Abstract

The background of the research is that based on initial observations at school, it is known that a nature of science oriented module has never been developed due to time constraints due to the many administrative duties of teachers at school. In fact, one way to increase student literacy is based on the nature of science by developing appropriate and good teaching materials. One of the teaching materials developed is in the form of a module. The aim of this research is to determine the implementation and effectiveness of using nature of science oriented modules to increase student literacy. The research method uses a mixed method with an exploratory sequential design. The sample used was taken purposively as many as 60 students of class X Science at SMA Negeri 1 Ciwaru, with 30 students as the control class and 30 students as the experimental class. Data collection techniques include interviews, module validation sheet checklists, scientific literacy tests, questionnaires and documentation. Data analysis used descriptive analysis, mean difference test, and gain index. The results of this research concluded that: (1) The effectiveness of implementing the Nature of Science (NOS) oriented module to increase scientific literacy in environmental pollution material in class tall. (2) Students' scientific literacy skills in environmental pollution material increase through the implementation of the Nature of Science (NOS) oriented module to increase scientific literacy as evidenced by the significant difference in mastery of concepts in the experimental class and the control class with a probability value (p) of 0.000<0.05 , and the experimental class's normalized gain index of 0.35 (medium category) is higher than the control class with a gain index of 0.17 (low category).

Abstract

Farmers in Kananga Village still use chemical fertilizers, this has led to farmers' dependence on chemical fertilizers. Farmers can make their own organic fertilizer, but farmers introduce time for the composting process to the materials that will be used as organic fertilizer. Farmers need technology that can accelerate the process of composting organic matter, and farmers also need to know the effect of chemical fertilizers on reducing soil fertility. Therefore, there is a need for community service activities that train and assist farmers to use organic fertilizer switching, and introduce Effective Microorganism 4 (EM4) technology in making fertilizer or EM4 in agriculture. EM4 is a technology for cultivating a mixture of microorganisms suitable for plant growth in agriculture. These microorganisms are bacteria that can be grown independently by the community, especially farmers in Kananga Village. This PkM activity is designed as an effort to reduce farmers' dependence on chemical fertilizers and invites farmers to use EM4 technology in making fertilizers. The results of this PkM also hope to make the community in Kananga Village more independent by being able to produce their own agricultural products in order to increase the competitiveness of the village. In addition, the PkM training and mentoring program is the commitment of the University of Kuningan in improving community empowerment. Abstrak Petani di Desa Kananga masih menggunkan pupuk kimia, hal ini menimbulkan kergantungan petani terhadap pupuk kimia. Petani dapat membuat pupuk organic sendiri, namun petani mengeluhkan lamanya waktu untuk proses pengomposan pada bahan bahan yang akan dijadikan pupuk organic. Petani perlu teknologi yang dapat mempercepat proses pengomposan bahan organic, dan petani juga perlu mengetahui dampak yang akan ditimbulkan dari pupuk kimia bisa merusak kesuburan tanah. Oleh karena itu kegiatan pengabdian masyarakat yang melatih dan mendampingi petani agar beralih menggunakan pupuk organic, serta mengenalkan teknologi Effective Microorganism 4 (EM4) dalam membuat pupuk ataupun EM4 dalam pertanian. EM4 ini merupakan teknologi dalam mengkultur campuran dari mikroorganisme yang menguntungkan untuk pertumbuhan tanaman dalam usaha pertanian. Mikkroorganisme tersebut merupakan bakteri-bakteri yang dapat dibibit secara mandiri oleh masyarakat khusunya para petani di Desa Kananga. Kegiatan PkM ini merupakan upaya menghilangkan ketergantungan petani terhadap pupuk kimia serta mengajak petani untuk menggunakan teknologi EM4 dalam membuat pupuknya. Hasil PkM ini juga berharap dapat menjadikan masyarakat di Desa Kananga menjadi semakin mandiri dengan mampu menghasilkan produk pertanian sendiri guna meningkatkan daya saing Desa. Program PkM ini melatih dan mendampingi masyarakat merupakan Visi Universitas Kuningan kearah pemberdayaan masyarakat.

Abstract

The low level of students ' scientific literacy abilities can be caused by learning habits that are still conventional . Developing digital- based learning media is a good learning media to use in learning in the era of the industrial revolution 4.0 and is believed to be capable to increase students ' scientific literacy . The aim of this research is to develop contextual visual media that can increase students ' scientific literacy . The method used in this research uses the ADDIE model developed by Dick and Carry . The results of the research is in the form of contextual visual media which was developed in five stages , namely analysis was carried out by observing and interviewing school principals and subject teachers , design was carried out by making stories boards , at the development stages validation was carried out by material experts and learning design experts , implementation was carried out in the experimental class , and the evaluation stages was carried out by improving the visual media developed according to input from the validator team . The validity test results are in the very good category , so the visual media developed is suitable for use in research . Based on the t test results of 0.001, these results indicate that the hypothesis is accepted , so it can be concluded that there is an increase in scientific literacy after learning activities using the developed contextual visual media.
