Abstract

Bahan ajar diperlukan dalam pembelajaran sains dan dapat dijadikan acuan peserta didik untuk memiliki kemampuan multidisipliner dan berpikir tingkat tinggi. Salah satunya adalah Lembar Kerja Peserta Didik (LKPD). Akan tetapi, kemampuan guru dalam menyusun LKPD masih belum optimal. Apalagi menggunakan pendekatan yang dapat meningkatkan kemampuan berpikir tingkat tinggi (HOTS) peserta didik, seperti STEM. Pengabdian kepada Masyarakat ini bertujuan untuk memberikan wawadan dan mendampingi guru sains dalam menyusun LKPD STEM for HOTS. Kegiatan Pengabdian kepada Masyarakat (PkM) ini menggunakan pendekatan Participatory Action Research (PAR) dengan tahapan Diagnose, Act, Measure dan Reflect. Kegiatan ini berorientasi sosial dan melibatkan kerja sama para praktisi dan partisipasi masyarakat untuk memberikan kontribusi pada perubahan masyarakat. Bentuk kegiatannya adalah melaksanakan pelatihan dan pendampingan kepada guru sains di Kalimantan Selatan untuk menyusun LKPD STEM for HOTS. Subjek PkM ini adalah guru mata pelajaran Biologi, Fisika dan Kimia dari berbagai sekolah di Banjarmasin dan sekitarnya. PkM dilaksanakan pada bulan Agustus 2020 saat pandemic Covid-19 secara offline dan dihadiri oleh 25 peserta yang merupakan guru dan calon guru sains di sekitar Banjarmasin. Hasil PkM menunjukkan bahwa guru dan calon guru sains dapat terlatih dalam menyusun LKPD berbasis STEM for HOTS. Dengan adanya pelatihan ini, guru dan calon guru sains dapat memahami dan mengaplikasikan variasi pendekatan pembelajaran dalam penyusunan LKPD untuk diterapkan dalam pembelajaran di sekolah masing-masing. Dengan demikian, pelatihan penyusunan LKPD berbasis STEM for HOTS dapat terlaksana dengan baik dan mewujudkan bahan yang inovatif.Teaching materials are needed in science learning. One of them is Student Worksheets (LKPD). However, the teacher's ability to prepare LKPD is still not optimal. Moreover, using an approach that can improve students' higher-order thinking skills (HOTS), such as STEM. This Community Service (PkM) aims to guide and assist science teachers in preparing STEM LKPD for HOTS. This PkM activity uses a Participatory Action Research (PAR) approach with the stages of Diagnose, Act, Measure, and Reflect. This activity is socially oriented and involves the collaboration of practitioners and community participation to contribute to societal change. The form of its activities is to conduct training and mentoring for science teachers in South Kalimantan to prepare STEM LKPD for HOTS.

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.
