Judul: Modifying and Migrating Forum Tani API System of Digital Tani Application from Laravel to ASP.NET
Abstrak: Digital Tani (Digitani) IPB adalah aplikasi yang menyediakan sarana pertukaran informasi di bidang pertanian. Namun yang dapat diakses hanya layanan web Digitani dan saat ini aplikasi Digitani belum dapat diakses dari Apple App Store dan Google Play Store dikarenakan belum memenuhi pedoman pengembangan aplikasi terkait keamanan User-Generated Content. Selain itu, framework aplikasi perlu dimigrasi dari Laravel ke ASP.NET agar mendukung skalabilitas jangka panjang serta agar sesuai dengan pedoman Apple dan Google. Oleh karena itu, sistem API Digitani juga harus migrasi ke framework dengan lingkungan pengembangan yang lebih aman dan skalasi yang lebih mudah seperti ASP.NET. Penelitian ini membahas pengembangan back-end sistem API dengan metode prototyping. Modifikasi dan migrasi sistem API Forum Tani memungkinkan tim pengembang Digitani IPB untuk melakukan skalasi dengan lebih mudah. Penelitian ini menghasilkan 17 endpoint Forum Tani dengan hasil yang sesuai dengan performa yang lebih baik dari framework sebelumnya. Walaupun demikian, Digitani IPB yang diluncurkan kembali ke Apple App Store dan Google Play Store masih menggunakan framework sebelumnya. Hal ini karena sistem API baru belum migrasi beberapa layanan lainnya di luar cakupan penelitian ini., Digital Tani (Digitani) IPB is an application providing a means of exchanging information in the agricultural sector. However, only the Digitani web service can be accessed and currently the Digitani application is unavailable on the Apple App Store and Google Play Store due to not meeting the application development guidelines regarding security on User-Generated Content. Besides that, the application framework needs to be migrated from Laravel to ASP.NET to support long-term scalability and to comply with the guidelines of Apple and Google. Therefore, the API system of Digitani must also be migrated to a framework with a safer development environment and easier scalability like ASP.NET. This research discusses the development of back-end API system using prototyping method. Modification and migration of Forum Tani’s API system enables the development team to escalate the application with ease. This research produces 17 Forum Tani endpoints that returns expected results with better performance than the previous framework. Even so, Digitani IPB that has been reuploaded to the Apple App Store and Google Play Store is still using the previous framework. This is due to the new API system is still under development with migrating a few other services outside the scope of this research.

Judul: Pengembangan Backend Forum Tani pada Digital Tani dengan Metode Prototyping
Abstrak: Indonesia adalah negara agraris yang sebagian besar masyarakatnya bermata pencaharian sebagai petani. Kurangnya edukasi yang merata mengenai pertanian mengakibatkan sulitnya pemahaman tentang permasalahan baru yang dihadapi petani. Adanya forum online dapat membantu petani dalam mendiskusi permasalahan baru dengan lingkup yang lebih luas. Tani Center IPB mengembangkan aplikasi Digital Tani sebagai one stop solution untuk masalah pertanian Indonesia. Penelitian ini bertujuan untuk mengembangkan backend forum tani pada aplikasi Digital Tani dengan metode prototyping. Sistem dikembangkan dengan menggunakan framework Laravel dengan arsitektur Model, View, Controller (MVC). Hasil pengembangan diuji menggunakan blackbox testing dan telah berhasil memenuhi Minimum Viable Product (MVP) dengan iterasi yang dilakukan sebanyak 2 kali., Indonesia is an agricultural country where most of the people make a living as farmers. The lack of equitable education about agriculture makes it difficult to understand the new problems faced by farmers. The existence of online forums can help farmers in discussing new problems with a wider scope. Tani Center IPB developed the Digital Tani application as a one stop solution for Indonesian agricultural problems. This study aims to develop a farmer forum backend on the Digital Tani application using the prototyping method. The system was developed using the Laravel framework with Model, View, Controller (MVC) architecture. The results of the development were tested using blackbox testing and had successfully met the Minimum Viable Product (MVP) with 2 iterations.

Judul: Sintesis dan Pencirian Kompleks Fe(III)-Kuersetin
Abstrak: Quercetin belongs to flavonols which is able to chelate metal ions. Quercetin may chelate metal ions at 3’,4’-catechol, 3- or 5-hydroxycromone sites. In this study, quercetin was complexed with Fe(III). The complex with Fe(III) ions from FeCl3·6H2O was more stable than the complex derived from Fe(NO3)3·9H2O. The quercetin was yellow in color and showed maximum wavelengths (λ􀭫􀭟􀭶) at 250 and 370 nm. The Fe(III)-quercetin complex from Fe(NO3)3·9H2O was yellowish green with 􀟣􀭫􀭟􀭶 at 280 and 420 nm, whereas that from FeCl3·6H2O was dark green with 􀟣􀭫􀭟􀭶 at 280 and 430 nm. The 􀟣􀭫􀭟􀭶 shift indicated that the complex was formed at 3-hydroxychromone site. The Fe(III)- quercetin complex was formed with 1:1 metal-ligand mole ratio based on atomic absorption spectrophotometry analysis and the X-ray diffractogram showed that the crystallinity of the complex was 37%.
