Daily Nusantara, Surabaya – Amidst the rise of modern building material supermarkets, the local Micro, Small, and Medium Enterprises (MSME) or Usaha Mikro, Kecil, dan Menengah (UMKM) sector remains a sturdy backbone of the national economy. A vivid example of this resilience is seen in TB. Sinar Sejahtera, a family-owned building material store located at Gg. Perintis Utama No.110, Gading, Kenjeran, Surabaya.
Now managed by the second generation, TB. Sinar Sejahtera is more than just a place for construction transactions; it is a social institution that blends practical business needs with local wisdom.
Management Based on Trust
For many UMKM owners in Indonesia, a business is a living legacy. At TB. Sinar Sejahtera, the transition of leadership to the second generation brings a unique challenge: how to maintain traditional values while implementing effective managerial functions.
In-depth analysis of this store reveals a fascinating phenomenon in the implementation of staffing and controlling functions. Unlike Western management theories that tend to be rigid and hierarchical, TB. Sinar Sejahtera applies a Family-like Culture. Here, the boundaries between superiors and subordinates dissolve into mutual trust. Employee loyalty is nurtured not just through wages, but through genuine care for personal milestones and life events.
“This natural family-like culture often serves as a highly effective substitute for formal management systems within the local context,” stated a member of Group 6 in their analysis report.
Complete Solutions for Home Construction
As a merchandising business, TB. Sinar Sejahtera positions itself as a trusted partner for the residents of Kenjeran and surrounding areas. The store serves various market segments, ranging from individual homeowners doing small-scale renovations to local contractors requiring routine supplies.
The availability of comprehensive stock is a major draw. Their featured products include various types of cement, sand, reinforcement steel, a wide selection of floor and wall tiles, interior/exterior paints, and essential tools such as shovels and hoes.
Service Beyond Selling
What sets TB. Sinar Sejahtera apart from its competitors is the added value provided to customers. Clients can enjoy Free Material Consultation to get technical advice on the types of materials that best fit their budget and project specifications.
Logistical excellence is also a top priority. Supported by experienced staff such as Mas Jumani and Pak Indro, TB. Sinar Sejahtera guarantees that bulk deliveries are handled quickly, punctually, and safely to the customer’s construction site. The presence of this store proves that even in the digital age, a personal touch, trust, and relationship-based management remain the keys to building a sustainable business ecosystem.
