Abstract

Corn is a well-cultivated food crop that is grown extensively worldwide. The used portion of corn is its seeds, which are rich in oil. The objective of this study is to separate and characterize tocopherol from corn oil in Dompu, Sumbawa by employing spectroscopic techniques such as ultraviolet (UV) spectrophotometry, ultra-performance liquid chromatography (UPLC), nuclear magnetic resonance (NMR), and liquid chromatography-mass spectrometry (LC-MS). Subsequently, the in-vitro antioxidant activity of the tocopherol was assessed. 1 kilogram of dry maize kernels subjected to 70% ethanol extraction yielded 30 grams (35 ml) of corn oil. The purified isolate obtained from the fractionated extract, using radial chromatography, demonstrated the presence of tocopherol. The isolated sample exhibited the presence of beta-tocopherol. Beta-tocopherol's anti-aging properties were assessed by conducting an in-vitro antioxidant activity test utilizing the tyrosinase enzyme. The IC50 value obtained was 83.954±2.849 ppm. The IC50 value indicates that beta-tocopherol possesses significant antioxidant activity, making it suitable for usage as a primary ingredient in cosmetics and pharmaceutical products.

Abstract

This article discusses the development of a hydration reminder device aimed at encouraging regular water intake. Created within an Outcome-Based Education (OBE) framework in a medical instrumentation and electronics course, the prototype is designed using the ADDIE model for systematic development. The device, which has reached a Technology Readiness Level (TRL) of 3, features a user-friendly interface and gender-specific hydration metrics to improve personal health management. This interdisciplinary approach integrates educational goals with practical health benefits, anticipating the device's application in both academic settings and everyday use. Plans for intellectual property registration and academic dissemination aim to broaden the project's impact.

Abstract

The unemployment rate for vocational high school graduates is still very high. Unemployment occurs because the level of work readiness is still low. Work readiness can be improved by applying competence mastery-oriented learning. Competence that is complete requires measurement tools or assessment of student work competencies to measure competency success. Therefore, this study aims to: (1) produce a product in the form of a practical performance assessment tool for students in the conveyor-based pandemic era with android control; (2) know the quality and performance of the developed tools; This research is development research using the method of combining the waterfall method and Borg & Gall. This research focuses on product functionality so that testing is carried out by technicians with input from experts from the industry. The research data were obtained from observations, interviews, document studies, and questionnaires. The results of this study are as follows: (1) the product developed already has basic functions and can be operated using Android; (2) the results of testing by technicians from the aspects of functionality, reliability, efficiency, maintainability, and portability obtained a conformity percentage of 90% (Very Good), so that the tool can be used to test student work readiness in vocational schools or training institutions.

Abstract

This study aims to develop Electrical Machine Training Kit for electrical machine practice media in vocational education. This type of research with Analyze, Design, Development, Implementation, and Evaluation (ADDIE) model. The background of this research is that the need for electrical machine competency, which students should have mastered, is still insufficient due to inadequate tools. Many graduates still have difficulty getting a job in the industry because competence has not been fulfilled during college. Electronic engineering vocational education is a study program that has the goal of producing superior graduates in achieve electrical machine competence and being ready to work in the industry. Electronic engineering vocational education is a new study program that is still in the development stage to achieve this goal.

Abstract

Plastic waste has become a significant problem of environmental pollution in recent decades. The nature of plastic waste is complicated to decompose; it has worsened the environmental situation, especially if it is not taken seriously immediately. One approach that can be taken to overcome this problem is to provide counseling to the public so that they do not dispose of plastic waste carelessly. The community service program is a forum for academics to participate and provide counseling about the management of plastic waste. The purpose of this community service program is to counsel the Panjangrejo community about how to manage plastic waste properly. This counseling program began with discussions with the Panjangrejo sub-district officials and related parties, then continued with planning the timing of the extension. Residents and community elements are fully involved, so this program can run smoothly. The counseling program was carried out in three villages, namely the villages of Semampir, Gunung Puyuh, and Krapyak Wetan, and this program was held at night from 20.00 WIB to 22.00 WIB. The outreach results showed that people's knowledge about the dangers of plastic waste and how to manage it could be significantly improved (p < 0.05). In general, this extension program successfully increased respondents' knowledge from "not knowing" to "knowing better" about the dangers and how to manage plastic waste.
