Abstract

The development of teaching materials for music theory courses based on this Google site uses research and development methods. This research procedure adapts the ADDIE development model, namely a development model consisting of five stages consisting of Analysis, Design, Development, Implementation, and Evaluating. The results of the research show that the Google site-based music theory I and II teaching material products are: development of Google site-based music theory I and II teaching materials using the Borg and Gall development method which consists of 7 processes, namely needs analysis, research planning, initial product development, initial field trials, revision of trial results, main product field trials, and final product revisions. The development of music theory I and II teaching materials based on the Google site is able to make students understand the material better by providing additional supporting videos and can also increase students' interest in reading because it can be accessed anytime and anywhere.

Abstract

Kolam garam merupakan kolam yang berfungsi untuk melarutkan padatan garam (NaCl) dengan pelarut air demineralisasi. Untuk membantu proses pelarutan garam, di dalam kolam garam terdapat sebuah pipa (coil) yang dialiri uap, uap akan memberikan panas secara tidak kontak langsung dengan tujuan untuk mendapatkan temperatur larutan garam yang sesuai dengan syarat spesifikasi ion exchanger serta kriteria dan standar perusahaan. Keberhasilan suatu proses pelarutan NaCl sangat dipengaruhi oleh jumlah energi (panas) yang dilepaskan oleh uap. Metode neraca energi digunakan untuk mengetahui jumlah panas yang dibutuhkan serta jumlah uap yang diperlukan untuk menghasilkan larutan garam pada kolam garam. Sehingga, berdasarkan perhitungan neraca energi diperoleh jumlah panas yang dibutuhkan untuk menghasilkan larutan garam dengan rata-rata konsentrasi 313-317 g/L pada temperatur antara 65-75oC sebesar 20.572.434,083 Kj dan diperoleh massa uap sebesar 21.459,2146 Kg.
