Abstract

Engineering Physics is a discipline that integrates concepts from physics, mathematics, and engineering to provide solutions to various technological challenges. The community service activity aimed to discuss the role of Engineering Physics in technological development with students at SMKS Lachairoi Kotaraja. Engineering Physics contributes to the development of innovative technologies such as renewable energy, environmental sensors, medical devices, and industrial automation. The methods used in this community service activity included expository presentations (verbal delivery of material) and demonstrations with teaching aids, focusing on fostering critical and analytical thinking related to physics and the role of Engineering Physics in technology. The results of this activity showed that the students applied physics principles in the design and functionality of technologies such as communication technology, optical and photonic technology, and computational technology

Abstract

Rivers play a crucial role in ecosystems and human life. Accurate understanding of hydraulic characteristics, such as flow velocity and discharge, is essential for sustainable water resource management, flood mitigation, infrastructure planning, and aquatic ecological studies. To comparatively examine the hydraulic characteristics of a river, this study was conducted on a micro scale using the float method, with simulations performed on the Toladan River.The research was carried out in the Toladan River Watershed (TRW) located in Jayapura Regency, mapped on a small scale and divided into three observation points, with a total observation area of approximately 514.75 m².Measurements were conducted using the float method, with the floating object being a cardboard box measuring 4 cm × 3 cm × 2 cm. The data collected consisted of the travel time of the water flow, which was used to calculate flow velocity and discharge. The results showed that the highest flow velocity was recorded at the first observation point at 0.367 m/s, followed by the second point at 0.331 m/s, and the third point at 0.148 m/s. In contrast, the highest discharge was observed at the third point, reaching 0.654 m³/s, followed by the second point at 0.448 m³/s, and the lowest at the first point with 0.382 m³/s. These findings indicate a linear relationship between flow velocity and discharge, influenced by the cross-sectional area of the stream: lower flow velocity with higher discharge suggests a wider cross-sectional area. The results also show that discharge in the Toladan River is not constant and that flow velocity is affected by watershed size, river depth, and watershed slope.

Abstract

This Community Service (PKM) activity aims to integrate mathematical concepts with Papuan local wisdom through an ethnomathematics approach. This program was implemented at the Ayapo Reading House, Ayapo Traditional Village, Sentani and involved 30 students consisting of grades 4-6 of Elementary School (SD). The learning method used exploration of traditional Papuan arts such as wood carving (Ohote), bark painting (Khombow), local batik motifs (Hote Hiloi, and Yoniki) to introduce the concept of patterns and symmetry in mathematics. A multisensory approach was applied through clapping activities, rhythmic tapping, and pattern drawing exercises. The results of the activity showed an increase in students' interest in mathematics and their ability to identify patterns and symmetry in Papuan culture. As many as 94% of students became prouder of their cultural heritage after understanding that traditional Papuan art contains complex mathematical concepts. This shows that ethnomathematics learning not only improves numeracy literacy but also strengthens students' cultural identity. This program has successfully proven the effectiveness of local cultural integration in STEM learning, especially for education in 3T (Frontier, Outermost, and Disadvantaged) areas.
