Metode yang digunakan adalah model pengembangan prototyping dengan empat langkah yaitu: komunikasi, perencanaan dan pemodelan sistem secara cepat, membangun purwarupa, dan terakhir penerapan, evaluasi dan umpan balik. Hasil penelitian menunjukan bahwa purwarupa sistem pemantauan kondisi air yang dibangun dapat digunakan memantau beragam kondisi kekeruhan air sesuai dengan standar kondisi kekeruhan air, mulai dari kondisi air jernih (400 NTU). Hasil pemantauan tersebut kemudian disimpan sebagai riwayat dan divisualisasikan dalam aplikasi berbasis website, dan setiap perubahan kondisi air kemudian dapat dikirimkan kepada petugas dalam bentuk notifikasi SMS secara otomatis. Meskipun masih dalam skala laboratorium, purwarupa sistem pemantauan kondisi air yang dibangun sudah siap diterapkan pada lingkungan sebenarnya dengan memperhatikan penempatan sensor-sensornya. Continuous monitoring of water conditions and realtime using a computerized system is indispensable for drinking water companies. It is aimed at monitoring the turbidity and altitude of water in the water shelter to conform to the standards set. This research aim is to perform the design of the monitoring system of turbidity conditions and water levels in the body of Bone Bolango PDAM. The methods used are models of prototyping development with four steps are communication, planning, and system modeling quickly, building prototypes, and last application, evaluation, and feedback. The results showed that the prototype of the water condition monitoring system that was built can be used to monitor various turbidity conditions by accordance with water turbidity conditions, ranging from clear water conditions (< 100 NTU), murky water conditions (101-400 NTU), and very cloudy water conditions (> 400 NTU). The monitoring results are then saved as history and visualized in the website-based application, and any changes in the water condition can then be sent to the officer in the form of SMS notification automatically. Although still in the laboratory scale, the prototype of the built-in water condition monitoring system is ready to be applied to the actual environment concerning its sensor placement.

Abstract

Penelitian ini bertujuan mengevaluasi kesesuaian strategi bisnis dan strategi teknologi informasi (TI) di Universitas Negeri Gorontalo (UNG) dengan best practice COBIT 5. Peneliti melakukan pengamatan bagaimana UNG melakukan perencanaan strategi bisnis dan TI kemudian dibandingkan dengan best practice COBIT 5. Metode yang digunakan dalam penelitian ini adalah kualitatif yang meliputi wawancara dengan pihak yang berkepentingan dan studi dokumen terkait strategi bisnis dan strategi TI. Model yang dipakai yaitu: COBIT 5 pada domain APO proses APO02 yang terdiri dari 31 aktivitas dan, SCAMPI (Standard CMMI Appraisal Method for Proses Improvement) sebagai metode penilaian. Hasil penelitian menunjukan bahwa aktivitas penyelarasan strategi bisnis dan strategi TI di UNG telah mendekati proses aktivitas keselarasan strategi bisnis dan strategi TI pada COBIT 5. Hal penting lainnya yang ditemukan dalam penelitian ini adalah meskipun aktivitas perencanaan penyelarasan strategi bisnis dan strategi TI di UNG telah hampir medekati best practice COBIT 5 namun, tidak menjamin dalam keseluruhan aktivitas bisnis dan TI di UNG selaras, hal tersebut dibuktikan dengan ditemukan 3 proses yang memiliki kelemahan utama karena tidak terdapat aktivitas atau bukti praktik-praktik yang dilaksanakan merujuk pada COBIT 5. This study aims to evaluate the suitability of business strategies and Information Technology (IT) strategies at Universitas Negeri Gorontalo (UNG) with COBIT 5 best practices. Researchers observe how UNG is planning business strategies and IT then compared with the best COBIT practice 5. The method used in this study is qualitative which includes interviews with interested parties and document studies related to business strategies and IT strategies. The model used is COBIT 5 in the APO domain APO02 process which consists of 31 activities and, SCAMPI (Standard CMMI Appraisal Method for Process Improvement) as a valuation method. The results showed that the alignment of business strategy and IT strategy in UNG had approached the process of alignment of business strategy and IT strategy in COBIT 5. Another important thing found in this study was that planning activities for aligning business strategies and IT strategies at UNG had almost approached. COBIT 5 best practice, however, does not guarantee that overall business and IT activities at UNG are aligned, this is evidenced by the finding of 3 processes that have major weaknesses because there is no activity or evidence of practices carried out referring to COBIT 5.
