Industry

Pennyu Group is an Indonesian manufacturing company that produces water tanks, chemical tanks, bio-septic tanks, and biogas digesters for industrial and residential use.
In addition to tanks, Pennyu also manufactures sanitary ware and plumbing products such as water filters, faucets, kitchen sinks, and wastewater treatment solutions throughout Indonesia.

Pennyu manufactures water tanks with technical advantages such as 0 Lux technology, 4-layer construction, a capacity 12% greater than the nominal capacity, and so on. However, these advantages are not easily understood from text or standard product photos alone.
On the other hand, Pennyu also offers a variety of products with different combinations of capacity, color, and size. Therefore, potential buyers need guidance to find the right product for their needs.
Primary Objective
To build a water tank product catalog website that showcases the technical advantages of each product and makes it easy for users to find the right product on their own.
Water tanks and sanitary ware are highly technical products with specific market segments. The information is generally easier for contractors and property developers to understand. For the general public, technical information can be difficult to grasp if presented as-is.
Technologies like 0 Lux cannot be explained through text alone. Without the right visuals, potential buyers cannot distinguish Pennyu’s products from those of its competitors
Pennyu manufactures water tanks in a wide variety of capacity, color, and size combinations. Without a filtering system, users have a hard time choosing a product that meets their needs.
Many users do not know the actual tank capacity. Without guidance and calculations, they have to contact the sales team, which may provide incorrect information or recommendations.
Users interested in Pennyu products or who have product complaints have no direct way to contact the company.
Grapiku built a product catalog website for Pennyu water tanks with two main focuses: clearly showcasing the technical advantages of each product, and providing a system that helps users find the right product on their own.
The technical structure was also designed to be easily indexed by Google from the start, so that Pennyu’s manufacturing website can grow organically without relying on ads.
Aligning business goals, user targets, positioning, and the key requirements for the Pennyu Group website. This phase also includes identifying communication challenges, feature priorities, and project success metrics.
Analysis of direct and indirect competitors to map out visual benchmarks, information architecture, features, positioning, and opportunities for Pennyu Group to differentiate itself.
Designing information architecture based on the retail and business (B2B) user journey.
Organize the content into a wireframe. Focus on navigation and the information hierarchy of the product and project pages.
Implementation of the visual system in accordance with Pennyu Group’s brand guidelines. Consistent UI component design across all pages, including the product catalog, project showcase, and articles.
Development of a dynamic website using a custom WordPress setup. This includes product catalog development, content development, integration, and efficient code optimization.
Comprehensive testing across devices and browsers. Migration to the pennyu.co.id domain, integration of analytics, security, and basic SEO. Plus, a training session for the Pennyu team on self-managed content management.

Every Pennyu water tank product has advantages that aren’t easy to explain in words alone. Grapiku translates technical advantages such as 0 Lux technology, 4-layer construction, and 12% greater capacity into visual illustrations that can be immediately understood on the product page.
As a result, potential buyers can understand why Pennyu products are different without needing additional explanations from the sales team.

On the landing page for each Pennyu water tank product, users can select their desired color and size. The product visualization updates in real time based on their selections.
When users click the WhatsApp button, the system automatically populates the message with details of the selected product, for example: “Hello Pennyu, I’d like to ask about the Pennyu One 1,000-liter tank in orange.”
Sales representatives receive specific inquiries without needing to start from scratch.

With this feature, users simply enter the number of occupants and the building type, and the system recommends the appropriate capacity and directs them to the relevant product page.

Grapiku developed a lead generation system for the Pennyu website to optimize the lead acquisition process from product catalog requests and reseller registration to newsletter subscriptions.
Every user who wants to access the catalog, register as a reseller, or receive updates is required to fill out their personal information first. The collected data is then integrated into a prospect database that Pennyu’s sales team can use for follow-ups, nurturing, and more targeted remarketing activities.

The Pennyu website was built on a technical foundation that supports long-term SEO growth, ranging from a well-organized content structure and clear navigation to a mobile-responsive design that ensures an optimal user experience across various devices.
Each page is designed to be easily indexed by Google and to have a good chance of appearing in relevant search results, allowing the website to continue growing organically as more content is added.
Traffic skyrocketed in the first 6 months thanks to a well-structured update to the website’s technical architecture.
Simulations of occupant needs and building types to streamline the user journey before the purchase stage.
Eliminates communication friction with a system that converts selection filters on the product page into ready-to-send instant message drafts.
