Abstract

This study investigated the effect of solvent variations on oil yield in avocado pear seed extraction. Avocado seeds were dried, ground, and extracted using Soxhlet apparatus with three different solvents: petroleum ether, normal hexane, and methylene chloride. The extraction process was carried out at different temperatures (50°C, 60°C, and 70°C) for 2 hours each. The oil yield was calculated and compared among the three solvents.Results showed that methylene chloride solvent produced the highest oil yield, followed by petroleum ether, while normal hexane yielded the least. However, there was no significant difference in oil yield between petroleum ether and normal hexane. The findings suggest that solvent variation significantly affects oil yield in avocado pear seed extraction, and methylene chloride is the most effective solvent for optimal oil yield..

Abstract

An adhesive, known by various names such as glue, cement, mucilage, or paste, is a material applied to one or both surfaces of two distinct items to unite them and withstand any attempts to pull them apart. Adhesives can occur naturally or be artificially manufactured. In this specific context, the discussion centers on the utilization of acrylic and polyvinyl acetate (PVA) as the base materials for the adhesives under consideration.,In the process of formulating the adhesive, approximately 2 liters of water were measured and then poured into a plastic bucket, which served as the mixing vessel. Subsequently, 0.7 kg of calcium carbonate was introduced into the water-filled bucket and stirred for thorough blending. Following this, 0.5 kg each of acrylic and polyvinyl acetate (PVA) were added to the mixture in the bucket and stirred diligently until a uniform and well-integrated blend was achieved.Subsequently, 0.1 kg of nitrosol and 0.07 kg of bamacol powder were incorporated into the mixture, followed by continuous stirring to ensure a uniform blend. Additionally, 0.05 kg of formalin was introduced as a preservative and stirred for approximately ten minutes to finalize the product. The adhesive's performance was then evaluated by testing its bonding properties on various material combinations, including wood-to-wood, carton-to-carton, paper-to-paper, wood-to-metal, and paper-to-wood applications.The results indicated that the white adhesive serves as a versatile, multipurpose product when applied. Various properties such as drying time, bonding strength, and pH levels were tested to determine the optimal qualities of the adhesive. Additionally, the shelf life of the formulated adhesive was thoroughly examined. Ultimately, the adhesive demonstrated its effectiveness in bonding paper-to-paper, paper-to-wood, and other packaging materials, showcasing its versatility and practicality in various applications.

Abstract

The effectiveness of liquid soap and NPK fertilizer in enhancing bioremediation of petroleum hydrocarbon-contaminated soil was investigated. Artificially polluted soil with 1% density of crude oil was treated with emulsifier (liquid soap) and NPK fertilizers at 3 levels of 0, 1, and 2 ton/ha in 3 replicates. The soils were incubated at 30°C and 60% field capacity for 0-4 weeks. Results showed that the pH increased from 4.74-7.01, conductivity increased from 17.00-1873.00 µS/cm, and TPH decreased from 585.28-349.22 mg/kg. The application of liquid soap and NPK fertilizer increased the remediation of oil-contaminated soil, with a significant decrease in TPH content (from 585.28 mg/kg to 349.22 mg/kg) observed in the treatment with liquid soap. The results indicate that bioremediation is a viable strategy for remediating petroleum hydrocarbon-contaminated soil, and the addition of liquid soap and NPK fertilizer can enhance the process.

Abstract

Steganography is a technique for hiding confidential information within a digital medium so that the existence of the information is not easily detected by unauthorized parties. Digital images are commonly used in steganography because they contain high data redundancy and are widely used in modern communication. One effective approach in image steganography is the transform domain approach, particularly the Discrete Wavelet Transform (DWT). DWT transforms image representation from the spatial domain into a multi-resolution frequency domain consisting of several sub-bands. Secret message embedding is performed in certain frequency sub-bands that are not highly sensitive to human visual perception, thereby preserving the quality of the stego image. This study aims to implement a DWT-based steganography method and evaluate its performance based on stego image quality and message extraction success. The evaluation is conducted using Peak Signal-to-Noise Ratio (PSNR) and Mean Square Error (MSE) metrics. The test results show that the DWT method is capable of producing stego images with very good visual quality, with an average PSNR value above 40 dB, and a 100% message extraction success rate. This demonstrates that the DWT-based steganography method is effective in maintaining digital information security.

Abstract

The rapid development of information and communication technology has led to an increase in the exchange of digital data, particularly in the form of multimedia such as video. This condition creates a need for data security systems capable of maintaining the confidentiality of information from unauthorized parties. Steganography is one of the information security techniques that aims to hide secret messages within digital media without causing noticeable changes to the media. This study aims to implement the Motion Vector Steganography method on video media as an effective and secure technique for hiding secret messages. This method utilizes motion vectors generated during the video compression process, particularly in P-frames and B-frames, as the medium for message embedding. The research stages include analyzing video structure, embedding secret messages into motion vectors, and extracting messages from the stego video. The evaluation is conducted by comparing video quality before and after the embedding process using Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity Index (SSIM) parameters, as well as testing the success of message extraction. The results show that the Motion Vector Steganography method is capable of hiding messages effectively without causing significant degradation in video visual quality. In addition, the embedded secret messages can be successfully extracted with a high level of accuracy. Therefore, this method can serve as an effective alternative solution for securing information in digital video media.

Abstract

Steganography is a technique for concealing information by embedding a secret message into a digital medium without causing significant visual changes. In this study, a transform-domain-based video steganography method using the Discrete Cosine Transform (DCT) is implemented to embed secret messages into video media. The embedding process is performed on each video frame by dividing the frame into 8×8 pixel blocks, followed by applying DCT to each block. The secret message is converted into a bitstream and embedded by modifying the mid-frequency coefficients in the DCT domain. After the embedding process, inverse DCT is applied to reconstruct the frame back into the spatial domain, resulting in a stego video. The test results show that the visual differences between the stego video and the original video are not significantly perceptible, thus satisfying the imperceptibility aspect of steganography. In addition, the secret message can be successfully extracted with a high level of accuracy, indicating that the proposed method is capable of maintaining a balance between embedding capacity, visual quality, and extraction reliability. Therefore, the transform-domain-based video steganography method using DCT can be effectively used as a solution for embedding secret messages in video media.

Abstract

The rapid development of information technology demands the existence of data security systems capable of protecting confidential information from unauthorized parties. One technique that can be used to maintain information confidentiality is steganography. Steganography is a technique of hiding secret messages within a cover medium so that the existence of the message cannot be directly detected. This study aims to implement an audio steganography method for embedding secret messages into digital audio media. The method used is the Least Significant Bit (LSB), in which the secret message is embedded in the lowest bits of the audio data without significantly altering the audio quality. The research process includes the stages of audio data preparation, secret message embedding, and message extraction. The test results show that the secret message can be successfully embedded and extracted without causing significant changes in audio quality. Therefore, the LSB-based audio steganography method can be used as an effective alternative for data security.

Abstract

The advancement of information technology has created a growing need to protect confidential data from unauthorized access. Steganography is a technique for hiding information within digital media so that its existence cannot be detected. This study implements a Frame-Based Least Significant Bit (LSB) steganography method to embed secret messages into digital video media in AVI format. This method works by extracting frames from the video, modifying the least significant bit of pixel values in the blue channel of each frame, and then reconstructing them back into a video. The implementation was carried out using the Python programming language, with the OpenCV library for video manipulation and CustomTkinter for the user interface. The testing results show that the system is capable of embedding and extracting messages with a 100% success rate in AVI videos using the FFV1 (lossless) codec. The embedding capacity depends on the video resolution and the number of frames. A video with a resolution of 1920×1080 at 30 fps for 10 seconds can store up to 207,360,000 bits or approximately 24 MB of data. This method preserves the visual quality of the video with changes that are imperceptible to the human eye.
