When visiting several tourist attractions at once with limited time and an irregular schedule, of course, visitors choose the closest route to be able to visit all the places to be visited at once. This study uses an algorithm, namely the Kruskal algorithm, which aims to find the closest route to visit the five tourist attractions at once in Central Lombok Regency. The tourist attractions in question are Tanjung Aan Beach, Kuta Mandalika Beach, Sukarara Village, Sade Hamlet, Benang Kelambu Waterfall. This type of research is applied research which is generally a type of descriptive research that encourages further research. This study applies a modified Kruskal algorithm so as to produce 4 alternative closest routes with different starting points to be able to visit the five tourist attractions at once in Central Lombok Regency, namely 1) If the journey starts from Tanjung Aan Beach or Benang Kelambu Waterfall, the closest route is 60,1 km; 2) If the journey starts from Kuta Mandalika Beach, the closest route is 73.6 km; 3) If the journey starts from Sade Hamlet, the closest route is 73.6 km; 4) If the journey starts from Sukarara Village, the closest route is 82.9 km

Abstract Lack of knowledge in a number of teachers who are not able to operate the concept of learning well, namely teachers only rely on learning methods and strategies on the handbook or documents that have been received. The impact of learners has difficulty in solving problems. By utilizing the results of research on the development of mathematical learning tools in the form of teaching materials, LKPD, and RPP based on 21st century skills that are feasible to be used can solve the problem. Therefore, it is necessary to socialize and implement the results of the research to the community, especially teachers in junior high schools. the outer target of this agility is the understanding for teachers of 21st century skill-based learning tools, particularly mathematics and other subjects.

In the 2019 survey, 82.2% of teachers never participated in media training, especially learning media based on geogebra technology. Meanwhile, 92.8% of teachers stated that mathematics requires learning media. The low quality of education in NTB requires special attention from both the government and the private sector, so it is important to conduct technology-based learning media training in order to improve the quality of education, especially improving the quality of teachers. The training was carried out using offline and online methods for two days, 19 and 20 August 2021 at SMPN 16 Mataram. The training was attended by 22 participants from junior high school mathematics teachers in the city of Mataram. In the implementation of the training, an evaluation was carried out using questionnaires and observations. The conclusions from the results of the service were as follows: Geogebra training as a medium for learning mathematics for SMP teachers in the city of Mataram in 2021 received a very good response and was well received by the teachers. Geogebra training as a medium for learning mathematics for junior high school teachers in the city of Mataram in 2021 is very in line with what is expected by mathematics teachers in the City of Mataram and increases teacher competence in the context of applying technology in learning to develop technology-based mathematics learning media.

This community service activity aims to improve teachers’ abilities to create video lessons that could be used either on online learning or in person. The activity's strategy was a workshop that mainly focused on working and creating video lessons after giving a brief explanation on how to produce the video. The workshop also involves pre and post-test to assess the improvement of participants’ competence. This activity resulted in video lessons uploaded on the Youtube channel, and participants’ assessment scores improved from 65,8 to 76,9. Therefore, teachers involved in this social service admitted that they benefit from joining the workshop as they are now able to create exciting video lessons that might raise students’ enthusiasm and motivation in the learning process.

This study aims to determine the effect of the Thinking Aloud Pair Problem Solving (TAPPS) learning model on the mathematical problem solving abilities of eighth grade students of SMP. This research is a quasi-experimental research with Non-Equivalent Control Group Design. The population in this study were all eighth grade students of SMP. In determining the sample, the saturated sample technique was used, where the samples in this study were class VIII-A as the control class and class VIII-B as the experimental class. The instrument used in this research is a test of mathematical problem solving ability on number pattern material. Quantitative data analysis was performed using a gain t-test. The results of data analysis obtained thitung = 2.14 and ttable = 2.064 so that thitung > ttable then H0 is rejected which indicates that there are differences in students' mathematical problem solving abilities between classes that receive TAPPS learning and direct learning. This shows that learning with the TAPPS model has an effect on the mathematical problem solving abilities of eighth grade students of SMP. The influence of the application of the Thinking Aloud Pair Problem Solving (TAPPS) learning model on the mathematical problem solving ability of class VIII students at SMP on the number pattern material using the effect size formula (d) is 1.907, which means that the effect given has a high category.
