Abstract

Electric vehicles are emerging as a key trend in sustainable mobility, mitigating emissions, and reducing dependence on fossil fuels. The challenge in optimizing route modeling lies in some limitations, such as battery range, charging time, and the diversity of electric vehicle types. This article explores the optimality of routes in a multiple-trip distribution system using a heterogeneous fleet of electric vehicles. The electric vehicle routing problem is formulated as a mixed-integer linear programming aiming to find the most cost-efficient optimal route. A notable feature of the model allows electric vehicle fleets to undertake additional travel to complete distribution tasks, i.e., multiple trips. The model is implemented in two illustrative examples involving the delivery of goods using homogeneous and heterogeneous electric vehicle fleets characterized by loading and battery capacities. Each case includes one depot, 8 and 10 customers, and 2 battery swapping stations, solved using the branch-and-bound method through Lingo 18.0. Simulation results indicate that battery capacity and the presence of battery swapping stations significantly influence the routes selection.

Abstract

Community service is a form of movement in making a real contribution to society which aims to provide solutions to real problems that occur in society. Most of the Indonesian population still relies on the agriculture, plantation and livestock sectors to drive the economy. By-products in the form of waste are generally used as fertilizer which can actually be used as an alternative energy source. Biogas is a renewable energy produced through the process of anaerobic digestion of organic materials which is currently widely used by the community as an alternative energy to replace LPG for cooking and generator fuel to produce electricity. One of the utilization of non-hazardous biomass waste into energy in the form of biogas has been implemented in Tadukan Raga village in Sinembah Tanjung Muda (STM) Hilir District, Deli Serdang Regency which has been operated since 2018 and is equipped with a barn for mushroom cultivation. However, problems arise where the facility is abandoned where there is a lack of maintenance of biogas generation facilities and mushroom barns, lack of human resources and low understanding of the community, especially BUMDes in the management, development and business maintenance of this facility. Therefore, it is necessary to provide counseling and training to the community in the operation of biogas facilities, revitalize mushroom barns in biomass non-b3 waste utilization facilities and modify LPG stoves into biogas stoves and install stoves in residents' homes around Tungkusan hamlet. Tadukan Raga Village itself is a fostered village that has been used as a place for counseling and service from the University of North Sumatra to the community because there are still several things that need to be improved, so counseling is again carried out in this village.

Abstract

Penelitian ini bertujuan untuk menggambarkan profil dan perbedaan kesadaran multikultural generasi Z yang direpresentasikan oleh mahasiswa UNY. Penelitian ini menggunakan pendekatan deskriptif dengan menggabungkan metode kuantitatif dan kualitatif (metode campuran). Populasi penelitian adalah mahasiswa Universitas Negeri Yogyakarta sejumlah 29.983 mahasiswa dengan pengambilan sampel secara acak multistage random sampling. Pelaksanaannya dilakukan dengan membagi populasi menjadi dua bagian, yaitu kelompok mahasiswa eksakta dan mahasiswa sosial-humaniora kemudian diambil sampelnya. Teknik penarikan sampel menggunakan rumus Lemeshow diperoleh sampel sebesar 95,73. Untuk menghindari adanya respon yang droup out maka jumlah sampel dibulatkan menjadi 200 orang untuk masing-masing kelompok mahasiswa eksakta dan mahasiswa sosial-humaniora dengan total 400 mahasiswa untuk kedua kelompok. Teknik pengumpulan data menggunakan kuesioner yang diadopsi dari kuesioner yang dikembangkan oleh Tim Zamroni dan kawan-kawan. Analisis data penelitian ini menggunakan teknik analisis data kuantitatif dengan statistik uji-t. Hasil penelitian menunjukkan bahwa terdapat perbedaan kesadaran multikultural mahasiswa berdasarkan latar belakang keilmuan, yaitu mahasiswa dari fakultas sosial humaniora dan mahasiswa dari fakultas sains. Perbedaan ini menunjukkan bahwa latar belakang sosial budaya berimplikasi pada perbedaan kesadaran budaya. Diperlukan program yang holistik untuk memperkuat kesadaran multikultural di kalangan generasi Z. The purpose of this research was to describe the profile of multicultural awareness of the students' of Yogyakarta State University (UNY). This study used a descriptive approach by combining quantitative and qualitative methods (mix methods). The quantitative approach is used as the main method and the qualitative approach as the secondary method. The research population was students of Yogyakarta State University with a total of 29983 people. Multistage random sampling was conducted by dividing the population into two parts, namely groups of exact science students and social-humanities students, then the samples were taken. The sampling technique using the Lemeshow formula, obtained a sample of  95.73. To avoid a dropout of responses, the number of samples was rounded up to 200 people for each group of exact science students and social-humanities students with a total of 400 students for both groups. The data collection technique used a questionnaire which was adopted from the questionnaire developed by Tim Zamroni et al. Data analysis was quantitative analysis using T-test statistics. The results indicate that there are differences of the students'multicultural awareness based on scientific backgrounds, such as social humanities and science. This difference shows that scientific backgrounds can form different multicultural awareness. Socio-cultural background influences multicultural experiences in cultural communication and adaptation in social interactions. A holistic program is requiered to strengthen multi-cultural awareness among generation Z.

Abstract

This study aimed to describe the tradition of character building in maritime shipping. The source of the data was the result of ethnographic studies on the sailor community on Binongko Island, Wakatobi Regency. The main instrument in research was researchers, data collection was done through in-depth interviews, participant observation, and document analysis. The results of the study indicated that in the maritime shipping of sailors Binongko-Wakatobi is known for four stages of the character building tradition, namely; (1) providing moral knowledge through prospective sailors; (2) moral inspiration through the role of a koki, (3) moral actions played by sawi; and (4) role models played by juragan. The four stages were interrelated cycles that showed the value of the character's urgency both in maritime shipping. In addition, it is known that the typical character of Binongko sailors who are generally tough, patient, hardworking, unyielding, honest, simple, responsible, and friendly to nature, were formed through the tradition of maritime shipping. Character building interactions occur in oceanic spaces, a means of character building is a traditional boat, while the learning media are marine objects such as; waves, wind and coral.

Abstract

Travelling Salesman Problem (TSP) is a problem where a person must visit some places, starting from one city and then moving on to the next city with the conditions that the places visited can only be passed precisely once and then back to the starting city. TSP is an NP-hard, an important problem in operations research. TSP problems can be solved by an exact method or an approximation method, namely the metaheuristic method. This research aims to solve the TSP problem with an approximation method called the Simulated Annealing (SA), and then compare the results of this approximation method with the exact Branch and Bound method. The results indicated that the SA method could accomplish TSP problems. However, like other metaheuristic methods, SA only accomplishes it using an approach to get good results. Still, it cannot be determined that SA has the most optimal results, but the time needed by the SA method is faster than the Branch and Bound method. In case I, the percentage difference between the distance generated using the SA method with the B-and-B method is 0%, in case II it is 7% and in case III it is 8%.

Abstract

Unsold vegetable waste from agricultural products generally rots and ends up in landfills, increasing waste volume and creating environmental problems. Utilizing vegetable waste as a raw material for bioethanol is a potential alternative, considering that bioethanol is a renewable energy source that can be produced through a biomass fermentation process. This study designed a 15 liter bioethanol production unit utilizing various types of vegetable waste, such as potatoes, pineapples, carrots, mustard greens, and cabbage. The process unit consists of pre-treatment equipment (a pre-cooking tank, a crusher, and a pressure tank), a fermenter equipped with two 30 cm diameter paddle-type manual stirrers, and a stainless steel distillation unit equipped with a heater and cooling tank. The fermentation process lasts for 48–72 hours and produces bioethanol with a concentration of 45%. This program is expected to provide dual benefits: as a solution for vegetable waste management to reduce environmental impacts and as a source of additional income for the community through the utilization of the bioethanol produced.

Abstract

Bullying poses a serious threat to adolescent mental health, yet prevention campaigns in schools are often hampered by teachers' limited ability to produce relevant digital educational content. This community service program aims to enhance the competence of Junior High School (SMP) teachers in Kulon Progo in designing contextual anti-bullying digital content. This initiative is a downstream implementation of the "Anti-Bully Digital Channel" research, offering social innovation engineering for character education. The methodology included participatory training, content creation practice, action plan development, and technical mentoring. Evaluation results demonstrated significant impact across four aspects: a 25.3% increase in conceptual understanding of bullying, 80% of participants successfully producing publication-ready digital content, a 37% rise in teacher confidence in handling bullying cases, and an 82% commitment from teachers to integrate digital campaigns into the school ecosystem. This program proves that enhancing teacher digital literacy is an effective strategy for creating a safe school climate responsive to digital era challenges.
