Prototype Pengisi Air dan Penutup Botol Otomatis Berbasis Programmable Logic Controller

Pendidikan vokasi di Indonesia dituntut menghasilkan lulusan yang siap bekerja di pemerintahan maupun Industri. Oleh karena itu pendidikan Vokasi lebih banyak menekankan pembelajaran praktikum. Seperti Politeknik Aceh dengan pembelajaran praktikum 60 % dan teori 40 %. Modul praktik yang bervariasi sangat diperlukan untuk mendukung pembelajaran praktik di Politeknik Aceh. Salah satunya Modul Praktikum mata kuliah Programmable Logic Controller (PLC). Untuk menambah variasi modul praktikum PLC, maka dari itu penulis merancang modul praktikum yang menarik agar mahasiswa lebih memahami materi . Modul praktik yang dirancang adalah Prototype Pengisi dan Penutup Botol Otomatis yang bekerja seperti proses di Industri. PLC yang digunakan dari Schneider Elektric tipe Twido dengan seri TWDLCAE40DRF. Alat ini dilengkapi sensor Infrared Proximity sebagai pendeteksi botol, motor konveyor untuk membawa botol minuman, motor DC untuk mengisi air serta solenoid untuk penutupan botol. Mekanik alat ini menggunakan besi Hollow berukuran 3 mm x 3 mm dan menggunakan Aluminium Profile pada bagian atas rangka. Hasil yang diperoleh alat ini dapat bekerja dengan baik sehingga dapat digunakan sebagai modul praktikum, mampu mengisi air dalam waktu 14 detik dan mampu menutup tutup botol ukuran 250ml dengan diameter 3cm. Walaupun masih kurang mampu menutup botol dengan kuat, alat ini sudah layak dijadikan sebagai modul praktikum PLC.

Implementasi Kriptografi Pengamanan Data Pribadi Siswa SMA Swasta Jaya Krama Beringin Dengan Algoritma RC4

The personal data of the Jaya Krama Beringin Private High School students is required in the administrative data collection by the school. Personal data includes student identification such as student name, family identification number (NIK), gender, address, mobile number, e-mail, and so on. In today's digital era data is everything, with the development of the internet network that is increasingly easy to access, it is necessary to know and be aware of what things are personal data and what should be done to protect personal data. The research problem is that the personal data security of Jaya Krama Beringin High School students needs attention due to the widespread occurrence of data theft by hackers to be misused, it is necessary to need computer software for data security. The first step in the RC4 algorithm stage is to carry out the KSA (Key Scheduling Algorithm) process which at this stage is the process of forming an S-Box (Array S) with a length of 256 bytes (index 0 to 255) based on the encryption key. After using the XOR operation on the ciphertext with the key, the XOR result of the binary number obtained is converted into plaintext.

Sistem Pakar Mendiagnosa Penyakit Ayam Kampung Dengan Menggunakan Metode Certainty Factor Berbasis Web

Poultry farming in Indonesia is still not successful in meeting some of the domestic needs, including being vulnerable to attacks by dangerous animal diseases. People are also restless because of dangerous diseases from chickens that can be transmitted to humans due to consuming chicken meat that has been infected with the disease. The case study in conducting research to diagnose free-range chicken disease was carried out at the Bang Ari Chicken Farm on Jalan Jamin Ginting Pamen Complex No.14 Padang Bulan, Medan Baru District, Medan City. The required criteria data is the type of disease and symptoms of the disease that attacks native chickens as well as the treatment actions that will be taken against the diseased chickens according to the disease experienced. This study aims to build a web-based expert system in diagnosing free-range chicken diseases using the certainty factor method. From the case example, the results of the calculation of certainty factor on the symptoms of free-range chickens, the disease that has the largest percentage value is P 7, namely Chronic Cough Disease of 97.50%. The system for diagnosing free-range chicken disease was built using a web-based programming language and MySQL database.

Sistem Informasi Pengambilan Keputusan Penerima Rehab Rumah Menggunakan Metode Weighted Sum Model (WSM) Pada Desa Bira Lhok Kecamatan Montasik

The house renovation program provided by the Aceh Besar regional government, especially in Gampong Bira Lhok, Montasik District, is an assistance program for the welfare of villagers whose housing conditions are far from livable. The problem faced by the Gampong government in the decision system for recipients of house renovation assistance at this time is that it still uses the decision system of deliberations between the Gampong apparatus and the Village Head so that it takes time to make decisions. Therefore, it is necessary to have a Decision Support System (SPK) to determine the acceptance of the house rehab program for residents with livable housing conditions based on computer information systems. This final project research aims to build a decision-making information system for home rehabilitation recipients using the Weighted Sum Model (WSM) method in Bira Lhok Village, Montasik District. The system development method used is the SDLC (Software Development Life Cycle) method using PHP and MySQL programming. The final project research resulted in a decision making information system for home rehabilitation recipients using the web-based Weighted Sum Model (WSM) with a factor weighting form interface, a form for prospective beneficiaries, a form for income criteria, assets, food and buildings, as well as a report on the assessment list of prospective recipients of rehabilitation assistance. House. Based on the results of the system that was built, the presence of an information system for decision making for home rehabilitation recipients using the Weighted Sum Model (WSM) method has made it easier for the Gampong Bira Lhok government to make decisions for recipients of home rehabilitation assistance quickly.

Sistem Pendukung Keputusan Pemilihan Kain Terbaik Di Toko Crown Textile & Tailor Dengan Metode Simple Additive Weighting (SAW)

The retail business continues to grow rapidly along with the development of science and technology in the era of globalization, but the purchase of fabric is still done manually and not computerized, such as in choosing fabrics, only looking at the shape of the color and the price tag, if it is suitable and likes it is taken immediately without thinking what type of fabric to use. used for these clothes, when they have been made into clothes or clothes, do not match the criteria desired by consumers and many ready-made clothes are returned because the color becomes dull or faded, and does not match the desired motif. The problem in this study is to determine the selection of the best fabric using SPK with the Simple Additive Weighting (SAW) method in selecting the best fabric at Crown Textile Tailor built using PHP MyAdamin programming. The decision support system method used is Simple Additive Weighting (SAW), because it can determine the weight value for each attribute, through a ranking process selecting the best alternative from a number of alternative data, the results obtained are Viscose Rayon Fabrics worth 0.933, (Rank 1), Brukat Lace Fabrics are worth 0 .9 (Rank 2), Toyobo Cotton Fabric is worth 0.716 (Rank 3), Japanese Cotton Fabric is worth 0.700 (Rank 4).

Android Based Tire Patch Search

The number of motorized vehicles continues to increase, this will be directly proportional to the number of people who experience motorcycle damage when driving on the highway, such as leaking tires or burst tires. For motorists who do not know the surrounding area when a motorcycle tire is damaged, of course it will be difficult to find the nearest tire patch. In this study, an Android application will be developed to map and find the location of motorcycle tire patches in Bukit Raya District. This application will provide location-based services to users. With this application, users will get information in the form of a map showing the location of the nearest tire patch. Based on the test results, the tire patch location mapping application that was built is able to display the locations of the tire patches along with information on the travel route from the user's location to the nearest selected tire patch location. This application was developed on the Android operating system because Android provides an open platform for developers to create their own applications and Android is one of the operating systems that are widely used by smartphones that are growing rapidly now. This application is expected to help users who want to find the location of the tire patch along with information from the tire patch and the closest route to the tire patch location so that it is more efficient in terms of time
