Abstract

Kini masyarakat telah beralih menggunakan e-commerce untuk memenuhi kebutuhan hidup mereka melalui belanja online. Promosi influencer merupakan salah satu penyebab seseorang melakukan impulsive buying, yaitu pembelian yang tidak rasional dan terjadi secara spontan pada saat itu juga. Perilaku ini jika dilakukan secara berulang akan menimbulkan Compulsive Buying Disorder (CBD) atau yang biasa disebut sebagai kecanduan belanja. Adapun tujuan penelitian ini adalah membangun model matematika, menentukan titik kesetimbangan dan bilangan reproduksi dasar, menganalisis titik kestabilan titik kesetimbangan, serta melakukan simulasi numerik menggunakan Maple. Pada penelitian ini model dibagi menjadi lima populasi yaitu subpopulasi Potential, subpopulasi Medium Compulsive, subpopulasi Influencer, subpopulasi High Compulsive, dan subpopulasi Recovered. Dari hasil analisis kemudian diperoleh dua titik kesetimbangan yaitu titik kesetimbangan bebas CBD dan titik kesetimbangan terdapat CBD yang stabil asimtotik lokal. Berdasarkan hasil simulasi diketahui bahwa perubahan pada peluang influencer dalam mempengaruhi individu medium compulsive melakukan impulsive buying $(\theta)$ memberikan pengaruh signifikan terhadap nilai bilangan reproduksi dasar $(R_0)$ dan titik kesetimbangan yang diperoleh. Semakin tinggi nilai $\theta$ maka semakin cepat meningkat juga jumlah individu yang menderita CBD (high compulsive) dan semakin cepat menuju titik kesetimbangan pada waktu t.

Abstract

Abstract: The numeracy of 10th-grade students at SMAN 3 Slawi is still not optimal and needs improvement. This is because students are not accustomed to dealing with non-routine problems. This research aims to determine the effectiveness of the STEM-based MURDER learning model assisted by Quizizz in improving students' numeracy. In this study, the proportion test of student completeness obtained a Sig. value of 0.004, indicating that the proportion of students class experimental exceeded the classical completeness, reaching 42%. In the test of average differences, a Sig. value of 0.004 was obtained, meaning that the numeracy ability of the experimental group was higher than control group. In terms of improvement, the N-Gain test resulted 0.28, which falls into the interval 〈g〉 < 0.3, indicating that the improvement in students' numeracy using the STEM-based MURDER learning model assisted by Quizizz is relatively low. Keywords: numeracy, STEM, MURDER, quizizz. Abstrak: Numerasi siswa kelas X SMAN 3 Slawi masih belum optimal dan perlu ditingkatkan, hal tersebut terjadi karena siswa tidak terbiasa dengan permasalahan berupa soal non-rutin.

Abstract

Tuberculosis is an infectious disease caused by Mycobacterium Tuberculosis. Tuberculosis patients undergoing long-term tuberculosis treatment have a high risk to get asthma as a second infection. A person suffering from asthma cannot recover. Asthma therapy is only to control the development of asthma so that asthma does not get worse. In this study we discusses the spread of tuberculosis with asthma as a secondary infection. We perform the model into system of non- linear differential equation that consist of six equation because the population divided into six sub-population which are susceptible, infected by tuberculosis, undergoing tuberculosis treatment, infected by asthma, undergoing asthma treatment and recovered from tuberculosis. From the model that has been formed, we perform the analysis to obtain the equilibrium point and the basic reproduction number. Then we show the local stability of the equilibrium point and perform simulations to provide an illustration. From the analytical result, we got that the spread influence by recruitment rate, infection rate, natural death rate, tuberculosis treatment rate and death rate because of tuberculosis.

Abstract

Purpose: This study aims to examine the effects of differentiated instruction on primary students’ mathematics achievement in the Indonesian context by comparing learning outcomes between classes taught with differentiated instruction and those taught with conventional methods.Method: This quantitative study employed a quasi-experimental, non-equivalent control group design with two intact grade 4 classes from a primary school in Indonesia. The experimental class received differentiated instruction based on students’ readiness, interests, and learning profiles, while the control class received conventional teaching. Data were collected using a validated mathematics achievement test with acceptable reliability. Assumptions were checked, and independent-samples t tests compared posttest achievement between groups.Findings: Students taught with differentiated instruction obtained significantly higher posttest scores than those in the control class, indicating a positive effect on mathematics achievement.Significance: The study provides empirical evidence that differentiated instruction can improve primary mathematics achievement in Indonesian classrooms. The findings offer practical guidance for teachers and inform school leaders and policymakers seeking strategies to enhance learning outcomes

Abstract

The problem of congestion has become a common problem that is often found on the highways, especially at the crossroads, without exception in Jepara Regency. The Mayong-Jepara Highway intersection is classified as a busy intersection that is full of vehicles during every departure and return hours, which are dominated by factory employees. Congestion often occurs at these intersections even though there are traffic lights that regulate the movement of vehicles. So, This study aims to find the solutions to congestion problems at Mayong-Jepara Highway intersection through compatible graph modeling and optimizing traffic light cycle time using the Webster method. Compatible graphs are used to determine traffic flows that are worked to move simultaneously without causing collisions, and that are used to carry out the graph weighting to determine the number of phases. The variables used in this applied research are the data on the number of vehicles, road width, and traffic light duration that taken directly in the field. Because the traffic density in the morning and afternoon is different for each intersection arm. Thus, the cycle time is determined in 2 sessions namely the morning and the afternoon. From the modeling of the compatible graph that has been weighted, it is obtained that the morning and afternoon sessions have 3 phases as the total which are then used to determine the traffic light cycle time. As a result, the cycle times for the morning session are 98 seconds, and the afternoon session is 155 seconds. The results were then simulated with PTV Vissim software and assessed to be quite effective in dealing with congestion and heavy traffic at the Mayong-Jepara Highway intersection especially in the afternoon session.
