Periode penelitian dilakukan mulai 1 Januari 2022 – 31 Agustus 2022. Hasil eWOM menunjukkan topik yang paling sering dibicarakan pengguna Tiket.com di Instagram adalah seputar keluhan error dan sold out, permintaan membalas DM, dan Bali & Jogja sebagai tempat wisata menarik. Kemudian didapati sebagian besar persepsi pengguna Tiket.com dapat dikatakan baik karena persentase sentimen positif lebih unggul dibandingkan dengan persentase sentimen negatif. Selain itu, eWOM yang ada di jaringan Instagram bersifat lambat dan sulit tersebar karena konsumen jarang berinteraksi dengan sesama konsumen dan hanya fokus dengan komentarnya sendiri. Diketahui juga bahwa seorang influencer yang memiliki engagement rate yang baik juga komunitas yang telah dimiliki ditambah dengan persona yang sesuai dengan konsumen Tiket.com dapat menjadi penggerak eWOM di jaringan sosial Tiket.com dan hasil analisa eWOM menggunakan big data analitik dapat digunakan untuk rekomendasi program pemasaran Instagram Tiket.com Kata Kunci-eWOM, Instagram, sentiment analysis, social network analysis, topic modelling

Abstract

Corn is one of the staple foods utilized by humans as a food source and for other products; the planting, harvesting, and processing of corn significantly affect its quality. Generally, the problem faced by corn farmers is during the harvest season, where corn that is ready for harvest requires a very complicated process to obtain corn seeds. Generally, farmers perform the tasks of husking and shelling corn using their hands or makeshift tools. From this complex process, this research was conducted with the aim of designing a corn husker, corn sheller, and corn cob crusher machine. The process used in this machine is based on the principle of transfer using a screw conveyor that will move from the peeling process to the shelling process and finally to the corn cob crushing process. This research uses the method of manufacturing process analysis of several components that make up the machine and the calculation of the production cost of goods manufactured. From the results of the analysis of the research on the manufacture of the peeling machine, corn sheller, and corn cob crusher, the production cost of goods manufactured was obtained at Rp. 4,066,919, and the machine processing time was 11.4 hours
