Abstract

Kondisi job yang ditemukan pada perusahaan manufaktur pada umumnya lebih menyerupai kondisi yang terjadi pada kasus penjadwalan dynamic job shop dibandingkan dengan kasus penjadwalan static job shop. Pada kasus penjadwalan dynamic job shop, penjadwalan ulang perlu dilaksanakan pada kondisi waktu yang tidak pasti (random) sementara mesin tetap terus bekerja menyelesaikan job yang sudah masuk dan sedang diproses saat itu. Kasus penjadwalan ulang ini dapat disebabkan oleh beberapa sebab diantaranya dikarenakan job baru yang datang dan terjadinya gangguan yang menyebabkan berhentinya proses produksi pada mesin tertentu. Pada paper ini, kondisi dynamic job shop yang akan dipertimbangkan adalah kondisi dimana job baru yang terus datang secara kontinyu dalam interval waktu tertentu. Untuk lebih memodelkan kondisi nyata yang terjadi di lapangan, kami mempertimbangkan kondisi yang memungkinkan waktu proses pengerjaan operation dari sebuah job di mesin terjadi dalam waktu proses yang uncertain. Waktu proses yang uncertain dalam hal ini adalah kondisi dimana waktu proses pengerjaan tidak dapat dipastikan untuk dapat selesai dalam durasi waktu yang pasti. Fuzzy number akan digunakan untuk merepresentasikan kondisi waktu proses yang uncertain ini. Algoritma penjadwalan yang akan diimplementasikan pada paper ini adalah algoritma metaheuristic yang biasa digunakan pada kasus dynamic job shop yaitu variable neighborhood search. Kombinasi antara algoritma variable neighborhood search dan fuzzy number diharapkan dapat semakin meminimasi flowtime rata-rata dari keseluruhan job yang datang. Untuk memverifikasi dan membandingkan hasil flowtime rata-rata setelah fuzzy number diterapkan pada algoritma variable neighborhood search, fitur simulasi sederhana dapat dijalankan pada aplikasi yang dibuat dengan menggunakan bahasa pemrograman java.

Abstract

Kondisi job yang ditemukan di lapangan pada umumnya lebih menyerupai kondisi yang terjadi pada kasus penjadwalan dynamic job shop dibandingkan dengan static job shop. Pada paper ini, penulis mencoba merancang sebuah software aplikasi untuk membandingkan performansi algoritma penjadwalan dengan mempertimbangkan kondisi job yang dinamis dan uncertain berdasarkan data event log. Data event log digunakan untuk menghasilkan process model yang dapat merepresentasikan kondisi real proses menggunakan teknik process mining. Untuk lebih memodelkan kondisi nyata yang terjadi di lapangan, penulis membuat agar waktu proses pengerjaan operation dapat terjadi dengan waktu yang uncertain. Waktu proses yang uncertain adalah kondisi dimana waktu proses pengerjaan tidak dapat dipastikan untuk selesai dalam durasi waktu tertentu. Untuk memverifikasi dan membandingkan performansi algoritma penjadwalan, kami akan mengkombinasikan hasil process model, distribusi waktu operation, dan kondisi resource berdasarkan dari data event log dengan mekanisme simulasi. Indikator performansi yang dapat dibandingkan dan dianalisa meliputi throughput, flow time, waiting time, dan makespan. Colored Petri Net dan Gantt Chart akan digunakan untuk merepresentasikan dalam bentuk visual simulasi yang sedang berjalan secara real time sehingga lebih memudahkan dalam menganalisis angka indikator performansi. Aplikasi ini dirancang untuk dijalankan online agar siapa saja dapat mengunggah dan membandingkan algoritma penjadwaannya dengan algoritma lain yang sudah pernah diunggah sebelumnya pada kasus event log tertentu.

Abstract

The importance of the role of members of the Regional People's Representative Council (DPRD) as representatives of the community requires active involvement in absorbing, accommodating, collecting, and following up on community aspirations and complaints. However, the complaint process often faces obstacles that result in delays in resolving problems, ranging from the complexity of the complaint flow to the difficulty of finding an effective complaint platform. To overcome these challenges, an innovative step was taken, which was to create a website that provides a complaint feature via WhatsApp. The main objective of this initiative is to provide easier access to the community to participate in raising their complaints and complaints. With the WhatsApp complaint platform, it is hoped that the community can quickly and efficiently report problems and provide feedback to the local government. The WhatsApp complaint feature is integrated to minimize technical barriers and facilitate use by the wider community. Through this website, people can easily file complaints, send messages, and provide documentation related to the problems faced. With the implementation of this platform, it is expected that problem-solving can be done more efficiently and responsively. Thus, creating a public complaint website with a complaint feature via WhatsApp is not only a practical solution in dealing with the obstacles of the complaint process but also a significant step in encouraging active public participation in building a transparent and accountable government.
