Abstract

Design of a monitoring system for the quality and capacity of water absorption wells type Aquifer Storage and Recovery (ASR) using wireless system has been conducted by monitoring changes in well water surface level, the rate of change of fl ow capacity (fl ow rate) and changes in water quality (turbidity). In order to determine the performance of the system, we conducted several tests by placing a sensor and a receiver by two different distances, i.e. the distance of 1 m (short distance) and the actual condition of 35 m (long distance). The results of the system design consist of a wireless monitoring system hardware and data acquisition system software able to display online and in real time. Based on the test results, the value of the total error due to repeatability and linearity for flow rate sensors, water level and turbidity using short-distance wireless systems, are respectively 2.77%, 1.77% and 3.65%. As for the wireless remote system, they are respectively 1.43%, 1.83% and 2.43%. So, the monitoring system of groundwater quality and capacity for infi ltration well using the wireless system can be applied to the actual distance of 35 m, because the error rate due to the infl uence of the distance between the transmitter and the receiver is relatively small, and even better when compared with the short distance ( 1 m).

Abstract

Pendidikan yang bermutu adalah Pendidikan yang mampu mengembangkan kemampuan, membentuk karakter dan peradaban bangsa. Oleh karena itu harus dikembangkan dalam pendidikan disekolah maupun pesantren nilai-nilai keimanan, ketaqwaan, akhlak mulia, kesehatan, ilmu, kecakapan, kreativitas, kemandirian, demokrasi dan tanggung jawab pada anak didik dan seluruh stakeholders pendidikan. Kondisi Saat ini kebanyakan sekolah hanya mengembangkan aspek- aspek pendidikan secara dangkal: dimensi kognitif (hanya menghafal); dimensi ketrampilan (mekanistik); dimensi nilai tidak terurus dan tidak mendalam; dimensi hubungan (ranah interaktif ) tidak tergarap. Padahal seharusnya sekolah berkualitas mampu mengembangkan dimensi kognitif (menguasai pengetahuan sesuai dengan bakat, minat siswa/i nya). Penelitian ini menggunakan kualitatif dengan pendekatan deskriftif analisis. Melihat fenomena tersebut penulis mencoba untuk menawarkan sebuah konsep, implementasi dan perkembangan pendidikan Islam dalam bingkai manajemen strategik, dalam proses pembelajaran di sekolah formal maupun non formal dengan tujuan membentengi siswa diera globalisasi agar tetap berpegang pada nilai-nilai qur?an, hadist, ijma? dan qiyas. Inti dari sebuah konsep manajemen strategik dalam pendidikan Islam memang merupakan hal yang baru sehingga harapan besar pada tulisan ini dapat digunakan di dunia pendidikan Islam yang lebih luas serta lebih mengefektifkan pengalokasian sumber daya yang ada dalam rangka mencapai tujuan pendidikan nasional. Salah satu caranya adalah dengan menggunakan teknik analisis SWOT. Jadi mutu lulusan pendidikan Islam tidak dipandang sebelah mata, justru sangat besar peranannya di lingkungan masyarakat. pendidikan Islam sesungguhnya adalah solusi bagi penyakit yang menimpa manusia modern. Pendidikan Islam adalah pendidikan yang dibangun atas dasar fitrah manusia. Yang senantiasa bertujuan menumbuhkan kepribadian total manusia secara seimbang melalui latihan spiritual, intelektual, rasional diri, perasaan dan kepekaan tubuh manusia.
