Abstract

Every manufacturing company must have experiencing building a layout. Fred.E Meyers has stated that only death and taxes are certain, there exist a third certainty-a plant layout will change, thus many methods to generate layout are established and each has its own purposes and benefits. This research focused on the design of manufacturing facilities supported by in-depth analysis of Assembly process design with a high stresses on the Systematical Layout Planning ( SLP) and Flow Analysis method to facilitate an outcome of layout accordingly to the system needs. This is a real case study conducts with an objective of generating a recommendation layout for Home Appliances Company specifically for television plant

Abstract

Perguruan Tinggi adalah organisasi yang menyelenggarakan pendidikan tinggi. Aset penting dari Perguruan Tinggi di antaranya adalah  aset intelektual yang berupa penge-tahuan dan ilmu pengetahuan para dosen dan mahasiswa. Agar lebih banyak orang dapat menggunakan dan memanfaatkan pengetahuan dan kumpulan pengetahuan, pengetahuan perlu disimpan, disebarluaskan, diaplikasikan, dimanfaatkan dan digunakan untuk kesejahteraan manusia melalui organisasi atau perusahaan. Pengelolaan semua itu disebut Knowledge Management (Indrajit, 2006). Di dalam satu perguruan tinggi, ada beberapa jurusan dan program studi. Inisiatif untuk mulai melakukan Knowledge Management terkadang datang dari jurusan atau program studi, juga perlu dilakukan dulu suatu bentuk Knowledge Management dalam bentuk yang lebih kecil misalnya di tingkat jurusan atau dalam bentuk kelompok penelitian antar disiplin ilmu. Pada  tingkat ini,  dukungan finansial dari tingkat universitas belum tentu ada. Sehingga untuk membangun suatu sistem Knowledge Management yang berbasis web site sebagai penampungan informasi yang dapat diakses melalui internet, maka dipilih menggunakan program pembangun web yang murah dan pembelajaran untuk menggunakannya juga murah dan mudah, mengingat yang membangun web ini belum tentu seorang yang berpengalaman membangun web. Maka dalam tulisan ini,akan dibahas suatu hasil percobaan untuk membangun suatu web site dengan program Joomla, dimana program ini adalah open source dan cara pembelajarannya juga dapat dilakukan secara mandiri dengan metode e-learning.Kata Kunci: CMS, Knowledge Management, Perguruan Tinggi

Abstract

Accurate demand forecasting plays a critical role in inventory management and production planning, particularly in the manufacturing of heavy-duty filter products, where customer order patterns are influenced by seasonal and external factors. This study proposes a machine learning–based forecasting framework to predict incoming customer orders using structured sales data. The analysis focuses on the 2021–2025 period, during which demand behavior was observed to be more stable compared to previous years. The study evaluates the effects of feature engineering and feature selection on forecast accuracy, with special attention to time-based, seasonal, and external economic variables. Random Forest, LightGBM, and Linear Regression models were developed and their performance was assessed using metrics such as Mean Absolute Error (MAE), Root Mean Square Error (RMSE), MAPE, and R2 score. Experimental results show that the inclusion of seasonal and exogenous features significantly enhances model performance, particularly for item types with pronounced cyclical trends. Furthermore, the study conducts hypothesis testing to assess the statistical impact of engineered features and model types on forecast accuracy. The findings demonstrate the applicability of machine learning in industrial forecasting scenarios, offering a replicable and scalable approach to data-driven decision making in procurement and inventory planning.

Abstract

The purpose of this study is to design an LLM-powered chatbot that can assist small businesses in their HR business process, specifically to document knowledge. Employing the Design Science Research (DSR) methodology, the research progresses through problem identification, solution design, artifact development, demonstration, and evaluation phases. The proposed chatbot artifact is evaluated using the Retrieval Augmented Generation Assessment (RAGA) framework for technical performance and the Unified Theory of Acceptance and Use of Technology (UTAUT) for user acceptance. RAGA evaluation demonstrates strong performance, with average scores of 0.95 for context recall, 0.98 for response relevancy, and 1.00 for faithfulness, indicating the chatbot successfully maintains conversational focus and adheres to design specifications. UTAUT results reveal positive user acceptance, particularly in effort expectancy (average 3.30) and facilitating conditions (average 4.08), though employees continue preferring human interaction for complex knowledge-sharing tasks. This study uniquely contributes by developing the first LLM-based chatbot specifically designed for knowledge documentation in small IT enterprise HR contexts, combining technical rigor with practical implementation insights. The artifact design can be replicated and enhanced by future researchers exploring LLM applications in organizational knowledge management, with implications for democratizing advanced knowledge management capabilities in resource-constrained environments.
