Saat ini cukup banyak digunakan hal yang mudah dan simple untuk berbagai keperluan pekerjaan manusia. Dalam hal ini sistem kontrol sebagai suatu disiplin ilmu yang memungkinkan diterapkannya otomatisasi. Pada penelitian menggunakan sensor cahaya sebagai alat otomatis menghidupkan dan mematikan lampu . alat yang di gunakan pada penelitian ini adalah Sensor Cahaya LDR. Photoresistor digunakan sebagai alat utama pada penelitian ini. lalu Transistor NPN TIP120 adalah transistor yang sering di gunakan dan di maanfaatkan sebagai saklar otomatis yang menyambungkan mikrokontroler ke komponen yang memerlukan tegangan tinggi. Hasil akhir dari penelitian ini adalah sistem pencahayaan otomatis pada jalan komplek Pendidikan Yayasan Al-Ma’arif yang mengontrol lampu berdasarkan ada/tidaknya cahaya dari sensor di sekitar lampu, yang kemudian menjadi otomatis. Lampu akan menyala otomatis saat sensor tidak mendapat cahaya, begitu juga sebaliknya lampu akan mati otomatis saat sensor mendapatkan cahaya.
- Access to information in the current era is easily accessible and can be accessed anywhere and anytime. Our data can be accessed in public or confidential, for confidential data the very need for security is taken or manipulated by parties who are not responsible. One way to support data is by disguising data to codes that cannot be done using cryptography. In cryptography that contains many algorithms, this study combines the Hill cipher and Vernam Cipher methods that facilitate using the state administration code and Tax. The results of this study are the hill cipher conversion method with the state administration code and the regional abbreviation code in Indonesia, after which it is combined with the vernam cipher method which also combines with the tax value. The results of encryption with this algorithm combination type .txt file that contains a combination of letters, numbers, and symbols. Testing is done by comparing the process of several file types in terms of speed and the amount of data needed at the time of encryption and description.Keywords: Vernam Cipher, Hill Cipher, Kriptografi. Abstrak - Akses informasi pada era sekarang ini sangatlah mudah dan dapat diakses dimanapun dan kapanpun. Bahkan kita dapat mengakses data yang dipublish ataupun yang bersifat rahasia, untuk data yang bersifat rahasia sangat perlunya keamanan karena rentan diambil atau dimanipulasi oleh pihak - pihak yang tidak bertanggung jawab. Salah satu cara untuk mengamankan data dengan menyamarkan data ke kode - kode yang tidak bermakna yang dapat dilakukan menggunakan kriptografi. Dalam kriptografi terdapat banyak algoritma, pada penelitian ini mengkombinasikan metode Hill cipher dan Vernam Cipher yang dimodifikasi menggunakan kode administrasi negara dan Pajak. Hasil dari penelitian ini adalah memodifikasi metode hill cipher dengan kode administrasi negara dan kode singkatan daerah di Indonesia, setalah itu dikombinasikan dengan metode vernam cipher yang dimodifikasi juga dengan nilai pajak. Hasil dari enkripsi dengan kombinasi algoritma ini bertipe file .txt yang berisi kombinasi huruf, angka, dan symbol. Pengujian dilakukan dengan membandingkan proses beberapa jenis file dari segi kecepatan serta jumlah data yang diproses pada saat enkripsi dan deskripsi.Kata Kunci: Vernam Cipher, Hill Cipher, Kriptografi.
Abstract— In this modern era, the assessment of an individual with other individuals is still in the subjective stage, a human being assesses the abilities of other humans by using various points of view. Likewise, what Pratikan did to his Pratikum Assistants gave them an assessment that was in accordance with what they had, but the assessment sometimes had different parameters so that the conclusions between one person and another were different, there was no similarity in judging one person. With the Simple Additive Weighting (SAW) method, the problem can be solved with the help of this method. Websites that have become part of social life and are closely integrated in daily activities. So using the SAW method, one of the alternatives in the assessment can provide a Pratikum Assistant. The results obtained from these values can provide a new perspective on various kinds of problems. Deciding that no Practicum Assistant can be reused or the results of a given Assessor can help create a new resolution to the pattern of scoring in Practicum Assistants.
- The high number of diabetes patients in Indonesia is increasing. Some of the factors that cause diabetes in Indonesia include family history, obesity, aging, lack of activity and diet. Too much food containing sugar is also one of the emergences of diabetes. Most diabetics often have complications of diabetes disease and that is based on the criteria of a patient. Therefore, it is necessary to conduct research on the rule or dependence of the disease based on patient criteria and determination of diet for diabetics. In this study using a combination of a priori methods to determine the rule of disease and forward chaining to determine patient food. Based on the research tests conducted, it can be concluded that the combination of 2 methods produces a pretty good which in the a priori method uses a minimum value of support 2 and a minimum of confidence 10 and produces 10 rules with 3 combinations of items, as well as forward chaining tests that use 30 data produces an accuracy of 83 %.Keywords - Apriori Algorithm, Forward Chaining, Diabetes Abstrak - Tingginya jumlah pasien diabetes yang terjadi di Indonesia semakin meningkat. Beberapa faktor penyebab penyakit diabetes di Indonesia anatara lain riwayat keluarga, obesitas, pertambahan usia, kurangnya aktivitas dan pola makan. Terlalu banyak makan yang mengandung gula juga merupakan salah satu munculnya penyakit diabetes. Kebanyakan penderita diabetes sering sekali terjadinya kompliksi penyait diabetes dan itu berdasarkan kreteria seorang pasien. Maka dari itu perlu dilakukan penelitian mengenai rule atau keterhungungan penyakit berdasarkan kriteria pasien dan penentuan pola makan bagi penderita penyakit diabetes. Pada penelitian ini menggunakan kombinasi metode apriori untuk menetukan rule penyakit dan forward chainning untuk mentukan makanan pasien. Berdasarkan pada pengujian penelitian yang dilakukan dapat diambil kesimpulan Kombinasi 2 metode ini menghasilkan cukup bagus yang mana pada metode apriori menggunakan nilai minimal support 2 dan minimal confidence 10 dan menghasilkan 10 rule dengan 3 kombinasi item, serta pengujian forward chaining yang menggunakan 30 data menghasilkan akurasi 83% .Kata Kunci - Algoritma Apriori, Forward Chaining, Diabetes
In this increasingly advanced era, Information Technology (IT) is unavoidable. Everyone is competing to find innovations that can improve their performance. Private Universities (PTS) in Indonesia are no exception. An educational institution's attendance list is the primary reference in monitoring student activities. Although this sector is critical, traditional data collection is still taking place. As a result, many problems arise, such as data loss, long charging times, long queues, overcrowding, and even affects student concentration. ITS NU Kalimantan is one of several private universities in Central Kalimantan and is still relatively new. Student attendance applications are designed and developed for more mature data collection to avoid problems that arise later. This study offers the use of web android-based technology equipped with a QR code feature. Based on the questionnaire results conducted on 45 respondents who used the UAT model, the perceived usefulness aspect was 82%, the perceived ease of use aspect was 84%, the perceived user acceptance aspect was 82%, and the average rating produced was 83%. This percentage shows that users respond positively to this attendance system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
