This study examines the decline in the usage of the Javanese language, which has experienced a decrease in the number of speakers from approximately 82 million in 2007 to 68.2 million in 2015. The convergence of the Javanese script and Optical Character Recognition (OCR) technology is proposed as a solution, allowing for the preservation and accessibility of the Javanese script in the digital age. The integration of Convolutional Neural Networks (CNNs) in Javanese script classification achieved a high accuracy rate of 92.95% in identifying positive and negative cases. The dataset used for training consisted of 8440 sample images, which were divided into 20 subfolders for training and testing. The results presented in Table IV demonstrate the successful implementation of the classification model, achieving a 98.87% sensitivity, 100% precision, and 98.88% specificity. This research contributes to the preservation and understanding of the culturally significant Javanese script while addressing the decline in its usage.

One of the methods used to increase channel capacity is the Non-Orthogonal Multiple Access (NOMA) methods. The increase in channel capacity in PD-NOMA multiple access means that the maximum power used by each user in each narrow band achieves increased power efficiency. Therefore, this research focuses on facilitating the increase in channel capacity by designing an antenna that produces a radiation pattern with many sharp main lobes and high gain. The multi-beam radiation pattern is obtained by using edge weighting. Therefore the antenna is designed with odd and even numbers represented by 1x5 and 1x6 antennas on the microstrip patch rectangular antenna at a frequency of 2.6 GHz. The effect of parasitic and non-parasite effects on the radiation pattern of a planar antenna with edge modeling is manageable in the main lobe, only in the side level lobe, which is not too significant. However, the number of main lobes on the 1x6 antenna has seven beam patterns, and the 1x5 antenna has five. The highest gain value obtains in the 1x6 design with a parasitic of 6.01 dB. This value meets the Gain requirements for 5G cellular systems.

To determine the quality of beef, it is usually seen using a flashlight and matching it with a predetermined color standard. However, this method is time consuming and the results are inconsistent due to human visual limitations. This study aims to identify the freshness of beef based on its color characteristics using feature extraction method with HSV and LDA method for identification. The identification process begins with the transformation process from RGB images to L∗a∗b, then image segmentation serves to separate one object from another and image identification uses the LDA method with feature extraction using HSV. The use of color feature extraction with the HSV algorithm to assist in obtaining information from the colors contained in the image for easy identification. Furthermore, the LDA algorithm has a function to obtain the maximum projection to obtain a smaller dimensional space so that the desired patterns can be separated through the boundary line of a linear equation so as to form a certain class or group. Based on the test results using the confusion matrix, it produces a precision value of 80%, recall of 84%, and accuracy of 82%. © 2022 IEEE.

Foaming agents for fire suppression on peatland were formulated from the saponification product of palm oil fatty acids, namely sodium laurate and potassium palmitate. This study aimed to obtain the best formulation of sodium laurate and potassium palmitate as raw material for foaming agent concentrate through formula selection based on physical parameters foaming ability, foam stability, and surface tension. In addition to obtaining the best formula, foam liquid performance test for the foaming agent was also conducted on the peat fire suppression applications. Formulation of sodium laurate and potassium palmitate that produce the best foaming agent concentrate was 20% sodium laurate, 5.58% potassium palmitate, and 74.42% water, which produced a foaming response of 393.58%, foam stability of 69.59%, and surface tension of 31.11 dyne/cm. Foam performance test for the mixture of water and foaming agent showed that peat fire could be extinguished in 3 h 50 min 42 s using 4.56 L/m2 extinguishing solution. Meanwhile, fire suppression with water requires 5 h 31 min 59 s, with the application of 9.72 L/m2 solution. Water mixed with a foaming agent concentrate can extinguish peat fires faster than using water alone, besides being faster the application of foaming agents can reduce water consumption. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Waste generation from food manufacturing facilities poses a serious hazard like environmental degradation, water pollution, and land pollution due to its high nutrient composition. Specifically, solid waste(powder) disposal requires additional energy sources in terms of scientific treatment, structured collection, and disposal packaging according to the safety regulation. Thus, this research discusses the viewpoint of integrating food processing waste as an organic carbon source with BG-11 medium for Chlorella vulgaris(FSP-E) growth. The food processing waste powders investigated in this study were obtained from milk, and biscuit manufacturing facilities. The culture medium was modified by combining both BG-11 and food processing waste powders to identify the optimal algal growth and biochemical *** to the microalgae grown in BG-11 alone(IBG), the combination of biscuit waste and IBG produced higher biomass concentration(44%), with increased lipid(11%), protein(20%), and carbohydrate(57%) contents. Chlorella vulgaris was able to uptake nutrients from the culture medium with combination of food processing waste and IBG thus enhancing its growth. The results obtained also indicate that an integrated culture system using food processing waste and synthetic sources can generate energy out of waste by improving the bio-composition of the microalgae biomass.

The development of telematics technology is increasing rapidly and this capability is supported by multimedia devices or even telematics that supports the development of multimedia itself. For instance, in the configuration of telematics with websites to control air traffic with a voice communication system, multimedia applications serve as devices for monitoring the use of this technology. Consider the research trends, this study aims to evaluate the current development and trends of research on telematics and its multimedia applications through bibliometric analysis over the last two decades and a half (1999-2023). Several publication characteristics were analyzed, including the most cited articles in this field. This study uses data from the Scopus database to evaluate the productivity, impact, countries, research institutions, authors, and research performance of journals based on the impact factor, citation counts, and h-index. According to the result, the annual number of publications on this topic fluctuates but tends to increase, with Germany being the most prolific country producing articles in this field. Additionally, the most researched telematics and its multimedia applications and most cited lists offer insight into the future. This is the first study to use bibliometric analysis to evaluate research on telematics and its multimedia applications and is expected to be useful for telematics researchers by identifying potential research directions. In addition, this research serves as a valuable resource for future researchers and practitioners. However, improvements can be made by incorporating additional analysis, such as content analysis. © 2023 IEEE.
