Areas in Indonesia are prone to earthquakes, so it is necessary to plan a structure that can withstand the lateral forces caused by the earthquake. Shear walls are very effective in resisting lateral forces due to their high stiffness. The purpose of the study was to determine the effect of the location of shear walls on structures subjected to earthquake loads according to SNI 1726-2019. 7 structural models were created, namely 1 model without a shear wall and 6 models plus a shear wall with the same area and location which were divided into 2 models each in the core area, transition area and edge area and analyzed with software ETABS. Results of analysis are time period, story drift and moments of column in all models are then compared. Obtaining the value of the small time period by placing the shear wall at the edge of the building, with the highest stiffness value. Obtain the value of the story drift in the direction of the small long axis by placing a shear wall in the core area of the building, with a relatively small stiffness value. While value of the short axis deviation story drift by placing a shear wall in the transition area with a small stiffness. Small column moments value by the location of the shear wall in the transition area has the smallest maximum column moment value with a relatively small stiffness. The rigidity of the frame structure is greatest by placing shear wall at the edges of the building.

Road pavement is one part of road construction. Teluk Bua Road is a very important transportation route for the growth path of various aspects in Katingan Regency. Based on observations made, the Teluk Bua road section is often damaged. Types of road damage that occur include rutting, settlement, and upheaval or swell are characterized by bumpy road surfaces with damage levels from mild to severe. This study aims as a literature study to analyze the performance of the composition of the resulting mixture and analyze the value of free compressive strength of the resulting mixture, as well as to determine the stages of implementation in the field. One of the innovations in cost savings, the Cement Treated Recycling Base (CTRB) method is used in road foundation layer work. In the plan, there are variations in cement content of 7% to be reviewed, namely: The results of the study on the free compressive strength of CTRB cylinders with cement variation materials can be known from the mixture of Existing Material Ex. Teluk Bua (RAP) 65% + Additional Material Foundation Layer Class A Ex.Hampangen 35% + 7% cement added material which is 31.21 kg/ cm2. From this graph, the value of Dry Content Weight (MDD) used is 2.159 gr/m3, Optimum Water Content (OMC) is 6.44%. From the calculation results, the CBR Value of Plan = 86.33%.

Colleges function as learning centers that provide interactive academic environments. The Palangka Raya College of Informatics and Computer Management (STMIK) as the location of the research as a higher education institution located in Palangka Raya City, Central Kalimantan Province. The STMIK Palangka Raya building is designed to provide facilities that are in accordance with academic needs and accommodate teaching and learning activities for students, lecturers, and administrative staff focusing on informatics and computer management. The purpose of the study was to conduct a survey and analysis of the STMIK Palangka Raya building. The research method uses a qualitative method with a descriptive description of the results of the STMIK Palangka Raya building survey. STMIK Palangka Raya is designed with attention to the principles of security, accessibility, and user comfort. STMIK building materials used are of high quality and pay attention to energy efficiency. The research stages include analyzing the potential existence of STMIK, conducting visual observations and analyzing the availability of natural lighting in the STMIK building as an important factor because it affects the teaching and learning process related to the visual comfort of users of the space. Analysis of learning space as an analysis of the identification of campus building designs that provide student learning interest and analysis of green open spaces (parks) to create a beautiful learning environment and create fresh air. The output of the research is the identification of the location, structure, facilities, and lighting of STMIK Palangka Raya described in writing.
