Abstract

NTB is one of the provinces that experienced significant economic growth. In 2017 the economic growth of NTB Province reached 7.1% from 5.6% of national economic growth. Of course this comes from various fields, one of which is the agricultural sector, namely processed products of water sap (palm sugar). The NTB sugar production center is a national superior product commodity with good production quality (NTB in Figures, 2018). One of the villages which is a commodity of palm sugar is Kekait Daye Hamlet. However, this condition is not supported by the earthquake during August-September 2018 which caused the economic paralysis in NTB. The purchasing power of the people has decreased dramatically, the production process of processed products for the people must be stopped and even out of business. So that it causes the production process to weaken because people have to lose production sites and equipment in the manufacture. Plus the products produced are still in the form of general products such as ant sugar and briquette sugar which if sold have prices that are not too high while on the one hand there needs to be innovation to improve the economy of the community. So the researchers made an innovation in the diversification of processed water sap products that have high economic value. This research aims to create processed products of water diversified sap which have high economic value, good packaging and good quality. The method of this research starts from the preparation of tools and materials, making products and socializing to the public. The results of the study were the creation of a diversified process of palm water products in the form of palm sugar, palm coffee , and sugar palm chocolate. Keywords: diversification, economic, kekait, palm

Abstract

The ability to solved problems is an important element in learning mathematics. But in reality at SMPN 13 Mataram this ability still low with a percentage of 70% of students having low problem solving abilities. The reason is teachers tend use same learning methods and students also not know how to optimize their own potential in learning. One way to make learning mathematics effective is by knowing learning styles used by students. This study aims to describe the problem-solving abilities claass VIII at SMPN 13 Mataram based on learning styles. The type of research used is qualitative research with research instruments namely problem solving ability tests, learning style questionnaires and interviews. The results obtained from 28 students were students with 12 students in the visual style category, 15 auditory students and 1 student with a kinetic learning style. The conclusion from the research results is that from the four stages of problem solving based on the theory of polya. , The visual learning style is able to complete the four stages very well. Auditory learning styles can only complete the 3 stages well and do not do the re-checking stage. In the kinetic learning style, it can only solve one problem and does not carry out the rechecking stage. The main difference between these three learning styles is the accuracy in problem processing.

Namun kenyataannya di SMPN 13 Mataram kemampuan tersebut masih rendah dengan persentase 70% siswa memiliki kemampuan pemecahan masalah yang rendah. Salah satu cara mengoptimalkan pembelajaran matematika dengan mengetahui gaya belajar yang digunakan siswa. Penelitian ini bertujuan untuk mendeskripsikan kemampuan pemecahan masalah di SMPN 13 Mataram kelas VIII ditinjau dari gaya belajar. Jenis penelitian yang digunakan yaitu penelitian kualitatif dengan instrumen penelitian yaitu tes kemampuan pemecahan masalah, angket gaya belajar dan wawancara. Hasil yang didapatkan dari 28 siswa terdapat siswa dengan 12 siswa kategori gaya visual, 15 siswa auditori dan 1 siswa dengan gaya belajar kinetik. Kesimpulan dari hasil penelitian yaitu dari empat tahapan pemecahan masalah berdasarkan teori polya, gaya belajar visual mampu menyelesaikan empat tahapan dengan sangat baik. Gaya belajar auditori hanya dapat menyelesaikan 3 tahapan dengan baik dan tidak melakukan tahapan memeriksa kembali. Pada gaya belajar kinetik hanya dapat menyelesaikan satu masalah dan tidak melakukan tahapan memeriksa kembali. Perbedaan utama dari ketiga gaya belajar ini yaitu ketelitian pada pengerjaan soal. Kata kunci: kemampuan pemecahan masalah, gaya belajar, SMPN 13 Mataram
