Abstract

Mita Sani Jaya merupakan salah satu agen yang bergerak dibidang distribusi gas LPG 3 kg kepada pangkalan. Proses pengiriman gas LPG 3 kg dilakukan dari hari Senin hingga Sabtu ke 55 pangkalan, berdasarkan studi pendahuluan terhadap proses pengiriman gas LPG 3 kg ditemukan permasalahan yaitu waktu tempuh pengiriman cukup panjang serta sarana pengangkut dan kapasitas yang terbatas. Selama ini agen belum merancang rute dan jadwal pengiriman gas LPG 3 kg dari pangkalan satu ke pangkalan lainnya dengan pemlihan rute dan penjadwalan yang konsisten dan optimal. Penelitian ini bertujuan untuk menentukan rute dan penjadwalan pengiriman gas LPG 3 kg di PT. Mita Sani Jaya sehingga waktu tempuh yang optimal, algoritma Clarke and Wright Savings digunakan untuk meminimumkan waktu tempuh dengan mempetimbangkan kapasitas kendaraan. Berdasarkan hasil perhitungan penjadwalan dengan menggunakan software LINDO 6.1, Maka diperoleh penghematan waktu tempuh pengiriman tabung gas LPG 3 kg PT.Mita Sani Jaya pada hari pertama sebesar 64 menit, hari kedua 111 menit, hari ketiga 92 menit hari ke empat 80 menit, hari ke lima 57 menit dan hari ke enam sebesar 54 menit. Hal ini menunjukan bahwa algoritma Clarke and Wright Savings dengan bantuan software LINDO 6.1 dapat mengurangi waktu tempuh pengiriman. Kata kunci : pendistribusian gas LPG 3 kg, waktu tempuh, penentuan rute dan penjadwalan.

Abstract

This study aims to develop a BLDC design which is the main component in the conversion of a hybrid scooter motorcycle. The 1KW BLDC motor is designed as a plug-in powertrain embedded in the rear wheel of the scooter which aims to convert the powertrain from the Internal Combustion Chamber (ICE) to a Hybrid ICE-Electric. The BLDC motor is designed based on the results of field observations to be embedded in a scooter motor with a capacity of 110-150cc, with the appropriate BLDC motor specifications being 1000W power, 48VDC working voltage with a maximum rotational speed of 500Rpm. The next stage in the BLDC design is to determine the number of magnetic poles (poles) for the rotor, calculate the number of coils for the stator and cable specifications related to the required electric current. The results obtained from this study are the BLDC design for the conversion of a hybrid scooter with specifications of 1000W 48VDC 520Rpm, 11 pole-pairs rotor with a magnetic flux of 0.00024 weber, 18 stator coils with 589 turns of 1mm copper wire, and a strong current of 14.49A. Based on theoretical calculations, the BLDC motor will be able to produce a torque of 13.52 Nm.

Abstract

Sling bearings are one of the important components in the cable car transportation system. These bearings function to support the weight of the cable car and reduce friction between the train and the rail/sling so that the train can move smoothly and safely. To produce quality sling bearings, a precise and accurate machining process is required. The manufacturing process of ropeway sling bearings goes through a machining process, where raw materials that are usually metals or metal alloys will be cut, shaped, and polished to form the desired bearing shape. Fixture machining is one of the most commonly used techniques in the machining process, where the workpiece is clamped or fastened to a specially designed fixture so that the workpiece remains stable during the machining process. The purpose of this engineering is to produce a fixture design for sling bearing components with increased quantity and quality of products on CNC machines by validating the design through simulation. In this study, tests were conducted using a conventional machining fixture and a machining fixture equipped with a pneumatic system. The test results show that the machining fixture equipped with a pneumatic system is able to increase the production speed and efficiency of cable car sling bearings by up to 20% compared to the conventional fixture. This research makes an important contribution to the cable car sling bearing manufacturing industry in improving production efficiency and final product quality. In addition, this research can also be a reference for further research on the optimization of the cable car sling bearing production process.

Abstract

PT.XYZ mengalami ketidak balancenya loding vs capacity pada produksi line assy caliper 2 dengan selisi produksi 13 pcs/jam selisi cycle time current terhadap take time adalah sebesar 2.1 detik data ini sesuai dengan laporan produksi line assy caliper 2 , Gap ini terjadi akibat proses clamping griper mesih dilakukan secara manual akibatnya banyak waktu Muda ( sia-sia ) pada proses tersebut. Sering terjadi part terjatuh , part susah dipasang dan dilepaskan sehingga berakibat proses jadi delay selama 2,1 detik laporan ini terlihat pada grafik monitoring problem line produksi assy caliper 2 . Dengan konsep melakukan penelitian dilapangan produksi langsung kemudian menganalisa kareteristik proses produksi diharapkan problem yang terjadi dapat dicarikan solusi untuk menghilangkan waktu MUDA ( Sia-sia ). Dari hasil penelitian ini membuktikan bahwa memodifikasi jig & fixture dengan pendekatan prinsip 6 Degree Of Freedom dapat menghilangkan gap produksi pada line assy calip er 2 sebesar 2,1 dtk atau 13 pcs /jam dengan cara merubah proses produksi manual menjadi Otomasi dan membuat jig & fixture pencekam benda kerja yang peneliti sebut Chuki-chuki Otomation. Hasilnya setelah dirubah system manual ke otomasi dengan menggunakan Chuki-Chuki pencekam proses loading dan unloading caliper di line assy caliper dapat dihilangkan sehinga bisa mengurangi waktu 1,5 dtk waktu loading dan unloading

Abstract

PT. XYZ is a company engaged in the plastic packaging (Flexible Packaging) industry in Indonesia and has customers from national to international levels. The large demand for plastic packaging requires companies to be able to meet every customer request. This large number of requests has an impact on the many types of products that must be fulfilled by the company, resulting in increased downtime during the change order process, especially on printing machines. With the lean manufacturing approach, there is a 5S method (seiri, seiton, seiso, seiketsu and shitsuke) as a way of creating and maintaining a quality work environment. After making observations, it is known that there are several activities that can be categorized as waste in the product replacement process, including waiting time, defects, excessive transportation and unnecessary motion. After processing with the 5S method, an improvement plan is made. At the Seiri stage, the improvements that must be made are by giving Red Tags, for the Seiton stage, the improvements are moving the preparation area and placing ink cans. At the Seiso stage, the improvements needed to make checksheets and layouts were made, at the Seiketsu stage, improvements were made to work instructions and making 5S posters, and finally, at the Shitsuke stage, training and outreach were carried out as well as periodic evaluations.

Abstract

In industrial processes, measurement is an important variable. In industrial processes a lot must be controlled. Among them are pressure (pressure) in a pipe, flow in a pipe, temperature, and surface liquid (level) in a tank. Transmitter is used as a physical signal converter into a signal or sends signals from the transmitter device (sensor) to the controller and from the controller to the final controller. In this case, level measurement will be discussed by calculating the transmitter value to get accurate results before being installed in the field.
