Abstract

This study discusses the effect of using Student Worksheets based on Realistic Mathematic Education (RME) on student learning outcomes at MTs Jauharul Iman, Senaung Muaro Village, Jambi on the subject of the Pytagoras Theorem. This study aims to determine whether the use of RME-based LKPD can improve student learning outcomes. This research is a quantitative study using the Quasi Experimental Design method with the research design Nonequivalent Control Group Design. The sampling technique used random sampling by taking all the population into a sample, where class VIII A consisted of 19 students as the control class and class VIII B had 19 students as the experimental class. The data collection technique was carried out using a multiple-choice test totaling 16 questions. The analysis in this study used the t_test test and the phi correlation test. From the results of the ttest test at the dan  significance levels, it was found that . Because  and from the results of the analysis at the significance level of dan  it was obtained  because    was rejected, meaning that there was a significant effect between student learning outcomes in the experimental class and the control class. Thus, it can be concluded that the learning outcomes of students who use the RME-based LKPD are better than the learning outcomes of students who use Scientific-based LKPD

Abstract

Family functions consist of physical maintenance, socialization and education, acquisition of new family members through procreation or adoption. Control of social and sexual behavior, maintenance of family morals and maturation of family members through forming sexual partners and releasing adult family members. ¬ However, current conditions describe conditions that indicate that the role of the family in building and nurturing family members is increasingly weak. This study aims to determine whether there is a significant influence between the implementation of eight family functions on the social status of adolescents in Jambi province. This research is a quantitative study using SKAP 2018 secondary data (families and youth) so it is expected that the results of this study can be representative of the population studied. the level of vulnerability of adolescent association in Jambi Province shows the number 53.33. This means that most of the teenagers in Jambi Province are dating. Overall, the implementation of eight (8) family functions has no significant effect on the social status of adolescents.

Abstract

This research develops the appropriate formula to determine insurance premiums on agricultural commodity prices that provide coverage to policyholders for losses caused by falling prices. The price component is assumed to follow the Brownian Geometric motion in determining the insurance premiums for agricultural commodity prices. So, through the Ito process, a target price can be selected and is used as a reference to determine whether a claim can be made or not at harvest time. The approach of the Black-Scholes model is used to construct an appropriate model to determine insurance premiums of agricultural commodity prices due to a decrease in prices from the expected price. A simulation study is carried out using daily price data for red chili commodities in the Jambi province in 2020 with several assumptions made based on literature studies and farmers’ common habits in Jambi. The simulation results indicate that the average return is -0.001069649, and the standard deviation is 0.07297269. Thus, the expected estimated value of the profit rate is -0.001069649, and the estimated volatility value is 0.07297269. Furthermore, using the target price value, the red chili price insurance premium for a one-planting period with an area of one hectare is Rp. 1,527,088.Keywords: agriculture insurance; Black-Scholes model; European option; Ito process. AbstrakPenelitian ini mengembangkan formula yang sesuai untuk menetapkan harga premi asuransi harga komoditas hasil pertanian yang memberikan pertanggungan kepada nasabah atas kerugian yang disebabkan oleh turunnya harga. Dalam menentukan premi asuransi harga komoditas hasil pertanian, komponen harga diasumsikan bergerak mengikuti Gerak Brownian Geometrik. Sehingga melalui proses Ito dapat ditentukan target harga yang akan dijadikan acuan untuk menentukan klaim atau tidaknya nasabah pada saat panen. Pendekatan model Black-Scholes digunakan untuk mengkonstruksi model yang sesuai untuk menentukan premi asuransi harga komoditas hasil pertanian yang disebabkan karena turunnya harga komoditas dari harga yang diharapkan. Simulasi dilakukan menggunakan data harga harian komoditas cabe merah di Provinsi Jambi tahun 2020 dengan beberapa asumsi yang dibangun berdasarkan kajian literatur dan kebiasaan umum petani di Provinsi Jambi. Hasil simulasi menunjukkan bahwa rata-rata return adalah -0,001069649 dan standar deviasi 0,07297269. Sehingga diperoleh nilai estimasi tingkat keuntungan yang diinginkan sebesar -0,001069649, dan nilai estimasi volatilitas sebesar 0,07297269 . Selanjutnya, menggunakan nilai target harga diperoleh premi asuransi harga cabe merah untuk 1 periode tanam dengan luas lahan 1 hektar sebesar Rp. 1.527.088.Kata Kunci: asuransi pertanian; model Black-Scholes; opsi eropa; proses Ito. 2020MSC: 62P05
