    Unikom Officially Send Off 560 Students For The 2026 “Kkn Berdampak” Program, Promoting Waste Management Initiatives In Coblong District

    BANDUNG, UNIKOM — Wednesday, August 12, 2026, the Universitas Komputer Indonesia (UNIKOM) officially sent off 560 students participating in the 2026 UNIKOM Impact Community Service Program (KKN) to contribute directly to the community, specifically by supporting waste management in Coblong Subdistrict, Bandung City, under the theme “Tracked Waste, Organized Environment.” Held at the UNIKOM Dago Campus Field, the event was attended by the UNIKOM Rector and Chair of the West Java APTISI, Prof. 3. Prof. HC. Dr. Ir. Eddy Soeryanto Soegoto, M.T., Vice Rector I for Academic and Student Affairs Prof. Dr. Hj. Umi Narimawati, Dra., S.E., M.Si., M.Pd., the Field Supervisors (DPL), and all participants of the UNIKOM 2026 Impactful Community Service Program.

    UNIKOM Rector, Prof. 3 Prof. HC. Dr. Ir. Eddy Soeryanto Soegoto, M.T., in his remarks, expressed his pride in the enthusiasm, unity, and integrity of the students who will carry out the Impactful Community Service Program. According to him, this activity is not merely an academic agenda but a tangible form of student contribution to the community as well as support for the West Java Provincial Government’s program to address waste management issues. “I am very pleased and proud of the solidarity shown by the community and UNIKOM students, as well as the integrity they have demonstrated. Today, I officially send off UNIKOM students to carry out their KKN in the field,” said Prof. Eddy.

    Furthermore, Prof. Eddy emphasized that UNIKOM students are expected to serve as pioneers and role models for other universities in raising public awareness about waste management. Students are not only asked to help manage waste directly but also to educate the community on the importance of sorting waste by type, such as residual waste and plastic. “Most importantly, the government has asked our students to educate the community on how to sort waste—distinguishing between residual waste, plastic, and other categories. This will help foster a habit within our community, particularly in Coblong,” Prof. Eddy stressed.

    According to him, the habit of sorting waste at the community level will make a significant contribution to creating a cleaner environment while also helping the government resolve waste management issues. Prof. Eddy also noted that UNIKOM’s Impact-Driven Community Service Program is expected to serve as a model that can be replicated by other private universities in West Java. As Chair of APTISI West Java, Prof. Eddy outlined plans to encourage other universities to follow the example set by UNIKOM students in addressing environmental issues. “These UNIKOM students serve as a model for other private universities throughout West Java to emulate,” he stated.

    The program was designed with a regional approach, in which universities take on the role of mentoring a single subdistrict. UNIKOM selected Coblong Subdistrict as the implementation area because it is located in the vicinity of the campus. At the end of his remarks, Prof. Eddy expressed hope that the best practices carried out by UNIKOM students in Coblong could eventually be developed and shared with other universities, both in West Java and across various regencies and cities. In addition, he also noted that the local government has recognized the role of UNIKOM students in helping to resolve community issues. According to him, UNIKOM’s involvement in this program aligns with the government’s hope that higher education institutions not only serve as educational institutions but also have a tangible impact on their surrounding communities.

    Meanwhile, the First Vice Rector for Academic and Student Affairs, who also serves as the Executive Chair of UNIKOM’s Impactful Community Service Program (KKN Berdampak), Prof. Dr. Hj. Umi Narimawati, Dra., S.E., M.Si., M.Pd., expressed her appreciation to all students, academic programs, faculty members, and field supervisors who supported the implementation of the program. She emphasized that the Impact-Driven Community Service Program (KKN Berdampak) is a manifestation of UNIKOM’s commitment to the community and a means for students to learn firsthand from real-world challenges. “This is a manifestation of UNIKOM’s commitment and love for its students. We learn in the real community,” she said.

    Prof. Umi explained that the Impactful Community Service Program (KKN Berdampak) is not merely an activity to “clean up trash,” but rather a learning process that encourages students to understand and help solve various community issues. This program is also being integrated into the curriculum. The academic credit load for KKN can be adjusted according to each study program; in fact, some programs have proposed up to approximately 20 SKS. This demonstrates strong support from various degree programs at UNIKOM for the Impactful Community Service Program. “It’s not just about solving a single problem, but addressing the various challenges facing the community,” explained Prof. Umi.

    For the 2026 Impactful Community Service Program, UNIKOM dispatched 560 students to participate in activities in Coblong Subdistrict. This number reflects UNIKOM’s commitment to making a broader contribution to the waste management program in the city of Bandung. The students will be accompanied by Field Supervisors, who play a crucial role in guiding, directing, and evaluating the implementation of activities in the field.

    Prof. Umi urged all students to maintain discipline, abide by the rules in the areas where they are assigned, and uphold the reputation of their alma mater. “Maintain proper conduct and uphold the good name of UNIKOM, which we all love. Share the positive aspects of UNIKOM while you’re there,” she told the students. She also reminded them to comply with all administrative requirements and KKN activities, including filling out attendance sheets and preparing reports.

    The send-off ceremony was marked by the symbolic dismissal of the “KKN Berdampak” students by the UNIKOM Rector. Two student representatives Arkan Ghifari from the Architecture Engineering program and Renata Rufaidah from the International Relations program stepped forward to participate in the send-off ceremony, which included the presentation of program insignia and the handover of ID cards. Following the ceremony, the UNIKOM 2026 “KKN Berdampak” students were officially sent off to carry out their community service.

    Through the 2026 Impactful Community Service Program, UNIKOM hopes that students will be able to make measurable and sustainable contributions to the community. In addition to providing education on waste sorting and management, students are expected to serve as agents of change who raise public awareness and encourage the development of lifestyle habits that are more environmentally conscious. Guided by the motto “Tracked Waste, Organized Environment,” 560 UNIKOM Impact Community Service Program students are ready to carry out their duties in Coblong Subdistrict, bringing their academic enthusiasm, social commitment, and the good name of their alma mater to create a positive impact on the community.

  • Strengthening Its Global Presence: Director Of International Programs Unikom Appears As Keynote Speaker At Mahasarakham University In Thailand, Discussing Topics Ranging From Smart Universities To Student Mobility

    Strengthening Its Global Presence: Director Of International Programs Unikom Appears As Keynote Speaker At Mahasarakham University In Thailand, Discussing Topics Ranging From Smart Universities To Student Mobility

    BANDUNG, UNIKOM – The Universitas Komputer Indonesia (UNIKOM) commitment to expanding its international academic network while providing global experiences for students continues to be strengthened through various collaborative programs with partner universities abroad. One such initiative was realized through the participation of UNIKOM’s Director of International Programs, Dr. Senny Luckarydi, S.P., M.M., as a keynote speaker at an international conference held over a week from July 20–27, 2026, at Mahasarakham University in Thailand.

    Dr. Senny Luckarydi, S.P., M.M., had the opportunity to accept an invitation from Mahasarakham University, one of the largest public universities in Northern Thailand with approximately 50,000 students. The invitation came from the Faculty of Education in connection with an international conference addressing various strategic issues in the development of education and university governance.

    On this occasion, Dr. Senny was entrusted to deliver the keynote speech on the theme “Smart University Management.” According to him, the concept of a smart university cannot be interpreted merely as the digitization of learning or a shift in services from conventional systems to online platforms, but rather as a comprehensive transformation in university management. “A smart university is not merely a transition from offline to online, but also a massive transformation in terms of services, governance and management, infrastructure, and so on,” said Dr. Senny.

    Furthermore, Dr. Senny explained that the transformation toward a smart university requires integrated changes across various aspects of higher education management. This ranges from how universities provide services to the academic community, to establishing adaptive governance, developing effective management systems, and providing infrastructure capable of supporting a technology-based educational ecosystem.

    Dr. Senny’s presence as a keynote speaker is also part of the implementation of UNIKOM’s international collaboration with Mahasarakham University, which not only focuses on inter-institutional academic activities but also opens opportunities for students to gain cross-border learning experiences through student mobility programs. “This includes collaboration on the International Program because we also send students to participate in mobility programs there,” he explained.

    In practice, UNIKOM students participating in the mobility program come from the International Relations (IR) and Information Systems programs. The program provides students with the opportunity to experience an international academic environment firsthand, broaden their horizons, build networks, and interact with students from diverse cultural backgrounds.

    This collaboration will also continue to be developed in both directions. In November 2026, Mahasarakham University is scheduled to send 10 students and 4 faculty members to visit UNIKOM. The delegation’s visit is expected to further strengthen academic interactions and open up new opportunities for collaboration between the two institutions. In addition to serving as a keynote speaker, this series of international activities also provided an opportunity for Dr. Senny to share her academic knowledge and experience, including through a publication workshop designed to build participants’ capacity in understanding the processes and strategies of scientific publishing.

    According to Dr. Senny, the sustainability of international cooperation must be directed toward tangible benefits for both the institutions and the students. Collaboration does not end with ceremonies or the signing of cooperation agreements; rather, it must be realized through various activities that enrich students’ experiences and enhance the quality of education. “Our hope is that our cooperation will grow in both scope and impact. Ultimately, the goal is to improve the quality of education and provide enrichment for students offering them engaging experiences so that their knowledge can be better applied and they are more motivated to pursue their studies,” she explained. Strengthening cooperation with international universities is part of UNIKOM’s efforts to build an increasingly open and globally oriented educational ecosystem. Through student exchange programs, international conferences, academic workshops, and various other forms of collaboration, UNIKOM continues to encourage students and the academic community to develop not only academic competencies but also global experiences and perspectives. These efforts also underscore UNIKOM’s commitment as a Digital Entrepreneurial University to providing an education that adapts to technological advancements, is open to international networks, and offers learning experiences relevant to the needs of the global community.

    Directorate Inbiskom Unikom Celebrates The 3rd Anniversary Of The Smart Cooperative And Market Day 2026, Encouraging Students To Become Young Entrepreneurs In The Digital Age

    BANDUNG, UNIKOM – The Universitas Komputer Indonesia (UNIKOM) continues to strengthen the entrepreneurial ecosystem on campus by hosting the “Coop-Preneur Fest: Creative Action, Safe Innovation” event, which is held in conjunction with the celebration of the 3rd anniversary of the UNIKOM Smart Cooperative (KOSMART) and UNIKOM Market Day, on Monday and Tuesday, July 20–21, 2026. The event served as both a learning space and a platform for students to develop their creativity, showcase products, gain business experience, and hone their ability to leverage digital technology to expand their markets.

    Held in the Lobby of UNIKOM’s Smart Building, the Coop-Preneur Fest 2026 event showcased students’ entrepreneurial spirit through various booths displaying products born of creativity and innovation. On the first day, 95 student booths participated in Market Day, while the entire event involved 622 students divided into 260 business groups. Also present at the event was Vice Rector II for Resources, Assoc. Prof. Dr. Agus Riyanto, S.T., M.T., CSBA., Vice Rector IV for Digital Technology & ICT, International Programs & Center of Excellence, Prof. Zainal Arifin Hasibuan, MLS., Ph.D., Director of INBISKOM and Chair of the UNIKOM Cooperative, Prof. Dr. Lilis Puspitawati, S.E., M.Si., Ak.CA., Chair of the Coop-Preneur Fest Organizing Committee, Apriani Puti Furfini, S.Kom., M.T., UNIKOM leadership, deans, program chairs, faculty members, support staff, cooperative members, and students participating in Market Day.

    The Executive Chair of the 2026 Coop-Preneur Fest, Apriani Puti Furfini, S.Kom., M.T., expressed her appreciation to the entire leadership team, invited guests, cooperative members, and students who had supported the event. She explained that this year’s UNIKOM Market Day involved 622 students divided into 260 business groups. The students showcased a variety of products that they developed and marketed directly during the event. “This year’s Market Day was attended by 622 students divided into 260 business groups. Over the course of two days, the students showcased and marketed various products they developed themselves. This event is expected to serve not only as a buying and selling activity but also as a platform for students to learn how to design products, build businesses, market products, interact with consumers, and cultivate an entrepreneurial spirit,” she said.

    In addition, she explained that the products showcased by the students included food and beverages, regional culinary specialties, creative products and handicrafts, ornamental plants, and various other innovative products. This diversity reflects the creative potential of UNIKOM students in transforming ideas into products with economic value. Apriani also encouraged the entire academic community to show appreciation for the students’ work by purchasing and using the products they have created. “Let’s support the efforts and creations of UNIKOM students so they become more confident in innovating, developing their businesses, and becoming a generation of entrepreneurs capable of contributing to UNIKOM’s progress,” she added.

    Meanwhile, the Director of INBISKOM and Chair of the UNIKOM Cooperative, Prof. Dr. Lilis Puspitawati, S.E., M.Si., Ak.CA., stated that Market Day is a form of entrepreneurship education that provides students with hands-on experience. According to her, the event serves as a platform for students not only to showcase their products but also to hone their skills in running business operations. “Alhamdulillah, today we are able to gather together to make the most of one of the most important educational opportunities for students the second UNIKOM Market Day while also celebrating the third anniversary of the UNIKOM KOSMART Cooperative. Let’s express our appreciation to everyone who has supported this event,” said Prof. Lilis.

    Prof. Lilis also noted that this year’s Market Day was attended by more than 600 students showcasing a variety of product categories. According to her, the event provided an opportunity for students to showcase their product development efforts while learning to interact directly with consumers. “This second Market Day was attended by more than 600 students showcasing a variety of product categories. The main objective is to present and introduce high-quality student products, ranging from various food items, creative industry products, handicrafts, to other products,” she explained.

    Furthermore, Prof. Lilis hopes that the experience students gained during Market Day will not end when the event concludes. Students are encouraged to continue the ventures they have started so that they can grow into sustainable businesses. “Our hope is that this activity doesn’t stop here. Students can continue their businesses until they truly become thriving industries. Not only by selling offline, but in the future they’ll also be able to leverage digital platforms so that student products can be marketed online and evolve into digital businesses,” she said. According to Prof. Lilis, the use of digital technology will provide broader opportunities for students to expand their markets. Therefore, Market Day is expected to serve as a starting point for students to continuously test, refine, and expand their businesses.

    The UNIKOM KOSMART Cooperative, she continued, is expected not only to function as a consumer cooperative but also to expand its business scope and serve as a platform for product development and business growth within the UNIKOM community. “Moving forward, we hope the products produced can become increasingly integrated with the cooperative. Currently, we are still at the consumer cooperative stage, but God willing, in the future we will continue to develop and expand the cooperative’s operations, including by supporting businesses that are growing within the UNIKOM community,” he concluded.

    In line with this, UNIKOM’s Vice Rector 4 for Digital Technology & ICT, International Programs & Center of Excellence, Prof. Zainal Arifin Hasibuan, MLS., Ph.D., noted that Market Day and the UNIKOM KOSMART Cooperative play a strategic role in fostering a culture of entrepreneurship among students. According to him, students do not necessarily have to focus on becoming employees after graduation but can also prepare themselves to create jobs through entrepreneurship. “When students and Gen Z are about to graduate, they certainly need to start planning for the future. Do they want to become civil servants, work for a company, or start their own business? We shouldn’t just think about becoming part of large corporations. We can start small and then grow into a larger business,”  said Prof. Zainal.

    Prof. Zainal explained that business development can begin on the simplest scale such as a home-based business and then grow into micro, small, and medium-sized enterprises. These stages are a crucial process for building experience and business management skills. “Don’t look down on small businesses. It is precisely through small businesses that we can gain experience and gradually grow our ventures,” he explained.

    Prof. Zainal also highlighted the importance of students’ ability to integrate hands-on business activities with the use of digital technology. In his view, physical and digital operations are not mutually exclusive but can complement one another. “In the digital age, we need not worry about the existence of physical locations. Physical and digital tenants actually complement each other. People who come in person to a place like this can experience the products firsthand, but at the same time, those products can also be marketed through digital channels. Conversely, digital activities can encourage people to come and see the products in person,” he said.

    According to him, Indonesia possesses a wealth of highly diverse products and services, including those born from the creativity of communities in various regions. This potential can become an economic strength if developed through innovation, marketing, and sound business management. “Indonesia is rich in a wide variety of products and services. At the MSME level, we have immense potential stemming from various regions, ethnic groups, cultures, and the creativity of the people. All of this has great potential to become an economic force if we are able to manage it well,” he added.

    The highlight of the ceremonial events marking the 3rd anniversary of the UNIKOM KOSMART Cooperative was the tumpeng-cutting ceremony performed by the UNIKOM Vice Rector together with the leadership team and the organizing committee. This ceremony symbolized gratitude as well as the hope that the UNIKOM KOSMART Cooperative will continue to grow as an independent and adaptive hub for innovation, capable of supporting students’ entrepreneurial creativity and the well-being of the UNIKOM academic community.

    Following the ceremony, the Vice Rector, along with the leadership team and invited guests, toured the Market Day booths created by students throughout the Smart Building lobby area. The leadership’s presence at the booths served as a gesture of appreciation and an opportunity to see firsthand the various products and business concepts developed by the students. In addition to buying and selling activities, Market Day also featured competitions for Best Booth (1st, 2nd, and 3rd place) and Highest Sales. The judging panel evaluated entries based on the creativity of the booth’s design, product quality, innovation, and the number of products sold.

    During the judging session, the panel of judges toured each booth to observe product presentations firsthand and conduct their evaluations. Out of a total of 95 participating booths on the first day, participants were given the opportunity to present their products and explain their respective business concepts. Coop-Preneur Fest continued on the second day with the 2026 P2MW Sharing Session, an entrepreneurship talk show featuring Ceptian Suryana, M.Ds., Founder and CEO of Jamise Syari who served as both a guest speaker and a UNIKOM alumnus as well as the selection of the best booths from a total of 114 booths on the second day. Through the 2026 Coop-Preneur Fest, UNIKOM not only provides a platform for students to market their products but also fosters an entrepreneurial experience integrated with learning, digital technology, and the strengthening of cooperatives. The spirit of “Creative Action, Safe Innovation” serves as a driving force, encouraging students to boldly transform creativity into products, products into businesses, and businesses into sustainable ventures. Now in its third year, UNIKOM’s Smart Cooperative (KOSMART) is expected to increasingly serve as a driving force for the entrepreneurial ecosystem on campus, while also acting as a platform for collaboration that brings together students, the academic community, cooperatives, and business actors to create economic

    Authors: Asep Bayu Dani Nandiyanto ;  Yustika Desti Yolanda;  Mia Widyaningsih ;  Risti Ragadhita ; Herry Saputra ; Eddy Soeryanto Soegoto ; Senny Luckyardi

    DOI: 10.18280/mmep.090435

    Abstract

    The purpose of this study was to examine two models of the economic feasibility of producing nanoparticle of dysprosium-doped cobalt ferrites by sol-gel auto-combustion method, from a laboratory scale to an industrial scale, including technical analysis and economic evaluation. Various economic evaluation parameters were analyzed to report the fabrication potential of dysprosium-doped cobalt ferrites nanoparticles in the case of the time required for a speculation to recover its total initial expenditure (PBP), the conditions of a generating project in the production function in years (CNPV), undertaking profits, etc. The results of the economic feasibility study on the production of dysprosium-doped cobalt ferrites nanoparticles showed that all parameter changes gave positive values, demonstrating that this project might have been practical to run commercially and on a large scale. Technical analysis to produce 26.4 tons of dysprosium-doped cobalt ferrites nanoparticles per year reveals that investment will be gainful then afterward more than three years. This project emulates PBP capital market guidelines due to the crisp return on investment. Estimates range from ideal to worstcase states in production to ensure project feasibility, including labor, sales, crude materials, utilities, external factors, and taxes. © 2022,Mathematical Modelling of Engineering Problems.

  • Implementation of Speech to Text and Geolocation Technology on the Travelling Merchant System

    Authors: Eko Budi Setiawan, Syifaul Mukminin, Angga Setiyadi, Chrismikha Hardyanto

    DOI: 10.1109/INCITEST64888.2024.11121482

    Abstract

    Travelling merchants are a type of business providing food needs in the informal sector. Currently, when consumers want to make an order, they have to type in the criteria in the form of a fairly long text. Consumers also often have difficulty detecting the location of travelling merchants in their vicinity. This research developed a responsive mobile webbased application utilizing speech recognition technology, specifically speech-to-text. The speech-to-text feature is powered by the Hugging Face Whisper API, which is applied during the food ordering process and geolocation technology in the form of Location Based Service to detect travelling merchants’ locations in real-time. The notification feature uses service workers and socket.io to provide information when a travelling merchant is nearby the buyer’s location. The software was developed using an agile methodology model. Based on the test results, 100% of all features were running well, 82.4% of travelling merchants, and 94.4% of buyers agreed that the implementation of the research results could simplify the process of ordering food and meeting between travelling merchants and buyers. © 2024 IEEE.

The method used in this research is experimental. From the client-side, this system is controlled using ESP32. Meanwhile, from the server-side, the system is supervised by the admin using a web application. The admin is tasked with verifying incoming orders via the web application and sending the barcode to the buyer’s email. ESP32 will wait for the buyer to scan the barcode on the vending machine. If it’s is valid, the ESP32 will inform the buyer via OLED. Furthermore, the ESP32 will activate the DC motor to run the conveyor. The completion of the t-shirt release process is detected using an infrared sensor. ESP32 then informs the server that the process has been completed. Modular testing is carried out to test each tool component’s function. Meanwhile, overall testing is carried out to test system functionality. Based on the results of these two tests, the Vending Machine Using ESP32 works 100% as expected. This tool can read the QR-Code input, validate data to the server, issue t-shirts according to validated orders, and request order deletion to the server when the transaction has been completed. With this tool, it is hoped that it can help sellers and make it easy for tourists. © 2023 IEEE.

  • Autonomous Cyber Physical System : Theoretical Model for Monitoring Green Tea Withering Process

    Authors: Sopian Alviana; Taufik Djatna; Shelvie Nidya Neyman; Sri Wahjuni

    Abstract

    Cyber Physical System (CPS) is a relationship between physical entities and virtual entities. CPS has a complexity in conducting relationships between three components, namely physical components, cyber components, and communication. CPS moves towards an autonomous system, so a modeling of the system is needed. Green tea withering is one of the processes in green tea processing by flowing a number of tea leaves into the withering machine. Model Based System Engineering-based modeling can be used to map the needs of autonomous CPS systems. Autonomous CPS modeling is expected to map the needs both in terms of functional, logical, and physical for autonomous CPS in the green tea withering process. This model is expected to represent the behavioral needs of the autonomous CPS system for green tea withering as a case study on autonomous CPS that moves dynamically. Therefore, the depiction of this model can provide an overview of the needs of the autonomous system in the green tea withering process. © 2023 IEEE.
