Perubahan cuaca ini juga bergantung pada curah hujan. Pada perkebunan seperti perkebunan kelapa sawit cuaca mempengaruhi banyak aspek salah satunya adalah produktivitas buah kelapa sawit. Sehingga yang diperlukan dalam hal ini adalah peramalan. Peramalan merupakan suatu kegiatan untuk meramalkan apa yang terjadi di masa depan dengan metode tertentu. Metode fuzzy time series dikenal sebagai kecerdasan buatan yang digunakan untuk memprediksi masalah dimana data aktual dibentuk dalam nilai-nilai linguistik menggunakan prinsip fuzzy sebagai dasarnya. Penelitian ini membahas tentang metode fuzzy time series yang dikembangkan oleh Ruey Chyn Tsaur untuk memprediksi curah hujan di PPKS Bukit Sentang, Sumatera Utara. Perkiraan curah hujan berdasarkan data Januari 2017 sampai dengan Desember 2020 untuk prediksi tahun 2021. Peramalan ini memiliki nilai MAPE 0,37% atau memiliki presisi perkiraan 99,63%. Hasil penelitian ini menunjukkan bahwa metode Fuzzy Time Series Ruey Chyn Tsaur memiliki tingkat akurasi yang sangat baik untuk memprediksi curah hujan.","PeriodicalId":53096,"journal":{"name":"Jurnal Matematika Integratif","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44535308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 (011) (011) 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.","PeriodicalId":53096,"journal":{"name":"Jurnal Matematika Integratif","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45851897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The addition of new base (Dummy) causes a sequence of bases to become five nucleotide bases called ancient genetic codes. The five base set is denoted by , where B forms group through matching , , , , and from set . Ancient genetic codes can be reviewed as algebraic structures as a vector spaces and other structures as symmetry groups. In this article, discussed the properties of symmetry groups from ancient genetic codes that will produce dihedral groups. The study began by constructing an expanded nucleotide base isomorphism with . The presence of base causes to have a cardinality of 24, denoted as with . isomorphic with which is denoted by . Group had three clasess of partitions based on strong-weak, purin-pyrimidin types, and amino-keto nucleotide groups which are denoted as , , and . All three classes are subgroups of .
