The potential of solar energy certainly affects the power generated in solar modules, there are several influences that cause solar energy not to be obtained optimally. In this study will be made mathematical modeling using multiple regression methods exposed to the angle of tilt and intensity of the sun with the research object of the polycristalline type solar module. The results obtained by calculating mathematically obtained the accuracy of the model with MAPE, as well as the adjusted value of R square of 0.960363563 which states that the percentage of the influence of irradiation-free variables and temperature simultaneously on the current obtained is very strong. While the results of calculations with double linear regression, the value of the regression coefficient on the irradiation variable (x_1) by 0.0000316, it means that if other variables remain and irradiation variables increase by 100 W/m2, then the current increases by 0.00316 A. Then the regression coefficient on the temperature variable (x_2) by 0.010573, this means if other variables remain and temperature variables increase by 1oC, then the current increases by 0.010573 A. From these results, it should be known the level of accuracy of the model which in this case uses MAPE. MAPE obtained on this model is 7.046%, this corresponds to the error standard of 0.007650294 with an average current measurement scale of ±0.1 A. Thus, the MAPE results show that the model has an accuracy of 92.954%, which means that the modeling obtained is very good.","PeriodicalId":164637,"journal":{"name":"Jurnal Fokus Elektroda : Energi Listrik, Telekomunikasi, Komputer, Elektronika dan Kendali)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131672277","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}

PLN (Persero) as an lsitrik energy provider has the task of checking and measuring the use of electricity used by customers. In this case of course requires technology to be able to read how much electrical energy is used, one of the technologies used is Automatic Meter Reading (AMR). The use of Automatic Meter Reading (AMR) system includes monitoring, recording the stand meter then the data can be displayed in the form of a report with data software used management. Electronic meters using AMR systems can be used as a detection tool against irregularities from troubled customers. The readings obtained from AMR are known to the customer's usage, moments before the maintenance error and after. So that it can accurately detect customers who occur maintenance errors and customers and PLN both know the amount of uncollectible kWh, so far the nursing has been impaired by maintenance errors from the beginning of the tide. Based on existing data AMR should not be worth kWh value, but with the error of maintenance in phase S kWh measurable import that will be calculated to obtain a follow-up bill. The result obtained is true there is an inverted phase, it is shown in the fasor diagram where the angle of phase S which was originally 168.30 to 14.40. So that in the stand meter becomes minus the impact due to the mistake of maintenance obtained follow-up bill is 41538.8 kWh equivalent to Rp. 60.949.050,- after calculation.

Preprocessing digunakan untuk menyaring kata yang dianggap perlu untuk kebutuhan klasifikasi. Kesalahan penulisan pada tweet merupakan suatu permasalahan dalam tahap preprocessing yang tentunya mempengaruhi tingkat akurasi klasifikasi. Berdasarkan hal tersebut dibutuhkan proses tambahan pada preprocessing untuk melakukan koreksi kesalahan penulisan kata. Pada penelitian ini, penulis membandingkan kinerja metode levenshtein distance dan jaro-winkler distance dalam melakukan koreksi kesalahan penulisan kata. Penelitian ini diawali dengan melakukan survei literatur untuk mengidentifikasi masalah. Selanjutnya melakukan studi pustaka untuk menentukan objek dan parameter yang dibutuhkan dalam merancang dan memodelkan data serta perangkat lunak. Perangkat lunak dikembangkan menggunakan bahasa pemrograman python dengan beberapa library sastrawi, levenshtein, pyjarowinkler dan sklearn. Perangkat lunak ini dibangun untuk memudahkan dalam melihat kinerja metode yang digunakan. Pengujian dilakukan menggunakan confusion matrix dengan 10 fold cross validation. Pengujian melibatkan pengukuran kinerja levenshtein distance jika ditempatkan sebelum dan sesudah proses stemming. Begitupula untuk metode jaro-winkler distance juga ditempatkan sebelum dan sesudah proses stemming dalam preprocessing. Dari hasil pengujian diperoleh nilai accuracy, recall dan f1score dari metode levenshtein distance lebih baik dibandingkan jaro-winkler distance. Penerapan koreksi kata dengan metode levenshtein distance juga meningkatkan accuracy, recall dan f1score jika dibandingkan tanpa koreksi kata pada preprocessing.
