Analisis Kadar Magnesium dan Kalium pada Garam Rich Minerals | Author : Ary Giri Dwi Kartika, Wiwit Sri Werdi Pratiwi, Novi Indriawati, Onie Wiwid Jayanthi | Abstract | Full Text | Abstract :Pemenuhan sumber mineral dalam makanan yang seimbang mampu menunjang tercapainya kondisi tubuh yang sehat. Garam rich minerals selain digunakan sebagai bumbu dan penyedap makanan, merupakan salah satu sumber mineral yang dibutuhkan oleh tubuh. Kombinasi Kandungan NaCl dan berbagai mineral lainnya yang tidak dihilangkan dalam proses produksi garam rich minerals mampu menjaga keseimbangan elektrolit dalam tubuh demi mempertahankan komposisi keseluruhan fungsi tubuh. Pada penelitian ini, garam rich minerals dihasilkan dari proses penguapan air laut bebas kontaminasi dan tidak menghilangkan berbagai mineral lainnya yang terkandung di dalam air laut. Setiap 1000 ml air laut yang direbus menghasilkan rata-rata 34 gram kristal garam. Data analisis kimia menunjukan kadar air sebesar 5%, NaCl sebesar 88% ; kalium sebesar 0.024% serta magnesium sebesar 0.476%. Dari data tersebut garam rich minerals memenuhi SNI syarat mutu garam gurih.

Analysis of Magnesium and Potassium Content in Rich Minerals Salt
ABSTRACT
The Fulfillment of mineral resources in balanced food can support the achievement of a healthy body condition. Rich minerals salt is one of the sources of minerals needed by the body beside it being used as a food seasoning and flavoring. The combination of NaCl content and various other minerals that are not removed in the production process of rich minerals can maintain the electrolyte balance in the body to maintain the overall composition of body functions. In this study, rich mineral salts were produced from contamination-free seawater evaporation processes and did not eliminate various other minerals contained in seawater. Every 1000 ml of boiled sea water produces an average of 34 grams of salt crystals. Chemical analysis data showed a water content of 5%; NaCl 88%; potassium 0.024% and magnesium 0.476%. From that data, rich minerals salt fulfill savory salt quality requirements by SNI.

| Perencanaan Produksi Proses Pembuatan Alat Musik Flute | Author : Indri Hapsari, Azizah Al Habshe, Amelia Santoso | Abstract | Full Text | Abstract :PT. X di Pasuruan merupakan perusahaan industri manufaktur yang memproduksi alat-alat musik seperti, piano, keyboard, gitar dan bass, drum, alat tiup seperti flute, pianika, dan lain-lain. Tingginya jam lembur membuat penelitian ini terfokus pada parts process department section body process khusus alat musik flute. Produk jadi flute terdiri dari 3 part yang berupa flute head, flute body, dan flute foot yang diproduksi di parts process department section body process khusus memproduksi flute head, flute body, dan flute foot. Fluktuatifnya permintaan konsumen membuat pihak manajemen kesulitan untuk meramalkan berapa jumlah flute head, flute body, dan flute foot yang harus diproduksi secara tepat. Apabila hasil peramalan yang kurang tepat tersebut mengakibatkan adanya ketidaksesuaian antara jumlah permintaan dengan kapasitas produksi flute head, flute body, dan flute foot di PT. X. Oleh karena itu perlu adanya perencanaan produksi usulan agar dapat memenuhi permintaan sesuai dengan kapasitas yang dimiliki PT. X dan meminimumkan total biaya yang dikeluarkan. Perencanaan produksi usulan yang dilakukan menggunakan metode mix integer linear programming dengan bantuan software Lingo 11.0. Total biaya yang dikeluarkan untuk perencanaan produksi metode perusahaan sebesar Rp35.766.639.589 sedangkan, metode usulan sebesar Rp35.687.132.806. Metode usulan dapat melakukan penghematan total biaya produksi sebesar 0,22% yaitu Rp79.506.783.

Production Planning of Flute Musical Instrument Production Process
Abstract— PT. X in Pasuruan is an industrial manufacturing company that produces musical instruments such as, piano, keyboard, guitar and bass, drums, flutes, pianica, etc. Highly overtimes is the reason why this research focuses on parts process department section body process specific to a flute. The flute consist of 3 parts which are flute head, flute body, and flute foot that produces on parts process department section body process. Fluctuatively consumer request had caused confusion for the management to accurately estimate the number of flute head, flute body, and flute foot to be produced. If the result of forecasting is not matching, therefore there is a difference in a number of orders and production capacity of flute head, flute body, and flute foot at PT. X Hence, there should be a production estimate plan to overcome the problem relating to the capacity at PT. YMPI at the same time minimizing costs. Mix integer linear programming method was used as a suggestion with the help of software Lingo 11.0. The total cost spent on the company method is Rp35.766.639.589, while the proposed method is Rp35.687.132.806. The proposal method of production and planning managed to cut the cost by 0,22% which is Rp79.506.783.
