Abstract

Technological progress speeds up human movement, the distribution of goods, and service provision. PT JNE, a prominent firm in Indonesia, concentrates on delivering goods swiftly and with comprehensive services.. On the other hand, problems include daily changes in delivery, delays, less than optimal routes, and expensive gasoline. The shortest ideal route for the transportation of products is found using dynamic programming and a backward recursive equation technique in this study. The Medan Belawan District as well as the JNE Medan Representative Office provided the data that was used. The findings show that a route of a → f → d → c → g → b → e → h → a is the ideal total distance for goods delivery using a dynamic programming graph is 12,2 km, with an average courier covering 16,5 km. Based on data analysis, this shows a 26% increase in efficiency over the current routes. The layout of the routes makes it easier for couriers to choose the fastest route.

Abstract

Molluscs are one of the most abundant invertebrate animals and live on various substrates. Peh Pulo Beach has a wide coastline, on the edge of the beach there are coral rocks, the sand is white, and the waves are big. Molluscs like to live in coral rock substrates. This research aims to determine the diversity, evenness, and richness of molluscs on Peh Pulo Beach. Sampling was carried out at three different stations using plots measuring 1x1 m which were chosen randomly. Mollusc samples were identified based on morphological characteristics and validated using the WoRMS database. The results of mollusc identification at Peh Pulo Beach showed that there were 37 species belonging to 23 families. They are classified in the classes Gastropods (32 species), Bivalves (3 species), and Polyplacophora (1 species). The diversity of molluscs in the Peh Pulo Beach area is at a moderate level. The evenness of molluscs in Peh Pulo Beach is similar. And the richness of molluscs is at a semi-disturbed level so appropriate management and conservation strategies for the sustainability of molluscs are needed.

Abstract

The use of e-modules in mathematics learning significantly aids both teachers and students in the teaching and learning process. However, the design of e-modules has not been extensively linked to the cultural context in which students live. Therefore, this study aims to explore and analyze the needs of teachers and students in developing culturally integrated e-modules, particularly those reflecting the culture of Papua, for high school students. The research design employed is phenomenological. Participants included Mathematics teachers for grades X, XI, and XII in Nduga Regency, Papua Highlands, and 64 high school students (42 male and 22 female). Data collected from observations and interviews were qualitatively analyzed using Miles-Huberman Interactive Analysis. Findings revealed that the high schools still use the 2013 curriculum, relying on standard textbooks as teaching materials. These textbooks pose problems for students as they are often uninteresting, use formal language, are difficult to understand due to abstract content, and are not contextualized to students' daily lives. Additionally, the reduction in face-to-face learning hours, due to the school's location in a conflict area, hampers effective teaching and learning processes. Another interesting finding is that high schools in Nduga Regency have not yet utilized technology in learning, despite having internet access. These findings imply the need for teaching materials integrated with technology and local culture to help students understand mathematics concepts and assist teachers in teaching both inside and outside the school.

Abstract

Graphs are basic structures that represent objects with nodes and relationships between objects with edges. Trees are one of the parts studied in graph theory along with finding the number of spanning trees of a graph such as octopus graph, friendship graph, and snail graph. The complexity of an octopus graph is strongly dependent on the number and length of tentacles, the complexity of a friendship graph is dependent on the number of triangle cycles, and the complexity of a snail graph is dependent on the number of edges and vertices located in the shell-like part of the snail. To calculate the number of spanning trees (τ(G)) of a graph, various calculations can be used, such as the extension of Kirchhoff's formula. The extension of Kirchhoff's formula uses the determinant of the adjacency matrix and degree matrix of the graph complement of a graph. Therefore, this research applies the extension of Kirchhoff's formula to obtain the complexity of octopus graph, friendship graph, and snail graph. From the analysis, it is obtained that for any n≥2, the number of spanning trees of octopus graph and friendship graph are τ(On )=1/5 √5 [((3+√5)/2)^n-((3-√5)/2)^n ] and τ(Fn )=3^n and the number of spanning trees of snail graph is τ(SIn )=2^(n+2)+3n∙2^(n-1) for n≥1.

Abstract

The science process skills possessed by students are still in the low category. This is caused by a lack of learning activities that facilitate students to train and develop their existing science process skills in learning. This research aims to determine the improvement of science process skills through the application of the CCDSR learning model to static fluid material. The method used in this research is a quantitative method with a one group pretest posttest research design involving class XI MIPA students with a total of 31 participants. Data collection was carried out using scientific process skills test instruments and then analyzed using normality tests, homogeneity tests, hypothesis tests and N-Gain tests assisted by IBM SPSS version 29 software. Based on the results of data processing, the significance value of the normality test for the pretest was obtained at 0, 10 < 0.05, while for the posttest it was 0.086 > 0.05. Then, the homogeneity test has a significance value of 0.555 > 0.05, and the t test is <0.001. Meanwhile, the average increase in science process skills obtained from the N-Gain test was 0.62 in the medium category. Based on the results of the analysis, it can be concluded that applying the CCDSR learning model in learning can improve students' science process skills in static fluid material.
