Abstract

CKS charcoal is waste from burning CKS as operational fuel for Asphalt Mixing Plant (AMP). Hampangen clay and CKS charcoal are usually used as raw materials for non-conventional cement mixed with fine aggregate and coarse aggregate which are usually used in the Palangka Raya City environment. Several studies have been conducted by utilizing industrial by-products as non-conventional cement and made as a geopolymer concrete mixture. The geopolymer concrete mixture uses aggregates that are usually used in Palangka Raya City.This study aims to determine whether by adding conventional cement partially and fully to a mixture of non-conventional cement made from Hampangen clay and CKS charcoal can produce a geopolymer concrete mixture that is maximum in terms of the compressive strength of the concrete produced. The method used is the calculation of the mix design calculated using the ACI method (meaning in conditions of adding conventional cement fully - 100%). Based on the results of the study, it is known that the addition of PCC cement, the Gresik brand, in a mixture of geopolymer concrete made from CKS charcoal and Hampangen clay on the compressive strength of concrete is categorized as very strong.

Abstract

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.

Abstract

With the history of earthquakes that occurred in Central Borneo Province, it is very necessary to plan earthquake resistant building structures, especially in the implementation of reinforced concrete building structures. Earthquake-resistant reinforced concrete structure planning is carried out using a Special Moment Resisting Frame System with the object of research being the Integrated Lecture Building of the University of Palangka Raya. In planning earthquake-resistant reinforced concrete structures, the requirements described in SNI 2847-2019 are required. The results of the planning of structural components for the structure of the Palangka Raya University Integrated Lecture Building, namely the structural components under review, used 30/60 beam dimensions and 60/60 column dimensions. In the 30/60 beam design, the left bearing reinforcement is 6D25 tension-8D29 pressed, the field reinforcement is 4D25 tension-2D29 pressed, the right support reinforcement is 5D25 tension-4D29+4D25 pressed, and the left/right joint shear reinforcement 2 legs ∅12–120 mm for the plastic hinge area and 2 legs ∅12–150 mm for the area outside the plastic hinge. On the planning of the 60/60 column obtained longitudinal reinforcement 24D25 and reinforcement in the plastic hinge 4 legs ∅12–100 mm, outside the plastic hinge 4 legs ∅10–150 mm, and in the lap joints 4 legs ∅12–100 mm. On examination the requirements for strong column-weak beam based on SNI 2847-2019 have been fulfilled. So that the planning of the Special Moment Resisting Frame System in increasing the resistance of the building to the possibility of large earthquake forces is appropriate and safe.

Abstract

The Kahayan River is able to attract the attention of tourists and the people of Palangka Raya City through its natural potentials and portraits of community life on the riverside area. The Kahayan River has natural potential such as rivers, green open space, as a city buffer area, as well as cultural tourism, namely the uniqueness of settlements on the riverside area. The purpose of the service is to map the natural tourism potential of the Kahayan River area, Pahandut Seberang Village. The activity is located in Pahandut Seberang Village, Palangka Raya City. The method used is qualitative by describing descriptively and the stages of activities include: (a) preparation stage; (b) implementation stage; (c) post-implementation stage. The analysis and synthesis include descriptive elaboration of in-depth interview data with the community and village civil servant and the results of observational studies. The analysis applied to service activities include: (a) mapping analysis of the existing potential of the area, (b) mapping analysis of river tourism potential in Pahandut Seberang Village, (c) figure ground analysis of tourism potential in the Kahayan Riverside area, and (d) analysis of green open space tourism in Pahandut Seberang Village, Palangka Raya City. The output of this service activity provides a learning process for mapping the potential of natural tourism, analyzing the identification map of natural tourism, and analyzing the concept of nature tourism in Pahandut Seberang Village based on sustainable local wisdom.
