"Hasil produksi yang tidak stabil, yang diakibatkan oleh tingkat cacat produk yang tinggi dan penerapan push system menghasilkan pemborosan-pemborosan seperti, banyaknya jumlah inventori dan jumlah produk cacat, penanganan material yang berlebihan, dan gerakan-gerakan kerja yang tidak perlu. Dalam penelitian ini Value Stream Mapping digunakan untuk memetakan kondisi proses yang aktual, dengan tujuan untuk menemukan pemborosan-pemborosan yang ada. Dari peta lama disusunlah peta baru yang dirancang untuk meminimalkan proses-proses yang tidak menambah nilai pada produk yang dibuat Perilaku dari peta yang baru kemudian diperiksa dengan menggunakan simulasi. Pembuatan Detail Process Chart dari proses yang sekarang berjalan digunakan untuk memahami pemborosan dalam proses penanganan produk cacat yang tinggi.
Solusi dari masalah ini dirancang dalam proposed detail process chart sebagai panduan operasi yang baru. Kelebihan dari process chart ini adalah kemampuan dalam menggambarkan langkah proses dengan sangat detail, yang memudahkan untuk menganalisa dan membuat perbaikan terhadap proses yang sedang berjalan. Dari future map yang telah disimulasikan, didapatkan pengurangan production lead time sebesar 60,58%, dan pengurangan waktu pengerjaan 1000 unit produk, sebesar 29,88%.
Production output variation, that caused by high defect rate and push production system, produces wastes like, high inventory, defect product, poor material handling, and unnecessary motion. In this study Value Stream Mapping used for mapping current process, to find wastes. Future map is build based on current condition, which is designed for minimizes process that not add value to the product, after that the behavior of proposed production system is checked by using simulation. Detail process chart is used for understanding the wastes that related to high defect rate. The solution for this problem is constructed in proposed detail process chart as a new guidance for the operation. This process chart is able to visualize in detail, steps in a process that it will make easier to analyze and propose improvement in current condition. From the simulated future state, we got 60,58% reduction in production lead time, and 29,88% reduction in process time to produce 1000 unit product."

"Penelitian ini mengkaji aspek ergonomis pada desain kabin kokpit pesawat perintis berpenumpang 19 bermesin dua dalam model Virtual Environment. Tujuannya adalah untuk menghasilkan usulan rekomendasi desain kabin kokpit pada pesawat perintis yang ergonomis, sesuai dengan hasil uji nilai PEI. Dihasilkan 9 bbuah konfigurasi yang akan dianalisis. Analisa postur menggunakan software Jack 6.1. Pendekatan metode yang digunakan adalah metode Posture Evaluation Index (PEI) yang mengintegrasikan analisis dari tiga metode analisis yang terdapat pada Task Analysis Toolkits yang ada pada software Jack 6.1, yaitu : Low Back Analysis, Ovako Working Posture Analysis System, dan Rapid Upper Limb Assessment. Hasil penelitian ini yaitu usulan konfigurasi desain dengan jarak tuas kemudi 25 cm dari instrument panel dan titik koordinat lever thrust pada x = 22 cm dan z = 426 cm pada center console.
This research studies the ergonomics aspect from cockpit design of Double Engined 19-Passenger STOL (Short Takeoff and Landing) Utility Aircraft in Virtual Environment. The purpose of this research was to make ergonomic designs recommendation for flight deck of 19-passenger STOL Utility Aircraft according to the PEI test result. Jack 6.1 was used to analyze the posture. Posture Evaluation Index (PEI) was an approach that integrated the results of these three analysis methods which were contained in Task Analysis Toolkits. Those three methods are: Low Back Analysis, Ovako Working Posture Analysis System, and Rapid Upper Limb Assessment. The result was the configuration with range of yoke at 25 cm from panel instrument, 11o angle of the torso for the pilot, and change of coordinat point from thrust lever in center console at x = 22 cm and z = 426 cm."

"Performans produksi babi dipengaruhi oleh konsumsi pakan. Eksetra puyuh memiliki kualitas tinggi dengan kadar protein kasar dan energi masing-masing 31,03% dan 3139,44 kal/gram sebagai bahan pakan pengganti dalam ransum ternak babi. penelitian bertujuan untuk mengetahui performans produksi babi keturunan Landrace yang mengkonsmsi pakan subtitusi tepung ikan dengan ekskreta puyuh. Penelitian ini menggunakan 12 ekor ternak babi jantan kastrasi keturunan landrace berumur 2,5 bulan dibagi menjadi 4 perlakuan: (PO) Broiler II, bekatul, tepung ikan; (P1) substitusi 10% tepung ikan dengan tepung ekskreta puyuh; (P2) subtitusi 20% tepung ikan dengan tepung ekskreta puyuh ; (P3) substitusi 30% tepung ikan dengan tepung ekskreta puyuh. Masing-masing perlakuan terdiri dari 3 ekor ternak babi. Variabel yang diamati meliputi pertambahan berat badan, konsumsi pakan, dan konversi pakan. Data dianalisis dengan analisis variansi dengan rancangan acak kelompok pola searah dan menggunakan uji lanjur Duncan's Multiple Range Test. Hasil penelitian menunjukkan bahwa pertambahan berat badan, konsumsi pakan; dan konversi pakan tidak berpengaruh nyata (P > 0,05). Penggunaan substitusi tepung ikan dengan ekstra puyuh dalam pakan dianjurkan digunakan sebanyak 20%, karena substitusi eksreta puyuh sebanyak 30% menyebabkan penurunan pertumbuhan. "

"Industrial process identification and control design is devoted to advanced identification and control methods for the operation of continuous-time processes both with and without time delay, in industrial and chemical engineering practice. The simple and practical step- or relay-feedback test is employed when applying the proposed identification techniques, which are classified in terms of common industrial process type : open-loop stable, integrating; and unstable, respectively. Correspondingly, control system design and tuning models that follow are presented for single-input-single-output processes. Furthermore, new two-degree-of-freedom control strategies and cascade control system design methods are explored with reference to independently-improving, set-point tracking and load disturbance rejection. Decoupling, multi-loop, and decentralized control techniques for the operation of multiple-input-multiple-output processes are also detailed. Perfect tracking of a desire output trajectory is realized using iterative learning control in uncertain industrial batch processes. All the proposed methods are presented in an easy-to-follow style, illustrated by examples and practical applications. "

"The book covers comprehensively a range of power-system control problems: from steady-state voltage and power flow control, to voltage and reactive power control, to voltage stability control, to small signal stability control using FACTS controllers.
In the six years since the first edition of the book has been published research on the FACTS has continued to flourish while renewable energy has developed into a mature and booming global green business. The second edition reflects the new developments in converter configuration, smart grid technologies, super power grid developments worldwide, new approaches for FACTS control design, new controllers for distribution system control, and power electronic controllers in wind generation operation and control. The latest trends of VSC-HVDC with multilevel architecture have been included and four completely new chapters have been added devoted to Multi-Agent Systems for Coordinated Control of FACTS-devices, Power System Stability Control using FACTS with Multiple Operating Points, Control of a Looping Device in a Distribution System, and Power Electronic Control for Wind Generation."

"The tools and techniques used in Design of Experiments (DoE) have been proven successful in meeting the challenge of continuous improvement in many manufacturing organisations over the last two decades. However research has shown that application of this powerful technique in many companies is limited due to a lack of statistical knowledge required for its effective implementation.
Although many books have been written on this subject, they are mainly by statisticians, for statisticians and not appropriate for engineers. Design of Experiments for Engineers and Scientists overcomes the problem of statistics by taking a unique approach using graphical tools. The same outcomes and conclusions are reached as through using statistical methods and readers will find the concepts in this book both familiar and easy to understand.
This new edition includes a chapter on the role of DoE within Six Sigma methodology and also shows through the use of simple case studies its importance in the service industry. It is essential reading for engineers and scientists from all disciplines tackling all kinds of manufacturing, product and process quality problems and will be an ideal resource for students of this topic."
