The research method used is descriptive qualitative. Data collection techniques in research using observation, interviews and documents. Data analysis procedure with the steps: data reduction, data presentation and conclusion. The results showed that there were errors made by students of class XI MIA SMA Al-Ikhlas Lubuklinggau in solving story questions about arithmetic sequences and series, namely: errors in understanding questions (49.99%), question transformation (50%), operation process (79.16 %) and writing the final answer (88.89%). The overall average error is (67.01%) with the high category. Based on the results of the interview the causes of students made mistakes, namely: students forgot and were unable to write information into mathematical symbols, did not know the formulas that should be used in the questions, were in a hurry because time was running out, were not careful, were mistaken in writing the operation signs, did not know which steps were must be done, forgetting to write down conclusions, and consider the final answer only to get the value that is sought. Keywords: Analysis, Errors, Problem Stories, Sequences and Arithmetic Series.

This research aims to develop worksheets to facilitate the ability to understand mathematical concepts in the material of one-variable linear equations, to determine the quality of worksheets developed in terms of validity and practicality, and to understand the ability to understand mathematical concepts after the use of LKS in one variable. The subjects were seventh grade students of Lubuklinggau 7th Junior High School. A development research that refers to the 4-D development model. In the Design phase includes: preparation of instruments consisting of validity LKS sheet, practicality assessment sheet LKS and test instruments for understanding mathematical concepts. Furthermore, the format selection consists of compiling the framework and systematic preparation of LKS, so that the prototype LKS is formed 1. Develop phase, the LKS is validated by mathematicians and experts, suggestions and comments from the validator are used as references in revising the LKS, thus producing a prototype 2. Next is LKS was tested in a small group and produced a prototype 3, then tested on a large group. The last stage is Disseminate, LKS products are distributed to class VII math teachers, principals, and grade VIII mathematics teachers. The quality of LKS developed based on the validity aspects is in the Good category with an average score of 4.0, while the quality of the LKS from the practical aspect is in the Excellent category with an average score of 0.84. In the test the ability to understand mathematical concepts is in the Good category with an average value of 80,966
