    Multivariate statistics is a branch of statistical science that discuss the analysis for multivariable case. Some analysis in multivariate statistics are discussing about inferences, there are inferences about mean vector and inferences of covariance matrices. Along with the development of technology, to support statistical analysis from both of inferences is requiring a statistical software, R is one of it with open source based. R is often used in statistical computing with command line interface (CLI) as the interface. In implementation, CLI requires the R user to remember names of used syntax and function. It makes less effective when the inferences have many related statistical analysis, so graphical user interface (GUI) needed to giving an easy way to accessing all of it. Testing for mean vectors of two populations will be performed using S. Rockiki's data about measures of oxygen consumption for 25 males and 25 females. Results about assumptions showing both populations are normal multivariate distributed and have different covariannce matrix. The conclusion from the testing for mean vectors of two populations has performed is both populations have different mean vectors. There are packages are used on construction of GUI in R, including gdata, tcltk2, and devtools with additional software like Rtools and ActivePerl. The GUI has four main menus such as File, Analysis, Plot, and Help. Based on GUI USAge, the GUI has been able to processing the chosen analysis and showing valid output.

    Hasil persilangan antartanaman berdasarkan tipe seks menghasilkan segregasi dengan proporsi yang berbeda-beda.Teknik identifikasi seks sejak fase benih sangat dibutuhkan dalam upaya mempercepat siklus generasi dan efisiensiruang uji dalam uji persilangan. Penelitian ini merupakan tahap awal untuk mengidentifikasi bibit sejak dini yaitudengan memperlakukan biji dalam larutan auksin dan ABA.Tujuan dari penelitian ini adalah untuk memperoleh datadaya pertumbuhan bibit pepaya yang diperlakukan dengan indole bu tyric acid (IBA) dan absicic acid (ABA).Penelitian ini dilaksanakan di Sumatera Barat mulai bulan Agustus 1999 sampai dengan Maret 2000. Penelitianmenggunakan Rancangan Acak Kelompok sebanyak tiga ulangan yang disusun secara faktorial. Untuk mendapatkanteknik identifikasi tersebut dapat didekati dengan mendiskripsikan benih semaian sampai dengan tanaman di polibag.Hasil penelitian menunjukkan bahwa perlakuan IBA dan ABA berpengaruh terhadap pertumbuhan daun dan tinggitanaman. IBA dan ABA tidak berpengaruh nyata terhadap di am e ter batang. Pada awal pertumbuhan, di am e ter batangdipengaruhi oleh tempat. Pengaruh IBA dan ABA nyata pada perkecambahan biji terutama untuk dampit, lokal kuningdan lokal jingga.Kata kunci : Carica pa paya; Biji pepaya; IBA; ABAAB STRACT. Triatminingsih. R., S.

    The objective of this study was to obtain a proper balance dose between biofertilizer and inorganic fertilizer in order to increase the growth and yield of rice in Inceptisol soil of lowland swamp origin. Biofertilizer was made by enriching straw compost with N2 interceptor bacteria, phosphate solvent bacteria and growth stimulator bacteria isolated from swamp lowland in South Sumatra. This study was conducted from November 2012 to March 2013 in a greenhouse. The design used was completely randomized design (CRD) factorial, with two treatment factors consisting of inorganic fertilizer (0,25, 50, 75 and 100% recommended dosage) and biofertilizer (0, 100, 200, 300, 400 and 500 kg.ha-1). The results showed that the best treatment in term of plant height at 8 weeks after planting (WAP), the maximum number of tillers, number of productive tillers, number of grains per panicle and weight of milled dry rice were obtained in combination of 75% inorganic fertilizer and 300 - 400 kg.ha-1biofertilizer

    Business analytics in industry 4.0: a systematic review

    Get PDF
    Recently, the term “Industry 4.0” has emerged to characterize several Information Technology and Communication (ICT) adoptions in production processes (e.g., Internet-of-Things, implementation of digital production support information technologies). Business Analytics is often used within the Industry 4.0, thus incorporating its data intelligence (e.g., statistical analysis, predictive modelling, optimization) expert system component. In this paper, we perform a Systematic Literature Review (SLR) on the usage of Business Analytics within the Industry 4.0 concept, covering a selection of 169 papers obtained from six major scientific publication sources from 2010 to March 2020. The selected papers were first classified in three major types, namely, Practical Application, Reviews and Framework Proposal. Then, we analysed with more detail the practical application studies which were further divided into three main categories of the Gartner analytical maturity model, Descriptive Analytics, Predictive Analytics and Prescriptive Analytics. In particular, we characterized the distinct analytics studies in terms of the industry application and data context used, impact (in terms of their Technology Readiness Level) and selected data modelling method. Our SLR analysis provides a mapping of how data-based Industry 4.0 expert systems are currently used, disclosing also research gaps and future research opportunities.The work of P.

    Kegiatan bimbingan belajar sangat berpengaruh terhadap hasil belajar bahasa Indonesia di kelas tinggi sekolah dasar. Bimbingan belajar dapat dijadikan tolok ukur keberhasilan belajar bagi para siswa sekolah dasar. Sementara itu hasil belajar bahasa Indonesia dapat dipengaruhi oleh beberapa faktor, antara lain faktor internal dan faktor eksternal siswa. Penelitian ini berfokus pada bimbingan belajar yang memengaruhi hasil belajar bahasa Indonesia siswa kelas V di SD Negeri 002 Sungai Pinang Kota Samarinda. Penelitian ini merupakan penelitian ex post facto, karena tidak ada kontrol terhadap variabel bebas dan peneliti tidak mengadakan pengaturan atau manipulasi terhadap variabel bebas. Pada penelitian ini terdiri atas dua variabel, yaitu satu variabel bebas dan satu variabel terikat. Variabel bebas dalam penelitian ini adalah bimbingan belajar (X). Sedangkan variabel terikatnya adalah hasil belajar bahasa Indonesia (Y). Berdasarkan hasil penelitian dan hasil analisis dapat diketahui dari hasil perhitungan uji hipotesis T diperoleh hasil bimbingan belajar dan hasil belajar bahasa Indonesia Thitung adalah 4,451 dengan Ttabel 1,701 sehingga dapat ditulis Thitung < Ttabel (4,451 < 1,701) yang dapat diartikan Ha diterima dan pada angket bimbingan belajar dan hasil belajar bahasa Indonesia, maka didapatkan Thitung adalah 2,541 dengan Ttabel 1,701 sehingga dapat ditulis Thitun
