One way to solve problems in mathematics is to think algebraically. Algebraic thinking is thinking using generalization abilities, transformational abilities, and global meta-level abilities to solve problems. A person's ability to overcome and solve problems is called Adversity Quotient (AQ). There are three categories in Adversity Quotient (AQ): climber, camper, and a quitter. This study aimed to describe the profile of students' algebraic thinking in solving mathematical problems in terms of Adversity Quotient. This research is qualitative research with the subjects of this research are three grade IX junior high school students with different AQ categories. The instruments in this study were Adversity Response Profile (ARP) questionnaires, Problem Solving Tests (TPM), and interview guidelines. The qualitative data analysis technique follows the Miles and Huberman concept, which consists of three stages: data reduction stage, data presentation, and conclusion drawing. This study indicates that climber students perform all stages in solving problems and fulfill all indicators of algebraic thinking. Camper students did not carry out the re-examination stage in solving problems and only carried out generalization activities in algebraic thinking. Quitter students do not perform the steps in solving problems and do not fulfill all the indicators of algebraic thinking.

This study aims to determine the mercury accumulation in Gerris sp and its potential as a bioindicator. This type of research is experimental research. This research was conducted at Lake Taliwang and the UGM Integrated Research and Testing Laboratory. The sampling point in this study was determined based on the distance to the pollutant source. It was divided into station 1 (inlet), an area close to the pollutant source, and station 2 (outlet), far from the pollutant source. There are 3 test tests: the accumulation of mercury in water and sediment, mercury in the gerris, and the gerris as a bioindicator of mercury pollution. Analysis of the test results data is presented in descriptive statistics. The results of this study are (1) The waters of Lake Lebo are polluted by mercury, found in sediments and water, and enter the food chain, namely gerris. The mercury concentration in the inlet area is greater than the outlet area because it is closer to the pollutant source (2). Gerris can be used as a bioindicator of mercury pollution in Lake Lebo Taliwang because it can accumulate heavy metals. It meets the criteria of bioindicator organisms and is very strongly correlated with water. The finding suggests that the local government makes regulations regarding mercury metal pollution in Taliwang Lake because mercury metal can enter other food chains and is toxic to living things.
