PERANCANGAN ALAT UKUR KEMIRINGAN BIDANG MENGGUNAKAN MIKROKONTROLER AT89C51
Get PDFPenelitian ini bertujuan untuk merancang prototipe alat ukur kemiringan bidang datar. Alat ini nantinya dapat difungsikan untuk melihat kemiringan lantai, dinding ataupun melihat suatu kemirigan bidang lainnya. Prinsip kerja dari alat ini adalah mengambil data untuk diolah dan ditampilkan diperoleh dari pergerakan bandul pendulum gravitasi. Potensiometer sebagai sensor sudut bergerak karena pengaruh gaya gravitasi dan selalu tegak lurus dengan bidang datar yang diukur (pada posisi horizontal x-y), disaat itu pula potensiometer yang bergerak mengakibatkan perubahan nilai resistansinya. Pada posisi bandul pendulum diam berhenti mencapai keseimbangannya maka perubahan nilai tahanan potensiometer akan diukur keluaran nilai tegangannya dengan menggunakan prinsif pembagi tegangan (voltage devider) sebagai masukan rangkaian pengkondisi sinyal yang akan menghasikan nilai tegangan analog tetentu. Kemundian tegangan analog tersebut oleh ADC (Analog to Digital Converter) diubah menjadi pulsa digital yang diumpankan ke mikrokontroler. Mikrikontroler membaca tegangan ADC dan akan mencari data sudut pada table dan apabila menemukan data yang sesuai akan ditampilakan oleh LCD (Liquit Crytal Display). Perancangan prototipe alat ini mempunyai beberapa spesifikasi diantaranya adalah dengan menggunanakn sensor potensiometer, batas ukurnya antara 0˚ sampai 90˚ dengan resolusi terkecil penguuran sebesar 1˚ dan menggunakan power supply berupa bateri 9 volt
Manajemen Risiko Di PT. Industri Kereta Api (Persero) Untuk Menghadapi Ketidakpastian Supply Chain
Get PDFPerhatian mengenai risiko dan bagaimana cara menangani resiko secara berlanjut telah mengalami pengembangan dalam satu dekade terakhir. Industri barang dan jasa seperti industri kereta api PT. INKA sering dihadapkan pada berbagai risiko yang bisa menyebabkan gagalnya sebuah tujuan yang hendak dicapai. Risiko itu terdiri dari faktor resiko eksternal seperti bencana alam dan risiko internal seperti jeleknya sistem supply chain management pada lembaga itu, ketidakpercayaan, serta masalah komunikasi antar personil. Untuk mengantisipasi dan mengatasi masalah-masalah risiko supply chain secara efektif hendaknya dikembangkan suatu konsep Supply Chain Risk Management (SCRM). Dalam penelitian ini akan dilakukan kajian risiko supply chain pada Divisi Manufaktur PT. INKA mulai dari sistem perencanaan, pengadaan, produksi, sampai distribusi produk yang merupakan usaha untuk mengetahui, menganalisis dan mengendalikan risiko dalam setiap kegiatan untuk memperoleh efektifitas dan efisiensi. Pendekatan yang digunakan dalam penelitian ini adalah Manajemen Risiko yang bersumber dari Standards Australia/Standards New Zealand 1999 dengan elemen pokok : menetapkan ruang lingkup (konteks), pengidentifikasian risiko, melakukan analisis dan evaluasi terhadap risiko untuk mendapatkan level risiko dengan menggunakan pengembangan metode Failure Modes and Effects Analysis (FMEA) dan pengembangan metode Quality Function Deployment (QFD). Dari level risiko yang didapatkan, kemudian direncanakan langkah-langkah yang tepat untuk mereduksi sebab dan akibat kemungkinan terjadinya risiko pada bagian supply chain dimasa mendatang. Hasil yang diperoleh menunjukkan bahwa terdapat 30 kejadian risiko dan 28 agen risiko. Berdasarkan nilai korelasi perhitungan House of Risk (HOR) terdapat 7 agen risiko final yang perlu ditindaklanjuti oleh manajemen. Dari analisa dan interpretasi data ternyata strategi supply merupakan pilihan strategi yang bisa memberikan benefit optimal karena kompleksitas dari supply chain perusahaan
====================================================================================================================================
Attention to risk and how to handle risk continuously has been developing in the last decade. Goods and services industries such as the railway industry of PT. INKA are often faced with various risks that can cause failure of a goal to be achieved. The risks consist of external risk factors such as natural disasters and internal risks such as poor supply chain management systems in the institution, distrust, and communication problems between personnel. To anticipate and overcome supply chain risk problems effectively, a Supply Chain Risk Management (SCRM) concept should be developed. In this study, a study of supply chain risk will be conducted in the Manufacturing Division of PT. INKA starting from the planning system, procurement, production, to product distribution which is an effort to identify, analyze and control risks in every activity to achieve effectiveness and efficiency. The approach used in this study is Risk Management which is sourced from Standards Australia/Standards New Zealand 1999 with the main elements: determining the scope (context), identifying risks, analyzing and evaluating risks to obtain risk levels using the development of the Failure Modes and Effects Analysis (FMEA) method and the development of the Quality Function Deployment (QFD) method. From the risk level obtained, then the right steps are planned to reduce the cause and effect of the possibility of risk in the supply chain section in the future. The results obtained show that there are 30 risk events and 28 risk agents. Based on the correlation value of the House of Risk (HOR) calculation, there are 7 final risk agents that need to be followed up by management. From the analysis and interpretation of the data, it turns out that the supply strategy is a strategic choice that can provide optimal benefits due to the complexity of the company's supply chai
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
