Abstract

ABSTRAKKondisi ketidakselarasan sistem transmisi pulley-belt pada mesin bubut berpengaruh terhadap nilai inefisiensi konsumsi energi mesin perkakas. Penelitian ini bertujuan untuk melakukan kajian evaluasi kinerja efisiensi energi mesin bubut pada kondisi sistem transmisi pulley-belt mesin yang selaras dan tidak selaras. Kajian ini menggunakan metoda penilaian indikasi specific energy consumption (SEC) dari proses pemesinan bubut. Nilai total konsumsi energi saat proses pemotongan diukur menggunakan power analyzer, dan diolah menjadi nilai data SEC, kemudian dianalisis menggunakan Data Envelopment Analysis untuk mendapatkan harga referensi. Penilaian skor penurunan energi setiap mesin diperoleh dengan membandingkan jarak nilai SEC setiap mesin terhadap nilai referensi. Obyek penelitian menggunakan lima buah mesin bubut uji berkapasitas daya medium. Hasil kajian menunjukkan bahwa pada kondisi ketidakselarasan sistem transmisi pulley-belt menyebabkan terjadinya inefisiensi energi mesin bubut sebesar 5%.Kata kunci: Data Envelopment Analysis ,efisiensi energi, ketidakselarasan, SEC ABSTRACTThe pulley belt transmission system's misalignment condition on turning machine affects the low-efficiency value of machine tool energy consumption. This study aims to evaluate the energy efficiency of a lathe in the alignment and misalignment of the pulley-belt transmission system. This study used a method of assessing the specific energy consumption (SEC) of the lathe machining process. During the cutting process, the total energy consumption value is measured using a power analyzer and processed into SEC data values, then analyzed using Data Envelopment Analysis to obtain a reference value. The assessment is obtained by comparing the distance between each machine's SEC value and the reference value. The case study's object was conducted on five test lathes with medium power capacity. The study results show that the pulleybelt transmission system's misalignment causes the lathe's energy inefficiency of more than 5%.Keywords: Data Envelopment Analysis, efficiency energy, misalignment, SEC

Abstract

The technology  of adding manufacturing or 3D printing is one of the main issues in the concept of technology 4.0. The construction design of the 3D printing machine and the deflection of its construction significantly affect the accuracy of the dimension and shape the printed product. The study aims to obtain a construction design of a cartesian type 3 D printing machine based on fused deformation modelling, and to verify the maximum value of the deflection of the machine axis. The study method used VDI222, calculation analysis, and Finite Element Analysis (FEA) simulation using CAE Solidworks software to verify the strength and deflection of the machine design construction. The study results show the construction design of 3D printing machine has been obtained according to the requirement. The verified maximum deflection value is 0.036 mm, hence the maximum error in the dimensions and shape of the printed product for each layer will still be within the standard tolerance. In addition, its maximum deflection value is verified within the radial clearance value of each determined machine axis bearing.

Abstract

Preventive maintenance (PM) implementation at POLMAN Bandung is scheduled to follow the lecture schedule so that the implementation of activities does not interfere with the lecture process. Even though the scheduling of preventive maintenance activities at POLMAN Bandung has been made quite well, there are problems in its implementation, including some activities that were not detected in the previous PM implementation, both in the form of activity reports and machine history updates. This can confuse subsequent pm implementers, as it can result in mishandling. As for the cause of the problem, there are two possibilities, namely the implementation of preventive maintenance is not carried out or the implementation of preventive maintenance has been carried out, but reports on the implementation of activities are not prepared and stored by procedures (human error). To overcome this, the researchers developed an Android-based application that functions as a reminder, recorder, and controller, for the pm process, named Reminder & Control System Management (RCSM). RCSM will remind, the implementers, to be on schedule, carry out a remind mechanisms, and information broadcast and validation until the completion of preventive maintenance activities is acceptable to the relevant authorities. Likewise, for reporting and recording engine history a system will be created with a similar mechanism. The results that have been achieved are the application software prototype reaching 100% and several field trials have been carried out. This application can direct pm implementers to avoid misuse of pm implementation procedures so that preventive maintenance implementation data can be recapitulated.
