Abstract

This research is aimed to know: (1) Which learning did give better mathematical achievement, cooperative learning which is typed Think Pair Share (TPS) or conventional learning. (2) Did the students with higher self efficacy have better learning achievement in mathematics than the students don’t. (3) Are there any differences in learning achievement in mathematics from the students with higher self efficacy and the students with lower self efficacy in TPS learning model and conventional learning model. This research is quasi-experimental. The populations are all  students grade X mechanical automotive in Sukoharjo region. The technique of data analysis used is test analysis variation two ways with unequal cells. The conclusions are that: (1) TPS learning model produced better learning achiement than conventional model; (2) there are any differences learning achievement in mathematics from the sudents that have higher self efficacy, averege self efficacy and lower self efficacy; (3) There is no interaction between learning model with the students’ sefl efficacy toward learning achievement in mathematics.

Abstract

Perbedaan diameter master rem akan menghasilkan perbedaan tekanan hidrolik. Master rem dengan diameter lebih besar mampu menghasilkan tekanan yang lebih besar. Penelitian ini bertujuan untuk mengetahui pengaruh perbedaan diameter master rem terhadap tekanan hidrolik. Jenis penelitian adalah eksperimen dengan subjek master rem pada Honda CB150R dan Yamaha Mio Sporty. Pengumpulan data menggunakan dokumentasi, observasi, dan studi pustaka. Peneltian ini menggunakan data tabel sebagai instrument penelitian. Hasil penelitian dilakukan analisis dengan metode deskriptif. Penelitian dilakukan di bengkel Wiro Motor Sport yang beralamatkan di Kedung Batang, Ngasinan, Bulu, Sukoharjo, Jawa Tengah, 57563. diameter master rem berpengaruh langsung terhadap tekanan hidrolik yang dihasilkan, sesuai prinsip Hukum Pascal. Kemudian, Master rem Honda CB150R dengan diameter 14 mm (luas penampang 21,98 mm²) menghasilkan tekanan hidrolik rata-rata 010,54 kPa. Sedangkan, Master rem roda Honda CB150R dengan diameter master rem 25 mm (luas penampang 39,25 mm²) menghasilkan tekanan hidrolik rata-rata 073,52 kPa, atau sekitar 6,975% (7 kali lebih tinggi) dibandingkan master rem Honda CB150R Master rem dengan diameter lebih kecil menghasilkan luas penampang yang lebih kecil, sehingga mampu meningkatkan tekanan hidrolik untuk gaya tekan yang sama. Oleh karena itu, Peningkatan tekanan hidrolik berdampak pada respons pengereman yang lebih cepat, namun perlu diimbangi dengan keterampilan pengendalian untuk mencegah penguncian roda.

Abstract

Background: Female heads of households in rural areas face economic vulnerability due to limited access to productive resources and high dependence on household food expenditures. In rural households, the potential of kitchen waste and yard land has not been managed in an integrated manner. Purpose of the Study: This article aims to analyze the implementation of a community service program based on a circular economy through the integration of native chicken (layer) farming, kitchen waste management, and micro-vegetable gardens for female heads of households. Methods: The community service program used a Participatory Action Research (PAR) approach, involving participants as active subjects in problem identification, action planning, implementation, and reflection. Data was collected through participatory observation, FGDs, interviews, questionnaires, and production records. Results: The results showed a Hen Day Production rate of 70–80%, additional income of Rp 180,000–Rp 390,000 per month, and savings on vegetable purchases of Rp 40,000–Rp 60,000 per month. The integration of activities formed a circular economy flow that strengthened household economic and food resilience.
