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.
