The Influence of the Audit Committee and the Remuneration Committee on Company Performance

This research aims to analyze the impact of the size of the audit committee and remuneration committee on company performance using the Kompas 100 Index for the 2013–2015 period. Company performance is measured using the proxies of return on assets (ROA) and net profit margin (NPM). The research used leverage and company size as the control variables and the purposive sampling technique as the sampling method. In addition, the model used in this research was the panel data model, with the fixed effect model being used for the ROA proxy and the random effect model being used for the NPM proxy. The results showed that audit committee size and remuneration committee size have no significant effect on ROA and NPM.   Keywords: company performance, audit committee size, remuneration committ

Pelaksanaan Layanan Penempatan Dan Penyaluran Untuk Peningkatan Potensi Non Akademik Anak Usia Dini Kelompok a Di Tk Insan Taqwa

Layanan penempatan dan penyaluran merupakan salah satu layanan Bimbingan dan konseling. Layanan penempatan dan penyaluran bertujuan untuk menempatkan peserta didik pada situasi atau keadaan dimana kelebihan, potensi atau bakat yang dimiliki dapat berkembang dengan optimal. Di zaman modern seperti sekarang, penemuan dan pengembangan bakat sedini mungkin sangat penting mengingat tuntutan sumber daya manusia yang berkualitas semakin tinggi. Oleh karena itu layanan penempatan dan penyaluran tidak hanya diperuntukan untuk sekolah menengah atau dewasa, melainkan juga untuk anak usia dini atau taman kanak-kanak.Penelitian ini dilakukan untuk mengetahui bagaimana pelaksanaan layanan penempatan dan penyaluran untuk anak usia dini di TK Insan Taqwa Surabaya berkaitan dengan kegiatan ekstrakurikuler yang dimiliki dan bagaimana peran pihak-pihak yang terlibat dalam pelaksanaannya. Penelitian ini menggunakan jenis penelitian kualitatif dengan pendekatan deskriptif. Dalam penelitian ini untuk subyek penelitiannya yaitu kepala sekolah, konselor, dan guru kelas TK A yang memberikan informasi tentang bagaimana pelaksanaan layanan penempatan dan penyaluran di TK Insan Taqwa, serta peneliti juga melakukan pengamatan terhadap seluruh siswa TK Insan Taqwa yang duduk di kelas A saat mengikuti kegiatan ekstrakurikuler.Dari hasil penelitian menunjukkan bahwa pelaksanaan layanan penempatan dan penyaluran berkaitan dengan kegiatan ekstrakurikuler sudah baik. Setiap ekstrakurikuler mendapat skor diatas 50 % dihitung dari tingkat antusias anak-anak saat mengikuti kegiatan, artinya sebagian besar anak-anak menyukai kegiatan dan layanan yang diberikan. Peran konselor dalam pelaksanaan layanan penempatan dan penyaluran adalah sebagai konsultan dan koordinator guru/ wali kelas TK A bagaimana memberikan solusi jika ditemukan masalah dalam pelaksanaan layanan dalam kegiatan ekstrakurikuler. Kata Kunci: layanan penempatan dan penyaluran , kegiatan ekstrakurikule

Model Periodik Dan Stokastik Data Pasang Surut Jam-jaman Dari Pelabuhan Panjang

The aim of this study are intended to compare periodic and stochastic tide models generated by using FFT frequencies and astronomic frequencies. The Fourier series are used to simulated peri- odic model, and the autoregressive method is employed to simulate stochastic model. 253 domi- nant FFT frequencies and 9 astronomic frequencies are used as constituent frequencies to simulate periodic models. 512 hours of data are used for the model. Results of this study present that the periodic and stochastic models using the FFT frequencies give more accurate results than periodic and stochastic models by using the astronomic frequen - cies

The aim of this study are to compare periodic and stochastic models generated by using FFT fre- quencies with periodic and stochastic models generated by using astronomic frequencies. Fourier series are used to simulated periodic model, and autoregressive method is employed to simulate stochastic model. In this study, 253 dominant FFT frequencies and 9 astronomic frequencies are used as constituent frequencies to simulate periodic models. 512 hours of data are used for the model. Results of this study present that the periodic and stochastic models using FFT frequencies give more accurate results than periodic and stochastic models using the astronomic frequencies

Breakthrough of Oscillatoria limnetica and microcystin toxins into drinking water treatment plants – examples from the Nile River, Egypt

The presence of cyanobacteria and their toxins (cyanotoxins) in processed drinking water may pose a health risk to humans and animals. The efficiency of conventional drinking water treatment processes (coagulation, flocculation, rapid sand filtration and disinfection) in removing cyanobacteria and cyanotoxins varies across different countries and depends on the composition of cyanobacteria and cyanotoxins prevailing in the water source. Most treatment studies have primarily been on the removal efficiency for unicellular Microcystis spp., with little information about the removal efficiency for filamentous cyanobacteria. This study investigates the efficiency of conventional drinking water treatment processes for the removal of the filamentous cyanobacterium, Oscillatoria limnetica, dominating the source water (Nile River) phytoplankton in seven Egyptian drinking water treatment plants (DWTPs). The study was conducted in May 2013. The filamentous O. limnetica was present at high cell densities (660–1 877 cells/mL) and produced microcystin (MC) cyanotoxin concentrations of up to 877 μg∙g-1, as determined by enzyme-linked immunosorbent assay (ELISA). Results also showed that conventional treatment methods removed most phytoplankton cells, but were ineffective for complete removal of O. limnetica. Furthermore, coagulation led to cell lysis and subsequent microcystin release. Microcystins were not effectively removed and remained at high concentrations (0.37–3.8 μg∙L -1) in final treated water, exceeding the WHO limit of 1 μg∙L-1. This study recommends regular monitoring and proper treatment optimization for removing cyanobacteria and their cyanotoxins in DWTPs using conventional methods.Keywords: cyanobacteria, removal, conventional drinking water treatmen
