Abstract

Indonesia merupakan negara maritim yang sebagian penduduknya bermata pencaharian sebagai nelayan. Maritim sendiri merupakan semua kegiatan yang berlangsung di kawasan pesisir lautan dan kawasan perairan. Pada artikel ini penulis ingin mengetahui surplus produsen dan konsumen pada industri perikanan lebih tepatnya pada ikan cakalang dan belang kuning. Penelitian ini merupakan penelitian kualitatif dengan metode library research. Objek penelitiannya adalah surplus produsen dan konsumen penjualan ikan cakalang dan ikan belang kuning. Sebelum mencari surplus produsen dan konsumen terlebih dahulu mencari fungsi penawaran (QS) dan fungsi permintaan (Qd). Berdasarkan hasil analisis dari pembahasan bahwa kepuasan yang lebih banyak berada pada produsen yang artinya menyebabkan kesejahteraan petani yang dicerminkan nilai surplus produsen meningkat. Tetapi permintaannya cenderung rendah akan membuat nilai surplus menjadi negatif.

Abstract

The research's background is students' poor representation skills.  This investigation sought to determine how the Adversity Quotient (AQ) and Missouri Mathematics Project (MMP) learning models affected students' capacity for representation of mathematics. During the even semester of the 2023–2024 school year, this research was conducted at one of the MTs in South Tangerang City. Using the cluster random sampling method, 45 learners were chosen for the study, 23 of them were from the experimental class and 22 from the control class. Each class is divided into three levels of AQ which are students with Quitters, Camper, and Climber types. This study used a design similar to an experiment with a control group that was only included in the post-test. The data analysis technique used is two-way ANOVA testing. The findings of the investigation indicate that 1) students' mathematical modeling skills are influenced by their acquisition of model; 2) students' mathematical representation skills are influenced by the AQ type; and 3) there is no interaction effect between the AQ type and learning model on pupils mathematically illustration skills.
