Abstract

Reliability Centered Maintenance (RCM) merupakan suatu proses untuk bisa menentukan jenis pemeliharaan yang sesuai dalam konteks operasi dan konsekuensi kegagalan untuk masing-masing asset pada mesin produksi. mesin Ripple Mill adalah salah satu mesin produksi yang berfungsi sebagai pemecah biji sawit untuk memisahkan cangkang dengan inti sawit. Kegagalan pada mesin Ripple Mill menghambat jalannya proses produksi yang berdampak pada penurunan kapasitas produksi. Penelitian ini dilakukan untuk mengidentifikasi Failure Mode Effect Analysis (FMEA) dan Logic Tree Analysis (LTA) dan menghitung failure rate dari mesin Ripple Mill. Berdasarkan analisis Failure Mode Effect Analysis (FMEA) mengidentifikasi 17 Failure mode dengan kegagalan mechanical sebesar 35,30 %, Electrical 29,40 % dan Instrumentation 35,30 %. Hasil Logic Tree Analysis dari total 17 failure mode menunjukkan bahwa 0% kategori A, 11,76 % diantaranya adalah kategori B, 35,29 % kategori C, 23,52 % kategori D/B dan 29,41 % kategori D/C. Hasil regression interval waktu kerusakan dari masing-masing mesin Ripple Mill, Ripple Mill 3 tahun 2014 nilai bheta adalah 0,32057658 dan Ripple Mill 3 tahun 2015 nilai bheta sebesar 0,149883 < 1 dan nilai betha Ripple Mill 4 tahun 2014 adalah 0,0286688 sedangkan Ripple Mill 4 tahun 2015 adalah sebesar 0,065800367 < 1, maka laju kegagalan akan berkurang seiring bertambahnya waktu, Jadi pemeliharaan yang di gunakan adalah Predictive maintenance yang merupakan perawatan tingkat sedang dilaksanakan untuk mengembalikan dan memulihkan sistem dalam keadaan siap dengan memberikan perbaikan atas kerusakan yang telah menyebabkan merosotnya tingkat keandalan.

Abstract

Motorcycles are the most in demand vehicles in Indonesia. The number of users of these two-wheeled vehicles continues to increase every year. However, the increasing number of motor vehicles is also accompanied by increasing crimes against motorcycle users. To solve the problem, it is designed a security tool on motorcycles that can turn motorcycles on and off using voice commands based on arduino uno r3 connected to bluetooth on smartphones. It aims to tackle and reduce the number of crimes against motorcycle users.

Abstract

The development of automotive technology is very fast, we can find this in today's vehicles that use a lot of very sophisticated technology, namely in terms of engines, electricity, and its newest features, especially on two-wheeled vehicles. Therefore, the user community is required to be more selective in choosing a vehicle both in terms of quality and quantity. Including in the selection of spare parts on vehicle engines must use good quality, this is useful as a motorbike power booster, especially in the ignition system, namely spark plugs as a vital tool that sprinkles sparks in the combustion chamber. Recently, many spark plugs have been found that are not good enough so that the power generated by the vehicle is reduced. The purpose of this test is as a Comparative Test of the Endurance of Various Motorcycle Spark Plugs by Using a Spark Plug Tester so that it can be seen that the spark plug is suitable or not used in the vehicle which aims to get maximum performance.

Abstract

Noise on a motorcycle is unwanted sound because it does not fit the context of space and time thus affecting ride comfort . Noise caused by the vibrating object or objects collide . Which became the main object causes of noise in the Cylinder Head Honda cb 150 R is due to the large gap camshaft causing collision between the camshaft with holder. This research was conducted entirely in the workshop by examining the influence of several variations of the gap camshaft to noise generated in the cylinder head . Variations slit used was 0,75 mm , 0,85 mm , 0,95 mm , 1,05 mm, and 1,15 mm . The results showed that the variation of the gap camshaft significant effect on the noise generated , namely : a gap of 0,75 mm camshaft generate noise by 78,12 dB , 0,85 mm gap camshaft generate noise with a value of 78,37 dB , 0,95 mm gap camshaft generate noise 78,93 dB , 1,05 mm gap camshaft generate noise levels at 79,95 dB, and 1,15 mm gap camshafts produce 80,23 dB. Based on the results of the research with camshaft gap variation can be concluded that the lowest noise level generated by the camshaft gap of 0,75 mm .

Abstract

Fungsi rem pada kendaraan adalah untuk membatasi gerakan pada komponen rem yang bertujuan untuk memperlambat serta menghentikan roda penggerak sehingga kendaraan jadi berhenti. Penelitian ini menggunakan metode Failure Mode Effect Analisis ( FMEA ) untuk mengetahui penyebab kegagalan pada system pengereman kendaraan berat jenis mobil trailer, hasil analisis perhitungan nilai FMEA dengan RPN (Risk Priority Number) di dapatkan 2 componen pneumatik yang paling sering mengalami kegagalan yaitu Componen Control valve trailer brake sebesar 189, dan component Chamber Brake 147, hasil analisis dengan menggunakan FTA(Fault Tree Analysis) faktor yang mempengaruhi kegagalan pada komponen pneumatik brake system adalah faktor manusia & mesin.
