Abstract

Penelitian ini bertujuan untuk menghasilkan prototipe sistem kontrol yang dapat diterapkan pada sistem hibrid menggunakan sinar matahari dan gas LPG untuk menjaga kestabilan dan kelangsungan dengan metode logika fuzzy. Metode yang digunakan meliputi desain kolektor surya, pengantaran gas, desain sistem kontrol menggunakan metode logika fuzzy, uji fungsional, dan uji kinerja. Parameter yang diukur dalam uji pengering melibatkan suhu udara, kecepatan aliran udara, konsumsi energi gas LPG, dan pengurangan berat bahan. Hasil pengukuran digunakan untuk menghitung energi pengeringan, efisiensi pengering, dan kadar air. Dari observasi yang dilakukan pada sistem kontrol logika fuzzy, kadar air sagu berkurang dari 44,17%ww menjadi 6,52%ww setelah dikeringkan selama 4 jam pada suhu stabil 58 0C dengan konsumsi gas LPG sebanyak 0,37 kg. Sementara itu, dengan menggunakan energi surya, kadar air sagu berkurang dari 44,17% wt menjadi 5,69% wt setelah dikeringkan selama 10 jam. Penggunaan daya hibrida memungkinkan penghematan energi, overshoot kecil, dan suhu yang stabil.

Abstract

Blow-by is a condition in which combustion gases from the combustion chamber escape through the piston and piston ring gap into the crankcase. This symptom leads to reduced engine performance, increased fuel consumption, and accelerated component wear. This research aims to analyze the causes of blow-by in the Caterpillar D3K-XL Bulldozer engine and to determine the appropriate troubleshooting steps. The research methods include field study, operator interviews, and direct inspection of engine components such as piston rings, cylinder liners, and valves. The results indicate that the main causes of blow-by are worn piston rings and scratches on the liner wall due to insufficient periodic maintenance. Corrective actions were carried out through replacement of worn components, cleaning, and reassembly according to manufacturer standards. These improvements successfully restored engine performance and minimized the risk of further damage.

Abstract

Error CA559 on the Komatsu PC200-8M0 excavator is an indication of a drop in pressure in the common rail fuel system that can cause combustion failures, decreased engine performance, and increased emissions. This study aims to analyze the main causes of CA559 errors through a thorough evaluation of the condition of the fuel system, especially the injector components. The research methods include field observation, operator interviews, visual examinations, cut-out tests, as well as return flow measurements of injectors and supply pumps based on manufacturer's standards. The measurement results showed that the number 6 cylinder injector had a return flow value of 500 cc/min, far exceeding the standard limit of 180 cc/min, indicating a significant internal leakage. This condition causes unstable rail pressure, incomplete combustion, engine vibration, and the appearance of black smoke. Evaluation of other components such as inlet pressure, pressure limiter, and return supply pump shows that the results are still within normal limits. Thus, it can be concluded that the main cause of the CA559 error is an internal leak in injector number 6. Replacement of injectors and improved fuel quality control are recommended to prevent the recurrence of similar disturbances.
