Abstract

Kegiatan pengabdian ini bertujuan untuk menyelaraskan konsep fisika tingkat SMA dengan pembelajaran fisika di perguruan tinggi, serta memperkuat kapasitas guru dalam mengimplementasikan Kurikulum Merdeka secara efektif. Kurikulum ini menuntut pendekatan pembelajaran yang lebih kontekstual, kolaboratif, dan berorientasi pada penguatan kompetensi abad ke-21. Melalui kegiatan workshop yang melibatkan 17 guru fisika dari berbagai SMA di Kota Metro, peserta diberikan pemahaman mendalam mengenai prinsip-prinsip utama Kurikulum Merdeka, penguatan konsep dasar fisika, serta penyusunan perangkat modul ajar yang relevan. Workshop ini tidak hanya berperan sebagai wadah transfer pengetahuan, tetapi juga sebagai forum diskusi aktif yang membuka ruang kolaborasi antara guru dan dosen fisika dari perguruan tinggi. Kegiatan ini terbukti berhasil menjembatani kesenjangan epistemik antara jenjang pendidikan menengah dan tinggi, serta membentuk jejaring profesional yang potensial untuk pengembangan pembelajaran jangka panjang. Evaluasi kegiatan menunjukkan peningkatan pemahaman peserta terhadap penyusunan perangkat ajar dan strategi pembelajaran berbasis projek. Selain itu, teridentifikasi kebutuhan nyata terhadap pendampingan lanjutan, khususnya dalam pengembangan asesmen otentik dan penguatan pembelajaran berbasis fenomena sesuai arah transformasi pendidikan nasional.

Abstract

Atomistic simulation based on computational physics of methods is used to develop accurate interatomic potentials based on DFT (density functional theory) data. The accuracy of predicting the physical properties of a material is highly dependent on the quality of the interatomic potential used. The purpose of this study is to determine the Lennard-Jones potential parameters of Al metal (epsilon and sigma) from fitting the DFT simulation output data. The use of a “robust” fitting method to reduce the influence of outliers on the potential results is very important and therefore a machine learning method is used to help find the right potential parameters. The method used is a hybrid method using DFT to generate training data, using ML (machine learning) to fit DFT data to the Lennard-Jones (LJ) potential model, and using the MD (molecular dynamics) method to validate the LJ potential parameters. Python-based programming is applied to facilitate how the three methods can be connected. The results of this study are that Al metal has an epsilon value = 0.5000 eV and sigma Al = 3.2072 Å, with a regression coefficient R2 = 0.9441 so that it can be concluded that this study can be said to be quite good and the hybrid method can be further developed to obtain the LJ potential parameter values of various other materials, especially metals.

Abstract

The rapid evolution of digital technologies, particularly live streaming features in e-commerce platforms, has significantly transformed consumer behavior while introducing new risks to consumer protection. Live streaming based commercial transactions often involve real time, visually driven interactions that encourage impulsive purchasing decisions, making traditional regulatory frameworks insufficient. This study aims to analyze the primary factors influencing consumer protection in live commerce settings by examining five core variables: product transparency, platform accountability, perceived risk, consumer trust, and digital literacy. Utilizing a qualitative exploratory approach, this research conducted a comprehensive literature review of 77 international journal articles published between 2020 and 2024. The findings indicate that product transparency and platform accountability are fundamental to enhancing consumer trust and reducing perceived risks, whereas digital literacy acts as a moderating factor that empowers consumers to make informed decisions. The study proposes a conceptual framework that integrates behavioral and regulatory dimensions, offering both theoretical insights and practical implications for improving consumer protection in fast paced, interactive digital marketplaces.

Abstract

This community service aimed to enhance mathematics teachers' skills in designing Project-Based Learning (PjBL)to foster students' critical thinking. The workshop, held on October 14, 2023, at SMAN 11 Garut, targeted high school (SMA/SMK) mathematics teachers. Activities included theoretical presentations, hands-on project design, and assessment development. Results showed a significant positive impact on teachers' understanding of PjBL and its link to critical thinking (evidenced by increased pre-test/post-test scores). Teachers also demonstrated improved practical skills in designing relevant math projects and authentic assessments, alongside a heightened awareness of critical thinking's importance. While recognizing potentials and challenges in PjBL implementation, the workshop boosted teacher confidence and motivation. This is a crucial step toward more meaningful math education and developing future-ready critical thinkers, with continued mentoring recommended for sustained impact.

Abstract

Penelitian ini mengevaluasi pelaksanaan program penanganan Penyandang Masalah Kesejahteraan Sosial (PMKS) di Kabupaten Garut. Pendekatan yang digunakan adalah kualitatif deskriptif dengan teknik pengumpulan data melalui wawancara terhadap pelaksana program dan penerima manfaat. Hasil penelitian menunjukkan bahwa pelaksanaan program belum berjalan optimal. Bantuan yang diberikan dinilai belum mencukupi kebutuhan dasar, distribusinya tidak merata, dan belum menjangkau semua pihak yang membutuhkan. Selain itu, masih terdapat kendala dalam pendataan dan kurangnya sosialisasi kepada masyarakat. Program cenderung bersifat bantuan sesaat dan belum menyentuh aspek pemberdayaan. Diperlukan pembenahan dalam sistem pelaksanaan, termasuk perbaikan pendataan, peningkatan koordinasi, dan perubahan pendekatan agar program lebih berdampak dan berkelanjutan bagi kelompok rentan.

Abstract

 Community stewardship can be done directly. Direct interaction is commonly applied, appreciated, and easy to communicate. During the COVID-19 pandemic, direct interaction and visits are almost impossible due to activity limitations and social distancing. Online and semi-online interaction can be applied by inviting community limited representatives combined with the online method. Initiation on online communication is introduced. This project was conducted in companionship and training in Braja Harjosari and Labuhan Ratu VII, East Lampung. Following the introduction of the online and semionline methods, local people can apply and share their knowledge of the new normal paradigm.

Abstract

The need for sustainable alternative energy sources has driven increasing interest in waste heat utilization, particularly from domestic and commercial activities such as cooking stoves. This study analyzes the potential for electrical energy generation from waste heat produced by commercial restaurant stoves using a multi-module thermoelectric generator (TEG) system based on Peltier modules (TEC1-12706 and TEG 1848) equipped with a cooling mechanism. The experimental procedure involved characterizing the electrical performance of the modules under a controlled heat source, followed by direct application to an LPG stove with variations in the distance between the heat source and the module to meet specific temperature conditions. The results demonstrate a strong nonlinear relationship between the temperature difference (delta T) and the output voltage, with optimal performance observed within a delta T range of 40 to 65 degrees Celsius. During stove testing, the system generated a maximum output power of 804 milliwatts at a delta T of approximately 53 degrees Celsius. These findings indicate that the utilization of stove waste heat through serially connected TEG modules combined with active thermal management represents a feasible approach for direct current electricity generation in waste heat recovery applications. However, the overall efficiency remains constrained by internal module resistance and thermal contact instability under real operating conditions.
