Pengaruh Kecepatan Treadmill terhadap Parameter Kinematika Berjalan: Studi Kasus pada Kecepatan 2,0; 2,5; dan 3,0 km/jam

Penelitian tentang biomekanika gerak berjalan manusia memiliki posisi yang sangat penting di berbagai bidang. salah satunya adalah rehabilitasi, atletik, dan pembuatan kaki prostetik. Fokus dari penelitian ini untuk menganalisis tentang pengaruh variasi kecepatan pada treadmill terhadap parameter kinematika berjalan manusia seperti frekuensi, durasi langkah serta kecepatan dan percepatan sudut. Variasi kecepatan treadmill yang digunakan adalah 2,0; 2,5; dan 3,0 km/jam. Penelitian ini menggunakan desain studi kasus eksploratif (Single-subject case study) untuk mengevaluasi kelayakan dari sistem motion capture dengan menggunakan software Blender dan kamera GoPro Hero 9. Selanjutnya data akan dianalisa menggunakan MATLAB untuk mengetahui frekuensi, durasi langkah, serta kecepatan dan percepatan sudut setiap segmen sendi pada tubuh bagian bawah. Hasil menunjukkan bahwa peningkatan kecepatan treadmill menyebabkan durasi siklus berjalan yang lebih pendek, peningkatan frekuensi langkah, serta peningkatan kecepatan dan percepatan sudut segmen tubuh. Temuan ini memberikan wawasan tentang mekanisme adaptasi pola gerakan berjalan manusia dan kaitannya dalam rehabilitasi serta pelatihan atletik. Studi lebih lanjut sebaiknya mencakup jumlah partisipan yang lebih banyak dan mempertimbangkan faktor tambahan berupa gaya reaksi tanah untuk analisis yang lebih menyeluruh

Analisis Struktur Rangka Box Fermentasi Biji Kakao Menggunakan Metode Elemen Hingga

Proses fermentasi biji kakao di Kabupaten Berau oleh para petani masih dilakukan secara tradisional. Metode ini menggunakan kotak fermentasi berbahan kayu yang berpotensi menyebabkan kontaminasi akibat korosi dari paku atau material lainnya, sehingga berdampak pada keamanan dan kualitas biji kakao yang dihasilkan. Kebutuhan akan teknologi fermentasi yang lebih efisien mendorong pengembangan desain rangka fermentasi yang kuat dan aman.  Penelitian ini bertujuan untuk menganalisis kekuatan desain rangka fermentasi berbahan ASTM A36 menggunakan metode elemen hingga (FEA) pada perangkat lunak Autodesk Inventor Professional 2024. Analisis mencakup distribusi tegangan (Von Mises), perpindahan (Displacement), dan faktor keamanan (Safety factor). Proses penelitian diawali dengan pembuatan desain rangka dan penentuan dimensinya, kemudian dilanjutkan dengan analisis elemen hingga menggunakan pembebanan sebesar 637 N. Simulasi dilakukan untuk menentukan distribusi tegangan maksimum, nilai perpindahan, dan faktor keamanan guna memastikan bahwa desain memenuhi standar keamanan.  Hasil simulasi menunjukkan tegangan maksimum Von Mises sebesar 7,19443 MPa, perpindahan (Displacement) sebesar 0,0693914 mm, dan faktor keamanan (Safety factor) sebesar 15. Berdasarkan hasil tersebut, desain rangka yang telah dianalisis secara teknis dinyatakan aman untuk menahan beban statis maupun beban kejut. Penelitian ini memiliki kebaruan dalam penerapan material ASTM A36 dan analisis FEA untuk menghasilkan desain rangka box fermentasi yang lebih efisien secara struktur dan memiliki faktor keamanan lebih baik dibandingkan model konvensional menggunakan material kayu

Analisis Beban Pendinginan Kereta Argo Lawu New Generation Menggunakan Metode Cooling Load Temperature Difference (CLTD)

Kereta Argo Lawu New Generation adalah salah satu layanan transportasi kereta api yang dioperasikan oleh PT Kereta Api Indonesia (KAI) untuk rute Solo Balapan - Gambir. Kenyamanan termal penumpang menjadi aspek penting dalam layanan ini, mengingat fluktuasi suhu eksternal yang signifikan. Sistem pendingin udara (AC) pada kereta harus mampu menjaga suhu yang nyaman selama perjalanan. Namun, perhitungan beban pendinginan yang akurat diperlukan untuk memastikan kapasitas sistem pendingin sesuai dengan kebutuhan termal dalam gerbong. Penelitian ini menggunakan metode Cooling Load Temperature Difference (CLTD) untuk menganalisis kebutuhan beban pendinginan pada Kereta Argo Lawu New Generation. Perhitungan dilakukan dengan mempertimbangkan faktor eksternal (radiasi matahari, suhu lingkungan) serta faktor internal (jumlah penumpang, peralatan elektronik, dan pencahayaan). Data yang dikumpulkan meliputi spesifikasi material gerbong, kapasitas pendinginan AC, serta parameter lingkungan seperti suhu dan kelembapan. Hasil perhitungan menunjukkan bahwa total beban pendinginan yang diperlukan adalah 37814,93 kkal/jam, sementara kapasitas AC yang tersedia sebesar 40000 kkal/jam. Hal ini mengindikasikan bahwa sistem pendingin yang terpasang masih mampu menjaga suhu dalam batas kenyamanan termal. Kesimpulan dari penelitian ini adalah bahwa metode CLTD dapat digunakan secara efektif dalam perhitungan beban pendinginan kereta api dan dapat dijadikan acuan dalam perancangan sistem pendingin transportasi massal lainnya

Pengaruh Debit Aliran Air terhadap Efektivitas Pendinginan Evaporatif dengan Cooling Pad Berbahan Sabut Kelapa dan Tapis Lontar

Krisis energi dan perubahan iklim meningkatkan konsumsi energi untuk pemanasan, pendinginan, dan ventilasi, dengan sektor ini menyumbang 33% dari konsumsi energi global. Pendinginan udara mencapai 60% dari permintaan listrik musim panas, sehingga konservasi energi penting. Sistem pendinginan evaporatif dengan cooling pad berbahan sabut kelapa dan tapis lontar menjadi solusi yang efektif. Tujuan penelitian ini adalah untuk menganalisis pengaruh variasi debit aliran air pada cooling pad berbahan sabut kelapa dan tapis lontar terhadap efektivitas pendinginan evaporatif. Penelitian ini dilakukan secara eksperimen pada ruang pendingin evaporatif dengan dimensi 2,44 m x 1,22 m x 1,22 m dengan merubah jenis bahan cooling pad dan variasi debit aliran air 5 lpm, 7 lpm, dan 9 lpm. Berdasarkan hasil penelitian variasi debit aliran air memiliki pengaruh terhadap efektivitas pendinginan evaporatif menggunakan cooling pad berbahan sabut kelapa dan tapis lontar. Peningkatan debit air dari 5 lpm hingga 9 lpm menghasilkan penurunan temperatur yang lebih besar di ruang pendingin, terutama di ruang 1 yang dekat cooling pad, dan meningkatkan kelembaban relatif di ruang pendingin. Cooling pad sabut kelapa menunjukkan penurunan temperatur awal di ruang satu dekat cooling pad , sementara tapis lontar memberikan distribusi pendinginan yang lebih merata dan konsisten di ruang 1 maupun ruang 2 yang lebih jauh dari cooling pad sehingga tapis lontar menjadi bahan cooling pad yang memiliki performa yang lebih baik dibandingkan sabut kelapa

The Effectiveness of Mechanical Power on An Auxiliary Rotor in The Design of Counter Rotating Wind Turbine (CRWT)

The counter-rotating wind turbine (CRWT) represents a novel development in horizontal-axis wind turbine technology. This innovative design incorporates an additional rotor that rotates in unison with the main rotor along the same axis. Without the supplementary rotor, the turbine's configuration is analogous to that of a horizontal-axis wind turbine (HAWT) with the main rotor functioning independently. The primary objective of this study is to undertake a comparative analysis of the effectiveness of mechanical energy generation, as measured by torque, between the CRWT and HAWT designs. The configuration of the wind turbine is situated within a wind tunnel, characterized by a rectangular cross-section. The testing of wind turbines has been conducted at wind velocity of 2 m/s, 3 m/s, and 4.5 m/s. The total mechanical power measured was 0.14 W, 0.21 W, and 0.28 W at wind velocity of 2 m/s, 3 m/s, and 4.5 m/s, respectively. The final results of the study have analyzed the effectiveness of power enhancement through power coefficients
