Abstract

Boundary layer adalah lapisan batas yang terbentuk akibat gesekan antara permukaan penampang dan fluida, sehingga terjadi gradiensi kecepatan. Penelitian ini mengamati gradiensi kecepatan fluida pada boundary layer dalam pipa lurus menggunakan metode eksperimental. Distribusi kecepatan fluida diukur menggunakan pipa akrilik berdiameter 1” dan jarum tumpul berdiameter 1,5 mm yang menyerupai tabung pitot dengan sistem perbedaan tekanan stagnasi dan tekanan statis. Fluida dengan berbagai viskositas dan laju aliran diuji untuk memahami pengaruhnya terhadap karakteristik lapisan batas. Dengan flowrate 10 liter/menit menunjukkan hasil pengukuran kecepatan fluida meningkat seiring bertambahnya jarak radial pada dinding pipa mulai dari =2 mm (0,334 m/s), =5,5 mm (0,341 m/s), =7,5 mm (0,425 m/s), =10,5 mm (0,438 m/s), dan pada =12,7mm (0,443 m/s). Kecepatan tertinggi tercatat di titik tengah pipa yang membuktikkan bahwa hasilnya sesuai dengan karakteristik boundary layer, di mana gaya gesekan dan viskositas berkurang.

Abstract

Traditional batik enterprises in Indonesia face major challenges in sustaining productivity, efficiency, and global competitiveness. One key issue is the manual filtering of batik wax (malam), which often causes clogging and solidification, disrupting production and reducing batik quality. This research introduces an Automatic Anti-Clog Batik Wax Filtering Technology as an innovative solution for revitalizing sustainable batik entrepreneurship, registered under Industrial Design Intellectual Property IDD000075738. The study aims to develop a practical technology that automatically filters batik wax, maintains an ideal temperature, and prevents freezing during the production process. This innovation is expected to improve production efficiency, maintain motif quality, and enhance the resilience of small and micro batik enterprises. The research adopts a Research and Development (R&D) approach through applied experimentation, engineering design, and co-creation with local batik artisans. The two-year project includes wax characterization, temperature analysis, prototype design, and field testing with Keyna Gallery, a natural dye batik producer in Jombang. The outcomes include a simple patent, a functional prototype, and international journal publications. With a targeted Technology Readiness Level (TRL) of 7–9, this innovation supports SDG 8 (Decent Work and Economic Growth) and SDG 12 (Responsible Consumption and Production), promoting a sustainable, efficient, and globally competitive batik industry.

Abstract

Penelitian ini mengkaji pemilihan material pada pemotong kertas manual kapasitas besar melalui pendekatan berbasis literatur dan data sekunder, dengan mengacu pada konfigurasi umum produk yang telah tersedia di pasaran. Fokus diarahkan pada analisis karakteristik teknis material dua komponen utama—pisau dan rangka—guna merumuskan rekomendasi desain produk lokal yang efisien, andal, dan tetap ekonomis. Analisis difokuskan pada perbandingan teknis material secara komparatif dan evaluasi multi-kriteria melalui weighted decision matrix. Hasil menunjukkan bahwa material seperti baja perkakas D2 dan SKD11, serta baja paduan rendah solid, memberikan performa unggul pada produk profesional, namun tidak efisien secara biaya untuk skala UMKM. Alternatif material seperti SK5 untuk pisau dan AISI 1020 untuk rangka dinilai mampu memberikan kompromi optimal antara performa teknis dan efisiensi biaya, dengan tetap mempertimbangkan ketersediaan lokal dan kemudahan manufaktur. Kajian ini memberikan kontribusi terhadap perancangan ulang pemotong kertas berbasis prinsip rekayasa material yang adaptif terhadap kebutuhan industri nasional skala kecil dan menengah.

Abstract

General Background: Centrifugal pumps are widely applied in industrial cooling systems where bearing reliability determines operational continuity. Specific Background: At PT Java Pacific, a between bearing centrifugal pump using type 6311 deep groove ball bearing operates for gearbox cooling and frequently experiences premature failure. Knowledge Gap: A discrepancy exists between theoretical bearing life estimation and actual service life in field operation, yet quantitative comparison in this specific configuration remains limited. Aims: This study aims to calculate the theoretical L10h bearing life, compare it with actual operational data, and formulate an appropriate preventive maintenance strategy. Results: Based on a basic dynamic load rating of 74.1 kN, equivalent load of 5.45 kN, and shaft speed of 5000 rpm, the calculated bearing life is 8,378.07 hours (0.96 years). However, field data show replacement intervals of only 5–8 months, indicating earlier degradation primarily associated with lubrication and operational factors. Novelty: This study provides a direct quantitative comparison between theoretical bearing life and real industrial data for a 6311 bearing in a between bearing centrifugal pump configuration. Implications: The findings support structured lubrication scheduling and condition monitoring to reduce premature bearing failure and optimize maintenance planning in industrial pump systems. Keywords: Centrifugal Pump, Bearing Life, Preventive Maintenance, Equivalent Load, Industrial Reliability Key Findings Highlights Theoretical L10h calculation produced 8,378.07 operating hours under specified load and speed conditions. Field replacement records indicate shorter service intervals of 5–8 months. Lubrication management and operational load control are critical factors in reducing premature failure.

Abstract

General Background Catfish cultivation is a major freshwater aquaculture activity widely practiced in Indonesia, particularly in urban areas with limited land availability. Specific Background The bucket-based aquaculture system (budidamber) provides a compact solution, yet requires frequent water quality monitoring and maintenance. Knowledge Gap Manual water control often leads to delayed maintenance due to farmers’ time constraints, reducing water quality and affecting fish survival. Aims This study aims to design and implement a semi-automatic IoT-based system for monitoring and controlling water quality in bucket catfish cultivation. Results The system utilizes ESP32, temperature sensor DS18B20, ultrasonic sensor, and Telegram-based control, achieving an average water temperature of 28.9°C within the acceptable standard range and enabling automated water drainage with an average delay of 11 seconds and deviation of 4%. Novelty The integration of real-time monitoring, automated drainage scheduling, and remote control via Telegram provides a practical semi-automatic solution for small-scale aquaculture. Implications This system supports efficient time management for farmers and improves water quality control, contributing to sustainable small-scale aquaculture practices in limited-space environments. Keywords: Internet of Things, Budidamber, Water Quality Monitoring, ESP32, Aquaculture System Key Findings Highlights Remote monitoring system maintains stable water conditions within standard limits Automated drainage operates with minor delay under real conditions Integrated messaging control simplifies operational management for farmers
