Abstract

Purpose: To analyze the determining factors influencing Indonesian consumers’ interest in using paper-based food packaging. In the context of increasing plastic waste and rising environmental concerns, the study seeks to evaluate behavioral tendencies supporting sustainable consumer practices aligned with sustainable goals. Methodology: A quantitative approach using an online questionnaire with a purposive sample of 710 respondents across Indonesia. The data were analyzed using IBM SPSS and Artificial Neural Network (ANN) models to explore complex relationships between sustainable consumer behavior (SCB) variable with attitude (AT), environmental insight (EI), environmental risk perception (ERP), governmental support & regulations (GSR), intention (IN), perceived behavioral control (PBC), and subjective norm (SN). Results: The survey results processed with ANN showed a high level of accuracy for all hypothesized relationships, with AT emerging as the most influential factor on SCB (97.75% accuracy), followed by PBC and IN. All seven tested hypotheses were positively accepted. Findings: Consumers’ positive attitudes significantly influence their sustainable consumption choices in the context of preference for paper packaging over plastic packaging, indicating a shift towards environmentally responsible behavior. Novelty: This study uniquely integrates ANN into behavioral research on sustainability, offering a more precise modeling of consumer intentions and patterns compared to traditional statistical methods. Originality: Unlike previous studies focused on general consumer habits, this research considers packaging material choices to present a comprehensive model of sustainable behavior in a developing country context, emphasizing behavioral modeling over object detection or vision-based methods. Conclusion: This study underscores the need to promote positive attitudes and awareness of negative environmental impacts when using plastic packaging to encourage sustainable consumer behavior. Paper packaging can be alternative strategies to reduce plastic waste. Type of Paper: Empirical research paper.

Abstract

The implementation of OSH in the workplace is a necessity for companies or institutions that brings great benefits to all workers and is not felt as a burdensome burden but rather awareness of workers from the risk of materials. Indonesia still has a low level of work safety when compared to developed countries, this makes the risk and level of work accidents in Indonesia still high. This study aims to find solutions to the problems that hinder the application of OHS in mechanical engineering practice. This study uses a qualitative approach to describe the application of occupational safety and health in the mechanical engineering workshop, descriptive methods used in this study, in the form of interviews, observations, and documentation to collect the necessary data.  SMK Negeri 2 Pengasih has included K3 planning as a guideline for implementing practical learning in the workshop. Teacher supervision and guidance in its application is quite good regarding the work to be done. However, OHS evaluation has not been fully conducted in practical learning at school. This is related to policy and improvement of evaluation development as a basis for implementing further learning. From the evaluation, shortcomings can be identified so that better planning can be made for workshop practice for students of SMK N 2 Pengasih.

Abstract

Learning media is very necessary in the learning process in vocational high schools. The development and use of e-modules is one effort to increase students' understanding of lessons. This research used experimental methods and was conducted at Alkhairaat Bahodopi Vocational High School in the 2023/2024 academic year. The sample selection was class XI TP 1 with 10 students as the control class and class XI TP 2 with 10 students as the experimental class. The design of this research is Pretest-Posttest Control Group Design. The research instrument is student learning outcomes. Hypothesis testing uses the paired sample t-test. The analysis was carried out descriptively. The research results show that the use of E-Modules affects increasing student learning achievement compared to learning without E-Modules. This is proven by the sig value < 0.001 for both knowledge and skills values in the experimental class, which shows that the sig value is smaller than α = 0.05, so H0 is rejected and Ha is accepted. The implementation of learning with Autodesk Inventor e-modules in class XI TP 2 made a positive contribution in improving students' academic achievement, especially when compared to the usual learning in the classroom.

Abstract

In the fabrication construction course held at the Fabrication Lab, Mechanical Engineering, Yogyakarta State University, it is necessary to provide workpieces in the form of metal pipe with sizes Ø 4“ to Ø 10". In cutting activity, metal pipe can shift or rotate, so that it is very dangerous for operator who conduct the cutting activity, especially if the pipe cutting activity is conducted using a grinding machine. Due to the condition of a round grinding stone and a cylindrical iron pipe, the case will run the risk of making the grinding machine or iron pipe slip. The use of saw is also less effective and less efficient due to it requires a lot of effort and time [1]. Based on the problems, researchers created the Horizontal Gas Cutting Machine as a tool for cutting iron pipe. The research method in the manufacture of machine used Research and Development (RD) method. The machine project is conducted in five steps, such as needs analysis step, design, implementation, testing and maintenance. Working drawings on the machine design using Autodesk Inventor application. Production process on the machine includes making frames, casing, pipe support, assembling and painting. The result achieved is the creation of a horizontal gas cutting machine for cutting metal pipes that is able to cut pipes quickly, produces even pipe pieces, has brander features and is easy to operate

Abstract

Waste cooking oil or used cooking oil is potentially carcinogenic waste and dangerous to human health if used for cooking repeatedly. If waste cooking oil is disposed of in the environment, it can harm soil structure by impeding water movement in soil pores. Therefore, the development of waste cooking oil stove technology designed using the French method can be a solution to utilize waste cooking oil as an alternative fuel. The results of this research are a stove design and device that can use used cooking oil. This stove uses abundant waste cooking oil with efficient and clean combustion results through the use of FFEAS Technology. This stove uses a floating wick and an excess air system which makes the combustion process easier. The performance of the stove being developed can be seen in several tests such as ignition combustion duration, required pressure, operational time, fuel consumption rate, sensible heat, and latent heat. The results of three tests that have been conducted show that the average ignition duration of the stove is 12 minutes, the optimal pressure is 4-5 bar, the fuel consumption rate is 8.34ml/minute, the average latent heat is 1,095.82 watts, and the average sensible heat is 132.48 watts.
