Abstract

Messages require high security in the exchange process because the message is confidential and may only be read by the intended recipient. Information security problems in messages are often encountered, such as active eavesdropping, passive eavesdropping, fraud and data manipulation by unauthorized parties. To overcome this problem, cryptography can be used. This research uses cryptographic techniques with the Vigenere Cipher method to encrypt messages. The aim of this research is to encrypt messages to produce codes that will be sent to the recipient. The encryption process is carried out using the Vigenere Cipher method in the Python programming language. The researcher implemented a program to encrypt the message. The research results show that messages can be protected more strongly and securely. So, if the message is hijacked or intercepted by irresponsible parties, it will be difficult for them to find out the contents of the message. In this way, the confidentiality and authenticity of the message is maintained until it reaches the recipient.

Abstract

Computational thinking is a way of thinking that students must have. Currently, many students do not yet know how computing can be applied in mathematics learning. For this reason, this research focuses on analyzing students' computational thinking in mathematics learning. This research takes the type of literature study research by identifying and evaluating the results of previous research. Data analysis was carried out using an interactive model which uses 4 steps in the analysis stages, namely: 1) Data collection, 2) Data condensation, 3) Data presentation and 4) Data verification. This research identified 3 previous articles. From the results of this research, it was found that computational thinking in mathematics learning means that students can relate mathematical concepts to the real world, motivate learning and can link mathematics with everyday life.

Abstract

This study examines ethnomathematics in traditional tools of the Malay ethnic group at the North Sumatra Provincial Museum, encompassing ceremonial and livelihood tools. The research employs a qualitative approach using ethnographic methods to explore the mathematical concepts embedded in these objects. Ceremonial tools such as bentan, tiered trays, incense burners, and glass holders were analyzed based on geometric concepts such as circles, cylinders, ratios, and sequences, while livelihood tools such as goat hoofs, horns, sickle, and one-sided fish traps represent spatial geometry, symmetry, and volume concepts. The findings reveal that these traditional objects not only serve practical purposes but also contain mathematical and philosophical values reflecting Malay culture. These tools can be utilized as context-based mathematics learning media, helping students understand mathematics through the lens of local culture. This study emphasizes the significant role of ethnomathematics in integrating education with cultural preservation while strengthening local identity in the era of globalization.

Abstract

Pregnant women should prepare themselves to provide exclusive breastfeeding, due to the still relatively low breastfeeding achievement. Exclusive breastfeeding coverage in Mesuji District in 2022 was 67.17%, at Tri Karya Mulya Health Center with a target of 80% in 2022 was 45.57%. Efforts to increase breastfeeding achievement by providing education to pregnant women thus increasing knowledge. Educational media can use leaflets because they can be stored for a long time, targets can adjust and learn independently, users can view the contents during leisure time, wider target reach. The research objective was to determine the effect of education using leaflet media about exclusive breastfeeding on knowledge in pregnant women TM III at Tri Karya Mulya Health Center, Mesuji District in 2024. Quantitative research type with pre-experimental design with one group pretest-posttest. Population was all pregnant women TM III with a sample of 40 respondents taken by purposive sampling technique. The research was conducted at Tri Karya Mulya Health Center, Mesuji District in August 2024. Data collection used questionnaire sheets. Analysis was univariate and bivariate (Wilcoxon test). It was found that knowledge of pregnant women TM III before being given education using leaflet media was 60.6 and after was 89.3. There is an effect of education using leaflet media about exclusive breastfeeding on knowledge in pregnant women TM III (p-value = 0.000). Suggestions to health center staff and cadres to optimize the use of leaflet media in promoting exclusive breastfeeding to pregnant and breastfeeding mothers, pregnant women can seek information related to breastfeeding from health workers or the internet.

Abstract

Chronic Energy Deficiency (CED) in pregnant women increases the risk of delivery complications, maternal mortality, and fetal health problems such as LBW, prematurity, and birth defects. The prevalence of CED in Lampung Province for ages 15-49 years was 5142 cases, with cases in South Lampung Regency totaling 746 cases or 14.5%, ranking third highest among 15 Regencies in Lampung Province. To improve the nutritional status of pregnant women with CED, Supplementary Food Provision (PMT) needs to be given to pregnant women. Red bean extract is rich in protein, iron, and fiber which helps improve the nutritional status of pregnant women with CED. This study aims to determine the effect of Supplementary Food (PMT) red bean extract on the body weight of pregnant women with CED. This is a quantitative research with pre-experimental design with one group pretest-posttest design. A sample of 20 people was taken by Total sampling with the method of giving red bean extract 2x1 in the morning and afternoon for 14 days. This research was conducted in the working area of Way Urang Health Center. Data collection used observation sheets, and analysis used paired T-test. Based on the research results, the average body weight of pregnant women with CED before being given red bean extract was 48.62 kg and after being given red bean extract became 49.45 kg. Thus showing there is an effect of supplementary feeding of red bean extract on weight gain in pregnant women with CED in the working area of Way Urang Health Center, South Lampung Regency with p-value = 0.000. Pregnant women are expected to consume red bean extract regularly as a source of protein and iron to increase body weight and nutritional status of mothers with CED.

Abstract

This research is motivated by damage to hair which causes hair loss. Several Padang State University students experienced abnormal hair loss. The way to treat hair loss is to use shampoo made from flower extract. The aim of this study was to analyze the effect of hair loss treatment using cosmetic hibiscus extract shampoo at a frequency of 2 days once and 3 days once used. This research uses pure experimental methods. The sample in this research was 6 cosmetology and beauty students from the class of 2023. Data collection techniques use observation methods, documentation and assessment sheets. The data analysis technique used is the normality test, homogeneity test and independent sample test with SPSS 26. The normality test results show a sig>0.01 value, namely 200, which is normally distributed. In the homogeneity test results, the value of sig>0.01, the Levene statistic result is 1.066, indicating that the results have a homogeneous variance. The results of the independent simple test using spss26 were nil. ai sig >0.01, namely 0.660, shows that there is a comparison between the effect of using shampoo from hibiscus extract in the 2 day 1 treatment with the 3 day 1 treatment. From the results of the effect of using hibiscus extract shampoo, treatment 2 days 1 time is more effective or faster to prevent hair loss.

Abstract

Production planning is one of the most important factors in improving business continuity. The preparation of production planning is related to the optimization of production for a particular business so that the business can operate efficiently and production activities achieve competitive prices. The preparation of production planning must consider several factors because every business has different goals that it wants to achieve. The Goal Programming method aims to minimize deviations from the targets set by the business, so that business goals can be achieved optimally. This research aims to optimize production in a company that can accomplish more than one goal. The method used in this study is Systematic Literature Review (SLR), and this study identifies 5 previous journals. The source of information used in this study is articles from national journals published between 2018-2024. The results of this study show that Goal Programming is a very effective tool in production and distribution planning in various industrial sectors.
