PROSEDUR PEMBUATAN KERTAS KEMASAN BERBASIS BATANG AREN MENGGUNAKAN METODE SODA DI BADAN RISET INOVASI NASIONAL

Experiment on the manufacture of pulp and paper made from palm stems has been carried out. Pulp and paper production was carried out using the soda chemical method by mixing 160 grams of NaOH solution and then mixing it with 3200 ml of water and cooking it using a rotary digester machine for 4 hours at 170°C. The ratio of sample and cooking solution is 1:4. Once cooked, the dregs are washed and dried by machine. Prior to printing, the pulp is ground first until it reaches the ideal degree of fineness of a pulp, namely 250-500 ml. After that, the pulp is printed so that sheets of paper are obtained. The results of testing the physical properties of palm stem-based paper obtained base weight, thickness, oil absorption, tear resistance, moisture content, ash content, and pH with an average of 69.26 g/m2; 22,2 micron; 58.54 1000/mm; 418,8 mN; 6.29%; 2.47%. In the pH test, an average result of 6 was obtained.

Eksperimen tentang Pembuatan pulp dan kertas yang terbuat dari batang aren telah dilakukan. Pembuatan pulp dan kertas dilakukan dengan cara metode kimia soda dengan mencampurkan larutan NaOH sebanyak 160 gram lalu dicampurkan dengan air sebanyak 3200 ml dimasak menggunakan mesin rotary digester selama 4 jam dengan suhu 170°C. Perbandingan sampel dan larutan pemasak adalah 1:4. Setelah dimasak, pulp dicuci dan dikeringkan dengan mesin centrifuge. Sebelum dicetak pulp terlebih dahulu digiling hingga mencapai derajat kehalusan ideal suatu pulp yaitu 250-500 ml. Setelah itu pulp dicetak sehingga didapatkan lembaran kertas. Hasil dari pengujian sifat fisis kertas berbasis batang aren didapatkan berat dasar, ketebalan, daya serap minyak, ketahanan sobek, kadar air, kada abu, dan pH dengan rata-rata sebesar 69,26 g/m2 ; 22,2 mikron; 58,54 1000/mm; 418,8 mN; 6,29%; 2,47%. Pada
pengujian pH didapatkan hasil rata-rata sebesar 6.
