Abstract

The lightweight design of the rocket motor tube is a critical requirement for enhancing the rocket's flight performance. This study assesses the impact of wall thickness, cap thickness, and fillet radius on structural strength and the optimization of rocket motor tube weight using the finite element method with the assistance of Ansys software. A total of 12 finite element model variations, utilizing Aluminium 6061-T6, were developed and subjected to a uniform internal operating pressure load of 10 MPa. The design includes wall thickness variations of 8 and 10 mm, cap thickness options of 25 and 30 mm, and fillet radius dimensions of 20, 25, and 30 mm, allowing for a comprehensive comparison to achieve the required minimum safety factor while minimizing structural weight. The research concludes that increasing the fillet radius is a more recommended approach compared to increasing wall thickness and cap thickness. The results indicate that Model 9, with wall thickness, cap thickness, and fillet radius dimensions of 10 mm, 25 mm, and 30 mm, respectively, is the optimal choice due to its lightweight construction.

Abstract

The main landing gear is one of the important components in UAV aircraft. This paper aims to analyze the natural frequency of the main landing gear and determine its normal mode shape. This analysis is important so that no resonance causes damage to the main landing gear components. The main landing gear uses Aluminum 6061 material and the analysis is carried out using the finite element method with the help of Ansys Workbench software. The analysis showed that the natural main landing gear frequencies for mode 1 to mode 6 were 76.04 Hz, 85.07 Hz, 167.82 Hz, 201.92 Hz, 288.39 Hz, and 327.00 Hz, respectively. The maximum deformation of the main landing gear for mode 1 to mode 6 is 33.73 mm, 35.35 mm, 48.16 mm, 44.62 mm, 38.14 mm, and 41.51 mm, respectively.

Abstract

This research discusses research that focuses on the capabilities of satellitebased LoRa, for satellite positions orbiting in low earth orbit (LEO). The expectation of low power wide area network (LPWAN) satellite can find the quality of transmitting data using LoRaWAN which is part of LPWAN and can provide quality of service (QoS) with high-quality real-time sensor data, low latency, long-range, low-power, no attenuation signal, no problem with obstacles in terrestrial areas, and other benefits that can be widely optimized. This article uses a comprehensive analysis of mathematical calculations as well as precise and accurate simulations for the actual development of satellite-based LPWAN. The satellite-based IoT is unlimited in terms of distance, to provide good services to all IoT users in the world. The comparison with terrestrial measurements is analyzed in detail, especially the signal attenuation factor that causes a lot of signal loss and data is not well received. Several methods are used to help reduce collision data, such as adaptive data rate (ADR) which can reduce collisions by 30%.

Abstract

Kajian literatur ini menelaah efektivitas penerapan Problem Based Learning (PBL) dalam pembelajaran Biologi di tingkat Sekolah Menengah Atas (SMA) berdasarkan 22 artikel penelitian periode 2021–2025. Fokus kajian mencakup dua domain utama, yaitu literasi sains (pemahaman konsep, keterampilan proses sains, berpikir kritis) dan sikap terhadap Biologi (motivasi, minat, keterlibatan). Analisis tematik dan deskriptif menunjukkan bahwa PBL secara konsisten meningkatkan hasil belajar kognitif, afektif, dan psikomotor siswa. Domain literasi sains menunjukkan peningkatan signifikan dengan kategori tinggi dan sangat tinggi mencapai 63%, sedangkan domain sikap terhadap Biologi mencapai 77%. PBL mendorong siswa membangun pengetahuan secara aktif melalui pemecahan masalah kontekstual, kerja kelompok, dan diskusi terbimbing. Efektivitas PBL dipengaruhi kesiapan guru, pengelolaan waktu, serta pemanfaatan media pembelajaran. Kajian ini menegaskan hubungan sirkular antara literasi sains dan sikap positif, di mana keterlibatan aktif memperkuat penguasaan konsep dan berpikir ilmiah, sementara literasi sains menumbuhkan sikap positif terhadap pembelajaran. Disarankan agar PBL diterapkan secara terstruktur dengan dukungan media interaktif, pelatihan guru, dan evaluasi berkelanjutan untuk memperkuat kompetensi abad ke-21 siswa. Hasil kajian ini memberikan dasar empiris bagi pengembangan strategi pembelajaran aktif dan kontekstual dalam pembelajaran Biologi.

Abstract

Kajian ini bertujuan untuk menganalisis pengaruh penggunaan pupuk organik terhadap pertumbuhan tanaman jahe (Zingiber officinale Rosc.) berdasarkan hasil-hasil penelitian yang telah dipublikasikan. Metode yang digunakan adalah Systematic Literature Review (SLR) dengan menelaah 16 artikel ilmiah yang diterbitkan antara tahun 2018–2025. Sumber literatur diperoleh dari basis data Google Scholar, Science Direct, dan DOAJ dengan kata kunci “pupuk organik”, “jahe”, dan “Zingiber officinale”. Parameter yang dikaji meliputi tinggi tanaman, jumlah daun, jumlah anakan, dan berat rimpang. Hasil sintesis menunjukkan bahwa aplikasi pupuk organik, baik padat maupun cair, secara konsisten meningkatkan pertumbuhan vegetatif dan hasil jahe dibandingkan tanpa pupuk. Pupuk kandang sapi, kambing, ayam, serta kascing memberikan pengaruh positif terhadap tinggi tanaman dan berat rimpang, sedangkan pupuk organik cair berbahan dasar urin sapi, kulit pisang, dan tandan kosong kelapa sawit mampu meningkatkan jumlah anakan dan aktivitas fisiologis tanaman. Kombinasi pupuk organik, pupuk hayati dan anorganik juga menghasilkan pertumbuhan terbaik dengan peningkatan berat rimpang hingga lebih dari 60 g per tanaman. Secara keseluruhan, pupuk organik berperan penting dalam memperbaiki kesuburan tanah, meningkatkan efisiensi penyerapan unsur hara, serta mendukung sistem budidaya jahe yang berkelanjutan dan ramah lingkungan. Diperlukan penelitian lanjutan untuk menentukan jenis dan dosis pupuk organik yang paling sesuai dengan kondisi lahan dan varietas jahe di berbagai wilayah Indonesia.

Abstract

This study is a systematic literature review examining the effectiveness of 3D printing integrated with Augmented Reality (AR) in Biology education. Thirteen peer-reviewed articles published between 2017 and 2025 were analyzed to evaluate three main aspects: learning effectiveness, 3D product development, and improvement in student learning outcomes or motivation. The findings indicate that 3D printing combined with AR consistently enhances conceptual understanding, technical skills, and student motivation, with reported effectiveness ranging from 49% to 90%. The learning products developed include cell models, DNA/RNA molecules, anatomical organs, flower models, and tactile tools for students with special needs, using software such as Blender, Tinkercad, and Ultimaker Cura, as well as PLA or recycled filaments. Improvements in learning outcomes were observed across cognitive, affective, and psychomotor domains, with average gains ranging from 20% to 83% across studies. This review confirms that integrating 3D printing with AR enriches learning experiences, promotes inclusive education, and enhances technological literacy in Biology. Future research is recommended to employ randomized experimental designs, standardize effectiveness metrics, and conduct long-term evaluations to assess knowledge retention and motivational impact more comprehensively.
