Sistem Kendali Mikroklimat Greenhouse Cerdas Berbasis Hybrid GA-LSTM dan Fuzzy Logic Controller

2026-02-21T05:21:07+00:00

Controlling temperature and humidity in greenhouses is a complex challenge due to its non-linear nature and dependence on external weather conditions. Conventional control methods often experience energy inefficiency and delayed responses to drastic changes. This study proposes a hybrid approach by combining Long Short-Term Memory (LSTM) optimized using Genetic Algorithm (GA) for temperature prediction, and Fuzzy Logic Controller (FLC) for actuator decision-making. Genetic Algorithm is employed to find optimal hyperparameters (number of neurons and batch size) in the LSTM architecture. Experimental results demonstrate the GA-LSTM model's capability in predicting temperature with high accuracy, yielding an R² score of 0.9881 and Root Mean Square Error (RMSE) of 1.1273°C. These accurate predictions are subsequently used as input to the FLC to regulate exhaust fan speed and mist pump status. Simulations demonstrate the system's capability in making energy-efficient decisions—activating actuators only when conditions are predicted to deviate from ideal values—while remaining responsive to extreme temperature anomalies.

Strategi Komunikasi Efektif Pengelolaan Arsip Digital untuk Mendukung Layanan Inklusif bagi Disabilitas Tuli di PT KAI Tahun 2025

Effective communication is a pivotal component in the provision of inclusive digital archive services, particularly for individuals who are Deaf and depend on visual communication and Indonesian Sign Language (Bisindo). The objective of this study is threefold: first, to analyze the communication process in the management of digital archives at PT Kereta Api Indonesia (Persero); second, to identify communication barriers experienced by Deaf individuals; and third, to formulate strategies for developing inclusive digital archive services. The research employs a descriptive qualitative approach with participatory observation, interviews, and documentation studies at the Section of Asset Ownership Document and Files (USDA) of PT KAI. Participatory observation was conducted to directly observe the steps in using the Rail Document System (RDS), the workflow of digital archive services, and the interactions between Deaf and hearing staff members. Over two months, in-depth data were collected through observation, interviews, and documentation involving seven informants, both internal and external. The results indicate that the management of PT KAI's digital archives has been technically well-executed; however, it does not fully accommodate the needs of Deaf users. The study proposes several recommendations, including the integration of Indonesian Sign Language (Bisindo) into the digital archive system, the provision of content or features accompanied by visual guides, the implementation of sign language training for PT KAI employees, and the reinforcement of internal company policies and regulations. These recommendations aim to ensure the provision of equitable and inclusive digital archive services at PT KAI

Representasi Unsur Jawa dalam Film Ketika Cinta Bertasbih 1 (Analisis Semiotika Charles Sanders Peirce)

2026-03-09T16:36:51+00:00

This study examines Javanese cultural values found in the religious theatrical film Ketika Cinta Bertasbih 1. The research question addressed is what signs and meanings represent Javanese cultural values in the film. The approach used is semiotic analysis, focusing on symbolic meaning as the object of study. The research method applied is descriptive qualitative, which prioritizes depth of meaning over generalization of results. The data in this study consist of verbal and non-verbal texts. Verbal texts include spoken and written language, while non-verbal texts take the form of images and setting backgrounds contained in the film. Data were collected through an observation and note-taking technique, comprising: (1) watching the film, (2) recording relevant information, (3) collecting data through screenshots, (4) sorting the data, and (5) analyzing the data to draw conclusions. This study employs the semiotic framework of Charles Sanders Peirce, focusing on symbolic meaning as the unit of analysis. The findings reveal 4 images and narratives carrying symbolic meanings related to Javanese cultural elements, particularly through the use of Javanese vocabulary and settings located in Central Java.
