Get PDFThis research aims to analyze the feasibility of implementing an environmental management system based on ISO 14001:2015 at one of fertilizer company in Madiun, a small and medium-sized enterprise engaged in the production of NPK fertilizers located in Madiun, East Java. The research method used is a descriptive qualitative approach employing the PDCA (Plan-Do-Check-Act) framework, with a focus on evaluating the implementation of clauses 4, 6, and 8 of the ISO 14001:2015 standard. The research findings indicate that the company has not yet fulfilled most of the essential requirements, with an average feasibility score of 1,37 out of a maximum of 5,00. Key issues identified include the absence of formal context analysis, lack of documented environmental aspects and impacts, absence of monitoring and evaluation of environmental performance, and no structured corrective actions. Although there are initial efforts in environmental control, such as the construction of an ammonia filtration pond using zeolite, the environmental management system implementation remains minimal and underdeveloped. Based on these findings, it is concluded that company is not yet eligible for ISO 14001:2015 certification without significant system improvements. Key recommendations include developing systematic environmental documentation, enhancing employee environmental awareness, strengthening environmental performance monitoring, and ensuring top management commitment toward continuous improvement
Klasifikasi Sertifikat Berdasarkan Mata Kuliah dalam Program Rekognisi Pembelajaran Lampau Berbasis NLP Menggunakan BERT
Get PDFThe rapid advancement of information technology has increased the demand for automated systems to recognize non-formal learning, particularly through the Recognition of Prior Learning (RPL) program. Competency certificates obtained from independent training programs are often not systematically integrated into academic curricula. This study aims to develop an automated classification model capable of categorizing certificates into relevant course subjects within the Informatics study program. Seven target course categories were defined, including Machine Learning, Web Programming, Interface Design, Computer Networks, Game Applications, Mobile Programming, and Project Management. The methodology includes extracting text from certificate documents in PDF format through Optical Character Recognition (OCR) using PyTesseract, followed by text praproses and data Augmentation to improve class distribution. The implemented
model is BERT (Bidirectional Encoder Representations from Transformers), evaluated in two configurations: bert-base-uncased and bert-base-multilingual uncased. Five data scenarios were tested: no Augmentation, Character Insertion, Character Deletion, Back Translation, and Synonym Replacement. Evaluation results indicate that the bert-base-uncased configuration with Synonym Replacement Augmentation yielded the best performance, achieving a validation accuracy of 95.54% and an F1-score of 0.97. These findings confirm the effectiveness of BERT for text classification in both Indonesian and English, and highlight the benefit of semantic-based Augmentation techniques in improving model generalization. As a practical implementation, this research also developed a prototype service using the Streamlit framework, enabling automated certificate classification through a user-friendly interface. The model and system developed are expected to support the efficient and accurate integration of non-formal competencies into academic programs

PEMBUATAN INVENTORY WEB MENGGUNAKAN LARAVEL PT TJAKRINDO MAS
Get PDFWhen a website developer has an idea for a new product, it is important to conduct a
thorough information systems analysis before the idea is realized. The initial idea usually
appears as a concept in someone's head or a rough sketch on paper. However, before the idea
is mass produced by the company, an initial version or sample of the product is usually created,
known as a prototype. At PT Tjakrindo Mas, systems analysts were given the opportunity to
develop an innovative website that focuses on information systems analysis. The aim of this
website is to benefit users by providing relevant resources and information in this area. The
"System Analyst IT" website development process is carried out by utilizing various
sophisticated web creation tools. These tools include programming languages such as HTML,
CSS, and JavaScript, as well as database management systems such as MySQL. In addition,
modern frameworks such as Laravel are used to ensure development runs efficiently and the
final result meets expectations. By utilizing this technology, the system analysts at PT Tjakrindo
Mas were able to complete the "System Analyst IT" website development project optimally.
This site is designed to help users find recommendations regarding the best tools,
techniques, and methodologies in information systems analysis. The development of this
website included not only the creation of an initial prototype but also further refinement so that
the site could become a comprehensive and useful resource for users. In the end, this project
became part of the Field Work Practice which aims to provide practical and in-depth
experience in developing websites that can meet user needs. Through continuous development,
it is hoped that the "IT System Analyst" website can become a reliable guide in information

OPTIMASI PROSES EKSTRAKSI PEKTIN DARI KULIT RAMBUTAN (Nephelium lappaceum) MENGGUNAKAN PULSED ELECTRIC FIELD (PEF) DENGAN METODE RESPONSE SURFACE METHODHOLOGY (RSM)
Get PDFRambutan peel is a waste that is less optimized, containing cellulose, hemicellulose, and pectin. Pectin is a polygalacturonate that can be used as an emulsifying agent. Pectin extraction can be carried out using Pulsed Electric Field (PEF), which has the advantages of short extraction duration and relatively low temperature application. The purpose of this study is to obtain the best combination of treatments (electric field strength, extraction time, and solvent ratio) in PEF-assisted extraction to optimize pectin from binjai rambutan peel. The method applied is One Factor at a Time (OFAT) in the preliminary experiment, and Response Surface Methodology (RSM) in the optimization stage. Preliminary test data were analyzed by analysis of variance using Duncan Multiple Range Test (DMRT) at α 5%. Optimization data were analyzed using Design Expert 13 with Central Composite Design (CCD) type. Optimum pectin was obtained under extraction conditions of 20 kV/cm electric field strength, 12.69 minutes extraction time, and 1:30 b/v solvent ratio, resulting in pectin with 4.37% yield, 676.81 mg equivalent weight, 8.76% methoxyl content, 75.72% galacturonic acid content, 65.66% degree of esterification, 9.78% moisture content, and 4.98% ash content. Optimum pectin is classified into High Methoxyl Pectin (HMP) based on the International Pectin Procedure Association (IPPA) standard. Further analysis includes pectin functional groups using Fourier Transform Infrared Spectroscopy (FTIR) and material damage using Scanning Electron Microscope (SEM). Optimum pectin has O-H, C-H, C=O, C-H₃, and -O- functional groups in the FTIR test, which are in accordance with the characteristics of commercial pectin and literature. SEM test results showed that the use of PEF caused damage to the surface of rambutan powder
