Abstract

Treatment techniques using herbal remedies combined with Qur'anic verses are alternative treatment methods that have been practiced since the time of Prophet Muhammad. One of the medicinal plants used as a traditional herb is the sendok plant (Plantago major). Sendok leaves are known to have antibacterial properties that can be used to treat bacterial infections, especially amidst the challenges of bacterial resistance to synthetic antibiotics. The aim of this study is to explore the effect of spiritual methods on enhancing the therapeutic properties of Sendok leaves. After being treated with Qur'anic recitation, the leaves of the plant were analyzed for their chemical content, and bioactivity testing was carried out. The results showed a quantitative difference in the chemical compounds, as determined by GC-MS analysis. Antibacterial testing also revealed an increase in bioactivity, especially against Staphylococcus aureus bacteria, in the plants that received Qur'anic recitation treatment.

Abstract

The incidence of breast cancer in Indonesia is steadily rising. Women have the highest incidence of breast cancer. Acetogenins are highly effective inhibitors of mitochondrial complex I or NADH dehydrogenase, making them a promising option for therapeutic creation against breast cancer. The plant known as Annona muricata, also referred to as the soursop leaf plant, is purported to possess the ability to suppress the activity of breast cancer. Hence, it is imperative to assess the chemical composition of soursop leaves on receptors by docking experiments. Research utilizing the active site on the alpha estrogen receptor has determined that the reticulin molecule, with a free energy of -8.14 kcal/mol, is a potential contender for breast cancer therapeutic medications. Reticulin exhibits the highest affinity for binding to the active site of estrogen receptor alpha. This chemical exhibits the capacity to impede the growth of breast cancer.

Abstract

Kampar Polytechnic has a miniplan laboratory for processing CPO into cooking oil, biodiesel, and soap. During its operation, this processing produces liquid waste and solid waste. The waste released must be treated before being discharged into the environment, provided that the amount of COD reduction efficiency is good enough (63,41%). The COD content in wastewater is still above environmental quality standards. To reduce COD according to permissible standards, recycling is carried out with effluent from the sedimentation process returned to the equalization unit. The design of equalization, coagulation, and flocculation tubs has been successfully carried out. The results obtained are the dimensions of the equalization bath at 2m length, 2m width, and 1.2m height. The dimensions of the coagulation bath are 1.5m long, 1.0m wide, and 1.2m high. The dimensions of the flocculation bath are 2.5m long, 1.5m wide, and 1.2m high, with the provision that consideration meets the volume of liquid waste treated.

Abstract

This study aims to examine the process of making raw noodles, analyze costs, revenues, profits, business feasibility, and the challenges faced during production. The research uses a case study method focused on the home industry business Widodo Food. Data collected includes both primary and secondary sources. The noodle-making process involves ingredient preparation, mixing, sheet formation, noodle cutting, rolling, and packaging. The results show the total cost of the raw noodle business is IDR 158,510,329 per month, with a production volume of 20,020 kg per month and a selling price of IDR 13,000 per kg. Consequently, the business generates a monthly revenue of IDR 260,260,000 and a profit of IDR 101,749,671. With an R/C Ratio of 1.64, the business is considered feasible. Challenges include damage to the roll press machine, power outages, and the lack of complete personal protective equipment (PPE) for employees.

Abstract

Protecting information during transmission is crucial to prevent unauthorized access. Steganography and cryptography are two commonly used methods for securing messages from illegal interception. Steganography involves two main components: a container and a secret message to conceal. This research focuses on embedding a message into an encrypted video. The embedding process utilizes the Least Significant Bit (LSB) algorithm, while encryption and decryption are performed using the RSA algorithm. In the LSB technique, the last two bits of the red component in each pixel are replaced with two bits from the encrypted message. Once replaced, the red value in each pixel is updated accordingly. Video steganography enhances message security by minimizing the likelihood of detecting hidden messages within the video. By combining the LSB method with RSA encryption, the confidentiality of the information is further strengthened.

Abstract

North Sumatra is one of the provinces that contributes the most prominent agricultural commodities of red chilies and cayenne peppers in Indonesia. This study aims to determine the outcomes of price forecasts for cayenne and red chilies in the province of North Sumatra. The method used is multivariate singular spectrum analysis. Results were grouped into six groups based on 12 eigenvectors with a forecast length of 9 monthly periods. Further, the level of accuracy was obtained from MAPE for each variable, with the highest MAPE being 30% for the curly red chili, 27.55% for the big red chili, and the lowest at 23.44% for mixed cayenne pepper. So, the price forecast for red chilies and cayenne peppers in North Sumatra Province for October 2023 to June 2024 using the Multivariate Singular Spectrum Analysis model is included in the forecast category with reasonable capabilities.
