Abstract

Investment is an activity in the present to obtain profits in the future. One method of investment assessment is calculating Net Present Value (NPV) using Discounted Cash Flow (DCF). To determine the right time to carry out an investment in order to obtain maximum profits, it is necessary to determine a time limit for when the investment should be carried out or not. Then, the threshold curve (optimal implementation time limit) for the investment will first be determined. After obtaining the threshold curve for each investment option, the NPV value for each investment option will then be determined. The best investment choice is the one that provides the highest NPV value. The metaheuristic method is an effective optimization method for determining the optimal investment implementation time limit (threshold curve). One metaheuristic method for determining threshold curves is the Spiral Dynamics Optimization algorithm developed by Kenichi Tamura and Keiichiro Yasuda, a search algorithm inspired by phenomena in nature such as water speed, air pressure speed, Nautilus Shells, and spiral galaxy shapes. The results of this research are areas that are above the threshold curve, which can implement the project, while areas that are below the curve are not recommended for implementing the project.

Abstract

Literasi digital menjadi kebutuhan penting dalam pembangunan desa berbasis komunitas di era digital. Melalui kolaborasi antara pemerintah desa, BPS, dan agen statistik mahasiswa, Desa Rebo didorong mengembangkan literasi digital dan penyajian data statistik secara visual. Kegiatan pengabdian ini memperkuat kapasitas aparatur desa dalam mengelola teknologi dan informasi, mendukung program smart village, serta mempercepat terwujudnya desa mandiri berbasis data dan teknologi secara berkelanjutan. Pengabdian ini bertujuan untuk memberdayakan Agen Statistik (ANTIK) dalam meningkatkan literasi digital serta pemahaman terhadap sistem keuangan desa di Desa Rebo, Kecamatan Sungailiat, Kabupaten Bangka. Kegiatan dilakukan secara kolaboratif antara akademisi Universitas Bangka Belitung, BPS Provinsi Kepulauan Bangka Belitung, Agen Statistik serta perangkat Desa Rebo. Rangkaian kegiatan dimulai dengan sambutan dari Kepala Desa Rebo dan dilanjutkan dengan  pemaparan materi mengenai Sistem Keuangan Desa yang dilanjutkan dengan pelatihan penggunaan Platform Canva untuk pembuatan infografis statistik data kependudukan oleh tim dibantu oleh Agen Statistik. Evaluasi kegiatan dilakukan melalui penyebaran kuesioner kepuasan mitra menggunakan skala Likert. Hasil menunjukkan bahwa mayoritas peserta menyatakan setuju dan sangat setuju terhadap semua aspek kegiatan, dengan respons tertinggi pada kejelasan materi (67% sangat setuju). Kegiatan ini mendapat dukungan penuh dari mitra dan menghasilkan rekomendasi positif dari peserta untuk keberlanjutan program serupa di masa mendatang.
