The research article discussed the utilization of organic waste that always increases every year in line with the rate of population growth, therefore the article was prepared to review the utilization of organic waste as a form of conservation of electrical energy. The method in the research used is in the form of literature studies by collecting data from various sources or references relevant to the research conducted. The results of the literature study from several studies show that efforts to use organic waste derived from household waste, landfill waste, and organic waste in the market have the ability to be used for electrical energy sources and can be done energy conservation. The conclusion is that organic waste as an alternative to fossil fuels can be used as electrical energy, and that it can be used for energy conservation.

Solar energy is often known by other terms solar energy is a form of renewable energy source. 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.

PT. 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.

PT.

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.

Video transmission is encoded by block-based techniques such as MPEG in sensitive environment. It’s very susceptible to noise which can cause block losses and even missing frames during transmission. A technique to overcome this problem is applied Error concealment (EC) on the decoder. There are two approaches used in this EC, spacial EC which utilizes information around the image and temporal EC by utilizing motion information. The method of EC that used in this research is Frequency Selective Extrapolation (FSE). The video is encoded by the H.264 / AVC standard (MPEG-Part10). The isolated block losses was added to the video as an error simulation, then applied the EC-FSE method on the decoder. There are two method of EC-FSE used, FSE-2D (two dimensions) and FSE-3D (three dimensions). The measurement results were observed by the PSNR and MOS values. The simulation results show that H.264 / AVC video concealed with FSE-3D has a better performance than FSE-2D.

Mobil adalah kendaraan beroda 4 yang selalu dibutuhkan manusia untuk aktifitas bepergian atau keluar rumah. Sistem paling vital dari mobil salah satunya adalah pengereman. Sering kali mobil mengalami kecelakaan dari sector pengereman. Mobil membutuhkan jarak aman untuk pengereman yang ideal. Penelitian tentang Simulasi Pengereman Otomatis Menggunakan Sensor Ultrasonic Berbasis Arduino Uno menarik untuk dilakukan. Tujuan studi ini adalah untuk mensimulasikan pengeraman otomatis pada mobil. Roda mobil dimisalkan menggunakan motor DC. Komponen yang digunakan adalah motor DC, Sensor Ultrasonic, Arduino Uno, Buzzer / speaker, LCD. Semua komponen dikendalikan oleh Arduino Uno. Hasil yang didapatkan terdapat 3 kondisi yaitu Aman, Sedang, dan Berhenti. Kondisi tersebut ditampilkan melalui LCD. Jika saat kondisi Sedang maka motor DC akan mengurangi kecepatannya dan speaker akan menyala se-bagai peringatan. Jika kondisi Berhenti maka motor DC akan berhenti dan speaker juga menyala sebagai peringatan.

Jika kondisi Berhenti maka motor DC akan berhenti dan speaker juga menyala sebagai peringatan.","PeriodicalId":164637,"journal":{"name":"Jurnal Fokus Elektroda : Energi Listrik, Telekomunikasi, Komputer, Elektronika dan Kendali)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130510898","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}
Abstract — The research discusses the design of an automatic shoe rack with IoT-based cooling and elevator features. This shelf is made to handle messy shoes because people feel lazy and don't have time to just put their shoes on the shelf by hand and bend over. In addition, this automatic shoe rack aims to overcome dusty, smelly and moldy shoes due to open shoe racks and not getting enough wind. The Blynk app is used to operate an automated shoe rack IoT system. Abstrak — Penelitian membahas perancangan rak sepatu otomatis dengan fitur pendingin dan elevator berbasis IoT. Rak ini dibuat untuk mengatasi sepatu yang berantakan dikarenakan orang merasa malas dan tidak memiliki waktu untuk sekedar meletakkan sepatu ke rak menggunakan tangan serta membungkukkan badan. Selain itu, untuk mengatasi sepatu yang berdebu, berbau dan berjamur karena rak sepatu yang terbuka dan tidak mendapat cukup angin. Aplikasi Blynk digunakan untuk mengoperasikan sistem IoT rak sepatu otomatis.
