Petir dapat merusak komponen yang ada pada menara transmisi, yang membuat sistem tramsmisi daya listrik menjadi terganggu. Menara transmisi yang berada di daerah perbukitan yang tinggi membuat menara transmisi menjadi sasaran utama petir untuk menyalurkan kelebihan muatannya akibat gesekan elektron di awan. Khusunya saluran transmisi 150 kV Payakumbuh-Koto Panjang di Sumatra Barat yang memiliki gangguan petir sebesar 66% Menurut data Pusat Pengendalian Distribusi dan Beban Sumatra (P3B Sumatra). Salah satu komponen yang digunakan untuk mengurangi kerusakan isolator akibat sambaran petir adalah arcing horn. Namun itu tidak cukup, maka dari itu perlu adanya gabungan komponen arcing horn dengan arrester. Dengan menggabungkan dua komponen tersebut tegangan lebih yang diakibatkan oleh sambaran petir bisa dipotong oleh arrester. Penambahan arrester pada sisi isolator mempunyai pengaruh yang sangat besar terhadap tegangan surja, dengan menambahkan 2 arrester pada sisi isolator tegangan yang mampu di potong oleh arrester adalah 88,3% dari tegangan surja yang diberikan dan jika menggunakan 1 arrester tegangan yang terpotong adalah 79,1% dari tegangan petir yang di berikan berdasarkan simulasi EMTP.","PeriodicalId":103642,"journal":{"name":"Prosiding Sains Nasional dan Teknologi","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117240553","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}

Dengan perkembangan sistem operasi Android saat ini, media penyampaian pesan lewat text juga ikut berkembang pesat dengan munculnya berbagai aplikasi pengiriman pesan, seperti WhatsApp, Telegram ataupun Line. Namun, meski aplikasi pengirim teks mulai bermunculan, layanan pesan singkat (SMS) masih bisa eksis digunakan untuk melakukan pertukaran informasi sampai sekarang. Karena keamanan privasi dalam suatu pertukaran informasi itu sangat penting, maka melakukan enkripsi pada pesan dapat menjadi alternatif untuk meningkatkan keamanan privasi pada pesan yang dikirim. Dari berbagai teknik enkripsi yang ada, penggabungan 2 teknik enkripsi merupakan langkah yang baik untuk lebih memingkatkan keamanan pesan, diantaranya adalah Vigenere dan Autokey. Dengan melakukan penggabungan teknik enkripsi dan pemanfaatan kunci unik diharapkan dapat meningkatkan keamanan dalam melakukan pertukaran informasi melalui SMS.","PeriodicalId":103642,"journal":{"name":"Prosiding Sains Nasional dan Teknologi","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128722772","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}
