Abstract

When sending a message to a specific party and do not want the message to be known by other parties, it is important to avoid information leakage. However, the problem identified is that there is a lack of knowledge to detect audio Ste-ganography which requires technical methods that can read and view secret messages. One method that can be used in steganography is Masking and Filtering. Masking as a media marker on audio that can insert messages. Filtering gives value to the parts that have been given a mark.  This method is one that is often used because it is simple, fast in the data insertion process, and has a large enough storage capacity. The Masking and Filtering method is able to hide messages by inserting them into the audio Spectrogram as a storage medium. The filter is used to ensure that the hidden message is within the previously analyzed frequency range, thus making humans unable to clearly hear the additional audio that has been inserted which is the hidden message.  After the insertion is complete, the audio file is saved, and tests are performed to ensure that the audio quality is not compromised, and the hidden message remains undetected such as making modifications to the stego file to test the robustness and security of the hidden message. Based on research, steganography is difficult to detect by the naked eye, to retrieve messages that have been hidden, it can be done by displaying an audio Spectrogram that contains a secret message. How to see the hidden message using the Audacity application that can see sound waves. The result is that the message embedded in the audio is not damaged even though compression, cutting, and some of the processes carried out in the audio have been carried out.

Abstract

Agricultural waste, especially from rice such as straw, husks, and bran, is one of the abundant biomasses in Indonesia, particularly in Sleman Regency, DI Yogyakarta, which is one of the regions with the highest rice productivity. The potential of rice waste can be used as a source of bioenergy using a biorefinery approach. The concept of a biorefinery is the processing of biomass that produces various products and by-products to achieve sustainability. The analysis of the potential of this biomass waste was conducted using p-graph and techno-economics. Based on the optimization analysis with the p-graph, the optimal and maximal solutions were obtained after running the superstructure flow. The optimal solution indicates that the transesterification process of rice bran into biodiesel is more feasible with a profit of 9000 USD/year. For the maximal solution, an economic analysis was conducted because the products generated are more numerous, allowing for the implementation of a biorefinery approach. The results of the techno-economic analysis show that the production of several bioenergy products will fully recoup the initial investment by the 8th year. The IRR value obtained is 21.7%, while the MARR (Minimum Attractive Rate of Return) is 15%, indicating that the investment is viable for funding. Additionally, from an environmental perspective, the use of biomass waste for bioenergy production has a positive impact by reducing greenhouse gas emissions and pollution, as well as enhancing soil fertility through the application of biochar. From a social perspective, community-based bioenergy production can increase income, improve community welfare, enhance bioenergy production, and support energy independence and sustainability.

Abstract

This study aims to develop a reminder application system for patients with hypertension and diabetes mellitus (DM) to improve medication adherence and health monitoring. Hypertension and diabetes are non-communicable diseases whose prevalence continues to rise in Indonesia, with Puskesmas Ngaglik 1 as the study location showing low patient compliance with the chronic disease management program (Prolanis). Using the User Centered Design (UCD) method, this research involves users at every stage of system development, from problem identification, literature review, to prototype creation. The results indicate that the developed application can assist patients in remembering their medication schedules, routine check-ups, and exercise, as well as providing emergency features to enhance interaction between patients and Prolanis staff. Prototype evaluation was conducted through two iterations, demonstrating that the resulting system meets user needs. Users say that the system built can help in the Prolanis program and improve discipline in patients.

Abstract

This study aims to analyze the impact of hospital wastewater utilization on groundwater quality using secondary data and Modflow visual modeling. This model is used to visualize the spread of contaminants from the effluent of the Wastewater Treatment Plant (IPAL) of Hospital X into the soil, as well as to measure the concentration of wastewater parameters such as TSS, COD, oils and fats, BOD, ammonia, residual chlorine, and fecal coliform at various distances from the source point. The modeling results show that all wastewater parameters meet the established quality standards, with a significant reduction in concentration along the spread distance. The TSS concentration almost reaches 0 (0.01 mg/L) at a distance of 115 meters from the source, while the concentrations of COD, oils and fats, and BOD decrease to 0.25 mg/L, 0.01 mg/L, and 0.02 mg/L at the same distance, respectively. Additionally, ammonia and residual chlorine concentrations are almost undetectable at 115 meters, while fecal coliform also decreases to 0 MPN/100 mL. Based on these results, the utilization of hospital wastewater with the new IPAL system is expected not to have a negative impact on groundwater quality within a certain radius, as the concentration of wastewater parameters continues to decrease with increasing distance from the source.

Abstract

This study aims to determine the sub-districts that have the potential to be growth centers and hinterland areas in Kulon Progo Regency and to analyze the magnitude of the interaction between growth centers and supporting areas. This type of research is quantitative descriptive using scalogram analysis and gravity analysis methods. This study was processed using Microsoft Excel 2013. The results of the scalogram analysis study show that in 2020 there were three sub-districts as growth centers in Kulon Progo Regency, namely Wates District, Temon District, and Nanggulan District. In 2023, the three sub-districts will remain growth centers. The results of the gravity analysis revealed differences in distance between sub-districts which affect the magnitude of interaction between the growth center sub-districts and the Hinterland.
