In the supply chain of foodstuffs derived from livestock, data consistency and security are the most important thing to pay attention to. However, the length of the existing supply chain and the lack of facilities to store and maintain the correctness of livestock data are problems in ensuring the security of the data. The use of blockchain in livestock has existed in Indonesia, but its scope is only to agriculture or only a small part of the livestock supply chain. Therefore, this research was conducted to develop the application of a blockchain-based livestock supply chain system in Indonesia. This research begins with conducting a literature study, analyzing the slaughterhouses. Then the development of a blockchain system for the food supply chain was carried out. System validation was carried out through interviews with the head of the slaughterhouses, breeders, and wholesalers. The results state that the system helps in ensuring the security of food supply chain data from livestock. However, the problem that has not been resolved is the validation process of data on the weight loss of foodstuffs in the course of the supply chain process. In the future, this technique is expected to be used for halal certification.
Industri komersial saat ini menerapkan teknik Customer Relationship Management (CRM) untuk mendapat berbagai keuntungan seperti menyediakan informasi pada pelanggan, meningkatkan loyalitas dan kepercayaan pelanggan, serta mempelajari perilaku pelanggan. Pendidikan dapat dipandang sebagai industri bidang jasa. Pada model tersebut, peran siswa dapat dipadankan dengan konsumen. Karenanya, ada peluang untuk menerapkan CRM dalam dunia pendidikan. Oleh karena itu, penelitian dilakukan untuk mengembangkan aplikasi student relationship management untuk Universitas Surabaya yang mencakup rekomendasi beasiswa dan acara, pengingat event, dan perekrutan panitia. Aplikasi yang dikembangkan menggunakan platform web dan pembuatan rekomendasi dilakukan dengan algoritma machine learning yaitu random forest, deep learning, dan stacked ensemble. Berdasarkan hasil uji coba dan validasi, aplikasi tersebut dapat membantu mahasiswa mengetahui informasi seperti beasiswa yang dapat diperoleh dan kegiatan yang dapat diikuti. Dengan demikian, ketika kepuasan mahasiswa terhadap layanan yang diberikan oleh universitas meningkat, maka hubungan baik antara penyedia jasa, dalam hal ini universitas, dan konsumennya, dalam hal ini mahasiswa, dapat dijaga.
