The impact of this 4.0 era is that data is growing and can be collected very easily and then reprocessed to obtain information. One of the search engines for various data and information that is often used is Google, causing a high search intensity and will further impact on increasing the amount of data generated by search engines. Google Trends is one of the official websites from Google that reflects or takes pictures of events in society based on search keywords. The search keyword that will be studied in this article is “Sarung Wadimor”. Therefore, the purpose of this research is to forecast the search trend for the keyword "Sarung Wadimor" which is interesting because the resulting time series data pattern shows a recurring pattern due to the effect of calendar variations which are thought to be related to the month of Ramadan. Forecasting modeling uses Autoregressive Integrated Moving Average (ARIMA) and Time Series Regression (TSR). The goodness of the model used in this article is the Mean Square Error (MSE), Root Mean Square Error (RMSE), and Symmetric Mean Absolute Percentage Error (SMAPE). Based on the results of the analysis, using three goodness-of-fit measures shows that the TSR model with the Calendar Variation of Ramadan + Month Periods has smaller MSE, RMSE, and SMAPE values than the other models with goodness-of-fit values of 88.602, 9.413, and 26.950, respectively. Forecasting results for the next 6 periods show that the search trend for the keyword "Sarung Wadimor" tends to decrease, this is because the month of Ramadan is still quite far in 2023.
Perguruan Tinggi Negeri (PTN) adalah salah satu jenjang studi tujuan dari siswa SMA setelah lulus. Lembaga yang menjadi penyelenggara tes masuk perguruan tinggi bagi calon mahasiswa baru yaitu Lembaga Tes Masuk Perguruan Tinggi (LTMPT). Berdasarkan data LTMPT Tahun 2021 yang dapat diakses di top-1000-sekolah.ltmpt.ac.id, 5 peringkat peraih nilai Ujian Tulis Berbasis Kompetensi secara nasional tertinggi berasal dari SMA/sederajat dari Jawa. Sedangkan SMA/sederajat di Kota Samarinda menempati peringkat mulai dari 419. Hal ini dikhawatirkan menurunkan daya saing siswa/i Kota Samarinda untuk diterima di perguruan tinggi negeri. Oleh karena itu, dalam pengabdian masyarakat ini akan dilakukan Pelatihan Tes Kemampuan Akademik (TKA) Bidang Matematika untuk siswa kelas 12 SMA Kota Samarinda. Dengan harapan untuk memberikan pengalaman dan pemahaman Tes Kemampuan Akademik kepada Siswa/i kelas 12 Kota Samarinda. Kota Samarinda dipilih karena kemudahan akses dan siswa kelas 12 SMA dipilih karena termasuk peserta didik tingkat akhir. Metode pelatihan yang digunakan adalah tatap muka, ceramah, latihan dan diskusi. Peserta diberikan tes awal sebelum pelatihan dan peserta diberikan tes akhir setelah pelatihan. Data tes awal dan tes akhir dianalisis menggunakan statistika deskriprif dan uji beda rata-rata. Hasilnya terdapat perbedaan rata-rata pada tes awal dan tes akhir, dan rata-rata tes awal < rata-rata tes akhir. Artinya tim pengabdian kepada masyarakat berhasil memberikan pengalaman dan pemahaman kepada peserta pelatihan Tes Kemampuan Akademik di Kota Samarinda.
