Home-based traditional ice cream (es puter) industries in the Special Region of Yogyakarta continue to face inefficiencies in their production processes. Manual methods still dominate, particularly in the ice block crushing and ice cream stirring stages, which can take up to two hours and heavily rely on human labor. This condition not only hampers productivity but also increases operational costs.
To address this issue, a student team from Universitas Gadjah Mada (UGM) has developed an innovative tool called Enu-Cenner (Enumerator and Ice Spinner), which functions as both an automatic ice block crusher and an ice cream mixer.
The tool is designed to accelerate the production process and reduce dependence on manual labor, making home-based ice cream production more efficient and economical.
In implementing their innovation, the team collaborated with a local home industry, Yono Es Puter dan Es Krim, located in Sariharjo, Sleman.
The adaptation of this technology was carried out by a team consisting of Najmu Tsakib (Heavy Equipment Management and Maintenance Engineering), Marshall Gibran Wisnujati (Mechanical Engineering), Halim Kusuma Putra (Mechanical Engineering), Amalisa Putri Defita (Agronomy), and Endra Tegar Sejati (Electrical Engineering Technology).
The team worked under the supervision of Ma’un Budiyanto, a lecturer at UGM Vocational College (SV UGM).
As the supervising lecturer, Budiyanto explained that Enu-Cenner was born from interdisciplinary collaboration within the Student Creativity Program for Science and Technology Application (PKM-PI).
The technology focuses on developing a simple automatic system that can accelerate the traditional ice cream production process without compromising product quality.
“The involvement of students from various study programs demonstrates UGM’s commitment to producing innovations that are practical and beneficial for the community,” said Budiyanto on Saturday, Oct. 18, 2025.
Regarding its function, Endra Tegar Sejati explained that the device integrates two main systems, an ice block crusher and an ice cream spinner, into a single unit.
“Technically, the ice block is fed into the crusher and broken into small pieces, which are then directed into the container holding the ice cream cylinder,” he said.
He further noted that the spinning process can be adjusted using a frequency inverter converter, ensuring the ice cream achieves an even and smooth texture.
“The tool is also equipped with safety features such as an MCB (Miniature Circuit Breaker) and an emergency stop button, making it safe for the partners to operate,” he added.
Echoing this, Marshall Gibran Wisnujati stated that the innovation aims to replace manual processes with an integrated system.
“With this innovation, production time can be significantly reduced, and additional labor costs can be minimized,” he said.
Addressing challenges faced by small-scale industries, Halim Kusuma Putra expressed hope that Enu-Cenner would not only benefit their partner but could also be adopted by other traditional ice cream producers.
This innovation reflects the strong commitment of UGM students to support local MSMEs in enhancing productivity, especially in the home-based industrial sector.
“Enu-Cenner is expected to become a sustainable solution for traditional ice cream entrepreneurs in overcoming production challenges,” concluded Amalisa Putri Defita.
