Judul: Pengembangan Fitur pada Modul Backend Sistem Pendukung Keputusan Spasial Kesesuaian Lahan Bawang Putih
Abstrak: Permasalahan dalam meningkatkan produktivitas bawang putih adalah sulitnya menentukan lahan yang sesuai. Penelitian sebelumnya telah berhasil mengembangkan modul backend sistem pendukung keputusan spasial untuk melakukan evaluasi kesesuaian lahan bawang putih. Penelitian ini bertujuan untuk melakukan pengembangan dari modul backend pada penelitian sebelumnya. Pengembangan tersebut di antaranya melakukan pembatasan akses pada fitur penilaian kesesuaian lahan, membuat fitur-fitur yang bergantung dengan fungsi penyimpanan fail dapat digunakan, membuat data lokasi lahan pengguna dapat ditampilkan pada peta, memperbaiki penentuan titik tengah data satuan peta tanah (SPT), dan mendapatkan data lama penyinaran terbaru secara otomatis untuk daerah SPT pada data kesesuaian lahan. Tahapan pada penelitian ini yaitu identifikasi dan analisis kebutuhan, pemodelan modul backend, pengembangan modul backend, serta pengujian dan pengunggahan modul backend. Pengembangan menghasilkan 16 tabel baru yang telah dinormalisasi pada basis data. Kemudian, dihasilkan 37 Application Programming Interface baru dan 1 scheduler baru yang telah berhasil diunggah ulang dan diuji., The problem in increasing garlic productivity is the difficulty of determining suitable land. Previous study has succeeded in developing a spatial decision support system backend module to evaluate garlic land suitability. This study aims to improve the backend module developed in the previous study. These developments include restricting access to the land suitability assessment feature, making features that depend on the file storage function usable, making user-entered field location data can be shown on the map, fixing soil map unit (SMU) data midpoint determination, and getting the latest length of irradiation data automatically for SMU area on land suitability data. The stages in this study are identification and analysis of needs, backend module modeling, backend module development, and backend module testing and deployment. Development generates 16 new tables that have been normalized in the database. This study results 37 new Application Programming Interfaces and 1 new scheduler which have been successfully re-uploaded and tested.

Judul: Development of Frontend Module on Spatial Decision Support System for Garlic Land Suitability
Abstrak: Permasalahan dalam pengembangan lahan tanaman bawang putih adalah kurang sempurnanya pertumbuhan bawang putih yang disebabkan oleh tidak sesuainya lahan yang ditanami bawang putih. Penelitian sebelumnya telah mengembangkan sistem pendukung keputusan spasial yang dapat digunakan untuk mengevaluasi kesesuaian lahan bawang putih. Penelitian ini bertujuan untuk memperbarui tampilan pada penelitian sebelumnya dan menambahkan beberapa fitur yang dapat memberikan informasi mengenai kesesuaian lahan bawang putih. Visualisasi peta menggunakan ArcGIS yang terintegrasi dengan API dengan menggunakan framework Next.js dan TailwindCSS dengan metode prototyping sebagai metode pengembangan. Fitur utama yang ada pada sistem berupa fitur yang dapat diakses oleh publik yaitu peta kesesuaian lahan, penilaian kesesuaian lahan, about dan glosarium. Fitur pendukung yang ada pada sistem berupa fitur yang memiliki akses terbatas yaitu unduh berkas data kesesuaian lahan dan memasukkan berkas. Berdasarkan hasil dari pengujian yang dilakukan menggunakan metode blackbox testing, fitur utama dan fitur pendukung mampu berjalan dengan baik., The problem in developing garlic plantations is the incomplete growth of garlic caused by the inappropriateness of the land planted with garlic. Previous research has developed a spatial decision support system that can be used to develop garlic fields. This study aims to update the appearance of previous studies and add some features that can provide information about the availability of garlic fields. Map visualization using ArcGIS which is integrated with the API using the Next.js framework and TailwindCSS with the prototyping method as the development method. The main features in the system are features that can be accessed by the public, namely land maps, land suitability evaluation, about and a glossary. Supporting features available on the system are features that have limited access, namely downloading land suitability data files and input files. Based on the results of the tests carried out using the blackbox testing method, the main features and supporting features are able to run well.

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.
