Analisis Kebutuhan Man Power Dan Line Balancing Jalur Supply Body 3 D01N PT. Astra Daihatsu Motor Karawang Assembly Plant (KAP)

Dalam proses produksi terutama Perusahaan yang baru membuka cabang PT. ADM Karawang Assembly Plant (KAP) yaitu Departemen Body (Welding) pada tack time 5,3 menit terjadi masalah yaitu banyaknya waktu menganggur masing-masing team member yaitu sebesar 381 menit, dan balance delay sebesar 27,13%. Dan dengan adanya planning capacity up yang apabila dengan kondisi man power yang sama maka akan terjadi beban kerja yang berlebihan yaitu sebesar 29% dan banyaknya waktu over time yaitu yang bisa mencapai 242 menit. Maka dari itu peneliti berupaya untuk mencari tahu penyebab dari permasalahan tersebut. Dalam pengiriman part ke jalur, pos supply merupakan bagian dari departement body yang sangat berpengaruh terhadap potensi timbulnya masalah tersebut.Adapun metode yang digunakan untuk menyelesaikan masalah tersebut digunakan metode Rank Position Weight, Region Approach dan Largest Candidate Rule karena metode tersebut dianggap paling sesuai untuk membandingkan kondisi awal dengan kondisi setelah perencanaan metode line balancing pos Supply Body 3 ADM KAPDari analisis dari ketiga metode didapatkan hasil perhitungan balance delay awal 26.66% berkurang menjadi 1.59% dengan metode Ranked Position Weight, 3.84% dengan metode Largest Candidate Rule dan 4.94% dengan metode Region Approach. Efisiensi lintasan dari kondisi awal sebesar 73.34 % meningkat menjadi 98.41% dengan metode Ranked Position Weight, 96.16% dengan metode Largest Candidate Rule dan 95.06% dengan metode Region Approach. Sehingga perencanaan line balancing dengan metode Rank Positional Weight dapat digunakan dalam pemecahan masalah pada pos supply Body 3 PT.ADM KAP

Electrical power generating system

A power generating system for adjusting coupling an induction motor, as a generator, to an A.C. power line wherein the motor and power line are connected through a triac is described. The triac is regulated to normally turn on at a relatively late point in each half cycle of its operation, whereby at less than operating speed, and thus when the induction motor functions as a motor rather than as a generator, power consumption from the line is substantially reduced

Development of an AC-DC buck power factor correction

Generally all devise used in industrial, commercial and residential applications need to undergo rectification for their proper functioning and operation. It connected to the non-linear loads which results in production of non-sinusoidal line current. Due to the increasing demand of these devices, the line current non-sinusoidal pose a major problem by degrading the power factor of the system thus affecting the performance of the devices. Hence there is a need to reduce the line current non-sinusoidal so as to improve the power factor of the system and led to designing of Power Factor Correction circuits. Power Factor Correction (PFC) involves two techniques, Active PFC and Passive PFC. In our project work we have designed an active power factor circuit using Buck Converter for improving the power factor. The advantage of using Buck Converter in power factor correction circuits is that better line regulation is obtained with appreciable power factor. Simulation and experimental are conducted to validate the theoretical analysis. The results show that the power factor can be improved

Zero forcing in iterated line digraphs

Zero forcing is a propagation process on a graph, or digraph, defined in linear algebra to provide a bound for the minimum rank problem. Independently, zero forcing was introduced in physics, computer science and network science, areas where line digraphs are frequently used as models. Zero forcing is also related to power domination, a propagation process that models the monitoring of electrical power networks. In this paper we study zero forcing in iterated line digraphs and provide a relationship between zero forcing and power domination in line digraphs. In particular, for regular iterated line digraphs we determine the minimum rank/maximum nullity, zero forcing number and power domination number, and provide constructions to attain them. We conclude that regular iterated line digraphs present optimal minimum rank/maximum nullity, zero forcing number and power domination number, and apply our results to determine those parameters on some families of digraphs often used in applications

Coupling an induction motor type generator to ac power lines

A system for coupling an induction motor type generator to an A.C. power line includes an electronic switch means that is controlled by a control system and is regulated to turn on at a relatively late point in each half cycle of its operation. The energizing power supplied by the line to the induction motor type generator is decreased and the net power delivered to the line is increased

Enhancing Power Line Communication Utilization by an Enhanced Hybrid Bandwidth Allocation Scheme

[[abstract]]Thanks to the rapid development of the Internet in the past ten years, all kinds of wideband services have been proposed and adopted successively and power line network, which offers an environment of low cost deployment, is no exception. Because power lines have existed in every corner of the world, its deployment cost is comparatively low compared with other types of networks. Generally speaking, power line communication (PLC) and wireless network use the same transmission medium and their channels must be allocated for users to use simultaneously. However, there are still some differences between them. For example, compared with wireless network, the migration rate of power line communication users is more stable. Due to the physical characteristics of the transmission medium, users not only use the same transmission medium, but also share the contents of the medium. In this paper, by extending the concept of hybrid algorithms to power line communication, we modify and adjust the scheme based on the features of power line communication. With the simple synchronization, every node can calculate the optimal bandwidth proportion for transmission on its own and the functions of power line network thus can be further optimized.[[notice]]補正完畢[[booktype]]電子版[[booktype]]紙
