Abstract

Axial flux type BLDC motors primary issue is the high operating temperature of the stator and winding components, which can lower system efficiency and hasten the deterioration of the quality of the insulation material. This study is to examine the effects of geometric alterations to the cooling system, such as axial fins on the housing side and curved fins on the casing, on the temperature distribution of a 5-kW axial flux permanent magnet BLDC motor. Convection and conduction heat transport in the cooling system were modeled using ANSYS Fluent software and computational fluid dynamics (CFD) simulation techniques. The Log Mean Temperature Difference (LMTD) and the cooling design's relative efficacy in comparison to the baseline state are the primary metrics that are examined. According to the simulation results, the maximum winding temperature may be lowered to 311 K and the cooling distribution in the rotor, casing, and housing can be improved by adopting curved fin casing and axial fin housing. As the temperature differential between the coolant and the motor surface narrows, the LMTD value drops from the initial condition (5.10 K to 13.94 K), suggesting a more effective heat transfer process. Furthermore, the cooling system's efficiency has more than doubled since its original design. Overall, the study's findings demonstrate that enhancing the cooler's geometric design can increase the BLDC motor's thermal performance and prolong component life.

Abstract

This study discusses the role of Bakawuah Adat as a post-harvest festival in strengthening identity and preserving local culture in Nagari Latang, Sijunjung, West Sumatra. Using descriptive qualitative methods, data were obtained from interviews with traditional leaders, niniak mamak, alim ulama, cadiak pintar, and observations during the 2025 UNP Community Service Program. The results show that Bakawuah Adat is a form of gratitude to Allah SWT for the harvest, as well as a medium for strengthening traditional values ​​and syarak. This tradition involves all elements of the nagari—niniak mamak, bundo kanduang, youth, and children of the nagari—in every traditional procession. In addition to being a ceremony, Bakawuah also serves as a means of character education and cultural inheritance to the younger generation through bajamba activities, art performances, and ancestral grave pilgrimages. The synergy between traditional leaders, the nagari government, and educational institutions ensures that Bakawuah remains sustainable amidst the current of modernization. This tradition is proof that local wisdom can be a stronghold of community identity in the global era.

Abstract

Sampah merupakan permasalahan lingkungan yang hingga kini masih menjadi tantangan besar dalam kehidupan masyarakat, termasuk di pedesaan. Kawasan yang kurang terlayani infrastruktur pengelolaan sampah, masih ditemukan penumpukan sampah yang mengganggu estetika lingkungan, termasuk di lingkungan rumah tangga, pinggiran jalan, dan bahkan di kawasan yang dikelola oleh kelompok swadaya masyarakat. Kabupaten Sijunjung merupakan salah satu kabupaten di provinsi Sumatera Barat yang menghadapi permasalahan dalam hal pengelolaan sampah. Kabupaten Sijunjung memiliki 1 TPA dan kapasistas TPA tersebut masih terbatas. Apabila permasalahan sampah belum menemukan solusi dan belum dapat mencapai titik terang maka jumlah sampah akan terus meningkat jika dalam penanganannya masih belum serius. Pengelolaan sampah merupakan salah satu aspek penting dalam tata kelola lingkungan dan kesehatan masyarakat. KKN UNP Nagari Latang mengusulkan program ecobrik dan plang edukasi sampah sebagai upaya pengelolaan sampah di Nagari Latang. Program ecobrik ini memiliki tujuan untuk mengurangi sampah, memperpanjang umur plastik dan mengubahnya menjadi sesuatu yang bermanfaat.

Abstract

Kebutuhan energi di Indonesia yang terus meningkat menyebabkan ketergantungan tinggi terhadap bahan bakar fosil. Sebagai solusinya, biomassa khususnya sampah organik bisa dimanfaatkan sebagai bahan bakar alternatif terbarukan karena ketersediaannya melimpah. Energi biomassa yang akan dibuat menjadi briket diolah dan dimampatkan sehingga bentuknya lebih teratur dan mempunyai nilai kalor yang tinggi. Melalui proses penekanan dan pemanasan, sampah organik dapat diolah menjadi briket dengan nilai kalor dan efisiensi pembakaran yang lebih tinggi. Penelitian ini bertujuan untuk mengkaji pengolahan sampah organik menjadi briket menggunakan alat press hidrolik, menganalisis pengaruh variasi suhu terhadap karakteristik briket, serta menentukan kandungan proximate dan nilai kalor (Heating Heat Value). Metode yang digunakan adalah eksperimen menggunakan bahan baku sampah organik degan ukuran partikel lewat dari 18 mesh tetapi tidak lewat dari 30 mesh, variasi suhu 200℃, 250℃, dan 300℃ selama 10 menit. Pengujian yang dilakukan yaitu uji thermogravimetric untuk mengetahui kandungan proximate dari briket. Hasil penelitian menunjukkan suhu karbonisasi berpengaruh signifikan terhadap kualitas briket. Suhu 300℃ menghasilkan briket paling optimal dengan nilai kalor tertinggi (23.914 J/g), kandungan volatile terendah, dan fixed carbon tertinggi. Metode kompresi cetak panas menghasilkan briket padat dan kuat tanpa perekat tambahan. Nilai kalor sangat dipengaruhi oleh kandungan volatile dan fixed carbon yang dapat terlihat seiring dengan menurunnya kadar volatile dan meningkatnya fixed carbon. Pengolahan limbah sampah organik menjadi briket bisa menjadi potensi bahan bakar alternatif dengan besarnya Heating Value yang dihasilkan.
