Judul: Pengembangan Frontend pada Aplikasi Pelelangan Ikan Terintegrasi berbasis Progressive Web  App
Abstrak: Data perikanan rutin dikumpulkan melalui Tempat Pelelangan Ikan (TPI) untuk membantu pemerintah melakukan perencanaan dan evaluasi pengembangan produksi perikanan. Namun, pengumpulan data di TPI masih dilakukan secara konvensional. Hal tersebut menyebabkan proses pengumpulan data menjadi tidak efisien. Penelitian ini membahas pengembangan Aplikasi Pelelangan Ikan Terintegrasi bagian frontend untuk membantu pengelolaan data aktivitas di TPI. Sistem dibuat menggunakan metode scrum dan berbasis progressive web app untuk mendukung fleksibilitas penggunaannya di berbagai platform. Tampilan yang berhasil dibuat dalam penelitian ini adalah tampilan untuk mencatat tangkapan ikan, mencatat hasil lelang ikan, mencatat transaksi pembelian, rekap data, laporan, dan dashboard. Data tangkapan ikan dan hasil lelang akan dicatat oleh petugas TPI, sedangkan data transaksi akan dicatat oleh kasir. Data tersebut kemudian akan diproses menjadi laporan produksi ikan dan laporan transaksi lelang yang dapat diakses oleh Admin TPI dan Dinas perikanan. Sistem diharapkan dapat mempermudah Petugas TPI mengumpulkan data aktivitas TPI dan membantu pemerintah untuk mengambil keputusan., Fishery data is collected through the Fish Auction Place (TPI) to assist the government in planning and evaluating the development of fisheries production. However, data collection at the fish auction is still done manually. This causes an ineffective data collection process. This study discusses process the Integrated Fish Auction Application development from the frontend side to manage activity data at TPI. The system was developed using the scrum method and made based on a progressive web app to support the flexibility of its use on various platforms. The interface that was successfully created in this study is a page view to record fish catches, record auctions, record transactions, recap data, reports, and dashboard. The data on fish catches and auction results will be recorded by TPI officers, while transaction data will be recorded by the cashier. All the data then will be processed into fish production reports and auction transaction reports which can be accessed by the TPI admin and the fisheries office. The system is expected to make it easier for fish auction officers to collect data and assist the government in making decisions.

Judul: REST API Based Backend Development on Integrated Fish Auction Application
Abstrak: Application Programming Interface (API) adalah sebuah abstraksi yang dibuat oleh pengembang sehingga fungsi-fungsi di dalam sistem dapat diakses melalui program komputer. Representational State Transfer (REST) adalah arsitektur pengembangan API yang menggunakan Hypertext Transfer Protocol (HTTP) untuk pertukaran data. Penelitian ini mengimplementasikan REST dalam mengembangkan API sebagai back-end dari Aplikasi Pelelangan Ikan Terintegrasi. API yang dikembangkan menggunakanan Javascript Object Notation (JSON) sebagai format standar dari komunikasi data dan JSON Web Token (JWT) sebagai autentikasi. Penelitian ini menunjukkan pengembangan API berhasil dilakukan menggunakan metode scrum yang terdiri dari 4 sprint dan 17 product backlog untuk fitur autentikasi, pencatatan serta rekap hasil tangkapan, hasil lelang, dan transaksi serta fitur laporan dan dashboard., Application Programming Interface (API) is an abstraction built by developer so functions of the system can programmatically be accessed. Representational State Transfer (Rest) is an API development architectural style that uses Hypertext Transfer Protocol (HTTP) for data communication. This research implemented REST in developing API as the back-end of Integrated Fish Auction Application. API was developed using Javascript Object Notation (JSON) as standard format for data communication and JSON Web Token (JWT) as authentication. This research indicates that the development of API successfully performed using scrum method that consists of 4 sprints and 17 product backlogs for authentication, record and recap for fish caught, auction, and transaction data and also reporting and dashboard feature

Judul: Pelabelan Super Vertex Magic
Abstrak: Super vertex magic labeling is labeling on graph with is a set of edges mapped into and is a set of vertices mapped into . It has a vertex magic labeling in which and represents the size and order of the graph respectively. This manuscript proves that paths, cyclics, and disjoint union of cyclics have a super vertex magic labeling. There are four theorems to be discussed. The first theorem proves that path is super vertex magic if and only if is odd and . The second theorem proves that cyclic is super vertex magic if and only if is odd. The third theorem proves that bijection function from an edge set onto of graph can be extended to a super vertex magic labeling if and only if the set amount of edge label that incidents with a vertex in the graph, consists of sequential integers as many as vertices in the graph. The fourth theorem proves that disjoint union of the cyclics consists of cyclics with each cyclic has vertices is super vertex magic if and only if and are odd.
