Penentuan Waktu Pembangunan Pabrik Semen Baru Untuk Antisipasi Shortages Di Indonesia

The capacity expansion through a new plant is a strategic issue for cement industry. Determining the right time for expansion is a critical issue since built too fast means the cement manufacturer will facing overproduction risks, while too slow the cement manufacturer may lose their potential markets. We discuss the situation dealt by cement industry to determine when this industry requires additional capacity. We use the concept of equilibrium supply-demand to develop a surplus/shortages map of Indonesian cement industries. The result indicates that the cement industry will experience shortages in 2014 with quantity around 397 thousands tons (for 90% utilization assumption). Development of new cement plant should be started from 2011 with an assumption it require 3 years construction period

Penerapan Metode Karya Wisata untuk Meningkatkan Motivasi dan Hasil Belajar pada Siswa Sekolah Dasar

Latar belakang penelitian ini yaitu kurangnya motivasi siswa pada mata pelajaran IPS karena sumber belajar yang digunakan guru kurang tepat dalam proses pembelajaran.

Instrumen yang dilakukan pada penelitian ini terdiri dari lembar observasi yang terdiri dari lembar aktivitas guru dan aktivitas siswa, lembar tes dan angket. Teknik analisis keempat instrument tersebut data yang dikumpulkan berupa data kuantitatif. Dalam hal ini peneliti menggunakan analisis statistik deskriptif dengan cara mencari nilai persentase keberhasilan dan rata-rata.Prosedur dalam penelitian tindakan ini terdiri atas tiga siklus. Data dalam penelitian ini pada setiap siklus mengalami peningkatan. Hipotesis pada penelitian ini adalah pada saat pembelajaran dengan menerapkan metode karya wisata, maka dapat meningkatkan motivasi belajar siswa pada pembelajaran IPS siswa kelas IV SDN Kelurahan II Nganjuk. Kesimpulan dari penelitian ini adalah penerapan metode karya wisata dapat meningkatkan motivasi belajar siswa pada mata pelajaran IPS kelas IV SDN Kelurahan II Nganjuk

In other words, the model was effective to improve the quality of teachers\u27 performance and students\u27 achievement

Nursing Informatics System in Health Care Delivery

Background: The use of information technology in nursing care services is very important. The development of nursing information systems is oriented towards improving the quality of nursing care. Objective: This paper aims to present a complex understanding of nursing information systems and relates them to the terminology of nursing care that can be used in health services. Nursing information systems in health services consist of clinical settings and community settings. Method: This paper presented with a method of literature study through searching database in SCIENCE DIRECT and ELSEVIER of scientific journal. We searched by identifying relevant journals. This Paper presents 39 journals from 2011 - 2016. Results: Nursing Information Systemis a combination of nursing, information, and computer science to manage and process data into knowledge to use in nursing practice. We introduce a nursing information design system using NNN Linkage terminology. Nursing Information System consists of standards of nursing care, standard operating procedures, calculation of nurse credit values, list of nursing diagnosis, list of nursing interventions, implementation reports, statistical reports, and nursing care resumes. Conclusion: The use of information systems in nursing care services provides an overview of knowledge and innovation in the use of information technology in providing nursing care services.
