Judul: Back-end Modules Development with Low/No-Code Approach Jojonomic Officeless Operating System
Abstrak: Berkembangnya teknologi informasi dan tren digital mengakibatkan perusahaan/organisasi mengalami kesulitan dalam menghadapi permintaan yang kompleks dan cepat berubah. Low/No-Code platform hadir sebagai solusi pengembangan perangkat lunak yang lebih cepat dan efisien dibanding dengan yang menggunakan proses coding secara manual. Low/No-Code platform dapat membantu mempercepat proses pengembangan dan penyediaan aplikasi sebanyak 5 sampai dengan 10 kali lebih cepat serta mempermudah pemeliharaan. Officeless Operating system (OOS) merupakan contoh Low/No-Code platform di Indonesia sehingga pengguna dapat membangun aplikasi tanpa harus melakukan codingsecara manual. Tujuan penelitian ini adalah menerapkan Low/No-Code platform OOS untuk mendukung pengembangan modul back-end dalam studi kasus Sistem Inovasi Desa Digital yang berbasis mobile web. Penelitian ini dikerjakan menggunakan metode Iterative Waterfall. Hasil yang didapatkan berupa 14 endpoint API yang berhasil melewati pengujian dengan metode blackbox., Information technology advancement and digital trends have led companies/organizations to need help with complex and rapidly changing demands. The Low/No-Code platform emerges as a solution for faster and more efficient software development than manual coding processes. This platform can accelerate the development and deployment of applications by 5 to 10 times faster and simplify maintenance. The Officeless Operating System (OOS) is an example of a Low/No Code platform in Indonesia, enabling users to build applications without manual coding. This research aims to implement the OOS Low/No-Code platform to support the development of back-end modules in the Mobile Web-Based Digital Village Innovation System case study. This research uses the Iterative Waterfall method. The results include 14 API endpoints that successfully passed blackbox testing.

Judul: Pengembangan Modul Back-end Aplikasi Koper Pustaka Menggunakan Metode Waterfall
Abstrak: Koper Pustaka merupakan aplikasi yang dikembangkan dengan tujuan untuk mempermudah proses peminjaman paket buku milik pustakawan dan melacak keberadaan setiap paket buku yang dipinjam pemustaka. Rancangan mobile user experience Koper Pustaka telah dikembangkan sebelumnya. Berdasarkan rancangan tersebut, penelitian ini berfokus mengimplementasikan bagian back-end Koper Pustaka dengan gaya arsitektur Representational State Transfer Application Programming Interface (REST API) dan pola desain model-view-controller. Tujuan dari penelitian ini adalah mengembangkan bagian back-end yang mampu menghubungkan interaksi antara bagian front-end dari Koper Pustaka dengan database Koper Pustaka. Penelitian ini dikerjakan dengan menggunakan metode pengembangan perangkat lunak waterfall. Hasil dari penelitian ini adalah 43 endpoint API yang telah diuji dengan pengujian black-box. Selanjutnya, endpoint API tersebut dapat dipakai bagian front-end Koper Pustaka untuk berinteraksi dengan database Koper Pustaka., Koper Pustaka is an application that was developed with the aim of simplifying the process of borrowing book packages belonging to librarians and tracking the whereabouts of each package of books borrowed by users. Koper Pustaka's mobile user experience design has been previously developed. Based on this design, this research focuses on implementing the Koper Pustaka back-end with the Representational State Transfer Application Programming Interface (REST API) architectural style and the model-view-controller design pattern. The purpose of this research is to develop a back-end that is able to connect the interaction between the front-end of Koper Pustaka and the Koper Pustaka database. This research was carried out using the waterfall software development method. The results of this study are 43 API endpoints that have been tested by black-box testing. Furthermore, the API endpoint can be used by the Koper Pustaka front-end to interact with the Koper Pustaka database.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
