2026-02-19T20:26:31+07:00

Peer acceptance plays an important role in students' social development because it affects self-confidence, participation, and psychosocial adjustment. Observation results indicate that there are still difficulties in social interaction and emotional management in grade X students, so it is important to examine these variables. This study used a quantitative approach with a correlational design on 170 students selected through random sampling techniques at SMA Negeri 13 Samarinda. Data were collected using scales of social skills, emotional regulation, and peer acceptance that have been tested for validity and reliability. Data analysis was carried out using product moment correlation and multiple linear regression using SPSS. The results showed a positive relationship between the variables studied with different levels of strength. Social skills (X1) and emotional regulation (X2) have a correlation coefficient of r = 0.563 which is included in the moderate relationship category, indicating that the better an individual's social skills, the better their emotional regulation. The relationship between social skills (X1) and peer acceptance (Y) is also in the moderate category with r = 0.510, indicating that individuals with better social skills tend to be more easily accepted by their peers. Meanwhile, emotional regulation (X2) and peer acceptance (Y) had a low positive correlation with r = 0.252. Simultaneously, social skills and emotional regulation had a significant relationship with peer acceptance (p < 0.05). However, partial regression results showed that only social skills had a significant effect on peer acceptance, while emotional regulation did not contribute significantly. This finding suggests that social skills are a more dominant factor in influencing an individual's acceptance by their peers.

Analisis Perbandingan Premi Asuransi Jiwa Berjangka Model Diskrit dan Kontinu dengan Suku Bunga CIR

2026-04-07T20:26:17+07:00

This study aims to analyze and compare the calculation of the net single premium of term life insurance using the discrete and continuous model approaches with the Cox-Ingersoll-Ross (CIR) stochastic interest rate. The data used are the BI Rate interest rate for the period January 2022 to February 2026, as well as the 2023 Indonesian Population Mortality Table (TMPI) for the female category. The CIR model parameter estimation was carried out using the Ordinary Least Squares (OLS) method. The estimation results show that the model has mean reversion characteristics with a long-term average of 0.05 (5%) and a variance of 0.0000002, which indicates relatively stable interest rate fluctuations. The interest rate rate (force of interest) is obtained at δ = 0.036025. Furthermore, the model is used to calculate the discount factor and premium. The calculation results show that the net single premium with the discrete approach is Rp 911,088.22, smaller than the continuous approach of Rp 927,703.73. This difference is due to the timing of benefit payments. The discrete model assumes payment at the end of the year of death, while the continuous model assumes payment at the time of death. Therefore, the continuous approach yields a greater present value of future benefits. This study shows that the choice of premium model and interest rate assumptions significantly influence premium amounts.

Analisis Perbandingan Premi Asuransi Jiwa pada Model Suku Bunga Deterministik dan Stokastik Berbasis Model Vasicek

2026-04-07T20:36:40+07:00

This study aims to analyze the comparison of life insurance premiums calculated using a deterministic interest rate model and a stochastic model based on Vasicek. Differences in interest rate assumptions are evaluated based on their impact on the Expected Present Value (EPV) and the resulting premium. The deterministic approach uses a constant interest rate of 4.93% based on the average BI Rate for the 2016–2025 period, while the stochastic approach applies the Vasicek model with Monte Carlo simulation to represent interest rate fluctuations. The data used include historical interest rates and the 2019 Indonesian Mortality Table (TMI). The results show that the EPV Benefit in the Vasicek model is 1.16% higher than the deterministic model, which results in a premium increase of 0.36% (Rp 173,592 compared to Rp 172,967). This relatively small difference indicates that the premium sensitivity to interest rate changes in this study is relatively low. This study confirms that the Vasicek model provides more realistic estimates because it captures interest rate dynamics. However, the significance of the differences is significantly influenced by the level of volatility. Therefore, the use of stochastic models in premium determination becomes more relevant in conditions of highly fluctuating interest rates.

Analisis Sensitivitas Premi Asuransi Jiwa Berjangka terhadap Suku Bunga dengan Model CIR Berdasarkan Volatilitas & Waktu

2026-04-07T20:56:46+07:00

This study aims to analyze the sensitivity of term life insurance premiums to interest rate changes using the Cox-Ingersoll-Ross (CIR) model by considering volatility and coverage period. The study uses interest rate data for the 2021–2025 period obtained from the Central Statistics Agency (BPS) and the 2019 Indonesian Mortality Table (TMI), with a case study of a 30-year-old insured, a sum insured of IDR 100,000,000, and tenors of 5, 10, and 20 years. The results show that the premiums of the CIR model are consistently higher than those of the fixed interest rate model by a difference of around 0.5%–1.5%. Quantitatively, an increase in the interest rate from 3% to 7% significantly reduces the premium, while an extension of the coverage period increases the premium proportionally. Meanwhile, interest rate volatility has a relatively small effect on the premium, in line with the low value of the volatility parameter (σ = 0.00549). Thus, interest rates and coverage terms are the dominant factors in determining premiums, while volatility has a limited influence in the model used.

Acne (Acne vulgaris) is a skin problem often caused by Propionibacterium acnes bacterial infection. Guava leaves (Psidium guajava L.) contain antibacterial compounds, but their use as facial cleansing cosmetic preparations in the form of micellar water has not been widely done. This experimental study aims to determine the feasibility of guava leaf extract micellar water preparations in inhibiting the growth of Propionibacterium acnes. The preparations were formulated into two variations of extract concentration, namely F1 (50%) and F2 (100%). The evaluation stage of the preparations included organoleptic tests, homogeneity, pH, viscosity, and antibacterial activity testing using the well method. The results of physical tests showed that both formulas were liquid in texture, dark brown in color, and had a distinctive odor of guava leaves. However, the preparations were proven to be inhomogeneous due to the presence of particle deposits. The average pH value of the preparations was classified as acidic and was below the physiological standard of the skin (<4.5) which was 3.05 for F1 and 3.19 for F2. Antibacterial testing showed weak inhibition (<5 mm), with an average F1 inhibition zone of 0.961 ± 0.0300 mm and F2 of 1.142 ± 0.0226 mm. One-way ANOVA analysis showed a statistically significant difference between the treatment groups (p<0.05). However, the preparation was not yet clinically effective, thus concluding that guava leaf extract micellar water is not yet suitable for optimal application due to the physical instability triggered by the high extract concentration and its inadequate ability to penetrate the complex cell wall of Propionibacterium acnes. Further research is needed to optimize the formulation of this preparation.

This research is motivated by the low mathematical literacy skills of students at SMPN 5 Medan. The low mathematical literacy skills are caused by several factors, namely conventional learning and the use of interactive learning media and technology that has not been utilized optimally. One effort that can be done to improve these skills is through the application of the Realistic Mathematics Education (RME) approach assisted by GeoGebra. This study aims to determine the effect of the RME approach assisted by GeoGebra on students' mathematical literacy skills in geometry material. This study uses a quantitative approach with a quasi-experimental method and a pretest posttest control group design. The research sample was determined using a purposive sampling technique, so that two classes were obtained as samples, namely class VIII-8 as a control class consisting of 30 students, and class VIII-1 as an experimental class consisting of 30 students. The research instrument was a mathematical literacy ability test given before and after treatment. Data analysis with hypothesis testing using an independent sample t-test. The test results obtained a t value = -3.718 with a sig. The value of 0.000 < 0.05 indicates that H0 is rejected and H1 is accepted. Therefore, it can be concluded that the GeoGebra-assisted RME approach has a positive and significant effect on students' mathematical literacy skills.
