Abstract

Karet (Hevea brasiliensis) menjadi salah satu komoditas unggulan sektor perkebunan Indonesia. Pemanfaatan karet biasanya hanya difokuskan pada pengambilan getah pohon, sedangkan biji karet tidak mempunyai nilai ekonomis selain sebagai benih generatif pohon karet, sehingga biji karet belum termanfaatkan secara optimal dan dianggap sebagai limbah. Penelitian bertujuan untuk menghasilkan berbagai produk ramah lingkungan dengan mengoptimalisasi biji karet melalui proses biorefinery yaitu biodiesel, briket, dan pupuk organik cair. Proses mengolah biodiesel dari biji karet yaitu dengan mengepres biji karet yang sudah dilepaskan dari cangkangnya, dilanjutkan dengan proses degumming dan reaksi transesterifikasi. Proses tersebut menghasilkan limbah cangkang biji karet dan ampas biji karet. Cangkang biji karet diolah menjadi briket dengan proses pengarangan, pengayakan, pencampuran bahan, pencetakan briket, dan pengeringan. Proses pengolahan ampas biji karet menjadi pupuk cair organik yaitu dengan menambahkan larutan EM4 dan kotoran ayam, kemudian difermentasi selama 3 minggu. Hasil dari penelitian ini yaitu minyak biji karet yang berpotensi menjadi biodiesel, briket, dan pupuk organik

Abstract

This study aims to determine the effect of students' numeracy skills by using the jaritmatika method and the Pythagorean multiplication table on student learning outcomes significantly in mathematics lessons on student multiplication operations. The method used in this research is the quasi experimental method of experimental research which is basically the same as cause-and-effect research but is carried out using pseudo-experimental methods. This research was conducted at SDN Sungai Jingah 5 with saturated sampling of grade III. The results showed that the numeracy skills of experimental grade students using the jaritmatika method and tables can be seen from the average results of 82.13 are in the "Very Good" qualification, while the numeracy skills of control grade students using the interactive discussion method 73.87 are in the "Good" qualification. Based on the calculation with the Independent Simple T Test "T Test" with asymp, Sig (2-tailed) is 0.041, because 0.041 <0.05 then H 0is rejected and H ais accepted so it can be concluded that there is a significant difference in the learning outcomes of the ability to count multiplication of the experimental grade (using the jaritmatika method and table) and the control grade (using interactive discussions). The implication of this research can be used as an alternative method of learning mathematics calculation for elementary school students.
