Abstract

Penelitian bertujuan : mendesain sistem produksi garam yang berkualitas dan diversifikasi produk garam. Penelitian mempergunakan pendekatan kualitatif dan kuantitatif dengan locus PT Garam Mas. Data dianalisis secara interaktif dan uji laboratorium. Hasil penelitian menunjukan bahwa hasil produksi garam menggunakan membran HDPE lebih putih dan bersih daripada produk garam konvensional “solar evaporation”. Garam konsumsi bermutu tinggi memiliki kandungan NaCl 97%, kadar air dibawah 0,05%, warna putih bersih, butiran kristal halus, digunakan untuk garam meja, penyedap makanan, camilan, industri sosis dan keju, serta industri minyak goreng. Garam konsumsi kelas menengah memiliki kadar NaCl 94,7-97% dan kadar air 3-7% untuk garam dapur, industri kecap, tahu, pakan ternak.Garam konsumsi mutu rendah memiliki kadar NaCl 90-94,7%, kadar air 5-10%, warna putih kusam, digunakan untuk pengasinan ikan dan pertanian. Kualitas dan kuantitas garam dipengaruhi oleh temperatur, iklim/cuaca, kekentalan air yang digunakan dan kedisiplinan petani.Penggunaan air kurang dari 23 Be berakibat produk garam tidak berkualitas. Optimasi proses pengolahan garam bahan baku menjadi garam konsumsi beriodium perlu dilakukan, sehingga memenuhi standar SNI. Sedangkan untuk membangun kelembagaan di tingkat petani diperlukan integrasi kebijakan antar stakeholder yang terkait melalui pembentukan kawasan minapolitan garam. o

Abstract

Kebutuhan garam di Indonesia dari tahun  ke tahun semakin meningkat seiring dengan bertambahnya penduduk dan perkembangan industri. Produksi garam di Indonesia sendiri masih kurang maksimal karena kualitas yang dihasilkan masih belum memenuhi standar yang disebabkan masih banyak pengotor-pengotor yang larut dalam garam. Pada penelitian ini dilakukan pembuatan garam dengan penambahan zeolit untuk mengetahui pengaruh ukuran butir zeolit, dan dosis zeolit pada mebuatan garam terhadap kadar NaCl yang dihasilkan. Hasil penelitian menunjukan pembuatan garam dengan 24oBe tanpa penambahan zeolit memiliki kadar NaCl sebesar 92,10%, kadar air sebesar 2,96%, kadar ion Ca2+ dan Mg2+ masing-masing sebesar 168,8 dan 107,50 mg/Kg. Pembuatan garam dengan penambahan zeolit dengan variasi ukuran zeolit 16, 35, 60 mesh diperoleh zeolit dengan ukuran 60 mesh menghasilkan garam dengan kualitas lebih baik yaitu memiliki kadar NaCl 96,36%, kadar air 2,29%, kadar ion Ca2+ dan Mg2+ masing-masing sebesar 138,80 dan 104,00 mg/Kg. Pembuatan garam dengan penambahan zeolit dengan variasi dosis zeolit 2,5, 3,5, 4,5 mesh diperoleh zeolit dengan ukuran 4,5 g menghasilkan garam dengan kualitas lebih baik yaitu memiliki kadar NaCl 98,25%, kadar air 1,75%, kadar ion Ca2+ dan Mg2+ masing-masing sebesar 117,60 dan 100,00 mg/Kg.

Abstract

Polymers or plastics are one of the important material and progress very quickly. The purpose of this research to modify PP with LLDPE by the usual mixing techniques to improve some of the mechanical properties of PP. The quantity of LLDPE added to PP varies in 1%, 5%, 10%, 15%, and 20%. This research also studied the properties of LLDPE/PP with the addition of silica fume. Mixing LLDPE/PP is using the Extruder Pelletizing Twin Screw Lien Chiny and mixing LLDPE/PP-Silica using the injection molding method. LLDPE/PP was tested the mechanical properties and the results are as follows: MFR test of 8.36 g/cm3, the impact strength 3.3582 kg/cm2, tensile strength of 361.599 kgf/cm2, the flexural test of 52.1 MPa, hardness 108.2 Rscale, and density of 2.8441 g/cm3. LLDPE/PP-Silica tested mechanical properties by testing the impact strength and tensile strength. The physical characteristics of LLDPE/PP and LLDPE/PP-Silica analyzed using FTIR and SEM give the results of the functional group Si-O-Si and the agglomeration of silica on the morphology of LLDPE/PP-Silica. From all the results of the mechanical test it can be concluded that LLDPE/PP 10% has the results that are considered optimum because the value of the impact strength is best from the other variations. The LLDPE/PP-Silica is not increased mechanical properties compared to LLDPE/PP. Polymers or plastics are one of the important material and progress very quickly.
