Abstract

Kekeringan adalah salah satu bencana alam yang terjadi secara perlahan berlangsung lama hingga musim hujan tiba yang mempunyai dampak yang luas. Salah satu dampak kekeringan pada bidang pertanian pernah terjadi pada kabupaten Indragiri Hulu pada tahun 2015. Daerah irigasi (D.I) Kelayang merupakan daerah irigasi potensial yang mengairi wilayah pertanian di Kabupaten Indragiri Hulu. Untuk menanggulangi dampak kekeringan untuk masa yang akan datang perlu dilakukan peramalan indeks kekeringan. Indeks kekeringan sangat bergantung pada curah hujan. Untuk itu dilakukan peramalan curah hujan D.I Kelayang menggunakan metode Seasonal Autogressive Integrated Moving Average (SARIMA) karena diduga curah hujan merupakan data yang mengandung pola musiman. Kemudian dilakukan analisis indeks kekeringan menggunakan metode Standardized Precipitation Index (SPI). Hasil penelitian diperoleh model SARIMA (2,0,1)(0,1,1)12 merupakan model yang layak digunakan untuk peramalan karena telah melewati uji kerandoman dan kenormalan residual dengan mean squared dari residual yang terkecil yakni 4111,51. Setelah data peramalan curah hujan tahun 2019 didapatkan, dilakukan analisa indeks kekeringan dan diperoleh indeks SPI bernilai negatif yang tertinggi terjadi pada bulan Januari yaitu -0,252, sedangkan SPI bernilai positif tertinggi terjadi pada bulan Juli yaitu sebesar 0,169. Indeks kekeringan di D.I Kelayang bersifat “Normal”. Peramalan indeks kekeringan ini dapat menjadi informasi tambahan bagi Badan Nasional Penanggulangan Bencana.

Abstract

This research was motivated by the anxiety of students of mathematics education study program towards HOTS mathematics problems. This anxiety affected the quality of their thought processes. Therefore, the purpose of this study was to analyze the thought processes of students with anxiety feeling about HOTS math problems based on Mason's work phases, namely entry, attack, and review. This research was a qualitative descriptive research. The datas in this study were obtained from mathematics anxiety questionnaire, HOTS mathematics test and interviews. Based on the analysis of the data collected, it could be concluded that students with high levels of anxiety fulfill the phase “entry“ only on aspect “want”, the phase “attack” was only in the aspect ”try”, but did not meet the phase “review”. Students with moderate levels of anxiety met the phase “entry” at aspect “know”, “want” and “introduce”, phase “attack” on the aspect “try” and “maybe”, but did not meet the phase “review”. Students with low anxiety levels met the phase “entry” at aspect “know”, “want” and “introduce”, the phase “attack” on the aspects “try”, “maybe” and “introduce”, but also does not meet the phase “review”.

Abstract

Farmers are concerned about the problem of drought in agriculture because it will disrupt the production system and cause losses. In 2015, the Indragiri Hulu area experienced a drought on 273 hectares of agricultural land. This area is part of the Indragiri River Watershed in Riau Province. To prevent the impact of future droughts, forecasting is required. The level of drought is influenced by rainfall, so the Seasonal Auto Regressive Integrated Moving Average (SARIMA) method is used to model rainfall data. In addition, the Standardized Precipitation Index (SPI) is also used to analyze the drought index. After the analysis, it was found that the best model in forecasting is SARIMA model (1,0,1)(2,1,1)12 with an average residual square of 18.0175, and the drought index in the Indragiri watershed is currently included in the  "Normal" category. The results of this forecasting are expected to assist the Riau Province National Disaster Management Agency in anticipating and mitigating the impact of future drought disasters.

Abstract

Padang city has been in the red zone (high risk) and orange zone (medium risk) against the transmission of the Covid-19 virus for several months. This is due to the lack of community discipline in complying with health protocols. The existence of the Andalas University Hospital Laboratory in Padang City which has the tools to issue the SWAB test results also results in data being obtained very quickly and data collection is more accurate. To predict the number of new cases of Covid-19 patients, research on forecasting is necessary. One method that can be used is the Seasonal Autoregressive Integrated Moving Average method or abbreviated as SARIMA. This method was chosen because the data shows a weekly seasonal pattern. The data used are daily data from 2 August 2020 to 6 January 2021 obtained from the Padang City Health Office . The results showed that the SARIMA (0,1,1) (0,1,1) 7 model is the best model with parameter estimates that are significantly different from zero, so that it fulfills the white noise assumption with a Means Squared Error value of 3.46731. Forecasting results for the next month show that cases of Covid-19 patients are still fluctuating, ranging from 20 to 66 people. For this reason, efforts from the local government of the City of Padang are needed in disciplining the community so that the conditions of Padang City can immediately turn into a green (safe) zone from Covid-19.
