Abstract

Feed storage and packaging will be effected the quality of phisical, chemist and microbiology. Packaging are one of methode for protecting quality from damage of environment. This research to determine the effect of packaging type and storage time for broiler starter feed. This research using methode statistical Complete Randomized Desing Factorial (5x7) with three replications. The fixed variable in his research are Broiler Starter Feed. The first independent variable is the type of packaging (glass bottle, plastic bottle, aluminum foil vacuum plastic, vacuum plastic, and plastic seal) and the second independent  variable is storage (14, 169, 338, 506, 674, 842, 1010 hours). The dependent variables were research are water content test with using methode SNI.01-2891-1992 and Crude Protein testing with kjeldahl methode using AOAC 2005, Chapter 4 Item 4.2.11. method 2001.11. Analysis data by using comparison of graphic regression. The maximum results showed that aluminum foil vacuum plastic container with water content of 10,8137% and crude protein 22,4661% at 842 hours storage (± 5 weeks), water content regression are y = 0.0003x + 10,636 with R2 = 0,9085 and crude protein regression y = 0,0007x + 23,07 with R2 = 0,9477. All test results with various packaging methods and storage time conducted in this study are still in accordance with the standard of feed starter broiler SNI 8173.2.2015 with a maximum water content of 14% and crude protein at least 20%.

Abstract

ABSTRAKSalah satu proses yang tidak dapat dilewatkan untuk membuat genteng keramik adalah proses pembakaran. Proses pembakaran genteng keramik di PT XYZ menggunakan tunnel kiln dengan bahan bakar LNG. Penelitian ini bertujuan untuk mengetahui efisiensi panas atau energi pada tunnel kiln dengan terlebih dahulu menghitung neraca massa masuk dan keluar serta menghitung neraca energi masuk dan keluar. Panas masuk meliputi panas hasil pembakaran bahan bakar LNG, panas sensibel bahan bakar LNG, panas kereta masuk, panas sensibel greentile. Sedangkan untuk panas keluar meliputi panas yang terbawa oleh panas sensibel genteng keramik, panas sensibel kereta kiln, panas penguapan air dan air kristal, panas hilang akibat udara pendingin, panas hasil reaksi pembakaran, panas akibat perpindahan panas, panas keluar untuk dryer dan panas keluar chimney tunnel kiln. Metode yang digunakan adalah pengumpulan data-data pendukung diantaranya adalah volume gas LNG yang digunakan, komposisi material genteng, komposisi bagian dari tunnel kiln seperti kereta kiln, dan kapasitas panas untuk masing-masing komponen tersebut.Berdasarkan perhitungan yang telah dilakukandidapatkan nilai yang seimbang antara panas masuk dan panas keluar yaitu 14.174.025 kkal/hari. Efisiensi bahan bakar LNG dihitung dengan perbandingan antara panas yang dihasilkan dari bahan bakar dengan kebutuhan panas yang digunakan untuk satu hari proses pembakaran genteng keramik. Berdasarkan perhitungan didapat efisiensi panas tunnel kiln sebesar 98,92%.Kata Kunci : Efisiensi, Genteng Keramik, Neraca Massa, Neraca Panas, Pembakaran.  ABSTRACTOne of the process that can’t be missed to make a ceramic tile is burning. PT XYZusing tunnel kiln with LNG fuel for burning process. The purpose of this research is to know how much heat efficiency of tunnel kiln with firstly calculated mass balance and heat balance at burning ceramics tile. Data for incoming heat are obtain from calculated of heat burning fuel, sensible heat of LNG, incoming heat from kiln car and sensible heat green tile. Data for outgoing heat are obtain from calculated of sensible heat ceramic tile, sensible heat kiln car, evaporation heat of water and water crystal, heat loss because cooling air, heat of burning, heat for dryer, heat for chimney fan, and heat loss because heat transfer. The method that we used for this research are Consumption of Volume LNG, composition material tile, composition part of tunnel kiln like kiln car and heat capacity for each component. Based on the data we can obtained heat balance in and out kiln amount14.174.025 kkal/day. And the LNG fuel efficiencyis calculated by comparison between the heat generated from the fuel and the heat requirement used for one dayceramic tile burning process. After the calculation we can obtained the efficiencyis 98,92%.Keywords: Efficiency, Ceramic Tile, Mass Balance, Heat Balance, Burning.
