Abstract

The environmental challenges faced by Batik Bujang and Batik Candafa, two Riau-based SMEs, stem primarily from the production process, which generates substantial wastewater containing harmful chemicals. The improper disposal of these by-products poses serious risks to water bodies and surrounding ecosystems. This research aims to design a waste management system using eco-friendly technologies capable of processing up to 40 liters of wastewater, thereby minimizing environmental harm. A mixed-method approach was adopted, combining quantitative analysis of waste volume and chemical composition with qualitative insights from SME owners. The findings indicate a significant reduction in chemical pollutants post-treatment, aligning with eco-sustainability goals. This study fills the research gap by providing a technological solution specifically tailored to the needs of small-scale batik producers, emphasizing sustainability and environmental responsibility.

Abstract

Mental health in adolescents aged 18-24 years is a real condition and a problem that has received less attention from parents or certain parties. Individual adolescents free from all forms of symptoms of mental disorders are one of the keys to maintaining a healthy body from mental health disorders . The group most vulnerable to mental health disorders is adolescents, where many adolescents do not receive the care they should from their parents. Expert systems can help solve problems in the field of mental health in adolescents aged 14-18 years as befits a psychiatrist by adopting expert knowledge into computers. This study aims to develop an expert system for diagnosing mental health disorders in adolescents aged 18-24 years using the Certainty Factor (CF) method by combining expert and user belief values in the diagnostic solutions provided later by the expert system. This study used five mental disorders in adolescents aged 18-24 years, namely depression, schizophrenia, bipolar, obsessive, anxiety disorders which were later given the weight of symptom beliefs and data on preventive solutions to the disease using the CF method . The results of the study are in the form of an expert system for diagnosing mental health in adolescents. using the CF method which displays the certainty value of expert knowledge diagnosis. Testing of the expert system application in this study uses the black-box method with valid test results used.

Abstract

The Village Fund Direct Cash Assistance (BLT) Program is a government initiative aimed at improving social welfare, reducing inequality, and supporting economically disadvantaged communities. However, in practice, the process of determining BLT recipients often faces issues of subjectivity and lack of transparency. This study aims to develop a Decision Support System (DSS) to assist village authorities in selecting BLT recipients objectively and accurately by utilizing the Rank Order Centroid (ROC) and Weighted Aggregated Sum Product Assessment (WASPAS) methods. The ROC method is used to assign weights to each criterion based on their level of importance, while the WASPAS method is applied to rank the recipient candidates according to the established weights. The DSS is developed as a web-based application to ensure easy access for village administrators. System testing results indicate that the ROC method consistently generates weights that reflect the prioritization of criteria, while the WASPAS method proves effective in producing final rankings of potential recipients. As a result, village leaders can make more objective and targeted decisions in determining BLT beneficiaries.

Abstract

Penelitian ini bertujuan untuk merangking kualitas salah satu jenis kopi yaitu kopi Arabika. Biji kopi arabika merupakan salah satu jenis utama kopi yang berkembang di Indonesia dengan menerapkan salah satu metode yang digunakan dalam Sistem Pendukung Keputusan (SPK) yaitu metode Elimination Et Choix Traduisant la Réalité (ELECTRE). Metode ELECTRE merupakan metode pengambilan keputusan untuk menyelesaikam masalah penentuan pilihan yang bersifat multi objective diantara beberapa kriteria, sehingga menghasilkan suatu analisa yang efektif dan efisien. Kriteria-kriteria input yang menjadi prioritas dalam penentuan kualitas kopi arabika yang relevan yaitu aroma, rasa, keasaman, body, keseragaman, keseimbangan, clean cup, rasa manis dan cupper point.

Abstract

The rapid growth of digital applications in population administration services has increased the importance of sentiment analysis to understand user perceptions more deeply. This study focuses on the Digital population identity (Identitas Kependudukan Digital, IKD), a digital identity application developed by the Indonesian government. It aims to classify user reviews of the IKD application into positive, neutral, and negative sentiments using the random forest algorithm. The dataset consisted of 28,134 user reviews from the Google Play Store, including usernames, review texts, timestamps, and star ratings. The research stages included data preprocessing, labeling, handling missing values, and text processing (cleansing, tokenizing, stopword removal, and stemming). The data were divided into 80% training and 20% testing sets. The best-performing model used the parameters: max_depth=None, max_features=log2, min_samples_leaf=1, min_samples_split=2, and n_estimators=300, achieving an average accuracy of 83.78%. To address class imbalance, the synthetic minority oversampling technique (SMOTE) was applied, resulting in improved performance with an accuracy of 86.29%. Evaluation metrics before SMOTE showed 83.85% accuracy, 80.40% precision, 83.85% recall, and 81.73% F1 score. After SMOTE, precision increased to 81.22%, while accuracy and recall slightly decreased to 80.86%, with an F1 score of 81.03%. Furthermore, sentiment trend analysis using N-gram techniques (unigram, bigram, trigram) was conducted to identify frequently mentioned topics and user concerns. These insights support the research objective of guiding application improvements aligned with user needs and enhancing the overall digital service experience.

Abstract

Laptops have become essential in the world of work, education, and society. With a laptop, tasks such as creating reports, sending data, learning, and even entertainment become easier. However, the variety of laptops available with different specifications can confuse people when choosing one that suits their profession and status. This confusion often leads to wasted time and the risk of choosing a laptop that does not meet their needs. Therefore, a decision support system (DSS) is needed to provide laptop recommendations based on desired criteria. In this study, the method used is a collaboration of Analytical Hierarchy Process (AHP) and Multi-Objective Optimization By Ratio Analysis (MOORA). AHP is used to calculate the weight of laptop criteria according to desired criteria, while MOORA is used to rank the recommended laptop values suitable for use. The implementation of the AHP and MOORA methods in this study resulted in laptop recommendations that meet the desired criteria and specifications of the community. Based on manual calculations in this study, the top-ranked laptop recommendation is alternative A8, the HP Victus Gaming Laptop 15 with a Yi of 0.424, followed by alternative A2, the HP Pavilion Gaming 15 with a Yi of 0.382. This study is considered successful because the results of manual calculations and those of the system built are consistent. Thus, the implementation of AHP and MOORA methods in a web-based system can be used for laptop recommendations.
