Abstract

Teaching materials available in the field are still minimal and need to be developed. To enhance a more directed learning process, improve student learning outcomes, and increase student independence in learning, it is necessary to develop teaching materials for an independent curriculum. This research aims to develop a scientific-based static fluid practicum module of the independent curriculum. The type of research used is the Research and Development (R&D) using the ADDIE model through the stages of analysis, design, development, implementation, and evaluation. Data collection techniques were feasibility questionnaire, practicality questionnaire and multiple-choice questions for pre-test and post-test. The results of the analysis show that students lack direct observation in learning due to the unavailability of teaching materials that support practicum activities. This research data shows the percentage of the feasibility level of the practicum module which obtained an average of 92.2%, the practicality level of the practicum module obtained an average of 89.9% and the effectiveness level of the practicum module obtained an N-Gain of 0.70. The developed practicum module is feasible, practical, and effective in learning high school physics.

Abstract

Urolithiasis is stone-like material that settles in the urinary tract. The materials that make up urinary stones are calcium oxalate, uric acid, cystine and stuvite. Several medical procedures are often applied to cure this disease. However, many patients choose traditional treatment by consuming herbal medicine. The aim of this research is to show the structure and morphology of uric acid with Orthosiphon Aristatus. This is very important to study as a basis for producing herbal medicines in nanometer sizes. Samples were prepared before characterization.  Urid Acid and Orthosiphon aristatus samples were weighed at a ratio of 0.1: 0.5 milligrams and dissolved in 100 milliliters of Aquabides. The samples were then characterized using XRD and SEM-EDX uric acid crystals mixed with Orthosiphon aristatus undergo progressive dissolution, characterized by an increasingly smooth surface and smaller particle size over time. The particle diameter of each sample changed from 37.64 to 32.83. This research will contribute to urinary stone sufferers choosing appropriate traditional medicine for the type of urinary stone they have

Abstract

This study aims to analyze the improvement of students’ conceptual understanding of energy and wave functions in a three-dimensional particle-in-a-box system through the use of a web-based Schrödinger 3D simulation. This research employed a quantitative approach with a one-group pretest–posttest design involving 20 physics students. The instrument used was a conceptual understanding test administered in the form of pretest and posttest. Data were analyzed using descriptive quantitative analysis and the Normalized Gain calculation. The results showed a significant improvement in students’ understanding. The average pretest score of 5.9 (39.3%) increased to 14 (93.3%) in the posttest. The N-Gain value of 0.89 was categorized as high, indicating that the web-based simulation is highly effective in enhancing students’ conceptual understanding. Based on questionnaire responses, the simulation was found to effectively visualize abstract concepts, increase learning engagement, and facilitate understanding of the relationship between energy, wave functions, and quantum numbers. However, several limitations were identified, particularly in the deeper understanding of wave functions and the need for further feature development. Therefore, the use of a web-based Schrödinger 3D simulation can serve as an effective alternative learning medium to improve students’ conceptual understanding in abstract quantum mechanics topics.

Abstract

This study aims to model the pursuit motion between guided missiles and a circularly moving aircraft using Python-based numerical simulation. The target moves along a circular path with a constant angular speed, while the missile follows a pure pursuit strategy, continuously adjusting its path toward the target's current position. Two scenarios are simulated: single pursuer and multi-agent pursuers. In the single-missile scenario, the missile forms a spiral trajectory and intercepts the target in approximately 4.9 seconds. In the multi-agent configuration, five missiles launched from different vertical positions successfully destroy the target within 8.3 seconds, with the first interception occurring at 6.7 seconds. The model is based on numerical solutions of differential equations governing relative motion dynamics. The results demonstrate that increasing the number of pursuers enhances interception speed and system effectiveness. The study is supported by animations, distance-time graphs, and damage analysis.

Abstract

AbstrakKeterbatasan akurasi alat ukur dan pencatatan manual pertumbuhan balita menghambat validasi data tumbuh kembang di tingkat pelayanan dasar. Pelaksanaan kegiatan Pengabdian kepada Masyarakat (PkM) ini diorientasikan untuk menghilirisasi teknologi berbasis Internet of Things (IoT) melalui implementasi sistem pemantauan tumbuh kembang balita secara digital di Posyandu Melati VII, Kelurahan Bantan, Kecamatan Medan Tembung. Sistem ini mengintegrasikan sensor ultrasonik dan load cell untuk mengukur tinggi serta berat badan balita secara akurat, sekaligus meningkatkan literasi digital kader. Pendekatan partisipatif dipilih sebagai metodologi pelaksanaan kegiatan, di mana alur kerjanya mencakup pemetaan kebutuhan di lapangan, implementasi perangkat di lokasi, pembekalan keterampilan digital, serta pengukuran keberhasilan program. Melalui tahapan implementasi yang dilakukan, integrasi data pengukuran yang berjalan secara otomatis serta terstandardisasi telah berhasil diwujudkan oleh sistem. Hasil PkM menunjukkan peningkatan kapasitas kognitif dan keterampilan mitra secara signifikan. Berdasarkan akumulasi skor total dari tiga domain materi (Teknologi Digital, Sistem Smart Posyandu, dan Pengoperasian Instrumen), rata-rata pemahaman kader melonjak dari 24,7% pada sesi pretest menjadi 85,5% pada sesi posttest. Kenaikan akumulatif ini mencerminkan keberhasilan transfer pengetahuan dan kesiapan psikomotorik kader dalam mengoperasikan perangkat antropometri berbasis IoT secara mandiri. Evaluasi membuktikan digitalisasi ini mengefisienkan pelayanan, memangkas antrean, dan meminimalkan human error. Meskipun terdapat delay pengiriman data dari sensor ke basis data hingga 15 detik (melebihi target 10 detik), karakteristik penundaan ini tidak mengganggu jalannya pelayanan rutin masyarakat. Kondisi tersebut mendukung kelayakan integrasi sistem Smart Health Community melalui antropometri digital yang menjadi solusi tepat guna untuk meningkatkan validitas data kesehatan, mengoptimalkan kinerja kader, dan mendukung keberlanjutan program pemantauan tumbuh kembang anak di Kelurahan Bantan. Keywords: antropometri digital; Internet of Things; kader posyandu; layanan kesehatan; tumbuh kembang balita.AbstratcLimitations in measuring tool accuracy and manual recording of toddler growth hinder the validation of developmental data at the primary care level. This Community Service (PkM) activity is oriented toward downstreaming Internet of Things (IoT)-based technology through the implementation of a digital toddler growth monitoring system at Posyandu Melati VII, Bantan Village, Medan Tembung District. The system integrates ultrasonic and load cell sensors to accurately measure toddlers' height and weight, while simultaneously enhancing the digital literacy of health cadres. A participatory approach was selected as the implementation methodology, with a workflow comprising field needs assessment, on-site device implementation, digital skills training, and program success measurement. Through the executed implementation phases, the system successfully achieved automated andstandardized integration of measurement data. On a non-technical level, the cadres' capacity increased significantly, with average material comprehension rising from 24.7% to 85.5%. Evaluation proves that this digitalization streamlines services, reduces queues, and minimizes human error. Although there is a data transmission delay from the sensors to the database of up to 15 seconds (exceeding the 10-second target), this delay characteristic does not disrupt routine community services. These conditions support the feasibility of integrating a Smart Health Community system through digital anthropometry, providing an appropriate technological solution to improve health data validity, optimize cadre performance, and support the sustainability of child growth monitoring programs in Bantan Village. Keywords: digital anthropometry; Internet of Things; posyandu cadres; health services; toddler growth and development.
