Abstract

Catfish is a cultivated fishery commodity that has quite large business opportunities to be developed to fulfill community nutrition. Feeding in catfish farming is very important and is one of the things that really needs to be considered. Feeding must be planned so that catfish can grow optimally. Unscheduled feeding results in increased cannibalism among catfish. The use of an automation system must be implemented in order to make it easier and more efficient in feeding catfish. The research method used in writing this scientific work is by using literature study. The purpose of this writing is to find out and implement an automation system for feeding catfish to make it easier and more efficient in feeding catfish. The results obtained from this automatic tool can make it easier for humans to operate, so that it no longer needs to be powered manually. Just automatically use the feeder. In conclusion, the implementation of an automatic system using IoT and Arduino Uno has been proven to be able to streamline catfish feeding times.

Abstract

Metode pengelasan SMAW digunakan secara luas dalam industri untuk menggabungkan material logam dengan kekuatan yang tinggi. Namun, pengelasan SMAW dapat menghasilkan cacat seperti porositas, retak, dan pengotoran yang dapat mempengaruhi kekuatan dan keandalan sambungan las. Penelitian ini bertujuan untuk menginvestigasi pengaruh ketebalan root face dan polaritas terhadap defect pada tembusan hasil pengelasan SMAW (Shielded Metal Arc Welding) dengan kuat arus ideal. Adapun Metode penelitian yang digunakan pada penelitian ini yaitu metode eksperimen dengan acuan uji AWS D1.1. Teknik pengumpulan datanya dengan melakukan pengujian pelat menggunakan cairan dye penetrant test dengan waktu yang dibutuhkan selama 40 menit setiap spesimen. Hasil penelitian menunjukkan bahwa ketebalan root face yang optimal dapat mengurangi terbentuknya defect pada tembusan pengelasan SMAW. Ketebalan root face yang terlalu tipis dapat menyebabkan pengotoran dan porositas, sedangkan ketebalan yang terlalu tebal dapat menyebabkan retak atau reject pada sambungan las. Selain itu, polaritas juga mempengaruhi terbentuknya defect. Penggunaan polaritas yang tepat dapat mengurangi terjadinya porositas dan retak pada sambungan las. Dapat disimpulkan bahwa dimana polaritas DCEN  menghasilkan tembusan yang ideal pada root face 2 mm, sedangkan Polaritas DCEP  menghasilkan tembusan yang ideal pada root face 3 mm, maka dari itu kami rekomendasikan polaritas DCEN sangat cocok untuk  pengerjaan root face 2 mm pada proses pengelasan SMAW.

Abstract

The 21st-century work environment presents new challenges for education. Therefore, preparing students to face the 21st-century work environment requires innovative and relevant educational approaches. This study aims to analyze the preparation of SMKN 7 Serang City students in facing the 21st-century work environment through a project-based learning (PjBL) approach. This research uses a descriptive quantitative approach, data in the form of questionnaires are analyzed to identify teamwork, project management, communication skills, interpersonal skills, and problem-solving. The results showed that PjBL has made a positive contribution to improving students' 21st-century skills. Students involved in PjBL have a deeper understanding of the application of theoretical concepts in the context of the work environment. The conclusion is that PjBL is an effective learning method in preparing students of SMKN 7 Serang City for the 21st-century work environment. The results of this study confirm the importance of innovative approaches in vocational education to ensure students have skills and knowledge relevant to future developments.
