Abstract

One of the molding injection Komatsu 80T in the PT Yogya Presisi Teknikatama Industry has a problem on its performance. The performance of this injecton molding can be calculated by Overall Equipment Effectiveness(OEE). OEE is a factor which can be found by multiplication of Availability Ratio, Performance Efficiency and Rate of Quality. The values of OEE then be compared to the standart values of JIPM (The Japan Institute of Plan Maintenance) which JIPM defined a minimal standard value of OEE is 85%. If the result of OEE calculation less than 85%,what causes it be analysed by the Six Big Losses Analysis. The Result of analysis showed the sequence as Reduced Speed Loss, Setup and Adjusmnet loss, and Rework Loss. Then by Fishbone diagram, it can be known the causes of the decreasing OEE values, so the management can do the repairment.

Abstract

Penelitian ini akan membahas perusahaan kimia yang memproduksi Pythalic Anhydride (PA) di Indonesia. Perusahaan ini memiliki kapasitas 70.000 Metric Ton Per Year (MTPY). Selama 2017, total waktu produksi adalah 6.699,8 jam atau rata-rata 23 hari. Namun, dibandingkan dengan kapasitas produksi, perusahaan dapat memenuhi permintaan dalam waktu 20 hari tiap bulannya. Waktu produksi minimum diperlukan untuk mencapai layanan pelanggan yang optimal dan biaya minimum. Perbedaan antara kapasitas dan kondisi yang ada disebabkan oleh penutupan pabrik. Penutupan pabrik disebabkan oleh kehabisan inventori material dan kerusakan mesin. Frekuensi penutupan pabrik relatif tinggi. Selama 2014 hingga 2017, pabrik ditutup 48 kali dengan MTTF 3,1 hari dan MTTR 23 jam. Analisis reliability, availability, dan maintainability (RAM analysis) dilakukan untuk mengatasi masalah ini. Secara khusus, penelitian ini akan fokus pada pengembangan skenario dengan melakukan percobaan pada inventori penyangga suku cadang untuk mengurangi waktu produksi dan meningkatkan availabilitas. Pendekatan simulasi digunakan dalam penelitian ini untuk memodelkan perilaku stokastik. Berdasarkan hasil percobaan, waktu produksi berkurang 232,7 jam dan availabilitas menjadi 0,8996.

Abstract

Production control systems for multistage manufacturing processes can be classified into push type (MRP) and pull type (JIT) systems. MRP and JIT system has its own unique advantages and disadvantages, and the advantages of both systems can be exploited to achieve better performance. A relatively new research trend associated with the MRP and JIT is to explore the possibility of hybrid system and to develop model for the integrated system. So, the choice of a production philosophy by a manufacturing company is important. The key components of overall profitability are holding cost inventory, WIP, set-up time and cost for missing due date on costumer order. The optimum lot-size associated with those of the key component. This paper presents an optimal lot-size production and integrated hybrid system with movable junction point between a Push sub-system and a Pull sub-system in production line using simulation approach. Using ARENA ® simulation software this model could solve the problem. The result can achieve minimum production cost with production output level for push system of 79 to 82 unit, decreasing WIP from 85.81 hour to 84.165 hour per cycle and decreasing waiting time in works station 2 to 5.Keywords : Push/Pull System, Lot-size, WIP, Manufacturing System

Abstract

This research aims to (a) investigate differences in Internet adoption; (b) identify factors affecting Internet adoption; and (c) examine differences of Internet usage pattern between male and female users. Using data from 714 respondents/students with various backgrounds, the research unveils that in general, Internet adoption among female users are lower than that among male users.  Using Technology Acceptance Model (TAM), the research also finds that the Internet adoption among female users is affected by perceived ease of use rather than perceived usefulness. On the other hand, the Internet adoption among male users is affected by perceived usefulness rather than perceived ease of use. Male users are found to have a more flexible Internet access venue when compared to female users. The research also gives an evident that Internet usage pattern among male and female users differs. Proportion of female users who use the Internet for chatting and study-related activities is significantly larger than that of male users. Conversely, proportion of male users who use the Internet for reading online news, testing and downloading software, shopping, entertainment, seeking job vacancy, and visiting pornographic sites are larger than female users. High cost Internet access and low access speed of the Internet and a lack of English proficiency are identified to be most severe obstacles of the Internet adoption in Indonesia.
