Karakteristik Isolasi Plastik Terhadap Tegangan Tinggi

Penelitian ini bertujuan untuk mengetahui karakteristik isolasi plastik terhadap tegangan tinggi AC, DC. Pada penelitian ini akan diuji mengenai karakteristik tegangan gagal dan kekuatan dielektrik dari material plastik dengan melakukan variasi pada jumlah lapisan plastik yang diuji. Penelitian ini dilatarbelakangi karena semakin meluasnya apilkasi plastik pada kehidupan, khususnya pada dibidang teknologi sistem isolasi oleh karena itu perlu dilakukan penelitian dan juga studi literatur untuk mengetahui jenis plastik yang memilki ketahanan yang terbaik terhadap listrik sehingga dapat dimanfaatkan sebagai materi isolasi tegangan tinggi. Sampel uji yang digunakan dolam pengujian ini adalah plastik jenis Polietilen, Polipropilen, Polivinil Klorid yang dipotong berbentuk segiempat dengan ukuran 7 x 7 em. Dengan ketebalan masing-masing sebesar 0.8 mm ,0.8 mm, dan 0.7 mm. Langkah pengujian ini adalah:Pengujian tegangan gagal pada tegangan AC,DC dan perhitungan kekuatan diel~ktrik pada tegangan AC, DC. Hasil penelitian menunjukkan bahwa pada tegangan tinggi AC Po/ietilen memiliki tegangan gagal yang paling tinggi dengan semakin bertambahnya jumlah lapisan,dimana pada jumlah lapisan sebesar 25 diperoleh nilai /egangan gagal sebesar 77.15 kV dan kekuatan dielektrik sebesar 96.44 kV/mm. Sedangkan pada pengujian tegangan tinggi DC Polipropilen memiliki tegangan gagal yang paling tinggi ,dimana pada jumlah lapisan sebesar 25 diperoleh nilai tegangan gagal sebesar 170.925 kV dan kekuatan dielektrik sebesar 213.66 kV/mm

Aplikasi Pemesanan Makanan Berbasis Mobile pada Rumah Makan “Lek Nonong”

The restaurant business that began growing in Semarang in particular areas Tembalang. Various types of food and drink offered by restaurants. Of course, to be able to compete the restaurant needs good management in the effort to obtain optimal benefits. Based on the problems need to develop an Order Food Mobile-Based Application to support the work processes of the restaurant, especially in the booking process and report transactions menu. The mobile application was built using jQuery Mobile programming language and HTML. The use of mobile applications is supported by an application which is running on a desktop computer that was built using the programming language PHP, Javascript and MySQL databases. Modeling applications was built using DFD (Data Flow Diagram). The results of the design Order Food Mobile-Based Application is an application that can be used for the work process and manage reports deals on restaurants, and also an application that can be used to enter the booking menu using mobile devices

Proceedings of the 3rd International Conference on Community Engagement and Education for Sustainable Development

This proceeding contains articles on the various ideas of the academic community presented at The 3rd International Conference on Community Engagement and Education for Sustainable Development (ICCEESD 2022) organized by the Universitas Gadjah Mada, Indonesia on 7th-8th December 2022.  ICCEESD is a biannual forum for sharing, benchmarking, and discussing HEI’s activities in developing Education for Sustainable Development towards community engagement. Education for Sustainability as a teaching strategy for resolving community challenges through formal, informal, or non-formal education is expected to benefit from various community service best practices by academics, researchers, and students. The 3rd ICCEESD has “Strengthening Education for Sustainability Towards Better Community Engagement” as its theme this year. It is expected that the 3rd ICCEESD will provide a forum for the presenters and participants to exchange best practices, policies, and conceptual implementation of Education for Sustainability towards better community engagement and explore ideas to address community needs.  Conference Title: 3rd International Conference on Community Engagement and Education for Sustainable DevelopmentConference Theme: Strengthening Education for Sustainability Towards Better Community EngagementConference Acronyms: ICCEESD 2022Conference Date: 7th-8th December 2022Conference Location: Grand Rohan Jogja Yogyakarta, IndonesiaConference Organizer: Universitas Gadjah Mada, Indonesi
