Project scheduling is one of the crucial aspects in project management. By conducting project scheduling, a better understanding of the relationships between each activity and the overall project can be obtained, allowing for the identification of activities that can be prioritized, activities that can be performed simultaneously, and activities that are interdependent. This research aims to identify the critical path and determine the duration of project completion using the Critical Path Method (CPM) for the construction project of the New Classroom Building at SMK Negeri 1, located at Jl. Ki Hajar Dewantara No. 17, KARATON, Luwuk District, Banggai Regency. The research method employed is a quantitative descriptive approach, involving the analysis and presentation of data in numerical form to objectively describe the project conditions. Primary and secondary data are used as the main sources of information in this study. The data analysis tool applied is the Critical Path Method (CPM), a network analysis technique (network planning) that functions to determine the critical path in project execution. The research results indicate that the critical path generated by the CPM scheduling method for the New Classroom Building Construction Project at SMK Negeri 1 Luwuk is through activities A-B-C-D-G-H-K-N-Q-R-W-AE-AF-AK-AP. Based on the calculations using the CPM method, the duration for completing the New Classroom Building Construction Project at SMK Negeri 1 Luwuk is 169 working days.

Heavy metal exposure in traditional mining areas poses significant long-term public health risks. Uncontrolled mining and lack of environmental oversight increase mercury, lead, arsenic, and cadmium contamination, potentially causing neurological, cardiovascular, and cancer disorders. This quantitative-descriptive study surveyed 150 residents in three traditional mining areas using structured questionnaires, supported by laboratory analysis of water and soil heavy metal levels. Multiple linear regression was applied to identify determinants of health risk perception. Mercury and lead levels exceeded safety thresholds and were positively associated with higher perceived health risks. Perceptions were also shaped by education, information access, and personal health experiences. Risk perception is influenced by both environmental exposure and sociodemographic factors. Combining toxicology and risk communication is crucial for community-based environmental health resilience.

This qualitative study investigates the integration of Problem-Based Learning (PBL) as a pedagogical approach to develop critical thinking competencies among secondary education students. The research examines how PBL methodologies can be effectively implemented to enhance students' higher-order thinking skills within the Indonesian educational context. Through a comprehensive analysis of classroom observations, in-depth interviews with educators, and document analysis, this study identifies key implementation strategies, challenges, and outcomes of PBL integration. The findings reveal that PBL significantly improves students' analytical reasoning, problem-solving abilities, and metacognitive skills when systematically incorporated into the curriculum. Furthermore, the research highlights the importance of teacher preparation, supportive learning environments, and authentic assessment methods in maximizing the effectiveness of PBL for critical thinking development. This study contributes to the growing body of knowledge on innovative pedagogical approaches in secondary education and provides practical recommendations for educators and policymakers seeking to foster critical thinking competencies essential for 21st-century learners.

Simpang jalan merupakan titik temu arus lalu lintas yang memiliki potensi konflik sehingga perlu ditangani untuk menjaga kelancaran dan keselamatan pengguna jalan. Penelitian ini bertujuan untuk mengetahui kinerja arus lalu lintas pada simpang tiga tak bersinyal di Kota Luwuk Kabupaten Banggai Provinsi Sulawesi Tengah, serta menentukan penanganan yang sesuai terhadap permasalahan yang ada. Penelitian menggunakan metode deskriptif kuantitatif dengan survei volume lalu lintas, dan analisis dilakukan berdasarkan pedoman Manual Kapasitas Jalan Indonesia (MKJI) 1997. Lokasi penelitian mencakup simpang ruas Jalan Drs. Moh. Hatta – Jalan Tuna dan simpang ruas Jalan Tj. Branjangan – Jalan Ki Hajar Dewantoro. Hasil penelitian menunjukkan bahwa kedua lokasi memiliki nilai Kapasitas (C) yang masih di bawah ketentuan MKJI 1997 yaitu 2700 smp/jam, dengan Derajat Kejenuhan (DS) < 0,85, dan nilai Tundaan berada pada tingkat pelayanan kategori B dan C sesuai MKJI 1997 dan PM No. 96 Tahun 2015. Dengan demikian, kinerja lalu lintas pada kedua simpang masih dalam kondisi baik dan belum memenuhi syarat untuk pemasangan traffic light. Namun, untuk mengantisipasi peningkatan volume lalu lintas ke depan, disarankan penanganan berupa rekayasa lalulintas guna menurunkan nilai derajat kejenuhan agar arus lalu lintas tetap lancar.
