Abstract

Kurikulum Merdeka yang dicanangkan oleh Pemerintah melalui Mendikbudristek pada tahun 2022 memberikan kebebasan pada sekolah dalam mengatur alokasi waktu dan materi pelajaran. Sementara itu siswa juga diberikan kebebasan memilih pelajaran yang sesuai dengan bakat dan minat, serta rencana karir yang akan dipilih. Kebebasan yang diberikan ini juga memberikan permasalahan bagi sekolah, guru dan siswa. Permasalahan tersebut antara lain terkait dengan kurangnya wawasan para siswa tentang berbagai profesi yang dapat ditekuni, lingkup pekerjaan, prospek karir, serta kaitannya dengan mata pelajaran yang harus dipilih untuk menunjang profesi tersebut. SMA Kristen Trimulia sebagai salah satu sekolah yang akan melaksanakan kurikulum Merdeka, menghadapi permasalahan yang sama. Salah satu upaya sekolah untuk mengatasi hal tersebut adalah mengundang berbagai mitra perguruan tinggi untuk memberi wawasan pada siswa tentang bidang studi yang ditawarkan. Kegiatan literasi aktuaria ini merupakan kegiatan pengabdian kepada masyarakat beberapa dosen Program Studi Sarjana Matematika UNPAR. Kegiatan ini bertujuan memperkenalkan matematika dan statistika yang terkait dengan aktuaria, sesuai dengan tingkat pengetahuan mereka sebagai siswa SMA. Melalui kegiatan ini siswa diharapkan memperoleh wawasan terkait aktuaria dan profesi aktuaris, yang dapat membantu siswa untuk memutuskan apakah profesi aktuaris merupakan pilihan karir yang cocok untuk mereka.

Abstract

The paper focuses on developing an inventory model for deteriorated item when demand is time- and inventorydependent. Deteriorated items can usually be found in items such as vegetables, fruit, milk, chemical product, pharmaceutical and it needs special attention in managing this kind of inventory. We model the inventory control for these items by a mathematical model involving time- and inventory-dependent demand and considering the backorder policy in handling shortages. The developed model aims to find the optimal time between replenishment and when inventory drops to zero, which minimizes the total inventory cost. The total inventory cost consists of the purchase cost, the order cost, the holding cost, and the shortage cost. Sensitivity analysis is performed to analyse the effect of changing the parameters’ values to the time between replenishment, when inventory drops to zero, the order quantity, and the total inventory cost. The finding shows that changing the parameters’ values of deterioration rate, demand, unit holding cost, unit holding cost and unit shortage cost will have an impact on the time between replenishment, time when inventory drops to zero, order quantity, and inventory cost.

Abstract

Strengthening Village-Owned Enterprises (BUMDes) is crucial for reducing economic disparities in rural areas and promoting sustainable community development. While previous studies have primarily focused on financial structures and regulatory frameworks, this research adopts a participatory approach that actively engages local stakeholders in capacity-building efforts. Using BUMDes Mekarsari in Garut Regency as a case study, the study examines how participatory strengthening programs enhance the socio-economic resilience of rural communities. Employing qualitative methods—including in-depth interviews and field observations—it identifies key factors influencing BUMDes effectiveness, such as continuous training, institutional collaboration, and improved access to finance. The findings reveal that a participatory model not only fosters community engagement but also improves business sustainability and expands economic opportunities. In particular, the involvement of women and local artisans demonstrates the program’s inclusivity and potential for social transformation. Moreover, the integration of digital marketing strategies has opened new market access, further supporting rural entrepreneurship. To maximize practical impact, the study offers concrete policy recommendations, including strengthening institutional support for BUMDes, fostering multi-sector partnerships, and enhancing financial accessibility through local and national policies. These insights contribute to a more inclusive framework for rural economic empowerment, providing policymakers with a strategic foundation for designing community-driven BUMDes programs that ensure their long-term success as catalysts for local development.
