Abstract

The usage of advertising as a medium for marketing products/services is used by various businesses to increase profits. The advertising medium mainly used is billboards, which still use fossil energy as an energy source. The Indonesian government's 2060 Net Zero Emission Program promotes using renewable energy (RE) as an energy source, such as photovoltaic (PV) as electrical energy from solar heat. As with RE, the development of PV still has problems in products and business, but PV is ready to be used as an energy source to reduce electricity bill costs. The business idea of PV installation in the advertising company sector emerged to support the government program Net Zero Emission, making advertising companies "green jobs" and absorbing human resources from vocational schools. Business conceptual design with value chains, business model canvas, and lean canvas expected can provide an overview of business opportunities with EBT for Indonesia that are environmentally friendly and energy independent.

Abstract

High-stress levels can trigger other diseases if emotions are not channeled to reduce the feeling of stress. The stress-releasing activity that is currently trending is keeping animals, especially cats and dogs. Having a pet triggers awareness of the importance of pet care, especially in the context of home visiting services, highlighting the need for increased effectiveness of veterinary services. Determining a short route for veterinarians to visit their patients in a certain area is necessary in planning for pet clinics with home visit services. In the context of home visits by pet clinics, the Traveling Salesman Problem (TSP) is used to determine the most efficient route veterinarians can use when visiting many patients in a certain area by minimizing the total distance traveled to save time. This research uses the Particle Swarm Optimization (PSO) algorithm with 2-opt logic to solve the TSP problem. This TSP optimization was completed by utilizing Google Colab as a machine learning computing medium using Python. The results of optimizing the total distance for the best routes of home visits to pet clinics was 292.81 kilometers. This research can still be developed for more complex routes and have requirements for each route destination, such as visiting time for each patient and distance between destination points. The research is expected to impact the welfare of pets and meet community needs positively.

Abstract

The batik industry, as part of Indonesia’s cultural heritage, faces significant challenges in the digital era and Industry 4.0. This study analyzes the stages of ERP-based digital transformation in batik SMEs through a case study at Batik Paradise Yogyakarta, designated by the Ministry of Industry as a pilot project in 2024. Using a qualitative descriptive approach with observations, semi-structured interviews, and documentation, the research identifies four implementation phases: (1) preparation and needs analysis, (2) core module implementation, (3) cross-functional integration, and (4) optimization and evaluation. Findings show that ERP adoption enhances operational efficiency, financial transparency, and data integration while supporting cultural preservation through motif and production documentation. The study contributes an adaptive ERP implementation model for batik SMEs and offers policy recommendations to strengthen digital competitiveness.

Abstract

Pendidikan vokasi berperan strategis dalam menyiapkan tenaga kerja terampil yang mampu menjawab kebutuhan industri modern, namun kualitas layanan masih menghadapi tantangan pada aspek Tangible. Penelitian ini bertujuan menganalisis dan merumuskan strategi peningkatan mutu layanan pendidikan vokasi pada dimensi Tangible di Perguruan Tinggi Tekstil XYZ. Perumusan menggunakan pendekatan studi kasus, data dikumpulkan melalui observasi, wawancara, dan kajian dokumen. Hasil dianalisis secara kualitatif dan kuantitatif menggunakan metode USG untuk menentukan prioritas permasalahan, serta TRIZ untuk menghasilkan solusi inovatif. Hasil penelitian mengidentifikasi empat isu utama yang memengaruhi mutu layanan, yaitu ketiadaan mesin Blowing untuk praktik pemintalan, tidak terdapat sistem reorder point  bahan baku sliver, sistem penilaian magang manual, serta ketiadaan standar preventive maintenance. Berdasarkan analisis USG, isu ketiadaan mesin Blowing memiliki tingkat urgensi tertinggi. Penerapan TRIZ menampilkan solusi kreatif berupa simulasi CAD 3D sebagai alternatif pembelajaran praktik dan pengembangan kalkulator ROP berbasis HTML dengan dukungan kecerdasan buatan untuk pengelolaan bahan praktik. Temuan ini menegaskan bahwa penerapan inovasi teknologi dan digitalisasi proses pembelajaran tidak hanya mampu menutup keterbatasan sarana fisik, tetapi juga mendorong efisiensi operasional serta memperkuat keterhubungan antara proses pendidikan vokasi dan kebutuhan industri. Hasil penelitian ini berimplikasi pada perlunya transformasi manajemen fasilitas pembelajaran menuju model layanan vokasi adaptif, inovatif, dan berorientasi industri.
