Abstract: Creativity is one of the important skills that teachers must have today. Creativity can be defined as the human ability to generate new and valuable ideas. In addition, creativity is considered as a basic competency that needs to be possessed by students in higher education. The purpose of this study was to determine the creativity of prospective biology teachers and its relationship with students' knowledge mastery. For this purpose, a descriptive and correlational study was conducted on 13 biology pre-service students. The instrument used in this study was the Torrance creativity test based on 4 creativity indicators: fluency, flexibility, originality and elaboration. Descriptive and correlational analyses were conducted to identify students' creativity profiles and the relationship between students' creativity and their knowledge mastery. The results showed that there were three types of creativity owned by prospective biology teacher students, namely students with low (38.46%), medium (38.46%) and high (23, 07%) levels of creativity. The correlation test results show that concept mastery correlates with student creativity (r=0.3). The conclusion of this study is that prospective biology teacher students have different creativity, and there is a correlation between students' concept mastery and their creativity level so that there needs to be an effort from lecturers by designing learning strategies that can increase student creativity and concept mastery.

Abstract

This study compares the performance of three hedging strategies, Collar, Bear Put Spread, and Long Strangle, in a case study of PT GoTo Gojek Tokopedia Tbk (GOTO) stock. The analysis focuses on the risk management effectiveness and profit potential of these strategies within an emerging market context. The research utilizes weekly stock price data from July 2023 to June 2024 (54 observations). The methodological procedures include calculating returns and volatility, testing return normality using the Shapiro-Wilk test, determining European option prices using the Black-Scholes model with a 6% risk-free interest rate, and conducting profit simulations. The findings indicate that the Collar strategy provides maximum protection against stock price declines, albeit with limited profit potential. The Bear Put Spread strategy proves effective in generating returns during moderate price decreases while offering lower risk and cost. Conversely, the Long Strangle strategy possesses high profit potential during significant price volatility but carries the risk of total loss if stock prices remain stagnant. As a comprehensive comparison of these three option strategies applied to GOTO stock, this study recommends the Collar strategy as the optimal choice for risk-averse investors during bearish trends.

Abstract

Kemampuan pemecahan masalah matematika berperan penting untuk membangun proses berpikir siswa. Namun ternyata kemampuan pemecahan masalah matematika siswa masih tergolong rendah, sehingga perlu adanya analisis mengenai permasalahan tersebut. Tujuan penelitian ini untuk mengidentifikasi kesulitan siswa dalam menyelesaikan soal kemampuan pemecahan masalah berdasarkan indikator Krulik dan Rudnick pada materi sistem persamaan linear satu variabel. Subjek penelitian ini terdiri 3 orang siswa SMP Pelita YNH tahun ajaran 2022/2023. Jenis dan pendekatan pada penelitian ini yakni jenis penelitian deskriptif dengan pendekatan kualitatif. Teknik pengumpulan data pada penelitian ini yakni metode dokumentasi, tes dan wawancara. Analisis data dilakukan dengan cara membandingkan data hasil tes kemampuan pemecahan masalah berdasarkan indikator Krulik dan Rudnick, data hasil wawancara, dan angket motivasi belajar siswa. Dari hasil penelitian didapatkan kesimpulan bahwa kesulitan siswa dalam meyelesaikan soal kemampuan pemecahan masalah berdasarkan indikator Krulik dan Rudnick ditinjau dari motivasi belajar siswa adalah kesulitan dalam memberikan pemahaman materi menggunakan media lain yang mudah dipahami, kesulitan melakukan latihan soal secara kontinyu. Adapun penyebab motivasi siswa rendah adalah kurangnya pemahaman konsep pada materi yang dipelajari, kurangnya latihan soal yang diberikan, dan kurangnya media yang digunakan pada pembelajaran. Serta solusi rendahnya motivasi dan menyelesaikan siswa adalah menggunakan model dan media pembelajaran yang menarik, berlatih menyelesaikan soal.Mathematical problem solving abilities play an important role in developing students' thinking processes. However, it turns out that students' mathematical problem solving abilities are still relatively low, so an analysis of these problems is needed. This research aims to identify students' difficulties in solving problem-solving ability questions based on Krulik and Rudnick indikators in one-variable linear equation systems material. The subjects of this research were 3 students at Pelita YNH Middle School for the 2022/2023 academic year. The type and approach in this research is descriptive research with a qualitative approach. The data collection techniques in this research are documentation, tests and interviews. Data analysis was carried out by comparing data from problem solving ability tests based on Krulik and Rudnick indikators, interview data, and student learning motivation questionnaires. From the research results, it was concluded that students' difficulties in solving problem solving ability questions based on Krulik and Rudnick's indikators in terms of student learning motivation were difficulties in providing understanding of the material using other media that was easy to understand, difficulty doing continuous practice questions. The causes of low student motivation are a lack of understanding of the concepts in the material being studied, a lack of practice questions given, and a lack of media used in learning. And the solution to students' low motivation and problem solving is to use interesting learning models and media, practice solving problems.
