This research aims to find out the growth of I. cylindricaweed after cutting at various density conditions so that it can be determined the interval of precise control mechanically in the pipeline PetroChina International Jabung Ltd. The research was conducted by making random sample plots in various conditions of I. cylindrica population density. There were three population densities of I. cylindricaobserved, namely dense,mediun and rare. The results showed that height, number of tillers and dry weight of I. cylindrica were higher in dense and medium population densities than rare population densities. There is a shift in the dominant weed species in each condition of population density after cutting. The community of vegetation before and after cuttingat dense population density was classified as homogeneous with C value of 78.05%, while at medium and rare population density it wasclassifiedas heterogeneous with C value of < 75%.Keywords:Imperata cylindrica, growth of weed, population density, species shift
Intellectual capital berarti jumlah dari yang dihasilkan oleh tiga elemen utama organisasi (human capital, structural capital, customer capital) yang berkaitan dengan pengetahuan dan teknologi yang dapat memberikan nilai bagi perusahaan guna menciptakan keunggulan kompetitif dalam bersaing. Penelitian ini bertujuan untuk membuktikan adanya pengaruh intellectual capital terhadap economic value added pada perusahaan. Penelitian ini juga menggunakan variabel kontrol size dan leverage yang menggambarkan aktivitas perusahaan dalam meningkatkan EVA. Sampel observasi yang digunakan berupa data laporan keuangan dari perusahaan yang terdaftar di Bursa Efek Indonesia (BEI) selama periode 2018-2020. Metode analisis data adalah analisis regresi berganda dengan pengolahan data yang dilakukan menggunakan aplikasi SPSS. Penelitian ini juga menggunakan uji robusness test untuk mengukur ketahanan data dari hasil penelitian. Hasil penelitian dapat disimpulkan bahwa intellectual capital dan leverage yang diproksikan dengan DAR tidak berpengaruh signifikan terhadap economic value added. Sedangkan size berpengaruh signifikan terhadap peningkatan economic value added.
