Abstract

This research aims to prove the effect of the Think Pair Share (TPS) cooperative learning model on students' mathematics learning achievement in terms of logical-mathematical intelligence. The research is a quasi-experimental study. The population of the research is all seventh grade students of State Junior High Schools in Sukoharjo Regency. The data analysis technique used is a two-way analysis of variance with unequal cells. The conclusions of the research are: (1) TPS learning model produces learning achievement better than conventional learning model; (2) there is no difference in mathematics learning achievement between students with high and average logical-mathematical intelligence, and students with average and low logical-mathematical intelligence; students with high logical-mathematical intelligence have better mathematics learning achievement than those with low logical-mathematical intelligence; (3) in the group of students with high, average, and low logical-mathematical intelligence, the use of conventional and TPS learning models produces equally good learning achievements; (4) in the group of students with high and low logical-mathematical intelligence, the use of conventional and TPS learning models produces equally good learning achievements; in the group of students with average logical-mathematical intelligence, the TPS learning model produces learning achievements better than conventional learning model

Abstract

The purpose of this research was to find out the the effect of using ASSURE instructional design model based Visual Basic learning media to mathematical communication. This type of research is classroom action research. Methods of data collection of this study was by observation, test method, field note, and documentation. Data analysis techniques consist of data analysis process, data presentation, and data verification. The results of this study indicate an increase in students' mathematical communication. This is seen from the indicators: (1) the ability of students to express the symbols, notations, and mathematical equations completely and correctly before the action 31.25% and after the action 87.50%, (2) the ability of students in raising the problem / issue before action 18.75% and after action 68,75%, (3) student ability to respond problem / problem from other student before action 12,50% and after action 56,25%, and (4) ability of student to explain conclusion obtained before action 37.50% and after action 87.50%.

Abstract

Penelitian ini bertujuan untuk merancang dan membangun mesin pengaduk adonan roti serta menganalisis kinerja sistem transmisi yang digunakan. Proses pengadukan merupakan tahapan penting dalam pembuatan roti karena berpengaruh langsung terhadap kualitas dan konsistensi adonan yang dihasilkan. Metode penelitian meliputi tahap perancangan, pembuatan, dan pengujian mesin. Sistem penggerak menggunakan motor listrik berdaya 1 HP yang dipadukan dengan sistem transmisi puli dan sabuk dua tahap untuk menurunkan putaran sesuai kebutuhan operasional.Hasil penelitian menunjukkan bahwa mesin memiliki kapasitas kerja sebesar 15 kg adonan per 10 menit dengan kapasitas maksimum hingga 25 kg per siklus. Pengujian menunjukkan bahwa mesin mampu menghasilkan adonan yang homogen serta meningkatkan efisiensi waktu pengadukan hingga tiga kali dibandingkan metode manual. Analisis sistem transmisi menunjukkan bahwa putaran berhasil diturunkan dari 1400 rpm menjadi 466,66 rpm pada poros antara dan sekitar 100 rpm pada poros pengaduk, sehingga menghasilkan peningkatan torsi dan kinerja yang stabil. Secara keseluruhan, mesin yang dirancang menunjukkan kinerja yang efektif, efisien, serta didukung oleh sistem transmisi yang optimal.
