Abstract

Computer technology has developed to a very advanced measure. Calculations using complex formulas are no longer an obstacle for industry and researchers. Along with advances in computing technology, the development of fuzzy system models is also experiencing rapid progress. This paper proposes a fuzzy model combined with Vector Autoregression. The fuzzy membership function is built by selecting the median of each set to be the center of the fuzzy set. The function chosen as the membership function is Gaussian. The fuzzy Vector Autoregression model obtained was applied to the Farmer's Exchange Rate in Central Java Province. The accuracy of the model is measured based on the Mean Absolute Percentage Error. The results of model trials on FER Central Java in 2014-2020, show a pretty good forecast, namely forecasting with MAPE around 5%, and not exceeding 10%.

Abstract

Pemanfaatan teknologi informasi dalam pelaksanaan pembelajaran sebagai aktivitas evaluasi pembelajaran. Guru dapat memanfaatkan kemajuan teknologi untuk merancang soal berbasis aplikasi yang bisa dijadikan media untuk pelaksanaan penilaian. Penggunaan penilaian yang berbasis aplikasi merupakan salah satu alternatif untuk mengatasi kelemahan penggunaan penilaian tradisional yang sifatnya offline. Terdapat berbagai aplikasi yang dapat digunakan untuk mendukung kesuksesan proses penilaian di masa pandemic covid-19 seperti Kahoot dan Quizizz. Permasalahan mitra adalah: a) Guru belum optimal dalam memahami makna, manfaat, dan cara penggunaan teknologi informasi dalam kegiatan pembelajaran, b) Pengetahuan tentang teknologi informasi yang belum memadai menjadikan kemampuan guru dalam mengembangkan soal berbasis teknologi untuk kepentingan evaluasi pembelajaran perlu ditingkatkan, c) Pihak sekolah belum menyediakan media atau software komputer yang mendukung dalam pembuatan soal dengan aplikasi Kahoot dan Quizizz, d) Kurangnya narasumber yang bisa ditempati bertanya jika guru mengalami kesulitan untuk membuat soal dengan aplikasi Kahoot dan Quizizz. Berdasarkan analisis situasi yang terjadi pada saat pelaksanaan kegiatan pengabdian, tim pengabdi dapat menyimpulkan bahwa secara umum kegiatan pengabdian ini berjalan lancar dan baik. Namun tak dapat dipungkiri, ada beberapa kondisi yang menyebabkan hasil yang dicapai belum optimal. Hal tersebut disebabkan oleh waktu pelaksanaan pengabdian yang singkat serta kemampuan beberapa guru yang memang masih perlu bimbingan intensif. Selain itu kendala juga terdapat pada jaringan internet yang kurang stabil. Hal ini menyebabkan banyak waktu yang digunakan untuk menunggu proses selanjutnya.

Abstract

This research aims to describe the problem solving abilities of students at SMP Negeri 12 Palu in algebraic material in terms of learning interest. The method used in this research is a qualitative method. The results of this research show that; (1) At the stage of understanding the problem, all subjects were able to understand the problem, but subjects with moderate interest in learning did not write down their understanding. (2) In the stage of making a problem solving plan (MS), all subjects are able to make a problem solving plan. (3) The stage of implementing the problem solving plan, all subjects are able to carry out the problem solving plan (4) The stage of re-examining subjects with high learning interest (MT), and subjects with moderate learning interest (MS) re-examining their work. Meanwhile, subjects with low interest in learning (MR) did not re-examine the results of their work. The conclusion of this research is that MT subjects have high abilities in problem solving because they are able to fulfill all stages well. The MS subject is at a medium level of ability because even though he is able to complete each stage, he is not yet optimal. The MR subject is included in low ability because it is only able to complete several stages of problem solving without completing everything.
