Abstract

Danau Siombak memiliki luas 40 hektare dengan kedalaman 12 meter terletak  di Kelurahan  Payah Pasir Kecamatan Medan Marelan Sumatera  Utara. Saat ini Danau Siombak difungsikan sebagai daerah resapan air   pengendali banjir, area penangkapan ikan dan  tambak penduduk sekitar  serta menjadi tempat wisata. Tetapi  akhir tahun 2019  kualitas air   Danau Siombak sangat buruk dikarenakan ratusan bangkai  babi yang dibuang di perairan danau tersebut. Akibatnya banyak ikan  dan hasil tambak yang mati, bau busuk serta  matinya industry wisata. Oleh karena  itu penelitian ini bertujuan merancang sebuah  sistem  yang dapat memonitoring  dan memberikan informasi mengenai kualitas air Danau Siombak  dengan parameter  yang dimonitoring yaitu tingkat kekeruhan air, suhu, tingkat keasaman (pH), oksigen terlarut (DO) dan padatan terlarut (TDS).   Metode yang digunakan pada penelitian ini aplikasi demonstrasi. Dari  2 pengujian  yang telah dilakukan diketahui  untuk pengujian implementasi skema rangkaian menunjukan tingkat ketepatan sensor   mencapai 100% sedangkan pengujian sistem secara keseluruhan mencapai 90%.

Abstract

In this study Brute Force and Stemming algorithms are combined in the mashdar word search system. The purpose of this study is to facilitate the user in finding the basic words of a word along with its changes based on the review of basic words to mashdar. The data used in this study were obtained from 50 books of Tashrif by Sheikh Hasan bin Ahmad. The results of the study by combining brute force and stemming algorithms in mashdar search with a test sample of 15 words obtained an accuracy value of 78.9%, 86.6% precission, 84.6% recall and 66.6% specificity.

Abstract

In improving the education and teaching process by lecturers in tertiary institutions, learning is carried out using Blended Learning technology. Blended learning is a collaboration and / or a combination of learning that has a traditional nature (learning by doing face-to-face) and learning by utilizing technology or what is referred to as e-learning. The application of Blended Learning technology in universities in Riau Islands province has been carried out in several universities in the city of Batam. Previous research states that there are problems in the application of Blended Learning technology. This study examines how the Acceptance of Blended Learning Technology by Students in the city of Batam with the Unified Theory of Acceptance and use of Technology (UTAUT) method. In carrying out this research activity a quantitative approach is used with a causalistic explanatory research research design. The results of this study reveal that business expectations, performance expectations, social influence, and facility conditions together affect the independent variable Blended Learning Technology Acceptance. This shows that the overall acceptance of Blended Learning Technology among students has been well received
