Abstract

This study aims to examine whether the Problem-Based Learning (PBL) model assisted by PhET Simulation has an effect on students’ critical thinking skills. The type of research used was a quasi-experimental design with a non-equivalent control group design. The population in this study consisted of all grade XI science classes at SMA Negeri 1 Gerung. The sample was selected using saturated sampling, with class XI F (36 students) as the experimental group and class XI G (34 students) as the control group. The experimental group received treatment using the Problem-Based Learning (PBL) model assisted by PhET Simulation, while the control group was taught using conventional learning methods. The test instrument consisted of five essay-type questions. The hypothesis was tested using the Independent Samples t-test at a 5% significance level, which produced a significance value of 0.001 for students’ critical thinking skills. Since this value is smaller than the 5% significance level (0.050), H0 was rejected and Ha was accepted. These results indicate that the PBL model assisted by PhET Simulation has a significant effect on students’ physics problem-solving skills, further supported by the higher N-Gain score of the experimental class compared to the control class.

Abstract

Kegiatan Pengabdian kepada Masyarakat ini bertujuan untuk meningkatkan pemahaman konsultan terhadap penerapan Analisa Harga Satuan Pekerjaan (AHSP) terbaru berdasarkan Surat Edaran Direktur Jenderal Bina Konstruksi Nomor 68/SE/Dk/2024 yang mengacu pada Permen PUPR Nomor 8 Tahun 2023. Sosialisasi dilaksanakan di CV. Bina Engineering Consultant, Kota Palembang, dengan metode ceramah dan diskusi interaktif antara tim pengabdian dari Jurusan Teknik Sipil Politeknik Negeri Sriwijaya dan peserta dari pihak mitra. Kegiatan ini memberikan penjelasan mengenai perubahan komponen harga satuan, penambahan item pekerjaan baru, serta dampaknya terhadap perhitungan anggaran biaya proyek konstruksi. Hasil kegiatan menunjukkan peningkatan pemahaman peserta terhadap regulasi terbaru dan penerapannya di lapangan. Peserta juga menunjukkan antusiasme tinggi selama diskusi serta memberikan umpan balik positif terhadap materi dan metode penyampaian. Sebagai tindak lanjut, tim pengabdian merencanakan penyusunan artikel ilmiah, modul pelatihan, dan laporan evaluasi kegiatan. Kegiatan ini diharapkan memperkuat sinergi antara dunia pendidikan dan dunia industri dalam penerapan regulasi teknis konstruksi yang mutakhir.

Abstract

West Nusa Tenggara is a region prone to natural disasters, requiring strategies to strengthen food security as part of efforts to build community resilience. One potential alternative is mushroom cultivation based on simple technology. This community service activity aims to introduce and implement a technologically advanced mushroom cultivation model to support food security and disaster resilience in Sembalun Bumbung Village, East Lombok. The method used was participatory training with a learning-by-doing approach, involving the local community in all stages of mushroom cultivation, from media preparation and sensor-based environmental control to harvesting and post-harvest. The results of the activity showed that most participants initially lacked knowledge of mushroom cultivation, but after the training, there was an increase in interest and understanding of the economic and consumption benefits of mushroom cultivation. The implementation of mushroom houses with technology to monitor temperature, humidity, lighting, and biogas utilization was deemed effective and easily adopted by the community. Technologically advanced mushroom cultivation has the potential to become an adaptive and sustainable local food source, thus supporting food security and community resilience in the face of natural disasters.
