Abstract

Mathematical disposition is an affective ability that is important for students to have because through this ability, students' attitudes in facing problems in mathematics will be resolved properly. One of the efforts that can be done to improve mathematical disposition is by implementing problem-based learning. By providing contextual problems in mathematics learning, it can have an impact on interest, desire and awareness in the form of a strong tendency to think and behave towards mathematics and see the usefulness of mathematics. This research aims to analyze students' mathematical disposition using problem based learning.This type of research is Quasi-experimental research.This research was implemented at SMP Negeri 1 Pangkalan Susu. The population of this research was students of class IX. The sample used was students of class IX-1 as the experimental class and IX-2 as the control class. Based on the results of t-test used in the research, the t-count value was 3,508 and the t-table value for a value of 1.67. This means that the t-count value > t-table namely 3,508 > 1,67. The results of this research state that the mathematical disposition of students who use problem-based learning is better than the mathematical disposition of students who use conventional learning.

Abstract

The development of information technology encourages business actors, including Micro, Small, and Medium Enterprises (MSMEs), to utilize information systems to improve operational efficiency and customer relationship management. Customer Relationship Management (CRM) is a strategy used to manage interactions with customers in order to increase customer satisfaction and loyalty. However, many MSMEs still record customer data and sales transactions manually, resulting in less effective data management processes. UD Sri Tani is a business engaged in the sale of agricultural products that still manages customer data, product inventory, and sales transactions manually. This condition causes difficulties in monitoring customer relationships and developing effective sales strategies. Therefore, this study aims to implement a web-based Customer Relationship Management (CRM) system to improve customer management and support sales strategies. The research method used includes system requirements analysis, system design, system implementation, and system testing. Data collection was conducted through observation, interviews, and the distribution of questionnaires to 39 respondents consisting of customers and business managers. System testing was carried out using the Black Box Testing method to ensure that all system functions operate according to user requirements. The results of the study indicate that the developed CRM system is capable of integrating customer data, product data, and sales transactions in a centralized manner. Based on 15 testing scenarios, all system functions showed a 100% success rate, indicating that the system operates properly according to user needs. The implementation of this system helps business owners manage customer relationships more effectively and supports the improvement of agricultural product sales strategies at UD Sri Tani.
