Saat ini terjadi adanya kecendrungan penurunan kualitas air di beberapa daerah, terlebih pada daerah kawasan karst yang memiliki sistem permeabilitas tinggi yang sangat rentan terhadap pencemaran air akibat aktifitas manusia maupun perubahan alam.Tujuan penelitian adalah memetakan dan menduga kualitas air tanah dengan parameter keberadaan pencemar unsur Nitrit menggunakan metode geostatistik yang merupakananalisis statistik spasial untuk menduga data dengan prediksi dan interpolasi melalui semivariogram dan ordinary kriging pada kadar NO. Selanjutnya membandingkan model prediksi dan interpolasi yang berbeda, memetakan sebaran kadar NO 2 padasumber mata air yang menjadi kajian menggunakan Geographic Information System (GIS). Berdasarkan hasil perhitungan menggunakan metode Ordinary Kriging dengan Gaussian isotropic model diperoleh nilai RSS 2.21 dan C 0 = 0.198, C+C = 2.56, A = 9335.75. Menduga pada daerah Sumber Seribu (titik ke- 6) dengan nilai dugaan sebesar 0.89571 yang masih dikategorikan memiliki kadar nitrit yang tinggi. Kemudian modelGeographically Informasi System dengan menggunakan metode Ordinary Kriging dengan Variogram Modelling, mempunyai kriteria baik untuk menggambarkan sebaran spasial parameter kualitas air. Dengan luaran peta kontur sebaran kadar nitrit dengan daerah bitingan yang paling tinggi kadar nitritnya Studi kasus dilakukan di Kawasan Pegunungan Kendeng, Kabupaten Rembang, Provinsi Jawa Tengah.Kata Kunci : Karst, Nitrite NO 2, Ordinary Kriging, GIS.

Adapun tujuan dari penelitian ini yaitu mendeskripsi perubahan perilaku belajar siswa dalam menyampaikan informasi setelah diberikan tindakan pembelajaran menyampaikan informasi dengan teknik information gap. Penelitian ini dilakukan dengan menggunakan desain penelitian tindakan kelas. Dalam setiap penelitian tindakan, termasuk penelitian tindakan kelas, terdapat 4 aspek pokok, yaitu: (1) penyusunan rencana; (2) tindakan; (3) observasi; dan (4) refleksi. Berdasarkan data yang diperoleh penelitian ini mengalami peningkatan setelah mengikuti pembelajaran menyampaikan informasi dengan teknik information gap. Peningkatan ini dapat dilihat dari hasil tes keterampilan menyampaikan informasi siklus I dan siklus II yang mengalami peningkatan. Hasil nilai rata-rata kelas pada siklus I sebesar 68,30 berada pada kategori cukup. Hasil nilai rata-rata siswa pada siklus II sebesar 81,11 berada pada kategori baik. Selisih nilai rata-rata antara siklus I dan siklus II sebanyak 12,81. Jadi, peningkatan keterampilan menyampaikan informasi antara siklus I dan siklus II sebesar 18,75%.

The abundant of information on the internet has become a competitor for libraries as information service providers. Therefore to survive and thrive, the libraries must change and adopt to a rapidly evolving external environment. Understanding user information seeking behaviour is very useful for redesigning various services that suit to user needs. The objectives of this study were: 1). To analyze the characteristics of digital natives and digital immigrants of IPB University students related to their information seeking behaviour; 2). To develop a model of information seeking behaviour of both digital natives and digital immigrants of IPB University students based on structural equation modeling. The study was mainly quantitative and questionnaire was designed to study students’ information-seeking behaviour. The findings showed that the dominant behaviours and preferences of digital natives in their information seeking behaviour were influenced by environmental variables, especially the availability of information. For the information seeking behaviour variables of students, the dominant indicator were asking for printed and digital information to the lecturer. While for immigrant digital students their information seeking behaviour were dominantly influenced by environmental variables, especially the availability of information. The indicators for information seeking behaviour of digital immigrant student were dominated by asking printed information to friends, and requesting digital information to the lecturer. The success of getting information is dominant in the speed-of-getting-information indicator, both for digital natives and digital immigrant students.

This study examines the value relevance of accounting information. This study investigates whether accounting information has impact on the share prices. In addition, it examines whether earnings management moderates the value relevance of accounting information to the market. Accounting information in this study consists of earnings, book value of equity, and cash flows, and the earnings management is proxied by discretionary accruals measured using the performance-adjusted modified Jones model. Using time series analysis, there are 98 samples of listed manufacturing corporations used in this study during 2014 which is the period of this study. The results show that earnings, book value of equity, and cash flows simultaneously affect the share prices, meaning that accounting information is value relevant to the market, although there is evidence that partially, only cash flows have impact on share prices. This study also found that the presence of earnings management weakens the value relevance of earnings. To some extent, the results indicate that earnings management eliminates the value relevance of earnings and cash flows.
