Abstract

This study aims to identify how influential the principal's leadership and teacher's personality competency are on the learning motivation of students at State Junior High Schools in Meureubo District, Aceh Besar Regency. This study uses a quantitative approach with a correlation research type because it wants to see the cause and effect or influence between variables, namely the influence of principal leadership, teacher's personality competency on student learning motivation. Based on the results of the analysis and identification that have been carried out, it is proven that the principal's leadership and teacher's personality competency have a significant effect on the learning motivation of students at State Junior High Schools in Meureubo District, Aceh Besar Regency, as evidenced by the R Square value of 38.8%.

Abstract

Kelapa sawit dan pinang merupakan dua dari beberapa komiditi unggulan sub suksektor perkebunan Kabupaten Aceh Utara yang pengembangannya lebih didominasi oleh perkebunan rakyat. Meskipun perkebunan kelapa sawit  lebih luas dibandingkan perkebunan pinang rakyat namun harga jual kelapa sawit yang berupa Tandan Buah Segar (TBS) sangat fluktuatif dan cenderung menurun, sedangkan harga pinang relatif stabil. Adapun tujuan dari penelitian ini adalah menganalisis kedua jenis usaha tersebut dari aspek  biaya dan pendapatan karena kedua hal ini berpengaruh terhadap kesejahteraan petani.  Metode analisis yang digunakan  adalah metode analisis deskriptif kuantitatif untuk menganalisis biaya dan pendapatan. Analisis Independent T-test digunakan untuk menganalisis perbandingan/kesenjangan pendapatan dari kedua usaha tersebut.  Hasil analisis menunjukkan bahwa baik biaya produksi maupun pendapatan bersih dari  pinang jauh lebih tinggi dibandingkan kelapa sawit pada perkebunan rakyat Di Kabupaten Aceh Utara. Selanjutnya hasil analisis perbandingan pendapatan dengan dengan menggunakan Analisys Independent Sample T tes.  menunjukkan bahwa terdapat perbedaan pendapatan yang signifikan antara perkebunan kelapa sawit dengan perkebunan pinang. Rata-rata pendapatan bersih perkebunan pinang lebih tinggi dibandingkan dengan perkebunan kelapa sawit. Perbedaan tersebut antara lain disebabkan TBS sering fluktuatif dan cenderung rendah  dibandingkan harga pinang. Selain itu, petani kelapa sawit di lokasi penelitian tidak memiliki hak untuk menentukan harga karena harga jual mengikuti harga yang berlaku. Berbeda halnya dengan petani pinang yang memasarkan dalam bentuk pinang kering sehingga harga jual cenderung lebih stabil.  Jika harga pinang terlalu rendah, umumnya petani akan menyimpan pinangnya sementara waktu sampai harga stabil kembali.

Abstract

This study discusses the analysis of the Spruce Budworm model using numerical methods, namely the Heun method and the Third Order Runge-Kutta method. The purpose of this study is to determine the numerical results of the Heun method and the Third Order Runge-Kutta method on the cypress caterpillar model and to determine the comparison of errors from the two methods, namely the Heun method and the Third Order Runge-Kutta method in analyzing the Spruce Budworm model. The results of the study using the Heun method for the initial conditions at years, for , the result obtained is and . For the calculation result of the Spruce Budworm model using the third-order Runge-Kutta method, the result obtained is and . while the error of Caterpillar Density with the third-order Runge-Kutta method is bigger than the Heun method, while the error of Branch Surface Area and the error of Reserve Food error using the Heun method bigger than using the third-order Runge-Kutta method.

Abstract

This study aims to examine the behavior of the cocoa market in Pidie Jaya Regency, using a qualitative descriptive approach and a quantitative descriptive approach. Determination of the sample of farmers using simple random sampling method, while the determination of the sample of traders using the technique of snowball sampling. The results showed that there was a tendency for farmers to sell cocoa to village collectors compared to sub-district traders because of limited transportation facilities at the location of the land. There is collusion and strategies by farmers and traders in cocoa marketing. There is a tendency for traders to determine cocoa price standards among traders and set a minimum price for farmers, so that farmers are disadvantaged. This condition shows the existence of information asymmetry related to low selling prices for farmers and is detrimental to farmers
