometry material. This study is a quasi-experiment using a pretest-posttest group design with a population of all gifted students in class X of a State Senior High School in Bali, Indonesia. The sample was established randomly. Observation sheets, pre-test, post-test, and student creativity questionnaires were used, all of which have been validated. The data were analyzed descriptively and inferentially with the paired sample t-test to test the mean difference of the pre-test and post-test data. The results show that the average creativity of students in the experimental class is significantly higher by 9.46 points than that of the control class. In terms of mathematics learning achievement, the average gain score in the experimental class increased significantly by 58.365 points. It can be concluded that Treffinger’s learning is effective in increasing creativity and mathematics achievement of gifted students in trigonometry material.

This quantitative-qualitative descriptive study aims to reveal the mathematics understanding of prospective student-teachers, describe the types of their mistakes in mathematics understanding, and recommend appropriate teaching of mathematics understanding. The subjects were 34 first-year students taking the Geometry course in the Mathematics Education Study Program, at a State University in Yogyakarta, Indonesia. The test instrument was consisting of four items, two of which were about the problems of procedural instrumental understanding and the other two were about the problems of relational understanding. The data were analyzed through the stages of reducing data, presenting data, and concluding data. The results show that students' mathematical understanding is categorized as good (87.75%). Students' procedural instrumental understanding (87.75%) is better than their relational understanding (77.52%) which is in good and sufficient categories, respectively. Some students made mistakes in representing theorems, performing mathematical procedural using appropriate concepts/theorems, and interpreting conclusions or proofs using appropriate notation and representation. It is recommended that mathematical learning should prioritize relational understanding by exploring a concept with other concepts and using various representations, situations, and contexts. Learning should focus more on relational understanding, namely discussing a concept and its relationship with other concepts with different representations, situations, and contexts.

This study aims to describe the reasoning abilities of high school students in Pandeglang Regency, Indonesia in solving post-Covid-19 PISA model math problems. The subjects of this study were 80 students of two state senior high schools in Pandeglang Regency, Indonesia. The data collection used a written test consisting of four description questions in the form of PISA model math questions (levels 2, 3, 4, and 5), and were through interviews and documentation. The data analysis followed the steps of data reduction, data presentation, and conclusion drawing. The results show that the reasoning abilities of Pandeglang Regency high school students in post-Covid-19 are fair in following the rules of inference, checking the validity of arguments, proving, drawing logical conclusions, using patterns, analyzing mathematical situations, and generalizing. However, the reasoning abilities were very poor in providing explanations of models, facts, characteristics, and relationships; constructing valid arguments; and studying conjectures. Thus, it can be concluded that the mathematical reasoning ability of Pandeglang Regency senior high school students is poor when measured using the PISA Post-Covid-19 model of mathematics questions.

The provider company on the covid-19 pandemic became an interest in investors to invest. Investing certainly has a risk then investors must have an analysis to know what to bear during investing is like making a portfolio. In determining the optimal portfolio there are several models that one of them can use is the Markowitz model. Specifies an optimal portfolio with Markowitz models only reserved for investors who want the smallest risk outcome with a particular profit. The results earned for the investor's optimal portfolio could instill its funds on each provider's shares, on W shares with a fund proportion of 0.48%, on X shares with a fund proportion of 50%, on Y shares with a fund proportion of 49.5% and on Z shares with a fund proportion of 0.11%. The optimal portfolio formed gives a portfolio return expectation of 7.53% with a portfolio risk or risk that investors will bear is as much as 9.95%. Perusahaan provider pada pandemi covid-19 menjadi ketertarikan para investor untuk berinvestasi. Berinvestasi tentunya memiliki risiko maka investor harus memiliki analisis untuk mengetahui apa yang akan ditanggung selama berinvestasi seperti membuat suatu portfolio.

Gold is one of investment that can provide attractive benefits in the future. One of the advantages of investing in gold is that the value of its assets is not significantly eroded by inflation. Although gold prices tend to be stable, investment risks remain. Therefore we need a method that can help to find out the prediction of the gold price at the time that will be the basis for making a decision. One of them is by using Fuzzy Time Series Lee's method. Fuzzy time series lee's method is a combination of fuzzy logic concepts with time series forecasting that can solve forecasting problems. This article discusses gold price forecasting at PT.

Artificial bee colony algorithm is inspired by the honeybee's behavior in finding foods. In finding foods, the bees have 3 divisions that play an important role: the employed bees, the onlooker bees, and the scout bees. In this paper, the artificial bee colony algorithm implemented on the shipping problem conducted by courier. The courier should find the shortest route by passing through each and every specified location and coming back to the first location to deliver the packages in a short time. The efficient route to deliver the packages is solved by optimizing the travelling salesman problem. PT Pos Purwakarta has 18 drop-off locations. Using the artificial bee colony algorithm, the effective route was established with total range of 95.9 km. Algoritma artificial bee colony ini terinspirasi dari perilaku lebah madu dalam mencari makanan. Dalam mencari makanan lebah tersebut memiliki 3 pembagian kerja, yaitu employed bees, onlooker bees, dan scout bees. Algoritma artificial bee colony dapat diimplementasikan dalam masalah pengiriman paket oleh kurir. Penyelesaian travelling salesman problem menggunakan algoritma artificial bee colony untuk mencari rute terpendek dengan melewati setiap lokasi yang ditentukan tanpa ada yang terlewat dengan kembali lagi ke lokasi awal agar seorang kurir dapat mengantarkan paket-paket tersebut dengan waktu yang singkat, sehingga masalah yang terjadi seorang kurir harus menemukan rute yang efisien di antara rute lainnya agar dapat menjalankan tugas dengan baik. Berdasarkan hasil program yang dilakukan pada 18 lokasi pengantaran oleh seorang kurir dengan menggunakan algoritma Artificial Bee Colony pada studi kasus pengiriman paket PT Pos Purwakarta memperoleh hasil rute dengan total jarak yaitu 95,9 km.
