Abstract

Mathematics is an important subject whose applications were widely used in life. However, many students have difficulty in learning mathematics, including elementary school students. This study aimed to examine the depth of Jean Piaget's cognitive development and Lev Vygotsky's sociocultural theory and their implication for mathematics learning at elementary school age. This study used a qualitative approach with the literature study method. Sources of data in the form of books, journals, and the results of previous research related to research problems. Data collection in this study was carried out using online searches. Data analysis was done by content analysis. The results of this study indicate that according to Piaget's theory of cognitive development, the thinking stage of students in elementary schools was generally in the concrete operational stage. So that the recommended mathematics learning was in the form of student-centered active learning such as discovery learning and contextual learning methods. Meanwhile, based on Vygotsky's sociocultural theory, he recommends cooperative and collaborative mathematics learning as well as optimizing the existence of scaffolding and social interaction in learning.

Abstract

Naturies Indonesia is one of the UMKM for spice drinks in Macanan, Klaten, Central Java which is developing. As one of the growing UMKM, Naturies Indonesia is experiencing problems related to the distribution of its products. Naturies Indonesia has incurred transportation costs of Rp.442,100.00 per week in distributing its products to 5 distributors (Kudus, Jakarta, Shopee, Bandung, and offline). Due to human resource constraints, Naturies Indonesia does not yet have a thorough plan to reduce shipping costs in allocating products from production sites to customers or distributors. Through this applied research, this research aims to find the optimization of product delivery costs. Data were collected through interviews and documentation, then analyzed using the Northwest Corner and Vogel's Approximation methods. Analysis using the Northwest Corner method found a shipping cost of IDR 431,600.00, while the Vogel's Approximation method found a shipping cost of IDR 427,900.00. The shipping costs found were actually lower than the financing that had been issued so far.  Keyword: northwest cor, spice drinks, optimization of transportation, UMKM Naturies Indonesia, vogel’s approximation

Abstract

Learning becomes less interactive when students are learning to build space because they focus more on the teacher's explanations. Students' mathematical character and problem-solving skills cannot be developed by this learning. An alternative for helping pupils improve their mathematical character and problem-solving skills is the TGT learning approach. The two cycles of this classroom action research project are designed to enhance students' mathematical character and problem-solving skills. Group intelligence was used in conjunction with the TGT model at SMP Negeri 4 Klaten class VIII. Students take a pretest to ascertain their starting abilities before class action starts. With only 3% of pupils completing the pretest, the outcomes were still quite poor. Students' ability to solve mathematical problems improved when they took action.Likewise, students' mathematical character has improved, namely in cycle I only 59% of students have mathematical character in the moderate category, while in cycle II as many as 78% of students have mathematical character in the good category.
