Abstract

The incorporation of wood dust and crumb rubber waste as filler in polymer matrix composite still requires in-depth evaluation of mechanical properties because they have different characteristics. This study evaluates the tensile, flexural, and hardness properties of epoxy composites reinforced with various fractions of wood dust and crumb rubber (5, 10, and 15%). The results showed that the composite with 5% crumb rubber produced the highest tensile strength of 15.52 MPa (CR5), while the highest flexural strength was 30.46 MPa (CR10), and the highest hardness was 75.9 HRC (CR15), indicating superior performance for CR fillers. The observations of the fracture surface showed that increasing the fraction of wood dust contributed to lowering the mechanical performance due to the relatively large distribution of voids and agglomeration. This finding confirms the importance of filler type and fraction selection on composite performance. Future research is recommended to explore filler surface modification and hybrid combinations to improve dispersion and bonding between phases in composites.

Abstract

The present study investigates the impact of particle size variation (10, 18, 20, and 35 mesh) on the physical and thermal properties of charcoal briquettes from coconut shells manufactured with a screw-based extruder machine. The briquette manufacturing process involves crushing, mixing, molding, and drying. Assessments were conducted to ascertain friability, compressive strength, density, calorific value, volatile matter, ash content, fixed carbon, and water content. Comparable assessments were also performed on commercially available export-grade briquettes designated as b_5. The results of this investigation demonstrate that all briquette samples generated conform to the SNI 01-6235-2000 standard for water, ash, and calorific value, and adhere to international standards for fixed carbon, density, and compressive strength. The b_4 specimen (35 mesh) demonstrated the best performance, exhibiting a friability of 0% in the unburned condition and 7.04% in the burned condition. Compared to b_5, the b_4 specimen exhibited notable enhancement, demonstrating a 100% increase in friability in the unburned condition and a 53.22% improvement in the burned condition. This study emphasizes the significance of smaller particle sizes in improving briquettes' mechanical strength and combustion efficiency. It presents the importance of renewable energy technology and sustainable waste management.

Abstract

Krisis energi akibat menurunnya ketersediaan bahan bakar fosil mendorong pengembangan kendaraan hemat energi, salah satunya melalui upaya pengurangan rolling resistance pada ban kendaraan Urate Evo-7. Penelitian ini bertujuan untuk menganalisis pengaruh variasi tekanan ban terhadap waktu akselerasi, jarak gelincir, dan efisiensi konsumsi bahan bakar. Metode penelitian yang digunakan adalah eksperimental dengan variasi tekanan ban sebesar 55 psi, 65 psi, 75 psi, dan 85 psi. Pengujian dilakukan di Sirkuit Mijen Semarang sepanjang 2,7 km dengan empat kali percobaan pada setiap variasi tekanan ban. Parameter yang diamati meliputi waktu tempuh satu lap, jarak gelincir kendaraan dari kecepatan 32 km/jam hingga berhenti tanpa pengereman, serta konsumsi bahan bakar yang diukur menggunakan buret, stopwatch dan pita ukur, kemudian dianalisi secara deskriptif dan komparatif. Tekanan ban 85 psi menghasilkan jarak gelincir rata-rata sepanjang 778 meter dan konsumsi bahan bakar rata-rata  18 ml dengan efisiensi mencapai 450 km/l. Kendaraan Pandawa Team dapat meningkat sebesar 34,5% dibandingkan tekanan ban 55Psi. Diikuti pengurangan waktu saat berakselerasi sebesar 10,6 % dan jarak gelincir saat mesin dimatikan mengalami peningkatan 17,5%. Secara keseluruhan, hal ini didasari perbedaan tekanan ban pada kendaraan, sehingga nilai rolling resistance menurun akibat dari tekanan ban yang lebih besar. Penelitian ini diharapkan dapat menjadi referensi dalam pengembangan kendaraan hemat energi berbasis optimasi tekanan ban.

Abstract

Pertumbuhan jumlah penduduk di Indonesia yang terus meningkat berdampak pada semakin menipisnya ketersediaan bahan bakar fosil. Seiring dengan kondisi tersebut, pengembangan sumber energi alternatif pun semakin berkembang, salah satunya adalah briket biomassa. Briket biomassa merupakan salah satu bentuk energi terbarukan yang dapat dimanfaatkan sebagai pengganti bahan bakar minyak. Namun demikian, proses produksi briket biomassa umumnya masih dilakukan secara manual karena penelitian dan pengembangan terhadap alat pemotong briket otomatis masih terbatas. Beberapa studi sebelumnya telah merancang alat pemotong briket otomatis berbasis mikrokontroler Arduino  dengan tingkat konsistensi sebesar 77,5% hingga 90,7%. Penelitian ini bertujuan untuk menganalisis kinerja serta mengembangkan alat pemotong briket otomatis berbasis sistem pneumatika dengan variasi kadar air pada adonan briket sebagai variabel. Parameter yang dikaji meliputi tingkat konsistensi dan produktivitas alat pemotong briket otomatis tersebut. Hasil pengujian menunjukkan bahwa konsistensi tertinggi sebesar 91,6% dan produktivitas sebesar 68,1% diperoleh pada pengujian ketiga dengan kadar air adonan sebesar 46,9%. Kinerja alat ini masih dapat ditingkatkan melalui penyesuaian kecepatan pada mesin screw extruder, modifikasi pada bidang miring tempat jatuhnya briket, serta optimalisasi bahan campuran adonan briket.

Abstract

Abstrak Penelitian ini bertujuan untuk merancang dan merealisasikan alat uji Macro Thermogravimetric analysis (TGA) berbasis oven microwave sebagai solusi alternatif terhadap alat TGA konvensional yang mahal dan kompleks. Alat ini mengintegrasikan komponen utama seperti oven microwave termodifikasi, sensor suhu thermocouple tipe K, load cell digital, dan mikrokontroler Arduino Mega 2560, yang mampu memantau perubahan suhu dan massa secara real-time. Proses perancangan menggunakan pendekatan metode Pahl and Beitz yang meliputi tahap perencanaan spesifikasi, perancangan konseptual, perancangan bodi, hingga pembuatan prototipe. Hasil pengujian menunjukkan bahwa alat ini mampu mereproduksi kurva termogravimetri dengan akurasi tinggi, stabilitas suhu <±5°C, serta kehilangan massa yang terukur presisi hingga 84,20% pada suhu 425°C. Desain ini terbukti efisien, ekonomis, dan layak diaplikasikan dalam pendidikan teknik, praktikum mahasiswa, serta riset awal berbasis proyek mandiri.

Abstract

Learning batik motif design at Vocational High Schools requires learning media that can facilitate conceptual understanding visually and interactively in accordance with students’ characteristics. However, the use of interactive learning media that supports the​ improvement of students’cognitive abilities at SMKN 3 Pekalongan is still limited. This study aims to develop interactive learning media using Genially and to analyze its effectiveness in improving students’ cognitive abilities in traditional and contemporary batik elements at SMKN 3 Pekalongan. This study employed a Research and Development (R&D) method using the ADDIE model. The research subjects consisted of 61 eleventh-grade KKBT students, who were divided into an experimental class and a control class to examine the effectiveness of the developed learning media. The efectiveness test showed an increase in the learning outcomes in the experimental class from 74.45 to 89.55, with N-gain value 0.657 (moderate category), while the control class obtained an N-gain of 0.21 (low category). The Independent Sample Test results indicated a significant difference in learning outcomes between the experimental class and the control class. Therefore, the Genially-based interactive learning media is declared feasible, practical, and effective for use in learning.

Abstract

This study evaluates the performance of pressure nozzle type spray dryer. Maximum evaporation capacity was tested using water under various nozzle air pressures, airflow rates and at two inlet air temperatures. Solution of biancaea sappan extract mixed with maltodextrin were used to analyze powder yield, wall deposition, color of the powder, and efficiency of the spray dryer. An increase of nozzle air pressure and airflow rate gives finer atomization resulting in higher heat transfer. Combined with an increase in inlet air temperature, maximum evaporation capacity is achieved and can increase the powder yield of the spray dryer due to better moisture removal. Significant wall deposition was found in the head, drying chamber and cyclone duct. Visual analysis of the powder indicated that higher temperatures and prolonged residence time advanced the Maillard reaction, darkening the powder and could degrade its texture. A rather significant amount of powder loss was observed which is likely caused by fine particles leaving with exhaust air.
