Lingqun Zuo — 2024-07-04

Background: Faced with the new demand for logistics engineering talents in the modern logistics industry's mathematical transformation and upgrading, building an applied logistics engineering talent training system that meets the requirements of the new era is a key task of current teaching reform.

Contribution: The contribution of this experiment is focuses on the current situation of school enterprise integration in school logistics engineering construction, and proposes a construction.

Method: This experiment using framework method to strengthen the logistics engineering profession, clarify integration goals, build targeted curriculum systems, establish assessment and evaluation frameworks, and improve the mechanism of industry education integration.

Results: The collaborative educational role of logistics professional construction and innovation and entrepreneurship education and cultivate more comprehensive logistics professionals. Based on this, this article will conduct a digital system for logistics majors from the perspective of smart education in vocational colleges under the background of intelligent logistics.

Conclusion: Curriculum construction is built on a dynamic and authentic practical process, which reflects the logical interaction between curriculum builders and courses, shifting understanding from project logic to subjective logic

Innovative Internet of Things-based Integrated Liquid Waste Monitoring for Sustainable Batik Industry

Muhammad Fatih Qodri — 2024-07-04

Background: Batik, a UNESCO-recognized art form, experiences rising production demands. However, traditional waste disposal methods pollute waterways and degrade soil. This study addresses this concern.

Contribution: We implemented an Internet of Things (IoT)-based liquid waste monitoring system in CV Smart Batik Indonesia to promote a green economy and sustainable practices. The system monitors critical waste parameters (temperature, pH, TDS, DO, turbidity) in real-time.

Method: We integrated sensors to collect waste data, which is then transmitted through an internet network for monitoring.

Results: The system offers automated monitoring with notifications via a website or mobile application while ensuring data confidentiality through Wireguard protection.

Conclusion: This community service activity demonstrates the effectiveness of IoT-based monitoring systems in promoting sustainable batik production by ensuring compliance with environmental standards and reducing human workload in waste monitoring

Empowering Communities with Integrated Pest Management for Sustainable Agriculture

Muhammad Reza Aulia — 2024-07-04

Background: The aim of this community development initiative, centered around community engagement, is to address the pressing issue of declining agricultural productivity due to pest infestations in the Asahan Regency, a developing area. Through educational and training programs, the initiative seeks to advocate for Integrated Pest Management (IPM) practices and safe pesticide usage among farmers, while also addressing the environmental impacts of chemical pesticide use.

Contribution: The primary focus is to gauge the impact of these initiatives in fostering sustainable and environmentally responsible agricultural practices in Asahan Regency, ultimately enhancing the overall well-being of the farming community.

Method: A total of 50 farmers actively participated in these programs, all of whom derived substantial benefits that directly contributed to the improvement of their livelihoods.

Results: The implementation of IPM with a community development approach has the potential to significantly enhance paddy rice productivity while promoting sustainable agriculture

Conclusion: By involving the local community, improving pest control methods, reducing environmental impact, and fostering knowledge sharing, this approach can lead to positive outcomes for both farmers and the environment

Experiment Evaluation on the Porosity of Plasma Coating from Ceramic Al2O3 – TiO2 Using the Metallography

duong vu — 2024-07-04

Background: The objective of this paper is an experimental investigation of the metallographic porosity of plasma coating using standard materials from the ceramic system Al₂O₃-TiO₂ on the substrate of steel SS400 at laboratory scale Lab at the Research Institute of Mechanical Engineering.

Contribution: The main contribution of the research is the evaluation of the porosity of the coating under the influence of the main technological parameters since the porosity plays a significant role in the performance of the working surface using the built-in Image Pro-Analyzer software in the Axiovert 25 MAT microscope.

Method: The spraying material is Al₂O₃-TiO₂ powder. The input parameters are: spraying distance (Lp; current of plasma stream (Ip); powder feed flow (Gp and spraying rate (Vp).

Results: The findings show that the average porosity of the Al₂O₃-TiO₂ plasma coating is inversely decreasing in the increasing direction of the distance: spray in the range Lp = 100–200 mm, increase proportional to the increase of the current plasma flow rate in the range Ip = 400–600 A, provided that the powder feed flow Gp = 1.7 kg/h and the spraying rate Vp = 50 mm/min.

Conclusion: The degree of influence of the three main technological parameters (Lp, Ip, and Gp) in the survey limit domain may be due to the selected Lp spray distance within the relatively wide recommended range of the plasma spraying equipment supplier. It is recommended to conduct the experimental planning of the L27 type to localize the optimum area.

Development of Indonesian Association of People with Disabilities (PPDI) Volunteers Based on Digital Applications to Increase Deaf Interaction

Sigit Hardiyanto — 2024-07-04

Background: Effective communication is essential for everyone, but it can be especially difficult for those who are deaf or hard of hearing. This can lead to isolation and hinder their ability to express themselves. Unfortunately, many people, including volunteers from PPDI North Sumatra, lack sign language skills, creating a communication barrier with the deaf community.

Contribution: This activity aims to develop and assist Regional Representative Council PPDI North Sumatra volunteers to increase interaction with the deaf at Regional Representative Council PPDI North Sumatra

Method: PPDI volunteers participated in program socialization, learned PIKU application features, and received training on its use.

Results: The PIKU program yielded positive outcomes. Volunteer participation was enthusiastic, and interaction with the deaf community increased. The app's free accessibility, user-friendly interface, and clear visuals facilitated communication.

Conclusion: The PIKU program, with its communication-assistive technology, effectively improved interaction between PPDI volunteers and the deaf community in North Sumatra. This highlights the potential of technology to break down communication barriers and foster inclusivity

Application of Geographic Information System (GIS) Technology to Formulate Unused Spring Water Optimization Strategy

Ahmad Rifan Khoirul Lisan — 2024-07-04

Background: This article presents the findings of a comprehensive community empowerment program that focused on the application of Geographic Information System (GIS) technology for the optimization strategy formulation of unused spring water.

Contribution: The contribution of this program address the challenge for better utilization of unused spring water and promote sustainable water management practices.

Method: The study employed GIS technology to identify and map unused springs, followed by hydrological analysis and water quality assessment to inform the development of optimization strategies.

Results: This program suggested infrastructure development, water conservation measures, and distribution network design to enhance water availability.

Conclusion: The findings show that GIS approach is suitable for further applications in other Indonesian mountainous villages with similarly shared community traits. However, further some locality aspects, including, but not limited to community leadership and economic power, need to be assessed further, as they play significant influences on the success of the program
