The high demand for plastic use today will result in environmental damage because the plastic that is widely used cannot be broken down. This plastic waste is dangerous for the sustainability of the food chain, pollutes water and soil, causes global warming, and causes air pollution. This research synthesizes a cellulose nanofiber composite with commercial starch in a 1:1 ratio with the influence of the addition of smoke liquid from palm oil waste. This research aims to process cellulose nanocomposite fibers combined with commercial starch and use them in biodegradable plastic by testing the effect of giving smoke liquid on the development of microbial substances in environmentally friendly biodegradable plastic food packaging. So the resulting product is expected to have the potential to reduce dependence on the use of synthetic plastic. This research aims to determine the optimum concentration of liquid acid from empty oil palm fruit bunches as an antimicrobial agent in the resulting bioplastic. The addition of liquid smoke changes the bioplastic properties of FTIR and XRD the attractive strength of bioplastic. The sample with the highest concentration of liquid smoke had the greatest tensile strength (2.34 MPa). The addition of liquid smoke concentration from empty oil palm shells showed a good inhibitory area for the development of bacillus cereus (10.8 mm).

The existence of learning media on various platforms provides variety and assistance for teachers in delivering learning materials. Not much has been developed in educational media compared to entertainment media such as gaming, films, songs, dance, and music. Educational media need to be packaged in a simple, effective, and efficient manner and respond to the needs of today’s students. In the context of the world of learning English at the junior high school level, learning media is needed as an effort to provide real experience in terms of honing English communication skills. Augmented Reality is one of the media that is able to bridge the needs of students, namely making abstract learning experiences feel concrete. Therefore, this research aims to design learning media for junior high school English on the basis of Augmented Reality with content containing stories from North Sumatra. The research method applied in this study is Research & Development. Data acquisition techniques used were documentation, questionnaires, interviews, and tests which were applied in accordance with nine research stages, namely: (1) identification and analysis of media needs; (2) collection of media materials and tools; (3) development of media prototype designs; (4) implementation media prototype; (5) media prototype validation; (6) media prototype revision; (7) media trial on junior high school students; (8) final revision; and (9) media prototype that has been tested. The final result of this study contains AR in the form of flash cards. AR markers are printed on cards and students only focus their smartphone cameras on markers that have been printed in card form. After the camera has successfully scanned the marker, a learning video will appear. There are five cards (markers) in this study, and each card will play a different learning video.

In recent years, edible films are on the rise as they have a wide variety of advantages, including the use of edible packaging materials over synthetic films. Edible films are environmentally friendly and do not cause environmental pollution. Several researchers have conducted studies on materials for making edible wraps, one of which comes from cellulosic sources. One source of cellulose from food is nata de coco. In this research, edible films based on nata de coco and chitosan were made by mixing and molding methods. The results of the tensile strength test of samples with a variety of 20 mL acetic acid showed a value of 17.805 MPa. This value meets the bioplastic standard (10–100 MPa) and the Indonesian National Standard (SNI) for conventional plastic (24–302 MPa).

Agricultural extension workers play an essential role in increasing shallot yields. They provide technical counseling, transfer knowledge and skills, and are involved in post-harvest monitoring, mentoring, and counseling. In addition, they also provide information about business development and marketing. Agricultural extension interpersonal communication competence plays a crucial role in efforts to increase shallot yields in Enrekang. With these competencies, agricultural extension agents can establish good relationships with farmers, understand their needs, and communicate effectively to transfer relevant knowledge and skills. Through effective interpersonal communication, agricultural extension workers can assist farmers in implementing proper cultivation practices, overcoming obstacles, providing motivation, and building collaboration between farmers and related parties. This article uses a qualitative descriptive methodology. The result showed that the agricultural extension interpersonal communication competence is outstanding and has a positive value for farmers in Enrekang Regency. Some farmers are still reluctant and indifferent to following directions from extension agents because they consider themselves quite experienced in farming.

Historically, the exploration of corrosion inhibitor technology has relied extensively on experimental methodologies, which are inherently associated with substantial costs, prolonged durations, and significant resource utilization. However, the emergence of ML approaches has recently garnered attention as a promising avenue for investigating potential materials with corrosion inhibition properties. This study endeavors to enhance the predictive capacity of ML models by leveraging polynomial functions. Specifically, the investigation focuses on assessing the effectiveness of pyridinequinoline compounds in mitigating corrosion. Diverse ML models were systematically evaluated, integrating polynomial functions to augment their predictive capabilities. The integration of polynomial functions notably amplifies the predictive accuracy across all tested models. Notably, the SVR model emerges as the most adept, exhibiting R² of 0.936 and RMSE of 0.093. The outcomes of this inquiry underscore a significant enhancement in predictive accuracy facilitated by the incorporation of polynomial functions within ML models. The proposed SVR model stands out as a robust tool for prognosticating the corrosion inhibition potential of pyridine-quinoline compounds. This pioneering approach contributes invaluable insights into advancing machine learning methodologies geared toward designing and engineering materials with promising corrosion inhibition properties.

Abstract. Microgreens, the young seedlings of edible plants, have gained attention for their potential health benefits and culinary applications. This newly emerging functional food crop has the potential to sustainably diversify global food systems, facilitate urbanization and climate change responses, and advance human health. However, their reception among school students remains an understudied area, particularly in the Malaysian context. In this study, five microgreens species including ulam raja, red amaranth, red radish, daikon, and corn were evaluated for their sensory perception and acceptability among secondary school students in Selangor, and their phytochemical compositions. Among the evaluated species, corn exhibited the highest intensity of sweetness, ulam raja demonstrated a strong aroma and bitterness, while red radish was notable for its astringency and heat. Red amaranth had the highest intensity of grassy taste, and all five microgreens had a low score for sourness. Corn had the highest rating on acceptability of flavor and overall eating quality, signifying its favorable impression among students. Conversely, red radish and ulam raja received the lowest acceptability scores in both categories. The highest total phenolic and flavonoid content and antioxidant activity was exhibited in ulam raja. These findings suggest the potential to leverage corn’s favorable acceptability to introduce microgreens into student diets. In general, this study highlights the correlation between sensory attributes and phytochemical composition, both influencing the Malaysian students’ perceptions of microgreens. By understanding their preferences, educators, policymakers, and entrepreneurs can formulate effective strategies for healthier eating habits among the youth and develop successful commercialization strategies. Keywords: flavor, food systems, healthy diet, microgreens, student acceptance
摘要。微型蔬菜是可食用植物的幼苗，因其潜在的健康益处和烹饪应用而备受关注。这种新兴的功能性粮食作物有可能使全球粮食系统可持续地多样化，促进城市化和应对气候变化，并增进人类健康。然而，学生对它们的接受程度仍然是一个研究不足的领域，尤其是在马来西亚。本研究评估了雪兰莪州中学生对五种微型蔬菜（包括乌兰拉雅、红苋菜、红萝卜、萝卜和玉米）的感官感受和接受程度，以及它们的植物化学成分。在接受评估的品种中，玉米的甜度最高，乌兰拉贾有强烈的香味和苦味，而红萝卜则有明显的涩味和热味。红苋菜的青草味最重，所有五种微型蔬菜的酸味得分都很低。玉米在味道的可接受性和整体食用质量方面得分最高，这表明玉米在学生心目中印象良好。相反，红萝卜和 ulam raja 在这两个类别中的可接受性得分最低。总酚类和类黄酮含量以及抗氧化活性最高的是ulam raja。这些研究结果表明，可以利用玉米的良好可接受性将微型蔬菜引入学生饮食。总之，这项研究强调了感官属性和植物化学成分之间的相关性，两者都会影响马来西亚学生对微绿菜的看法。通过了解他们的喜好，教育工作者、政策制定者和企业家可以制定有效的策略，让年轻人养成更健康的饮食习惯，并制定成功的商业化战略。关键词：风味、食品系统、健康饮食、微绿菜、学生接受度
