Judul: Pengembangan Aplikasi Mobile Profiling untuk Profiling Petani Kelapa Sawit Mandiri: Solusi Data untuk Ketertelusuran Rantai Pasok
Abstrak: This project was released to handle the challenges faced by smallholder farmers in Indonesia regarding palm oil supply chain traceability. A mobile application was developed to improve data collection and transparency. The palm oil industry plays a key role in the Indonesian economy but faces pressure to ensure sustainable practices. Traceability of Fresh Fruit Bunches (FFB) is crucial, and manual recording systems used by many smallholders are prone to errors and manipulation. This project aimed to develop a user-friendly mobile application for profiling palm oil farmers. The application allows farmers to register, record land data (including automatic area calculations based on GPS pinpoints), and upload profile information. Integration with a Firebase database ensures secure data storage and access for relevant stakeholders. A verification process is planned, in which cooperatives verify newly submitted farmer data before they can sell FFB. This application has the potential to streamline traceability efforts, improve transparency, and empower smallholder farmers in the palm oil supply chain. Future development will focus on hosting the application publicly and implementing location-based notification features.

Judul: Pengembangan Front-End Aplikasi Control Monitoring Perkebunan Inagrow Berbasis Mobile Pada Sisi Ahli Praktisi dan Pemilik Lahan
Abstrak: Perkebunan kopi memiliki potensi besar dalam meningkatkan perekonomian di Indonesia. Namun, proses pengawasan lahan perkebunan yang dilakukan masih kurang optimal, karena proses pelaporan perkebunan masih dilakukan secara manual. Berdasarkan masalah tersebut dibangunlah aplikasi control monitoring perkebunan. Penelitian ini berfokus pada pengembangan front end aplikasi mobile untuk pemilik lahan dan ahli praktisi. Metode yang digunakan dalam pengembangan aplikasi adalah prototyping dan dilakukan iterasi sebanyak dua kali. Tujuan pengembangan aplikasi adalah mempermudah pemilik lahan dalam melakukan pengawasan terhadap lahan perkebunan dan mempermudah ahli praktisi dalam memberikan konsultasi secara online tanpa harus pergi ke lahan perkebunan. Fitur utama yang dikembangkan untuk pemilik lahan adalah mengirim task dan melihat laporan perkebunan. Sedangkan fitur utama untuk ahli praktisi adalah membuat pesan chat untuk memberikan konsultasi terkait masalah perkebunan. Aplikasi masih perlu perbaikan dari segi user interface dan user experience.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
