Abstract

Plastic waste is one of the wastes generated from human activities and is classified as inorganic waste. Inorganic waste is difficult or cannot be decomposed, especially if the plastic is made of non-biodegradable materials. The increase in plastic waste is one of the problems faced by all parties and can threaten environmental sustainability. Efforts that can be made to minimize plastic waste are to recycle plastic waste into valuable products, such as planting media. The purpose of this community service activity is to manage plastic waste into planting media. This aims to minimize environmental pollution due to plastic waste, especially plastics that are classified as non-biodegradable. The methods used in this activity are lectures and demonstrations. The activity was attended by 37 people consisting of village officials, PKK mothers, and Karang Taurna of Blimbing Village, Kediri Regency. In this PKM activity, the participants seemed enthusiastic about participating in a series of activities from waste management education and also demonstrations in making planting media. In this activity, it is known that there is an increase in participants' knowledge about good waste management. As a follow-up effort, similar and relevant activities are needed so that public knowledge and awareness of the importance of good and correct waste management will increase, so as to create a healthy and sustainable environment.

Abstract

Generative artificial intelligence (GenAI) technology is currently receiving special attention and has numerous benefits. In the education field, this technology can help obtain information quickly to complete a thesis. This research aims to conduct GenAI Modeling based on the Technology Accepted Model (TAM) and Expected Value Theory (EVT) framework using the Partial Least Square Structural Equation Model (PLS-SEM). The research used primary data obtained from surveys. The population was all Tarbiyah faculty students who took a thesis in the Even Semester of the 2023/2024 academic year with a total of 1266. The sample in this research was 191 students who were completing their thesis and had used Gen AI technology to help complete their thesis. The sampling technique used cluster random sampling with a procedure of dividing students into 8 clusters based on the study program. The research instrument used a questionnaire consisting of 5 latent variables: Perceived Usefulness, Perceived Ease of Use, Intrinsic Motivation, Perceived Value, and Behavioral Intention to Use. The results of the analysis using the PLS-SEM method showed that Intrinsic Motivation has a significant relationship with Perceived Ease of Use, and Intrinsic Perceived Usefulness and Perceived Value have a significant relationship with Behavioral Intention to Use. These results show that students choose GenAI Technology to help complete their thesis based on its benefits, such as making it easier to prepare backgrounds, research instruments, and data analysis steps, as well as providing insight into knowledge related to the topic being researched. The research results imply the need for policies regarding the use of GenAI technology for theses so that students are wiser in using GenAI technology.

Abstract

The Online Public Access Catalog (OPAC) is a digital system that enables users to search for library references through an online interface using keywords. OPAC has been implemented to enhance IAIN Kediri library services. However, its usage has never been evaluated, resulting in limited understanding of user acceptance levels. This study aims to predict the acceptance of OPAC and identify the most influential variables using interpretable ensemble learning methods. This research used cross sectional design with data collected via a survey involving 400 IAIN Kediri students who had experience using the OPAC system. The study integrates the Technology Acceptance Model (TAM) with the Value-Based Adoption Model (VAM) framework. Predictor variables consist of Perceived Usefulness, Perceived Ease of Use, Intention, Technicality, and Enjoyment. The target variable was Actual Use. The measurement scale uses a Likert scale of 1 to 5. The instrument has been tested for validity and reliability. Ensemble learning algorithms used include Random Forest, AdaBoost, XGBoost, Lightgbm, and Catboost, with SHAP applied for model interpretability. Among the models tested, XGBoost achieved the highest predictive accuracy. SHAP analysis revealed that Enjoyment was the most significant factor influencing OPAC acceptance. These results demonstrate the effectiveness of interpretable ensemble models in predicting technology acceptance and suggest their potential as an alternative to data analysis methods. OPAC development can be done by improving the user interface and developing applications on Android.

Abstract

Background: The low level of public understanding about tuberculosis (21.9%) and the limited implementation of home ventilation as a preventive measure (31.3%) prompted the launch of the “SEHATI LESTARI” program, which focuses on strengthening health cadres to create a tuberculosis-free community. Objective: This activity aimed to increase community knowledge about TB prevention, promote the adoption of healthy behaviors, and empower health cadres as agents of change at the community level. Method: The program, conducted from 16 September to 15 October 2024 with 32 participants in Tunge Village, combined interactive lectures, simulations, and field audits to ensure a comprehensive understanding. Results: Post-activity evaluations demonstrated significant improvements: participants’ knowledge of TB increased from 21.9% to 71.9%, the adoption of home ventilation practices rose from 31.3% to 68.8%, and 32 trained health cadres were successfully established. Conclusion: This community-based empowerment program through health cadres proved effective in improving knowledge and behavior related to TB prevention. To ensure program sustainability, it is recommended to establish a monthly cadre forum facilitated by the community health center (Puskesmas), integrate the TB education module into routine Posyandu activities, and develop adaptable intervention designs for other agricultural areas with similar characteristics.
