The large number of students wearing backpacks to school can be proven from the results of a survey conducted at SD N Bumisari, Natar District, South Lampung. Of the total number of subjects, 456 elementary school students carried 404 students (88.6%), and 52 students (11.4%) carried sling bags. But they rarely pay attention to the weight of the burden on the bag he carries everyday which turns out to cause injury to back pain.The tool is made in the form of a wearable device where the tool is in the form of a backpack that can be carried anywhere without having to require AC current as input voltage to the tool, because the power uses DC current with a voltage of 5V, the device is made using a microcontroller supported by a 10 kg loadcell sensor, modules HX711, keypad, plus an indicator component in the form of a buzzer. If the bag load exceeds the safe limit, the buzzer indicator will sound.","PeriodicalId":368769,"journal":{"name":"Jurnal Ilmiah Mahasiswa Kendali dan Listrik","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132765200","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}

Sistem yang dirancang terdiri dari beberapa bagian yaitu: catu daya, sistem kontrol, rangkaian mekanika dan program. Catu daya merupakan sumber daya untuk menjalankan seluruh sistem yang terdiri dari tegangan. Sistem kontrol berupa rangkaian elektronik yang didesain sedemikian rupa sehingga dapat berfungsi sebagai pengolah data dengan mikrokontroller sebagai pusat kendali. Bagian selanjutnya adalah rangkaian mekanika yang berfungsi untuk mengatur buka tutup pembuangan pakan pada alat pemberi pakan ikan. Bagian terakhir adalah program yang berfungsi untuk mengatur mikrokontroler sehingga dapat bekerja sesuai dengan fitur yang dikerjakan.","PeriodicalId":368769,"journal":{"name":"Jurnal Ilmiah Mahasiswa Kendali dan Listrik","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125846772","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}
