Abstract

To determine the cause of frequent occurrence of defects required data processing using seven basic tools such as p control chart because the data is attribute data, pareto diagram to see part of the most dominant defect and cause-effect diagram to analyze the causes of disability. From the data processing done for the p control chart produced some printer models appear to be in a state of statistical control. And there are some models that are not in the condition of statistical control as evidenced by the release of some data in the chart control chart p. Pareto diagram can be known from experience that the greatest disability of all models are board games and housing assy lower. While the cause-effect diagrams that most contribute to the causes defect fail part is the part or parts of disability by itself. By looking at the data processing and analysis can be known that the defect that often happens is bad or defective component functions. And to improve the quality of SIDM assembly process in PT. Indonesia EPSON Industry needs to be improved by applying methods of SQC (Statistical Quality Control).

Abstract

The development of the manufacturing industry in a country indicates the development of the national industry. The development can be evaluated by both product quality and performance of the industry as a whole. In enhancing the competitiveness of local products, the government attempted to improve the industrys ability to produce a quality product or component. This research was conducted to determine how domestic manufacturing companies have increased their use of domestic components in producing their products. Results of the determination of the value of the domestic component level (DCL) showed that the company manufacturing clutch uses a lot of local components in the country. This is possible because when setting the value of DCL, the human resources involved in the production provided very much contribution.

Abstract

Production machines can be a barrier for the on time product availability. If there is no time consideration of the usage of production machines or less in maintenance, the machines will not be used in product processing. In the case of tool punch Heading machine in which the machine need to maintain in the right period of time using Age Replacement method. This method can help management to determine the period in inspection and preventive maintenance. Based on time period, preventive maintenance that was done can be decrease downtime, increase machines availability and reliability.

Abstract

Parameterization of surface momentum flux estimates near-surface turbulent momentum fluxes from differences of mean wind speeds between the surface skin and the mid-mixed layer (ML). The rate of this turbulent transport is proportional to the product of a convective velocity times an empirical transport coefficient. To further investigate parameterization of surface momentum flux, some topics are discussed. New data from three different sites within Boundary Layer Experiment - 1996 (BLX96) are presented, and used to evaluate surface momentum flux parameterization. Old data from three other field programs (BLX83, Koorin, and TOGA-COARE) are re-analyzed to test this parameterization. Evidence from virtually all of these experiments indicates that the empirical transport coefficients for momentum fluxes depend on surface roughness.Fluks momentum turbulen dekat permukaan dapat diestimasi dari selisih antara kecepatan angin di batas permukaan (surface skin) dan di bagian tengah lapisan tercampur (mid-mixed layer). Kecepatan dari transpor turbulen ini sebanding dengan perkalian antara koefisien empiris transpor dengan kecepatan konvektif. Untuk pengamatan lebih lanjut akan didiskusikan beberapa hal. Data baru dari hasil pengukuran BLX96 pada 3 lokasi yang berbeda akan digunakan untuk mengevaluasi parameterisasi ini. Sementara data yang diperoleh dari yang pernah dilakukan sebelumnya (BLX83, Koorin, and TOGA-COARE) digunakan untuk menguji hasil parameterisasi ini. Hasil yang diperoleh mengindikasikan bahwa koefisien empiris transpor untuk fluks momentum tergantung pada kekasaran permukaan (surface roughness).

Abstract

A new improved flux – profile relationship for winds in convective conditions isconstructed from convective transport theory and radix layer theory. Data from theMinnesota field experiment are used to recalibrate the new parameterization andsimilarity equation, and data from BLX96 are used to determine whether radix layerwind profile depends on surface conditions such as roughness. The results arecompared against independent data collected during the Koorin field campaign. Theflux-profile relationship for wind speed is dependent on a wide-range of scales ofterrain roughness. First the ML transport coefficient for momentum flux C* D dependson small-scale roughness elements as affect the aerodynamic roughness length zo .Second, shape parameter D M depends on resolvable-scale topographic variations asaffect the standard deviation of terrain elevation σz . Such dependence over the widerange of scales should be expected because the radix layer profile equations weredesigned and calibrated as the average over a heterogeneous region, rather thanbeing for one column over a single land use.Sebuah persamaan baru keterkaitan antara fluks dan profil untuk angin pada kondisikonvektif dibangun dari teori transpor konvektif dan teori lapisan radix. Data darieksperimen lapangan di Minnesota digunakan untuk kalibrasi ulang. Data eksperimenlapangan BLX96 digunakan untuk menguji kebergantungan profil angin pada kondisipermukaan. Data ekperimen lapangan di Koorin digunakan untuk pembanding.Persamaan keterkaitan antara fluks dan profil untuk angin bergantung pada berbagaiskala kekasaran permukaan. Pertama, koefisien transpor untuk fluks momentumbergantung pada elemen kekasaran permukaan skala kecil. Kedua, parameter bentukprofil bergantung pada variasi berskala topografi. Kebergantung pada berbagai skalaseperti ini adalah konsekuensi logis dari persamaan profil di lapisan radix yangdidesain dan dikalibrasi menggunakan eksperimental data yang mengakomodasipengaruh berbagai skala.

Abstract

Parameterization of surface heat flux estimates near-surface turbulent heat fluxes fromdifferences of potential temperature between the surface skin and the mid-mixed layer(ML). The rate of this turbulent transport is proportional to the product of a convectivevelocity times an empirical transport coefficient. New data from three different siteswithin Boundary Layer Experiment - 1996 (BLX96) are used to evaluate surface heatflux parameterization. Old data from six other field programs (BLX83, Koorin, FIFE,Monsoon 90, HAPEX-MOBILHY, and TOGA-COARE) are re-analyzed to test thisparameterization. Evidence from virtually all of these experiments indicates that theempirical transport coefficient for heat fluxes ( C* H ) does not depend on surfaceroughness. Positive turbulent heat fluxes are observed to exist near the bottom of theML even when there is zero potential temperature difference ( ∆θ =0) between thesurface skin and the mid-ML. Evidence suggests that positive heat fluxes could alsooccur when the surface skin has a slightly colder potential temperature than the mid-ML, implying a flux that is opposite or counter to the potential-temperature difference.Such counter-difference fluxes could be explained by an infrared radiative transferfrom the surface skin, or by non-equilibrium conditions during rapidly-changinginsolation near sunset.Fluks panas turbulen dekat permukaan dapat diestimasi dari selisih antara suhupotensial di batas permukaan (surface skin) dan di bagian tengah lapisan tercampur(mid-mixed layer). Kecepatan dari transpor turbulen ini sebanding dengan perkalianantara koefisien empiris transpor dengan kecepatan konvektif. Data baru dari hasilpengukuran BLX96 pada 3 lokasi yang berbeda akan digunakan untuk mengevaluasiparameterisasi ini. Sementara data yang diperoleh dari yang pernah dilakukansebelumnya (BLX83, Koorin, FIFE, Monsoon 90, HAPEX-MOBILHY, and TOGA-COARE) digunakan untuk menguji hasil parameterisasi ini. Hasil yang diperolehmengindikasikan bahwa koefisien empiris transpor untuk fluks panas tidak tergantungpada kekasaran permukaan (surface roughness). Bukti juga menunjukkan bahwafluks panas positif dapat terjadi ketika suhu potensial di surface skin sama atau sedikitlebih dingin daripada di mid-mixed layer. Kejadian seperti ini, disebut counter-difference fluxes, dapat dijelaskan dengan tranfer radiasi infra merah dari surface skinatau dengan kondisi ketidaksetimbangan perubahan secara cepat insolasi saatmendekati matahari terbenam.

Abstract

Pesan kebencian (hate speech) mengiringi kebebasan berpendapat di media baru (New Media). Dalam konteks Indonesia, fenomena ini menguat terutama saat berlangsungnya hajatan politik seperti pemilihan legislatif (pileg), pemilihan presiden (pilpres), atau pemilihan kepala daerah (pilkada). Sejak pilpres 2014 lalu, istilah ‘hater’ pun dikenal luas, yang menandai orang-orang dengan kecenderungan membuat pesan-pesan bernada kebencian pada orang atau kelompok tertentu. Khususnya bagi netizen (pengguna internet) kalangan muda—yakni generasi Y dan Z, praktik komunikasi dengan pesan-pesan kebencian ini harus mendapat perhatian khusus. Selain karena pewaris bangsa ini, generasi tersebut lah yang kini mewarnai dunia maya. Merekalah warga asli dunia digital (digital native). Mereka sadar akan hak untuk berbicara dan berekspresi, tapi seringkali lupa bahwa ranah online adalah ranah publik yang melekat di dalamnya tanggung jawab normatif. Tulisan ini mengkaji upaya menghadapi pesan kebencian melalui perspektif teori literasi media. Diasumsikan, melalui peningkatan literasi media, netizen akan lebih memiliki konstruksi yang positif dalam memanfaatkan media online. Literasi media yang tinggi, akan ditandai oleh: (1) daya kritis dalam menerima dan memaknai pesan, (2) kemampuan untuk mencari dan memverifikasi pesan, (3) kemampuan untuk menganalisis pesan dalam sebuah diskursus, (4) memahami logika penciptaan realitas oleh media, dan (5) kemampuan untuk mengkonstruksi pesan positif dan mendistribusikannya kepada pihak lain. Kata Kunci: Pesan Kebencian, Media Online, Literasi Media
