Abstract

The results of research are as follows: 1) In the aluminum pipe heating the lowest level of (CO) was 0.149 (% vol) at  the fuel blend of 70% premium and 30% ethanol, and the fuel temperature following heating was 62.1 °C meaning that the level of (CO) declines below the standard condition without the fuel heating treatment. 2) In the stainless steel pipe heating, the lowest level of (CO) was 0.158 (% vol) at  the fuel blend of 70% premium and 30% ethanol and the fuel temperature following the heating was 62.1 °C, indicating that the  level of (CO) declines below the standard condition without the fuel heating treatment. 3) In the copper pipe heating, the lowest level of (CO) was 0.159 (% vol) at  the fuel blend of 70% premium and 30% ethanol with the fuel temperature following the heating was 61.7 °C, meaning that the level of (CO) declines below the standard condition without the fuel heating treatment.  4) In the aluminum pipe heating, the lowest level of (HC) was 215 (ppm vol) at the fuel blend of 100% premium, and the fuel temperature following the heating was 54.1 °C meaning that level of (HC) is above the standard condition without the fuel heating treatment. 5) In a stainless steel pipe heating, the lowest  level of (HC) was 136 (ppm vol) at the fuel blend of 95% premium and 5% ethanol, and the fuel temperature following the heating was 54.1 °C, meaning that the level of (HC)  declines below the standard condition without the fuel heating treatment. 6) In the copper pipe heating, the lowest level of (HC) was 100 (ppm vol) at fuel blend of 95% premium and 5% ethanol, and the fuel temperature following the heating was 61.2 °C, meaning that the level of (HC) declines below the standard condition without fuel heating treatment.

Abstract

Abstract Collaborative learning is an important approach in improving the quality of vocational higher education in the era of globalization. This study aims to analyze the role of collaborative learning in improving student achievement at the Aceh Barat State Community Academy. Using a descriptive qualitative approach, this research involved in-depth interviews, observations, and documentation studies with student and lecturer participants from three D-II study programs. The results showed effective implementation of Project-Based Learning, Problem-Based Learning, and Team-Based Learning models in different study programs. Collaborative learning is proven to improve academic achievement with an increase in average GPA by 0.35 points and an increase in practical skills by 22%. In addition, there were significant improvements in soft skills: communication (28%), teamwork (35%), and problem solving (31%). The main supporting factors include institutional policy support and lecturer readiness, while the main challenges include time constraints and the diversity of student backgrounds. This study concludes that collaborative learning plays an important role in improving the quality of Community Academy graduates, but requires implementation strategies tailored to the context of vocational education. Keywords:Collaborative Learning; Vocational Education; Student AchievementAbstrakPembelajaran kolaboratif menjadi pendekatan penting dalam meningkatkan kualitas pendidikan tinggi vokasi di era globalisasi. Penelitian ini bertujuan menganalisis peran pembelajaran kolaboratif dalam meningkatkan prestasi mahasiswa di Akademi Komunitas Negeri Aceh Barat. Menggunakan pendekatan kualitatif deskriptif, penelitian ini melibatkan wawancara mendalam, observasi, dan studi dokumentasi dengan partisipan mahasiswa dan dosen dari tiga program studi D-II. Hasil penelitian menunjukkan penerapan efektif model Project-Based Learning, Problem-Based Learning, dan Team-Based Learning pada program studi yang berbeda. Pembelajaran kolaboratif terbukti meningkatkan prestasi akademik dengan kenaikan IPK rata-rata sebesar 0,35 poin dan peningkatan keterampilan praktis sebesar 22%. Selain itu, terjadi peningkatan signifikan dalam soft skills: komunikasi (28%), kerja tim (35%), dan pemecahan masalah (31%). Faktor pendukung utama meliputi dukungan kebijakan institusi dan kesiapan dosen, sementara tantangan utama mencakup keterbatasan waktu dan keragaman latar belakang mahasiswa. Penelitian ini menyimpulkan bahwa pembelajaran kolaboratif berperan penting dalam meningkatkan kualitas lulusan Akademi Komunitas, namun memerlukan strategi implementasi yang disesuaikan dengan konteks pendidikan vokasi.
