Abstract

Sejak tanggal 26 Desember 2019, Pemerintah Kabupaten Jember, Jawa Timur kembali menetapkan status kejadian luar biasa (KLB) untuk penyakithepatitis Aatau peradangan hati yang disebabkan oleh infeksi virus hepatitis A (HAV). Penyebaran Infeksi Virus Hepatitis Aini dapat di Analisa menggunakan model matematika SIR (suspected, infected, dan recovered). Dari model SIR didapat dua titik kesetimbangan yaitu ????1=(????????,0,0)dan ????2=(????+????+????????,????????+????+????−????????,????????????(????+????+????)−????????)yang berguna untuk mengukur tingkat penyebaran virus. Sedangkan untuk menganalisis kestabilan, digunakan linierisasi matriks jacobi. dengan nilai eigen????1=−????dan????2= β–????-ɣ-δ. Simulasi model SIRpada penelitian ini menggunakan data penderita Hepatitis AdiKabupaten Jember. Adapunhasil simulasi dapat disimpulkan bahwa akan terus terjadi peningkatan jumlah individu susceptibledan infecteduntuk penyakit Hepatitis A, sehingga dapat disimpulkan bahwa semakin berjalannya waktu penderita HepatitisAakan terus bertambah dan menjadi wabah.

Abstract

God’s crown (Phaleria macrocarpa) is a medicinal plant of Papua. Fruit flesh which is physiologically mature is used for pharmaceutical industry. Maturity index of the fruit can be observed from bright red skin and hard texture. However, the physiological changes of the fruit has not been widely studied. The purpose of this study was to assess changes in postharvest physiology in term of color and weight loss. The fresh fruit parameters observed were harvesting time, color, and uniform in size. The fruit is washed, then stored at room temperature, and observed physiological changes every 24 hours for 21 days until the fruit is damaged. Color parameters including index L, a, b were observed using Adobe Photoshop CS6, while weight loss is measured using digital scales. Data were processed by means of Microsoft Excel 2007. The results showed that the fruit color changed from green to red within 12-15 days of storage due to degradation of chlorophyll and synthesis of carotenoids. Weight loss increased during storage because of respiration and transpiration. Additionally, the fruit quality was drastically decreased as result of decay process, which is accelerated by the presence of pathogens.

Abstract

In this article, dynamics of predator prey model with infection spread in prey and cannibalism in predator is analyzed. The model has three populations, namely susceptible prey, infected prey, and predator. It is assumed that there is no migration in both prey and predator populations. The dynamical analysis shows that the model has six equilibria, namely the trivial equilibrium point, the prey extinction point, the disease free and predator extinction equilibrium point, the disease-free equilibrium point, the predator extinction equilibrium point, and the coexistence equilibrium point. The first equilibrium is unstable, and the other equilibria conditionally local asymptotically stable. The positivity and boundedness of the solution are also shown. The analytical result is supported by numerical simulation. It is shown that in such a high cannibalization the coexistence equilibrium is locally asymptotically stable.

Abstract

This study employs a qualitative approach to describe junior high school students' interpretative abilities in solving mathematical literacy problems. The sampling technique used in this research is purposive sampling. Credibility testing is conducted through source triangulation, which is used to test the credibility of data by cross-checking data obtained from several sources. The results of this study indicate that both subjects, S1 and S2, utilize real-world contexts to check the reasonableness of their answers, provide arguments, and set solution boundaries. However, the use of real-world contexts in interpreting mathematical literacy problems is insufficient to produce correct answers. Misinterpretation of the real-world context by both subjects leads to an inability to appropriately link mathematical concepts with their real-world applications. This study highlights that, in addition to using real-world contexts, a good understanding of mathematical concepts is essential for correctly solving mathematical literacy problems. Keywords: misinterpretation, real-world context, mathematical literacy problems

Abstract

The purpose of this research is to develop a Students' Working Sheet (LKPD) based on mathematical reasoning for 7th-grade students of UPTD SPF Junior High School 3 Bondowoso. In this study, Thiagarajan's development model (1974) is used, which consists of four stages: Define, Design, Develop, and Disseminate. However, the development of mind mapping-based LKPD is only limited to 3D. The initial observation shows that students have different levels of mathematical reasoning ability. The result of the study includes the validity, practicality, efficiency, and effectiveness of the LKPD. After being validated by two validators, the validity of LKPD is assessed, with 3,25 as the average score which indicates a good level of validity. The practicality of the LKPD was assessed by the teacher's questionnaire, which received 81,25% as the average score, which shows that the LKPD can be considered practical. The efficiency of the LKPD was assessed by the student’s questionnaire, which received 86,27%, which shows that the LKPD can be considered as efficient. Keywords: Students' Working Sheet, mathematical reasoning, mind mapping

Abstract

The aim of this research and development is to determine the quality of Student Worksheets (LKPD) based on Realistic Mathematics Education (RME) with an ethnomathematics approach as teaching materials that are suitable for use. This type of research is Research and Development (R&D) with a research model referring to the development of ADDIE (Analysis, Design, Development, Implementation, and Evaluation). The subjects of this research are 7th grade students of SMP Muhammadiyah 9 Watukebo with a total of 121 participants/students (pilih salah satu aja). Three types of questionnaires were used in this research, such as; validation questionnaire sheet, teacher’s response questionnaire as the practicality assessment, and student’s response questionnaire as the effectiveness assessment for the LKPD. Results of the data analysis are (1) validation score from two validators on developed LKPD obtained an average score of 3.85 which categorized as valid, (2) the practicality score of two teachers on developed LKDP obtained a mean score of 4.75 which categorized as highly practical, (3) effectiveness score from the learners on developed LKPD obtained an average of 4.551 which categorized as highly effective. Thus, the Student Worksheet (LKPD) based on Realistic Mathematics Education (RME) with an ethnomathematics approach in line and angle material is suitable for use.

Abstract

The aim of this research is to produce a product in the form of LKPD based on character education and Islamic values ​​which will help students more easily understand the content of the material. The method used in this research is the Research and Development (R&D) development method with the 4D development model. The results of this research are reviewed from the validity and practicality of the product. Product validity is obtained from the average score given by 3 validators on the validation questionnaire of 83.38 and is included in the interval > 80 and is categorized as very valid. Meanwhile, product practicality was obtained from the average score given by respondents through a small-scale trial stage with a total of 6 respondents who obtained a score of 66.2 and fell into the interval 60 - 79 and were categorized as practical. Meanwhile, a large-scale trial with 31 respondents obtained a score of 81 and was included in the interval > 80 and was categorized as very practical. Based on this, it can be concluded that the product that has been developed by researchers in the form of LKPD is very valid, very practical, and in accordance with students' needs
