Abstract

Proses distribusi barang pada suatu industri memerlukan bentuk efisiensi dalam pemilihan jalur terpendek yang akan dilalui seorang salesman. Secara matematis, pemilihan jalur terpendek merupakan suatu permasalahan optimasi yang disebut Travelling Salesman Problem (TSP). Terdapat banyak metode yang dapat diterapkan untuk menemukan solusi dari TSP, salah satunya Evolutionary Discrete Firefly Algorithm (EDFA) yang merupakan metode metaheuristik terbaru yang ditemukan oleh Jati dan Suyanto (2011) sebagai perkembangan dari Firefly Algorithm (FA) yang hanya didesain untuk permasalahan kontinu. Penelitian ini bertujuan untuk menjelaskan penerapan EDFA dalam penyelesaian TSP. Data yang digunakan dalam penelitian ini merupakan data kasus TSP berupa koordinat titik kota yang diambil dari database TSP Libary (TSPLIB) dengan 7 jenis kasus berbeda yaitu Ulysses16, Ulysses22, Eil51, Berlin52, St70, Rat99, dan Gr202. Kasus-kasus tersebut diselesaikan dengan menerapkan EDFA untuk menemukan solusi optimalnya melalui beberapa langkah yang terdapat dalam algoritma ini. Penyelesaian kasus TSP melalui EDFA juga dilakukan menggunakan bantuan program simulasi untuk mempermudah pehitungan. Hasil penelitian menunjukkan bahwa EDFA sebagai perkembangan FA telah berhasil diterapkan untuk kasus TSP yang memiliki solusi dalam ruang diskrit. Simulasi program EDFA yang diterapkan pada kasus-kasus tersebut memberikan solusi lebih baik pada beberapa kasus dengan hasil jarak optimal yang lebih pendek dibandingkan jarak optimal yang telah ditemukan sebelumnya.Kata Kunci: TSP, EDFA, firefly, solusi optimal.

Abstract

Balancing caregiving duties with multiple responbilities is a persistent challenge for housewives, particularly those managing micro, small, and medium enterprises (MSMEs). Bapukung, a traditional swaddling practice from South Kalimantan, offers a potential solution by improving infant sleep quality and providing mothers with uninterrupted time to manage household and business tasks. This study investigates the influence of Bapukung on the productivity and role balance of housewives using a quantitative approach with Structural Equation Modeling-Partial Least Squares (SEM-PLS). Data were collected from 30 respondents in South Kalimantan through structured questionnaires. Results reveal that Bapukung significantly influences both productivity (β = 0.816, p < 0.05) and role balance (β = 0.787, p < 0.05). These findings align with the Resource-Based View (RBV) and Balanced Scorecard frameworks, demonstrating how cultural practices can serve as strategic resources to enhance time management and efficiency. The study contributes to the integration of local wisdom into modern management theories, offering practical implications for family welfare programs and entrepreneurship training. Future research should explore the scalability of Bapukung across diverse cultural contexts and its long-term influence on family dynamics and maternal well-being.

Abstract

The community service partners are housewives in Cindai Alus Village, Banjar Regency, who, in addition to their domestic roles, are also actively managing home-based microenterprises, particularly in the production of traditional Banjar snacks. This condition presents challenges, as most of them still have toddlers who require full attention, often disrupting the continuity of production. The program was implemented to enhance the ability of homemakers to manage their time, balance family roles with productivity, and reintroduce the traditional bapukung method, which functions to soothe children, support better sleep, and promote child development. The approach included socialization, training, and hands-on practice in utilizing sasirangan fabric as a material for the bapukung cradle, while also providing economic value through the development of handicraft skills. The results of the program indicate an increased understanding of daily time management, improved skills in producing sasirangan fabric products, and greater awareness of the benefits of bapukung in reducing interruptions during production activities. By applying this method, homemakers can allocate their time more effectively, thereby improving business productivity. This program concludes that strengthening the capacity of homemakers through traditional and innovative approaches can encourage economic welfare while simultaneously preserving local wisdom.
Model Struktural Prediktif Kinerja Adaptif dan Study–Life Balance: Peran Kapabilitas Strategis Dinamis dengan Bapukung sebagai Sumber Daya Kultural: Structural Predictive Model of Adaptive Performance and Study–Life Balance the Role of Dynamic Strategic Capabilities with Bapukung as a Cultural Resource Prabowo, Sigit Dwi; Cahya, Nila; Rizqina, Sila; Saufi, Muhammad; Susanti, Dewi Sri

Abstract

The transition into a higher education environment often triggers academic pressure demanding optimal adaptive performance and a balance between study and personal life. Amidst modernization challenges, the local wisdom value of Bapukung holds strategic potential as an often-overlooked internal resource for self-management. This study aims to construct a predictive structural model to explain the mediating mechanism of dynamic strategic capabilities in the relationship between cultural affiliation and student performance outcomes. Data were collected via a survey of 81 first-year female students in South Kalimantan and analyzed using the Regularized Structural Equation Modeling method with the Least Absolute Shrinkage and Selection Operator penalty. This statistical approach was applied to perform simultaneous variable selection to generate precise parameter estimates within a limited sample size. Analysis results indicate that cultural affiliation significantly builds the capabilities of sensing, seizing, and reconfiguring resources. A crucial finding from the model selection is a unique role specialization: the reconfiguring capability dominantly determines adaptive performance, while the seizing capability exclusively determines study-life balance. This study concludes that local culture serves as a vital foundation for developing modern self-management competencies, in which mental flexibility is the key to academic achievement and decisiveness is the determinant of life well-being.
